I punched in a bunch of west coast AR freqs. Most of the ones they use out of Travis are AR8B/A, AR7A/B. I hear a lot of T38's with the callsign ROPER out of BEALE. After the build of the 21/3 Assault runway I hear a lot of C17 flights out of McChord AFB and March AFB as well, some times in formation flights.
