Hi all ...

The goal : IA6 @ 93W & IA5 @ 97W (KU Freqs)
The receiver : Coolsat 4000
The antenna : Channel Master E75 (36" x 26" Elliptical)
The LNB's : California Amplifier - Stacked Linear's , set for 4 degree spacing.

The question : On the Coolsat 4000, do I set the LNB Type as "OCS" for this setup ? If so, does the receiver automatically take care of transferring the horizontal transponders to vertical (25600-horizontal freq=vertical frequency) for you or does this still have to be done manually?

One other quick question ... what is the LOF of these LNB's .... 10750 ? (The markings on the LNB's are only that they are made by California Amplifier , there is a Star Choice logo and a part number 150462)

thanks

Input - 11.7 to 12.2 Ghz
L.O. of 10,750 for V and 11,325 for H
Output - 950 to 1450 (V) and 1525 to 2025 (H)
Max Noise Rating - 0.8dB
Power consumption - 200mA, 10.5 Volts to 24 Volts (nominal 13V recommended)

The StarChoice dish would of also come with a 22Khz switch for selecting the LNBF. Most common a 2 x 2 switch, but there were others as well. One input will be marked 22Khz ON

so you would set both LNB setups in receiver to standard setting...10750 LO frequency

One side will have the 22K on. The other would have 22K off :)

But that would only get you the Vertical channels from the two LNBF's. You still have to contend with the stacked issue. Would you not have to set your LO settings to LO1-10750, LO2-11325 to get the Horizontal as well? The 22Khz on/off would just select which of the two LNBFs to use. You could also use a subscriber unit to unstack the horizontal and turn it back into a voltage switched line, but then you need a power inserter and maybe a 22Khz injector as I do not know if the subscriber unit will allow the 22Khz signal to pass. The subscriber unit will not allow the voltage to pass and that is why you would need a power inserter with the subscriber unit.
