Very Interesting Mark , I know that in the past I recall vaugely that I
have came accross some sort of oscillation that can be picked up on a
particular frequency but the distance you mentioned is something that
each of us can probably came across this some time or another.

Whew after nearly a year of interference to my uhf amateur radio
repeater I found the problem. Turned out to be a Uniden scanner more
than a mile away from repeater site! The local oscillator for
channel 7 in the scanner was right on frequency for the repeaters
input and was tripping the
Have you considered adding a CTCSS decoder to your repeater? It
won't hide the problem ... but you hopefully won't go insane in
the process.

around?
Outputs on UHF here are on the high end! (GRIN...

LOL! Good one!
When did the FCC 'flip' the 450-512 MHz bands? ;-P

Jeff,
Please advise the make and model of your repeater, and its operating
frequencies.
A local repeater once had a similar problem, wherein an AM station's
104th harmonic was beating with the UHF MICOR's exciter output (which is
at VHF) and was then slope-detected by the repeater's receiver.
