I measured the frequency difference as 1.75Hz at 20.30UT (using
Spectogram). I can not measure absolute strengths but the higher frequency
was 2dB stronger here.
Both signals were well above noise, when they were transmitting at the same
time the 'zero beat' was clearly audible (sounded as a signal with fast QSB).
I recorded it as a wav file and and determined the frequency difference by
measuring the 'zero beat frequency' (time between 2 minima or maxima),
result was 1.73Hz
