Hello all, I am trying to help a friend with a problematic channel 7. Whatever is causing the issue is very strong & seems to be a direct co-channel issue. It is an intermittent issue as seen in
this video clip. I'm certain it is something inside the house as once we stretch a cable outside the house about 100 feet into the front yard, channel 7 is good. Just not sure what could be strong enough to interfere with such a strong RF 7 inside that house. RF channels 8, 9 11,12 & 13 are not affected at all, so this has me stumped. Tried trapping UHF & FM but makes no difference at all.
Any ideas, thanks!!
