What is the frequency range classified as Medium Frequency?

The correct classification for Medium Frequency (MF) is indeed within the range of 300 kHz to 3,000 kHz. This frequency range is significant in maritime communication because it allows for reliable communication over distances that can extend to hundreds of kilometers, especially during nighttime when the ionosphere reflects these frequencies effectively.

Medium Frequency is utilized for various forms of radio communication, including maritime distress signaling and other maritime operational communications. Understanding this frequency range is crucial for operators using GMDSS systems, as it plays a vital role in ensuring safety at sea and reliable communication among vessels and shore stations.

In contrast, the other options represent different frequency ranges: the range of 10-30 MHz corresponds to High Frequency (HF), 1,000-10,000 kHz actually encompasses all of HF and part of the MF range, and the range of 30-300 kHz is classified as Low Frequency (LF). Familiarity with these classifications helps maritime operators determine the best communication frequencies for various situations.
