Does your cellphone cause serious interference to your car radio when it is near the radio and an incoming call begins?

Asked by davidbetterman (7555points) April 2nd, 2010

Because I have heard this happen many many times, and of course this indicates that when the phone receives a call, it generates a semi-powerful energy field within a half foot or so of the car radio.

No but for some very strange reason, at one place I worked it would pick up what I can only describe as fax machine noises when I talked on my cell phone sometimes. I could hear the screeching beeps but the person on the other end always said they didn’t hear it. It sounded exactly like a fax machine, but I have no idea how or why I’d pick up a fax signal mid conversation. It only happened at that one particular location. I also had a television once that used to pick up police radio chatter on a specific channel. I guess there are lots of waves in the air these days and the occasionally interfere with each other. It might have more to do with that than how powerful the energy field is. I’m not sure.

Was the TV cable or was this back in the olden daze when TV was received on rabbit ears?

As for the fax machine noises on your phone, you were being tapped…

It was an antennae but it wasn’t the olden days. I have lived without cable for most of my life. I could pick up abc, nbc, cbs, and the cops. LOL. I put my tv in the shed though. I don’t like tv all that much, which is why cable isn’t an investment I would make.

Yes. It will interfere with an AM radio and standard PA systems. No big deal.

Nope. The phone is digital and I usually use the radio in analogue mode. Even if I switch to digital radio (in the cities) it does not interfere. The only thing that it interferes with is my Skype FM handset and then only when the phone does it semi-regular handshake with the local tower – not when it is being used.

Yes, and it also interferes with your brain cells.

Lovely cancer. But who can live without their cell phone? “They” say they’re safe enough, so who’s to argue?

Actually I’ve heard this happen quite a bit. However, it happened with several speakers that were not connected to radios. I think it has to do with the speakers coils picking up the incoming GSM call signals. There are some initial signals that the cellphone tower and your phone use in order to locate your phone that are pretty powerful.

It doesn’t happen with my phone because it’s not GSM, but my dad’s old phone used to drive the speakers in his living room stereo and the PC’s speakers. It was quite unsettling but it was cool to know a call was coming a few seconds before it did.
