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.
I response to our correspondence regarding his Rega Planar 2 turntable and replacement phono cartridge for playing a collection of vinyl records Eric writes:
Hi again. A comprehensive and generously helpful response.
Very many thanks once again for all your help and advice....more than enough to restore anyone's faith in the internet.

[January 2012]
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.
 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.

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

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

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

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

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,

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

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

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!

Dear Ivan, Thank YOU very much for your email and thanks. Thank you you
also for your excellent service, that I mentioned on the web page.
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.

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.

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.

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.

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

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

[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.

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)
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, 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!

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

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

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 - 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

nights a week!
Cheers, Norman.

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.

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!!

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!

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.

[July 2010]
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.

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

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

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

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

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.

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

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.

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!

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

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

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.

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!!
73 Mike
