This probably should have been the first test. If you can establish whether it's coming from inside or outside the house.

Btw why is he using two receivers?

Greg - Yes. I'm getting the intermittent bursts of static sounds on both receivers. One transmitter and receiver are almost brand new (purchased several months ago).

Pete - I'm using two receivers for two out of the three cameras that I'm using. (I don't have a 3rd receiver for the 3rd camera, at this time.)

Taking the wireless set-up out of the house is a good idea. I'll be doing this at a later date. In the meanwhile, I should be getting the new lavaliere microphone that'll be attached to the Zoom H6 audio recorder to get a good, clean sound without the annoying static sound that I'm getting (from the wireless lavaliere set-up). For the other two cameras, I'll just use the internal microphones for now.

Here's a photo of our "Green Room".

Ted, maybe this was implied in your answer, but you didn't specifically say so and it's an important detail. Are you getting the static hits on both receivers at the same instant?

ALSO is your range a combustion type (burning natural gas, propane, etc.)? If so, do the static hits coincide with using the electronic igniter on the burners?

Or is there no range involved (per your "green room" photo)? Somehow I imagined cooking would involve some source of heat, but then again I'm no cook.

Only one camera needs the wireless lav feed, other cameras can use their internal mics since their audio should only be used as a scratch track for syncing purposes.

The OP hasn't posted for two weeks now. Has anyone heard from him off-forum? I hope his disappearance indicates that he identified the problem and just didn't bother to get back to us. I'm curious what (if anything) he's found out.

Oh dear. . . My apologies! LOL!

I've been doing extra shifts at work. (I'm an ICU/CCU Staff Nurse and Per Diem Shift Supervisor for my hospital.) Work has been busy!! (Ugh!) Anyway. . . . an update. . .

The one test that I should do, but haven't done yet, is to take the pair of the wireless Sennheiser system outside, free from any kind of interference, and see if the problem persists. Although this particular set is nearly brand new, I simply might have a malfunctioning wireless lavaliere system.

The solution to ensure good sound?!?? I purchased a SONY ECM-77B lavaliere microphone and attach it, via a regular (extension) XLR cable, to my happy ZOOM H6 recording device. I get a good clean audio signal with none of that frustrating intermittent static sounds. The immediate problem is now solved!

Still. . . It would be nice to use the wireless lavaliere system. The new solution using the SONY lavaliere microphone works great when we video-record in our Green Room. (See one of my previous posts, here, for a photo of that room). But my loving wife wants the option of recording cooking videos in our downstairs kitchen. Having a "wired" lavaliere system could prove to be cumbersome. It would be nice to be able to use the wireless lavaliere system during any video-recording production outside the Green Room. So, I need to do some additional testing with the Sennheiser system. If it ends up being a malfunctioning system, I might consider purchasing a new wireless lavaliere system from a different manufacturer.

I wish to be clear about something. I am sincerely grateful for the time and expert advice that you all have shared here! Thank You All!!

Respectfully,

Ted

Swapping to a different manufacturer will only work if it is on frequencies that are different and interference free. Swapping to different banks on your current system could be just as effective.
