How to change Radio Panel from slice A to Slice B

Hi John, the slice that is "active" will show in the panel. Assuming that you are using SmartSDR for Windows, click on the flag of the slice you want to be the active one. You can also click on the vertical line when you get the hand cursor icon. The active slice will have a yellow vertical line at the carrier frequency and the inactive slice will have a red line.

The mouse wheel will control the frequency of the active slice, so this is a really handy thing to know.
