Hi Jean Pierre,
the overlap is due to the length of the FFT, which
spreads the signal in time to the inverse of resolution bandwidth. If I
recall right you are using 11 mHz bins, ie. about 90 s integration time.

Hi Markus ,
Thank you for this attempt of explanation . I think that
it is about another station . Because Joe (NA)cannot be on two frequencies
to the same moment
(to see capture)

Jean Pierre,
the 137776.4 Hz signal should be the dot frequency of
VO1NA's ultrawideband DFCW ;-) At the top, there could possibly be a
trace from XNS on 137781.
Best 73,
MArkus
