U.S. Air Force high-frequency radio (11175 kHz) is active.
The ground station “Mainsail” is confirming the identity of two aircraft, callsigns “Rhetoric” and “Compress,” as they join a secure military communications network.
This frequency is used for strategic and nuclear command; activity may be routine, but it also may be tied to high-level operations.
