The echoESX Mode S Transponder

The echoESX is the most affordable full range Mode S transponder with ADS-B for Light Sport and Experimental Aircraft.

  • 2020 Compliant ADS-B Out on 1090 MHz

  • Mode S transponder with 1090 ADS-B Out

  • Worldwide compliance

  • Meets TSO-C112e Class 1 Level 2els and TSO-C166b Class B1S

While other companies are looking to cash in on the ADS-B mandate by selling you a new transponder and WAAS GPS, uAvionix is taking a different approach. echoESX works with your existing avionics, allowing you to put your savings in the fuel tank and fly more.
