First, you have to have the cable(??) lines in your house checked for proper operation,(terminations, spiltters, couplers, etc). Cable Co(??) should be able to do this, or a friend who's knows electronics. Once this has been ruled out, goto your local Ham radio club, nearly everywhere USA has one, you should be able to help out on this matter. Local Radio Shack might shed light on contacts there.
Point is, he's probably a Ham radio operator. That being the case, he's causing cross-modulation interference in the TV IF circuits. Without knowing what channels are affected, I'll guess somewhere around channels 19-23.
That he's operating(radiating) a Ham radio, he's required by law to be licensed for the frequency ranges of his operation. And here's the biggie, if he gets a complaint from a neighbor about interference, he's required
BY LAW to eliminate the interference. Since you've already attempted to rectify the situation, you can contact the local Ham club, and let them identify/locate him, and deal with him. They will most likely take the FCC coordinator righ to his premises, and they will test his equiptment, and notify him accordingly, if he's legal that is. If he's not, he loses the equiptment, and is fined. Simple as that.
He's required by FCC 97.21 to limit his transmission to exclude certain times of the day, once notified of interference. He's further required by FCC 97.307 to reduce, or eliminate the offending transmissions as much as possible, (that means install traps in his equiptment, and these cost money!)
Those FCC subparts were found here:
http://www.access.gpo.gov/nara/cfr/waisidx_98/47cfr97_98.html as maintained NARA.
Print copies of both, and highlight the sections that pertain to your greivance, then approach him again, with a witness, such as a Deputy, and ask that he comply with the Law, duly notified. Ask the Deputy to notarize a statement that you've attemtpted to rectify by initial contact. If the guy fails to repair, goto FCC website
www.fcc.gov , and contact them about this matter. While they may only send the guy a notification, the wheels have started. Again goto local Ham clubs for assistance as well. Don't just sit there looking at the herringbone patter on your TV.
Good luck with this guy. I've had a similar runin with a fellow Hammer up the road, and I had a heck of a time with him, and after we reached an
understanding we're all happier now.
Best Regards,
Don
