Centaur® Secure Public Safety Radio - HF Vehicular

The HF Vehicular version of the Centaur Secure Public Safety Radio or Centaur SPSR-HV1 provides high power Single Sideband (SSB) or Continuous Wave (CW) output, Automatic Link Establishment (ALE) versatility, and adaptability for long-distance communication application.

A rugged design, complemented with crisp, clean, secure speech, form the core of this highly-capable radio. An advanced AES-256 module provides high grade digital security. A data interface port and a GPS receiver data input are standard. A 1000 Watt amplifier is available as an option. Frequencies and operating modes may be programmed into any of the 200 memories available, or users may operate off the Variable Frequency Oscillator (VFO) directly. Programmable keys are provided for one-touch user operation.
