Scumbria, My cell phone sits on my desk next to my monitor. I can tell when the phone is about to ring by the behavior of the screen. I always have about a 1 second warning of an incoming call. I think that this only happens with digital phones. This behavior does not happen with my wife's analog phone. ajb

Scumbria, off topic! I just tried the same thing with my cell phone, and I saw no effect on my monitor. However, I did notice a humming noise coming out of my speakers, perhaps due to the EM energy. By the way, my cell phone is a Nokia 6162, TDMA, on an AT&T call plan. My monitor is a high-quality ViewSonic PT770, so maybe that monitor is better shielded against EM radiation than yours.

Scumbria, When the phone is on in receive mode it should do this several times a second as it dialogs with the local group of cells that it is in range of. So when on and placed near the monitor you should see some recurring wiggles. When a call is in progress these wiggles are continuous.Shifting the plane of the phone should cause some pattern shift and make it run through various power levels, free fun for all. Ever try a hard drive magnet? It causes a visible effect from 3-4 feet and brought close can cause such a gaussing that you will need an AC degausser to make the monitor work convergently again as the internal power-on degausser is too weak.

Scumbria, your phone will also register with the cellular system every 4 mins. It's about a 1 second transmission. Digital modulation is very "noisy" on PC systems Milo

Scumbria, <I just saw something very scary. I was talking on the cell phone and working on the computer at the same time. I held the cell phone close to the monitor, and the screen started shaking violently. I did some more experiments and within 6 inches caused a very marked effect on the monitor's behavior. It gave me a feeling for how much electromagnetic radiation was being emitted from the antenna. Of course, this only works while there is a call in progress.> My phone doesn't seem to crate even minor disturbance on my monitor (Nokia 6xxx - GSM and Panasonic Panasync). But, nonetheless I have always wondered what the long term impact of these cell phones is. And, your experience makes me wonder even more... Chuck
