KrakenSDR is a software-defined, coherently operated, five-RX-channel radio based on RTL-SDR. A coherent radio allows for very interesting applications, such as radio direction finding, and beamforming.

Features & Specifications

• Five-channel, coherent-capable RTL-SDR, all clocked to a single local oscillator
• Built-in automatic coherence synchronization hardware
• Automatic coherence synchronization and management via provided Linux software
• 24 MHz to 1766 MHz tuning Range (standard R820T2 RTL-SDR range, and possibly higher with hacked drivers)
• 4.5 V bias tee on each port
• Core DAQ and DSP software is open source and designed to run on a Raspberry Pi 4
• Direction-finding software for Android (free for non-commercial use)

The KrakenSDR replaces the KerberosSDR product.

Note: KrakenSDR does not include the require USB-C power supply and data cable, and does not include application specific antennas.

A set of five magnetic whip antennas that can be used with the KrakenSDR for direction finding. The magnets are strong enough to secure the antennas to the roof of a moving car, and the cables are length matched with a VNA to ensure as little phase distortion as possible.

Includes:

• 5x SMA whip antenna usable from 100 MHz to 1 GHz.
• 5x Magnetic Mount Bases
• 5x SMA Tees, for mounting the whip antennas onto the base
• 5x 2 meter long length matched SMA to SMA cables
