Since 1945 I have been receiving a DRM signal on 9810. Although S/N ratio was initially good, around 18dB, there was no station ID shown on the Dram decoder software, but 2 data channels were shown, both of type MM with a bitrate of 8.64kb/s. As this is a frequency used at other times of the day by Radio Romania, I suspect that it is them. Is MM a multimedia mode? I've tried a web search but can't find anything definitely called MM. The signal is still present @ 2035, but is now much weaker.
