My tracking of nearby ADSB-out aircraft using my local AWACS server.
Being within the KIAH Mode-C ring, all planes are required to have a squawkable transponder for the primary ATC radar.
Unfortunately, most of these planes are invisible without the 1090MHz transponder which allows for a MLAT(multi-lateration)
calculation with multiple base stations. Sometimes an ADSB-IN aircraft is flying nearby which will activate
a ADSB-R (rebroadcast). The traffic within several miles and within 5000' of the aircraft will be rebroadcast meaning
that my AWACS system can now see the ground traffic at major airports as well as random signatures for the remainder of
the transponder only flights.

Since it's more expensive to add ADSB-in capability and not required by the FAA many planes don't have this.
Fortunately, using almost the same setup as my home AWACS system Stratux
can supplement your electronic flight bag. I'm currently using Avare
with the external i/o plugin to connect to the
homebuilt stratux.
