Hi. I have a 70cm repeater that has 2 Mastr II's, 1 for repeater, 1 for link. Several months ago, everything worked great. I pulled it offline several months ago and had it in my shop until a few days ago. I fired it back up, and both receviers are dead. I can inject a 11.2 MHz signal next to C303 and it will hear it. The only adjustment that can be seen are the ones at the start on C406, 411, and 416. I have looked at the preselctors, and they look fine. It did get humid in my shop this summer. Has anyone heard of this happening?
