Five channel RTL-SDR correlation testing issues. One, Log10 warrning due to no data being pushed through, even though an internal noise source set to constantly on. Second issue, the Acer mini-pc is under powered, even with a 2.4GHz processor with four cores. The correlation test, does show five RTL-SDR, KrakenSDR channels can correlate. -

Testing the interferometer with GNU Radio, out of tree (OOT), custom block build. Both two channel, KrakenSDR receivers are coherent and are in phase array. -

Two, NooElec - SawBird H+1 LNAs along with two Wideband pass Preamps at 0.1 - 4 GHz. The bottom RTL-SDR, is the five channel KrakenSDR. To the left is a AGO 1420 MHz, band pass filter (BFP) -

This is my work in progress gallery. I'm experimenting and learning how to produce beautiful images, as so many I've see here on Stargazers Lounge.
