Current Shortwave High Frequencies
Shortwave service is provided by the Navy as an option for their ships
without the Navy's Direct-to-Sailor (DTS) capability. Shortwave also serves
as a backup to those customers with DTS. Shortwave service is also an
option for land-based listeners in remote locations that do not have access
to local or satellite-delivered AFRTS full Satellite Network (SATNET)
services. Shortwave services are intended to operate 24/7 but do experience
disruptions due to maintenance and atmospheric conditions.

Location Band Daytime Nighttime
Diego Garcia Upper Sideband 12,759 KHz 4,319 KHz
Guam Upper Sideband 13,362 KHz 5,765 KHz

KHz same as daytime
Pearl Harbor, Hawaii Upper Sideband 10,320 KHz 6,350 KHz

And note that 7812.5 is actually 7811.
