Hi Patrick,

Here is the feedback from Alan:

Each byte is the high bit first, and the telemetry channel information is sent in the order of the sequence number and the low sequence number is sent first.

Thank you, Peter!

I sorted those errors out, but we still get those undocumented frames.
Did he tell something about that?

I asked for it and let you know if I get additional information… 73s

interestingly, the manual is also mentioning an X-Band transceiver payload.
I’ve asked Alan for information and will post details when available.
