All-in-One COM Radio and Audio Solution for Modern Aircraft
Upgrade your panel with the slim, cost-effective GTR 205 COMM radio — combining powerful VHF communication, advanced audio processing and built-in intercom functionality in one compact unit. Ideal for experimental, light sport and general aviation aircraft.
Designed for Compact Panels
With a slim 1.35-inch height, the GTR 205 fits easily into smaller instrument panels without sacrificing capability.
A large, bright, full-color LCD display ensures excellent readability of frequencies and system information in all lighting conditions.

Worldwide Frequency Database
Enter an airport identifier, and the GTR 205 automatically retrieves relevant frequencies — including tower, ground, ATIS, clearance delivery and more — from its worldwide database. Send the selected frequency directly to standby for quick access.
When paired with a compatible GPS source, Frequency ID displays the name and type of the tuned frequency, so you always know who you’re communicating with.
Standby Frequency Monitoring
Monitor a standby frequency (such as ATIS) while remaining on your active channel — improving situational awareness without interrupting communications.
Built-In Intercom
The integrated two-place intercom comes standard and delivers clear cockpit communication between pilot and co-pilot.
Optional enablement expands the system to a four-place intercom with:
Advanced Audio Capabilities
Auto Squelch Technology
Automatically adjusts mic sensitivity based on cockpit noise levels.
3D Audio Processing
When used with a stereo headset, audio sources are spatially separated for improved clarity and reduced workload.
COMM Playback
Record and replay up to 150 seconds of previous transmissions — ideal for reviewing clearances or missed calls.
EQ Settings
Selectable bass boost and equalizer profiles (rock, classical, pop) enhance music listening quality.
Bluetooth® Connectivity
Pair your smartphone or compatible device to:
-
Stream music directly to your headset
-
View song and artist information on the display
-
Control playback (play, pause, skip, repeat)
-
Receive and manage incoming calls
-
View signal strength and battery status
All directly from the radio interface.
Expandable Audio Panel Features
Dual-COMM Switching
Connect a second COMM radio via AUX input. Switch between radios or monitor both simultaneously. In the event of power loss, backup mode automatically connects the pilot’s headset to the second radio.
