[TenTec] Zerobeat & Radio Features - was O2 vs Orion

[Martin, AA6E]

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.)
