... I noticed another weak signal had been
recorded at around 137.740kHz.
It turned out to be sending the same data as GM3YXM/P but with a
mystery delay timing difference of around three seconds.
None of the signals was strong enough to cause non-linearity and
there was no evidence of soundcard 'AGC' action that you sometimes see.
So is it some sort of strange propagation effect? Most likely some
image effect of the SW or soundcard- but why the time difference?
