Has anyone replaced their microphone cable with an ethernet cable to eliminate RFI?

Do you have a problem with RFI on your mic?? I think/know there is some shielded CAT 5 or 6 cable, but don't know if it would help.

I would like to find a way to use a computer-type headset with mic, for portable operation.? I yet haven't started looking into the wiring of the mic and cable, though.? I think I'll start a thread about this, and see if we get any members who've tried something like this.? And hopefully have tried the cable for RFI, too!

Found something else.? Check this site -

One of his recommendations is ferrite beads on all cables, to reduce RFI.
The page is actually for a different radio, but they use the same mic.

Ferrite Beads

In order to prevent radio-frequency interference, all cables should be fitted with ferrite beads:

• Microphone cable
• Power cord
• CAT cable
• Head unit connection cable

(No head unit cable on our X5105, though)

There's also a mic modification to improve the voice quality.

Brian,

I read this somewhere about a year ago and, since that type of cable is shielded, it made sense.? I have not experienced any RFI on my OEM cable wanted to verify if I do.

Doug,

Haven't had any problem with RFI on mine.? I was looking at replacing my coiled cable with a flexible straight cable as I am not a fan of coiled cables.? Upon looking for some type of cable that would be a good replacement I came across an article about using CAT cable.? It may work but it's just not flexible enough.? Any ideas?
