In my office we often experience instances of a "galloping" sort of buzz
periodically coming from the PC speakers near co-workers who have Cingular
GSM cell phones. A preliminary Web search turns up many instances of this
problem. My understanding is that these phones periodically communicate
with the network, and during these brief bursts the carrier is modulated
at around 200 Hz resulting is a clear, repeatable buzz pattern. How is
this buzz getting into the PC speaker amplifier, and, more importantly,
how can it be prevented?

GSM is your problem. Find a cell company that doesn't use the GSM standard,
and you problems will go away; and just maybe the honey bees will survive...

GSM is junk, and should have never seen the light-of-day. The wife's phone
uses GSM, and it interferes with EVERYTHING. Any speaker in the house
buzzes, doesn't matter what it's connected to, screws up the picture on the
TV, computer monitor, etc. Causes all kinds of interference to nearly every
radio in the house (communication or otherwise).

Thankfully my cell carrier uses CDMA, and I don't have ANY of these types of
issues, or any others for that matter. To top it off, I can use my phone in
MANY locations that hers will not work.
