VFR flight tracking gdl 88 vs g 345 transponder


#1

Notice VFR flights are automatically posted to nearest departure and arrival airports with Garmin 345 transponder but not GDL 88 - instead must lookup by N number. Could it be different ADSB out frequency?
Any plans to have both post flight tracking

The gdl88 does UAT978

The 345 does 1090mh z

There aren’t man UAT receivers out there. I have one and it doesn’t have a great range. Maybe 30-40Nm.

Not related to VFR or IFR.
