Citizens Band Radio History
Invented by Al Gross in 1945, the CB radio originally served as a method of communication for troops
during World War II. After the war, Gross worked to make two-way radios a way of communication
for personal use and the CB radio service was established by law in the U.S. in 1949. It wasn’t until
the 1970s that technology advanced and the CB market caught on as a method of communication
between drivers to report police speed traps and road hazards.
The Citizens Band Radio Service consists of 40 channel frequencies that are mostly 10 kHz apart.
Transmitter power is limited to 4 watts in the US, and range can vary depending on the terrain and
quality of the product.
Currently, the Citizens Band service does not require a license for operation, regardless of age, as
long as the rules of operation established by the Federal Communication Commission (FCC) are
followed.
Petition For FCC Part 65 Rule Changes
In 2016, Cobra petitioned the FCC to revise Part 95 rules to allow CB radios to use frequency
modulation (FM). Cobra contended that FM offers improved speech quality and lower noise
interference, which improves the standard of two-way radios and is a benefit to the customer.
Through the direct efforts of Cobra Electronics and the enthusiastic support from loyal customers and
the distribution network the FCC granted the request. In 2021, Part 95 officially was updated to
include FM as an option for two-way radio use.
Today, thanks to Cobra Electronics’ petitions to improve the quality of the Citizens Band Radio
Service, users can enjoy the benefits of CB radio communication in a range of industries.
