It MAY interfere with the operation of the computer, if a transmitter is
nearby. Legal ham radio power levels (probably CB, too) can disturb
electronic equipment, including digital equipment. It makes sense if
you think about it: there are suddenly some weird signals on the bus
(any conductor can be an antenna) and the machine gets very confused.
Remember: if RF can get out, it can also get in! And vice versa. Leaky
RF can cause some very bizzarre problems in modern high-speed digital
equipment.
