“ADS-B is a system in which electronic equipment onboard an aircraft automatically broadcasts the precise location of the aircraft via a digital data link. The data can be used by other aircraft and air traffic control to show the aircraft's position and altitude on display screens without the need for radar.”
A ‘search’ found the above - my system using Dynon Transponder always Shows ADSB NO RADAR & through a contact within the ‘system’ here, my setup performs & meets the required output.
