What are the primary classes of FM stations in the United States?

The primary classes of FM stations in the United States include Class A, Class B, and Class C.

Class A FM stations are typically designed for local coverage, with relatively low power and typical operating ranges up to 25 miles. They are crucial for providing radio service to smaller communities and specific regions.

Class B FM stations have a wider broadcast range and can reach larger populations. They can operate at higher power levels than Class A stations and often serve suburban and urban areas.

Class C FM stations represent the highest power category, often serving large metropolitan areas. They can have very significant coverage areas, offering a greater reach and more robust signal strength than the other classes.

This categorization is important as it defines how the stations operate within the spectrum, their coverage capabilities, and the specific regulations applicable to each class. Understanding these classes empowers operators, engineers, and enthusiasts to comprehend the FM broadcasting landscape within the U.S.
