I know its been a long time since I first posed the question on what might be causing the noise we were experiencing after being hit by lightening. After many trips to the Technical shop for testing, we replaced the repeater ( was a vertex 5000, now a Icom ur2000) and are in process of checking out controllers. The duplexers were my big worry. And yes, it would seem that concern wasn't unfounded. We started experiencing a degradation on the receive side of the repeater and then, a leakage from the cans. We had the duplexers checked out with two different service monitors and found nothing! The technician who works on duplexers took ours apart and found only a little bit of carbon, but that was it. they checked out ok. We put them back into service and the noise was there making communications impossible. We are now going to replace them with a 6 configuration instead of the four we have been using. My question to the list is, besides the noise factor and crackling noise, is there any other methode of discovering if the can's are bad or not? Yes, I did and have been losing sleep over this one.
I also wish to thank Kevin and the group for all their feedback on my question I put in last summer. You helped more than you know. Rich Ranta K8JX www.w8usa.org
