QSL policy, from November 2017 ; I am very sorry, but after a lifetime of radio operating I can no longer send paper QSL cards either direct or via the bureau, nor do I wish to receive any paper QSL cards, please don't waste postage sending QSL cards to me.

I do however upload to the ARRL Logbook of the World  -  LOTW - regularly from my logbook, as well as to eQSL to those that use that service.

I don't apply for awards myself, but do try to keep accurate records of my QSOs for my own studies, using VQLOG.

2017: I am now using an IC-7600 for 144 MHz with a G4DDK Anglian 2 transverter module transplanted into an ME2T transverter box with a 28 MHz I.F. this drives the legal limit Gemini 2 LDMOS PA and 1kW for EME (Special Research Permit for QRO). The 116 MHz Local Oscillator of the transverter is frequency locked to GPS using a Leo Bodnar PLL.

October 2016: Increased power available on 70 MHz to 160W at the antenna, and 50 MHz now 200W when needed courtesy of a Gemini 4 LDMOS amplifier. 

August 2016: 50/70 MHz dual band yagi 4/5 elements on 3.5m boom constructed. IC-7300 barefoot on those bands.

April 2016: Now some 432 MHz gear, 18 element yagi by G6HKS at PowAbeam WS718562  and Italab LDMOS SSPA (thanks Nico) running 400 watts at the antenna. Masthead preamp soon. FT-736R currently, but will build transverter so that I can use a more modern HF transceiver.

May 2015: You may have seen my WSPR QRPp beacon on the HF bands. It ran 250mW from a Hans Summers U3S kit I made. (QRP Labs). Frequency and time was GPS conditioned. I no longer have the U3S, as it is with a new owner.

June 2015: Now back on 144 MHz with a WAXX10S yagi (10 elements horizontal on a 5m boom) G4CQM design with coaxial dipole feed with boom material and clamps supplied by G6HKS. Rotator is a SPID RAK (thanks Jacek) fitted on a 2 section Versatower. Feed line is 20m of 7/8" Heliax plus a length of Westflex 103 around the rotator. No elevation, or masthead preamp.

A Strong Visual Aurora at my location in Scotland - The antennas are illuminated by nearby sodium street lighting.
Photographed on 24th March 1991 at approx 23:30 UTC using 200 ASA film, 50mm lens, f1.8 with a 10 seconds time exposure with a Canon FTbn SLR. The photograph has appeared in a few RSGB publications, but not however in colour and actually looks as if it was taken in daylight in some publications!
