It's very possible that the PA has gone spurious. It's
also possible that you are experiencing intermodulation. Does the
interference always occur when the paging company keys up, or only
sometimes when they are keyed up? My point is, does some other
transmitter have to be on the air (or off
They need to put a band pass filter on the thing. I have had the 900 MHz
guys raising the noise floor over 100 MHz from their signal. If they put
in a good TX/RX or other BANDPASS cavity, they will be good (unless your
on 900 as well)

Back in the mid 90's, I contracted to a company in the greater
Portland, Oregon area recrystalling their and customers pagers.
The most I did in one day including testing them was 129, April 16,
1997.
I would want to believe that may prove your theory somewhat
Yes very interesting when you crunch the numbers:
129 pagers a day, 5 working days a week, 250,000 customers on a frequency for a large paging company equals 388 weeks or 7 1/2 years. Yes, I would say that it would be logistically impossible.
You must be a salesman..

No, I am not a salesman, but a technician who prefers
Coy,
You did not say anything about what receiver frequency
you are using that is getting hit by the 900 mhz
transmitter. Do you have a bandpass cavity on your
receiver? If you are using a BpBr type of duplexer,
then it has almost no rejection to the 900 Mhz signal.
You will need a bandpass
Does any one have any info on the possible problems with noisy
Motorola Nucleus II 900 mhz transmitters? A paging company coo-
locatde at the site with my repeater has one that's driving me up
the wall. I have been working with them for 3 months now, to get it
fixed. They recently changed
