These documentation source files are not the one true version, just a copy for testing purposes. DO NOT EDIT THESE FILES. To use this on Windows you will need a working asciidoc installation and the path to it must be included in your CMAKE_PREFIX_PATH (probably via a local CMake tool chain file). At the time of writing the official asciidoc package does not work on Windows. The latest development master does however work, it can be downloaded as a snapshot ZIP archive from here: https://github.com/asciidoc/asciidoc/archive/master.zip git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@5316 ab8295b8-cf94-4d9e-aec4-7959e3be5d79

The following controls appear at the bottom of the Wide Graph window.
|
|
With the exception of *JT65 nnnn JT9*, they affect only the graphical
|
|
displays — they 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 for wide-band decoding of
|
|
JT65 and JT9 signals in *JT9+JT65* mode. The decoder looks for JT65
|
|
signals below the specified frequency and JT9 signals above it.
|
|
|
|
- *Start nnn Hz* sets the low-frequency starting point of the
|
|
waterfall frequency scale.
|
|
|
|
- *N Avg* is the number of successive FFTs to be averaged before
|
|
updating the spectral 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.
|
|
|
|
- *Zero* and *Gain* control the scaling and reference level for
|
|
waterfall colors. Values around 0 for both parameters are usually
|
|
about right, depending on the input signal level and your own
|
|
preferences.
|
|
|
|
- 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 create a
|
|
user-defined palette.
|
|
|
|
- Check *Flatten* if you want _WSJT-X_ to compensate for a sloping or
|
|
uneven response across the received passband.
|
|
|
|
- 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.
