Reddit reviews Gino UF35B 5mm Inner Diameter Black Core Ferrite Cable Clip 10 Pcs

I've seen lots of strange things happen during HF transmission. This doesn't mean the transmission is biologically dangerous, but it does show that many electronic devices are vulnerable to interference. Audio systems are likely to get some interference as are many microprocessor-operated devices. I have an antenna over the house and use a 100W iCom 7000. It gets into my stereo system (just a little), into my computer mouse (only a wired one, wireless is ok), my automatic outdoor light (it comes on when I transmit), my kitchen radio (a little), an older kitchen TV (CRT with digital adapter).

Sometimes you can cure the problem with ferrite beads on the cables to audio systems, including power cords. These have worked for me: http://www.amazon.com/Gino-UF35B-Inner-Diameter-Ferrite/dp/B007Q94CZM/ref=sr_1_1?ie=UTF8&qid=1426442564&sr=8-1&keywords=ferrite+beads

Well, if there is a loose connection or a solder pad thats peeled a bit that could be the cause. Its really doubtful it is an EMI issue in all honesty. One thing you can try is to put a ferrite bead on the cable close to the usb connector: http://www.amazon.com/Gino-UF35B-Inner-Diameter-Ferrite/dp/B007Q94CZM/ref=sr_1_1?ie=UTF8&qid=1411065808&sr=8-1&keywords=ferrite+bead if that doesn't help it is highly unlikely there is an EMI issue.

Is it the laptop itself or the laptop power cable? If it is the cable you could try a ferrite filter. One type looks like this:

Moving the antenna away from the interference is something to try. You might have to get an extension cable and adapter to do this if the cable on the antenna is short.

What cables are you using, as this is starting to sound like the speakers themselves are accepting the interference.

Are you using 1/4" TRS to same or XLR cables from the UR22 to the speakers?

I wonder if putting an RF Choke on the Laptop power lead and/or Speaker power cables would help.
