Greetings all,
Do we have a relatively stable, but not too strong 'carrier like'
signal in the vincinity of 137 kHz,
to get a rough estimate of the local QRM level (by comparing that
signal's SNR with the same receiver bandwidth, say 1 Hz) ?
I get the impression that mine, with a loop antenna (low-impedance,
broadband) dangling under the roof, is far too high.
I didn't manage a single decode yet, which I first blamed on a bug
in SL's timestamps (written into the decimated wave file), but since
there was also not a trace of Joe's signal in a high-res
spectrogram, I have my doubts..
73,
