[linux-dvb] 13/18V voltage with DVB-S 1.6 (Grundig 29504-491)

["Dr. Werner Fink" <werner@suse.de>]

Hi,

     this card in the subject does have sometimes problems
with horizontal transponder, especially with the that of
ZDF and KiKa.  It seems that the voltage may be to less
(< 18V).  If I use a so called inline amplifier the no
of the horizontal transponders are visible whereas the
vertical are really perfect and very fast switched.

Is there something like a phantom powering available to
help the DVB-S cards with their weak powering.  Or should
I use a multi-switch for this single LNB/LNC flat dish?

Maybe the register 0x20 could get an other value than
0x11 (first and fifth bit) within tda8083_set_voltage()
to get 18.5V instead of 18V ... if this is possible
with the Grundig tuner.

         Werner
