ColibriDDC

Small receiver

for great experts

Description

A compact ColibriDDC receiver was designed to work on HF band 0.09 to 55 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.
