got a dreambox dm800s hd, latest gemini image.  got a dual headed lnb on skydish,  can tune C1 and get a solid signal, but D1 is fluctuating up and down, resulting in channels pixialting and not displaying properly.  i  have lof/h 10750, lof/l 10750, and threshold 10750 with 22khz tone off for D1 and on for C1. I have tried so many other settings from various forums with no luck.  my other dreambox a dm600s works no problems at all and i copied the settings from that box, could anyone explain why i cant get the dm800 to work on D1?  If i cant get a solid signal on D1 im just going have to unbolt the dish and swing it around just a touch to the other side so the lnb hits D1 instead of C1 as set up by sky, then set 22khz to off for D1 instead of being on and delete C1 all together, i know that will work, either that or swap to a 11300 single lnb.

Hi Gareth41,

I'm confused! You say that you have the "22Khz tone set off for D1 and on for C1" (which it should be), then you state that you might swing the dish back how Sky had it (which is how it should be now if you want D1 & C1) and "set the 22Khz to off for D1 instead of being on".  - - -??  Please clarify.

Cheers  Wild Bill

Sorry I mean change the dish alignment from how sky sets it, moving it sideways just a touch so that the half of the lnb which is pointed at C1 is then moved and pointed at D1 instead, hence the 22khz tone is then set to "on" instead of "off" to get signal from D1, the other half of the lnb where the 22khz tone is set to "off" and was previously pointed at D1 now points no where, ie is not aligned with any satellie.

Hi gareth41,

Right, I follow you now. Therefore I'd suggest you check the skew on the LNB. It's quite critical on those dual LNBs for D1 because you've got both polarities present, but not so critical for C1 as you're only using the vertical polarity. - but D1 & C1 do work very effectively off that dual LNB when it's lined up correctly. 

Cheers,  Wild Bill.
