LF/MF
Seemingly some cables are being layed through out some
parts of the UK for GAS es OIL exploration. 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
