Your video quite nicely shows the affect of the gain control. I look forward to playing with this.
 
I have the dongle on order, along with an adapter. Should be here tomorrow... | 
	
 I'm glad the video helped you; it is an important concept when using the dongle with SDR#.
Adjusting the gain of the RTLSDR Scanner is a little different. You raise the gain until the noise floor starts to rise and then stop. More precisely, when it starts to rise you back it off a little.
Gain set too low:
 
Correct gain setting:
 
Gain set too high:
 
With the RSP1A and Airspy R2 you adjust the gain and other contols for max SNR.
Good luck with your adventure.
