RX only satellite?




It would be interesting to look at the NCDXCC HF beacons from space to 
get an idea of ionospheric absorption.  These have predictable times 
and variable predictable power levels, so path losses can be easily 
calculated.

Monitoring the 10M frequency at 28.200 might provide useful information 
for future Mode A applications. With beacons all around the world, 
broadcasting every 3 minutes at known power levels, a 28.2 MHz receiver 
could provide a wealth of information. The beacons ID themselves, so 
data analysis should be easy; all that would be required is some sort 
of time tagging. I suspect that the satellite would never be out of 
range of a beacon.

How much data storage is available?  I need to calculate how much data 
you would need to  obtain.

It would be interesting to launch these satellites at various points in 
the solar cycle. - Duffey KK6MC/5
