AND Bret, how did you solve this problem.  I have basic overload with 500
watts where the lights flicker and the TV audio jerks back and forth.  No
TVI.  Ideas?  The HD TV is going though a receiver for SS.

And after having built a few rigs with NO consideration about TVI, I would
not spend a lot of time shielding or worrying about out of band signals, I
never had a problem other than raw rf power getting into things.

If it chews up the phone, audio equipment, and 99% of TV interferance, its
just RF overload.

Funny, I can tune the FM radio in the kitchen by changing my TX frequency on
40 meters. The dipole is 30 feet above the radio which has a long wip
antenna on it....

I never had a situation where harmonics or some vhf/uhf stuff from the
transmitters was a problem.
