Gain More than Just a Comm

Designed specifically for light sport (LSA) and experimental aircraft, the GTR 200 combines powerful Comm capabilities with advanced workload-reducing features formerly only found in high-end certified systems. Its slim 1.35” tall design allows you to make the most of limited space in your panel while 10 W of transmit power helps ensure solid communications between you and ATC or other aircraft in your vicinity. Information displays on the large, sunlight-readable display with brightness levels that can adjust automatically to the natural light level in the cockpit, or can be adjusted manually by the pilot. The GTR 200 offers 25 kHz channel spacing and utilizes a standard density 37-pin connector for easy installation.

Going above and beyond the call of duty of a traditional Comm, the GTR 200 includes a 2-place stereo intercom that is ideal for 2-seat aircraft; no additional hardware is required to communicate with your passenger. Advanced auto squelch automatically senses the noise level in the cockpit and adjusts the mic squelch for effortless intercom use regardless of the cockpit noise level. Listen to music inputs with Hi-Fi, home theater-like quality, featuring bass boost as well as pop, classical and rock music equalizer options. Pilot-configurable soft keys can provide 1-touch access to emergency frequency tuning, pilot audio isolation, saved frequencies list, music mute or push-to-talk. Plus, optional installed remote switches on the flight controls allow pilots to keep their hands on the controls while performing functions like swapping the active and standby frequencies.

Reduce Your Workload

Know exactly to whom you’re talking with the GTR 200. The device will display the facility name and type when you are tuning from one of the 20 user defined frequency preselects, or selecting a frequency from one of the nearest or flight plan airports (when transferred from a compatible Garmin aviation portable or G3X™ system). In addition, the GTR 200 automatically stores the 20 most recently accessed frequencies for easy retrieval. The 121.5 emergency frequency is also never more than a button press away; simply hold down the frequency swap button to tune it.

Enjoy Crystal-Clear Standby Frequency Monitoring

With its standby frequency monitoring feature, the GTR 200 gives you the ability to listen to ATIS while monitoring ATC. Swapping your active and standby frequencies is done with a single touch of a button or optionally installed switches on the controls. Even in single-radio aircraft, you’ll no longer have to worry about missing an ATC call or other critical transmission. 3D Audio capability separates the active and standby frequencies in your headset so it’s easier to differentiate between sources.
