That might be related to your squelch setting. I don’t have my G3 handy to check, but I believe you can adjust the squelch sensitivity.

Hello Paul and welcome to the Cow Audio Forum.

That sounds like an RF “hit” of some sort. Could be enough smart phones in the area or something else. Have you worked there before? Did you do a scan when you setup?

Getting closer to the transmitter helps, but I had a guy with a smart phone on his belt once and the transmiter a bit farther around his belt. Range went from 50-60 feet before I wired him up to a foot and a half.

Hi Eric

Hi John
My squelch is set to low

Should I change this. If it is set higher does that reduce the range of the signal?

Thanks

[Paul Mcdermott]

Hi Ty
I always scan the area before I set up the frequencies. Often I get these rf bursts half an hour into the filming, sometimes as really strong bursts and other times weak and then it might go away again.
I keep my phone switched off and try and keep a good ten feet away from people with phones on.

Yes, it’d probably affect the range as the signal needs to be stronger to punch through the squelch. But, it’d also be harder for the offending signal to punch through. I have no idea how much it’d affect the range. If you can get in that room to test, you can determine if the range is ok and if you still hear the interference.

I once worked a room in which I was having a monstrously bad time with my wireless. I found a facilities person and asked if they knew if there was anything on. They opened a closet and all the wireless transmitters had been left on. The church in which you shot may have the same thing going on.

Hi Ty
This has been the case a few times. At the moment in Ireland there is a change in the frequencies. I’m on the new allocation with my new G3 kit, hotels and churches tend to be still on the old frequencies or something totally different as they imported their kit from abroad.
For speeches alot of the time I have to attach my wireless mic to the hotels wireless mic, very messy.
Thanks for your input. I’m going to up my squelch and see how I go.
