NOTE: PDF data sheet above has a comprehensive listing of all this radios's specs.

• One programming kit can be used for all RRD radios; very cost effective and it 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.
