New C-band sat scan

  • usb dvbsky 960

    they know how to configure tvheadend to scan band C SAT it gives me an error

    linuxdvb: Technology M88DS3103 #1 : DVB-S #0 - failed to tune [e=Invalid argument]

    Only this universal option lnb. I do not see lnb band c

  • I found this method with a tp and it worked for me

    but I would like to scan normal as WITH UNIVERSAL LNB

    -----------------------------------------------

    Well i have been having similar issues on C band HD and SD channels on FTA

    as it seems TVheadend is not capable of scanning channels in the C band frequencies..

    i am using a TBS8920 card on it and in order to allow me to scan some channel tps not all of them i have to do the following maths..

    example:

    Channel name xxxyyyoooll

    C band HD frequency : 3790 V

    you have to calculate the following

    5150 C band frequency from the LNBF

    5150 - 3790 = 1360

    then add this value to the LNBF universal KU band frequency

    1360 + 9750 = 11110 frequency

    then just add new TP with this new frequency + normal c band symbol rate + polarization + PSK8 or different + pilot settings like you would do on normal C band frequency to scan the channel.

    This way i can tune most of the C band channels, aldo some i cannot might have to do with the LNBf C band type i am using.. cause i can get most on one Polarization only cannot get on both same time.
