I am working on a similar build with the same duplexer tuned by John at twowayradios. Tested it at 20ft up and I get about 600 yards. After 600 yards it is completely static then nothing come through. It was doing this same thing before I got the duplexer tuned (Didn't know I needed it tuned) and called twowayradios and they said send it to John to get tuned. However, now that I have the tuned duplexer the problem remains. I live in a fairly flat area and can get 2 miles on my handheld in the same area. Also sometimes the kg1000 will show a green transmit light after I have transmitted a couple times. Do I need to adjust dwell time? Is there something wrong with the duplexer or power source? Any help would be great.
