Other option for DRM+ reception is the USRP, using GRC - [http://www.oz9aec.net/index.php/gnu-radio/grc-examples examples here] - to grab the I/Q channels and output it to a [http://software.muzychenko.net/eng/vac.html VAC], then to [http://www.drm-sender.de/?page=tools#1 RateMonkey], and then to Sodira.

RX DRM

There are some good options in order to receive and transmit DRM30 and DRM+ currently available.

  • qt-drmplus QT-based SDR DRM+ receiver with librtlsdr as frontend.
  • Dream The great free software DRM30 receiver and transmitter.
  • GNURadio DRM blocks All the power of GNURadio and DRM together! This recent Felix Wunsch work implements a DRM transmitter in this stage, and in a next stage will also implement a DRM receiver. Comes with gnuradio-companion examples supporting both file and USRP outputs.
  • Spark free (but not free software) DRM30/DRM+ (also FM/RDS and AM/AMSS) transmitter that supports direct RF output (possible hardware options include the USRP and Diragen). Also supports the use of the royalties-free codec CELT.


  • Sodira free (but not free software) DRM30/DRM+ receiver. Native support for the RTL2832 is comming soon in order to properly allow DRM+ reception.
  • Diorama, Matlab implementation of a DRM receiver.
  • Wavesink Michael Feilen's DRM+, DAB and FM software receiver which uses the a RTL2832 dongle to receive the signal.
