Hi,
Also had that problem some years ago; as far as I remember the pot is
accessible from through the bottom cover. I also thought it might be
the pto, but researched the problem on line and found out about the
offset pot.

When I had my Corsair 2, I had a warble on a number of the HF bands. I
could clearly see it on PSK31 signals on the waterfall of MixW. I
rebuilt the PTO a number of times but it didn't cure the problem.
Eventually it was traced to a dirty preset pot which set an offset
voltage on those bands. I can't remember the component reference, but
- if I remember right - it was the only one on the board and sat up at
right angles to the board. A squirt of switch cleaner did the trick.
For you, this may be the cause of your problem. Anyway, if you can
find the offset pot, give it a squirt of switch cleaner and see what
happens!
