I worked for the owner of a multiuser tower. The site manager was getting
many calls from an irate TV viewer complaining of interference on certain
channels. I called the complainant who sent me a diagram of amplifiers,
splitters, etc. A dozen boxes of spaghetti had nothing on this. The SM
offered to pay for basic cable, but the man felt that cable was cheating
people because it was supposed to be commercial free.

The SM was so frustrated he told me he would pay me a thousand dollars if I
could tell him which transmitter was causing the interference. The SM called
the guy and we arranged a time where he would be available at his TV by
phone and the SM had a cell in his car. From the description of the
interference I was confident it was a paging transmitter. I was looking
around and saw a 75 MHz (paging relays operate here) filter next to a
Quintron tx. The SM called the guy, I unplugged the Quintron, the problem
disappeared. I recalled hearing from a two-way tech that Quintrons played
well into a dummy load but had broad RF outputs that mixed with nearby
transmitters. This site had a lot of those. This was on a Wednesday. In
Saturday's mail was my check.
