EU Orders, Software Updates, and Antenna-Array Spacing Information

If you had trouble placing an order from the EU and received errors about a missing CE certification, please give it another try. There appears to have been a misconfiguration in Crowd Supply's ordering system that incorrectly excluded EU backers for approximately five days. That misconfiguration has since been fixed. For clarification, KrakenSDR will have CE certification, making it legal to sell and use within the EU. This update also includes details about our software-development progress and about antenna-array spacing. Read the full update.

Manufacturing News, Beacon-Tracking Experiments, Antenna Details, and a FAQ Update

Thanks to everyone who's following along with this project. We've now sold well over half of the initial 1,000-unit batch we are planning to produce immediately following the campaign.

So please do order early if you want to get your KrakenSDR by the date currently shown on the campaign page! Meanwhile, here's an update on what's been keeping us busy. Read the full update.

Phase-coherent SDR opens the door to some very interesting applications, including radio direction finding, passive radar, and beam forming. Come have a look at our campaign page to learn more!
