RF ADC 14-bit 122.88Msps

Direct Sampling SDR-based receiver


The ColibriNANO opens new horizons for HF band enthusiasts, thanks to its 14-bit ADC, which provides a ~110 dB BDR and up to 3 MHz sample rate. A 0.5 ppm local oscillator gives the ColibriNANO a great frequency stability. Using the ColibriNANO remotely, in some rural area will give you the lowest air noise you've ever seen while won't rob you from any comfort or functionality. The ColibriNANO operated by our own ExpertSDR2 software and compatible with popular HAM software such as HDSDR, SDRSharp via the ExtIO library.


Typical Applications 

  • Direct connection with your laptop
  • Remote operation
  • Remote connection with a local transceiver
  • Spectrum analyzer

Remote operation with the ColibriNANO receiver

To control the ColibriNANO via Internet we created the ExpertRemote system, based on the client-server connection. This system allows you to place the receiver and server in the remote location with low air noise and Internet connection. This might be some remote village or place with no electrical interference and 3G/4G Internet (or any other connection type). Using the ExpertRemote system you can enjoy clear air from your phone, tablet, notebook or PC. Even simple antennas, placed in a "quiet" place, allows you to listen to the far stations with low level.
Another feature of this system is that the receiver's software can be synchronized with transceivers and be used as the panorama adapter with high resolution. Use the transceiver to transmit signals, receive on your remotely located receiver via the ExpertRemote system. 

Distant stations, rare (DX) stations or expeditions from now on will be a reality for you with our ExpertRemote system!

Library for operation with ColibriNANO receiver

Library compiled for x32, x64 and x32 for WindowsXP (not tested) platforms. Library folder contains all compiled libraries and binary examples for x32 and x64 platform, not x32 Windows XP. In the example_src folder you may find the example project created with Qt 5.10 libs and compiled in Visual Studio 2017.

ExtIO library to work with third-party software

zip icon ExtIO_ColibriNANO

We've made additional tests of the ColibriNANO and found out, that sometimes ExpertSDR2 detects the receiver incorrectly if there are other devices with FTDI chip connected. To make the ExpertSDR2 identify the receiver correctly we added a special descriptor. Please make a certain procedure described in the attached document only once, if you have problems with ExpertSDR2 connecting to the ColibriNANO:

Set the serial number

Ready to use setups, just download, and launch:

zip icon HDSDR_2.7.6_ExtIO_ColibriNANO
zip icon SDR#_v1005_ExtIO_ColibriNANO

The ExtIO library was created using Qt 4.8.7.
The HDSDR software was downloaded from the official website

The SDR# software version 1005.

To use the ExpertSDR2 software, please install the Visual Studio Redistributable 2017 either from the ExpertSDR2 installer or from the official Microsoft website:

If your Windows will not automatically download the USB driver, to use the ColibriNANO, download drivers from one of the links below and manually assign them to the undetected device in the Device Manager menu. Dismiss Windows warning regarding unsigned software and proceed with the installation.

ExpertSDR2 works on macOS Mojave.

Only for macOS users:
Recently we've been informed that some macOS devices might have an issue with detecting the ColibriNANO, the issue is in the FTDI drivers. Here is the link to the official FTDI doc, which describes how to fix that, follow items 4.2 and then 3.3: FTDI Drivers Installation guide for MAC OS X.
