To receive DRM+ one option is to use a VHF to HF downconverver ([http://www.nti-online.de/eFMC%20108-28.htm FMC 108-28] is a good option) together with a receiver like Pappradio (remember to turn off all band-pass filters). 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. We believe there is bug (bug confirmed by the author) in the DRM+ decoder of Sodira, that causes a drop of the SNR until a complete loss of sync after some seconds.

RX DRM

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

  • Dream The great free software DRM30 receiver and transmitter (see here to use Dream with USRP). Look for Pappradio for an affordable receiver hardware to use with Dream.
  • 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.
  • Diorama, Matlab implementation of a DRM receiver.
  • Wavesink Michael Feilen's DRM+ software receiver which uses the a RTL2832 dongle to receive a DRM+ signal. The only DRM+ receiver that really works.
