DRM is part of the MF and HF bands today, albeit with a most uncertain future. Actually I bought a DRM license from Winradio back in 2007, to test with the SDR-IQ and later the Perseus. My trials were disappointing - I needed almost 20 dB SNR to decode, and another 5 dB to get stable reception. Not to mention the sound card problems. With the Excalibur I got decoding at around 15 dB SNR, and stable reception at around 18-19 dB. DRM with the Excalibur is very much plug and play, if you chose to install the DRM player when you installed the software and driver.
