[amsat-bb] request detailed system diagram for remoting a satellite station

[Peter Goodhall (2M0SQL)]

Sadly Satnogs isn't suitable for the job being it's for telemetry only,
also I don't believe it forwards telemetry to AMSAT-NA or AMSAT-UK so radio
amateurs would be better off with a different solution.

Sadly ICOMs remote software isn't that great for satellite work, I'd also
love to see a better remote solution even if it's just for working passes
in a different room in the house.
