FM 24-24 Chapter 6 Section VI. Single-Channel Tactical Satellite Communications Radios

AN/CSZ-1A--Sunburst II Processor

* This radio is an over-the-counter commercial purchase obtained by the US Army.

NSN: To be determined

Reference: To be determined

General Information

The AN/CSZ-1A Sunburst II processor provides high grade half-duplex secure voice and data communications over wideband and narrowband communications links. The Sunburst II supports both secure voice and secure data at 12 and 16 kb/s over wideband radio links. The unit also provides narrowband secure voice (LPC-10E) and secure data at 2.4 kb/s for radio or wire line transmission. The Sunburst II incorporates the indictor COMSEC module, and has been endorsed by the National Security Agency to encrypt voice and data up to the TOP SECRET level. Key features include ANDVT compatibility and the capability to receive OTAR in both narrowband and wideband modes. The Sunburst II provides the user with the capability to communicate to a host of existing COMSEC equipment such as KY-57/58 VINSON, ANDVT/KYV-5, KG-84 A/C, SINCGARS, Fascinator, STICS, and Sunburst I.
