for great experts
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.
Main features and capabilities of the receiver
RX path based on DDC (Direct Down-Conversion) architecture
ExpertRemote system provides full remote control of the receiver
2 software receivers (each up to 312 kHz) + SubRX for each of them (4 slices total) + independent wideband Bandscope up to 62.5 MHz
ExtCTRL connector to control external devices with 7 powerful keys with open collector
100 Mbps Ethernet LAN interface provides fast and reliable connection to PC
TCI interface for seamless connection with third-party software like SDC (with its own Skimmer), LogHX, SWISSLOG and RUMlog, more are coming
Record IQ channel with the bandwidth up to 312 kHz
Receiving in undersampling mode up to 800 MHz (requires external BPF)
High-quality 24-bit audio–DAC installed for the smallest signal delays
Low power consumption, 5V 0.64A
External reference generator input 10 MHz
Small size W 65 x H 26 x L 125 mm
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.
