I just got a Motorola v551 phone. For some reason, my computer
speakers are picking up some odd interference every hour or so
from the phone. The interference comes out as a series of
crackles, maybe 5-6 crackles. The same thing happens when I
boot up the phone. Granted my speakers are about 4 years old
(cheapo Altec Lansing 340 from Dell purchase) but I have
never had this problem.

Does anyone know what's going on? I never had this problem
with my old Motorola StarTac on Sprint.

Your speakers are detecting data bursts from the phone.
GSM data bursts are at 217 Hz which is in the range of human hearing.
You did not hear them before because Sprint uses CDMA - entirely different
signalling.

Thanks for the info. So I take it the problem is with my
speakers? Certainly they are decrepit (low-end model from
2001), but I don't think that that should be an issue.

No, there's nothing wrong with your speakers. Mine pick up the same thing
and there's nothing wrong with them. I also get the intereference, just
before my phone rings.

I think there is indeed something wrong somewhere. My
speakers are supposedly shielded from interference.
Whether my v551 is emitting illegal signals or the
speakers are sub-standard, there is something wrong.
The hourly crackling interference is extremely annoying
(particularly with that movie "white Noise" coming out...
yikes!).

I think this is the only really annoying thing I've run into since
switching to Cingular a couple months ago. I get the same thing. I meant
to post about it as well. I don't think you can blame the speakers since I
hear it on my office speakers, my living room equipment, and my car stereo.
All, while not top of the line, are decent systems and in excellent shape I
don't know if it's the v551 that has an issue, or if it is indeed something
unavoidable with GSM.

Typically "shielded" speakers are designed to prevent excess magnetism
from affecting nearby CRT's and other devices sensitive to magnetic
fields. This is entirely a different issue ... and one which had been
predicted in the early days of GSM implementation in the US.

Thanks for the info.

If anyone else with Cingular has a phone that's not
the Motorola v551, could you tell us if you get the
hourly crackling noise interference on your speakers.

By the way, which model cell phone do you have? Do you hear the
interference on a periodic basis (e.g. every hour)?

Archived from groups: alt.cellular.cingular (More info?)

The noise coming through the speakers is due to the GSM signalling,
particularly on 850mhz systems. When the phone is transmitting, your
speakers act as an antenna of sorts and pick up the buzz.

Just keep your phone farther away from the speakers. Nothing wrong with the
phone or speakers.

You'll get it with any GSM phone, including my Sony Ericsson Z600.

That's probably the periodic re-registration of the phone with the tower.

It ain't the speakers - it's the wires connecting the speakers to the
amp equipment that pick up the interference. My remedy was to use
coaxial cables for the speaker wires. Aside from that, the only other
thing that can be done is physical separation of more than a few feet.
Most cell phone wired headsets have a filter circuit embedded in the
headset jack and blue tooth headsets don't need it.

Jer - you are absolutely right, it's the unshielded
audio wire that's causing the problem. I have a thick
cable coming from my subwoofer up the front side of my
desk to the satellite speakers. Last night when I
put down my new cell phone prior to going to bed, I
positioned it right next to the cable. Thanks for the
insight. Interestingly, the cable is shielded enough
such that I don't get any usual interference from
my CPU case. Guess the GSM signal must be stronger.

I have a siemens sl56 (not cheap) and a panasonic gd55 which makes the exact
same 3 popping noises in the car and on 3 different computers. Co-workers
with gsm all do the same with their phones. It is a GSM quirk but it lets
you know before it rings you are getting a call. Funny to watch someones
face as you reach down and answer your phone before it vibes or rings!
Everytime I hear that noise i reach for my phone now without realizing it.

I have a Motorola V551 now and I get this same buzzing noise although it
doesn't seem to be as bad as my previous phones which were a Sony Ericsson
T68i and a Sony Ericsson T226. The Sony's would buzz my car stereo, the
speaker phone in my companie's conference room and other speakers it
happened to be nearby. It will reliably do it prior to recieving a call
(which is fun in the conference room because I know a call is coming in
before the phone rings) as well as in specific locations where I suspect the
buzzing occurs due to tower hand-off. By the way, it would do this on ATT
service or Cingular service.
