G-Squared, so KTNQ is probably causing interferences to my TV feeds

KTNQ runs at 1.02 MHz. KABC-DT is on CH 53 over 700MHz so it's
unlikely BUT with intense RF some VERY strange things can (and do)
happen. Both stations are FCC licensed so unless you can prove KTNQ is
doing something illegal (HIGHLY unlikely they are at all), there is
nothing to be done about it station wise and little you can personally
do. As always, good antennas with properly installed connectors and
grounding can help - sometimes a lot. 1MHz can get in ALL over the
place including baseband video and audio feeds in addition to causing
undesired non-linearities (cross modulation) in RF sections. I've
never heard of notch filtering AM out of TV RF feeds but it's possible
somebody makes such a gadget. Calling Doug Smith.........
