I’m getting a similar problem, also with the B range of frequencies on the G3s (I have 7 sets). But my problem is that when I scan sometimes there is nothing available. That is out of the 240 presets that get scanned!
It has to be a proximity thing because if I move 30′ the problem goes away and I get a typical 90% of the frequencies available but I don’t always have the luxury to change location so we have had to add some emergency hard wire microphones on live events. The other challenge is that once we did scan and lots were available but then something changed a few hours into our live webcast.
Is the B range (626-668 MHz) too busy and I should use the A or G range or should I switch to a different manufacturer?
