[AMRadio] OT - TS-440S question

[Larry Szendrei]

Thanks, Geoff. I'll be looking into it at my first convenience - today 
was spent on outside projects, as it was a perfectly spectacular day 
WX-wise here, and there was lots to do (still is!).

I got a response on the Kenwood list at qth.com from a guy who does 
Kenwood repair - he thinks the shaft/bushing has galled, and, 
unfortunately, I think he's right. He says I MAY be able to loosen it up 
by coaxing a drop or two of light machine oil between the shaft and 
bushing and working it. After removing the knob, of course.

Hope all is well with you, KA5SSY, and the harmonic.

73,
