Born in England June 1943, Age 73 Graduated,London Univ.1971, First licensed in 1974 as G8HTY - Passed CW in 1982 and issued with G4MKI - Holder of Notice of Variation (NOV) for APRS Internet Gateway as MB7UEK issued 04/02/01 in the first batch of 16 new licences issued by Ofcom. RSGB Member
Main interest is in PSK on the HF bands (EPC Member #3247) and AX25/APRS packet on 2 meters. Beta testing G8BPQ 32 software for Windows (BBS, Node (with worldwide udp internet linking)and BPQAPRS Internet Gateway,also G8BPQ's Linux piLinbpq for the Raspberry Pi and associated piTNC's ( a 2 TNC stack in I2C mode).
BPQ software is running my station very reliably 24/7.
Details of all G8BPQ development I have supported are documented on my website.
My worked DXCC's are primarily for data mode contacts only (since 2006),using 30W into a 20m dipole or G5RV. Electronic confirmations are via eQSL and LoTW. I do not normally send paper QSL cards or claim awards using them. Reason: According to LoTW, I have 2808 QSO's on record of which 766 have been confirmed by QSL. The ratio is slightly better for eQSL.
