smaller files, by section and sub-section. Also extensive editing up through section 7. Sections 6.2, 8, and beyond definitely need work. Other polishing is also desirable, and maybe also some additions and/or changes. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@3656 ab8295b8-cf94-4d9e-aec4-7959e3be5d79

The following controls appear at the bottom of the Wide Graph window:
|
|
|
|
image::images/wide-graph-controls.png[align="left",alt="Wide Graph Controls"]
|
|
|
|
* *FFT Bins/Pixel* controls the displayed frequency resolution. Set
|
|
to 1 for the highest possible resolution, or to higher values to
|
|
compress the spectral display. Normal operation with a convenient
|
|
window size works well at 2 to 8 bins per pixel.
|
|
|
|
* *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.
|
|
|
|
* *Gain* and *Zero* 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.
|
|
|
|
* *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 nnnn Hz and JT9 signals above that frequency.
|
|
|
|
* *Current / Cumulative* controls the graphical display 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 current Rx sequence.
|
|
|
|
* With the exception of *JT65 nnnn JT9*, controls on the Wide Graph
|
|
window affect only the graphical displays — they have no effect
|
|
on the decoding process.
