It's about time for
another bunch of technical-themed comics from my vintage electronics magazines.
These four are from a 1940 issue of Radio News. With many of them (these
and others - see huge list of links at the bottom), you might need to have a little
insight into the radio communications consumer and military markets of the era to
fully appreciate the humor, but with most you can infer the meaning even if you
don't know the specifics. Some themes still apply today, like the influence of your
body adding capacitance to the tuning circuit of a radio to the extent that a station
comes in loud and clear while your fingers are on the dial or while you are near
the radio, then fades once you move away. It then becomes a challenge to detune
a bit to one side or the other, then move away and see if the station comes in clear.
If not, you detune in the other direction and see if that works. Sometimes, the
only solution is to situate yourself near the radio to get a good signal. 30 minutes
later, everything can change and you go through the ritual all over again. Integrated
circuit tuners have largely eliminated that problem, but there are still many around
affected by body capacitance.
