.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.
|
|
|
|
- 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.
|
|
|
|
IMPORTANT: When finished with this Tutorial, don't forget to re-enter
|
|
your own callsign as *My Call* on the *Settings | General* tab.
