SOLUTION FOUND!!

Hi everyone. After an extensive and exhausted search for the solution, I think I found one that works perfectly for me (maybe not for everyone).

Camera: Canon c100 MkII
Wireless mic: Sony UTX-B03 transmitter, URX P03 receiver
Connect: XLR

The problem: scratchy-static-digital-interference type noise that would not go away no matter the setting configuration on the microphone or camera. I even called Sony, B&H, and Canon customer service. B&H sent me replacement XLR cables of a different brand, but the problem persisted.

The solution: shooting at AVDHD 59.94p (instead of 29.97)
This helps me in two ways – I like shooting with a higher frame rate to get some slow-motion, and also it solved my noise issue!
I know not everyone likes to shoot at that high of a frame rate, but it works perfectly for me.

in the c100 MKII camera settings:

Menu > Other functions >AVCHD > Bit Rate > 28 Mbps LPCM

I hope this helps someone out there.
