KrakenSDR

Description

KrakenSDR utilizes UsB-C ports for Power and Data.
The KrakenSDR provides peep holes for several status LED indicators.
PWR LED: The white PWR LED to the right of the two UsB-C ports indicates that the KrakenSDR isreceiving DC power from the POWER USB-C port.
NOISE LED: When illuminated the white NOisE LED to the right of the PWR LED indicates that thenoise source on the KrakenSDR is active. This LED may flash briefly every few minutes when runningthe software when calibration monitoring/auto recalibration is turned on.
CHANNEL LEDS: There are five blue CHANNEL LEDs next to each of the SMA ports. When illuminatedthese LEDs indicate that this channels tuner has been enumerated by the computing device. Pleasenote that these LEDs do not provide status regarding the channel connection to the DsP software.

KrakenSDR Additional Hardware Requirements

KrakenSDR requires additional hardware listed below:

• Raspberry Pi 4/5, or similarly specified Linux single board computer, or a Linux PC
• A 5V 2.4A+ capable UsB-Cpower supply
• A USB-A to USB-C USB data cable
• Five phase/length matched antennas and cables.

KrakenRF sells the KrakenTenna set, which is a set of five length matched antennas and cables. lf youare using your own antennas, you must ensure that the antenna coax cables are at least all exactlythe same length, to at least within 0.5cm.

Key Use Cases

KrakenSDR’s main use case is for Radio Direction Finding (RDF). With RDF, a device like the KrakenSDRis used to determine a bearing towards a transmitter. These bearings can be plotted on a map, andthe location of the transmitter can be triangulated by taking multiple readings at different locations.
KrakenSDR can also be used a receive only software defined radio with five independent channels.

Typical Direction Finding Use Case Block Diagram

In a typical use case scenario for direction finding, you will have the antenna array mounted on theroof of a vehicle, with the KrakenSDR connected to a computing device like a Raspberry Pi 4 or 5. TheRaspberry 4/5 will communicate with the KrakenSDR mobile app via a mobile WiFi hotspot.
