Doesn't 73 mean "best regards" and SK just mean "end of contact"? I see that SK can also colloquially mean that an operator is deceased, though. Genuinely curious, not familiar with the hobby.

It's both. SK, Stop Keying, is used in CW (morse) whenever a station is done transmitting. SK is also Silent Key, but you'll rarely hear the abbreviation over voice or CW.

I don't know anybody who uses SK as end of contact. I've always heard it referred to as the operator being deceased.

It's a common prosign in CW at the end of a qso

Ah, okay, that might explain it. I was a voice in data-only person. I can't hear CW. Like, I suck at the patterns.
