echoESX ADS-B Out Mode S transponder (Experimental)

An AV-30-E or AV-20-E panel display is required to configure and control the echoESX EXP.

echoESX from uAvionix is a state-of-the-art remote mount Mode S ADS-B Out transponder integrated with a high-performance GPS receiver. Designed for both experimental and certified aircraft, echoESX provides seamless cockpit integration, simplified installation, and reliable ADS-B compliance, significantly enhancing situational awareness and operational efficiency.

Designed to integrate seamlessly with AV-30-E and AV-20-E displays, echoESX also features an internal GPS receiver—eliminating the need for a separate GPS installation. For certified aircraft, an optional TSO-certified GPS antenna from uAvionix completes the package.

Designed for quick retrofit installation that clears up your panel compared to traditional ADS-B Mode S transponders, echoESX is an easy replacement for your existing Mode C transponder with the ability to use your existing installed monopole transponder antenna.

The echoESX combines a space-saving remote-mount design with ultra-efficient operation. Its minimal Size, Weight, and Power (SWaP) profile makes it an ideal upgrade from bulky legacy transponders, reducing strain on your aircraft’s electrical system.
