Any idea what's causing this audio problem? (see video attached)
Hi, thanks for helping - I've recently started having huge audio nightmares with my normally very trust EW100 G3 radio mics which I've used for many years.See this clip:
(near beginning at 01:08 are some of the worst bits)
There's horrendous noise at seemingly random points, sounds to me like massive inteference. Very hard to repair when it's over speech/ sound I want to keep.
I've just done a test now in my office and am completely unable to reproduce it, even if I tug at every part of receiver or transmitter units.
Camera was on tripod, everything carefully plugged in and not being touched.
I've had exactly the same issue on a recent shoot last month with these radios.
My only hypothesis is that 5G (which my phone doesn't have) is causing this.
Really appreciate any ideas and happy to report back any actions suggested for me to try. If you run the clip through Audacity, the free sound editing programme. you would see on the waveform where the problem is. Where the noise isn't over voice, you can substitute it with silence. Assuming you don't use Audacity, there is one of my tutorials on noise removal on Youtube, mainly clipping but the same principle applies, although for clipping you need to use Audacities Normalise function. I noticed the speaker was wearing a lavaliermike, maybe you should try a different mike? The picture shows clipping in Audacity.

Have you checked the batteries (particularly in the transmitter) to make sure it is delivering max power?
Also worth checking the receiver squelch level to ensure it is high enough to prevent unwanted breakthrough but not so high as to cut off your wanted transmission.
Have you tried using different frequencies?
Hope this may help. Good luck.
