Which frequency range is designated for AM radio broadcasts?

The frequency range designated for AM radio broadcasts falls within the Medium Frequency (MF) band, which typically spans from 530 kHz to 1700 kHz. This range is specifically allocated for amplitude modulation (AM) radio services.

AM radio operates effectively within this frequency range due to its ability to propagate over long distances, especially at night when atmospheric conditions favor the transmission of MF signals. As such, MF is the standard designation for AM radio broadcasts, enabling clear reception and wide coverage for listeners.

In contrast, the High Frequency (HF) range is primarily used for shortwave radio communications, which can include international broadcasting, but is not suited for standard AM broadcasts. Very Low Frequency (VLF) is used for navigation and time signals rather than general broadcasting, while Super Low Frequency (SLF) is utilized for specialized applications like submarine communication and is not applicable to AM radio broadcasting.
