I agree with what PMB1010 said, re the LO freqs for a universal lnbf, HOWEVER, you really haven't said what LNBF you have, so that may not be correct. Ie what is important is that the settings in the receiver must match the lnbf that you have. Also, I sense you might have some confusion relative to "LO" vs "LOW". Ie people talk about say a 10750 "LO" freq, in which case LO refers to local oscillator freq, while some people refer to LO relative to LOW vs High LO freqs in a universal LNBF. Re "what is declination" , for your 30.6 latitude, you should use a declination of about 5.1 or 4.4 degrees, depending upon whether you use {the less accurate} south declination or the {more accurate, modified} extreme declination. Declination is the angle below the astronomical equatorial plane that the sats in the Clarke belt will appear to be, due to the fact that you are above the earth's equatorial plane, and the sats are not infinately far away. The bend in the axis of your
HH90 motor is 45 degrees, so what you normally do is subtract your declination from 45, then use this number for your dish elevation. In your case, 45-5.1 is 39.9 deg, corresponding to what you say you have your dish elevation set on. I'd really recommend using 40.6 however, except that this requires setting your motor latitude on about 31.2 instead of 30.6 .
ALSO, there is no SKEW when using a motor. It is always zero.
