Dream is a software implementation of a Digital Radio Mondiale (DRM) receiver. With Dream, DRM broadcasts can be received with a modified analog receiver (SW, MW, LW) and a PC with a sound card.
I like this software, but the problem is that it requires a special accessory or piece of equipment called a 455 kHz : 12 kHz down converter, which uses a raw AM IF 455 kHz output signal and the down converter down converts the MF frequency of 455 kHz and brings it down to a VLF frequency of 12 kHz for the Dream software to be able to decode the digital radio signal. Also it requires a special file for the activate the codec for to receive DRM. These down converters require a skill to build yourself or to get from some where who knows what they are. Most receivers have 455 kHz IF outputs, but no output with a 12 kHz IF out.
