Two other variables to consider. First, where do you fly because there is sparse ADSB coverage in certain parts of the country? Secondly, at what altitude do you fly? Somewhere I believe I read that the ADSB towers have a "three tier" configuration based upon altitude coverage.
Suggest you go fly above 10,000 feet in some location where there is radar coverage, nearby........and report back as to the results.
My $.02 worth.
