About DRM 
DRM, short for Digital Radio Mondiale, is the worlds only non-proprietary, digital system for AM with the ability to use existing frequencies and bandwidth across the globe. 
With near-FM quality sound offering a dramatic improvement over analogue AM, DRM will revitalize the AM broadcasting bands below 30 MHz in markets worldwide. 
Broadcast Partners is at the forefront of this...

Add extra channels 
The DRM receiver is capable of receiving four DRM stations. To add a channel, simply add a crystal. The crystals (X1, X2, X3 and X4) are used in the first down conversion from the station frequency to the 10.7 MHz IF frequency. Therefore, the frequency of the crystal should be 10.7 MHz higher than the desired frequency.  Specification of the crystals used:
