Knowing what satellite we are on
And the
HD
RANGER
Lite
comes into action. Our dish is now more ore less
"looking" in the direction where we presume our "bird" is parked. With the
HD RANGER Lite
connected to the output of the LNB we select satellite
frequency range, antenna alignment mode, span of 200 MHz and set the power
supply voltage to one of the possible values. We will take for example 13 VDC,
which will take us to the VERTICAL polarisation and LOW band. We can use
80 dBµV for the reference level for we can change that at pleasure depending on
the amount of signal we get.
Something will come up on the
HD RANGER Lite
screen. It will normally be a
weak signal that July come from the desired satellite or from the neighbour ones
for the dish is not properly tuned up yet. Swing the dish slightly horizontally and
vertically until a decent signal is shown on the screen.
There we have a satellite but which one is it? Most probably the signals we are
looking at are digital transponders from the unknown satellite. The
HD
RANGER
Lite
can be operated in frequency or channel modes.
Tune any of those digital channels in frequency mode using the joystick and the
markers shown on the screen. The
HD
RANGER
Lite will tell you what satellite
and/or orbital position you are on in a matter of seconds !
If we are unlucky and this is not the satellite we want then we only need to move
the dish slightly to pick the signal from the next satellite and repeat the process.
