[ARC5] Testing battleship radios

[Robert Eleazer]

One of my high school teachers, an early 1930's graduate of the Naval Academy, described testing radios intended for use on WWII Navy ships.

They tested the radio to ensure it was up to spec, then hung it from a long rope, pulled it back, and let it slam into a steel wall.  Then they took it down and tested it again.  It not only still had to work; if it had shifted frequency by more than 1 KC it failed.
