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.
