Electro-magnetic interference from a desktop computer, and an AT&T; cordless phone handset CL82301 when held near the internal Ferrite antenna on the back right of a 13-year-old boombox listening to the AM broadcast band. Recorded 2 years ago so I forget where I was listening. Recorded with Goldwave from line-in. You hear EMI from the computer at first, then I bring the phone on standby near the radio and you hear a series of nearly pure tones. The phone comes on and you hear a distorted dial tone. I move the phone away from the radio for a few seconds and you hear the computer again, then I bring the phone near and you hear a distorted busy signal. I disconnect and the phone continues sending to the base for a few seconds so you just hear a hum, then the idle tones are heard, then the computer noise as I remove the phone.
