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.

The ExpertSDR2 minimal system requirements:
The ExpertSDR2 software supports Windows 7-10 32/64 bit, Linux (Ubuntu/Kubuntu 18.04 x64), and macOS 10.14 Mojave and higher.
Compatible HAM software
Expert Electronics company developed the ExpertSDR2 software to control HAM radio equipment of its own design. Software version for the ColibriNANO allows you to harness all the potential of the receiver: remote operation, synchronization with the transceiver, IQ channel bandwidth up to 3 MHz, control of the preamplifier and LPF.

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!

Three ways to work with the ColibriNANO, by Werner Schnorrenberg DC4KU (on English and German):
- connect it via USB with the Notebook/PC (Standard)
- connect it via Raspberry and LAN/WLAN with the Notebook or Smartphone/Tablet in your home network
- connect it via Raspberry to the internet (www)
Warning! Software is device-specific! Don't mix software with unsuitable hardware, it may lead to issues that are not covered by warranty!
Library compiled for x32, x64, and x32 for WindowsXP (not tested) platforms. Library folder contains all compiled libraries and binary examples for the x32 and x64 platforms, not the 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
Ready to use setups, just download, and launch:
The ExtIO library was created using Qt 4.8.7.
The SDR# software version 1005.
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.
