If 10-9 means please repeat your message, what is 10-4?

Answer 1

Okay.

I understand.

Answer 2

There are 200 10-Codes in current usage, approximately 50 of these are used by the police, fire and other types of radio operators, while others have combined meanings depending on the service.
Any 10-Code signal can be made into a question by using it as a question.

Here are a few:
10-1 Receiving Poorly
10-2 Receiving Well
10-3 Stop Transmitting
10-4 OK, Message Received
10-5 Relay Message
10-6 Busy, Stand By
10-7 Out of Service, Leaving Air
10-8 In Service, Subject To Call
10-9 Repeat Message
10-10 Trnsmssn Cmpltd, Stndng By
10-11 Talking Too Rapidly

Hope this helps.
