Long term store and forward? Have it log APRS formatted messages sent to
a specific user (SPACEACE). When the unit is recovered, post the results
to a website. 

Could you tell the good guys from the bad by having the good guys use a
PL tone and subtract that data from the whole leaving (mostly) bad guys?

What sort of orbit is this likely to be in? Which frequencies would you

Subject: [amsat-bb] RX only satellite?

There may be a Satellite opportunity for a ham radio RX only payload.
No TX allowed.

Any ideas?  It will be recoverd one year later.

All I can come up with is a satellite band moniitor that scans the
satellte bands and makes a one year survey of QRM and stores it in
flash.  That is, recording frequency and signal strength and position
for a year.

Problem is, I cannot figure out how we could use the data to tell the
good guys from the bad guys so it wouldn't tell us much I don't think?  

Any other ideas for a RX only space application?  Of educational
interest?  Anyone interesetd in developing the band monitor payload?
