TS820S Repair Questions

[Brian Carling]

Hi guys,

I have a newly acquired TS820S and the VFO is jumping
around pretty badly most of the time.

I also noticed that the "tumblers" for the 100 kHz positions
on the analog dial are not correct either.
They start coming out at 140 kHz instead of at 100 kHz.

The VFO jumping is a separate issue. At first I thought it was dirt switches - either
the function switch or band switch.
But then I noticed as I get higher up the dial, even the tuning dial
itself will cause it to suddenly jump from say 7160 kHz to 7885 kHz.

Does anyone have any ideas about where I might start looking for the problem so I
can fix it?

The rig was in storage for several years and prior to that had supposedly worked
just fine.

Any tips or pointers would be appreciated.

Thanks - Bry, AF4K
