This is a livestream of the US military's High Frequency Global Communications System (HGCS), which is used by the US military to communicate with various assets, including nuclear-capable aircraft and submarines, by sending Emergency Action Messages (EAMs) and Force Direction Messages (FDMs). These are encoded messages read in the NATO phonetic alphabet. Most messages are 30 characters long, but some can be over 200 characters long. A typical day might have about 10-30 messages anywhere, but I've heard anywhere from 0 to almost 80 messages. I've been monitoring the HFGCS on-and-off since January 2022.
