Were "Q Codes" in use by Marconi Operators in 1912 ?
There was a discussion about the use of "DDD" and "QRT" previously.
As I interpret it, "DDD", as Phillips sent it, meant "To Californian ! YOU stop sending immediately ! I am working Cape Race !" Evans received the "DDD" and there was no need for an acknodgement. He simply shut down.
Was "DDD" a code just used by Marconi Operators ?
In Amateur Radio "QRT" usually means "I am going to shut down my station". This usually means he is shutting down his whole station - He will not be transmitting or receiving.
"QRT?" (QRT with a question mark) Is a question from one station to another "Shall I shut down my station ?" and would require a reply as to "Yes" or "No". ?
Question was if such use of "QRT" would have been in use in 1912 ?
These "Q Codes" are used on voice transmissions (I guess a bit informally) on Amateur Radio. You will hear this, for example:
"Well, it's getting late and I am going QRT for the night."
Or
"My QTH (location) is ...........°
