SouthofI-10,
Just to clarify for all those who read this thread:
For a universal LNBF, the correct setup is either "UNIVERSAL" or 9.750/10.600 GHz. Both or either must have the 22 KHz tone set to ON or AUTO.
When the 22 KHz tone is ON it activates the high band Local Oscillator (10.600 GHz). When the tone is OFF, the low band Local Oscillator (9.750 GHz) is active.
If you select the LNB setting as UNIVERSAL (or select the dual L.O. selection of 9.750/10.600) and set the 22 KHz tone ON, it will, or should, automatically turn the 22 KHz tone ON or OFF based upon the transponder frequency that is dialed in. This way you do not have to fuss with the settings of the 22 KHz tone for each transponder, consider ON as AUTOMATIC. ON is more akin to ENABLE in this case as the tone will be switched ON or OFF as needed without your intervention. The transponder frequency that is dialed in will control the tone.
If you set the L.O. to the single setting of 10.600 GHz, then you must have the 22 KHz tone set to ON in order to activate that local oscillator. The 22 KHz tone will then be ON all the time. The low band L.O. will never be enabled in this case. Since you are aiming at the region of the satellite arc that does not have any low band Ku signals you do not need the low side of the LNBF which is the 9.750 GHz L.O. (Local Oscillator).
It is Okay to select the single L.O. frequency of 10.600 GHz with the 22 KHz tone set to ON. That selects and enables the 10.600 GHz L.O. to access the high Ku band signals (only), which is acceptable for what you want in this particular scenario. In this range of the arc, there are no low band Ku signals, so you do not need the 9.750 GHz L.O. and it shall work just fine.
I posted this information just for a quick review. More info to come on 123.0°W.
