You won't believe your ears!
The new Bonito shortwave receiver RadioJet 1102S combines innovative design with the advantages of modern computer technology. It has a frequency range of 0,04 MHz to 30 MHz with an excellent sensitivity of .03 µVolts on a noise level of -137 dBm with an extreme resolution of 144 dB at a bandwidth of 24kHz. The Noise floor is extremely low, because there are no active parts between the Antenna and the ADC.
Strictly speaking, this radio is no SDR, although it is exclusively controlled by computer. So far 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 IM jack 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 seems to the expert as if some elements are missing which so far have defined a receiver.
For example, there is no AGC but three digital output channels with different signal levels. Each of these channels has -15dB ATT and can amplify or attenuate the input
from -16 to +45 dB continuously. The complete large signal is scaled in 144 dB and can be read at the same time on a scale of 48 dB via the high resolution DX-channel.
This receiver can process an extremely weak signal without another signal being attenuated in its neighborhood. In this way, no strong transmitter can suppress a weaker
one or can over modulate the receiver to such a degree that the signal becomes unintelligible.
During the development of this receiver special attention was paid to an intelligible rendering of the signal so that you cannot only view dB's in the spectroscope but can
listen to a normal QSO. The reception reports of the Bonito RadioJet will convince professionals and shortwave listeners alike.
On the one hand, no completely new technologies were used, but on the other 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 center piece of this IF-receiver is the supplied software. It makes all the different applications possible. An IF-Input-Device is built into the RadioJet so that the radio is
like an external USB-Audio recorder and an easy installation without a complicated driver is assured:
Simply plug and Play
The receiver comes with the standard Software and the following features:
Reception and recording of transmissions in USB, LSB, CW, AM, FM and DRM. All filters are completely variable and can have their waviness and notches drawn by hand
with the equalizer. 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
