ColibriDDC

Two receivers in a palm-sized case.

A compact HF receiver with direct down-conversion (DDC) on a 14-bit ADC: 0.1–55 MHz, and up to 800 MHz in undersampling mode. IQ recording up to 312 kHz wide, in a 125 × 65 × 26 mm case.

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.
