[linux-dvb] Re: Can't tune to the Hi-Band

Perhaps you're talking about the SatCom array. I believe that was
designed for circularly-polarized DBS here in North America where
there are no skew-set issues. I suppose you'll pick up
linear transponders. But hang on, I must be totally off-base, you're
talking about 22kHz tones which make sense only in Europe. This
must be a linear high/low band antenna, right? European antenna
people help please.

If you are able to get it working with the Windoze sw, then szap
should also work out of the box.

   Exactly how are you making these high and low LOF settings? I
   would expect that you should compile an unmodified szap, edit
   your .szap/channels.conf file, and run szap <Channel>. szap
   will set your tone and the LNB will react accordingly.

Maybe, that's it. Got it from eBay - but it's not THAT uncommon...

Sorry, I'm not that well equiped...

Well, if I set the high LOF to 9750000 I can receive all channels between 
11,7GHz and 12GHz. Set to 10600000 I can only receive the low-band.

The strange thing is, using the Hauppauge software with Windows, it works 
perfectly with the preset values (9,75GHz, 10,6GHz, 11,7GHz). 

Thanks a lot,
