The Bonito 1102S RadioJet - Click to Enlarge

Universal Radio has published the price of the Bonito 1102S RadioJet at $699.95 US and they are taking orders.

Universal’s price is  $300 less than that of the Microtelecom Perseus ($999.95 US) and the $200 less than the WinRadio Excalibur ($899.95 US).

After reading Fernando’s review of the RadioJet–where he compared it to the Perseus–this may be one of the best SDR performers for the price. We will be reviewing the Bonito 1102S RadioJet in the near future as well.

RFSpace-CouldSDRThe CoudSDR is the latest offering by the US-based SDR manufacturer, RFspace. At time of posting, the CouldSDR is in beta testing, but expected to ship to consumers in 2015.

The CouldSDR represents a step to make SDR over Internet much easier to implement. Indeed, RFspace describes the CloudSDR as, “The next chapter in connected Internet of Things radios.”

The Cloud SDR can be used as a traditional computer-connected SDR, much like the RFSpace NetSDR, but with a 1 MHz bandwidth window. The CoudSDR is also a self-contained server that can stream bandwidth video and received audio over the Internet, allowing remote control via a Remote SDR Client or even via a smart phone app.

RFSpace has published a comprehensive PDF brochure about the CloudSDR. You can download the brochure by clicking here.

Features (subject to change):

  • Wideband spectrum analyzer mode offers 56 MHz wide spectral captures in both 2D, 3D and waterfall formats.
  • 9kHz low end frequency range allows SONAR, VLF and ultrasound applications.
  • External 10 MHz reference input allows multiple radios to be locked to the same frequency reference like Rb, Cs and GPS disciplined oscillators. An internal TCXO takes over when no external reference is detected.
  • The CloudSDR has both external and internal triggering modes for synchronization of multiple radios as well as triggering at specified intervals. The internal trigger mode allows the phase to be adjusted, as well as the frequency in steps of 1nHz.
  • The built-in remote server allows the CloudSDR to be placed anywhere in the world. A PC running Windows, Linux, Android or MacOS is able to access the radio with very low latency. It does not require a PC at the server side and the server is available within 10 seconds of boot up.
  • An Android application has been developed to access the CloudSDR in remote mode. In addition, an open source client is available license free for Windows, Linux and MacOS. Programming is extremely easy since all of the DSP, FFTs and scaling are done inside the radio.
  • The demodulated audio is available at the radio side to monitor or record the audio. The audio port switches to a 192 KHz capable analog I/Q output when in I/Q streaming mode.
  • Optional 1 GS/s digital upconverter and signal generator can generate modulated and CW signals remotely or direct connect in the 100 KHz – 455 MHz ranges. Specs TBD.

The Cross Country Wireless SDR-4

The Cross Country Wireless SDR-4 is an affordable SDR (software defined radio)  covering the HF spectrum from 0.85 to 30 MHz. It features a Si570 low noise synthesised VFO, relay switched band pass filtering, a power FET RF amplifier and a built-in USB soundcard.

The price of the SDR-4 is £149.95 plus shipping from the UK.

Specifications/features (per manufacturer):

  • Antenna isolation transformer with a 50 or 450 ohm impedance input for use with coax fed antennas or random wire antennas
  • Extra antenna isolation when the receiver is powered down
  • Relay switched RF band pass filters
  • RF amplifier using a power MOSFET in the receiver front end
  • Internal 10 MHz RF level calibration oscillator
  • Built-in USB stereo soundcard
  • 3.5mm soundcard audio output for headphone monitoring or connection to datamodes program
  • Built in a compact aluminium case 175 x 106 x 30 mm

The Bonito 1102S RadioJet - Click to Enlarge

Universal Radio has published the price of the Bonito 1102S RadioJet at $699.95 US and they are taking orders.

Universal’s price is  $300 less than that of the Microtelecom Perseus ($999.95 US) and the $200 less than the WinRadio Excalibur ($899.95 US).

After reading Fernando’s review of the RadioJet–where he compared it to the Perseus–this may be one of the best SDR performers for the price. We will be reviewing the Bonito 1102S RadioJet in the near future as well.

RFspace Cloud SDR

RFSpace-CouldSDRThe CoudSDR is the latest offering by the US-based SDR manufacturer, RFspace. At time of posting, the CouldSDR is in beta testing, but expected to ship to consumers in 2015.

The CouldSDR represents a step to make SDR over Internet much easier to implement. Indeed, RFspace describes the CloudSDR as, “The next chapter in connected Internet of Things radios.”

The Cloud SDR can be used as a traditional computer-connected SDR, much like the RFSpace NetSDR, but with a 1 MHz bandwidth window. The CoudSDR is also a self-contained server that can stream bandwidth video and received audio over the Internet, allowing remote control via a Remote SDR Client or even via a smart phone app.

RFSpace has published a comprehensive PDF brochure about the CloudSDR. You can download the brochure by clicking here.

Features (subject to change):

  • Wideband spectrum analyzer mode offers 56 MHz wide spectral captures in both 2D, 3D and waterfall formats.
  • 9kHz low end frequency range allows SONAR, VLF and ultrasound applications.
  • External 10 MHz reference input allows multiple radios to be locked to the same frequency reference like Rb, Cs and GPS disciplined oscillators. An internal TCXO takes over when no external reference is detected.
  • The CloudSDR has both external and internal triggering modes for synchronization of multiple radios as well as triggering at specified intervals. The internal trigger mode allows the phase to be adjusted, as well as the frequency in steps of 1nHz.
  • The built-in remote server allows the CloudSDR to be placed anywhere in the world. A PC running Windows, Linux, Android or MacOS is able to access the radio with very low latency. It does not require a PC at the server side and the server is available within 10 seconds of boot up.
  • An Android application has been developed to access the CloudSDR in remote mode. In addition, an open source client is available license free for Windows, Linux and MacOS. Programming is extremely easy since all of the DSP, FFTs and scaling are done inside the radio.
  • The demodulated audio is available at the radio side to monitor or record the audio. The audio port switches to a 192 KHz capable analog I/Q output when in I/Q streaming mode.
  • Optional 1 GS/s digital upconverter and signal generator can generate modulated and CW signals remotely or direct connect in the 100 KHz – 455 MHz ranges. Specs TBD.

Quadrus-SDR

The Quadrus SDR is a new military-grade SDR with phase-coherent multi-channel capabilities with up to 16 channels, which means that it can be used for direction finding, diversity reception, as well as MIMO applications.

While the Quadrus line is aimed squarely at government and scientific research markets, the $1490 US Quadrus DRU-244A-1-1-PCI, a four-channel SDR, might appeal to the discerning DXer, amateur radio operator, or radio experimenter.

The Quadrus SDR is currently available as three models:

SAGAX DRU244A-1-1-PCI (Click to enlarge)

SAGAX DRU244A-1-1-PCI (Click to enlarge)

DRU-244A-1-1-PCI SDR hardware digitizer $1,490 US

  • 1 one ADC chip with 1 analog input
  • 1 one DDC chip with 4 radio channels

DRU-244A-1-4-PCI SDR hardware digitizer $1,990 US

  • 1 one ADC chip with 1 analog input
  • 4 four DDC chip with 16 radio channels

DRU-244A-1-4-PCI SDR hardware digitizer $2,490 US

  • 4 four ADC chip with 4 analog input
  • 4 four DDC chip with 16 radio channels

We will post technical specifications as the become available.
