    SEA inbound rate limiting.

    You can see other planes being delayed at the same time.

    Even for port 10001 SBS has different output formats for different firmwares or versions of the device i believe.
    It may just be that MSM2 doesn't support all of them.

    you excluded the most relevant graph: the first one, message rate.

    Both settings are probably fine.

    That's with the blue Flightaware stick and the 50$ AirNav antenna in a window?

    With a gain of 49.6?
    That's actually a little surprising.

    Does the command

    There should be a percentage of messages >-3dB displayed. (first graph)

    You don't want more than 5% of them, as a guideline.
    But you don't want to turn down the gain too much either.
