The following controls appear at the bottom of the Wide Graph window.
|
|
Decoding occurs only in the displayed frequency range; otherwise, with
|
|
the exceptions of *Start NNN Hz* and of *JT65 nnnn JT9* when operating
|
|
in JT9+JT65 mode, controls on the Wide Graph window have no effect on
|
|
the decoding process.
|
|

|
|
|
|
- *Bins/Pixel* controls the displayed frequency resolution. Set this
|
|
value to 1 for the highest possible resolution, or to higher numbers
|
|
to compress the spectral display. Normal operation with a convenient
|
|
window size works well at 2 to 8 bins per pixel.
|
|
|
|
- *JT65 nnnn JT9* sets the dividing point (blue marker) for wide-band
|
|
decoding of JT65 and JT9 signals in *JT9+JT65* mode. The decoder
|
|
looks for JT65 signals everywhere, but JT9 signals only above this
|
|
frequency. This setting is stored separately for each band.
|
|
|
|
- *Start nnn Hz* sets the low-frequency starting point of the
|
|
waterfall frequency scale.
|
|
|
|
- *N Avg* is the number of successive spectra to be averaged before
|
|
updating the display. Values around 5 are suitable for normal JT9 and
|
|
JT65 operation. Adjust *N Avg* to make the waterfall move faster or
|
|
slower, as desired.
|
|
|
|
- A dropdown list below the *Palette* label lets you select from a
|
|
wide range of waterfall color palettes.
|
|
|
|
- Click *Adjust* to activate a window that allows you to import or export a
|
|
user-defined palette.
|
|
|
|
- Check *Flatten* if you want _WSJT-X_ to compensate for a sloping or
|
|
uneven response across the received passband. For this feature to
|
|
work properly, you should restrict the range of displayed frequencies
|
|
so that only the active part of the spectrum is shown.
|
|
|
|
- Select *Current* or *Cumulative* for the spectrum displayed in the
|
|
bottom one-third of the Wide Graph window. *Current* is the average
|
|
spectrum over the most recent *N Avg* FFT calculations. *Cumulative*
|
|
is the average spectrum since the start of the present UTC minute.
|
|
*Linear Avg* is useful in JT4 mode, especially when short-form
|
|
messages are used.
|
|
|
|
- Four sliders control reference levels and scaling for waterfall
|
|
colors and the spectrum plot. Values around midscale are usually
|
|
about right, depending on the input signal level, the chosen palette,
|
|
and your own preferences. Hover the mouse over a control to display a
|
|
tip reminding you of its function.
|
|
|
|
- The *Spec nn%* control is used to set the fractional height of
|
|
the spectrum plotted below the waterfall.
|
|
|
|
- *Smooth* is active only when *Linear Average* is selected.
|
|
Smoothing the displayed spectrum over more than one bin can enhance
|
|
your ability to detect weak EME signals with Doppler spread more than
|
|
a few Hz.

[[CONTROLS_FAST]]
|
|
=== Fast Graph
|
|
|
|
The waterfall palette used for the Fast Graph is the same as the one
|
|
selected on the Wide Graph. Three sliders at the bottom of the Fast
|
|
Graph window can be used to optimize gain and zero-offset for the
|
|
displayed information. Hover the mouse over a control to display a
|
|
tip reminding you of its function. Clicking the *Auto Level* button
|
|
produces reasonable settings as a starting point.

[[CONTROLS_ECHO]]
|
|
=== Echo Graph
|
|
|
|
The following controls appear at the bottom of the Echo Graph:
|
|
|
|
image::echo-graph-controls.png[align="center",alt="EchoGraph Controls"]
|
|
|
|
- *Bins/Pixel* controls the displayed frequency resolution. Set this
|
|
value to 1 for the highest possible resolution, or to higher numbers
|
|
to compress the spectral display.
|
|
|
|
- *Gain* and *Zero* sliders control scaling and offset of plotted
|
|
spectra.
|
|
|
|
- *Smooth* values greater than 0 apply running averages to the plotted
|
|
spectra, thereby smoothing the curves over multiple bins.
|
|
|
|
- Label *N* shows the number of echo pulses averaged.
|
|
|
|
- Click the *Colors* button to cycle through six possible choices of
|
|
color and line width for the plots.
|
|
|
|
[[CONTROLS_MISCELLANEOUS]]
|
|
=== Miscellaneous
|
|
|
|
Most windows can be resized as desired. If you are short of screen
|
|
space you can make the Main Window and Wide Graph smaller by hiding
|
|
some controls and labels. To enable this feature uncheck the box
|
|
labeled *Controls* at top left of the *Wide Graph* window, or the box
|
|
*Menus* to the right of the *Tune* button on the Main Window.
