It seems best to start with the receiver. Here's one simple receiver

eggbeater antenna -> LNA -> LMR 200 -> RTL-SDR -> FreeBSD
What's your favorite eggbeater and why?
What's your favorite LNA and why?
Thank you in advance.
Maybe ask persons who use AmSat (an amateur-satellite initiative).

Joseph A. DiVerdi [1] hosted a last minute, surprise forum at our
Division's Ham Convention [2] last August. He brought along a 3U
satellite to show off at his vendor's table.
Instead of thrusters, it spins a miniature momentum wheel. A de
rigueur RTL-SDR and Raspberry Pi sat next to the satellite on his table.
Long story short, an EB144RK2M eggbeater will be used, along with a
cheap LNA module from ebay [3]. It ought to be easy enough to replace
the original LNA chip, if anyone knows of a superior LNA chip.
Note.

Nice board, did you test it?
