Hi Bob,

That would probably be hard. Most likely the 5GHz OFDM downlink only
works by request of the groundstation. Also, a OFDM is rather complex to
reverse engineer and such.

Let us first try to get some information from the team regarding the
70cm telemetry, since this transmits continuously and uses a much
simpler protocol (but we're still unable to do much).

In any case, anyone with the appropriate receiver can give it a go and
try to record the 5GHz downlink during a pass. If something shows up in
the recording, it would be interesting and I would surely give it a good
