HF airband

From HFUnderground

HF aeronautical bands. The 3800-3950 kHz range is generally not used in ITU Region 2 and is shared with other services. 3 kHz frequency steps (channelization), USB voice used with SELCAL extensively used. Military generally uses 3 kHz steps but will sometimes use split or offset frequencies and non-voice modes.

See the MWARA page for specific frequencies, including VOLMET broadcasts (meteo) transmissions, weather frequencies and HF long-range ATC frequencies. Additional resources include:

• New York Radio
• Aircraft SELCALL (Selective Calling system used over HF radio voice circuits)
• VOR
• ILS
• DME
• Non directional beacon or NDB

This page is for the bands only.
