I have a RAZR V3 from Motorola, with Cingular service. I've noticed that if I lay my phone down by my clock radio, or my PC printer, I get an occasional burst of morse code over my cell phone speaker, lasting just a couple of seconds - maybe 8 or 10 characters. It doesn't happen a few feet away from those places. Overnight, I've heard it about 4 or 5 times. The cell is a GSM, using 850 and 1900 MHz (so the book says). Anyone know what that's all about?
