I wasn't aware of Jim's BPSK tests on saturday, but as I heard a
'suspicious signal' in the digtal mode segment I decided to record a 1
minute WAV file and let WOLF have a try on it.
Result : a 100% copy at the firsqt attempt. But Jim's signal is about 25dB
over noise here, so it wasn't a real challenge.
Using DL4YHF's software as spectrum analyzer I noticed that the bandwidth
was about 20Hz, so one should stay out of the QRSS segment (above 137600)
with BPSK.
I would like to do some more tests with weaker signals, if WOLF  is as good
as told (100% copy at -40dB SNR) than Jim could reduce his power by about
65dB.
Jim, is it possible for you to reduce power in steps, let's say -6dB every
10 minutes. I believe you could start at a level that is 20dB down on the
power you were running on saturday (at least for me).
