This is a map of approximate locations of radio transmitters suitable for RMT survey. Using this mat you can to estimate possibility of RMT survey on the particular place. If you have information about any radio transmitters not picked on this map, please send coordinates and frequencies of this transmitters to my e-mail shlykovarseny@gmail.com.  You can use any suitable format. The most useful is kml files (Google Earth). Please specify the frequencies of radio transmitters. I will add this information to the map. Together we can make the RMT method more useful!
