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.+

Today's world is complicated enough.Therefore
the supreme development goal of the DiRaWave 032 was easy operation besides maximum
Only two connectors are needed:
Antenna connector (BNC)
USB plug for PC
USB is used for data transfer and
providing power. The receiver is recognized as external audio device. No special
drivers are needed. Therefore the installation process is fast and fully automatic.
Due to the compact design in combination
with the integrated USB power supply the receiver is an ideal companion for portable
Simply connect an antenna and start listening right away!
The DiRaWave 032 emerged from a cooporation
with the german special software developer Bonito who is responsible for the firmware
and control software while we are competent for hardware development, production
With decades of experience valuable
synergies were accomplished.
The DiRaWave 032 hardware is identical
to the Bonito RadioJet1102S. The only difference is the performance of the available
While the DiRaWave 032 is offered
with the freely available basic control software RJ10Mini as a standard feature,
the RadioJet 1102S is delivered with a more complex and extensive control software.
Nevertheless it is also possible
to purchase the RadioJet software afterwards.
The standard RJ10Mini control software
allows the complete instrument control and demodulation of all commonly used forms

A real-time spectrum and waterfall
display is also included.
Moreover, an extrnal IO-DLL (ExtIO-DRW032)
is also available, so that all third-party SDR programs are supported which allow
the integration of an external IO-DLL like WinRad, HDSDR, SharpSDR etc.
Quality instead of quantity
While the general trend for PC-controlled
receivers is towards capturing large bandwidths, the DiRaWave 032 works deliberately
in the opposite direction.
A good receiver should always get
the most from a certain input signal. Because strong and weak shortwave signals
have to be processed at the same time broadband concepts are reaching their limitis
especially when using high-performance antennas.
If, for instance, phantom signals
occour late at night on frequencies above 20MHz even though the Maximum Usable
Frequenncy (MUF) has already dropped significantly, this indicates intermodulation
problems of the used receiver.
Our concept is a narrow band concept
which uses besides ultra linear mixers also a special steeply sloping bandpass
crystal filter to enable optimum useful signal processing for further digitization.
Especially for weak signals close
to the noise floor more than average results are achieved, so that even the weakest
stations can be captured and recognized.
In addition to the low power consumption
of just over 200mA, the demands on the connected PC are also modest, so that operation
with the most common netbooks is already possible.

Thank you very much for the speedy
delivery of a DiRaWave032. It arrived in good condition.
The DiRaWave032 is now my fourth SDR in my shack, although strictly speaking the
DiRaWave 032 is no SDR in the conventional sense.
I would like to tell you that you
had a smashing success with the DiRaWave 032. The mere fact that there is no classic
AGC results in there being no 'pumping' of the signal in the first place and that
is why the noise floor was lowered by 1-2 steps. Super!
The receiver characteristics, the sound and the intelligibility can be called extraordinary,
especially in connection with the free HDSDR-software (current version 03.2013)!
Without doubt, the DiRaWave032 has high sensitivity with a very good S/N ratio,
provided a good sound card (for playback) is made use of.
Furthermore, the large signal immunity is outstanding. Even signals on the 160m
band received with a quarter-wave antenna (41m half-square) do not overdrive the
I totally agree with you statement: "Better than average results are achieved
especially with signals at the threshold of the noise floor so that even the most
quiet stations can be received."
In sum, super receiver! Simple operation,
no external power supply necessary.
Really great! A lot of receiving
power for the current purchase price of 499, 00 Euros.
