.Main Window:
- Select *FT4* on the *Mode* menu.
- Double-click on *Erase* to clear both text windows.
.Wide Graph Settings:
- *Bins/Pixel* = 7, *Start* = 100 Hz, *N Avg* = 1
- Adjust the width of the Wide Graph window so that the upper
frequency limit is approximately 4000 Hz.
.Open a Wave File:
- Select *File | Open* and navigate to
+...\save\samples\FT4\000000_000002.wav+. The waterfall and Band
Activity window should look something like the following screen shots.
Most of the decoded messages use the *RTTY Roundup* message formats.

- 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.
- Now double-click on any of the the lines of decoded text in the Band
Activity window. Any line will show similar behavior, setting
Rx frequency to that of the selected message and leaving Tx frequency
unchanged. To change both Rx and Tx frequencies, hold *Ctrl* down
when double-clicking.
TIP: To avoid QRM from competing callers, it is frequently desirable
to answer a CQ on a different frequency from that of the CQing
station. The same is true when you tail-end another QSO. Choose a Tx
frequency that appears to be not in use. You might want to check the
box *Hold Tx Freq*.
TIP: Keyboard shortcuts *Shift+F11* and *Shift+F12* provide an easy
way to move your FT4 Tx frequency down or up in 90 Hz steps.
IMPORTANT: When finished with this Tutorial, don't forget to re-enter
your own callsign as *My Call* on the *Settings | General* tab.
