How can a walkie talkie interfere with a speaker signal to immedatly restart a computer?

I use a Motorola Radius CP200 daily at work, when i sit down and push and hold the talk button near the speakers of my computer, the computer immediatly shutsdown and restarts causeing unknown errors inthe system logs. How is this Possible and what possible solutions are there?How can a walkie talkie interfere with a speaker signal to immedatly restart a computer?
Your speaker wires are acting like an antenna, and the RF energy is probably entering the computer and causing some problem with the electronics, causing the crash.



This can be caused by haviing the antenna too close to the computer, poor cable (poor shielding), poor grounding, and even poor computer or speaker design (makes them more susceptible to RF interference). It is not necessarily the radio's "fault", but it could be your computer equipment that is over-reacting to a little bit of RF somehow getting into it...



Remember, computers generate a lot of RF interference themselves, you can hear it over any AM radio close to the computer. Anything that generates RF, can also receive it (or react to it...)



Seperate the two devices, shorten the speaker wires, move the computer farther away from the antenna. You are using an outdoor antenna I hope... If it's inside, you are doomed to this interference almost no matter what.... If this is a handheld, you can only operate the radio away from the computer. I can cause almost any computer to crash with a handheld and 5W of power, if I move it around the computer, depending on frequency/band...How can a walkie talkie interfere with a speaker signal to immedatly restart a computer?
It's called Radio Frequency Interference (RFI). When the transmitter in your walkie-talkie is close to your computer, the wires in the computer can act as receiver antennas, and feed radio energy into critical components.



In the most severe case I've seen, a monitor burned out.



If you're sure it's your speakers, try moving them somewhere else. A couple of feet might make all the difference.



Better quality shielded computer cables might help, as might shielding or relocating the system unit (tower). But this is going to be a trial-and-error process. A self-contained computer such as a laptop might be more resistant to interference: no external cables except the power cord.



To attack the problem from the other end: use a plug-in headset / boom mic on your walkie-talkie when you're seated at your computer, and sit the walkie-talkie itself somewhere else. (Your belt holster might be far enough away.)



I hope this helps. Good luck.How can a walkie talkie interfere with a speaker signal to immedatly restart a computer?
when you use the radio, it creates a large electromagnetic radiation field which can force electrons to move in your computer. i would suspect that it is moving the electrons in the reset switch cable enough to make the system think that it has been depressed.



I use the same model at work and have never had that issue, but i have had it cause static on speakers, projectors to turn on, and fax machines to power cycle.
