=== Documentation Conventions
We include screen shots that illustrate many of the settings and
features of _WSJT-X_. Keep in mind that _WSJT-X_ is a multi-platform
application: the detailed appearance of windows and user controls may
be significantly different in Windows, Linux, or macOS environments.
The underlying functionality is the same on all operating systems,
however. Where desirable we call special attention to important
platform differences.
In this manual the following icons call attention to particular types
of information:

upper portion of the window shows a waterfall plot of the frequency spectrum (a spectrogram) and
a line plot of the current or average spectrum. Controls at the bottom of the window are used to
set up the displayed audio frequency range, color palette, and scaling of the spectrum displays.
A control on the bottom right of the Wide Graph (displayed as *Spec nn%*) allows the user to control
the vertical fraction of the window that is occupied by the spectrum line plot.
A control on the bottom right of the Wide Graph (displayed as *Spec nn%*) lets you control
the vertical fraction of the window occupied by the spectrum line plot.
It is important to set appropriate lower and upper
audio frequency limits for the Wide Graph because these limits define the FT8 decoder's search window.
For this tutorial, the limits will be set to cover 100-3300 Hz:
