Using the pass from 09:45 UTC this morning, I recorded some CW from the beacon which peaked around 35-40dB over the noise. If I decode it in dl-fldigi (via an 8kHz, 8 bit WAV file) I get this output (for reference it should look like this):

If I use the new version of MulitmonNG I get this (using the standard default arguments - i.e. not changing -g or -d):

So multimon certainly doesn't do a bad job, but it has some room for improvement. I'll try tweaking the values of -g, -d, etc and see how that changes things.
