If you're an Avare/AvareX user with a Dynon HDX with their ADS-B module, please contact me. I'm interested in your Avare/AvareX experience and in helping to validate some code modifications I've made to AvareX to address various Dynon HDX issues.
This includes mitigation of GDL90 conformance problems and capabilities of the proprietary Dynon protocols for GPS, AHRS, and flight plan push/pull, etc. (which Dynon has graciously shared with me).
Blue Skies!
