CommentsThe factory no longer offers repairs for this radio.

We are sold out of the TRT-250, and do not expect to obtain more in the future. We have stopped selling this radio due to a lack of repair options for our customers. We will leave this page up as a service to the General Aviation community.

If you are looking for an alternative, we recommend the TRT-250D, with the gas-discharge display. The TRT-250D is still fully repairable.

The TRT-250D is not a slide in replacement, because the TRT-250D is approximately 1 inch deeper than the TRT-250. The mounting rack (which we can supply) would need to be changed. However, the back plate and wiring can be removed from the TRT-250 rack and attached to the TRT-250D rack, making it the easiest possible upgrade from the TRT-250.


Terra's TRT-250 transponder has an all solid-state design that eliminates the need for 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.

Please note that the factory no longer supports pushbutton Terra models. The initial price is lower than the gas-discharge TRT-250D, but it can be challenging to obtain service.

Other TRT-250 features include:
  • Mode C compatibility
  • Backlighted push-button switches
  • 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-250. When installed with an Encoder, the TRT-250 will report both your position and altitude to ATC (Mode C).
