USB-controlled 3 Way Active Antenna Swich and Mixer
9KHz - 300MHz
With the DiRaSelect 300 we
expand our product range of receiver accessories by an additional component. Via
USB up to three different receiving antennas from 9 kHz - 300 MHz can be switched
loss-free to one output socket.
High sensitivity and
excellent strong signal handling
With the DiRaWave 032 we introduce the third generation of PC-controlled shortwave
receivers from own development and production.
An extremely low noise floor of -137dBm
in association with an oustanding intermodulation-free dynamic range of >102dB
combines perfectly maximum sensitivity with excellent strong signal handling.
Universally usable: Generating
DRM & Analog AM Broadcast Signals with SPARK Modulator & DiRaGen 30 USB
With the DiRaGen 30 USB we present a further variety of our shortwave exciter
which is completely USB-controlled in combination with the modulator software SPARK.
With this unbeatable combination
of software and hardware it is possible to generate all commonly used kinds of
shortwave broadcast signals.
DiRaGen 30 - Generating Shortwave DRM Radio Signals
Transmitter software for generating a DRM signal
via PC & sound card is already available.
Our new developed exciter DiRaGen 30
converts such a DRM signal to an individual shortwave frequency.
SoDiRa supports DRB 30 & 32
The actually most
comprehensive free SDR software SoDiRa supports from version 070 direct frequency
tuning of our PC-controlled receivers.
We have added an extra section concerning support
of the DRB 30
and DRB 32.
DRB 32-4 at the Arkala Extremes Project
This special model
consisting of 4 coherent DRB 32 receiver units for simultanious 4-channel reception
for measurements of the possibly
highest 14MHz antenna in the world at Arkala/Northern Finland since July 2007.
These data are needed to create a mathematical
model for antenna simulation. Design goal is development of "intelligent antennas"
which deliver always the highest available signal-to-noise (SNR) ratio.
DRB 32 at the International Broadcasting Convention (IBC)
Our new semiprofessional DiRaBox DRB 32 will
be showed up at the DRM - EBU Village Stand # 10-411 IBC 2007 from 07 - 11 September
2007 in Amsterdam/NL .
DRB 32 - New DiRaBox
With the new DRB 32
we introduce a modified concept especially for semiprofessional applications with
Increased sensitivity of about 6dB
Switchable high intercept range (HighIP) for large signals
Further improved selectivity
Expanded interface with additional reset
12KHz standard IF output
DRB 30 PREMIUM - 1st prize in real-world test
A test of the DRB 30 PREMIUM in comparison
to two other SDR receivers under DX conditions is available here:
King s Village DX Tests: Can a 150 Grams Box be a Communications
The test was made in Finland, DX
stations were Radio New Zealand & Wantok Radio Light in Papua New Guinea. Short
excerpt from the conclusion: "...
the small box is really capable to receive signals as good as more expensive models."
DiRaRem - Frequency database management for
DiRaRem allows easy frequency tuning
using different frequency listings. This software was first developed by our customer
Frank Deinhard for his own purposes and is now available
for common use.
New control software & USB adapter for
A new Control Panel software version
V1.5 is available. And also a new plugable USB adapter
which allows control of the unit via USB bus.
DRB 30 - Test report concerning DRM reception
with the new 2006 model
A new comprehensive DRM reception
test report is now available. Rainer Suckow who runs the DRM website section of
the Funktechnikmuseum Koenigs Wusterhausen ( birth place of broadcast in Germany
) has written a voluminous test report regarding the new DRB 30 model at many
different daily reception conditions.
DRB 30 - Single sample achieves max. 49.5dB
SNR DRM performance
After a AGC modification of the DRB
30 the DRM performance was measured in combination with the DREAM software. The
best sample achieved 49.5dB SNR, the other samples were in the range of 38 - 46dB
All units of the 2006 model series
already include this modification, elder units are upgradeable.
DRB 30 test report in FUNKAMATEUR 01/2006 issue
In January issue the German ham radio
magazine FUNKAMATEUR has testet the DiRaBox DRB 30 in combination with Software
Defined Radio applications.
How to build a simple active antenna for the
Simple but efficient: Only four components
are necessary to construct this simple
active antenna suited for the DRB 30. The receiving range
is from AM to FM (0.5 - 100MHz) with good performance.
New product range - PC-controlled Shortwave
Receiver DRB 30
The DiRaBox (Digital Radio Box) DRB 30 is a PC-controlled black box shortwave receiver
developed for Software Defined Radio (SDR) applications. Innovative technology
and state-of-art design combined to form a RF frontend for all freeware and commercial
SDR software applications.
DILAN 2150 - New firmware V4.2
The DILAN2150 Satellite Level Meter
is now available with 32 instead of 16 programmable memory channels.
SpectraBox SAT DX special model for EGIS-Rotor
The well-kown EGIS-Rotor positioner
has an analog input (AGC) for signal-strength dependent positioning optimization.
We can offer now a special model of the
SpectraBox SAT DX with an additional signal-strength dependent voltage.
Together with the Auto Resume firmware
this model is optimized for the EGIS-Rotor positioner.
SpectraBox SAT DX available with Auto Resume
For professional applications we
offer now the SpectraBox
SAT DX also with a special firmware called Auto
The Auto Resume version stores automatically
all selected parameter settings. These settings will be automatically selected
after powering-up .
New model: SpectraBox ISM
The complete spectrum range of wireless
communications from L to ISM-band is captured by this analyzer.
This multi-purpose instrument handles numerous applications:
From precision field strentgh measurements to wireless video bug detection.
New model: SpectraBox SAT DX
Basing on the reliable SpectraBox
SAT standard model we introduce with the DX model a version with extended capabilities:
Additional DX mode for higher sensitivity
Four programmable converter LO
Higher frequency zooming resolution
including zero-scan (0MHz/DIV)
Visible basic noise level
Higher dynamic range
A data sheet is available here.
It is also possible to upgrade the
SpectraBox SAT standard version, but this
requires a new calibration. More details
