Hi,

 

Back to your topic I saw the symbol rate (44995) used on the mentionned TP and I am quite sure that those high value are not supported by the VU+ tuners.

I read something about it, google for "high symbol rate VU+" and you will see that you are not the only one to report such issue.

Really?

 

Are all people complaining here about the same issue wrong?

Yes. Their LNB is skewed wrong. When transponder frequency is identical in both polarisations LNB skew needs to be perfect.

Plug in your analyser. Lock one polarisation. Skew for maximum MER. Obviously you need a proper analyser though because right now you aren't even getting signal lock, so you can't do it with the STB.

i am sorry to say that i am getting signal with strength 90% and snr 90% so it means it is no skew issue i guess. lot of other people face same issue

The VU dual tuners are by far not as good as the single tuners. Do you have a single tuner to test & compare?
