What is the frequency range for the MF designation?

The MF designation refers to the Medium Frequency band in the radio frequency spectrum. This frequency range is specifically defined as falling between 300 kHz and 3 MHz. The common usage of the term often relates to AM broadcast radio, which typically operates within this range.

Choosing the correct range helps in identifying the various transmission capabilities and applications associated with different frequency bands. Medium Frequency is notably used for AM radio broadcasts and maritime communications, making a solid understanding of this range essential for tasks involving communication systems and radio operations.

While other frequency ranges provided in the options correspond to different classifications in radio frequencies—such as VHF (30-300 MHz) and UHF (300 MHz and above)—they do not apply to the Medium Frequency range that encompasses 300 kHz to 3 MHz. Thus, confirming that the specified range in the correct answer accurately reflects the standard definition for MF.
