root@et8000:~# cat /proc/bus/nim_sockets
NIM Socket 0:
        Type: DVB-T2
        Name: Si216x
        Has_Outputs: yes
        Frontend_Device: 0
        I2C_Device: 3


The greatest  SNR Si216x(DVB-T2) of 55%.
At the same time USB DVB-T AVerMedia(A835) SNR 99%.

If SNR Si216x(DVB-T2) = 52%, AVerMedia(A835) SNR =  96%.

What could be the problem?

I have the same tuner-mode T2, models 8000 and 10000, works fine, but the signal plays continuously from 0 to 90%, apparently a problem with the driver!In a C-mode no problems!

Thank you.

 

Receiver freezes when you turn from the deep standby.
The system is busy, there is no video, only audio.

You do not have these problems?

Sorry, you are right, issue for the SNR Readout/Calculation not fixed at all for DVB-T, maybe for DVB-C.

I don't have an et8000, but others seem to have little problems with them. What is exactly your configuration and what is the exact problem?

This is a very big problem.
The receiver does not work after wakeup from deep standby mode.
