Re: DRM decoder on FDM program

I think DRM only supports two simultaneous audio channels plus a simultaneous data channel. This recent article mentions this:

I don’t know if it is possible to decode all 4 channels simultaneously. I don’t think it is.

What might be possible is to open more than one Vrx and let them tune to the same DRM signal. It is in that situation probably possible to feed the audio from different channels to different virtual audio cables. I didn’t test this however.

Because i see that not all my questions are replied , it is better for me to as each of it separately
DRM mode transmission can support up to 4 channels
Can FDM listen to all these four separately or together ?
