x From the British publication WIRELESS WORLD, February 1985: Pirate Navigation Interference Overcome "Helicopter pilots flying to the North Sea oil rigs have found it increasingly difficult to use their navi- gational aids to locate the rigs. This is caused by pirate radio stations operating at frequencies in the medium waveband used by standard non-directional beacons. Racal Avionics have [sic] solved the problem by designing (within a month) a new non-directional beacon with a much increased frequency range...." "...The transmitters are used as landing site locators or as route markers and the new design... allow[s] adjustable, reduced power outputs to be used from 100W stepping down to 20W. Because of the reduced power consumption, the beacon can be operated by solar, gas or wind generators at remote locations." -- =============================================================================== Bob Parnass, Bell Telephone Laboratories - ihnp4!ihu1h!parnass - (312)979-5414
