Hello nunigaia,
Yes, i understand that all this is a hobby, i posted after installing the debug script, i didn't want to give you an incomplete answer. That's why it took 3 days.
And after a week without any feedback, i thought that it interests nobody.
Back to the problem:
Yes, i am trying on uno4kse, the turbo tuner connected was deactivated for running my tests. I even uninstalled it in order to only have the t230 geniatech connected.
Same tuning problem with the geniatech tuner on a zero4k.
Another old hauppage dvb-t tuner works on that zero4k, but showing snr = 0.
The problems appeared with openbh version 5.0, they did not exist with 4.4.
Best regards
Spearkie
