Sennheiser G2 issues

I have been using a Sennheiser G2 wireless system for 2 years now. I had access to 2 sets in school where I shot 2 documentaries and many random interviews. I purchased one when I got out of school and have used it a couple of times with no issues. Now for the past 5 months at work I have used the same two systems EVERY OTHER day. I have logged HUNDREDS of hours with this system, and for the price and what it does, i love it.

That said, I was on location 2 weeks ago and had some minor interference issues on one of the systems. It was a really "white noise" type sound about 6 times in my 30 min shoot... One time I could almost here a voice with the white noise. I didn't have my headphones on at the time but when I heard it in post, I immediately changed the frequencies for the next day's shoot. The next day, it happened again, I changed the frequencies again and I am going to be watching the footage from the day after that this afternoon, so we will be seeing if it happens (in our studio where it has never happened before).

Has anyone had issues with these lavs? Should I keep experimenting with different frequencies, and is there a way for me to detect interference before I start shooting and hear it in the phones, having to cut and back track. I will try to put up some audible examples soon...

Thanks in advance for the help!

Cell phone interference? Was everyone's phone off (not on silent or vibrate)?

I believe there were cell phones that were on in the room yes. but the producer and myself always have ours on during shoots...
 
In our testing, cell phones have not typically interfered with Sennheiser wireless systems... however, it may be the low frequency range. It may be time to upgrade to the A Frequency block.

Cell phone, and especially Blackberry, interference with audio is well documented. Even non-wireless setups can be effected. Turn 'them puppies off ... unless you're an on-call trauma surgeon there's nothing so important that it can't wait on voicemail for a few minutes.
 
GSM cell phone interference would not create white noise, it would sound like beeping. It may be the location you were in, not the gear. If it is the gear it will do it anyplace.
