I just want to make a quick announcement: gr-drm is now available for
Radio 3.7! Go and check it out under https://github.com/kit-cel/gr-drm!
also added a commit tag if you want to get the last version working with
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
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
project and a suitable HF front end (e.g. the USRP) you can set up your
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
DRM receiver, but also with the open source tool DREAM which can be
downloaded at SourceForge.
