OT: TenTec Corsair problem

Julius Fazekas n2wn
Sorry about the space, but I know a few folks had the
TT Corsair (not II) before getting an Elecraft.

A friend has a problem with his rig. I suspect it is a
VFO/PTO problem. The last four digits on every band
jump all over the place, form the sounds of the audio,
the rig is running all over the frequency range of the
VFO/PTO. He doesn't have schematics for the rig, but I
would suspect either a bad voltage regulator or
clock/oscillator.  Any help?

Thanks,
Julius

The Corsair PTO, like that of many of the older the Tentec rigs, is
greased with some form of pig fat (not really)  which gets hard after a
few years and needs to be replaced.  Although you will hear otherwise,
the only correct way to do this is to remove the PTO, disassemble it,
clean the parts, regrease, and reassemble.  Tentec sells a kit to do
this for $25 which includes all the parts which can wear, the correct
grease, and instructions.

I am currently in the process of doing this to an Argonaut and I've done
a Corsair in the past.  It looks scary but is actually not so hard with
the instructions (you *do* need the instructions).

Good luck.
