Commonly used at the end of conversations between hams, roughly
equivalent to "best regards." Or more informally like "Aloha" or
"Caio." Abbreviations like that grew out of the desire to shorten
commonly sent words and phrases when using Morse or International
Code.

Serious question. What does "73" mean?

I have a stack of "73"mags. I'm not a ham however.
If I was, I of course would know.

Anybody? I know it's a stupid question, but I don't know.

TIA,

Dennis
