First, try toroids on the speaker leads. Probably need a higher quality
supply for the remote switch.

Subject: Hum Everywhere in my Shack
Hi, Folks. I seem to be having a grounding problem in my shack.
First, I've got a noisy wall wart that powers my network switch. It
effectively blanks out some of my 2-meter repeater freqs on my TMV710A.
Second, on the other end, when I transmit on VHF/UHF, I get a hum through my
PC's audio. The same thing sometimes happens on HF as well, particularly on
10 meters. Sometimes, I can hear my distorted self coming through on my
PC's desktop spekers.
Due to limited space, my PC and ham gear need to coexist on a 6-by 4-foot
desk. And neither wants to always play nice. Any suggestions that don't
involve a lot of moving and shoving would be helpful. Thanks in
advance.--Matt, N1IBB.
