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

*[http://sourceforge.net/apps/mediawiki/drm/index.php?title=Main_Page Dream] The great free software DRM30 receiver and transmitter (see [http://www.olifantasia.com/projects/gnuradio/mdvh/examples/dream/ here] to use Dream with USRP). Look for [http://www.pappradio.de Pappradio] for an affordable receiver hardware to use with Dream.

*[https://github.com/fewu/gnuradio_drm 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.

*[http://www.drm-sender.de/ 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.


*[http://www.dsp4swls.de/sodira/sodiraeng.html Sodira] free (but not free software) DRM30/DRM+ receiver. Native support for the RTL2832 is comming soon in order to properly allow DRM+ reception.

*[http://nt.eit.uni-kl.de/static/diorama/index.html Diorama], Matlab implementation of a DRM receiver.

*[http://www.drm-sender.de/ Wavesink] Michael Feilen's DRM+ software receiver which uses the a RTL2832 dongle to receive a DRM+ signal. The current version only supports CELT audio (no AAC support yet).
