[TenTec] Triton IV PTO warble

[g p <n2wjw@yahoo.com>]

Had a few of these in the past but I have never encountered a warble and of 
course it is more pronounced on CW even when not touching the tuning knob, in 
other words I can tune in to a station, leave it there and the warble just goes 
on and on, there is no drift and the tuning is very smooth. 
 
I have not gone inside the rig yet but before doing any surgery on it I was 
planning on tightening the boards first.
 
Any input on this appreciated.
 
Thanks, Gil
