G3X and G3X Touch System Users,
Garmin previously communicated that a ground station software issue prevented the ground stations from reliably providing TIS-B services for aircraft equipped with 1090ES ADS-B Out and dual frequency (978/1090 Mhz) ADS-B receivers like the GDL 39/39R, and provided a temporary configuration work-around.
The FAA has communicated that this ground station issue has been corrected, so it is no longer necessary to set the ADS-B 1090ES IN field to NOT SUPPORTED on the GTX 23ES transponder configuration page.
G3X and G3X Touch systems may now set both the ADS-B UAT IN and ADS-B 1090ES IN fields to SUPPORTED to correctly indicate that the GDL 39/39R is a dual frequency receiver able to directly receive the signals from both types of ADS-B Out aircraft with no help from the ground stations.
This transponder configuration change also applies to those using GTX330ES transponders, but in this case, the configuration change is made on the transponder itself.
We completed a test flight yesterday with this transponder configuration change and observed excellent operation, so we have no reason to believe that this issue has not been resolved as reported.
Please let us know if you have questions.
Thanks,
Steve
