Using my new Airspy/Spyverter combo with SDRSharp I'm picking up a "hum". If anyone can guide me on how to filter this out it would be greatly appreciated.

K5KNT, try using an USB extension cable.  There are several out there.  I use one with a repeater for my radio applications to get it away from the computer and its power supply.  If the hum is still present you could try grounding your computer case.
