What is HF and Shortwave?

[Brunlea]

Here's a brief overview of HF (High Frequency) and shortwave radio:

HF (High Frequency)

• Frequency Range: 3 to 30 MHz.
• Uses: Long-distance communication, amateur radio, international broadcasting, and maritime communication.
• Propagation: HF signals can travel long distances by reflecting off the ionosphere, a phenomenon known as skywave propagation.

Shortwave

• Frequency Range: Generally considered to be part of the HF band, typically from 3 to 30 MHz.
• Uses: International broadcasting, amateur radio, and emergency communication.
• Propagation: Similar to HF, shortwave signals can travel long distances by bouncing off the ionosphere.

For more detailed information on specific frequencies and schedules, you can check out resources like the Shortwave Radio Schedule Database or the Radio Society of Great Britain.
