10-4 Over and Out: Cops drop communication codes

TEN-CODES are code words used to represent common phrases in voice communication, particularly by law enforcement and and in Citizens' Band (CB) radio transmissions. The codes were developed in the 1930s to quickly and efficiently communicate across airwaves. 

Despite the long-standing tradition of ten-codes, police forces are dropping them. Problems occurred when departments joined forces during emergencies like 9-11 and the use of the codes created more inefficiencies than not.  Federal groups are now required to use plain language instead. 

Have no fear. We've still got it! Signing off...
10-4 good buddy!
List of most common ten codes:



10-0  Use Caution

PUNCH AND BEAUTY... What a great slogan for Ten4 DS!

"It has what it takes to improve communications by punching through loud and clear... And that's the beauty of it."
