RSGB 2022 Convention - Digital ATV - Opening New Horizons

Dave Crump, G8GKQ
Dave describes how easy it is for the home constructor to transmit and receive digital ATV without the need for the specialist camera or receiving equipment that used to be required. After discussing the flexibility that Digital ATV offers for trade-off between DX and picture quality, he talks about the opportunities that there are for ATV contacts and experimentation by normal propagation, sporadic-E and through QO-100. Discussion includes all bands from 28 MHz to 122 GHz.
Dave, G8GKQ gained his licence at the age of 14. Within a year he was active on ATV on 70cms, starting with 405 line black and white but graduating to 625 line colour as soon as homebrew designs became available. After university, Dave joined the Royal Air Force as a pilot and continued to construct and operate ATV equipment from all corners of the UK and in Germany. During more recent overseas postings to the USA and United Arab Emirates he had less time for radio but has made up for it since retiring. He has been on the BATC Committee for over 15 years and now leads the design team for the BATC’s Portsdown Digital Amateur TV Transceiver project.
