[Sundtek]

Does that single Tuner work?

/opt/bin/mediaclient --enabledreambox=/dev/dvb/adapterX/frontend0

I think the "Auto-registering" mode only recognises one tuner automatically, we'll change that shouldn't be hard to add support for multiple tuners there - thanks for spotting this.

[Dima73]

Single tuner work fine.

Now both work(visually, further tests needed).

[Dima73]

Tested(sorry, a lot of work at the end of the year).
Second tuner - work fine same as first tuner.

/usr/sundtek/sun_dvb.sh add

case "$1" in
     start_c)
....
if [ -e /etc/sundtek.conf ] && [ "`grep -c dreambox_support_fe1 /etc/sundtek.conf`" != "0" ]; then
           echo `date +"%Y-%m-%d %H:%M:%S [$$]"`" Using /etc/sundtek.conf for deviceconfiguration" >> /var/log/mediasrv.log
+           $DRIVERPATH/mediaclient --enabledreambox=/dev/dvb/adapter3/frontend0

I checked the new version, the same problems.
The second tuner is not recognized.
Need manual fix

[Sundtek]

As far as I know that's just a workaround we will update the driver source for it soon.

[Dima73]

Ok.Wait.

[Dima73]

Hi Sundtek
Install new drivers

The second tuner is not auto recognized.

[Dima73]

There is a problem.
SNR value always 91%.
Is it possible to make dynamic values, at least a little closer to reality? 

[Sundtek]

The unit is not % it's in dB

By my experience if you have 91 it's pretty good.
There is no real range given in the Linux DVB API (and the value is returned by the chipset),
I'd prefer to keep it that way since various clients are using it that way for years already (the receiver part is the same as with the current single tuners which are available since 2018).

Also the values cannot be returned in a more accurate way than what the hardware returns (they might be transformed, but might loose accuracy by doing so).
So the application should better do that transformation.

[Dima73]

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

[Dima73]

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 This is an old API version that has now been superseded."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
1) https://github.com/OpenPLi/enigma2/blob/5af9063bdb4254368315f8969378b95b720aeaa3/lib/dvb/frontend.cpp#L1350
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.
