Yup... sounds familiar! In my case it was VHF, and also
about a mile away. The blips were pretty strong, but of
very short duration (and the scanner apparently never
stopped on that frequency!). That goodness for
PL/CTCSS/whatever-ya-prefer to call it...

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

Have cable leakage so bad on the input 449.750 it keys up the repeater a
lot, Even with the PL, I Deal with it during the day, But I have been
turning it off at night. It has been like this for two weeks unless it
rains. I
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.

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. T

Hi Ken,
Yes it is 1420 AM.
How do I remove it?
As soon as I put my mobile notch duplexer back in, the AM station was gone.
Thanks,
Jeff
