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

Opera Cake is an antenna switching add-on board for HackRF One that is configured with command-line software either manually, or for automated port switching based on frequency or time. It has two primary ports, each connected to any of eight secondary ports, and is optimized for use as a pair of 1×4 switches or as a single 1×8 switch. Its recommended frequency range is 1 MHz to 4 GHz.

The PortaPack H4M attaches to your HackRF and adds a touchscreen display, navigation controls, headphone jack, a real-time clock, and micro SD card slot.

Power though internal battery, USB power supply, or computer.

The PortaPack firmware runs on the fast ARM processors in your HackRF. No computer is necessary (except for reprogramming firmware).

Notes: The HackRF One is not included. If you don’t have one, you can purchase one here.

HackRF One is a Software-Defined Radio that enables fast and accurate transmission of radio signals. With excellent range and capability, it can receive and transmit signals from 1 MHz to 6 GHz. The HackRF One is an open-source platform that works as a USB peripheral. It can be programmed and managed as stand-alone device and system.

HackRF One acts like a sound card of computer. It processes Digital Signals to Radio waveforms allowing integration of large-scale communication networks. It is designed to test, develop, improvise and modify the contemporary Radio Frequency systems.

While we are constantly surrounded by radio waves and digital tech such as broadcasting stations, WiFi, bluetooth, smart phones, GPS and IT infrastructures, the HackRF One is a Software-Defined Radio that can interact with any of these technologies. The majority of wireless systems in the digital age could easily be transceived by HackRF One. The vision behind it is to bring an open source peripheral that could assist modern day engineers and researchers for improving next generation communication systems.

ANT500 is a telescopic antenna suitable for radio frequencies between 75 MHz and 1000 MHz. The 50 ohm antenna total length is 20 cm collapsed to 88 cm fully extended. It is the perfect first antenna for general purpose use with HackRF One.
