Electro-magnetic interference from an AT&T; cordless phone handset CL82301 charging in the charger when held and moved around near the internal Ferrite antenna on the back right of a 13-year-old boombox. The radio was set to 580 KHZ WIBW from Topeka. You can hear the station in and out as the signal from the phone waxes and wanes as I move it around the back of the radio. Recorded with Goldwave from line-in. You hear the signal to the base unit which is a low pulsed buzz, as well as the processor noise as it's charging. It's a single tone as opposed to the shifting tones when it's on standby.
