SDR# RTLSDR v4 + SDRSHARP revision 1919 + Tetra module no voice

[Ivalpe]

hello everyone. Has anyone from the community tried the RTLSDR v.4 + SDRSHARP revision 1919 + Tetra module configuration? There is only roger beep sound. I have installed the rtlsdr.dll file indicated by the manufacturer but there is no solution. Thanks for your help.


Video test

Your video shows that you have bad signal reception (~55-85% with flickering 'Received').
You get some decoding but not enough to decode call control and voice reliably.

The gain level (42.1 dB) and use of RTL AGC is probably introducing distortion.
Use should be using WFM and bandwidth of 25000. (set-up is covered in documentation)
The 'roger beep' heard is a feature of TTT, read the documentation to see how to stop that.

don't enable RTL AGC inside Source, better adjust RF Gain manually.

Esa version no funciona bien y con el RTLSDR v.4 menos todavia. Te aconsejo usar la 1716. WFM y si estas cerca de la estacion base, no uses RTL AGC.
