Please may we have a new mode in the database namely ATV?
Homebrew ATV equipment and batteries are miniturising and becoming more innovative that British Amateur Television Club members are starting to operate from hilltops and high places seperated from their cars. G0HIK and friends have already had S2S contacts on 6cm FM ATV in Lakeland.
Since getting my MG status in October 2016, I shifted to a new challenge of building a digital ATV station. I joined the BATC just in time for the Portsdown DATV transmitter project kick-off. With lots of help from chairman Dave G8GKQ and a devotion to reading the instructions on the Wiki, I’ve built a 4-band DATV station in a wooden rack that sits in the boot of my estate car with 2 104Ah standby / cyclic VRLA batteries. It’s massive. From a good site I can Tx and Rx video over a 100 mile path on DVB-S2 putting c. 10W into the beam.
Where the technology is going now is that a Raspberry Pi4, 7" touch screen, USB sound dongle with mic and pi camera will operate a Lime Mini SDR and a Minitiouner receiver. Adding a 70cm or 23cm amp and antenna with some class of Lithium batteries means a single band DATV station would have pack weight around FT-857D transceiver /P station levels. I also a have 6cm FM ATV station built from drone first person video units, a decent uwave coaxial transfer relay and a Gibeon patch antenna.
So ATV mode in SOTA is ripe for encouragment please.
