-The position of the blue marker on the waterfall scale is
-set by the spinner control *JT65 nnnn JT9*, where nnnn is an audio
-frequency in Hz. In *JT9+JT65* mode the program will automatically
-decode JT9 signals only above this frequency. JT65 signals will be
-decoded over the full displayed frequency range.
-
-JT9 signals appear in the *Cumulative* spectrum as nearly rectangular
-shapes about 16 Hz wide.  They have no clearly visible sync tone like
-the one at the low-frequency edge of all JT65 signals.  By convention
-the nominal frequency of both JT9 and JT65 signals is taken to be that
-of the lowest tone, at the left edge of its spectrum.
-
-This sample file contains 17 decodable signals — nine in JT65 mode
-(flagged with the character # in the decoded text windows), and eight
-in JT9 mode (flagged with @).  On multi-core computers the decoders
-for JT9 and JT65 modes run simultaneously, so their results will be
-interspersed.  The *Band Activity* window contains all decodes (you
-might need to scroll back in the window to see some of them).  A
-signal at the frequency specified by the green marker is given
-decoding priority, and its message is displayed also in the *Rx
-Frequency* window.

-Taking full advantage of the wide-band, dual-mode capability of

-data were recorded with a much narrower Rx bandwidth, roughly 200 to
-2400 Hz. If you have no Rx filter wider than about 2.7 kHz, you will
-be using data like this. For best viewing, adjust *Bins/Pixel* and the
-width of the Wide Graph so that only the active part of the spectrum
-shows, say 200 to 2400 Hz.  Re-open the example file after any change of
-*Bins/Pixel* or Wide Graph width, to refresh the waterfall.

-Now is a good time to experiment with the *Start* control and the
-sliders controlling gain and zero-point of the waterfall and spectrum
-plots.  *Start* determines the frequency displayed at the left side of
-the waterfall scale.  Sliders set the baseline level and gain for the
-waterfall and the several types of spectra.  Good starting values
-should be close to mid-scale.  You might want to uncheck *Flatten*
-when adjusting the sliders.  Re-open the wave file after each change,
-to see the new results.
