Calculation to make on ezCol to measure dB increase over background

ezCol, the data collection part of ezRA suite (Easy Radio Astronomy, GitHub – tedcline/ezRA: Easy Radio Astronomy), looks like it measures voltage rather than power so dB calculation 20x not 1x.

Performance on my system should be around 1x over background, 1.5-2x on good day (if system completely optimised and hitting bright spot in Milky Way) but 0.75x would be OK for Milky Way.
