[amsat-bb] Secondary mission ideas

[Ev Tupis]

 How interesting!
In very general terms: QSO Robot
Ground stations TX to the satellite using CW or PSK31 (so multiple uplink signals can spread out through a 3 kHz uplink passband.
The satellite responds back on a single frequency.
This happens all the time on HF where DX stations listen from 14.300 to 14.310 while responding on a single frequency like 14.290.
Concept presented. Details can be worked out later.
By the way...the now concluded PropNET Project used this concept for a decade...quite successfully.

Cheers,Ev, W2EV

 I just had a super call with a university program flying a mission using
SDRs. We talked about licensing and coordination issues, and discussed ideas
for a secondary two-way mission that they want to do. 

 

What would you like to see, repeater, transponder, BBS, digital voice,
digipeater? Downlink would be on 2m, and would probably be limited to
20-25khz wide. Other ideas? Something new and different? Let's have a
civilized discussion about what they could try, as they seem to be an eager
and capable bunch.
