SD Digital Transmitter

• Microprocessor-controlled amplitude modulated transmitter w/ continuously variable calibrated output power from 10 to 250 watts
• Operational frequency ranges continuously variable from 190 kHz to 1800 kHz.
• FET switching technology in the power amplifier, modulator, and the high and low voltage regulator modules resulting in an extremely efficient system
• Motorola ColdFire ® microprocessor designed specifically for efficient embedded systems Utilizes modern Direct Digital Synthesis (DDS) technology to create the audio and radio frequencies used by the RF Section
• Beacon operation is program controlled and monitored

SA Series High Power NDB

Designed to meet long range signal requirements for Low frequency applications, this high power NDB provides easy operating frequency adjustment as well as standard fully redundant dual backup transmitters and power supplies. Its ease of operation, sliding drawers and plug in boards have made the SA High Power NDB a trusted system throughout the world.

SA Series Low Power NDB

Designed to meet Low/Medium frequency applications in air conditioned shelters, high salinity offshore environments or hot desert regions, the SA series transmitter has served as the standard for Non Directional Beacons (NDB) for over 15 years. Its synthesized frequency adjustment, switch selected Identifier Code and built in test equipment have made it the most versatile and easiest to troubleshoot NDB on the market.
