The information on this page is mostly now obsolete. I leave it here for historical reasons! G4HLX and F5VLD have been off-air for some years now.

If you're looking for my popular National Grid Ref to IARU Locator convertor, you'll still find it here.

History and interests

First licensed in 1971 as G8EQX (callsign now held by my son, Ben) and then as G4HLX in 1978. Have been active on all 13 bands 1.8 MHz - 432 MHz, but my main interest is VHF/UHF, particularly DX and contesting.

Since 2006 have been working in Provence, France, and active on some HF bands as F5VLD, in Aix en Provence. Also sometimes active on D-Star, as G4HLX during visits to the UK, or as F5VLD by DV-Dongle.

Activities have included amateur satellite operation, using various satellites from OSCAR-6 through OSCAR-23 and AO-40. In 1980's wrote software for ZX Spectrum computers for receiving text bulletins, telemetry and images from UoSAT/OSCAR-9 and 11 with no hardware decoder. Over 600 copies of this software sold.

User of packet radio on 144 MHz since 1984, and for some years ran the Oxfordshire hub station for TCP/IP packet users on 144/432 MHz. Pacsat operation including 9K6 through UO-22.

In 1982 conceived the idea of the Practical Wireless 144 MHz QRP Contest, which in 1984 became the best-supported VHF contest in the UK of all time. Ran and adjudicated this contest for Practical Wireless magazine annually 1982-2007.
