There have been changes to the way we are able to hear the Okanogan County Sheriffs office (Washington)over the air since an upgrade. Sometimes we hear everything on car to car 155.715 and other main channels, but they can now block the same channel intermittently so only dispatch and other cars can hear. They called it "green". How do I update? The frequency itself hasn't changed. How are they doing it?
