window as well as the „Input
Stream Identify“ field with a
choice of one or more numbers
that indicate each of the
existing transport streams
from that transponder. Here
you simply choose on one of
the choices and then click
on one of the entries. At this
point you can exit out of TS
Recorder and a scan of the
desired MIS frequency in the
DVB reception software results
in the desired stream.
This procedure can be repeated
as often as necessary
until all of the streams
shown in the „Input Stream
Identify“ field have been selected
and processed. And
there you have it! With each
newly selected stream, the
DVB reception software recognizes
completely different
channels all on the same frequency.
Another more comfortable
option to use is ProgDVB
(www.progdvb.com), that in
its current version can work
with MIS frequencies without
any extra help or external
tools; even the free
standard version can do it.
For our actual tests we
used the 12718 MHz transponder
on EUTELSAT 12
WEST A at 12.5° west on
which there are four transponder
streams that are
totally independent from
each other. We had no trouble
accessing the completely
different channels on each
individual transport stream
as well as switching between
the streams. Naturally, all
of the features you‘re used
to seeing, such as EPG and
language selection, are all
available with MIS reception
except that now multiple
transport streams can be received
on one and the same
frequency. It was also worth
checking out the 11914H
transponder on ASTRA 1G
at 31.5° east where there
are a total of three different
transponder streams carried
on a single frequency. Here
too our test of MIS reception
using the TBS QBOX 5925
worked perfectly. And the
relatively high symbolrate of
35610 Ks/s used on EUTEL-
SAT 12 WEST A‘s 12718 MHZ
transponder did not create
any problems.
In addition to MIS reception,
Tenow also developed
a BlindScan tool for the TBS
QBOX 5925‘s tuner that
proved itself quite capable
in our tests. Just about eight
minutes was needed to identify
120 active transponders
on the HOTBIRD satellite at
13° east; that‘s a few more
than you might find in many
frequency lists.
The BlindScan tool can be
customized by the user to
his specific needs. Whether
you want to search a specific
frequency range, one
polarization or just a single
band, you‘ll find all of the
necessary settings capabilities
presented in an easy
to understand format. The
results of a BlindScan can
be easily exported to a file
which can then be imported
and utilized by, for example,
DVBViewer or ProgDVB.
In our tests the TBS QBOX
5925 showed us that with its
BlindScan it was quite capable
of correctly and reliably
recognizing and processing
transponders with very low
expert
OPINION
+ ● Excellent workmanship
● Powerful tuner
● Manufacturer‘s own tools to optimize all of the TBS QBOX
5925‘s functions
● Perfect MIS reception with the help of the free ProgDVB version

● None
TBS QBOX 5925
USB Receiver for MIS
symbolrates as well as those
transponders that were very
close to each other.
The TBS QBOX 5925 is a
many-facetted and practical
DVB-S2 receiver for the PC
and thanks to its exceptional
tuner can easily handle weak
or narrowband signals. MIS
reception with VCM/ACM is
a feature that for now is really
only important to satellite
enthusiasts but, because
of its significant cost savings
potential, will without a
doubt also become interesting
for everyday users in the
future.
