A big change for a different part of the radio dial...
Federal Emergency Management Agency has mandated the implementation of "NIMS" - the National Emergency Management System - by October 1 2005. This means, that police and other emergency services are required to cease using the "ten codes" on CB radio transmissions in favor of speaking plain english.
The purpose is to make sure messages are understood in emergency situations like earthquakes, hurricanes, tornadoes and of course the rare terrorist attack. All recipients of federal preparedness funds must adopt and use NIMS. In short, while truckers may continue to say "10-4 good buddy" The police may not. 10-7 friends.
10-1 = Receiving poorly
10-2 = Receiving well
10-3 = Stop transmitting
10-4 = Message received
a fairly complete list here:http://home.att.net/~wizardoz/cbmw/10codes.html
10-CODES ARE OKAY AFTER ALL
Homeland Security Secretary Michael Chertoff has changed his mind and won't require the abolition of 10-codes in everyday law enforcement communications as a condition of compliance with N.I.M.S. and eligibility for future federal grants. His announcement was received at the Annual Conference of the International Association of Chiefs of Police with warm round of applause.
