I have heard about video distribution amplifiers doing similar things, especially if the open connections are not terminated properly. (i.e. 50 ohm resistor/F-connector) A complex in southwest suburban Chicago area had the local police searching for several days before the ham found the source and disconnected it.

Re: [Repeater-Builder] OT - funny interference story
I finaly tracked down the .64 "Beast" after searching for 3+ years. My uncle broke down and drug out his IFR. It was a combination of a switch mode battery charger in a boat about 300 feet from the antenna to give me a perfect mix 600kHz off the transmit frequency, lower side band of course (still trying to figure that one out) that was so good that it would cause the repeater to occasionally feedback audio wise. Also some loose PL-259s on the capacitance stubs of the WP-639 duplexer causeing some desence after the inital problem was cured. Repeater was clocked at -121.5dB to open the squelch with no desense at 110W from the transmitter. Compare that to running at 5 watts to try to beat the mix and it still sounded like crap. Things are so good I am going to upgrade the antenna back to the station master clone after I rebuild it. Having proper test equipment makes all the difference in the world.On 1/12/06, Paul Finch <[EMAIL PROTECTED]> wrote: Jay,Nope, I thought there would be more on this message board that knew Walt, atleast his power supplies.

RE: [Repeater-Builder] OT - funny interference story
Hello, Another funny interference story, I may have put it on here before but it bears repeating. One of the Police repeaters in the area that the shop I worked for and maintained was getting a stable, slightly off-frequency signal modulated with a 1000 Hz tone but without CTCSS. It did not key up the repeater but interfered a lot with the HT's they were using. This had been going on for 2 or 3 days. The FCC was called and could not find it. The manager of the Water Department was a Ham and knew of another Ham that made a hobby of finding these problems. This guy had a van with a 22 element home made Yagi mounted on the top with a shaft going down into the cab, he used a pair of Vice Grips as a handle! Anyone know who this "Guy" is? He is also famous for the power supplies he builds. The Ham did what the FCC could not, he was able to see the direction of the signal from the Repeater Site. He took off in that direction with the FCC in tow. He located the building where it was coming from, the Motorola manufacturing facility in Fort Worth, Texas. The Guy took his portable tracking unit with the FCC man again in tow and entered the building. They introduced themselves to the receptionist, about one minute later 5 or so VP's appeared. The guy was then released to find the interference. They got to the room where it was coming from, there was a Cushman CE-3 turned up all the way (without the attenuator pad in-line) with a coax with the center conductor exposed and wrapped around a broom handle and pointed out the window directly toward the repeater site. Do you think some Motorola employee got a ticket sometime?

We met about 9:00 A.M. a few days later, at the entrance to the apartment building with the apartment Manager, the FCC Inspector, and the IFR. After contacting the residents that were still in the building (many had already left for work for the day), we went to the main electrical panel for the building and started shutting off circuit breakers to sections of the building. One breaker made the interfering signal go away, so that narrowed it down to just a few apartments on one upper floor.
