I wonder if anyone has consdered RF modules for a satellite.
I have been playing with a module called "Easy Radio"
It takes care of the pre-amble, bit flipping and CRC. Freq = 433.900 MHz
They put out in the order of mW, but I put a 30 watt amp on the end and wow !
The data burst is 180 characters max, and it takes around 25ms to send.
These are cheap, they cost around $80 for a full data transciever.
It would eliminate a whole lot of stuff on a board.
I used them for a glider tracker.
Anyway here are some photos of what I am talking about.

Is the difficulty in building the satellite, or getting it up into space?
