If only there were a good library for using DRM (digital radio mondiale) with SDRs.

The "Dream DRM decoder" works fine for me.

The trouble is that most of the Broadcasters have abandoned DRM.

I just now did a quick scan. Of the 17 MW/SW channels I have programmed, there isn't one on air with DRM.

DRM broadcasts are definitely hard to find. A schedule is available here: https://www.drm.org/what-can-i-hear/broadcast-schedule-2/

I've used Dream before, and it works fine, but I wish there was a more modular option in the form of a library. That would be easier to plug into SDR tools.

I would write one when I get the time, but I've never been able to find the actual specification anywhere.

The documents look to be available here: https://www.drm.org/specification/
