CHARLESTON, S.C. – U.S. Navy communications experts needed HF radios for fixed-site, mobile, and shipboard applications. They found their solution from Rohde & Schwarz USA Inc. in Columbia, Md.

Officials of the Space and Naval Warfare Systems Center Atlantic in Charleston, S.C., announced a potential $16 million seven-year contract to Rohde & Schwarz on Friday for HF radio transceiver systems from the company's series 2000 and 4100 radio communications families.

The contract includes training, technical, and repair services for existing HF systems for the Navy and allied forces. Rohde & Schwarz will deliver two XK2900L HF transceivers and related equipment for $482,888, and the Navy will order the remaining radios through 2025.

The Rohde & Schwarz series 2000 HF transceivers consist of 1000-Watt single-channel narrowband radios with link capabilities and 200-microsecond quick tune capability. The company's series 4100 HF transceivers consist of 1000-, 500-, and 150-Watt single-channel narrowband software-defined radios with link capabilities and 200-microsecond quicktune capability. The series 4400. The Rohde & Schwarz series 4400 are VHF and UHF software-defined transceivers systems.

The Rohde & Schwarz series 2000 radio family is for shortwave telephone applications, data transmission as fast as 9.6 kilobits per second. These radios can enable users to set up high-power broadband communications systems on several channels with low-frequency separation and in different emission modes.

The core of the series 2000 family is the XK2100 150-Watt transceiver and GX2900 receiver-exciter for the 500- and 1000-Watt base station units. These units include six exchangeable modules and spare slots for options.

The Rohde & Schwarz XK2900L 1000-Watt HF transceiver comes as a desktop version or as a sturdy rackmount, and covers the frequency range 1.5 MHz to 30 MHz. It can be operated locally as well as remotely via an integrated, multistandard serial interface.

The series 2000 central control unit has a microprocessor that coordinates all internal control sequences for the modules via the SERBUS and communicates with external equipment via RS-232-C and RS-485 data interfaces, as well as via the keypad. The microprocessor also generates the messages and indications output on the graphic display.

The Rohde & Schwarz series 4100 500- and 1000-Watt HF transceivers are for stationary and shipborne communications that must cover large distances. These radios offer high radio link availability, even under moderate propagation conditions. These radios are for use aboard ships and on shore, and appropriate for civil air traffic control, embassy radio systems, and tactical applications.

The series 4100 HF radios support frequency hopping for security and provide interoperability with the The Rohde & Schwarz M3TR family of tactical radios in all HF operating modes. These radios can support future communications waveforms through software updates.
