new channel lists and up-

As soon as you call up the
spectrum display in DVB-S
mode the meter immedi-
ately displays all pre-stored
satellite entries, which in
our case comprised 26 of
the most popular orbital
positions between 75° East
and 30° West. The LOF of
the used LNB can either be
selected from a list of stand-
ard values or can be entered
manually – hats off to that
convenient option.
Users of SCR unicable so-
lutions will be very pleased
to find out that the manufac-
turer does not leave them in
the dark either by offering
all required parameters for
selection. The new Baotong
meter comes with all control
adjustment options, such
as DiSEqC 1.0, 1.1, 1.2, 1.3
and toneburst.
The pros among our read-
ership will surely have con-
cluded from DiSEqC 1.2 and
1.3
that the meter must
definitely be compatible
with DiSEqC motors, and of
course they are absolute-
ly right. The WS-6936 is a
perfect match for motorised
antennas and will control all
movements as required.
Thanks to the manufac-
turer pre-installed tran-
sponder database the meter
allows selecting a specific
frequency even before the
spectrum is displayed. In
such a case the frequency
is called up directly and
locked. Users can select any
bandwidth between 108 and
540
MHz or may opt for full
spectrum display instead.
The same is true for the
polarisation and the 22 kHz
signal, which can be set or
changed with a single touch
of a button. Thanks to the
function keys below the
screen users can adjust
bandwidth, polarisation and
frequency band settings on
the fly, without having to
make a detour via the set-
tings menu.
Once the required fre-
quency is marked with the
help of the arrow keys –
with Up/Down changing the
y-axis of the display and
therefore the signal level
scale – a press on the F4
function key initiates a sig-
nal search.
We noticed during our
test that the spectrum dis-
play reacts very swiftly to
any signal changes. This is
particularly important for an
initial rough antenna align-
ment, and we cannot praise
such immediate feedback
highly enough.
If you need access to all
adjustment options for sat-
ellite reception/signal meas-
uring the DVB-S entry in the
main menu will open that
door for you. Here you can
edit satellite and transpond-
er lists, start signal scans
and rename, change, add
or delete individual satellite
and transponder entries.
The sky’s the limit, and we
mean it.
Using the Quick Search
function you are able to
perform a manual chan-
nel search on a pre-defined
frequency. It goes without
saying that all adjustment
