I didn’t realize it was fixed. What was the solution? They were complaining at Region 8 two years ago because I sent the first of our ADS-B equipped Pawnees to it. Darryl mentioned something about a FLARMnet database. How would I register our two ADS-B equipped tow planes on it?

The fix was a simple firmware update.
You can register ICAO addresses on FLARMNet.
Instructions are in the FAQs.
