[TenTec] Corsair II PTO Problems

[hamradio at twcny.rr.com]

When I had my Omni-C, I noticed that when I put the rig on a specific 
frequency, it would not stay right on, I would move the vfo back and 
forth, but it would not stay put. I belive I sent the unit to TT and 
they repaired it but it was not cheap.
Is this that same problem that the group is discussing regarding CW?
Does TT still rebuilt them?
I belive that the rig which came after the Cosair II, (was it the Omni 
5?)
did not us the PTO?


thanks
