SETTING UP SKYVIEW DIGITAL SATELLITE CARD

Universal Ku band LNBs have internal capability to switch polarisations and to switch local oscillator frequencies. For example Vertical or Horizontal polarisation by altering the DC supply volts 13 volts or 19 volts and to switch the LO frequency from 9.75 to 10.6 GHz using a 22kHz tone OFF/ON.

C band LNBs are normally single polarisation, with the direction defined by the half dipole pin inside the rectangular waveguide and with single local oscillator frequency.  

If your C band LNB is simple like this, then put the same LNB LO frequency into both LO frequencies on the screen and turn the 22kHz tone off.  It then does not matter what voltage you select, 13v or 19v.

Check the 5700 MHz figure on the label.  It is more likely one of these: 5150, 5750 or 5950MHz.  The 5150 is used worldwide, the higher ones for some Indian satellites, I think.

If you have some unusual complex C band LNB with options, you need to read the LNB data sheet.  What are the manufacturer and model number and what exactly does it say on the label.
