HFGCS LIVESTREAM 251222A

This is a livestream of the High Frequency Global Communications System (HFGCS) using a rotation of KiwiSDRs. The HFGCS is used by the US military to broadcast Emergency Action Messages (EAMs) and other communications. From FY 2026 documents, the Department of Defense summarizes the HFGCS as follows;

"The High Frequency Global Communications System (HFGCS) program provides the Department of Defense (DoD) with a critical unique strategic asset: a global, high-power, high-frequency (HF) network. This network ensures resilient communication for both nuclear and non-nuclear command and control (NC3/C2), serving a wide range of users, including US Strategic Command (USSTRATCOM), Air Mobility Command, the White House Communications Agency, Navy submariner forces, and other government agencies like the Department of Homeland Security and the Federal Emergency Management Agency (FEMA).

"HFGCS is essential for disseminating critical information to global strategic forces, especially in contested environments where satellite communications might be compromised. The program leverages a network of 13 strategically located ground stations and two network control stations equipped with modern, commercially based, HF radio technology, ensuring beyond-line-of-sight communication with aircraft, ships, and land-based platforms."
