Say goodbye, fading
Volker Fischer at the Technical University of Darmstadt in Germany is writing an open source decoder for Digital Radio Mondiale, the digital shortwave format that’s in testing right now (which shares the unfortunate acronym DRM with digital rights management....) The Frauenhofer Institute announced last week that they would be selling a software-based receiver for $60 that requires a modified analog receiver with an IF output at 12 kHz rather than the usual 455 kHz. But this open source software, aside from being free (free beer!), promises to decode the broadcasts not via the IF, but from the audio channel. That would be a lot cheaper than sending my AOR 7030 to England to be modified to output 12 kHz, particularly if the software is ported to Mac OS X, which wouldn’t require building a cheap PC.... (Thanks Rik van Riel for pointing me to this.)
