Well, I was playing around with cocoaModem a bit more, and decided to try to decode some of the HF-FAX images sent by the station here in Point Reyes. The quality isn’t quite what I would imagine it should be, and there were a number of sync issues, so I’m not sure what’s going on here. But here’s the very first image I decoded: the bar in the center is when I tried to shift it into DIGITAL mode on the FT-817, which didn’t work very well.
