-.Main Window:
- Select *FT8* on the *Mode* menu.
- Set Tx and Rx frequencies to 1200 Hz.
- Double-click on *Erase* to clear both text windows.
-
-.Wide Graph Settings:
-
- *Bins/Pixel* = 4, *Start* = 200 Hz, *N Avg* = 2
- Adjust the width of the Wide Graph window so that the upper
-frequency limit is approximately 2600 Hz.
-
-.Open a Wave File:
-
- Select *File | Open* and navigate to
-+...\save\samples\FT8\170709_135615.wav+.  The waterfall and decoded
-text window should look something like the following screen shots:

-
- Click with the mouse anywhere on the waterfall display. The green Rx
-frequency marker will jump to your selected frequency, and the Rx
-frequency control on the main window will be updated accordingly.
-
- Do the same thing with the Shift key held down.  Now the red Tx
-frequency marker and its associated control on the main window will
-follow your frequency selections.
-
- Do the same thing with the Ctrl key held down.  Now the both colored 
-markers and both spinner controls will follow your selections.
-
- Double-clicking at any frequency on the waterfall does all the
-things just described and also invokes the decoder in a small range
-around that frequency.  To decode a particular signal, double-click
-near the left edge of its waterfall trace.
-
- Now double-click on any of the the lines of decoded text in the main
-window.  Unless you have *My Call* set to K1JT or KY7M on the
-*Settings -> General* tab, all three lines will show the same
-behavior, setting both RxFreq and TxFreq to the frequency of the
-selected message.  However, if MyCall is set to K1JT then clicking on
-a message directed to K1JT will move only the Rx frequency setting.
-This behavior is desirable so that you will not inadvertently change
-your Tx frequency to that of a tail-ender who called you somewhere
-else in the FT8 subband.
-
-NOTE: The FT8 decoder can often copy several overlapping signals at
-nearly the same frequency.  However, in crowded band conditions you
-will often find it advantageous to move off the frequency of the
-station you are calling.  Keyboard shortcuts *Shift+F11* and
-*Shift+F12* provide an easy way to move your Tx frequency in 60 Hz
-steps.
-
-NOTE: Further helpful tips on FT8 operating procedures are available
-{ft8_tips}.  Thanks to ZL2IFB!
-
-IMPORTANT: When finished with this Tutorial, don't forget to re-enter
-your own callsign as *My Call* on the *Settings | General* tab.
