A buddy of mine and I had some buzzers that were used as signaling devices
on the city busses. We discovered that when we activated them they played
hell with an AM radio. We decided that if we hooked a bunch of wire to each
terminal of the buzzer contacts we might be able to send messages between
our houses. He lived four doors down. Armed with the buzzers and a couple of
Philco radios we were in business.

Seems we had rediscovered spark gap transmitters much to the consternation
of the neighbors. All went well until our neighbor six doors down, John
Cummings W8DSL, took umbrage to our mode of transmission. Seems he could
read code even better then we could and soon ferreted us out.

For a couple of ten year olds it was a lot of fun messing up Stella Dallas
et al that our moms listened to.

Question to the younger crowd ... Why did I have TVI?

Cecil, you should not answer. But, I suspect you had the same
experience. Note: Cecil and I both have formal technical training.


Back around 1954, I put 600 feet of copperweld in the air,
fed by a modified ART-13 running 500 watts. The lights
in my room would dim during key down.

The closest TV transmitter was 90 miles away in Houston.
Madisonville, TX had no TV cable system at the time. When
I fired up, I wiped out TV reception for a good 100 square
miles. My parents took the ART-13 away from me, made me take
down the 600 ft. random wire, and go back to my 40w Globe
Scout and 40m dipole. :-(

I also came through rather distorted on a local church's
sound system. Some of the congregation thought that God
was speaking to them in an unknown tongue. :-)
