To date two node are configured to decode DRM broadcast, Saint-jean HF, Canada, using only software trick and Rovigo, Italy using hardware downconverter. You can listen to DRM signal with nodes alternative audio stream.

DRM schedule can be found here.
http://www.drm.org/for-listeners/live-broadcast-schedule/


Here 3 screen taken from decoding software used to decode the DRM signal. Both node are using Dream 1.6.1cvs for windows, but the screen shot have been taken with dream 1.1.7cvs (by mistake)


first one is the main screen of the program where you can see audio codec, station name and song played.

Second one is the input psd screen where you can see the RAW signal input

The last one is the SNR history from past 15 minutes

Hi de9man.
I got Dream software for DRM with me, if you would like I could mail it to you.
I have never tried it though.

here dream 1.6.1 cvs (To my knowledge this is the latest compiled version for windows)

http://fmdx.gotdns.com/download/dream1_6_1.exe


Dream software is free and open source, but the compiled version is not compliant with GNU license so it's not technically possible for them to distribute it. this is why it's so hard to find it.

Edit, this is a auto-execute rar compressed file.

Two possible option to my limited knowledge. Receiving it using lsb 50khz 10khz over the native frequency (I use that trick with my icom until I buy a downconverter) and use virtual audio cable to decode the drm signal

Using a downconverter. Imply soldering a downconverter to the if stage of the radio (455khz). then plug the downconverter output to a soundcard line in.

I think you must use a hardware downconverter with rx-320d (between 30-50 euro investment) + a second sound card.
