SkyTV VIII dual - enigma2

Dima73:
It not  dynamic values.
If this were the case, then I wrote the recalculation code in the enigma itself.

Dima73:

--- Zitat von: Dima73 am März 03, 2021, 09:55:46 Vormittag ---There are two options in enigma2.
"Force legacy signal stats"-->"If set to 'yes' signal values (SNR, etc) will be calculated from API V3. This is an old API version that has now been superseded."  yes/no

2)Manual recalculation https://github.com/OpenPLi/enigma2/blob/5af9063bdb4254368315f8969378b95b720aeaa3/lib/dvb/frontend.cpp#L940

Sundtek:
it is a dynamic value, there's no hardcoded value in it. For good systems I usually see 89-91, but there are also worse 70.
You could probably crosscheck by adjusting the attenuation. The outcome can just alter the value given by the chipsets, it won't change anything else.

"Sundtek DVB-S/S2 (IV)" seems to do some recalculation.

Dima73:
Ok, I'll check everything again.

Dima73:
I checked that dynamic values work very badly.
 I used was the VU+DVB-S dual tuner, so the calculation of the values is very accurate.
1)
VU+DVB-S dual tuner -->SNR 94%
Sundtek-->SNR 91%
2)
VU+DVB-S dual tuner -->SNR 64%
Sundtek-->SNR 90%
The value was very low and the picture on the HD channel began to freeze.
