r Force versions operate in other bands using amplitude modulation (AM) waveforms. The SINCGARS family of radios has the capability to transmit and receive voice and tactical data, and record traffic on any of 2320 channels (25 kHz) between 30 and 88 MHz. A SINCGARS with an Internet controller is software capable [2]. PLRS (Position Location Reporting System) A command-and-control aide that provides real-time, accurate, three- dimensional (3D) positioning, location, and reporting information for tactical commanders. The jam-resistant ultra high-frequency (UHF) radio transceiver network automatically exchanges canned messages that are used to geolocate unit positions to 15-m accuracy. Commanders use PLRS for situational awareness. PLRS employs a computer-controlled, crypto-secured master station and an alternate master station to ensure system survivability and continuity of operations. The network, under master station management, automatically uses user units as relays to achieve over-the-horizon (OTH) transmission and to overcome close-in terrain obstructions to line-of-sight (LOS) communications. When a rugged portable computer (PC) is used with the user unit, it becomes a mini-command-and-control station with a local area map superimposed with position and identification (ID) information. The computer interface and network control make PLRS a software capable radio system [3]. AN/WSC-3 A Demand Assigned Multiple Access (DAMA) satellite communication (SATCOM) terminal. It meets tight size and weight integration requirements. This single-waveform radio has a computer (Ethernet) interface and is software capable [4]. AN/ARC-164 HaveQuick II A LOS UHF-AM radio used for air-to-air, air-to-ground, and ground-to-air communications. ARC-164 radios are deployed on all US Army rotary wing aircraft and provide anti-jam, secure communications links for joint task force missions in the tactical air operations band. This radio operates as a single- channel (25 kHz) or a frequency-hopping radio in the 225-399.975 MHz band.
