Harris Announces New Digital HF-SSB Radio System

Harris Corporation's Long Range Radio Division has developed a new, extremely compact HF radio system designed with advanced, digital signal processing techniques. The RF- 5000 was introduced at the 42nd AFCEA international exhibition held recently in Washington. Also introduced was Harris's full line of state-of-the-art military communications equipment.

In a unit weighing only 15 pounds, the RF-5000 Series digital radio system provides built-in high-speed data modem, adaptive HF (ALE) frequency management, ECCM (frequency hopping), digitized voice and burst transmission capabilities, at a greatly reduced cost. Near-term product improvement plans include embedded voice encryption.

The tactical 20, 125, or 400-watt vehicular or fixed-station system features a common receiver-transmitter with optional plug-in communications system upgrade modules.

The receiver-transmitter is just 7 inches wide, 5.5 inches high, and 12.1 inches deep.

The RF-5000 Series radios can provide adaptive HF (ALE), ECCM, and high-speed modem waveforms in MIL-STD 188 standards.

The programmable digital modem allows co-resident, new high-performance waveforms along with existing waveforms (such as FSK). This simplifies conversion to new equipment while maintaining interoperability with existing assets, a key concern in military planning today.

A complete line of 20, 125, and 400-watt power amplifiers and fasttuning antenna couplers are available for applications in tactical vehicular and fixed-station communications networks.

Standard features include 1.6 to 30-MHz frequency coverage in 10 Hz steps; 99 preset channels; channel scanning; over-the-air or keypad programming; built-in test to the module level; and ruggedized, submersible construction.

A detachable front panel allows remote control up to 50 meters away. Multiple transmission waveforms and Forward Error Correc- tion (FEC) support 2400 baud operation for optimal performance in single-frequency or frequency-hopping mode. A Linear Predictive Code (LPC) module digitizes voice signals for transmission in an advanced ECCM environment.

Harris Corporation, Rochester, N.Y., is a $2.1-billion supplier of information, communication and semiconductor systems, products and services to government and commercial markets worldwide.
