Sounds like an open capacitor somewhere, either inside the EM supply module or external to it? The voltage-setting reference point should be DC. -- john, KE5FX _______________________________________________ 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.
