A compact ColibriDDC receiver was designed to work on HF band 0.09 to 60 MHz, for better performance you can add the internal BPF-module (160-10M bands). With the help of external filters, ColibriDDC can effectively operate on frequencies up to 800 MHz. LAN interface allows you to use the receiver remotely via LAN cable and to connect several receivers to one PC at the same time, for various projects. Also, you can hook up the receiver with the RaspberryPi3 (with installed ExpertRS software) and use it from any place on the Planet, you just have to have a reliable internet connection.
Note! The basic version of the receiver doesn't include the BPF-module.

Specifications are subject to change without notice or obligation and specifications are only guaranteed within the amateur radio bands.
Optional BPF-kit board with HF octave band filters. BPF-kit could be installed inside the receiver's case, with a set of simple manipulation.
BPF-kit works either with RX1 or when RX1 and RX2 are on the same band. If RX1 and RX2 are on different bands, then ColibriDDC uses LPF. It's explained by the fact that RX1 and RX2 are software, not physical receivers.

Welcome to the new generation of SDR software – ExpertSDR3!
In 2021, we turned a new page in our history by launching the ExpertSDR3.
ExpertSDR3 software is being tested on the latest versions of Windows 10, Linux Ubuntu 22.04, and macOS 12 (with Intel CPU).
To report software bugs, please use this page.
ExpertSDR3 1.0.2 Beta
Server (Starter) for Expert Remote System, build 20221028
ExpertSDR3 minimal system requirements:
ExpertSDR3 1.0.5 Beta - 5th of May 2023
ExpertSDR3 1.0 Final - 25th of December 2023
During the year, we will publish minor releases of the program with bug fixes, without reference to specific dates.
