Skystar 2 PCI always weak or no signal

[khalidomar]

I recently obtained a SkyStar 2 PCI card and installed it on my computer (Windows 7 64bit). I'm using SkyStar driver version 4.6.0.9999 and driver seems to be working fine.

My dish is 180cm diameter with one single output LNB which was connected to my Dreambox 500s, so I went and bought another LNB which has two outputs and replaced the old one. I connected one of the outputs to my dreambox and the other output to the SkyStar 2 PCI card.

My dreambox detectes very good signal on Nilesat 7W (SNR=94%-97%, AGC=89%-95%, BER=0%) and I never have problem with any channel or transponder.

However, with the Skystar 2 PCI, the quality of the signal is much less or no signal at all! For some transponders, the signal quality is barely 44% and signal strength is barely 75% while for other transponders I get no signal at all and I can't watch any channels.

I tried ProgDVB Pro, and DVBViewer TE2 and I got same results.

Anyone knows what why would the SkyStar 2 card show weak or no signal and how to fix it?

The screenshots below show the signal quality for various transponders and the various settings I have for ProgDVB and Setup4PC

Re: Skystar 2 PCI always weak or no signal

Hi again, I was playing with the settings here and there and finally changed the "switch" value of the LNB settings from 11700 to 13000 (just a guess). And suddenly most of the channels that were previously showing no-signal are now working with 80% quality. Still, some other channels do not work! Strange, but that is what happened

I noticed that most of the transponders that do not have signal are in the range 12000 MHz and above, anyone has an idea what is wrong given that my dreambox 500s is connected to the same LNB (different output of course) and is working great with all transponders and channels?
