Christopher, The only way is to open the oscillator up and reselect the capacitor they used to set it on frequency. I've done it once or twice long ago, not easy to do! I have a 1200 with the same problem however it does tune to 1Hz low so I use it as the offset oscillator for my DMTD unit! Cheers, Corby

Thanks, Corby. That was my guess. Is this cap buried in the styrofoam block? (Cue "we need to go deeper" meme.) -christopher 73 de AI6KG On Mon, Sep 19, 2016 at 10:18 AM, <cdelect@juno.com> wrote: > Christopher, > > The only way is to open the oscillator up and reselect the capacitor they > used to set it on frequency. > > I've done it once or twice long ago, not easy to do! > > I have a 1200 with the same problem however it does tune to 1Hz low so I > use it as the offset oscillator for my DMTD unit! > > Cheers, > > Corby > _______________________________________________ > 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. >

Hi Best guess: It’s inside the styrofoam block. It’s inside a sealed can in the block It’s (maybe) inside a can inside that one. It’s a SMT part on a board in that can. You set the frequency by pulling what they have there, measuring it and putting in another cap. If they used a series like 0.47 pf, 0.56 pf, 0.68 pf you may not have them on the shelf.
