Hi,

May I ask what is the purpose of #4 & #7 noise calibration circuit?

Thanks in advance for explaining.

Best - Rick

The KrakenSDR needs a noise source to be able to correlate and calibrate each channel. So in calibration mode the noise source is turned on, and the samples and phases of all the tuners are aligned with the first tuner via correlation. A wideband noise source makes correlation possible.
