Comments: This transponder is almost a slide-in replacement for the Terra TRT-250. It uses a different rack (about one inch deeper), but the backing plate and wiring can be transferred to the TRT-250D rack.
Comments: The only wiring difference with the TRT-250 is the dimmer, which is not needed with the TRT-250D's self-dimming display.
Comments: When available, the newer "Terra by Trimble" units are available at extra cost.
Comments: Due to the unusual shape and point in its life cycle, most TRT-250D sales are direct replacements of the same radio. If this is a new installation, and you need the Rack & Connector, they are available at extra cost.

Product Description

Terra's TRT-250D transponder takes the all solid-state design of the TRT-250, and adds a more readable display and a number of convenience features. Like the TRT-250, the TRT-250D does not use a cavity tube. As a result, reliability is improved, and no warm-up time is needed before operation. This unit is small, lightweight, and has low power drain.

Other TRT-250D features include:

  • Planar gas discharge display
  • Simultaneous display of active and standby codes
  • Pushbutton code flip-flop
  • Single knob code selection
  • Pushbutton VFR code selection (1200)
  • Mode C compatibility
  • 200 watts nominal power output
  • 4096 discrete codes
  • System test capability
  • TSO'd

You may also be interested in an Encoder to use with this TRT-250D. When installed with an Encoder, the TRT-250D will report both your position and altitude to ATC (Mode C).
