Welcome to KrakenRF

Updated: Jul 5, 2023

Welcome to our new website for KrakenRF. On this blog we will be posting all our updates relating to KrakenSDR, our software and any upcoming products that we are working on.

We want to thank all the people who backed KrakenSDR during the Crowd Funding campaign on Crowd Supply. We had multiple delays due to the pandemic and the subsequent supply chain crisis but now the KrakenSDR is here! We are still a bit constrained in manufacturing by the supply chain crisis but we are working hard on accelerating our production batches to meet demand.

A brief run down on KrakenSDR history:

KrakenSDR is the next iteration of the KerberosSDR, which is our previously 4-channel coherent RTL-SDR radio that we successfully Crowd Funded back in 2018. While KerberosSDR was a successful product, we wanted to improve on it, making it more rugged and suitable for remote deployments. At the same time we wanted to spend more time on the software, moving from code that was considered as 'demo software' for developers to get started with, to something more production ready and made for radio direction finding end users.

Compared to KerberosSDR the KrakenSDR improves many things:

  • Automatic calibration hardware. It is no longer necessary to manually disconnect antennas during calibration. It all happens automatically when you change frequency. This will allow for KrakenSDR stations to be remotely operated.

  • Five channels. KrakenSDR has five channels instead of four, which greatly improves-direction finding accuracy.

  • Low-noise design. KrakenSDR has a cleaner spectrum with much less internal noise than KerberosSDR.

  • USB Type-C ports and rugged, CNC-milled enclosure. KrakenSDR is built for high reliability in the field.

  • Interface with external devices. Bias tees on all ports allow for LNAs and other devices to be powered easily.

  • Improved DAQ, DSP, and GUI software. Built on the foundation of the KerberosSDR software, the KrakenSDR software adds auto-calibration, tracking of intermittent signals, greater stability, arbitrary processing-block sizes, and a new web-based GUI.

  • Software upgrades. Improvements to existing companion software and plans for new companion software.

  • Custom Android app Custom Android app that can automatically determine the location of a transmitter and provide automatic turn-by-turn navigation to the transmitter location.

This was our first KrakenSDR prototype:

We moved on to this version:

Before finally settling with this version:

On the final version we decided to incorporate a cooling fan, to ensure the KrakenSDR would work well even in extremely hot and stuffy environments like attic spaces.
