More specifically, the MR 182 base station? Comtek doesn't have any documentation on their website, and a search turns up nothing useful. I'm looking for manuals and such. I got a call the other day about one of our six units acting up and sending a local radio station down the cable to the board. The radio lights up the VU meter on the unit itself. Tracked it down to our sixth unit, frequency is 185.425 MHz IIRC. Nothing on Shure's tracker showed up around there. Could this be a symptom of a ground coming loose inside the unit itself? I was hoping Andy would chime in here. Just looking for more trouble shooting ideas. The reciever worked fine, then had this issue for maybe two hours, before going back to normal. It's pretty old ('95 i believe), and I'm worried about it taking a dive again. Anyone have any ideas on what I should look for in troubleshooting? Thanks in advance. I also posted this over on the LAB, but wanted to get ideas from here too.
