It started 2 weeks ago. Satellite TV pixelation, sound stutter, screen briefly flashing to black. Lasted for hours but stopped late at night through late morning. Symptoms fit those of
interference. Nothing new in the house except a few LED lightbulbs (lightbulbs? really?).
A website that shows transmitters and antennas registered with the FCC (along with their GPS location) finds one within 3 miles. Across the street one house down only 200 feet away. Operates at 154 MHz. A zebra? Apparently you can fix interference with ferrite chokes clamped onto power cords and/or coax cables.
These are not expensive, but there are many different kinds, and you have to know the frequency you want to block and not block. [btw, they are subject to 25% tariffs as of 8 pm 9/30/25.] None of the ones on Amazon include the necessary specs, except inner diameter, and many reviews start with
"I wish I could leave no stars."
Then the interference, or whatever, stopped for a whole week.
Back again Sunday. Another website says the FCC license across the street expired in 2012. That is rental property. No way the same people are living there. I've wrapped some aluminum foil over some cables/cords, just for the heck of it. Shouldn't help, and doesn't, but when I touch it the TV responds. Is that a clue?
Nothing since Sunday. Something tells me this will just disappear and never happen again, but
only if I spend a lot of time fixing it. I've already wasted 2 days on this.
