Here are some of the ones you might hear...
'10' Codes, 'Q' Codes and Signal & Radio reports The "Ten" code - originally used by American Police. These are the most common 10- codes you will hear, usually said without the 10, i.e. "what's your twenty", "give me a nine", "anyone give me a thirteen" etc.
10-1 Poor Reception
