Product Description

EVX-R70 digital two-way repeater features

Better Flexible Support: Analogue, Digital and Mixed Modes
The EVX-R70 conventional repeater operates in both analogue and digital modes and can be used with any existing analogue two-way radios. Includes “mixed mode” to dynamically switch between analogue and digital for flexible support.

Better Compatibility and Efficiency
eVerge™ radios are compatible with over 74% of the digital radios deployed worldwide using TDMA protocol. eVerge™ digital radios operate with the TDMA (Time Division Multiple Access) protocol for spectrum and power efficiency providing lower total equipment cost compared to FDMA. TDMA digital radio systems support twice as many talk groups and calls without more licensing costs.

Continuous Performance 
Get 100% continuous duty at 45 Watt VHF and 40 Watt UHF for easy integration into most repeater sites. Includes integrated power supply with connector for optional external DC battery backup.

Multicolored LED Status Indicator
LED indicator enables easy monitoring of repeater status. Status indicators include: power, digital/analogue mode, repeater disabled, transmit analogue/digital mode by slot, and receive analogue/digital mode by slot.

Additional Radio Repeater Features

  • EIA Rack mount size
  • AMBE+2™ Digital vocoder
  • 26-Pin accessory connector
