    Was listening to a group of hams on 75 meters the other night. Five or six in a round table. Every time they id'ed they gave their call sign followed by the word "thirty" What up with that? Sounds like a hold over from CB maybe.

    Maybe they just need a drink and can't pronounce thirsty.

    Maybe they're announcing their IQ. If you're looking for the Mensa Net, keep spinning. :D

    It's a secret code-word for their club. If you don't know the word, you can't talk. Good thing nobody can hear it.

    And Amateurs are still using it...sort of. In American (land line or railroad) Morse Code, the numeral 3 is Di-Di-Di-Dah-Dit; The numeral Zero is a very long DAH, approx. three times longer than a standard Dah. So, when you send SK (Di-Di-Di-Dah-Di-Dah) You are sending a close approximation of a Land-Line Morse 30.

    When you send ES for "and", you're sending a close approximation of the Land-Line Morse Ampersand (&).

    I hear some guys around here (OK, in a three state circle at least) on 75 that ID and say on the tens.

    I hear something similar on news radio when the traffic reports or weather reports come up on the X's

    If it's late at night, most of the folks on 75m are not thirsty. In fact, I'd guess most of them have had plenty to drink.
