John Thanks again I am calling it a night. Will let it soak over night and continue tests in the morning. Does any one have the oscillator circuit. With the connector on the bottom left to the right id something that looks like an adjustment screw,flat round flush with the surface and a screwdriver slot. Will not touch it unless I know what it is. Thanks again Bert Kehren Miami In a message dated 8/9/2012 8:58:36 P.M. Eastern Daylight Time, [email protected] writes:

If not, it sounds like the oven controller may be stuck on, overheating the crystal. I'd look into that possibility sooner rather than later. -- john, KE5FX www.miles.io _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
