DRM test from North Korea on MW can be observerd via japanese SDR’s on the following frequencies: 657, 702, 765, 801, 819, 927, 882 and 999 kHz. The ID is “A00001” and the title is “조선중앙제2라지오방송”.
My theory: north korean government bought new transmitters from China with DRM capability, and the manufacturer added the “조선중앙제2라지오방송” station name. And the transmitters are in DRM mode initially, but north korean engineers cannot switch them to AM mode. Now they broadcasting useless DRM content accross the country, because “MSC” is missing.
