Thanks Nate,
I have read most all of the documents on RB and learned quite a bit about
repeaters and the GEs.

A word of caution may be in order since you are dealing with a club.
These days, the typical ham doesn't begin to comprehend the complexity of a
repeater system. To many, one simply needs to go out a purchase new
equipment, plug it all together, and it runs. Wrong!

I will go read that article. Thought I read them all, since January, trying to

That is when I decided to get into this repeater business. It has been a great

I'll chime in here and agree with Chuck's suggestion to try a little more

It sounds as if your PA is less spurious now than before, but you need to
dial it up more to eliminate all the spurious products. Solid state PAs,
especially mobiles, are noted for this when r

Thanks Tom,
The wind was calm today and knowing that the sections tend to work loose, we
screwed them together with sheet metal screws.
I would like to get a DB antenna but 700 bucks is not in our budget.

I'd suggest turning the power up more. You have it set at about 50% and the
transmitter may be intermittently spurious at that level.

Hi Tom,
I did crank up the power to 55 watts out of radio and that gives me 45 out of
the duplexer. Decided on this wattage until I can figure the problem better.
It is working better than before, but still having trouble.

Ok-
1. Where are you checking the swr at in the chain? Make sure you bypass the
duplexers to check the antenna, the cans can throw off the reading on some
meters like you describe using. If you are less than 1.5:1 I would not worry
too much more about it, any reflected power will get eaten up b
I agree with Ken. You simply cannot run a 100w GE Master II at low power,
spurs everywhere. If you need to run lower power, find a lower power unit
or throw an attenuator in line.

Like you said guess it was only a problem from running too little of power.
