Kevin,

This sounds like a classic intermod problem. Does your
repeater and the new one each have a dual isolator on
its transmitter?
Yes, you will need a dual isolator on your repeater
transmitter as well as the new one 30 khz away.

Subject: Mastr II question

One of the systems I take care of uses a Mastr II in
station 
configruation as it's transmitter. Recently, a
repeater went on the air that is 30 KHz above our
operating frequency. If you are within about five
miles of our site and are monitoring on the new
machines frequency, you can hear our repeater. It is
not distorted, and it does not have any other
modulation on it. I have 
heard this signal on a number of differnet rigs, and
so have several other users, so I don't think it is a
problem with overload of my receiver or other problems
in my equipment.

I am not using the station receiver in the repeater,
but have an ICOM in it, as the only TX ICOM I had was
an EC version. I am using the RX ICOM just to provide
the conpensation signal to the TX element.

I had a similar problem about a year ago with a spur
60 KHz above our carrier, but it cleared up after I
swapped the exciter and PA boards out.

I have not yet been to the site to check out anything
yet, but just wondered if this is a problem anyone
else has seen. Thanks, and 73,

Kevin, K9HX
