Brandywine - Mystic Star

SELECT COMMITTEE ON ASSSASSINATIONS
Carl Amos Mather 3/20/78
Interview: Carl A. Mather & wife Mrs. Barbara Mather
Jack Morarity HSCA Interview Report:

“…Not that Carl isn’t used to being interviewed by government agents; he has a security clearance – and he has had since he started traveling with his company – he’s been with them for 21 years now. Has traveled overseas. His specific function deals with the installation of special electronics gear in aircraft. One such assignment caused him to be quartered in Brandywine, Maryland as he worked for some period of time at Andrews Air Force Base working on ‘Air Force Two’ – Vice President Johnson’s plane at the time.”

Mystic Star
The Mystic Star high-frequency single-side-band [SSB] communications system is installed at about 10-15 Air Force bases around the world, with remote transceivers controlled via telephone voice channels from Andrews AFB. This system is used for telephone traffic when Air Force One is out of range of other UHF links, but at least two SSB voice frequencies (and a full duplex 75 baud secure teletype channel called "India Oscar" which use a special anti-multipath modem) are maintained continuously and used for coordination of other communications links. Frequencies are chosen from a list of about 150 scattered throughout the available HF spectrum and are designated by "fox" code numbers which change from time to time.

Satellite communications are provided through Ultra High Frequency (UHF) Remote Switching Units (RSUs). The RSU is a UHF radio satellite ground entry point (GEP) station for the MSCMS. There are four RSU sites that provide the Mystic Star system with global UHF satellite coverage.

The four dedicated UHF stations: Brandywine, MD, San Vito, IT, Clark, RP, Wahiawa, HI. Each of these stations, except for Brandywine, has four dedicated radio levels; two wideband channels and two narrowband channels. The Brandywine station has six dedicated radio levels; four wideband channels and four narrowband channels for Mystic Star support. Satellite communications are under the control of the Master Control Center (MCC) at Offutt AFB, NE. The MCC has delegated its controlling authority to several Primary Control Centers (PCCs). Working within the Mystic Star system, and coordinated with the PCCs located at Brandywine, March AFB, CA; and Kadena AB, Japan. Brandywine is the PCC for the 23-degree west and Lincoln Experimental Satellite (LES). Brandywine 23W/100W…
