I first became interested in DXing in the early sixties at the age of 14 when I was given an old broadcast receiver with bandspread and became fascinated with the number and variety of shortwave propaganda stations that I could pick up with a wire antenna. A little later I discovered that by fiddling with coils in the receiver I could hear many local radio amateurs on 160 meters who were at the time mainly using AM, SSB being newfangled then. One night at about 2am however I was excited to hear an American medium wave station and this spurred me on to build a large loop antenna which enabled me to hear medium wave stations from all over the USA and elsewhere and build up a collection of QSL cards and spurred my interest in radio propagation.

I passed the three hour written UK Radio Amateurs' Examination in 1969 but waited until I had finished my degree studies before obtaining my Class B licence G8LDR in 1976; and then the Class A G4SWY after passing the Morse test in 1983. I was then very active on 2 metres SSB and RTTY and was an early adopter of 6 Meters when that nand becae available in the UK. I also ran a popular packet mailbox for a couple of years.

I am currently working 6 Meters with a homebrew Moxon antenna and 10 Meters with a dipole. I enjoy contesting on six and also chatting on my local GB3HR 70 cms repeater. If you hear me on an HF band then I will call myself DEL instead of Derek as that is easier and is what my family calls me.

I am now enjoying my retirement from IBM where I was a software developer but am still writing software for Windows PCs and Android devices. My other interest is birdwatching, (see photo)

An ongoing amateur radio software project is to map WSPR spots on Android devices in order to view propagation conditions. See https://play.google.com/store/apps/details?id=xxx.wspr.g4swy and my blog at http://wsprnet.org/drupal/blog/58732

Another published Android project is 'Pocket Prefix' which easily and rapidly looks up detailed information about Amateur Radio callsign prefixes. See https://play.google.com/store/apps/details?id=g4swy.prefixdecoder.lite
