Marco! Polo!

CW (continuous wave / Morse code) over RF in the 1900s.

Walkie talkies and car phones in the 1940s.

AMPS cell phones in the 1980s.

Mostly though they’re right. When you used telecommunications systems you were largely communicating with a location or a known station, not a personal identity. Fascinating to think about.

The CW folks would presumably be sending QTH instead

I wonder if this graph captures that/if it would make an appreciable difference?
