All about Phil Cooper GU0SUP
As you will have seen, my name is Phil Cooper, and my callsign is GU0SUP.

I now retired, but used to work in a small electronics factory where we build circuit boards for many companies.
Check out for more info.

My job was checking boards after they have been through the surface-mount process, and repairing any defects found. It was more of a hobby than job…

My Home
Below you can see where I live together with my XYL Penny.

XYL Penny





Penny and I were married on 8 September 2000, at St James concert hall in Guernsey. It was the second time round for both of us!

The picture shows Penny and I inside the hall.


My background, and amateur radio
I was born in 1953, in London, but grew up in the forest around High Beach, near Epping, Essex. Itchy feet took me to Guernsey in 1974, where I seemed to have taken root! I was first licensed as GU7LSX on 10 February 1992, and then got my full license on 20 December 1992. However, my first HF contacts didn’t start until January 1993. It took me 5 months to start using CW on HF, and then, in 1994, I discovered the joys of RTTY. Since then, I haven’t done any SSB, and my main interest lies in the digital modes, although I still use CW occasionally.

Despite forays into PSK, Throb, MT63, my preferred mode is still RTTY. Originally, PSK was great, as everyone was checking each others signal levels, and help was abounding, but now, it would appear too many people “plug & play” and just go, with little or no consideration given to ALC levels, etc etc. In the early days of PSK, most people were happy using 5 watts or so, and this was great, Nowadays, it is not uncommon to hear folk boasting of using hundreds of watts.

You will find me in most RTTY contests, and often on the WARC bands with RTTY outside the contests.

I now have DXCC on all bands 80m through 10m.

I am the RSGB QSL sub-manager for the GU and MU series calls, and an RSGB GB2RS Newsreader for Guernsey.

I am a member of the Chiltern DX Club.
Besides amateur radio, I enjoy sea-fishing and stamp collecting. I also keep tropical fish, and have a pond in which I keep Shubunkins and a few Koi.
