Not much, only a few htz, but ragged and disconcerting after so many

since I considder myself a a repairman, what do I do next? 30 or 40
years of "freezemist" and " "heat gun" analysis, I still don't know my
way around this Kenwood TS-130. (my first transciever).

Replace all electrolytics and see what happens next?

Scott's suggestion is a good one but I'd also suggest you consider
checking that the PLL isn't simply on the limit of lock. It doesn't
sound like you've checked the radio over since new and, with the ageing
of components etc., it is quite possible things are not as they should be.

I've done a quick Google and there are copies of the Service Manual on
the internet and Kenwood manuals are pretty good. You should be able to
make the adjustments.
