I, too started with a wire recorder. About the same time.
I'd used it a little before I ever started into school, including
hanging a mic out the window, recording music off the radio. But, in
first grade my teachers were unhappy with my english, those were the
days of phonics being the be all and end all of teaching english. So, I
spent endless hours with the wire recorder practicing my phonics. Got
good enough to get a passing grade, which is all I cared about
In 1952 we moved to the Pacific NW. With most of our extended family in
Louisiana we all got tape recorders and corresponded by tape all through
the 50's and 60's. I also did some more "nature recording" using the
tape recorders. Limited by how far a extension cord went and that the
mic was the standard voice mic that came with the recorder.
I built my first parabolic mic in the late 50's. It was part of a air
sonar system I built for a science fair project. Everything in that I
designed from scratch with no help, power supplies, pulse oscillators,
amplifiers and so on, except the oscilloscope I used for the readout. I
could measure a distance to within less than a inch at 20'. It was very
noisy as the only speaker I had available was a hifi tweeter, so the
pulses were in the audible range. The parabolic was only 10", but big
enough to work, designed from a photographic light reflector. And the
whole thing won nothing in the science fair. That was the period when
anyone that wanted them could get relay banks that the phone company was
junking. And the phone company even had a handout on how to make a crude
computer with them. You guessed it, someone wired up one from the
handout and won the grand prize. All it could do is add two small
numbers. Last science fair I ever participated in.
