[amsat-bb] HF Satellite Transponder

I may have a launch opportunity for an HF=HF transponder for a possible
cubesat idea.  Probably something like 12m up and 10m down?

Is this worth doing (re-doing) at this point of technology?  Enough
bandwidth to support a few voice channels?

Any volunteers to build the translator board?

How is 24 MHz band used?  The entire SSB portion of the band is only 60
kHz, so using say 15 kHz for a linear translator to 10m would be quite a
slice.  But then the downlink at 10m would be OK since it does have an
exclusive satellite band and so any inadvertent QSO's would be coming down
in a non-competing downlink

Just some open ended thinking after Dayton.
