Drift is usually a fairly slow change in frequency, most often caused by
changes in temperature.
A sudden and abrupt shift in frequency, or "jump", is usually due to some
mechanical problem, like a loose connection or poor ground.
When the grease in the PTO becomes thick and gummy, the most obvious first
effect is a difficulty in making fine frequency adjustments, like
zero-beating an incoming signal.
These all have different cures, so the problem (drifty) requires explicit
definition.

Subject: [TenTec] Omni C help
Gentlemen,
I have a Omni C and recently I have been getting drifty reports on cw which
is all I use it for. Also, I hear the same drifty sigs on my end too on all
cw signals. When I tap the top or face of the rig nothing happens but if I
tap the tuning knob it shifts in freq. I have been told I need a pto
rebuild. Dont want to send it to TT because I don't want to put much money
in it but if the rebuild is all I need I will do that myself. Any ideas? TIA
and happy new year to all.
