• Direct replacement, plug and play units.

• One programming kit can be used for all RRD radios; cost effective and also simplifies    the maintenance and upgrade process.

• Dedicated In-Service-Adjustment (ISA) port minimizes the risk of programming wipes    and radio damage. Competitors utilize a programming pin in the HTD harness    exposing the radio to the risk of dangerous voltage levels during programming.

• Software programmable for 12.5kHz narrow or 25kHz wide band.

• Both low & high power are programmable; factory delivered at 2 and 8 Watts    respectively. • 450-470 MHz frequency range.

• Frequency stability standard @ 1.5 ppm for fixed applications.

• Ultra fast TX/RX attack times.

• Controlled Envelope.

• Meets FCC and IC Canada standards.

• All electronic settings are software programmable.

• No on-board or hardware adjustments are required.

• SMD component design.

• Designed and manufactured in the USA.
