Try this as has been also said in this thread turn off the deemphasis

Does anyone know if it's possible to decode TETRA with a RSPduo ?
Thanks !

So, it looks like it's not possible

From my research so far, there seems to be a plugin available for SDR#.

https://www.rtl-sdr.com/sdr-tetra-plugi ... res-msys2/
https://www.hamdigitaal.nl/2018/01/tetr ... -voor-sdr/

This will work with an RTLSDR dongle, but unfortunately, it seems that the SDR# software does not support RSP radios.
The other option I found was Telive which is for Linux which works in conjunction with GNUradio:

It seems that Telive can also be run on Windows:

The links above describe the setup with an RTLSDR, but GNUradio uses SOAPSDR which can link up with an RSP:

The setup looks rather complex and although I had hopes of being able to set this up sometime, but so far I have only compiled Telive. At this point, I don't know whether its viable yet.

Hi StandingWave,

Thanks for reply and the several links.
I was aware of the TETRA plugin for SDR# but I'm looking for something I could use with the RSPduo. I don't know Telive but it indeed seems a bit tricky to set up ! At last for me.

Considering there are hundreds of TETRA signals in the 400-500 MHz range,I hope someone will soon provide a simple decoder for the RSP. It's a bit frustrating not to be able to decode them with such a powerful soft/SDR.

Regards
