I was first licensed in 1962 and when in the USAF in 1966 I had the base
commander's permission to operate an electronic entertainment system
repair business from my on base house. My main parts supplier was in
town 15 miles and an expensive long distance call away so I used CB to
talk to the supplier as well as to coordinate with two partners. A near
neighbor said nothing to me but turned in a formal interference
complaint stating I was jamming his TV with my CB. I got a letter from
the FCC and had to get a 2nd class radiotelephone licensee to
investigate and report via a form the FCC supplied. My equipment
checked out OK but upon checking the complainants TV it was found to be
a very old obsolete unit with an IF frequency in the 27 MHz band. I was
transmitting directly into his RF chain. I was not required to do
anything and the complainant could suffer the interference or get a
different TV. The 2nd class was a USAF officer who did the work pro bono
as he was a pilot and I was the instrument trainer operator/instructor
he came to for 2 hours per quarter.

We had a number of Statewide paging systems running and one of them was on 35.22MHZ (called P1). I was the Director of Operations at the time and we received an interference complaint from a person in Stockton that our signal was getting into their TV. This was unheard of because we'd never had any prior reports. My only tech (small company) was on vacation to I went and visited this complainant. Sure enough, it was our paging signal getting in to the TV. I asked the person if I could take their TV apart and see if there was something wrong inside. He allowed it and I found the coaxial cable from the tuner (IF out) was terminated at the motherboard with an RCA connector. The male RCA connector on the coax was pushed in just far enough that the center pin was holding it in but the shield was not connected at all. I pushed the RCA connector all the way in and the interference stopped. I put the TV back together and never heard from him again. Would you let a stranger come into your house and take your TV apart? True story.

There may be no correlation at all. If the times don't correlate, it definitely has nothing to do with you. That should be the first test. Note, however, than neither an alarm system nor a microwave oven are receivers for any frequency your transmitter could possibly be generating on 80. (OK, may the alarm system, but it's highly unlikely. Definitely not the microwave.) Technically, you have no responsibility at all. However, in the interest of neighbor relations, it's always best to try to help solve the problem. If the neighbors are cooperative, all it will cost you is a few ferrite cores and a little time. Some years ago, a neighbor's garage door mysteriously was opening itself. He asked me about it, and I checked my log, which showed no operation. He was satisfied with that, and got a new garage door opener. Never heard from him again. Not all neighbors are so reasonable. RF susceptibility used to be much more of a problem. Now most of the RFI is going the other direction. I had to buy a neighbor a new TV a couple years ago, in the interest of neighbor relations. So it goes. 73, Scott K9MA On 11/18/2019 19:25, john nistico wrote:Ok so my neighbor claims I am coming through the speaker of their alarm system. The other neighbor claims the microvave. I am running a Yaesu 5000 150 watts to an inverted v with the apex at 85 feet fed with hardline. This only happens when I am on 80 meters, 3705 is where I was when the first call came in.

I had an instance where a neighbor on the next road over came to our home claiming the antennas 9 Yagi antennas on 4 towers had captured all the TV signals in our area and her TV signal was almost just snow because of it. I and my wife listened to her complaint and I tried unsuccessfully to explain A: TV signals are not attracted to my antennas like a magnet B: the TV broadcast signals are not near the current commercial broadcast frequency’s ( to no avail ) I offered to come over to there home and examine there installation.Apon my arrival it was at first asseratained there home was notusing over the air broadcast TV BUT Cable TV !!!!In inspection in the basement the owner and son tried to becomecable TV distrabution engineeres.
