Hi all

Trying to make ExpertSDR2 work with DSD+, i experienced some issues with the NFM mode .

To be short, I succeeded in making the chain ColibriNano + HDSDR(extIO) + DSD+ work:
- VHF
- NFM mode (12.5 kHz bandwidth large)
- output to VB-CABLE input interface

Everything ran fine in this configuration. But, when i use ExpertSDR2 instead of HDSDR, DSD still received the filtered+demodulated signal (can see in the signal scope) but does not decode anymore the voice channel (DMR)

I tried in WFM mode, and in NFM with a larger filter (say 20 kHz or so) but no success.

I guess this might come from a filter applied to NFM mode.

Does anyone has already tried this configuration ?

thanks in advance

Hi, Marek.
Thanks for informing us of that issue. At the moment we can't check that, but in the middle of developement of ESDR2 1.3 we'll look into it.
