As I have said before TVI is TV INTERFERENCE due to HARMONICS. You
need a low pass filter for that or a good tuning. If you are having
flat out AM rectification audio problems, it ain't gonna work. RF out
is RF out. I had feedline problems in the immediate vicinity of the
gear in question. RF rectification problems stayed there, kinda as
expected. I even brought a spectrum analyzer in to sort it out. My RF
was clean as a whistle. Cleaner than a "stock CB". Regardless of
power there is a blanketing area for broadcast applications. Cleaning
up the RF audio is a good step too. Audio distortion is allowed to
become funky modulation (audio crossover distortion is ugly at an RF
level), unlike pro broadcast where clipper limiting is used. Granted
"CB" limiters suck but limiting of some sort should be used. I had an
old Invonics in front of my now declared POS Galaxy (FCC accepted)
Radio. With the limiter "clipped" and it was nice. I DID NOT MODULATE
OFVER 100%, but I kept it there

Could you elaborate more on the issues you are having? Maybe you have a
"working antenna" but the stuff interfered with is working too well as
a receive antenna. it can and does happen at all levels of radio, even
the best pros. You may be clean, the other stuff may not.
