Setting up the Linrad waterfall with high sensitivity for weak signals

Leif, the programmer of Linrad has uploaded a video on YouTube showing how to set up it’s waterfall for very high sensitivity reception of extremely weak signals. Linrad is an SDR GUI receiver software with a tough learning curve, but very advanced features. In the tutorial Leif uses an RTL-SDR dongle to receive a weak beacon at 144.412 MHz. He shows how to adjust the Linrad settings to produce a waterfall and FFT spectrum that it optimized for visualizing and tuning to very weak signals such as distant beacons.
