Citizen Band Frequency Reference

In September of 1958 the Class D CB service was created on the 11-meter band at 27 Megacycles, and this band became what is popularly known today as CB (Citizen Band) Radio. Originally there were 23 CB channels until the 40-channel band plan was implemented in 1977. Channel 9 was designated for emergency use and channel 19 became widely adopted for truck drivers and highway traffic communication.
