United States

The U.S. Department of State uses HF radio solely for emergency purposes, in a setup known as the Emergency & Evacuation Network (E&E). The network includes all U.S. embassies, consulates general, and consulates, as well as some domestic government offices and military bases.

The U.S. DoS has 10 dedicated frequencies, all on the upper sideband. Links are established using 2G ALE (MIL-STD-188-141A); the channels are scanned in descending order, from the highest to the lowest. Aside from those frequencies, the U.S. DoS stations may also appear on the USAF HFGCS network.

  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

The E&E is arranged into regional groups, comprised of a network control station (NCS) and a number of neighboring diplomatic missions. Each network performs plain voice radio checks regularly, usually once a week. A typical radio check may be heard on the following recording:
