file that's needed to enable ADS-B?

Because of FAA's lame policies and dubious technical decisions
and indecisions, adoption of ADS-B in USA is extremely slow;
well behind other more advanced countries. You won't see much
ADS-B traffic unless you're near a large airport with frequent
international flights to countries more advanced in their ADS-B
implementation.

Sorry to say...
