Actually, most transverters use the heterodyne principle to move frequencies
up or down, so the local oscillator in the transverter is the critical
frequency determining element. Still, 20 Hz off can make otherwise
good-sounding SSB audio (and the Orions are definitely capable of ESSB
quality audio with nothing more than a good mike like a Gold Line or PR-40!)
sound a bit "off".
Almost every night, I get on an informal, fast-break 'round-table' net on
3740 kHz with up to 10 stations using VOX or fast PTT. Anyone off frequency
stands out like a sore thumb and is politely asked to move onto the right
frequency. Nobody transmits for more than 5 seconds without listening for
comments or interjections, which is why we call it "The Short Attention Span
Radio Network"!

Subject: Re: [TenTec] Orion/O2 Drift Problem-who is interested in a fix?
here here! go check out a 'shack heater' tube rig, try 2khz of drift on
a good day :-D, 20hz is 'imperceptable' in comparison. though, i suppose
if you're operating through transverters then perhaps drift is more of a
problem.

to fight a 20 Hz drift?
Seems like you guys are brainstorming a lot of ways to spend excess
money when my solution would be to turn the radio on a little earlier.
I remember the days we used to have to chase people with drifting VFOs
and now we are worried about 20 Hz.
