KRAKENSDR-01

Software Defined Radio

KrakenRF Software Defined Radio (KrakenSDR) is a coherently operated, five-RX-channel radio based on the RTL-SDR, allowing radio direction finding and beamforming. KrakenSDR uses five custom RTL-SDR circuits consisting of R820T2 and RTL2832U chips. To achieve phase coherence, KrakenSDR drives all five RTL-SDR radios with a single clock source and contains internal calibration hardware to allow the phase relationship between channels to be measured precisely and corrected in software. Additionally, the overall design of KrakenSDR works to ensure phase stability, with care taken in heat management, driver configuration, power supply, and external interference mitigation.
