Hi Mike, I thought I would drop you a line about another easy build and cheap antenna design, it's for v.h.f./u.h.f. but can be scaled up to h.f.  As your web pages are used very often by myself, and quite a few other M3s and M6s that I know of in my area, as a great reference point for home brew antennas "a big thank you from me personally"

After the recent 100mph plus high winds here in the North of England, due to a dangerously bent pole, my 2m/70cm 4 element beam on the roof had to come down for safety reasons; I have been looking for an easy lightweight cheap home-brew (DIY) vertical antenna to replace it and relocate the beam to an easy access wall bracket on the side of the house. During my search I came across a very interesting webpage from down under (VK) which is well worth a look and could be a good antenna to include within your information. I hope it interests you.

Personally, so far, I have made a v.h.f. "slim jim" antenna, many end fed fishing pole HF verticals and a large fishing pole HF delta (which is also down after the winds) but definitely the best yet for my very poor RF location (QTH).

Hi Phil, Very many thanks for your email. I am glad that some of the pointers on my web pages have helped you and your friends.

When I first started out looking for a suitable antenna I did find it quite a daunting task to sift the wheat from the chaff, as it were. Ther is an awful lot of chaff out there - as you have probably found! I am very sorry to read that you suffered damage in the recent high winds. That must be very frustrating indeed for you.

I have a rather tall pole on the side of the house with a short 2/70 collinear mounted on top and I have to admit that I was certainly rather worried about it. However it survived I'm relieved to say. As a precaution before the winds arrived,  I had reduced the height of the sectionalised fibreglass Tecadi pole that I use to support my Inverted L, and reduced my telescopic aluminium mast that holds a vertical fibreglass collinear and a 2m / 70 cm yagi to its minimum height and lashed it down. They were both, thankfully, undamaged by the ferocious winds.

You seem to find fibreglass fishing poles as useful as I do! They really are great for both experiments and permanent installations. Thanks for the heads up to the http://vk2zoi.com site. The flowerpot looks very interesting indeed! I will have a good look through that information and put a link on the web pages. Great idea!

Thanks again for your really excellent email. Say hello to your fellow radio amateurs from me - and keep up your experiments. Brilliant stuff.

Cheers and 73

Hi Mike, After another trip down memory lane on your site I have something else to contribute to the BRMB pages. Firstly apologies, it wasn't Sue Foster in the newsroom but Sue Todd of course, the wife of the late John Russel. Blame my faulty memory.

2nd - you might be interested in posting the attached pic of me circa 1976 when I was in the newsrom.  See this page > .

3rdly - I note mention of George Gavin doing sport but whatever happened to George Reeves who assisted Tony Butler?

Re Tony Blackburn, I presume his stint at XTra-AM was short?
Whatever happened to Allan Nin?

Would love to hear from people like Rob Golding and Colin Palmer again. I will be in the UK in July for three months and would welcome the opportunity to catch up with any former colleagues at BRMB 1975-1977.

Regards,
John Rogers.
BRMB Newsroom, Aston Cross, 1975-1976.  [January 2012]

Hi John, Many thanks for the photograph and more thoughts about BRMB. I hope that more BRMB people will get in touch and help answer your questions - so let's through it out and kick it around! Please get in touch here >

It's such a shame that BRMB has pretty much met it's demise in all but name - and that could go by April 2012, if it's not all a desperate publicity stunt by a now beleaguered management!  So sad.

Thanks again John. All the best, Mike.



Hi Mike, 

Some stations in the UK came through in the summer of 2000 here on the
island of Oland in south east Sweden.

Here is a recording from  June 11th 2000 on 96.4 MHz vhf/FM at 19:38 hrs:  
Audio file: BRMB received in Sweden in year 2000

Who is the nice presenter in this audio clip?

Best wishes,
Kjell Tunsater.
FM radio enthusiast.

[January 2012]

Hello Kjell, Thanks for your email and the audio recording.

The voice sounds like Stuart Ellis to me - but I have my doubts about that because I think Stuart Ellis had left BRMB by 1998, unless he was doing a 'stand in'. So, I think that it must be someone else, but I am not sure who.

I must admit that my enthusiasm for BRMB was fading by 2000. Capital Radio had bought the station some years previously (now sold on again) and the station was never as good again as it once was. I was listening occasionally in 2000 (always to the Breakfast Show with Les Ross), but I cannot accurately remember the names that were on air at that time.

It's amazing to think that you heard a local station so far away in Sweden when there must be so many other stations using 96.4. Some Sporadic E ?

I will try to think some more about that voice! In the mean time I wish you well and Good DX!

Best wishes, Mike.
P.S. I just found some air checks of Stuart Ellis on his website. Visit Stuart's website and click on "Audio Archive" and see what you think. http://www.stuartellis.co.uk

Does anyone know better. Please contact us here. Thanks!



Hi Mike,  I absolutely loved your site regarding choices between the various multiband antennas, I thought the attention to detail was wonderful... Mind you, I'm still as confused as ever as each individual lot is obviously different?

Thank you so much for all the graft you have obviously put in,

Best regards, Mark, M6AWG [January 2012]

Thanks very much Mark - There's certainly plenty to choose from!  Best wishes, Mike.



Hi Mike, I just ran across your website, and as a fairly new ham, I want to thank you for putting so much information into one convenient page. I am just scratching the surface of your site, and look forward to spending much time sorting through all the info. I also really like your Ham station. Due to space limitations (i.e. children) , I have been forced into a small corner of my home, and it is nice to see someone running a quality station from such small corner. Now I realize I need to take my station equipment vertical, instead of horizontal!

Thank you again for the time you have put into your site. I hope to work you on the air sometime.

Best Wishes, Fred Lomax KK4BAW  [January 2012]

Dear Fred, Thank you very much indeed for your email, it's really great to hear from you. I am glad that you have found my page of interest and I hope that it may be of help to you. As you have seen, space is certainly a problem for me, both in the shack and for antennas outside. Nevertheless I have managed to squeeze it all in somehow!

I am glad that you like the idea of going vertical. It really was the only scheme that could work for me in the limited space. Good luck with you station - maybe you can tell me how you get on with arranging your shack in the future.

Thanks again. Mike.

Thanks Eric I am glad that I could help you get your discs spinning again so that you could play some of your favourite music.



Amateur Radio Station 2QW - photograph submitted by Peter G3THW Hi Mike, I wonder if you can help with a problem. I have attached a picture of an old amateur radio station who I believe to be a relative of my brother-in law John G3PTO. John G3PTO  (a QRP enthusiast) sadly died a couple of years ago. The station is possibly that of 2QW which I believe was located in the West Midlands area. Can you help with identifying the approximate date of the picture from the equipment or provide any further leads?

The photograph was possibly taken before the start of World War 1, and may be of 2QW which was possibly the first licenced radio amateur in the Wolverhampton area. This photograph is believed to show his West Bromwich home. He was my father's uncle, and the morse key is still in use by myself, having been passed down to me when 2QW became a silent key.

Your comments would be much appreciated.
73, Peter G3THW. 
[ December 26th 2011 ]


Hi Peter, Many thanks for your email, the photograph is fascinating.

I honestly cannot date the image, but as you've already guessed I certainly could be from the 1920's. You have probably seen the 1920's Wireless Maps of Great Britain produced by The Wireless Press Limited on the website. The callsign certainly fits in with that era, though it is not actually mentioned on the map. The photograph of station VE2BV from 1936, also on my website, shows some early radio equipment, which bears some similarities.

Sadly, however, I have no other information. A search of Google appears to draw a blank too - as you will have no doubt discovered. If anything else springs to mind I will be sure to let you know.

If anyone reading this has more information on 2QW and any other very early amateur radio stations please do contact us. Thanks.

Best wishes, Mike



Hi Mike, I suppose it's 'Men of a certain age' but over the last couple of years I keep finding your site. I'm a Radio Amateur (G8ZWN), have an interest in pirate radio, have just got a SL1200 and I've had cats all my life and would not be without one (or 2).

Thanks for a great site and a great resource. Out of interest what Turntable mat do you use on your SL1200, mine still has the dodgy slip mat and plastic thing from it's former life as a home DJ deck. The accompanied picture was put on face book entitled 'My Cat's A Ham' and some said I set it up but I didn't. Sadly this fellow isn't with me anymore but he was a good puss and his memory lives on.

Best Regards
, Michael Barrett Davies. [December 2011]

Hi Michael,  Many thanks for you kind words. We do seem to have very many things in common!

I use the standard Technics platter mat on my turntable - it's not a DJ slip mat, just standard rubber, but quite thick. I love the photo of your beautiful cat - such characters aren't they! A sad loss. We love the photograph of your cat - thanks for letting us include it on the site.

Thanks again, Mike.

Hi, I'd love you to have a picture of my old mate on the site, attached is another. I won't bombard you but I have a lot of pictures af cats that have a definite interest in technology so If I send any your way feel free to do what you want with them. Some time ago when I buried an old cat i read something on the web which went along the lines of 'Remember me in the same way you did as when I was alive' and I do for all of the things I have loved that have moved on'.

Best Regards, Michael Barrett Davies.

Thank you! We'll put your wonderful photographs on the site soon. Best wishes, Mike and Jules



[Regarding the Vinyl Heaven pages] - Hi, I wonder if you can help me?  My husband has recently dug out all his old vinyl and his old record deck - couldn't tell you what make it is but it's a pretty good one.  Anyway we went to try and plug it into our Yamaha CRX-330 mini hifi system only to discover it doesn't have a turntable input (Pre-amp) to enable us the two together.  To be honest we're quite happy with a little hifi but it could do with updating and I'd like to buy one for him for Christmas which has a turntable input - any advice?

Hope you can help. Gill 
[December 2011]

Hi Gill, Thanks for your quaestion. Sadly, as you have found, most mini and micro stereo systems do not have a dedicated turntable input. A turntable requires a special input, that has a pre-amplifier with R.I.A.A. equalisation. Some stereo systems will have a standard line-level "AUX" input than can be used to connect a device such as an mp3 player, DVD player or cassette deck etc. This type of input is not suitable for connecting a turntable directly however, but using an additional external turntable preamplifier, such as the NAD PP2 or a Pro-ject Phono Box for example, will allow the use of a turntable with a standard line leve auxilary input.

Unfortunately the Yamaha CRX-330 system has no auxilary inputs whatsoever - so you'll need a new system. I recently researched some micro hi-fi systems and was very impressed with the Denon DM38DAB. Along with FM and DAB radio tuners and CD player, the Denon system has a multitude of additional inputs: A 3.5mm stereo input jack on the front panel for connecting any MP3 player or other device; a USB port for iPod docking and control; a tape deck loop consisting of four phono sockets on the rear panel; a standard line level auxilary input consisting of a stereo pair of Phono sockets on the rear panel. It sounded very good indeed and appears to be good value for money. This could be just the system you need.

You will still need a turntable preamplifier (e.g. NAD PP2 or a Pro-ject Phono Box) to connect your turntable to the system via the rear auxilary input. Please visit a specialst hi-fi dealer such as Superfi, Sevenoaks Sound and Vision, Audio T, Sight and Sound or Richer Sounds to have a look and a listen. I am sure that such a system will suit you very well indeed. Do let me know how you get on! Mike.

Great, thanks so much for your help!

Kind regards, Gill




Good Evening Mike, I have just read your web page with interest as I have just acquired a Palstar PS30 power supply. However it was supplied without a user manual and I have been trawling the internet looking for details. I wondered whether it would be possible for you to scan and email me a copy. I would willingly contribute to any scanning/printing costs etc.

With kind regards, Chris, M6XJP

[November 2011]

Dear Chris, Many thanks for your email, nice to hear from you. Do you have a specific question about the PSU? I do indeed have a printed copy of the manual filed away, so I have added it to the website for you here.
Best wishes, Mike, M0MTJ


Good Afternoon Mike, Thank you so much, that was most kind of you. In response to your earlier email the reason for my enquiry was that, unlike the common perception that males just connect things up and then read the manuals at their leisure(if at all), I value my gear and wanted to make sure I didn’t do anything detrimental. I know it’s only a simple PSU but better safe than sorry.

I have to congratulate you on your website – a mine of really useful information – which I have tagged for future reference. I am also extremely envious of your obvious technical ability. I have to say that since obtaining my licence in March last year (a present to myself on achieving pensionable age!) I have found nothing but friendship and endless help from the Amateur fraternity. Your kind assistance on this matter is just further proof. Many thanks once again.

Kind Regards, Chris, M6XJP

[November 2011]

Hello Chris, Thanks for your reply. It's a pleasure to help you. I hope that the information was useful. You are quite right - it is always good to read the manual before connecting and using new equipment. I usually try to download the manual and read up on the basics before even buying something new.

Thanks for the compliments on the website. I always hope it's useful to someone, even if it's only the host of useful links! I am a relative newcomer to amateur radio too, but I have spent many years with an interest in radio, SWL and things of an electronic nature. I must admit that I am no expert, there are very many more operators on the bands with vastly greater experience than I have, and a more detailed technical ability - but thank you for your compliments! I keep trying!

I hope that your experiences in amateur radio continue to be good ones. I do always try to be of help where I can, and it's rewarding when that is possible. I must say that I (like everyone I suppose) feel that there is an an opportunity to learn something new every day!  Find out more about Amateur Radio here!

Best wishes, Mike.



Dear Mike, I wanted to send out a quick thank you letter in regards to your sundials page. I work at an after school program and your resources have been very helpful, we've been making sundials the past few days.

The students and I have been working on creating a section of our website which has fun links for kids to use at home.  I used a few of your links in there for the kids and their parents to check out, so thanks!

  Hi Mike, I am thinking about beginning as a licensed radio amateur. What is the minimum equipment that I must buy? I like a Yaesu FT-897d. I'd appreciate your comments very much. Thanks in advance

Regards, Fernando Osorio
[October 2011]

Many thanks for your email Fernando. The FT-897D is an excellent transceiver. It is very versatile because it is a nice size to use as a base station radio, but it is also transportable so can be used mobile ( /M) or even portable ( /P).

What else do you need? Well.....You will need to study for your licensing exams, so a good study book from you local amateur radio society is an absolute necessity.

Once you have passed your exam and been granted your licence and obtained your call-sign from the licensing authority you will need some other things: A power supply to power the radio. A 25 amp PSU is common for this radio. You will also need an antenna or antennas for H.F. work (1.8 to 29 MHz) and an antenna for 2metre and 70cms (144 and 430 MHz). Perhaps later you might consider another antenna for 6 metres (50 MHz). For H.F. operations you will need an Antenna Matching Unit (often referred to as an ATU) to match the varying impedance of the antenna to the 50 Ohm impedance required by the  transceiver.  Many ATU's have built in VSWR and Power Meters, but if not you will need a separate, external VSWR / Power Meter. A dummy load is pretty much essential too.

You'll also need basic tools, for example: Digital multimeter (DMM), 50W Soldering iron, screwdrivers, spanners, pliers, ruler, tape measure, calculator etc. You can read more here>. I hope that helps you. Good luck with your exam and licence.

Hi there, I have been trying (unsuccessfully for a while now) to track down a copy of the instruction manual for a Lowe HF-125 receiver.  It has just come back to me after spending the last 15 plus years in a loft and I want to fire it up again.  Any suggestions as to where I might get my hands on a copy of the manual, would be much appreciated.

Best wishes,  Tony [August 2011]

Hi Tony, Thanks for your email. I have sent you a copy of the HF125 manual as an attachment. Hope that helps and that you enjoy using your classic Lowe HF receiver again!

Wow Mike, that's brilliant. Thank you so much.

Best wishes, Tony




Hi Mike, I chanced on your site while reading up on DAB radio as my wife and I just bought a Sony DAB, I noticed your Siamese Sienna, as we have 7 Siamese and 2 moggies. We also show some of our Siamese cats. You may like to take a look at my wife's website to see all our cats! The URL is www.lizs-lot.co.uk  Maybe if you deem it worthy you would consider putting a link to it? if you do i will make sure a link is put on it back to your website.

Graham Ellis (DAB radio novice and Siamese owner & lover!)
(August 2011)

Hi Graham, Thanks for your email. We've have had a look at you website - it's excellent. What a wonderful collection of cats you have!! I will certainly put a link to it from the cats page and links page. Thanks again, Mike.



  Hi, I stumbled upon your website today and I found it endlessly interesting, it is a real treasure trove of information. When I get enough time I feel I may have to try and build one of the crystal sets, and if it's easy enough try and get my Scouts to complete some. I am going to have to book mark your page and keep coming back to it as it is very interesting.

I am a bit of a radio fan myself, I volunteer at Kingstown Radio which is Hospital Radio for Hull & East Yorkshire. Thanks for putting so much time into your site, I have included a link on my homepage http://www.richardellarby.co.uk

Yours, Richard Ellarby.

Hi Richard, Thank you very much for your email - glad you found our site! A crystal set is always a fascinating project and could be a very good Scouts project. Thanks for the link! Best wishes, Mike.



  Hi Mike, That Everyday Electronics ZN414 matchbox radio brings back memories.  I made exactly the same one in the long hot summer of '76.  I first used it on a coach trip from Surrey to Devon to join my parents on holiday.  I'd stayed behind to take my driving test.  Oh to be 17 again (but with the knowledge I have now ;¬)  Andy.

Hi Mike, I would like to congratulate you and thank you for your uploads of BRMB recordings from 80s and 90s. I was particularly interested in the George Gavin and Tom Ross football phone ins. I was a keen listener and never missed a show and never thought that I would hear them again until I came across your website. 

Kind Regards, Bobby. (June 2011)

Hi Bobby, Thank you for your kind comments - glad you enjoyed the BRMB archives! You can find the BRMB audio here>



  Hi Mike,  Congratulations on a great web site. I remember building one of the Ladybird book circuits back in 1975 and was quite pleased with the result. This was at a time when transistors seemed expensive. Nowadays, I have amassed quite a stock of radio components, the result of being an electronics hoarder.  I am looking at building the Triple T  HAC receiver and noticed your nicely finished radio.

Best Regards, Symon McCabe. (May 2011)

Hello Mike, I’ve tracked you down because I would love to know what happened to Martin Dean. Martin had a great late night show on Radio 210, playing new age and jazz funk. I recorded one of his shows which I still have on cassette and still listen to Even with access to internet radio stations around the world, I have not yet found a programme to better it Any news of Martin, or any other recordings of his programmes (this is a long shot) would be much appreciated

Many thanks, Terry Bailey, Basingstoke, Hants. (May 2011)

Hi Terry, Thanks for your email. Julian Watson is an enthusiast in that area and knows a great deal about Radio 210 and GWR (WR) so I have passed your details on to him and asked question. He replied:

"Hi Mike, Yes Deano did a great soul show. I do have a few clips from his shows post 102.9 going on air, so I can help Terry a little in this respect. As for what happened to Martin, he was always a keen computer man and the last I heard he had gone back to working with computers after he left 210. This was some time ago. Hope this helps. Julian"

Sorry, no cat pictures or personal stuff except my tech stuff, but I do have a wonderful Manx cat. She's black and somebody named her Pepper. She is quite verbal sometimes. Her meow is like that of a chain-smoking lounge singer... really rough and somewhat annoying. I've been trying to get her to learn a sweeter meow, but so far no luck. I have a picture of her here >.

Mike, I was passed your link from one of our club members and you had such a section on the pop pirates I thought this might interest you:

Eric G3PGM (now Silent Key) mentioned some thing in a QSO some years ago when he was alive! That he had been involved in something illegal and it had nearly cost him is marriage and his life. He asked me to scan some images and then he let on about his past writing this article which he had kept secret from club members but as time gone by he felt it would be of interest.

Eric would not print the part on the 2 women that got married while he was at sea but the News of the World printed it and his wife was not happy. At the end of the article you will see that he left a week early and his replacement was then drowned in the boating incident. Last year the sister contacted me for more information as she lives local in Henley on Thames, so I was able to point her in some directions but time has moved on and the information that was available is getting lost.

I’ve attached it for your reading and you are most welcome to use it or link to it. Read Eric's article here>

Hi Min, Thank you very much for your email and excellent aricle which you can read here>



Hi, I've been reading your excellent history of radio broadcasting. I feel, however, that I must take issue with you on one point. You state that "INR1" was advertised as a non-pop licence, and was awarded to Classic FM " I  believe that this is incorrect because, if my memory serves me right, the licence was awarded to Showtime Radio, which was to broadcast from studios in Milton Keynes. The problem was, that the promised financial backing failed to materialise and the licence was handed back. It was then that the 2nd choice, Classic FM, was given the opportunity to become the first national commercial radio station.

During Classic FMs test transmissions they broadcast from the Peterborough transmitter as Radio 101.6 - "One O One Point Six" - and I believe the first voice on 101.9 was that of Nick Bailey. Other broadcasters included Petroc Trelawney and Henry Kelly.

I hope you are not offended by my contacting you like this and may I compliment you on your history site.

Kind regards, Michael B Cox (April 2011)

Hi Michael, Thanks for your email. I'd forgotten that little bit of detail, but I think that you are right.

I did remember that Showtime Radio was initially in the running, but dropped out due to financial trouble of some kind. I cannot remember if they actually got to the stage of winning the licence then handing it back, or if the licence went to Classic FM (due to the financial doubts over Showtime) before the actual licence award was made.

I do feel sure that the Radio Authority advertised INR1 on the basis that it would be a non-pop service - i.e. not the chart music oriented radio station. Showtime Radio would, I feel, have also fitted that description - as would a jazz, country or folk music based station I suppose.

Perhaps I'll have to research these finer points.

The pre-launch marketing tests for Classic FM were called "Radio 1 - 0 - 1 point 6"

These programmes were broadcasts from a series of 'RSL' transmitters dotted around the country, all broadcasting a simulcast of "Radio 101.6" distributed nationally (via satellite IIRC). The transmitters would all have been low power - perhaps 25 watts - to conform with the RSL restrictions of low power, fairly low aerial height and 28 day licence length.

GWR was one of the main backers of the Classic FM venture and at that time GWR had just bought Mercia Sound in Coventry. The city of Coventry was one of the locations for a "Radio 101.6" transmitter and perhaps the fact the GWR owned Mercia Sound meant that the city was part of the reason for this. I had assumed that they sited the RSL transmitting antenna on the Mercia Sound building in Coventry - but I never had this confirmed.

The purpose of "Radio 101.6" was for marketing and to test the 'sound', play-list and the content of Classic FM, when it launched.

Nicholas Tresillian was regularly heard presenting on "Radio 101.6" - I believe that he was the founding Chairman of the radio station WR/GWR.

Later, of course, work on installing the first stage of the main VHF/FM transmitter network began. First on air for test transmissions was Wrotham in Kent. Later, as you note, the main high power transmitter at Peterborough using 101.9 MHz was installed.

Thanks again. Cheers, Mike!

Hi Mike, Great memories of Mercia Sound from your site (it was the station that inspired me into radio), especially seeing “Private Life, Public Image” on which my father was featured one week. I'm now a part time presenter. I did have my own evening show on permanent station Corby Radio, have also presented on Ashby Radio, Whittle FM, & Radio Lutterworth, all of which were RSL. I now have a show Global Dancefloor which is broadcast by 58 stations worldwide, all the fault of Mercia Sound in 1980!  www.globaldancefloor.co.uk

Keep up the good work and memories.

Thanks, Julian Little.   www.domustiles.com  (March 2011)



Hi, I was browsing trying to find someone who does repairs to Lowe Receivers and saw that you had contact with a Gary Elesmore who said that he did. Do you know if he still does this work, I would be most grateful if you could advise. I do like the website excellent info. Best regards Peter Cartwright. (March 2011)



Hi Mike, I don’t know if you’re interested in any of the history, but I’d like to think I was one the main facilitators of CB in the UK from 79 to legalisation. If not the first, were in the first 2 or 3 major importers (and undoubtedly the largest), we supported CB Radio Magazine from when Miles first started it up, advertising in every copy from Issue #1 (I still have them all somewhere).

I also wrote the infamous ‘CB Song’ in 1980 with Spatz Melzer that was promoted on 10/4 day in 1980, and is still selling well on eBay.

The early pre-legalisation days were surreal in many ways, with some huge personalities, most of whom I’ve lost touch with. It’s interesting to see that some of the equipment suppliers on your links page were my customers in those days, over 30 years ago.

Anyhow, if there’s anything you’d like to know, drop me a line.

Hi Andy, Thanks for sharing your early CB memories. Excellent!  More about Citizens Band Radio here>



  Hello Mike, What a great site I compliment you on all your hard work. I remember BRMB back in 1974 when I lived in Stratford upon Avon. In fact I won a record and tee shirt!! I also did a lot of charity work for the blind driving a narrow boat up the cut to give the people a day out; I heard the appeal on BRMB.

I write to ask if I can put a link onto our club web site, the Barry Amateur Radio Society  http://www.bars.btik.com

Again my thanks and appreciation for a very informative site.

73  Glyn GW0ANA, Chairman, B.A.R.S. [March 2011]

Hi Glyn. Very many thanks for your email. Those far off days of BRMB in the seventies were indeed great times! We're only too happy to add a link to your club site at http://www.bars.btik.com.



  Hi Mike, I have just stumbled across the article on community radio. Here are a couple of pictures to go with the text. I am the guy standing on the left and the guy on the right is from BBC Bristol  - sorry it was a long time ago! Chris Hibbert [March 2011]

Thanks Chris, that's much appreciated. See the article and Chris' photographs here: Community Radio 3



  Hi Mike, Please can you put me in touch with a someone from whom I can order a permeanant crystal (diode) for my 1922 Crystal set. Many thanks for your help. Bob Lewis. [March 2011]

Hi Bob, I imagine that it would be quite difficult to source the original detector for this radio, but you may find something similar that would do the job. I have provided some company names and links below that may be able to help or point you in the right direction. If you cannot find a suitable detector immediately you could connect a modern germanium diode into the circuit. Diode type OA47 or 1N34 would work very well indeed, but you could also try an OA80, OA81, OA90 or OA91 if you have one. Here are the contact details that may be able to help with rare and vintage components:

J BIRKETT Radio Components - 25 THE STRAIT, LINCOLN, LN2 1JD. Telephone (uk) 01522 520767 
Birkett's often have rare and so called 'surplus' components in stock, particularly surplus air-spaced tuning capacitors.

6V6 - Electronic Nostalgia and Vintage Components. Visit http://www.6v6.co.uk

VINTAGE COMPONENTS - Another possible source of components, TRF valve radio kits and (most excitingly) low power AM Medium Wave transmitters for listeners and experimenters who no longer have a local AM broadcast station within range: http://www.vcomp.co.uk/index.htm

Here are some other interesting links for you: http://makearadio.com/crystal/17.php   http://www.midnightscience.com/kits.html#kit4D

Best wishes, Mike. MDS975

Many thanks for your helpful reply to my enquiry. I am not very proficient with the computer. I will ring the company in Lincoln.   My receiver is in good condition, it stands next to a 1935 Ecko radio, the round type. Goodbye for the moment. Bob Lewis.
[March 2011]



  Mike, I just thought I'd drop a line to say how pleased I am to have found your site.  I stumbled across it yesterday via the usual convoluted route - Town Hall concert in Leeds, listened to Purcell's Abdelazar suite, said to my companion that it used to be the intro music to a BBC radio service, couldn't remember what that was called, hit the web and bingo, found your site and the name Network Three.

I've just dipped in to Vinyl Heaven.  I have a load of LPs and inherited a Technics SL2000 deck from my dad about 20 years ago.  It still goes well although I've had difficulty sourcing styli and decent record cleaning kit.  When I've got a minute (!) I'll use the contacts on your site to get that sorted.  I inherited a pile of LPs from him too as he was a hi-fi fanatic but haven't managed to play them yet.

I intend to read your history of UK radio as I heard so much about the early days from my dad, who was building his own sets in the early 1920s.  I've 2 copies of the Radio Times from 1924, before it became the Corporation, and they give a fascinating insight into what wireless was like then. Thanks so much for putting your site together.  Keep up the good work.

Regards, Pete Shilson.
(February 2011)

Dear Pete,

Thank you so much for your extremely kind email, it's really good to hear from you. I am glad that my brief radio history was of some help! It is just a brief account really and as such I included links to some other resources that provide greater insight and detail which I hope will prove fruitful for you.

As for vinyl records,  I still enjoy the medium very much. I wish I had the time and money and, particularly space, to invest in some classic, vintage hi-fi components from years gone by. I often look at photographs of hi-fi separates from the 1970's and 1980's and wish that I could collect and accommodate just a few of them! I still love the look and appeal of some of the equipment of that era from Rotel, JVC, Sony, Technics, NAD, Sansui and Akai - to name a few. I am really glad that I have the Technics turntable, that really is something I'd never change. What a piece of equipment!

I haven't used an SL2000, but I am certain that you'll spend endless happy hours with it. I don't know what sort of cartridge would be fitted to it, but assuming that the arm has a standard 1/2" headshell, then any good modern replacement cartridge could be fitted to it, which should make future stylus replacement a lot easier. The arm may also allow for a new headshell to be fitted, if necessary.

Look after those 1920's Radio Times!! Wow - fascinating indeed!  Happy listening - Mike.



  Mike, Great site you have an excellent page on aerials, I'm looking to build aerials for hf and 2m now that we have moved house and have the space again. After viewing your pages I'm thinking fan dipole for the 20-10 metre bands, inverted trapped L for 160-40 metre bands and either a dipole or halo for the  2 metre band.

More interesting for me was too see your pages about Mercia Sound as the house we have just bought and moved into has been the family home of Stuart Linnell for the last eight years or so. I too remember the test transmissions and early days of the station here in Coventry, although my love of radio stems more from building a crystal (germanium diode) radio and listening to BBC's Radio 4 and 2 on a portable transistor radio my grandad gave me and then CB radio (handles Microchip and FM Deviator) here in Coventry from 1983/4 on and off to 2000, whilst a Telecommunications Technician Apprentice at GEC Telecommunications taking my RAE in 1988 at Coventry Technical College with the encouragement of a CB friend (and Elmer), (Mobile Mike, G4RCS). Anyway just wanted to say thanks for the info available on your site.

Best regards, Andrew Brookes (operator of amateur radio station G7KXM) (February 2011)

Hi Andrew, Thanks for your email. I have not experimented with a fan dipole personally, but I know someone who has and the results did seem very impressive. The inverted L should also be a very good choice. A dipole for 2m keeps things nice and simple for an effective home-brew project. As for Mercia Sound, it's fascinating to read that you have bought your house from Stuart Linnell. He's a rather interesting character I feel. He was there in the great and glorious days of Mercia Sound in the 1980's, but was also at the helm as the station went down market in the 1990's finding itself where it is today, at the lowest common denominator. I suppose we cannot really blame him entirely, the policy must have been set by the station's corporate owners and encourged / caused by the policies of the regulators The Radio Authority and its successor Ofcom. There must have also been some rocky times in more recent years with the Laser Broadcasting failure which affected Sunshine Radio in Hereford I beleive.

However it is now really pleasing to see Stuart Linnell doing what he does best, that is broadcasting at BBC Radio Northampton. Excellent!

As you may have read, my fascination with radio also stems from crystal sets and TRF radio experiments as a lad in the 1970's. On those radios I listened to Radio 2 on 1500m and sometimes Luxembourg on 208m if I was lucky! I also dabbled with CB and gained an amateur radio licence, but I am really still a listener day to day, while doing some occasional experiments and construction.

Thanks for your memories which are fascinating. Kind Regards, Mike.       Mercia Sound pages here>               Amateur Radio pages here>



Hi Mike

I was very interested to see the Radio Vicomte mast photos on your website. I visited the studio some time ago and was shown around the small house. The station manager pointed out the small dish on the building which transmits the signal to the main transmitter on the hill through a gap in the trees and buildings. The receiving dish is visible in your photos. I'm going there next week and I would be happy to photograph the dish at the studio if you would like. The station transmits a rather bizarre mixture of music and is a very strong signal at my house in Vegennes.

Regards, Chris G4RBR (February 2011)

Hi Chris, Thank you very much for your kind email. The photographs were taken by our friend Martin Watkins when he visited that area of France. I'd certainly be very grateful for any new photographs of the TX site, studio building or dishes that you can take. I have not heard the radio station, but it does sound like a happy mixture!!  The photographs of the Radio Vicomte transmitter site can be seen here >

Thanks again - very much, and I look forward to some new photo's! Regards, Mike.



Good day Mike. I stumbled across your website quite by luck while surfing for shortwave links. You certainly have a very extensive website! I've just spent a couple of hours, looking and reading, and have barely scratched the surface. I am particularily interested in your amateur radio activities/equipment/history etc. I've been an enthusiastic SWL'r [Short Wave Listener] for over 50 years and I love anything to do with radio, shortwave, antennas, ham gear. Never got my amateur licence but I do like to listen to the world. I use a Kenwood R-5000 receiver connected to a simple longwire antenna that is end fed with coax. Back-up is a Radio Shack DX-394. Both receivers are good performers.

I received a SWL'r certificate recently from SWARL and I joined eQSL.cc just 2 days ago. My sign is VE3022SWL. We live here in Orangeville, Ontario, Canada and this town is about 1 hour NW of Toronto. I looked you up on QRZ.com which I joined also, although I have no content posted there yet--something to work on!

I've included an attachment in this email--it's just a pic of my new SWL certificate. Back to your website now because it's only 19:37 hours here.

Nice to meet you and 73 de Doug Stevens in Canada! (February 2011)

VE3022SWL - Doug Stevens SWL Certificate


Hello Doug,  Thank you very much for your email, it's really good to 'hear' from you. The Kenwood is certainly a nice receiver. I not used the DX-394, but I do have a Realistic (Radio Shack) scanner which has always been very good,  so I can imagine that the DX-394 is very good too. I have always enjoyed experimenting with aerials and other simple accessory circuits and simple receivers too. Thanks for your certificate (above).

Jules and I have been to Canada twice and thoroughly enjoyed ourselves - it's a truly wonderful country. One of our trips was to Toronto. We did not pass by Orangeville unfortunately, but we did get driven past Peterborough on the way to the excellent dogsled centre at Winterdance in the Haliburton mountains. We were also taken past Burlington, Hamilton and Saint Catherines on the way to Niagara and Niagara on the Lake. As for radio in that area - I really enjoyed the CBC along with AM640 Talk Radio Toronto, Newstalk 1010 CFRB and 610 CKTB. 

While we were on holiday in the Mediterranean last year we met a couple more  great Canadians - Frank and Sue. They beckoned us into a lovely little cafe bar in Turkey as we were walking past checking out the menus. We did not know them at the time, but Frank called out "The beer's great in here!", so we went in and had a good old laugh. - So it's nice to meet another Canadian via the email and internet right here!! Thanks again for your email. Give our regards to wonderful Canada.

Hello Mike, I came across your website on the net and I was wondering if there is a possibility for a link exchange. I sell CB's and related equipment mainly for truckers and 4x4 users. I am a licensed amateur as well and will be selling amateur stuff on the site once everything else is on. http://www.truckersnet.org.uk/index.asp  Kind Regards, Toby Dunne. (February 2011)

Hi Toby, Thanks for the information. we've added a link on the CB Radio Links Page here>




Very nice web site.  Excellent graphics.  Especially like the page on capacitor setups for loop antenna tuners.
Ed Ruff, Kennewick, Washington,  USA  (January 2011)

Hi Ed, Thanks for your email and particularly for your kind comments. I do try to do my best to make things clear, so I am glad that you found the medium wave loop antenna information helpful. Thanks again, Mike.



Hello, I'm a big music and radio fan. Ssadly radio and music has changed but I still love listening to old music on the radio and I'm trying to find any memorabilia from Red Rose Radio before it became Rock FM, around the time Red Rose Gold started and all the presenters that were on at that particular time. Any information about the station and where a lot of the presenters moved on to would be gratefully received. Many thanks, Mick. (January 2010)

Hi Mick, Thank you very much indeed for your email. You are quite correct, music and radio has changed a great deal. Sadly commercial radio has changed a great deal for the worse and most of it is utterly dire these days. Regrettably the only recordings of Red Rose Radio from the 1980's are those that are already on the website, which you have probably already found. I wish there was more from that era. Hopefully you may be able to unearth some more audio of Red Rose somewhere - so Good Luck!



Hi, Thanks for posting BRMB's Sleeping Beauty... I was listening to this on a very poor recording I had made. That made me search for this and I found your site... Great Posting! Gez Bos. (December 2010)

Thanks for your email and for letting us know that you enjoyed BRMB's hilarious version of Sleeping Beauty. BRMB's radio-pantomime Humbug is on here too, so we hope that you enjoy that too!



Good evening Mike, Greetings  from the tropical island of the Philippines, I'm Eduardo Bolivar Simbol, thanks for bringing back memories of the Ladybird book on Radio, back in the early 1970's.  I was in the sixth grade then and I bought a brand new copy [of Making A Transistor Radio] for  2 pesos and 50 centavos from one of the  variety/toy stores here in our town of San Juan, Rizal. I vividly remember the beautiful illustrations, especially the colorful resistors and the crystal earphones. I was able to build a crystal set, but I was not  successful in finishing this radio project due to my meager allowance then..........and  the wonderful scent of the pages of the Ladybird books from the UK, I  thought to myself,  Britain, London, the UK, smells so good !!!.

I also bought  from that store, Matchbox toys made by Lesney of England (Jumbo crane, bulldozers, Lotus racing cars) and the small carton boxes have the same wonderful scent. I am a shortwave listener and back then and I got Radio Nederlands (they sent radio schematic diagrams by mail), Swiss Radio International (they had a contest where the prize was a Rolex watch ), Radyo Peking (in Filipino), BBC World Service and VOA - The Voice of America. 

Thanks again and  Best regards  

Eddie B. Simbol (November 2010)

Hi Eddie, Thanks for all those wonderful memories of Matchbox models, transistor radios and great shortwave radio stations!!

Best wishes to you! Regards, Mike.  See the crystal set and three transistor radio projects here >



Hi, My Name is Roy Hart I have been trading in CB’s here in Kidderminster since before they were made legal back in 81. I have established a website. Would it be possible to be included on you CB Radio shop’s list?  Our website iswww.cbradioshop.co.uk

Kind regards, Roy, CB Radio Shop, Kidderminster (November 2010)

Hi Roy, Thanks for your email, it is a great pleasure to add a link to your shop's website to our CB Radio pages. Thanks again, Mike.


That is wonderful, thank you very much. 73’s & 88’s -  Roy,  G1UXK



With regard to article by Rev G C Dobbs; Three Transistor RadioI have a small supply of OC45 & OC71 transistors which I am happy to share should anyone wish to build this excellent radio. Regards Doug Wallace. (November 2010)

Hi Douglas, Thank you for your email. I have added your message to the Ladybird transistor radio page.

Thank you for your very kind offer Dennis. Best wishes, Mike.



Hi Mike. Hope you are well, I am striving to set my [Technics Sl-1200] deck up for the best sound possible, not that it sounds poor at all. I wonder if you could give me some advice on the arm set up height please?

The Audio Technica cartridge I have, which [we] mentioned...in previous emails has a height of 28mm and should track at a 20 degree angle according to the specifications that came with it. The technics manual, in the setting up section for the arm height adjustment, only mentions adjusting height for cartridges up to number 6 on the dial for cartidges up to 20mm.  I have also read on the net that the front and rear of the tonearm should be level which would totally throw out the technics setting up instructions? Any advice greatly appreciated.

Many thanks, Mick. (October 2010)

Hi Mick, I don't know if you are using an At120 or an AT440, but both are similar. For my own AT120E I have the arm height setting on the SL-1210 set at about 3. This puts the cartridge height at about 18mm, this works very well for me.

Do also use the cartridge gauge that Technics supply with the SL-1200 to make sure that the cartridge is positioned correctly in the headshell. That should initially be good enough to set proper alignment and tracking.

However, as I mentioned, I also used a more specialist alignment protractor to ensure absolute accuracy. A word of caution though, this is a rather tedious and time consuming job to do accurately. So just use the Technics guide first of all and set the arm height adjuster to 3.

I hope that helps. Best wishes, Mike  -  See our Vinyl Pages here >

Hi Mike, My cartridge is an AT120E. Thanks again for the valuable advice. Much appreciated.
Mick. (October 2010)

Glad to help, Mike.



Hi Mike, I have recently reacquainted myself with your site,and find the radio section particularly interesting. I run a group on Facebook for the former fort based offshore station Radio City. So far it has over 80 members. Couldn't see any link from your site to Facebook, so I assume you have no page or group affiliated?

I did however post a link for MDS975 to my profile page and have received favorable comments from those who have seen it. Can I be cheeky and ask if you would consider putting a link for the Radio City group on your pirate radio page? The link is as follows :-

Hi Dennis, Thanks for your email. You're correct, I am not on Facebook, but it is a great pleasure to adda link to own Radio City Facebook page to our Radio Links pages. Good luck with your website, best wishes, Mike.


Thanks Mike, It's a passion with me! Those boys worked hard to keep us entertained, in no little discomfort and at times personal danger! I feel the least I can do is honour them and it's great that so many people feel the same way! Thank you so much for your link,it all helps people realize we are here!
Regards Dennis.



Hi - Norman Wheatley here, Nice to get a mention among all the luminaries of BRMB, but I did a little more than " Romantica". I presented "Late On" from October 1981 until February 1985, four hours a night, five nights a week!

Cheers,
Norman. (September 2010)

Thanks Norman - the great Warm 'n' Neatly - excellent to hear from you! You are quite right to point that out and we've added the info' to the BRMB pages.



  Further to a previous query regarding turntable reproduction Adrian writes: "Hi again Mike, I have just been looking at your website. I really like it. Your approach to the joys of vinyl sounds very much on my wavelength. Just great!! I actually would have got back to you sooner about my hi fi glitch, but I lost your e mail address. Glad I found it again.

If someone is good enough to give you some time and finishes with "let me know how you got on" and you don't, it seems like you are not bothered. That's why I took so long to get back to you...I shall return to your site later on, and have a good study of it. Nice pics of Canada.

Thank you Adrian, gald the advice helped!



  Hey, I was talking to my wife about having built the Ladybird set when I was a kid. Wondered whether the book was still in Dad's Loft.Tthen found it on Amazon. anywhere from £8.98 to about £100 more! I found your site by Googling Mullard OC71 (I forgot about the OC45 RF transistor though.)
 
I built the set when I was in top year juniors when I was 10, so that would have been in 1973. I had to adapt slightly in that we got a miniature tuning capacitor instead of the big one. It worked fine and once built the main station was radio Caroline broadcasting from the North Sea which introduced me to music other than top 40. A few months later my aunt bought a small transistor set for my birthday which got more stations but didn't sound as good!
 
Shortly after building the Ladybird project I ordered an H.A.C. 1 valve regen' set with short wave coil and a very dim heater winding in a tube which worked off a 90V H.T. battery and and cycle lamp battery for the L.T. I put a reduction drive on the tuning capacitor and upset a lot of Hams by tuning their SSB signals by setting the regeneration right. This caused a lot of feedback on their channel; hey I didn't know, I was 11!  I also managed to pick up Radio Australia as well as Radio Moscow, Voice of America etc.
 
The most interesting thing was the resistance broadcasts from Cambodia (Kampuchea as it was then) long before we saw anything about the Pohl Pott regime in the UK media.
 
I still have the HAC set buried away somewhere, but I think the ladybird set was broken up for other experiments!!
 
Regards,  Nick James.

  Hello Mike, I Just bumped into your website. Somehow!

Nice job.  Lots of stuff and ... Lots of links to airchecks, my favorite.  Thanks for all that. I'm just learning about the European version of what I experienced stateside in Wisconsin. Check out http://www.reelradio.com if you haven't already.

Mark, Thank you for your kind words and for the website recommendation which we will enjoy checking out!



  Hi Mike, This is the BEST CB radio website on the web! I have been CB RADIO operating since 1980 here in Donegal Ireland, then CB was very much alive and almost everyone was talking! The 40channels were quite crowded. It is Real Radio and completely free of licence and operating costs! As I have been a Short Wave Listener since 1960, CB Radio was a godsend to those of us who love Radio!

Your Site is very informative and interesting for anyone to catch the CB radio bug! I do know they are groups of CB breakers around most of the large cities in the u.k. as I was from Glasgow, Scotland then. Do Keep CB Radio ALIVE! It's a great free- to- air radio system!

Best Regards, Frank Fleming, Foxtrot 310, Ballyshannon, Donegal, Ireland.  [August 2010]

Hi Frank, Thanks very much for your email, it really is greatly appreciated. I am glad that you like the CB pages. I hope that they continue to do some good - radio is such a fascinating subject!

Thanks again, 73, Mike.


  Mike, Thanks so much for such an interesting website.  There is a new ham in Pensacola and I'm directing him to your site for some good ideas about how to set up his antenna farm.  One of the things I've enjoyed most about 40+ years in Amateur Radio is the ability to visit with hams around the world.
 
The "new" ham I'm working with is excited about his new radio hobby and wants to do "everything" immediately!  Obviously, the "learning" part of ham radio is probably the best part but it takes time to develop basic radio knowledge and skills. I look forward to letting you know about the new ham's progress.  I was especially impressed with your inverted L antenna with coil.

Hi Steve,

Many thanks for your email, it's great to hear from you. I'm glad that you have found my pages interesting and that they may prove helpful to your friend in Pensacola. As you'll already know the antenna is probably the most important part of the station, so it's quite a challenge trying to decide what the most effective solution will be.

I suppose some of the simple key factors are to get as much wire in the air as high as possible and feed it using the lowest loss line as possible. Tuned dipoles and twin feeder are a great low loss, high efficiency, low cost starting point - more effective than some commercial antennas costing hundreds of dollars, yet only costing, perhaps, $10.

As I have found out, there are some interesting wide band antenna designs, but you may lose 10dB or more of radiated power - so while your transmitter may be producing 100 watts output, your station is only radiating 10 watts or less!  Lots to think about for your new ham friend. I am sure that there are going to be lots of fascinating antenna experiments coming along!  More on the Amateur Radio pages here.

Please feel free to pass along my comments and may I wish you and your new ham friend the very best of best wishes from England.

73, Mike, M0MTJ



  Dear Mike,  May I compliment you on your www.mds975.co.uk site which, every time I visit, seems to provide new interest and new things to discover!
 
In March I launched a site featuring the work of Gilbert Davey, the writer on radio and electronics for young people, who introduced several generations of youngsters to radio as a hobby or career, and about whom there has been little to find on the internet.  My site deals in depth with his "Beginner's One-valve Set", and in particular attempts to fill the information gap about one famous version of this, the BBC Studio ‘E’ receiver, which aroused extraordinary interest when its construction was serialised on BBC Children's Television in 1957.  There is a sketch of Davey from published sources, and a reading list for finding his radio designs.  I have tried to include something to appeal to anyone, whether techie or not.
 
My site can be found at http://www.thestudioeonevalveradio.org.uk  (You will find a link to mds975 already added on my Links page).
 
Please take a look, and feel free to add a link if it would be of interest to your visitors.  If you decide to do so, please use the attached JPG logo image rather than the one from my pages (which has a transparent background and does not look its best on other background colours).  Please also let me know if you add a link.
 
With best regards, and congratulations again on mds975,

Dear Les, Thank you very much for you email and alerting me to your own utterly marvellous website. I have have added  a link from my Radio Links page for you. I hope other enjoy the site as much as I have looking through it. The Studio E is a really interesting project and so well executed in your own implementation. Very impressive!

Thank you again, Mike


 
  Hi Mike,   I have just spent the last half hour or so reading your website, especially your antenna pages.
 
I would like to take this opportunity to thank you for taking the time to place all the info and your ideas for antennas for samll gardens.  Not surprisingly I have almost the same problems that you have and finding sensible information regarding antennas for small gardens that is written in a way in which it can be understood without a degree in physics is 'like trying to find Rocking Horse droppings'.
 
I have been licensed now for just over two years, in fact I had the dubious pleasure of sitting my Advanced paper on Wednesday, What a delight that was...Not!!
 
Until now, I haven't done any HF work purely and simply because setting up a suitable antenna in a limited space, in fact finding our about a suitable one has been extrememly difficult. All my radio work has been mobile on 2m & 70cm using a wide variety of repeaters. I am absolutely delighted that your ideas and the antennas that you have used will fit in nicely in the location that I am in.  In fact, I'm already getting stuff together and working out the designs and the calculations on paper.
 
Hopefully, at some stage in the not too distant future I will manage to have a QSO with you, I look forward to that.

Thank you so much, this has been a lift to may day. Hope to speak to you soon.
 
Kind Regards,  Rob 2E0RHM  Cheshire
[April 2010]

Dear Rob, Thank you for your email. It is really good to know that my pages have been of some help. Trying to fit a worthwhile HF antenna into a small garden really did seem to be a challenge that was impossible to overcome when I first started out! Hopefully you'll find something that works satisfactorily for you.Wishing you well with your antenna projects and good luck with your exam results. Please let me know what antenna you decide to install and how you get on with it. Mike




  Good afternoon Mike, I have not visited your site for some time, and am quite impressed with the breadth of information. I run my Wireless Waffle site as ever, a radio ham also chose the same title but we are the best of friends on the net.  I have posted a link to your site on my blog and wonder if  you can reciprocate?  http://wireless-waffle.blogspot.com/

I also found your downloads of interest. It is quite worrying that analogue radio may die in 2015, I do like digital wi fi etc, but like listening to distant BBC and other locals on FM and AM - that will go with digital radio [Ofcom and the Labour government have pushed to close down the analogue AM and FM radio networks by 2015].

All the best, Keith
[April 2010]

Hi Keith, Thanks for your email. Like you I am worried about analogue radio being switched off in 2015. As I see it, the move is unnecessary - for me DAB should be used to provide additional stations - not viewed as a replacement for FM. In that way there should be less simulcasting of FM stations on DAB. In my view DAB should not be seen as a replacement for FM since the audio quality of DAB is so vastly inferior. Most stations make music sound very 'gritty' and distorted and the presenters sound like they all have throat infections!

DAB+ may go some way to solving the poor audio problem - but there again the greedy, unregulated, untrustworthy and incompetent radio groups will probably reduce bit rates even further so that DAB+ sounds just as bad as DAB does today!

If DAB+ was implemented, a passing thought did occur to me in that to make a good but little listened to station, such as BBC 6 Music, more mainstream it could be transferred to FM - say to the Radio One sub band on FM while Radio One continues exclusively on DAB+.  This move may make the case for getting a DAB+ radio much stronger and also help make the station that transferred from DAB to FM more popular. It was just a thought though, merely my own musings. In any case it looks like the BBC will scrap 6 Music!

Thanks again for your email - and for the link. I have reciprocated on the Radio Links page.


Hello Mike, I have a 40 min abridged version of Radio Acocks Green introduced by Ed Doolan and is complete as broadcast apart from the removal of a couple of records that seemed unnessasary as they were standard hits of the time. My MP3 is resampled to 32K giving a filesize of 9.586MB.

Also I have the first part of the opening broadcast of BBC Radio Birmingham in 1970. I was working at Pebble Mill at the time, it includes the news of the time plus how the station was planned. I was 19 years old when I recorded this clip, I was one of the many engineers that were involved in the new studios, we felt we were breaking new ground with a true local radio station, as indeed we were. I think the best time of my professional career in electronics was my time at Pebble Mill, I have many happy memories to look back on.

Hope you find the clip interesting, they were both recorded on cassette so quality is not so good but brings back the times when radio and tv studios were something special.

Love the site.

Best wishes,
Keith Burson
[March 2010]

Thank you Keith for generously sending the mp3 clips of Radio Acocks Green and the opening of BBC Radio Birmingham. It is most generous and kind of you. Radio Acocks Green, from 1979, can be found on the BRMB Audio Page here > and the opening of BBC Radio Birmingham in 1970 can be found on the Airwaves page here >



  Hi Mike, I came across your site while searching articles on Ladybird books and 'How to Build a transistor radio. The book you illustrated is the one I used back in the early 1970's while still at school (in Ireland). The radio worked well and I entered it our annual school science exhibition which I was awarded 2nd prize. This started me on a road of electronic repairs and network installations which I still do for a living today (now 48). With the help of your article I will try and get my 10 year old interested in building this radio. I don't know where the original book ended up but your site has all the information I need. It brought back many memories.
Thanks, Philip Turner, Ireland.
[February 2010]

Hi Philip, There has been quite a substaintial amount of interest in this fascinating project - which is quite pleasing considering how old it is now. I think Rev. George Dobbs is quite pleased  - Good luck with the project!!!


  Greetings, Just a note to share with you how much I enjoy your web site. I'm retired and spend a lot of time on the web or with my radios due to my disability. I find your site to be a pure joy to visit. Now that I have found it I will visit from time to time. Well done!!

Best Regards,
Walter Dunbar Sr.

Hi Walter, Many thanks for your email and kind comments. We're really pleased that you enjoy the site. May we wish you happy listening and browsing.



  Hi Mike, I was reading your website and noticed the mention of Erskine T the dj who was on BRMB on Saturdays.I wondered if anybody would have any old recordings of the show as I used to listen and enjoyed the show. Erskine was given a Mobo award for his outstanding contribution to Black music in 1999.

Thanks, Carl Ingram
[November 2009]

Hi Carl,  Thank you for your email. Unfortunately we don't have a recording of Erskine T on BRMB, so maybe we can make an appeal to anyone stumbling across this page:

AN APPEAL - If you have any audio recordings of Erskine T on BRMB or, indeed, any audio recordings of BRMB from the 1970s and 1980's then we would be EXTREMELY grateful if you could send the to us here at MDS975.

Please use our contact page
HERE >

While we are about it we would really appreciate any audio recordings of MERCIA SOUND from the 1980's too.


THANK YOU FOR ANY AUDIO THAT YOU CAN OFFER FROM MERCIA SOUND and BRMB in the 1970's and 1980's


 
  Hi, I think I have found my nevada. Mike, I am currently looking for 3300 microfarads at more than 150 volts Radial, one end connections. I am G8BIH in Dorset, born 1936, the house is full of radio but at least the lounge is clear, thats full of Hi Fi.

I am quite amazed at your web site, it's quite an eye opener to what can be achived. Congratulations. Don't worry about the grammer etc, seems the Prime Minister is in trouble this way. Will try Birkett for the cap's. You would never credit it these cap's are fitted to a 100V rectifiered supply rail with 100V working cap's - they have all blown.

Hi John, Thank you so much for you email and for your kind comments - especially about the grammar etc. It's nice to meet another radio and hi-fi nut!! Good luck with the cap's. The originals were certainly NOT lucky!!  :-)  73, Mike.


I am located in the United States.  I enjoyed and learned from your site.

I hate to admit this, there seems to be more good (very good) electronic hobbyist web sites in the UK than in my country.  I don't understand why but I find an enormous amount of electronic info from sites like yours.

Thank you, Larry Gold
(November 2009)

Hi Larry, Thanks very much indeed for your email. It's always great to receive mail from the USA. Thank you for your kind comments about the site, they are greatly appreciated, although I am sure that you are being far too generous with your praise! We're really pleased that you found our pages interesting and helpful, however. Best wishes, Mike.




Hi Mike, Just a quickie to say how much I enjoy your website. It is a great source of inspiration to those of us studying amateur radio. Please keep up the good work. It is thanks to you and others that amateur radio keeps going.

I particularly like the cat section and yes our cat wakes us up the same way, ( I wondered why I had bruises every morning !!! ). I am studying for my intermediate now. I have come late in life to amateur radio, although I have always had a passing interest. I have to say that it is sites like yours and others that kindles interest in us non technical types, so as I say please keep up the excellent work and you should be justly proud of your work to further the hobby of amateur radio.

Thanks again.

Regards Richard. M3XIV
(October 2009)

Hi Richard, Thank you for your very kind email, we're glad that you like the site. The amateur radio section was written in the hope that it might be a source of inspiration for others, so I am glad that it seems to be working to good effect! Hopefully the links to other sites containing more detailed technical information are of help.

Good luck your further studies!  73 Mike



Hi Mike, Great site. I have enjoyed reading the history sections very much, and will be back!  I'm interested in finding out how the Regional [radio] Stations got given their call signs. I can find what the call signs were, Manchester 2ZY, Liverpool 6LV for example, but can't seem to find anywhere how these call signs were devised.  For fictional purposes I'm inventing a Station in Chester for wartime broadcasting (I know this probably breaks your factual heart, but just imagine that the BBC had not adopted the Home Service in 1939, what would a Station in Chester have been called?)

Thanks in advance for any light you can shed on this. Helen.
(October 2009)

Hi Helen, Thanks for your email and interesting question!  It's probably obvious how many of the call letters were derived: 2LO gained the letters LO from LOndon; 6LV gained the letters LV from LiVerpool; 5NG from NottinGham and 2EH from EdinburgH. 5IT in Biringham gained its letters from the area of Birmingham in which it was located - wITton.

The prefixes currently used for licensed radio stations in Britain are (I believe) 2, 5, G and M - this includes some allocations for amateur radio licences which will start with a
2, a G or an M, plus other private radio stations such as utility and marine etc.  I imagine 6 was (is?) used too, as in 6LV. I am not sure why London and Leeds were issued 2, while Birmingham was issued 5 and Liverpool 6. Someone else may shed some more light on this.

I you were trying to devise a fictional callsign for an imaginary radio station in Chester then it might end up being 2CT or 6CR perhaps!?

Best wishes, Mike.




  Hi,  My name is Michael, I am 15.  My grandfather was Peter Kingham, station manager at KLFM Radio in North Norfolk.  Sadly as you may know he passed away in early October last year. 

I'm just wondering if there are any recordings or photo's or anything I that could be sent to me and my family just as a reminder to him.  Being 15 I never heard any of his radio show's but I'd love to hear them sometime as I am a budding musician myself.  I know it would also mean a lot to my mum who is always telling me stories of him and the record shop and radio station.


I know this may not be being sent to the best person possible but if you know of anyone who may have some photo's or recording of him at the station could you forward on this message with my email address.  It is coming to a very difficult time in the year now for all of my family and I think it would be wonderful if I could make some kind of Video using any snippets of his radio shows and some images of him.

Cheers, Michael.
(September 27th 2009)

Thank you for your email Michael.  I am very sorry to read about your family's loss. I did not know that Peter had passed away. Please accept our condolences.

Although I only heard KLFM on the few occasions that I visited East Anglia from the Midlands together with a few DX opportunities, but I appreciate that Peter helped make KLFM into an excellent local radio station.  I am afraid that I don't have any recordings of KLFM programming, perhaps one or two jingles *maybe* but I appreciate that that is not really what you are looking for.

If anyone reading this can help with recordings and memorabilia of Peter Kingham on KLFM then please contact us at MDS975 and we will pass on the material to Michael.

Kind reply from Jim Warrack:

"I was very sad to read of Peter's death. I was heavily involved in the building and technical operation of KLFM. As you will recall KLFM was part of the Mid Anglia Radio Group which grew out of Hereward Radio. Next year sees the 30th anniversary of the launch of Hereward and we are in the process of organising a reunion next July. Please tell Michael I will ask our people if any one has any memorabilia of Peter.

Again my condolences to him and his family. Jim Warrack. www.paddockenterprises.co.uk " 9th October 2009.


Kind reply from Dave King:

"Hi Mike, I have just read your KLFM page with great affection.  I was so sad to hear about the death of Peter and read the note from his grand son. We are currently trying to put together a reunion of all presenters and staff from the old Hereward Radio days, of which of course Peter played a big part of. I would like if possible to get in touch with Peter's family and hopefully between all of us from Hereward and KLFM we can find some things, I know I have picture somewhere pre launch of KLFM.

Hope to hear from you soon. Kind regards, Dave King." 13th October 2009.

Thank you to Jim and Dave for their kind replies - it really is very much appreciated.



  Hi Mike & Jules,  Your site is excellent,  and I have spent many enjoyable hours looking through it.  The work you've put into it is amazing, and I always find something new to look at.  Your photos from Canada bring back such happy memories of when we were there in 1997 (That glass floor turned me to jelly!!,  and I've seen you've been to Washford also.

I do have my own little site, at http://dav-world.weebly.com  and I have gladly put two links to your site on it,  one on my Links Page, and one on my TV and Radio Page.

Do keep up the great work. Dave (David Ryder)
(September 2009)

Dear Dave, Thank you so much for your email, it is great to hear from you and it's nice to read that you enjoy the site! We have enjoyed two super trips to Canada and I did really enjoy visiting the CN tower and looking through the window. Washford was a good day out too. We have just returned from a few days in The Dordogne. We took a few photographs there too, of course, and we have put some on the website. We will put some links on the site for you too.

Great to hear from you, thanks again. Mike.



Hi Mike, I found your circuit diagram from the Ladybird Book handy. I think I looked at the book when it was new then made a radio based on that design. As I am looking for work just now, I have been putting together some tips on electronics and Electro-Magnetic Compatibility at:
http://myweb.tiscali.co.uk/andrew1lohmann/Electronics.html#TRF_Radio

I shall have another look at your website in due cause. Valves were lovely as they went like sparklers if you got it very wrong, but then worked again when you put it right if you were quick. Many modern FETs are as robust now, and they also have a triode region of operation if you wanted to get "valve sound".

Peacefully, Andrew H Lohmann
(September 2009)

Dear Andrew, Thanks very much for your email. It is very good to receive your interesting comments. The radio described in the Ladybird book provided me with hours of fun building it and listening to it. It seems may other people, including yourself, shared that fun. Thanks again and may we wish you the very best of luck with all your endeavours. Mike



I Googled for SL1200mkII and came upon your website and noticed that you are also actively involved in HAM Radio.  I am Abe Collins, KD0EIW in Colorado USA.  

I recently decided to try vinyl again and after some research on http://www.audioasylum.com/audio/vinyl/bbs.html, many "Asylum" members suggested the SL1200mkII as I didn't want to spend crazy amounts of money on a high-end setup.  I also enjoyed reading your detailed history on this series of Technics turntables.  Thank you.  My matte black SL1200mkII arrived just this week along with the AT120E cartridge and a phono preamp by Cambridge Audio (model 640P).

I haven't played my limited vinyl collection since the mid 1980's.  I'm loving it!

As for HAM Radio, I was originally licensed in California as a novice WN6UCS in 1971 then Advanced Class WA6UCS a year later.  I became inactive and let my license expire in the early 1990's but I passed my General test last summer and they gave me the KD0EIW call sign.  I am mostly on 2m FM these days as my community has antenna restrictions.

If you haven't visited Audio Asylum online, it's a great place where "audiophiles" from around the world meet.  I especially like the Digital PC Audio forum and more recently the Vinyl forum.  Please stop by and have a visit. Home page: http://audioasylum.com.  You'll see me there as AbeCollins

Hi, my name is Peter and I have the call 2E1MHA. My licence ran out some time back and I must renew it. Great website...I am most interested in the photo's and info about your Canadian grandfather. You see, I was born in montreal in 1960 and lived there until my mother, who was an English immigrant, brought me to the UK in 1968. I went back to Montreal for 2 weeks last summer for the first time in 40 years and I loved it. I wish to visit again..

All the best, Peter in Worcester, UK

Thank you once again for your advice Mike.

Very kind of you to take the trouble to assist. I purchased the Inverted L from
Spectrum Communications.....what a lovely company to deal with. Hmmm..going to have to make a few alterations to the support mast as you suggest. Hope you both had a pleasant holiday Mike; Thanks again for your time and expertise.

Very best wishes, Roy

Hi, Just a quick note to say I have really enjoyed your site and I do share the same beginnings of the (amateur radio) hobby as you did.  I took time and left c.b. radio [and] I am now doing my foundation exam on monday coming. So thanks for putting your page on the net. Amateur Radio page.

Thanks for your email Paul.  Best wishes and the very best of good luck with your endeavours. Mike.

Paul added:

Mike, Just too let you know i have passed my foundation exam .iam just waiting for my call sign now. I am starting my next stage of the ladder to become a full licence ham. I think your website is very good lots of good things to look at from the begginer to the full licence ham .

Hope to work you one day. 73 Take care from Paul, Marion and Georgia.

Well done Paul and thanks again.


  Hi Mike, Just happened to view your contact page and found a reply.... No  - a very comprehensive reply to my recent e-mail to you.......It seems I made a mistake in my [email] address !!!  But you were kind enough to post your reply on your contact page. I can`t thank you enough Mike for the trouble and care you have taken to advise me on my questions, and a whole lot more.... you are truly a credit to amateur radio........your advice more than made sense...in fact I was pondering purchasing over one or two of the verticals you don`t rate...so thank`s for that...also which TX to buy was giving me some trouble, but I`m going to take your advice on TX.  Re. antenna I will probably go with an `inverted L` that would suit my garden quite well. The `BRATS` on line training course is brilliant been using it for some time, thanks for the directive. Still waiting to sit the Foundation exam, so sitting in on intermediate lessons at my radio club to get some of that under my belt !! ...........

Thanks again Mike for all your time and care you have devoted to myself and I`m sure many others...God bless you and your
family.......Roy Anderson.

My pleasure Roy. Good luck with the exams!  Mike.


 Here's a message from my old school friend, Gary, who stumbled upon the Crystal Sets section of our website:

Mike, I do have to offer a belated thank you for introducing me to crystal radios.  Do you remember the electronic parts shop you used to get all the bits from down near the Robin Hood roundabout (I dragged my dad down there with the list of parts you recommended)?

I have since, built one with my oldest son, hoping that the magic of listening to crackly music hidden under the covers late at night will give him the same buzz that
it did for me (memories of listening to the eurovision results and John Peel!), a losing battle unfortunately compared to the hypnotic power of the playstation or Xbox.

All the Best, Gary

(April 2009)

There is certainly a real magic about the crystal set. It's a shame when others don't appear to appreciate it too. But as you say the Playstation anand XBox have hypnotic powers which I don't understand. Hey - at least you tried!

Good to hear from you, best wishes, Mike.


   It is refreshing to hear an honest perspective concerning vinyl playback. Most Rega and Pro-Ject turntables I have heard are completely unable to pass basic requirements for build quality and speed stability. They are afraid to post meaningful specifications concerning their performance.

The Technics SL-1200 is a music maker and makes me smile hearing it play my cherished vinyl. It sounds wonderful with all music. Nothing has as black of a background and is so devoid of rumble. If Rega built it, it would be sold for 80,000 GBP!

Thanks Kent - All so true!    The Technics SL-1200 Turntable


   Hi Mike, I found your web site very interesting and hope you don`t mind me contacting you. I'm about to take the [amateur radio] Foundation course after many years of shortwave listening. Please could you tell me how you found transmitting using only 10 watts on H.F. during your Foundation licence period? i.e. were you able to get out reasonably well?

I found your site while looking for equipment I may possibly buy once licenced. The Icom 706 mk11g, which I notice you use, is of interest. Antenna,...don`t know yet. I have a 47ft garden but thinking in terms of an HF vertical. Your comments would be appreciated Mike

Many thanks, Roy Anderson.

  Hi Mike,  Fox FM in Oxford is being re-branded as Heart on 23/03/09 as part of the very apdtly named Global Radio Group and will be no more. I worked for Elliott Bros Audio Systems in Oxford in the 80's and I built the 2 on-air studios. Clyde Electronics on-air desks and plenty of Sonifex carts machines i seem to remember. Thanks for the trip down memory lane on your Fox FM page.

As for me ? Just finish re-furbishing the BBC Radio Theatre at BBC Broadcasting House, how about a page or two on that.

 Hi Mike,  Thank you for your thorough and well written review of the SL-1200MK2. My experience is somewhat parallel to yours, in that I grew up with vinyl, hopped on the CD bandwagon, yet always knew there was something missing from CD playback (although the last 5-7 years major improvements have been made). Due in no small part to your excellent review, I have purchased a SL-1200MK2 at the low, low price of $395.00 delivered to my door. As a matter of fact, I got it yesterday and am still waiting for the cartridge to arrive, so I have not yet heard it.

For the past few years, always knowing that "someday" I would get back to my vinyl roots, I have dispatched a small army of vinyl finders scouring used book shops and estate sales for the best albums they could find. Armed with info on the best record labels, best vinyl condition and my preferences, they (and I) have amassed about ten lineal feet (about 9 meters) of some of the best wax we could find from the late '50's, the 1960's and early 1970's. My cartridge cannot arrive soon enough, as I am "chomping at the bit" to start spinning these albums. I tell you this simply to let you know that your review precipitated my SL-1200MK2 purchase and will soon open my ears up again to the vivid pleasures of vinyl playback. 


Thanks so much,  Rick Falgione

 Just to say thanks for your excellent website. Loads of interesting stuff. I especially like the historical info & pics. Found your site when searching for info on polyester capacitor voltage colour bands. Not into amateur radio myself (but my brother is - and vintage radio etc). My website: www.paformusic.info

Cheers, Mark (Coventry, UK)
(February 2009)


 Hello Mike,  While searching for a webpage on colour coding of resistors/capacitors, I came across your webpage and wow! I almost forgot what I was really searching for!  It was quite fascinating to go through your web pages on vinyls / crystal radios / ham radios etc. etc...

For quite sometime, I was transported back to the good old era of crystals, valves, turntables and had I been rich enough, I certainly would have ordered for a Technica Mk II turntable right away!  The sight of it almost made me drool !  I still have some old vinyls stashed away (Didnt feel like giving it away to the trash collectors here for whatever little amount they would offer - I'd rather keep them safe, whether I am able to use them or not!) and I do have a turntable too - what we used to call a record player here!  It still works, but the stylus is quite worn out and the speed too is not too steady.  Electronics was my first hobby (Spending more time with computers these days! ) and I did try my hand at crystal sets but the results were disappointing, mainly because I was not able to get sensitive earphones.  But my old valve radio (1969 I guess) still works, with its 6V lamps and all !

Amazing that we are able to share all the information through the web - Had you shouted from your rooftop even with a megaphone, I would not have had the pleasure of sharing your thoughts, so thanks to the web, I had a nostalgic experience in going through your website.
 
Great work!! Cheers to both of you :)

Hi Ajay,

Thanks for your email. It's great to hear from you and read about your experiences. If you are in range of a medium wave radio transmitter you should get some reasonable results from a crystal set, but as you point out you do need good (sensitive) headphones. In the absence of such headphones I have found that a crystal earphones can work very well, particularly those marked "Japan", as long as a parallel resistor and bypass capacitor are included in the circuit.

As for the vinyl record collection, I say to everybody - don't throw them out or give them away. Preserve your precious collection.Clean them up and start playing them and have hours of fun and entertainment!!


 Hi, I`m hoping you might be able to answer a query.  Would it have been possible to receive BBC radio broadcasts in the Hebrides (more particularly, the Isle of Skye) in 1938. I`m completely in the dark about this, yet I need to know.  If you can help me out I`d be very grateful. Best wishes,  Roger Hubank  (January 2009)

Hi Roger,

Thanks for your email.  I am fairly certain that the Isle Of Skye would have had no official medium wave coverage. The same situation exists today. There are no medium wave transmitters that provide daylight 'ground wave' coverage for Skye. Burghead and Westerglen, the nearest MF transmitter sites, do not provide a service area for Skye.

With a very good sensitive radio and / or a large aerial reception *may* be possible, but the signal strength would fall well below an acceptable minimum. The radios of the 1930's were almost certainly not as sensitive as some of the sets we have available today.

Here is a map, on MB21, from the 1960's. It happens to show the Burghead and Westerglen service areas:  BBC Home Service coverage in the 1960's

The situation was likely to be quite different at night, as the D layer dissipates and stops absorbing medium wave signals, these signals are then allowed t travel further up to the F Layer which will reflect them back down to earth. These 'sky wave' signals will be heard much further away from the transmitter than the daylight ground wave and would most likely allow reception of BBC radio on Skye during dusk to dawn. This is the reason why we can receive continental European radio stations at nigh very well all over the UK.

I hope that helps. Cheers, Mike.

Reply to Roy Anderson about Amateur Radio

Hi Roy,

Thanks for your email and good luck with your exams.

There are many enthusiast "QRP" operators who get around the world with less than 5 watts, so don't be  too worried about "only" having 10 watts. Having said that low power operators will often use the most efficient modes of transmission - this is why Morse Code is so popular with QRP operators. It's far more efficient than voice modes.

Having said that, SSB is far more efficient than AM or FM since, as you will learn, if you haven't already, SSB concentrates all your available transmitter power into one sideband, rather than wasting what power you have over two sidebands and a very wasteful and unnecessary 'carrier'.

Given favourable conditions you should be able talk all over Europe.

The bad news is that, as you may know being an SWL, the sunspot number is currently at absolute minimum. This means that propagation on the higher short wave bands - which make for superb long distance low power operation - is almost non existent at the moment. This forces operators down onto the lower bands which can then become rather congested.

However you may benefit from from 'Sporadic E' on the high HF bands such as 28MHz in the late spring / summer months which can be very exciting since QRP signals often come in like locals.

As for your transceiver then, unless you want to spend thousands of pounds, the Icom IC 706MK2G and the Yaesu FT857D are obvious choices since they cover all the popular and well used bands of interest and have many facilities that would have been completely unheard just a couple of decades ago - and certainly nowhere near the reasonable price that these sets sell for today.

Each radio has pluses and minuses - e.g. the 857 has some very nice and useful audio tailoring facilities that the 706 lacks and, I'd say, the DSP on the 857 is more pleasant on the ear than the 706. However FM audio quality is, to my ear, more pleasant on the 706 and I also find the ergonomics on the 706 slightly more appealing.  If I had just one I'd be quite happy with either model, they are both absolutely amazing really, but on balance I prefer operating the 706. In the end it's really down to personal choice which one you choose - you really would be happy and flabbergasted by the abilities of either transceiver.

Successful operation is not really about how big your radio is or its brand or model number.  There's a lot of hype over equipment that tries to persuade you that so-and-so £3000 radio will "get you out" much better than some other radio - but as far as the transmitter goes, if both radios are 100 watts then one is not going to give a bigger signal compared to the other - a 100 watt radio is a 100 watt radio (Just as 10 watts is 10 watts; 50 watts is 50 watts) no matter what particular radio you have; It's what you do with your 10 watts or 50 watts that counts....

1/ Microphone and Audio Processing is important - but there's another area that you'll be persuaded to spend a fortune on. You do need some processing - "audio compression" - to make the most efficient use of your SSB signal, but radios such as the 857 and 706 have compression built in and that's really all you need as a general operator. You can use better, narrower filters, and even experiment with some external home-brew (D.I.Y.) audio filters and processing. If you get into exotic and extreme DX and you are operating the radio for many hours every day, then maybe spending £thousands might become worthwhile.

2/ The most important area to devote you attention, time, study and money to is your antenna and earth system. Improvements you your antenna will be far more rewarding than constantly changing radios - as, arguably, too many operators seem to do!! (But it is fun - albeit expensive).

The key to putting out a good signal - especially if you are using QRP or Foundation power levels - is to use the most efficient antenna possible. This usually means using a "resonant" antenna, i.e. one that is tuned for the particular band of interest. As high as possible helps greatly too. This will ensure that your transmitter power is used as efficiently as possible.

Your antenna really is the area where you should concentrate your efforts - no matter what power you are using. Just a seemingly small 3dB loss of antenna efficiency is like reducing your transmitter power from 10 watts to 5 watts!

Think tuned Dipole, Inverted V, or Inverted L or something like that.

You will see all sorts of rubbish advertised in the press and on the internet  that claim all-band coverage. e.g. the Q-Tek Penetrator and similar physically short, wide band antennas promise all band miracles.  The 'miracles' are impossible! These compromised antennas may seem attractive since they claim to offer you all of the HF band in an aerial that's only a few meters long. Trouble is they are far too short - relative to the wavelengths that you're interested in - to be usefully efficient. Maybe as much as 90 percent of your 10 watts will be wasted  as heat generated in the loading coils of such antennas. Do you fancy working with 1 Watt??

With low power - or any power really - the key is to use an antenna that is resonant on the band that you are using. This will ensure that as much of your very valuable and limited transmitter is transferred to the ionosphere and not wasted by converting it to heat inside the expensive but often useless branded antenna.

Ignore anyone who tries to tell you that a Q-Tek or especially an "Antron 99" make good amateur radio antennas. Unfortunately they do not. They will radiate, and they may very well make contacts far and wide - but efficient they are not. You could make several very much more efficient tuned antennas that will work much better for the price that these and similar antennas will cost.

Buying a superb radio like an IC706 and using a poor aerial is like buying a 50 inch plasma TV and feeding it with a set-top television aerial!

You will learn a lot about radio, propagation and antenna design by making you own aerials. You'll also save a LOT of money too!

Do bear in mind a couple of simple truths:

You could build the most efficient antenna in the world, but if the sunspot numbers are low and propagation is poor it will *seem* like the worst antenna in the world when you don't hear anything on it!! (- So wait for conditions to improve.)

Alternatively you could use an incredibly inefficient antenna - an Antron 99 etc etc etc - and make some worldwide contacts - simply because sunspot numbers and the propagation might be at their peak and be offering exceptional propagation conditions on a particular band. - Sometimes when propagation is excellent you can hear multitudes of stations on a 'piece of wet string'. It doesn't make wet string a good antenna of course!!!!!

It's for these reasons that it is absolutely and entirely impossible to make any useful comparison between one person's anecdote about their antenna with someone else's anecdotal story about their particular aerial.

Good luck with your exams. Following the study courses you'll easily pass the Foundation and the Intermediate. With a little more application you could attain the Full Licence in a year or so.

Whatever radio you get, an 857 or a 706, you'll love it, but don't forget your resonant and efficient aerial!!
