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.

In the late 80s I worked for a paging company in Northern California. 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.

Ask your neighbors to note the time when these problems occur, then
compare with your log. 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.

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. So I can't figure it out nothing in
my house or any other houses is effected.

Great, Wayne! That’s exactly how to turn a potentially hostile
neighbor into a grateful one.

Ed,   This assumption that you antenna caused interference  is not
an unsual phenominum.  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 not
using over the air broadcast TV BUT Cable TV !!!!
   In inspection in the basement the owner and son tried to become
cable TV distrabution engineeres. Unseccesfully IMHO
After removing not 3 but 4    3 way spliters and 8  uncompleted un
crimped  connectors . After a trip to my home and returning with the
proper tools I reconfigured and  MESS and installed the  un fastened
ground  wire   at the entrance block.. WOW and  all read  SEVEN TV’s
and  one gaming console ??
Now   had a acceptable siginal

This happened during the height of the 2nd  Golf War and her husband
was in the service and in the Theater . As a VET  prompted me to go
above and beyond
GO figure

LOL....I had a similar instance....my beam is on a hazer on a 50 ft
tower..I could crank it up, and almost immediately get a call from my
one neighbor about interference to his tv, even though I wasn’t on the
air.....yet I could operate with it cranked down ( think closer to his
house !) and never hear a peep from him....

Don't assume you caused the interference. Twice in the past year I
have had
neighbors (over 2000 ft away from my antennas) claim I was
interfering with
their TV.  Both times I was out of the country...
