Reed gave us a demonstration of an “aperiodic receiver” that he constructed.
These were essentially untuned radio receivers with lots of audio amplification but not much signal sensitivity.
They were used during World War 2 to locate possible enemy transmitters. Only a very few were made.
Morse code from a milliwat transmitter could be plainly heard in the receiver.
