You won't believe your ears!
The Bonito shortwave receiver RadioJet 1102S combines innovative design with the advantages of modern computer technology. The frequency range is from 40 kHz to 32 MHz with a minimum detectable signal at 3 dB above noise at -134 dBm (DNS). It is linear over the 16 kHz signal width, which then is displayed on a 24 kHz enlarged spectrum for assessing the quality of the filter. The noise floor is extremely low because there are no active parts between the antenna and the ADC.

Strictly speaking, this radio is not an SDR, although it is exclusively controlled by computer. As far as we know, no SDR has defined, controlled, read or computed anything like the RadioJet. Bonito RadioJet is a short wave receiver with a built-in USB audio device and a 24kHz multi-channel IF-Input or to put it simply:

The most obvious application of modern radio technology.

The electronics of this receiver has such a high integration density that it may seem to the expert as if some elements are missing which normally define a receiver. For example, there is no AGC, but two digital output channels with different signal levels. Each of these channels has -15 dB ATT and can amplify or attenuate the input from -16 to +45 dB continuously. The entire signal is placed into position in the RX channel as a 144 dB scaled signal. Simultaneously, a ~40 dB stronger signal is offered via the high resolution DX-channel. This receiver can process an extremely weak signal without another signal being attenuated in its neighborhood. Thus, no strong transmitter can suppress a weaker signal or can overmodulate the receiver to such a degree that the signal can no longer be read.
A new experience in listening
During the development of this receiver, we paid special attention to the audio signal quality; you will hear a high quality audio and you will also see the result in dB in the high resolution spectrum (1 Hz). The excellent audio quality of the Bonito RadioJet will convince professionals and shortwave listeners alike.

Hearvolutionary the new Bonito RadioJet 1102S SDR Receiver

No completely new technology was used, but we implemented a totally new understanding of electromagnetic processes. In order to create a new receiver generation, the new physical theories of bonitistic geometry were used successfully. The result is a very high IP3 (+29 dBm), excellent dynamic range (96 / 136 dB), outstanding sensitivity of 0.03 ÁV on a very low noise floor MDS -134 dBm and 1 Hz tuning accuracy. With these key features and its versatile software the RadioJet 1102S is probably the most innovative IF-Receiver on the market at an affordable price.

Real Plug and Play
Based on our years and years of work with various USB receivers, it was clear to us that a complicated installation results in frustrated customers. Developing the RadioJet, it was our aim to make the installation as easy as possible. An IF-Input-Device is built into the RadioJet so that the receiver is like an external USB-Audio card and easy installation without a external driver installation is assured.

Good software replaces expensive hardware

Bonito RadioJet Software SDR Receiver

The center piece of this IF-receiver is the included software. The standard software is already very extensive and is geared to the casual listener as well as well as experienced DXers. It was designed for those who want to get a bit more out of a signal without constantly having to start additional software. The user interface of the RadioJet is very similar to a professional receiver and is divided into several layouts. There are zoomable spectrum analyzer configurations in high resolution. Depending on the layout, you will see displays of the frequency, the filters, spectrum in 2D or 3D or waterfall displays. In addition, you will find all the controls match the layout and operating mode. The receiver’s selectivity, IF shift, passband tuning, notch and all other functions can be adjusted with the mouse cursor. It contains all necessary features such as many different noise reduction modes, memories, squelch (including the new SNR-Squelch), many tuning options, and a wide choice of different demodulation modes including DRM.

The receiver comes with the standard Software and the following features:
Reception and recording of transmissions in USB, LSB, CW, FM and DRM. DRM Decoder, MRSS. All filters are completely variable and can be manually adjusted. S-meter and spectroscope have an extremely accurate dBm-scale and can be calibrated

Technical data
It is common to compare the technical data of receivers. However, with most digital devices the data cannot be compared. Certain features of hardware and software definitions make this impossible. For example, values are shown in dB or dBm according to the analogue principle, although this principle is no guarantee for a good audible signal.

For a better understanding: 160 dB would be a fantastic value for any receiver. But this fantastic number becomes impossible, if you scale the variable data in 10 dB steps up to 160 dB and have 16 different values. You will understand immediately that the signal cannot be decoded understandably neither acoustically nor phonetically.

Unfortunately, this occurs quite often with SDR's and even dB experts including their measuring equipment can be fooled. As soon as a 14-bit ADC is used, nobody wants to accept that even 16384 data (84dB) are no guarantee for intelligibility, even if the data are taken from one scale which is divided from 0-144dBm. In this way, the impression is created that you can convert a 144 dB signal from a 84 dB signal which is comparable to an infinity scaled analogue signal.

So, before you start comparing things, it would be good idea to get some information on digital comparison criteria, such as: good to know about SDR's von DG2OY
