Harold - I thought I was the only one who did the buzzer thing!
I used a key & buzzer from a Morse Code learning/practice set,
ran a wire from one side of the buzzer up a tree and my friend could
hear me on his dad's CB radio a few houses away.
The battery I was using ran down so I hooked the buzzer to
household AC, it exploded and caught fire and I've been in electronics
ever since.
