Well, here we were, middle of the second show of the weekend. Last nights show wasn't great because the frequencies were overlapping some, it's a new school, it's something I hadn't gotten to yet. So I come in today and the sound guy and I changed all the frequecies so they work perfect. By this time everything was flawless, we could pick up the mic from anywhere in the venue, within reason. Well we get to about 5 minutes before show and I hear this over the radio "Mike, get up here NOW". I go up and every mic is dead, just plain dead. Dead as in the reciever is picking up absolutely nothing from the transmitter. The transitters were in the same places they were before where we got 3/4 strength for the signal. During intermission we set the frequencies to a different set. No luck, so we hurry our butts up and change them back to the defaults. No luck. So we just said screw it and set up more floor mics and other random wired mics. So what the hell is going one here? How can they work before the show and not during. Also, they weren't working when I left tonight either. This is $12k in wireless mics, so they just dicide to take a crap? Or is there something else going on? We had another AKG wireless mic that was VHF running along with this system and it was fine. Another thing was that you would only get so far from the reciever it would just drop out. The signal wouldn't fade out or anything, just be fine and then cut out when you got so far. Let me set the scene for you. There was a awfully big rain storm moving in during the show. Most of the government communications around here are VHF or low-band. The building is wireless with 802.11G, but that's always on. The city has a wireless network covering the whole town for all the city building around town, but that is also always on. All the HVAC and other random controls for the building are wired, as far as I know. The radios we were using are FRS/GMRS. The Telex intercom system runs over UHF, but nobody was on it and the base station was on before when we had everything working too. Any help would be GREATLY appriciated.
