How many classes of AM stations are there?

There are four classes of AM stations, which categorize the differences primarily in their power and broadcasting range. These classes provide a framework for how AM stations operate and the services they offer.

The classifications are as follows:

1. Class A: High-power stations with a significant coverage area, operating predominantly during the day but often with nighttime operation too. They often have a large listener base.

2. Class B: These stations generally have substantial daytime power and limited nighttime operation.

3. Class C: They have even lower power levels and more restrictive operational guidelines, focusing on localized broadcasts.

4. Class D: These stations typically operate at the lowest power levels and may operate part-time with restrictions on their broadcasting times, often being non-commercial.

Understanding these classes helps radio operators navigate regulations, operational requirements, and the technical aspects of broadcasting. Knowing the distinctions also aids in frequency management to minimize interference among stations, especially as they operate on overlapping frequencies.
