It is a delicate balance between finding the best frequencies, having the right antennas, adjusting the squelch. Without a spectrum analyzer, I would suggest you do it the hard way - once you get the antennas and squelch settings the best you can, every time you have an issue with a mic, write down what frequency it was set to (your bad frequency list) and use the ew100 receiver to find a new frequency. When you search for the new frequency, turn off that transmitter and make sure all the other transmitters are turned on. With intermittent interference, this may take some time, but I am thinking you will eventually find usable frequencies. I have a location where it looks to me like the very old and heavily rusted transformers on the telephone pole outside the auditorium are leaking a very wide band of rf noise, so I end up finding new frequencies for the 30 wireless mics about twice a year as the transformer ages and changes. And yes I have called the power company.....Anyone want to take a stab at this one?
Rack of six Sennheiser ew100 g4 A band with body packs. Never had a problem until December. Now, the whole rack is wonky. It’s not constant interference, but more like an FM trap at the end of people speaking, and not on just one mic, it jumps from mic to mic and even when the frequency changes. I didn’t believe it until I saw it. It doesn’t follow any pattern, it’s not better or worse depending on distance, and like I said, it doesn’t follow any pattern or is predictable.
Did some research and there’s an old analog tv station still broadcasting evangelist programs on channel 29 uhf, so that’s in my spectrum, but when we programmed the receivers away from that, we’re still getting it. Someone suggested that it’s a new cell tower that popped up, someone else suggested an exorcism. I’m just afraid the exorcist would come after me, not the mics.
Any thoughts?
