Test report by Adam AB4OJ/VA7OJ: ColibriNANO Report
This manual describes the hardware of the receiver and explains operation of ExpertSDR2 software.
ColibriNANO is an excellent platform to experiment with a Dual Diversity receive! (Two RX antennas with different polarization separated at least 1/2 wavelength with two synchronized receivers are required).
The ColibriNANO opens new horizons for HF band enthusiasts, deploying 14-bit ADC, which provides a ~110 dB BDR and up to 3 MHz sample rate. A 0.5 ppm local oscillator insures ColibriNANO frequency stability. Use ColibriNANO remote over IP, and enjoy copying weak signals with minimal industrial RF interference. The ColibriNANO supports ExpertSDR2 special version of software and compatible with popular SDR open source software such as HDSDR, SDRSharp via the ExtIO library.

ExpertSDR2 software was written to support amateur radio SDR transceivers manufactured by Expert Electronics. 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 and control of the preamplifier and LPF.
- Supported modes: LSB/USB/DSB/CW/AM/SAM/NFM/WFM
- IQ output via Virtual Audio Cable (VAC)
- Compatibility with any sound card installed on your PC for the audio output
- Synchronization with transceivers via CAT interface
- Special interface to control the CW Skimmer
- Minimum window resolution 860x466 pix
- Support of the FullHD and 4K monitors
- All new versions of the software provided at no additional cost

Remote operation with the ColibriNANO receiver
To control the ColibriNANO via Internet Expert Electronics created ExpertRemote system, based on the client-server configuration. This system allows you to place the receiver and server at the remote location with minimal natural and men-made interference and Internet connection. With ExpertRemote system you can enjoy reception of weak signals from your smartphone, tablet, notebook or PC.
Another feature of this system is that the receiver's software can be synchronized with transceivers and can be used as the panoramic adapter with high resolution.
Distant stations, rare (DX) stations or expeditions from now on will be more accessible for you with ExpertRemote system!
