Probably the outer traps on the driven element are zapped. The sleeve will
come off with the proper amount of applied force, and the coils are easy to
wind. I used denatured alcohol to clean the carbon off the plastic coil
forms before re-winding mine.

Subject: [TowerTalk] TH-3JR
Hi
Just got a used TH-3JR assembled and tuned for phone according to the
manual. It is fine on 10M and 20M but SWR is sky high on 15M. I checked the
joints and cleaned them to make sure there was good contact but still no
resonant point on the band that I can find.
Any suggestions to what to try next?? I'll have a look at the traps tomorrow
and see if there is anything obvious.
Thanks
Richard
