How to know which data came from Mode S and which came from ADS-B (FIS-B)?
All the recorded transmissions you have, seem to come from the same aircraft. They come all from the onboard (Mode-S) transponder.

All transmission with Downlink Format (DF) 17 are ADS-B. Those with DF18 are TIS-B (or ADS-R), you don't have any of these (they are rare in Europe, and more common in the US)

Mode-S uses the following DF's:


DF4 - altitude reply (short)
DF5 - identiy reply (short)
DF11 - all call reply / Mode S squitter
DF20 - Comm. B / altitude reply (long)
DF21 - Comm. B / identity reply (long)
