We
have all seen the "Signal Strength" meter when you go into
"Services" then "System Set Up". The signal strength
indicator will work on most satellites and the signal quality meter will
register only on a few satellites. They will not tell you that you are on
the Sky digital satellite (Apart from going to the listings and seeing if
the channels work) neither will they tell you that you are receiving all
of the four Sky digital wavebands correctly. The indicators are based on
an overall signal strength and quality.
Here is how to do it! The previous section "How do we receive
the signals?" dealt with how they are transmitted, here is how you
can test each of the four incoming signals. Go to "Services"
press 0,1 then select this will take you to the installers menu, go to
"Manual tuning". Enter the following information:
 | Frequency 10.862H, symbol rate 22000 (or 22.0), FEC 5/6 and press
select. This is the low band horizontal channels which covers most of
the Disney channels.
| Now try 10.906V, 22000, 5/6 and press select. This is the low band
vertical channels which at the moment is broadcasting some ITV
variations, Grampian, Scottish ITV etc.
| Now try 11.914H, 27500, 2/3. High band horizontal channels currently
broadcasting Premier & Moviemax 2 & 3.
| Now try 11.934V, 27500, 2/3. High band Vertical channels currently
broadcasting Sky Sports 1,2 & 3.
This test will ensure that all four wavebands from the Sky digital
satellite are being received OK. Note that the Network ID remains the
same (Currently 0002), yet the transport stream will vary as
alternative transponders are being selected from the satellte. The
lock indicator should be on OK for all four signals. If you wish to
view any of these channels, press the yellow button to store them and
go to "Services" then "Other channels" where they
can be selected.
A problem we have come across several times are where all channels can
be received apart from the Disney package. This is usually where the
LNB does not revert to the low band (or has a limited bandwidth) and
instead remains permanently in the upper band. Replacing the LNB with
another "Universal" LNB usually cures the problem, please
also note that these lower band channels broadcast from Astra 2D
satellite which has a narrow UK beam. The above test will clarify that
the receiver and LNB are operating correctly. NB: We will be
publishing the full channel listings soon. |
