One of the great features on Icom’s flagship IC-7851 is the ability to have two scopes on the display at the same time. Each scope will display the information for the frequency, mode and antenna that is active on each receiver. The scope can be displayed vertically (side-by-side) or horizontally (top and bottom), depending on your preference. The dual scopes will also display on the high resolution monitor you have connected to the IC-7851.
An additional cool and very useful feature of the IC-7851 is the ability to connect a mouse to the radio and click on a signal that is displayed on either scope. This makes it much easier to quickly tune to the signal you are seeing on the scope.
Here is a video demonstrating this great dual scope feature.
