Yeah, mine has been off 20-30 Hz since I got it a few years ago. Now
that I adjusted it I don't expect it to drift.

Telamon:
How did the adjustment go? What frequency did you center on ? (it's not
exactly off by the same amount at 3 MHz as it is at 5 MHz)

It went OK. Zero beat on 5, 10 and 15 MHz. Before adjustment it must
have been right on the edge between 20 and 30 Hz off.

I also tweaked the RX-340, which was about 5 Hz low when warmed up. It
drifts around a bit when you first turn it on. Now it's 1 or 2 Hz low
when cold and about 1 Hz high when hot. The Drake stays a little warm
even when turned off so it does not drift at all that I can hear.
