Features
Lab and research
Undersampling receives signals above the ADC range, and IQ recordings are kept for analysis. Several receivers can run at once.
A receive site with a quiet band
Put the receiver where the band is quiet, at a country house away from city noise. The remote ColibriDDC receives, your home transceiver transmits.
RBN nodes
Four independent slices and data over TCI have made ColibriDDC a popular receiver for RBN skimmer nodes.
Direct headphone output
A built-in 24-bit audio codec feeds headphones directly.
Use Cases
- 01
Contest Skimmer Station
Continuous automated monitoring and CW/digital skimmer decoding across multiple bands.
- 02
Remote Listening Post
Install at an electrically quiet rural location and listen from your city apartment.
- 03
SDR Panadapter
Direct integration with external transceivers as a high-performance second receiver.
ExpertSDR3, TCI and ERS
Free ExpertSDR3 with free updates. The open TCI protocol connects loggers, skimmers and digital-mode programs without virtual COM ports or audio cables; programs without TCI use the RadioSync bridge (CAT, OmniRig). Expert Remote System (ERS) is included: control from a browser or ExpertSDR3, directly or through the ExpertCloud service.
