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


[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).

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

[http://www.dsp4swls.de/sodira/sodiraeng.html Sodira] free DRM30/DRM+ receiver. To receive DRM+ one option is to use a VHF to HF downconverver ([http://www.nti-online.de/eFMC%20108-28.htm FMC 108-20] 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.
