Re: [TenTec] Tuner (RF feedback or CM)

If you have feed line radiation with both a balun and cable isolator 
(coax isolator) in place you may have a faulty balun or isolator, or 
have them installed at a critical length for the band where you observe 
the feedback.
The most common feedline radiation problems I have seen have been Field 
Day stations, and a squeal in the rig audio, if you monitor its transmitter.
RF in the shack shows up as a shock or burn you get off a metal cabinet.
I doubt you have either one, if you don't know what to look for. 
Extreme high power cases are shockingly apparent! ;-)
