I remember seeing an only World War II vintage teletype machine. It would print test from an HF receiver. Given the technology of the day it had no software inside
The way it would work is you spin a disk at a nominal one rev per second and disk has electrical contacts on it that make a bit stream. Phase lock that with WWVB. So you control the motor speed. Actually I think you'd be better off using the 60KHz carrier. Again limiting yourself to only 1940's technology, I think you could build a local oscillator that would phase lock to WWVB's carrier, and from there you control the motor speed and and then you use the spinning disk to decom the bits. -- Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
