I will occasionally hear DPS 101 announce on DPS Base D, 155.4525, they are launching for a Patrol flight. I know they were based at Mesquite Metro Airport, but I noticed they were dropping into Mckinney National Airport quite often. Now I hear them announce a launch check adsb Exchange and they are launching from Mckinney, happened again today. Anyone know if they made a permanent move to Mckinney?
