Fancy going portable to escape the man made electrical QRM and the ever encroaching blight on the radio spectrum by BT Vision and You View TV by Broadband Power Line Adapters - (PLT), HomePlug, and other disastrous PLT / PLA / BPL devices?

Well, after viewing Diana Eng's inspiring video ( page 1) I was prompted to look into what's required and so I started compiling a list of ideas which I noted down and have now presented on this page in case it may help others.

Portable operations could be a few hours on any hill with lightweight and minimalist equipment such as a hand held with a separate lightweight antenna, or 'activating' a qualifying summit for an award scheme such as SOTA or HuMPs or a weekend away camping in a bivouac or tent with a more comprehensive set of equipment.

The Wrekin, Shropshire - SOTA Summit G/WB010 
Grid Reference: SJ 628080  |  QTH Locator: IO82RQ  |  407 metres a.s.l.


On the afternoon of the 27th August 2013 I decided to attempt the ascent of The Wrekin, near the town of Telford in Shropshire.

I had not walked up The Wrekin previously so I wasn't quite sure what to expect.

For me The Wrekin is well known for being the site of an important medium power television transmitting station that provides the terrestrial multi-channel digital television service (BBC, ITV, Channel Four, Channel Five and other commercial television channels) to Shrewsbury, Telford, much of Shropshire and parts of the western West Midlands, Staffordshire and the Wesh Borders.

The tower, which can be seen in the background of two of the photographs below, was built in the 1970's and also supports the transmitting antennas for various other radio services including DAB digital radio multiplexes 12B (BBC), 11D (D1) and 11B (local), the 2.7 kilowatt (e.r.p.) VHF/FM transmissions of Free Radio 103.1 MHz and the 5.0 kilowatt (e.r.p.) VHF/FM service of BBC Radio Shropshire on 96.0 MHz FM stereo. [ More about The Wrekin on MB21 here]

The walk to the summit is quite steep in places and about 2km in length. I had a large ruck sack on my back which was surprisingly heavy and slowed me down. I had allowed myself an hour to walk up from the car park to the top, but in the event it took me about an hour and 20 minutes with four stops along the way. I was certainly relieved to unload and sit down once I had reached the summit! The back pack contained two hand held dual band transceivers (Yaesu FT-60 2m / 70cm and a Wouxun KG-UV6DL 2m / 4m); a 10 Ah sealed lead acid battery; a fibreglass telescopic pole; guying kit; dual band SOTA beam; coax cable and patch leads; a box of connecting cables and battery eliminator accessories; log book & band plans; foam seat pad; water bottle and lunch (!) and some alternative warm clothing.

I set up station not far from the trig point. The Wrekin affords spectacular views across Shropshire and adjacent counties, however visibility was somewhat impaired for my visit, with a persistent light mist.

I had intended to use my Yaesu FT-60 with the 3 element 2 metre SOTAbeam for the activation, but unfortunately I found that the poor little Yaesu's front end was completely overloaded by the nearby strong transmissions and I could not receive any other stations at all.

I was about to 'up sticks' and move a little further away from the transmission site, but then I thought that I'd try the Wouxun KG-UV6DL handheld before moving.

I was very pleasantly surprised to find that the Wouxun KG-UV6DL coped much better with the strong signal conditions and intermodulation problems and RX was greatly improved with a surprising contact with Paul M6BLU on his handheld from the beer garden of a pub in Aldridge. Very nice, thank you Paul!

On the walk back down the hill when I was further away from the transmission tower, I tried the FT-60 again, this time with the 'rubber duck' antenna. The RX was much better and I made contact with M6STD mobile near Shifnal, Nick M3SLQ in Cannock with very good signals and also Bob M1CYI in Walsall.

All in all I had an extremely enjoyable afternoon an spoke to lots of interesting stations. Great fun!

Thank you to everyone who contacted me. Please see the log, below, for more details.

SOTA - Summits On The Air. Qualifying SOTA Summits are 'Marilyns' i.e. hills / summits with at least 150 metres prominence: http://www.sota.org.uk/
