This is a silly idea, but what's the math as far as an AM transponder?
AM would have less of the capture effect -- maybe weak signals might
be audible, though maybe not intelligible. Could possibly result in
simpler, no-doppler ground stations. Don't some of the HT's support
AM these days?
Another idea I had, four FM receivers, one transmitters. The inputs just
mix together on the satellite. The power all goes into the
one transmitter, and gives more chance for multiple people to exchange
calls. The big guns can have their long chat, and then the other callsigns
that people are exchanging would just be heard on top of the
conversation when they send to the other receivers. I've heard
this kind of thing on ssb.
