KrakenSDR

Descripción

KrakenSDR from KrakenRF is a five-channel coherent software-defined radio for authorised RF work. Use it to collect and compare signals from multiple antenna inputs, support direction-finding projects and analyse spectrum data in security research, education and approved field investigations.

Key features

• Five coherent-capable receivers: five RTL-SDR circuits share one local oscillator for coherent signal processing.
• Automatic synchronisation: built-in hardware and supplied Linux software manage coherence synchronisation and calibration.
• Open-source software: KrakenRF provides open-source DAQ, DSP and direction-finding software, plus a GNU Radio interface.
• Web interface: configure frequency, gain and other DAQ settings, while viewing live spectrum and direction-finding output.
• Mobile direction finding: KrakenRF provides an Android application for mapping, logging data and estimating transmitter location. Direction-finding software is also available for iOS.
• Bias tees: each SMA input provides 4.5 V for compatible powered RF accessories.
• Field-ready enclosure: the aluminium enclosure is designed for heat dissipation and phase stability.

Compatibility and setup

KrakenSDR processing software runs on a separate host, typically a Raspberry Pi 4, Raspberry Pi 5, similar single-board computer or PC. A 5 V, 2.4 A or higher USB-C power supply, USB-C data cable and a five-element antenna array are required. Antennas and host hardware are not included unless separately specified.
