At first I was going to say "perhaps K9SA has PASSALL enabled and is corrupting
packets" but that wouldn't explain the "QIDE2-1" or the "WIHE2-1" so that points the
finger at N9MXT-10, but then a different iGate AB9FX-1 was involved inn the 3rd
example. I don't know the signifance of the "<0xf0>" and "<0x01>".

Different digi. Different iGate.

There's K9SA again, and  different digi. Is there a problem with it? Perhaps
it isn't PASSALL and RF is getting into the TNC there and messing things up.
