An old topic, I remember this being discussed, but can't find my old notes. Anyone have a few hints or suggestions to slowing down the drift in my Ten Tec PTO? I have rebuilt it, the drift is over 1

I found that the drift in my Omni C was due to temperature changes on the varicap diodes used for RIT/XIT and band offset. They are in the circuit all the time even if the RIT/XIT is off. With these

THe acronym PTO stands for permeability tuned oscillator. That means it is a sliding slug in a coil that is responsible for the tuning of the VFO instead of a variable capacitor. THis method lends it

Actually, PTOs are more stable mechanically than oscillators that are capacitively tuned, and are preferred over the latter for mobile use. Properly designed, they have much less tendency to 'jump' f

For some newcomers and maybe others as well. I have several Ten Tec xcvrs newer than a Corsair II in use. However now and then its nice to bring up something older or different for a change of pace.

thanks for the info Lyle... I had the same problem with my 580 Delta... I used a couple of felt washers behind the main tuning dial and all has been well for a year... just added a little drag to the
