Hi,
What I am doing wrong?
I use SDR Sharp & DSD+ & VB Cable
If I select WFM and select audio out in windows setting to speakers I can hear digital sound (buzzing and strange sounds) on NFM I can not hear anything (only see waterfall).
However when I set audio to VB cable DSD+ doesn't decode anything.
Screenshot is i att.

Re: Decoding DMR
Hi,
I managed it to work. I set input device in windows settings and now have sound.
My next problem is, laggy sound. works for sec or two and then breaks up. So I do not understand conversation.
I try to adjust gain and sampling mode to 1,8MSPS but result are the same.
Can you suggest what else can I do to successfully decode DMR?

Re: Decoding DMR
Try increasing the bandwidth slightly above 12,500, so that it covers a little more of the signal. ALso maybe your SNR isn't good enough, work on improving your antenna and tuning your RF gain settings.

Re: Decoding DMR
Hi thank you. I did improve modulation. It is not perfect, but defiantly better.

Ismit possible to run DMR demodulation on Raspberry pi B+?

Re: Decoding DMR
Yes, Raspberry Pi 3. It's a bit roundabout as you'll need to use something like Eltechs Exagear to run DSD+ on Linux ARM. See https://www.rtl-sdr.com/running-windows ... -and-more/.SloCharlie wrote: ↑Mon Aug 06, 2018 8:12 pmIsmit possible to run DMR demodulation on Raspberry pi B+?
Re: Decoding DMR
I see you have "filter audio" on.
deactive it.
you should turn other audio filter thinks also off.
Some people say you should turn "AGC" off but I leave it on.
You should also turn the un.... gain off!
