[TenTec] Corsair 2 not stable on receive, 20 meters

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!
