Waterfall Feature Operation Manual
1. Introduction
The Waterfall Feature is available for the USDS100 scanner. It covers a user-selectable
span or band of the radio spectrum to show you graphically the radio transmissions that
are present. The Waterfall feature quickly shows you how active a span or band of the
spectrum is. When you see a transmission displayed, you can navigate to it to listen to
it.
Since all transmissions occurring in the selected span will display at the same time, you'll
be able to see possible relationships between transmissions. For example, you might
see simultaneous repeater transmissions on multiple frequencies or find a repeater input
frequency associated with the repeater output frequency. The strength of signals will
provide clues about the nature of the transmissions or how far or near the transmitters
are. Alternatively, they will tell you the relative strengths of transmitters.
observations will enable you to gain a quick understanding of unfamiliar radio systems or
of a new location.
