I guess our definitions of manageable drift are different. 15 minutes is no big
deal, and if I'm in that much of a hurry, I just deal
house is around 70 degrees. Same holds true for the B-line. The PTOs just
seems to move around much slower when in the correct ambient temperature home.

I've got a DigiMax freq counter with an "oven". Now, DigiMax counters weren't
the greatest, they were made to be cheap - I wouldn

No disrespect was meant. :) I've looked at these gadgets, and don't find them
necessary. IMO a TR-7 that is drifting unmanageably is broken, and needs
repair. My interest is more to
This is pretty standard stuff in the FMT community. In my IC 751, which
have used in the FMT's, I simply placed a small styrofoam "box" around
the ref crystal. It is the temperature induced short term drift that is
the problem, not the absolute accuracy. I can measure where it really
is but

notice it as much.
No harm, no fowl. Just comments.

Nothing funnier than a bunch of SSB types sitting on 3975.00 MHz (or so they think!) and spend
hours fighting over who's transmitter is 150 Hz high, (or low,) when NONE of them are actually on
