A couple of years ago I built a small FM transmitter that had a small microphone
on it. I could hear whispers in the room next door when I turned it on and tuned
in a small transister radio to its frequency. This may be an option.

I would be interested in any schematics you would be willing to give up, maybe even a little theory behind operation. I must admit I am lacking quite a bit in the communications area. Thanks, Joe Hoffmann E-Mail jhoffman@it.sait.ab.ca (...) (28 years ago, 4-Dec-98, to lugnet.robotics.handyboard)
