Interesting discussion came up at club meeting about proper vs informal Q-code usage. While not an egregious use of this Q-signal, it is technically incorrect when people say "QTH IS Springfield" - QRM is often used (incorrectly) as a noun.

Sometimes Q-codes are used informally with a slightly different meaning. In informal ham language, some codes have slightly diverted from their original meaning and are used just as a replacement for a specific word.

What's the consensus on this? Should we stick to the ITU International Radio Regulations from 1947 definitions, or has modern usage evolved? Curious what others think about maintaining traditional meanings vs accepting common usage.

Great question! QTH stands for "My location is _____," and when followed by a question mark, the Q-signal turns into a question. So technically "QTH Springfield" is correct, not "QTH IS Springfield." That said, everyone understands what you mean. I lean toward proper usage in formal nets but don't stress it in casual QSOs.

As someone who operates a lot of DX and contest stations, efficiency trumps rigid correctness on the air. It helped cut down on the amount of code that needed to be sent, and later it found it's way into voice communications especially for DXers or contesters who may have a limited time to work a particular station. These codes help us communicate and to pass information as quickly and effectively as possible.

The QN signals (q-codes) are special ARRL signals for use in amateur cw nets only. They are not for use in casual amateur conversation. Do not use QN signals on phone nets. Say it with words. There's definitely a place for proper usage, especially in formal traffic nets where precision matters for message handling.
