TBS 6981, Archlinux 5.8.13 and frequency limitation #216

Closed rajil closed 3 years ago

rajil commented 3 years ago

I am using the driver shipped with 5.8.13 and tried to do a blind scan with w_scan2.

The log below throws up a warning "unsupported by driver: min=0.95, max=2.15". Do i need the Closed source drivers to scan this frequency range?

Driver accept intermediate frequency 950-2150 Mhz, you try scan C-band satellite with Ku universal LNB params - so wrong IF passed to driver. Set rigth LNB params for C band and try again :)

Thanks for the tip. Is this the right way to do it?

Unfortunately, it doesnt detect any channels.

ERROR: Sorry - i couldn't get any working frequency/transponder
 Nothing to scan!!
rajil commented 3 years ago

The LNB is of type Inverto Unicable II. Is there anything special which needs to be passed by the scanning utility?

rajil commented 3 years ago

I changed the LNB to a simple dual port LNB.

I am able to scan with TBSviewer in Windows but both w_scan2/dvbv5-scan are failing.

In Windows, 762 channels on found image

P.S. Look like you have outdated transponder list for 83E. All Ku band transponders DVB-S2,8PSK with SR 32720 Ks https://www.flysat.com/gsat10-30.php

Is it possible to export Lyngsat to a format as in /usr/share/dvb/dvb-s/Insat-4A-83.0E ?

rajil commented 3 years ago

I compared my /usr/share/dvb/dvb-s/Insat-4A-83.0E with https://www.lyngsat.com/Insat-4A-and-G-Sat-10.html, and they mostly match. This is the file i used to scan with dvbv5-scan above.

Any idea why dvbv5-scan is not getting any channels? I will need to check the transponder list for w_scan2.

By the way these are the contents of /usr/share/dvb/dvb-s/Insat-4A-83.0E which have PSK/8

I was able to scan with w_scan2 after modifying the satellites.dat file as mentioned here.

Once w_scan2 was able to lock the tuner, dvbv5-scan also started working.
