Something from left field: Does the nose have any pattern to it? My UHF seems to have site noise that is possibly generated by a 2.4g digital spread spectrum controller. At first, it seemed like it was regular but I found that a TV stationg jput this system in at the same time I changed to a new repeater package and 2 bay half wave spaced UHF Comprod commercial dipole. Frustrating to say the least but just a thought.

First, the antenna and hard line is ok. We've tested that part out and its working. We think ( I ) that we got zapped through a unused phone line which is mounted behind the repeater rack. Yes, we have tested the can's using both a IRL (?sp) and a General Dynamics service monitor. They were taken apart and cleaned and retuned. Everything indicated they were functioning normally. Till we put them back in service. I don't know if they were tested with a dummy load. The technicians made many trips to the site: the technicians worked for the company that we rent the site from. We replaced all of the connectors and only found one that had scorched indications on it, but that was all. I asked if any of you knew how to find out if a can was operational, because all the test equipment that was used indicated they were ok. We finally found a workable solution. We added a fifth can, tuned to the transmit freq. That stoped the crackling noise. Now we're going to replace the can's, and go with a 6 can configuration. this is what was recommended by the technician. Rich K8JX www.w8usa.org
