Thanks for this, Malich. There was just one part of the transcript of the interview that gave me pause:
Do you think DRM30 has proven itself via the decade-plus of HF/SW and AM/MW (and LW) testing?
Yes, time for testing is long over. The format works rather well. We released the Titus II at the HFCC conference in Miami FL a couple of months ago. With an engineering model, we went outside the hotel and received flawlessly a DRM30 test signal from the Vatican in Rome some 5000 miles away in the afternoon. It sounded like a local FM station. Most likely, that same signal would have been heard as well into Panama and the eastern parts of the US.
I wish proponents of DRM30 would not persist in trying to equate the sound quality of typical modest bitrate DRM transmissions to the sound quality from local FM stations. I can accept that the reception of a signal 5000 miles away may have been successfully error corrected for practical purposes [taking advantage of a robust transmission mode]. However I am confident the audio bitrate of the transmission from the Vatican would have been quite modest, in accordance with the usual practice for DRM broadcasts.
