What is the maximum permissible power for a local channel class C AM radio station?

The correct maximum permissible power for a local channel class C AM radio station is 1 kW. Class C stations are typically defined by their operational characteristics and are allowed to have a maximum power of up to 1 kW for their daytime operations. This limit is established to reduce potential interference with other stations and to maintain clear communication standards within the AM band.

In contrast, options like 10 kW, 100 W, and 5 kW exceed the specific power limitations that are designated for class C stations. While some AM stations may operate at those higher powers, they would fall under different classifications or necessitate specific licensing and operational restrictions to prevent interference and adhere to regulations set forth by the FCC.

Understanding the power limits is crucial for radio operators to ensure compliance with broadcasting regulations and proper functioning within the radio spectrum.
