Hi, Johnny: I haven't tried it. I have worked with enough overtone oscillators enough to know they can be very cranky things if not set up right. The usual method involves putting an inductor in series with the crystal or a trimmer capacitor across it. Perhaps there are some engineers on the reflector here who can offer more specific advice.

-----Original Message----- Hi Ron, I am using XV144 with my IC7800. Therefore, it would be useful if I could fine tune the XV144. Is there any way to do it? 73 Johnny Siu VR2XMC _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
