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

    eggbeater antenna -> LNA -> LMR 220 -> RTL-SDR -> FreeBSD

    What's your favorite eggbeater and why?

    What's your favorite LNA and why?

    Thank you in advance.

    Danke,

    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?
