The use of "73" is used to mean "Best Regards". However I find myself saying "73s" (with an S). Just wondered about others.
A. I say "73". Sounds better to me. And is correct usage.
B. I say "73s" Sounds better to me. Didn't know its was incorrect usage.
C. I say "73". Sounds better and is correct usage.
D. I say "73s". Sounds better. Dont care about "correct usage".
