Radio Regulations (ITU) states (at least in my old copy) that "Administrations authorizing the use of frequencies below 9 kHz shall ensure that no harmful interference is caused thereby to the services to which the bands above 9kHz are allocated". In Norway, the Telecommunication law regulates all the electromagnetic spectrum (actually including signalling by a flash-light :-) , so at least over here it is regulated. --Magne / la1bfa
