Headset System
We have an FM radio station coming through our Clearcom headset system. Below is what we have tried.
We checked all connections and fixed the few connections that needed to be fixed.
We pulled the each station one at a time out of the system in hopes of finding the culprit.
Once every station except for one was disconnected and we still had the radio we pulled that
station and went to another station in case our test station was the culprit and it was not.
We tried grounding the three matrix units together then to a water pipe ground.
We lifted the AC ground.
We lifted pin #1
We switched the plugging in the power supplies to rule them out.
We tried many different mic cables. We tried different brands of mic cables.
We tried Clearcom belt packs series 500, 600, and a very early metal boxed model. Tried Production Advantage belt packs.
Took the power supplies out of the rack then moved the power supply away from the rack, plugged the power supply in and connected one belt pack, headset to it. In other words, it was one power supply and one belt pack and one headset. Then tried a different cable, belt pack, and headset. Tried a different AC circuit that had its circuit in the sound booth (nowhere near when it had been circuited.)
Tried a brand new power supply which was also a new model with one belt pack, cable, and headset and switched the belt pack, cable and headset.
Called the radio station and they were a bit baffled but offered to come over and see if they can come up with a solution.
Plugged the power supply though and APC with just one belt pack, one cable, and one headset. Then unplugged the AC power so the power supply was now operating on the battery backup only (it was no longer running on true AC electricity.)
Tried to put an active DI in line(I know crazy idea but grasping at straws.)
Took the power supply over to the a nearby building and plugged it into their electricity with one belt pack, one cable and one headset and we replicated the problem.
October 17, 2016 Engineer from radio station came over and tried toriods. No success. Showed us the radio stations antenna which is about 200 yards away.
