Finally I could decode the sound. Needs good SNR and still occasionally drops out...

I have long said that DRM is junk! Even on the Kiwi receivers it has a hard time to decode.
Here are the DREAM optimum settings which I have found work best in my case:
Channel Estimation: both settings set to Linear
Audio Section: nothing selected
I usually monitor the Spectrum -> Shifted PSD to make sure that there is a nice square waveform in the bandbass.
I have been decoding DRM since early 2020 and have had limited success as well. Some stations you will not be able to decode the audio using DREAM v2.1 because of the CODEC being used. If I recall, DREAM v2.2 will decode HE AAC v2 but only works on Windows 10.
Here are some regular/familiar DRM stations on the dial:
Voice of Nigeria, Abuja
WINB
KWT Radio Kuwait Digital
TDF Radio France
RRI Galbeni
Tip
Go to the EiBi shortwave schedules page http://www.eibispace.de/ (http://www.eibispace.de/) and download eibi.txt. You can do a search (Ctrl-F) for the keyword digital. Alternatively, get the CSV database and then filter it in Excel.
Happy listening.
