If my memory is still working [chancy at best], "Madman Muntz" pioneered
the 21 MHz TV IF. Ranks right in there with the FCC's decision to 86
Channel 1, move the hams from 5 and 2 1/2 meters to 6 and 2 meters and
locate TV Ch 2 at 5 meters, putting the 2nd harmonic of 10 [and the 4th
harmonic of 20] in the middle of it. Having Ch 2 right next to 6m didn't
help that band much either.
You're fortunate the neighbor gave up

OK, gotta tell my favorite TVI tale: When I was a kid, my dad got a
TVI complaint from our next door neighbor in Maryland:
K3QDC: Are you sure it's me?
Neighbor: Yes, you said <X> and...
K3QDC: Yes, that was me!
Neighbor: ... and then he said <Y>.
K3QDC: Oh, I see. Ma'am, the fellow who said that is in Texas. Your TV
appears to be an excellent shortwave receiver.
This was on 15M AM and the TV in question had a 21 Mc. I.F.,
ubiquitous in those days. The neighbor gave up.

Circa 1958: Neighbor and TV Repairman came to my parent's door ...
"Your son's ham radio is interfering with my TV. Dad: "Our son

in the
closet." Long pause ... then TV guy, "Well his wire antenna is
still up
there and it's between my customer and Mt. Wilson, and it's
sucking all
the signal out of the air." Dad: "I'll ask him to take it down next
time he comes home." That didn't happen 'til maybe another year,
I had
a full time job at the local TV station at college and didn't get
home
very often. I did finally take it down, neighbor's TV still
didn't work
well, and he still blamed me.

> When I put my tower up 25 yrs ago my next door neighbor
complained of interference. I went over to his house to watch for
TVI while a ham friend was at my house keying the transmitter.
Suddenly a window started vibrating causing a buzzing sound. He
said “See, SEE!”. Just then his wife calls out from another room
“Honey, it’s just the dryer”.
