I've been using a Geniatech HDSTAR dvb-s2 usb receiver (self powered) in my Raspberry Pi 4 running LibreELEC.
recognised by dmesg as SU3000HD DVB-S USB2.0 //: Montage Technology DS3000/TS2020
The reception has not been the best one on LibreELEC.
I've connected the same receiver to a Windows PC, and the signal and reception improved considerably !
My tests were with:
- raspberry pi4, libreelec: DVBLINK and TVHEADEND
- Windows 10: DVBLINK and SMARTDVB
using the same receiver.
A transpoder with 10% signal in LibreELEC on the Pi has like 55% signal in windows.
A transpoder with 30% signal in LibreELEC (pi4) has 80% signal in windows.
In the end, I can watch channels in windows with top quality, that are impossible to lock in linux.
As if windows driver has some way of enable some sort of "amplifier" in the driver.
Is there way of adjusting the "power" in the linux dvb driver ?
Or an update to the linux driver that is not included in LibreELEC dvb drivers ?
This problem happens with all LibreELEC module drivers (crazycat, and "latest" included with 9.2.3. Standard drivers do not support this receiver)
I've attached a link to my dmesg in LibreELEC.
I have also a running dvb-c receiver from silicon labs. Please ignore it.
Only consider the dvb-s2 receiver.
