    Xverters The first beacon started operating on 432.075 Mhz. in April 1979. In 1980 the 1296 Mhz. beacon was activated. In 1981 the 144.170 Mhz. beacon started sending it's signals to the Mainland West Coast of the United States. There is also a 10 Ghz. beacon which is turned on when conditions are favorable.
