Small-size ColibriDDC receiver is intended to receive the signals in HF frequency band 0.09 to 55 MHz, and also with the help of external filters to receive frequencies up to 800 MHz and work together with PC. It was designed in accordance with the principle of direct digital signal sampling by high speed analog-digital converter. Such architecture allows to get rid off additional noise of analog cascades and makes the air sound natural and transparent. Local network interface allows to use the device remotely and also allows to connect simultaneously several receivers to one PC for solving various signal receipt tasks. ColibriDDC is a good low-cost receiver to review the technology of direct sampling which can be used in different spheres.

Note! The receiver doesn't contain band pass filters and can be overloaded by the strong signals from air.

Main capabilities 

  • ADC with sampling frequency 125 MHz and 14 bit resolution is used
  • Two independent receiving channels with sampling frequencies up to 312 kHz
  • Record air stations with the bandwidth to 312 kHz and the opportunity to reproduce it later
  • Opportunity to receive in Nyquist zones up to 800 MHz (necessary to set additional external filters)
  • Wide spectrum scope up to 60 MHz
  • 24 bit audio  DAC for decreasing signal delay
  • Connector for controlling external devices, 7 programmable transistor switches
  • Interface with PC  local network 100 Mbps
  • Low power consumption, 5V 0.64A
  • External reference generator input 10 MHz
  • Small dimensions W 64 x H 24 x L 112 mm
  • ExpertSDR2 receiver's software

Application field

  • Dual chanel HF receiver
  • Panadapter  to classical transceivers
  • Remote reception point for contests and other applications
  • Spectrum analyzer with wide spectrum scope up to 60 MHz
  • Work with external digital signal decoders (digital type connection programs, CW skimmer, etc.)

PC requirements

  • Processor Intel Core2Duo and higher
  • Video card supporting the technology of OpenGL 1.5 and higher and RAM 256 Mbyte and more
  • Local network connector 100 Mbps or 1 Gbps
  • OS Windows XP/7/8 x32 or x64, OS Linux Ubuntu x64


ExpertSDR2 program with adapted interface for the receiving mode is used together with the ColibriDDC receiver. At the present moment software works in the receiving mode and maintains two independent channels with the bands to 312 kHz. DSP library, developed by the company Expert Electronics, allowed to improve the receipt quality and to higher the software reliability. Two OS are supported: Windows 8 and Linux Ubuntu.
