A waterfall shows a spectrum over time: one axis represents frequency, the other time. Colour represents relative signal level.

A waterfall stacks successive measurements over time.

The spectrum above the waterfall is usually an instantaneous or averaged view.

Try tuning, filter bandwidth and AM, FM, USB, LSB or CW on a simulated waterfall.

Louder audio or a brighter waterfall does not automatically mean a better signal-to-noise ratio.

The 2.3-inch colour display presents frequencies, callsigns and a waterfall view for spotting activity within the monitored band.

Is the waterfall updating?

A computer provides the spectrum display, waterfall and demodulation.

If the waterfall shows activity but you hear nothing, avoid changing every radio parameter at once.

Waterfall display is a separately paid upgrade, not a guaranteed part of EDNP.

Select the signal in the waterfall and fine-tune it.
