OK not sure if this goes here or on the Mastr II and/or GE list figured I'd
try here first though. . . .

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.

Thanks for your thoughts, John. I have not pursued intermod as
a potential cause of this problem because there is not any other
audio present on the signal head 30KHz away from our carrier
frequency, and the offending signal is always present when our
system is keyed up. There are not isolators on

I have converted a few to 6 meters,the transmitters were no
problem.However,I had to mod the helicals in two of them to get
acceptable sensitivity at 52mhz. This involved removing the first two
helical coils and shorting two turns at the top. You will need heavy
duty soldering heat!

The main problem to watch for is heat/swr issues on the PA as it

would de-rate the PA by a bit to protect it if it is going to be on a

Kevin;
I would watch the voltage feed to the PA as just as important as
the specific power level.. The GE power Supply idles high ~15v but drops
into the lower 12.x volts under full load, you can watch it load down as
you increase power.
An Astron RS50 for instance may be set

I'm looking at converting to a 6m repeater. I don't see anything
specific to the LB models on the RBTIP web site, unless I'm missing it.
This leads me to believe that other than replacing the crystals and
tuning it up, there
