United States

The U.S. Department of State's HF activity consists entirely of radio checks, with no diplomatic traffic passed. All U.S. embassies and consulates are obliged to have HF, VHF, and/or UHF radio systems as part of the Emergency & Evacuation Network, and these systems must be tested at least once every month.[1] It encompasses not only fixed stations, but also hand-held radios and units installed in vehicles.[2]

The following ten numbered channels are used for radio checks worldwide, all in USB mode:

  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 callsigns associated with U.S. diplomatic missions take form of either K__## or WNG###. These callsigns may be suffixed to indicate the type of radio unit in use:

  • No suffix: Fixed unit
  • "MO": Mobile unit
  • "OS": Off-site unit
  • Single letter: Unknown

The activity consists of linking using 2G ALE (MIL-STD-188-141 Appendix A) followed by plain voice exchange of link quality information. The hundreds of U.S. diplomatic missions around the world are divided into regional networks, where a single mission is designated as the hub with which radio checks are made. Sometimes radio checks are also made between networks.

Example radio check between KWX57 (the U.S. embassy in Warsaw) and KWS95 (the U.S. embassy in Tirana)
