HF Communications

HF (High Frequency) communications refer to radio transmissions in the 3 to 30 MHz range, used for long-distance communication. These signals can travel beyond the horizon by bouncing off the Earth's ionosphere, enabling voice, data, and Morse code exchanges over thousands of miles without satellites or cellular networks. HF radios are commonly used by military, aviation, maritime, and amateur radio operators for reliable long-range communication, especially in remote or emergency situations where other methods might fail. The technology relies on the ionosphere's reflective properties, making it a versatile and proven means for global communication.
