Guten Tag Uwe,
What does the signal level and CNR look like?
Not sure if your TV viewer app can display those stats.
The femon plugin in VDR can do it.
There are command-line tools that can show these stats:
https://linuxtv.org/wiki/index.php/Dvbv5-zap
https://linuxtv.org/wiki/index.php/Dvb-fe-tool
I am slightly sad that these tools show signal level in %, rather
than dBmW or dBuV.
In my experience with a single dongle (the T230C2), CNR of 25 dB is
barely okay. I've never seen a CNR better than say 38 dB.
Frank
