Quite true, the ear is powerful. But I'd like to see a zero beat
display - e.g., Lissajous plot of signal vs SPOT or even better, a
Fourier transform view that shows phase & freq centered on 0 Hz. Why
not have an auto zerobeat function? It's just a software problem. ;-)
With a little bit more work, you can have an SSB AFC so you don't have
to fiddle with RIT on nets. There are a lot of other useful features
still to be invented or implemented!
(Insert remark about open source community developed software being
the way to get crazy new features developed quickly.)
