your local oscillator frequency needs to stay at 10750 if you are using a standard ku lnb
changing the frequency to 10000 will not work.
Johncomp,
Ynnedibanez is absolutely correct with the statement above. If your LNB has a L.O. frequency of 10.750 GHz, then you MUST set your parameter in the receiver to match this.
Setting it to any other frequency is totally meaningless, even if you appear to detect a signal level/quality. It is a bogus reading and you should not pay any attention to that result.
Certainly I assume that you would like an explanation of why you detect a reading with an improper L.O. frequency setting (10.000 GHz). With a lack of the precise reason, I can only surmise that it (the receiver) is detecting background noise from the amplifier's own internal circuitry (within the LNBF). Setting the LNB frequency to an incorrect value within the receiver's menus might allow you to detect some sort of oddball harmonic that is NOT associated with any satellite signal.
I know that it looks good to you to see a positive reading on your receiver's meter scale, but it isn't reading anything that is valid. You must ignore this as it is not useful information. It is a bogus reading.
Do NOT try to change the LNB 's L.O. frequency. If it is listed on the LNB to be 10.750 GHz, then you must set it that way in your receiver's menu. You cannot change its "spots".
If it is a zebra and has stripes, then you must tell the reciever that you have a zebra. If it is a leopard and has spots, then you have to tell the receiver that it is a leopard.
I know that sounds a bit silly, but it is just the way it sounds. It is either this or it is that, there is no in-between. The L.O. or Local Oscillator within the LNBF is preset to one frequency and it CANNOT be altered. Whatever frequency that is, (10.750, 9.750, 10.600 or other) you have to tell the receiver what it is so that the receiver knows to look for the appropriate "beat frequency" or the result of the difference between the L.O. frequency and the incoming satellite signal frequency.
This does not matter (regardless of the receiver make or model that you have). It is dependant soley upon the LNBF that you are using.
