Markus, Joe & JT9 entusiasts
Finally got my first "15P6715P67WCV" decode
last night after quite a few hours of JT9 operation over the past week. It
appeared while running tests with WSPR and JT9 operating simultaneously.
Because of the disparity between input signal levels between WSPR and JT9
the signal strength in JT9 was about 55 on the green scale. There was also
a - 25dB WSPR signal in the passband at the time but I don't believe that was a
factor. Backing down the audio input to the JT9 decoder eliminated the
false decode. It would appear that "15P6715P67WCV" is related to
strong signal input to the detector - either background noise/static or actual
signals.

Subject: LF: JT9 yesterday evening
Three times "DK7FC JN49QRP" decoded in JT9-2, and
a couple of "DK7FC JN49IK" in five minute mode with +9 dB
SNR. But our well known friend "15P6715P67WCV" appeared many times
throughout the night...
Best 73,
