I'll agree with that one also, a whole bird with one "Channel" seems like a HUGE waste. Cool? Yeah,, but single user uh,, nah.
I'm old skool oscar 6 & 7 and the old russian birds, FUN!
In preperation to a long distance balloon flight coming from Arizona soon, I experienced PSK31 for the first time the other day, and what a cool mode!
Just now I was listening for the test beacon for the balloon, with a "Online" reciever, not even my own, that has a generaic all band antenna so it can listen from 500Khz to 50 Mhz, imaging the efficiency of that antenna!? Anyway with this rig tuened to the beacons freq of 14070.45KHz it's amazing, using Digipan as the software, i was watching and reading 16 QSO's happening all at the same time on the one audio passband! People can be like 50 cycles away and have perfect QSO's,
is this mode used on the birds much? what a bandwidth saver.
