Show HN: A new protocol for packet radio including ECDSA and compression

AFAIK it dates back to the 1930’s when spy networks were HF Morse code. Clandestine ops used HF morse well into the 1970’s, perhaps later.

Pretending to be a ham was a form of cover.

Sadly, being a cracker-jack Morse code operstor doesn’t get you a job with the NSA any more :) Technology has moved on.

Well, not the NSA, no—but the same skills that help with Morse are still helpful for radio listening.

The prohibition on scrambled meaning long pre-dates WW2, and goes back to old analogies about fencing a commons.
