Cell phones, the weather, and the Atomic clock
Cell phones, the weather, and the Atomic clock
I received an Acurite brand weather station for Christmas last years (thanks Mom and Dad). It's the simple kind of thing that has a wireless outdoor temp probe, indoor temp, and syncs itself with the Atomic clock for accurate time via radio waves emitted from Denver. I like the thing, and I keep it in my bedroom since I'm very weather concious. The problem I have is that my roommates' cell phone, when he's getting an incoming ring, causes my weather station to make loud beeping noises which often wake me. It's not a big deal unless your rommmate's work schedule is about 6 hours earlier than yours, and he sometimes gets a couple calls before he he leaves the house. Anyone else ever had a cell phone set off some type of wireless gadget?

Guess he has Cingular? They run on a GSM network that interferes with radios. I have a coworker that runs Cingular (loud, obnoxious ringer aside
) and also has an old FM radio, about two seconds before he gets a call, his radio goes nuts if it's on.
Does your device have an alarm in it? I have one similar to yours that does, and I know there is no volume settings or anything. So I'd suggest opening it up and clipping the wires to the speaker. That is if you don't use the alarm at all. Usually you can shut the radio or whatever off and it's silent, but this I don't think "shuts off". Otherwise, tell roomie to switch carriers.

FYI about interference: GSM phones transmit data in bursts at 217 Hz (the base frequency is 850, 900, 1800 or 1900 MHz range, diff thing), which creates strong electromagnetic field modulated at 217 Hz, which in turn induces currents in surrounding conductors in audible range. You can sometimes hear it in your headphones if your phone is too close to your PC, call center reps who work as cellular customer care hear it every day 100 times a day when people call from landlines holding their cell close by (the bop - bop - bop - bop - bzzzzzzzzz sound). This is because some traces on the circut board of the landline phone are close to 1/4 of the wavelength of the broadcast frequency, thus becoming efficient antennae. Phone amp picks it up and amplifies it and you can hear it.
Just an FYI.

Thanks for the responses, I'm about to open the thing up and clip the wires to the speaker (great suggestion)...I don't need the noise. I just found it interesting that it even happens. I think my roommate does have Cingular, and I have Sprint, but my phone doesn't make the weather station go nuts.
computer speakers here and makes lines in my CRT computer monitor, Cingular/ATT, and when im at home it will actually mess up the TV signal, b.c my parents only have an antenna for free tv in the attic
