Genesys Digital Radio (GDR)

The Genesys Digital Radio (GDR®) is a family of remote-mount, software-definable radios. They feature combined VOR/localizer/glideslope and marker beacon navigation and VHF communication with a frequency range of 118-136 MHz or 118-156 MHz and 25 or 8.33 kHz channelization with transmit power of 16 or 25 watts. Embedded UHF 225-400 MHz communication is available as an option. The radio is designed to interface to a host controller/display that has the capability to control the navigation and communications functions via RS-232, or ARINC-429 serial interfaces.

Features of the radio include:

  • Utilizes 28VDC aircraft power and complies with MIL-STD-704E
  • Automatic selection of VOR or LOC mode of operation by channel frequency
  • Automatic pairing of LOC (Localizer) and GS (Glide Slope)
  • Reception and decoding of the VOR or LOC signals
  • Reception and decoding of the GS signals
  • Reception and decoding of the marker beacon signals
  • OBS input via bus for operation of analog CDI in VOR operation
  • Drives analog instrument panel CDI & VDI and/or autopilot
  • LOC enabled annunciator output for autopilot gain control
  • Internal Glide Slope and ILS/VOR RF diplexer
  • Selection of COM and VOR/ILS channels via RS-232, ARINC 429, or RS-422 bus
  • Two PTT Inputs for VHF or UHF transmit selection
  • Dual VHF and UHF full-time reception
  • Support for two microphone inputs, two audio outputs, and separate sidetone output
  • The COM subsystem functions as either:
    • Class D Receiver with a Class 3 Transmitter (25 KHz channel spacing)
    • Class E Receiver with a Class 5 Transmitter (8.333 KHz channel spacing).
  • The VHF COM transceiver operates in the RF frequency range of 118.000 to 155.975 MHz
  • The UHF COM operates in the RF frequency range of 225 to 400 MHz
  • Separate guard selectable for 121.5 or 243 MHz operation
  • DME tuning via ARINC 429 output
