Saying "over" on the radio is like the null byte at the end of a string.

    Reminds me of that old TV trope of saying “over and out”. This is not how you end a radio transmission. “Over” means that you are finished talking and are now awaiting a reply, “out” means that you finished talking and going to stop listening for a reply. Saying both together is contradictory, you only say “out” when you’re done.

      Ah, so “out” is like an EOF!

      Same with roger wilco. Roger means i understand the message. Wilco means i understand the message and will comply.

      When I learned this in JROTC, it has ruined me and I get so upset when I hear it in media now. Been like 30+ years and I’m still angry when I hear it.

    Or like saying “And uhhh… Yeah.” at the end of a voice memo.

    “Come on over!”

    “Come on WHAT? Over.”

    130Saying “over” is the old radio protocol. The new radio protocol is starting by saying the number of the characters in the message.

    So is “uhhhhhhhh” on a pilot announcement STX?

      That’s the keepalive message for when there’s a delay in the data query to prevent the passengers from closing their connections.

    Did you know that HTML has something similar.

    Reminds me of some TV show where a rookie cop tended to forget that and the cop on the other end just stubbornly waited for an answer, every time.

    Of course you can always just stop listening after n bytes, no need for a null byte then.

      You always add a timeout. It’s a basic safety.
