Need an antenna or some device to locate TV interference.
Interference is local and is within 600 feet of house.
Usually appears on Channels 2, 4, & 5. Somtimes on higher channels.
Appears on screen as electrical noise similar to car ignition noise.
I have detuned FM band to use as aviation band (108-136 MHZ).
Can hear noise on portable radio within aviation band.
Any help would be welcome as we have limited income and can not afford cable.

You'd probably be better off to use a regular broadcast band portable to find the
interference. Trying to use an FM radio will be difficult.

Now, if you had a radio scanner that could pick up AM modulation up in that
frequency range it would be even better.

Good luck tracking it down. It's most likely some power line interference coming
from a transformer or some defective insulators.

Had a similar occurence here late last year, the power company came around and
replaced a lot of equipment! But, the noise is gone, and it only took me a couple
of weeks to get it accomplished after the interference started.
