Microphone problem

Bought Logitech USB micro, I think the one recommended on this site . Volume, though  (as recorded in Audacity) is too low and far worse than my old, non-USB micro -Typhoon - which I doubt is a known brand.

 Tips?  This the third course I'm trying to follow. I don't mind not being able to fly unaided by a plane, but I would LOVE to stream.    Dennis
