KerberosSDR - 4x Coherent RTL-SDR

KerberosSDR is out of stock and end of life. Learn more about the upgraded KrakenSDR produced by KrakenRF. A Coherent RTL-SDR with 4x Channels. For direction finding, passive radar, beam forming, or just as four RTL-SDRs!   We have developed a low-cost, 4-tuner phase-coherent RTL-SDR software defined radio. The applications could include radio direction finding, passive radar, beam forming or to simply use as four convenient RTL-SDR dongles. We have developed custom software that shows off direction finding and passive radar capabilities. The base DSP and phase synchronization code could be adapted to any coherent application that you have in mind.  The RTL-SDR software defined radio phenomenon has changed the world by unlocking low cost access to the radio spectrum. Whilst RTL-SDR is now a relatively mature commodity item that almost everyone whose tinkered with electronics has played with, there is still so much more potential to be unlocked. A phase coherent RTL-SDR can be
