I built a serial port temp. sensor...
The unit uses DS1820 temp sensors and connects to the pc serial port.
There is a fifty foot run from the computer to the sensor.

My better half made me quit using it because of AM radio interference.
There is a constant beep beep beep.

Fortunately, the serial port has slew-rate limited signals and shouldn't be
an issue. The DS1820 (new ones are DS18S20) one-wire interface,
though, isn't so limited. If you use twisted pair wiring, and maybe a few
ferrite beads or 'clamp filter' units, it'll get better. To avoid ground
loops, ensure none of the distant end (sensor) wires touch any nearby
grounded metal.

OTOH... what the HELL are you doing letting your SWMBO listen to AM?

Get her a good "new age" channel on FM, and she'll get off your ass.G

I bought a Sanyo Internet radio last year. It is plugged into my
network router, and is on whenever I'm home.

Hi Michael,
I'm a big talk radio listener, is there talk radio stations available?
I also like science and tech programs.
