The next chapter in #connected software defined radios.


The Cloud-IQ is the latest high performance software defined receiver from RFSPACE. The Cloud-IQ offers two modes of operation. The IQ mode, offers 24 bit, IQ streaming to the PC over ethernet. This mode uses our SpectraVue software or third party programs like SDR-Radio, SDR# and GNU radio. The stand-alone “Cloud” mode includes a built-in internet server. In this mode, the radio performs the tuning and demodulation of signals and transmits the demodulated information back to a PC, OS-X, Linux or Android client anywhere in the world.

How does it compare to the SDR-IQ:

  1. -Cloud-IQ offers 1.8 MHz IQ sample rate vs. 196 kHz of the SDR-IQ. Uses ethernet interface vs. USB. Can be placed far away from the computer or anywhere in the world.

  2. -High resolution decimator with 24 bit output resolution.

  3. -Sensitivity is over 15 dB better.

  4. -Broader frequency coverage of 9 kHz to 56 MHz mode.

  5. -Includes low bandwidth cloud mode for access anywhere in the world.

  6. -Powered by a small power supply or USB powered.

  7. -Includes an internal adjustable trigger for capture of repetitive signals (pulsars, CODAR, chirps).

  8. -2 antenna input ports for remote or local selection of two antennas.

  9. -All HD2, HD3 products better than -90dBc at -1dB below clipping point.

  10. -Includes a wideband 56 MHz wide spectrum analyzer mode.

  11. -10x faster interface

  12. -Optional RS-232 3.5mm to DB9 cable for external radio control.

  13. -Built-in TCXO


  1. -HF and VHF monitoring

  2. -External high resolution panoramic and spectrum displays

  3. -GMDSS networks

  4. -Internet of Things (IoT) remote access point

  5. -Geolocation of remote signals

  6. -Distributed radio and sensor systems

  7. -Remote signal surveillance

  8. -Ionospheric sounding
