Like others I suspect, my introduction to ham radio came via the pages
of Popular Electronics, the only "high tech" mag that graced the shelves
of the my local small town drugstore. As a young teen in the early
60s, my favorite features were the Novice hams I saw dutifully manning
their S-38s and Heathkits in Herb Brier's column - and reading the
latest electronic adventures of "Carl and Jerry".
My all-time favorite was a story titled "Extracurricular Education",
published in the July 1963 issue. The essence of the plot involves the
lads bad decision to go for a high-speed ride with a hot-roddin' friend
who ends up running the car off the road, trapping some of the occupants
inside the wrecked car with others incapacitated outside. Using their
knowledge of how spark ignitions work, Carl and Jerry manage to jury-rig
a spark transmitter using the ignition coil connected to a piece of wire
one of the victims managed to stretch out along the ground. Here's how
they made it work:
"Jerry was busy cutting a series of close-space notches through the
paint on the edge of the bottom of the dash. "When I drag the contact
wire across these notches" he said, "the rapid make-and-break of the
primary current will produce an almost continuous arc across the gap"
Very deliberately, over and over, Jerry brushed the wire along the dash
so as to spell out in slow International Morse:
"SOS SOS TRAPPED UNDER WRECKED CAR ON OLD RIVER ROAD"
Of course they were soon rescued and the hot rod pal apologized and
promised to mend his ways. But the kicker for me came in how their
emergency Morse message was intercepted - - a 13-year old boy watching
TV directly across the river who was studying for his ham ticket noticed
the interference flashing on his TV screen had a dot-dash pattern to it,
and called the sheriffs office. "That kid's going to have some
grateful help studying for his license, Jerry promised".
