Check my post of Mon Jan 9 21:06:12 UTC 2012 to see what I did using Bill Riches information where he described connected an internal pot. The new EFC pin 'floats' at 2.5V and 0-5V works fine to adjust the frequency slightly. -Arthur _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
