In the waterfall, it's about 600hZ wide and sounds like a bunch of birds on speed. It was on 14073 today approx 1200z. Someone posted a site that had sample sounds and their mode names. Would you pos

ALE (the FED-STD-1045 version at least) sounds a bit like a turkey gobbling, only with a higher pitch. It consists of 8-ary FSK using 750, 1000, 1250, 1500, 1750, 2000, 2250, and 2500 Hz tones. Occup

From KE1JF's wav file, it is Multi-toned FSK of some sort, close to 400 Hz wide I took a look at the bins in cocoaModem's MFSK16 tuning indicator and see this: The separation of the tones is wider th

OK, I resampled that Alfred Hitchcock (Birds, get it? :-) sound clip from Bill (actually from Tom) by a factor of two, and it has the same structure as MFSK16. I.e., when resampled by 2, it has the s
