73 — What It Means in Ham Radio

73 — Best wishes, have a good one.

The standard sign-off, left over from telegraph shorthand. Say "seventy-three," singular — you will hear people say "seventy-threes" and it is technically wrong, though nobody will correct you.

How you would hear it

"Seventy-three, and thanks for the contact."
