FM-up and FM-down.
One transmitter on 432.
Multiple receivers on 2M -- maybe 8 would be cool each set to
a different frequency, each with a distinct PL tone for access.
On the satellite each of the receiver ports is mixed together at audio
frequencies and output
on the downlink. The volume of the mix is determined by S-meters and
signals on the uplink are mixed in at lower volume.. The more power you
use, the quieter you sound. This is so while the big guns are
at very quiet, low audio, the guy with the HT has a chance to break in
The idea here is to make a satellite where the HT's have a chance.
receivers make the system usable over areas where pirates are
the uplink channel. (Provided pirates aren't on ALL the uplink channels.)
