CB radio interference with USB devices on computer
 

I have a cheap CB radio from radio shack, but whenever I use it to talk, my
computer loses connection with one of its USB devices. I can even see the
pattern of what I am saying in the light flashing underneath my mouse. All
I have to do is unplug the USB device and plug it back in, but it gets a
little annoying crawling around underneath my computer. Is there any way to
make it -stop- doing this (besides the obvious solution of not having the
computer on at all).
Thanks.

You don't mention what kind of CB you are using. Is it a handheld
walkie-talkie type with a rubber duck type of antenna or is it a mobile
with an external antenna? If it is a walkie-talkie type with a rubber
duck antenna, you're probably out of luck and will need to just deal
with the interference to your USB plug or back further away from your
computer when you use it. If you have a mobile with an external
antenna, you may have a mistmatch (high SWR condition) or possibly some
feedline radiation going on. Try moving your coax further away from the
computer and see what happens.

Outside of shielding and/or bypassing on the inside of your USB mouse,
move your transmitter farther away. Even better don't talk on the
radio at the same time you use the computer. The USB cable itself is
fairly immune to EMI pickup but not 100% prevention. The circuit board
inside the mouse is often left unprotected. Then again most
manufacturers of USB mice do not intend the product to be used in
strong RF fields.

It's a mobile with an external antenna. It's right on top of my desk, where
my computer is, which is probably part of the problem. I'll try moving it
farther away and see what that does.
