What are the meaning and importance of 73 and 32 in amateur radio language?

"73" and "32" are part of amateur radio lingo, also known as "ham code" or "numbers language". Here's a brief explanation of their meanings:

1. 73: Essentially, "73" is a Morse code shorthand symbol that means "best regards" or "my compliments". It's used as a friendly ending to a message. This usage dates back to at least the American Civil War. "73" has also been used in text-based communication to say "farewell" or "goodbye."
2. 32: The number "32" does not have a commonly recognized usage in amateur radio lingo. However, in the early days of telegraphy, it meant "I have a message for you" or "awaiting orders."

When amateur radio operators want to sign off a conversation, they often use "73". It helps to maintain goodwill among the group and signals the end of communication. On the other hand, the usage of "32" is relatively less prevalent in modern amateur radio language. As in general language, the significance is contextual, based on the circumstances and common practices among a specific group of people.
