Hi all, I just want to make a quick announcement: gr-drm is now available for GNU Radio 3.7! Go and check it out under https://github.com/kit-cel/gr-drm! I also added a commit tag if you want to get the last version working with GR 3.6. All others just get the latest version from the 'stable' branch. For those of you who did not hear of this project before: gr-drm is a fully standard conformant software implementation of a DRM (Digital Radio Mondiale) transmitter. DRM is a digital short-wave broadcasting standard aimed at replacing existing analog technologies in the long run. With this project and a suitable HF front end (e.g. the USRP) you can set up your own DRM broadcast. Out of the box, you can either transmit an audio file of your choice or even your own voice using the microphone input. However, please keep your local spectrum regulations in mind before going on air ;). Decoding of the created signal is possible with any commercially available DRM receiver, but also with the open source tool DREAM which can be downloaded at SourceForge. Greetings Felix Wunsch

Odd quirk I've noticed: JACK audio will not work, however WAV files will. Tried streaming in WAV files from FFMPEG, but the WAV source wouldn't read the shared pipe. Otherwise, ti works great. If you're curious as to what I am doing, you can see my terrible flowgraph here: http://sourceforge.net/projects/fmdigital/ Also, with WAV input, everything decodes great in Dream and SoDiRa. With JACK input (Audio source), the MSC does not decode.
