What is mangled ??? -- the jack on the rig or the plug on a cable.

By jumper -- guess you mean CABLE that goes between the VFO and the TS-820S,

The jack on the rig is all pushed in and, well, mangled. I wish I could
publish a picture but no access. Actually, in the manual it shows a jumper
plug for the jack if there is nothing being used there i.e. vfo, amp, etc.
Thanks for the suggestion. Does Kenwood still service these? If so, there is
a service station right by the house. Even better, I will call them. Thank s
again.
