[TowerTalk] my KT34XA is high on 10-15m after cleaning contacts !!!

[Joe Clement]

The straps around the caps need to be very tight. You need bigger shim material.

Better yet go to m2 and get the upgrade kit for the kt36xa I have done 2 of
these, It will cure all the old xa tbl spots and work better.
