 +====== Omni D Series C PTO Drift ======

 +//from the Ten-Tec reflector 8/17/12//

 +**W9ILF**:
 +I had a comment while on the CW traffic net 40 meters tonight that my tx was drifting up and down a little while transmitting on my Omni D series C.  I could also hear the freq shift in the receiver.  ​
 +
 +Anyway I finished with the net and moved down freq and had a QSO with a guy who said my signal was rock solid. ​ I called another net just a little later on 80 meters and my report again was solid, no drift. ​
 +
 +I guess it is intermittent,​ but where should I start looking to trouble shoot this issue?

 +**N4NT**:
 +Tune around some carriers and see if you can hear a warble as you tune. The
 +main cause of trouble like you experience has always for me been gummy,
 +dried-up grease in the PTO. I have never needed a PTO rebuild kit, just
 +clean off the gummy grease with Dawn or some such and re-grease. I asked a
 +tech down at Ten-Tec what grease they used and was told, "just axle grease
 +we get down at the Co-op."​
 +
 +
 +**W8AU**:
 +Take the bottom off, use cramolin or solvent on the bandswitches.
 +That clears if for my OMNI C
