OK, I've just seen it happen!Believe it or not, I've been watching FLDigi for an hour now, and I just saw RxID turn off. The message in FLDigi was "Before RSID: <<2010-01-31T09:06Z BPSK-250 @ 3580000+1000>>" There was no received signal. FLdigi did not transmit anything (the radio was not keyed).
Do I have something miss-configured? I think this is it! Steve.
