These cables will will carry a signal to penetrate the earth and detect if gas/oil is below. There will also be some small explosive charges at times in the earth and these will be detected also by the cable and fed to a master station. Does anyone know what frequency is transmitted down these cables or mode of transmission PULSE etc This could be a source of QRM for the LF/MF radio amateur and most people do not know it is taking place and wondering where the QRM is coming from. There will be a network of cables for hundreds of miles lying on fields and ditches etc while the exploration is going on de mal/g3kev
