Description

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

Specifications are subject to change without notice or obligation and specifications are only guaranteed within the amateur radio bands.

BPF-KIT

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.

160M: 1.73-2.6 MHz
80M: 2.6-4.3 MHz
60M: 4.3-6.5 MHz
40M: 6.5-7.9 MHz
30M: 7.9-13 MHz
20M: 13-15.9 MHz
17-15M: 15.9-21.0 MHz
12-10M: 21.0-30 MHz
ATT -20 dB
Preamp +10 dB

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.
