[vdr] Re: LNB freezes...

Maybe? Water are Dipols and we know from our microwave oven
that water inacts with microwaves...or big snow crystals?
(How urban tales starts ;-))
But, serious, there once were LNBs where a motor turns a little wire
horizontal or vertical...if that is frozen?
But: If this would not work, you'll have no receiption at all
on the other polarization or see the wrong channels.

LnbSLOF = 11700 The switching frequency (in MHz) between low and high LOF
LnbFrequLo = 9750 The LNB's low and high local oscillator frequencies (in MHz)
LnbFrequHi = 10600 (these have no meaning for DVB-C receivers)
