First of all, ignore what I said above re blind scan, I had forgotten that you are using an Elite, however I'm confused by your response that sounds like you may have done a blind scan and came up with different SR, which isn't possible with an elite since you have to specify the SR.
Basically, you have me completely confused relative to what you are saying you are trying to do, how you have your lnbf connected (ie through switches or with one line, using the jumper on the lnbf, assuming it has that) what parameters you're entering or what you are saying happens. ?
I thought that you couldn't lock C-band, but now it sounds like you're saying it's working on C-band? Before when you said that "when i go to 9750/10750 works every time", I asked for what you mean by it works, and you tell me something about C-band, when the 9750/10750 only refers to Ku band, so I don't know what you are saying. Basically, the first step is to figure out which lnbf you have, and that requires info on what Ku transponders you are able to lock with what settings. If your lnbf is the universal version, which I think the -2 version is, then 22khz is used to switch from the low ku band to the high ku band. In the US, you're probably not going to find anything in the low band, so Ku wouldn't give you anything unless 22khz was on. If it IS the universal version, the Ku freqs would be off by 150 if you're using the 10750 setting. For C-band, you wouldn't use any of those settings, ie you'd use 5150, not universal or 9750/10750. If you have the universal lnbf, and you haven't selected a diseqC setting, it is unknown what port if any it would put you on.
Anyway, I think you need to say more about exactly what you're doing, what is working, what isn't working, what settings you're using when it works, what settings you're using when it doesn't work, what transponders you're trying to lock when it works and doesn't work, etc. I can't figure out what you're doing.
