United States

The United States Department of State uses HF radio solely for emergency purposes, as part of the Emergency and Evacuation Networks.[1][2] The HF-equipped stations include all U.S. embassies, consulates general, and consulates; selected DOS domestic offices; and selected U.S. military bases.

Frequencies

The DOS primarily uses the following 10 frequencies, all on the upper sideband. Links are established using 2G ALE (MIL-STD-188-141A) by scanning the channels in descending order, from the highest (24883.6) to the lowest (5748.6).

  1. 5748.6 kHz
  2. 6902.6 kHz
  3. 8058.6 kHz
  4. 10733.6 kHz
  5. 11168.6 kHz
  6. 13503.6 kHz
  7. 16283.6 kHz
  8. 18248.6 kHz
  9. 20810.6 kHz
  10. 24883.6 kHz

Aside from those frequencies, the DOS stations may also appear on the USAF HFGCS channels.

Operation

The U.S. diplomatic missions are divided into regional networks, comprising a network control station and a number of neighboring outposts.[3] Each network has a designated day of the week and time of day for radio checks, usually around 10 AM or 3 PM local time.

A typical DOS radio check may be heard on the following recording:
