You will need to provide details of your set-up and possibly a screenshot showing it. (Send PM if you like)Same issue as before, I only see network info, but calls are not going to TTT
A numeric value is expected here:Velocity:Horizontal speed is not known
This is fixed for next release.Velocity:10.0km/h
Space is a bit limited there.digiman1 said:Small feature request if at all possible.
When selecting a group to hold, currently it is listing the GSSI, Could we have the Alpha Tag from the TETRA_GSSI.txt file listing the groups?
I have a similar case with a specific Group that doesn't go throw TTT... All others are fine... I'm thinking it's due to the way the call is setup.TetraDecoder without TTT running, you hear voice?
See calls in TetraDecoder Network Window?
Your Tetra signal SNR ?
SDR# AudioFilter OFF?
Your quoting questions by 'hamradionl' saying that you have a similar problem. I don't understand.I have a similar case with a specific Group that doesn't go throw TTT... All others are fine... I'm thinking it's due to the way the call is setup.

I don't think this is a plug-in problem. (I could be wrong of course)Also the audio sometimes cuts out for like 200ms (you can hear it in the sample too), what could the problem be?
I see you specifically ask about this setting in SDR#. What is the correct setting? Should Filter Audio be OFF or ON?SDR# AudioFilter OFF?
That level should be OK.@thewraith2008 I work for one of the operators in the network and I have a Motorola Tetra Radio connected to that talkgroup, I can hear very clear without any cuts in my radio but it keeps cutting in SDR#, so I don't think it's a problem with the network.
Can it be low SNR 32dB?
Or maybe bad HackRF One Device?
I can listen to FM Stereo without any cuts, so it must be the demodulation that's failing somewhere.
Or maybe my laptop? I haven't tested it in any other computer yet
Latency less than 100mS will most likely increase the chopping. Mine is on 100mS (default?)Also when I change audio latency in SDR# it cuts less/more, I let it at 100ms.
I read online that it might be the usb port/cable/sdr device dropping samples, I will test it more and hopefully be able to fix it.
What about the Demodulator settings? What are your recommendations?tsapers,
Lowcost RTLSDR give much noise, static, and very poor PPM !
Tested with RTLSDR-V3 - AirspyMini, RSP1A, PLUTOsdr - good hardware seem very important/critical
AUDIO sample rate in file SDR.exe.config set to 48000
Audio Filter be OFF
freq Step 6.25
SNR 10 - 15 main NO or very poor decoding
SNR 15 - 20 some stutter + SDS faults
SNR 20 - 25 clear voice some minor dropouts + SDS
SNR 25++ very clear voice + SDS no faults
sample rate at 1.024 = low CPU % (older slow PC)
Waterfall OFF = low CPU % (older slow PC)
Bandplan OFF = Low CPU % (older slow PC)
FrequencyManager for fast switching between different network !
