While FM mode is new to CB users in the U.S., it isn’t new to radio. AM/FM capable CB radios have been legal in Europe and several countries in other parts of the world for years, where FM is now the main mode of communication due to its superior sound quality. Adding FM mode to CB radio in the U.S. was approved by the FCC thanks to the efforts of Cobra Electronics and our customers. 


Cobra asked our customer base for feedback on their interest in using FM mode. We gathered input from many sources – including online CB radio forums, off-road vehicle clubs, distributors, and more – and the result was a resounding yes! With wide acceptance for allowing FM frequencies on CB radios by our customers, the FCC finally approved the change in September of 2021.
