RF interference from the HPX?

OK, after 3 consecutive one-man-band shoots where i couldn't get either of my sennhesier g2s to work, I finally realized that the HPX500 is creating some kind of RF issue that screws up the sennheisers.

Here's a quick rundown. I own multiple g2 wireless sets on both block A and C, this has occurred with both. I get to my shoot and scan for free frequencies, and i usually find around 4 per block. But then, when i power the hpx up I get a ton of interference on all channels. If i do a scan with the recievers mounted on the camera, I always get 0 free channels. Last night I had a little time to mess around before i went to hardwire, and I realized that if I get the receivers at least 3 feet away, I get free channels again. So wierd. I ended up putting them on my belt and running XLRs up to the camera, but that is not always ideal (for instance, last night I only had spare 50 foot cables, so I spent 7 hours with 100 feet of cable hanging of my hips. it sucked, and also I looked like an ass in front of my client and the celebrity I was shooting)

SO, this is a new occurence, it only started happening once i sent my camera to panny to have the WB fixed. Im wondering if they could have unshielded something that would cause such bad RF issues? any thoughts? has anyone else experienced this?
 
if it is possible, it is very wierd. Ive used my wirelesses with tons of different cameras, and never had an issue.
 
I too have the same problem. It has been driving me crazy. I also notice that if I wave my hand over the G2 receiver - it often gets interference too. I have had the WB fixed on my camera too. I am very curious as to what the problem is too. Please keep us advised. Thanks.
 
this is very interesting, i had similar experience.. walking arond in the same room i did get noise sometimes while moving, but going out to another room which wa 3-5 walls away,
didn't give any problems receiving the clean signal...
 
Interesting... We just did a 2 camera shoot, HVX200 and the HPX500 with a Sennheiser G2 on both cameras.. The hvx200 had no audio problems, The HPX500 would get an occasional rf hit, which I thought was due to the tall buildings next door that might have had antennas on them... When we staged the cameras last week in the studio, we had no problems at all with the G2's... The Hpx500 had the WB fixed before we purchased it.. This commentary gives me another thing to check out, thanks... As to the shoot, it was very pretty video and audio of a getto classroom, teachers and students.. Florescent lighting.. Amazing what these cameras can do.
 
Hi,

Why not contact the guys in the Panasonic Service and talk to them about it. They may have a concrete suggection for you. I would do this especially you had no problem before you send it in for the WB fix.

Best,

OK, it had stopped happening for a while, but it happened again today. Had to put my wireless recievers on xlrs at least 8 feet from the cam or I couldnt get a clear freq. Im going to call tech support.
