Have you killed each of your devices one at a time to localize it to a
device?
I would suspect ethernet noise.

Subject: [AFMUG] Interference on a repeater at 149 MHz
We have equipment located on to Towers one is a water tower the other is a
guyed110 foot tower. In both locations there are two way repeaters located
on the towers that are receiving interference from what appears to be our
equipment. Nothing is substantially common between the way the two towers
are built out. The water tower had all of the equipment on top of the tower
at one point and we have since moved all of our backhauls down to the
catwalk railing on the opposite side of the tower from the two-way repeater
attempting to put some distance between our equipment and the repeater but
has not solve the problem.
We have ePMP both 2.4 sectors and the 5 GHz Omni as well as some ubiquity
air fiber five and Power beam M5 radios on the water tower all running off
of net tonics 24 port switch and the microtik router. The other Tower has
only a few m5 radios and and M2 Omni. It also has an air fiber 5X amount of
lower on the Tower around 55 feet. Everything on this Tower has ethernet
cable's running to the base where our equipment is running from an old CMM
micro or their own power supplies in the case of the air fiber. Everything
at this Tower is located inside of a metal communications cabinet at the
base. In both locations we have removed old 900 FSK radios which were a
source of interference but the problem seems to have come back. I'm looking
for ideas on what others have found may be the source of interference or
solution because I'm tired of throwing darts blindfolded and hoping I find
the right Target.
