First of all, you placed the microphone receiver in the worst spot, you could ever think of.
There are speakers just next to it. That means, there will be a lot of electromagnetic interference from the speaker coils. Move that station out of there, and all will be fine.
The reason why other station works, and that one not is in the shielding of the receiver.
Other one has better shielding, the speakers there still produce the same interference.
I use a two-mic wireless Gemini-brand unit into back of SC Live 4. No interference. My speakers spatially separated from unit. And the mic unit about 3 feet from Denon unit and inside DJ pop-up stand-shelf so also some solid structure between mic unit and SC Live 4.
It seems I was lucky with my other set up to not get any interference.
I bonded into position my mic reciever, my SoundSwitch mk1 interface, a quality usb hub, 2 mains adapters and all the cabling & my DJ controller into my flight case, with no problem! I can plug in a IEC lead to power everthing, 2 XLR speaker cables & a DMX cable, thats it - and I wanted to do the same with my Denon SC live 4 set up.
