Equipment of controlled source radiomagnetotelluric method (CSRMT) operates in frequency band 1-1000 kHz and experience of its application for the solution of engineering tasks in Chukotka region (far North-East of Russia) are described. The CSRMT method allows us to work in remote areas where there are not enough radio transmitters. A new RMT-C system includes transmitter and receiver groups with a grounded electric dipole as a controlled source. Using of 3-4 main controlled source frequencies from the range 1-150 kHz and their several odd harmonics allows us to realize CSRMT soundings in frequency band 1-1000 kHz. Application of such technique does not require the emitting of a big number of frequencies and a measurement at one station takes little time. Results of investigations by the RMT-C system in Chukotka region has been confirmed by drilling.
