Uses switching technology in power amplifiers and regulator modulator modules
Input power to RF output efficiencies are greater than 80%
Crystal-controlled synthesizer
Dual-tone generator
DIP switch-programmable
Morse Code keyer
Automatic shutdown circuitry
VSWR protection
Optional voice processing circuit
transmitters are supplied IP66-Certified aluminum enclosures for permanent installation in extreme environmental conditions
Dual systems consist of two fully redundant transmitters and auto-transfer unit
SA transmitters are also available for installation in customer supplied standard 19” racks.
Note: The auto-transfer is an integral part of a dual radio beacon system, providing the switching mechanism to allow either transmitter to act as primary. If one unit shuts down, the other is activated automatically.
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.
