So has anyone conducted tests to determine if it is a mixing problem ?

Portable sig gen into the repeater site and swing it about the place in various
locations , sort of a revrse hammer to the power poles
if it is coax introduced you quickly confirm your suspicions but if its ac
introduced or grounding or some other oddity it usually helps to eliminate the

I don't think so, Chuck. I work on Robins and traverse it pretty much from
end-to-end daily. I also have to traverse it quite a ways just to get off
How do the paging signals get to the three transmitters? Wireline? 72
MHz link? 930 MHz link?

1 is wireline, two are satellite.

How do
Yes, but odds are good you are dealing with three different problems -
similar mechanisms but different participants. Unless of course you can
hear it at all three sites on the same frequency.

Mike,
I'm coming to this late, but I have comments and questions.
What type of hardware are the paging transmitters? What are the
repeaters in question, and what type of duplexers, feedline, and
antennas are used?

on one of the transmitters you can control things a
bit.
Good luck hunting.

OK, this is probably not going to be an easy one.
I have seen several instances of mast-mounted TV preamps oscillating and
acting as miniature transmitters capable of sweeping over wide swaths of
spectrum
Laryn,
I don't 'think' there are any forgotten links, but I'll certainly ask the
question when I speak to the owner again. He's very open about his systems
and I believe he's very involved, but like any of us who is getting older,
it's possible he forgot something.
I agree about the spur
As mentioned finding the trigger both with and without the antenna would assist
with a solution , it could be very simple but you need to establish possible
triggers and monitor accordingly with the Spec unit
No guys. The signals on the INPUT are heard in many places around town. If
the signals are on the INPUT it ain't the ham equipment.
Aside from that, I've already stated that the hardline is 7/8 and the
antennas are DB-224.
