The 200-300 MHz freqs are no longer current. The entire band was 'rebanded' a few years ago and the upper 300MHz section is now used exclusively by digital trunked radio systems. VHF-lo could still be accurate but is usually only heard within 20 miles of an operational base/range or when the Ionosphere is really hoppin'. VHF-hi is hit or miss - many units are in the transition phase of going over to 300MHz or 400MHz trunked systems.
I do know the 146th AW at Point Mugu in Ventura uses 305.6 for Ops and 319.3 for Tac... Many ANG bases use 267.5 as a 'Base Ops' channel. Check the communications section of your local airport/base on AIRNAV for frequencies.
