On the duplexers the specs state I should have about 1.5 db loss on the TX port... I just measured the power output into a dummy load. from just the TX'er. it is set back to 30watts out..
I then hooked the duplexers back up and measured again. I have 12 watts into the same dummy load.. with little over 3db loss I am thinking the cans were touched at one point another. I had workers up at the site and since then the repeater has not been working to good.. this is the reason for my Question about the desense..
