Our local sheriff uses a couple different frequencies. I can listen to them individually with sdr sharp. Is there a way to set it up to scan a couple frequencies that are saved as favorites? Or some other way to scan them with another program?

If you use the "Frequency Manager" there's a tickbox on the end marked "S" - that's for "Scan"

Tick the box and hit the Scan button and it will scan through those frequencies for you.
