VHF COM radios from Garmin, the GTR series. As the new-install replacement product for the popular SL40 model, the GTR series COM transceivers include a breadth of new features to reduce pilot workload.

These products have truly reinvented the stand-alone aviation COM radio with novel features like reverse database look-up and the COM monitor function, which bring new efficiency to cockpit radio management. Beyond that, these products demonstrate Garmin’s commitment to aviators worldwide, providing the solutions they need to meet the latest regulatory requirements in their regions, such as the recent SES mandate.

The GTR 225 includes 10 watts of transmit power and 25 kHz frequency spacing.

All products in the series have received the Federal Aviation Administration’s (FAA) Technical Standard Order (TSO) authorization.

For the European 8.33 spacing version, order the Garmin GTR 225A or 225B.

Worldwide Comm Database
Enter the airport identifier to find the frequency (or frequencies) associated with that location. Uses GPS input (from compatible systems, sold separately) to determine locations for each of the 25 nearest airports, Flight Service Stations, ATC facilities, WX stations, etc.

The series offers a variety of original features never seen before in a stand-alone COM radio. A unique frequency database makes it easy to find all the frequencies associated with a given airport or facility just by entering the location name or station ID. And when manually tuning a frequency, the reverse lookup function will automatically provide the navaid and/or airport identifier. Pilots can also find the nearest airport, area control center, flight service station, weather frequencies and VORs. All models also include a COM monitor function, which provides the utility of two receivers in one, allowing the pilot to listen to transmissions like ATIS without leaving the active ATC frequency, as one example.

The GTR and GNC series automatically store the 20 most recently called frequencies. Plus, the radios allow for storage of up to 15 favorite frequencies such as the pilot’s home airport or other frequently visited destinations. A familiar flip-flop feature allows channels to be entered in a standby window, and then activated with a press of a button. All models also include a built-in, voice activated two-place intercom making it a great solution for a two seat aircraft without an audio panel. A built-in timer can assist with approaches, holds and other assigned maneuvers.
