Tracy OFACS, California. June 24, 2002
This OFACS (Overseas Foreign Aeronautical Communications Station) site was
believed to be built in 1959 and was an experimental CAA design to survive a
nuclear strike.  It's believed that this site was last used by the FAA as a VOLMET
(Routine Broadcast of Meteorological Information For Aircraft In Flight) transmitter
in the 1980's.
