.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 the Rx 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. All three lines will show the same 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.
|
||||
|
||||
NOTE: 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.
|
||||
|
||||
NOTE: Keyboard shortcuts *Shift+F11* and *Shift+F12* provide an easy
|
||||
way to move your Tx frequency down or up in 60 Hz steps.
|
||||
|
||||
NOTE: Further helpful tips on FT8 operating procedures are available
|
||||
{ft8_tips}. Thanks to ZL2IFB!
|
||||
|
||||
.FT8 DXpedition Mode:
|
||||
|
||||
This special operating mode enables DXpeditions to make FT8 QSOs at
|
||||
very high rates. Both stations must use _WSJT-X_ Version 1.9 or
|
||||
later. Detailed operating instructions for {ft8_DXped} are available
|
||||
online. Do not try to use DXpedition mode without reading these
|
||||
instructions carefully!
|
||||
|
||||
IMPORTANT: FT8 DXpedition mode is intended for use by rare-entity
|
||||
DXpeditions and other unusual circumstances in which sustained QSO
|
||||
rates well above 100/hour are expected. Do not use the multi-signal
|
||||
capability unless you satisfy this requirement, and do not use
|
||||
DXpedition Mode in the conventional FT8 sub-bands. If you are
|
||||
contemplating operation as Fox using DXpedition Mode, find a suitable
|
||||
dial frequency consistent with regional band plans and publicize it
|
||||
for the operators you hope to work. Remember that on-the-air signal
|
||||
frequencies will be higher than the dial frequency by up to 4 kHz.
|
||||
|
||||
IMPORTANT: When finished with this Tutorial, don't forget to re-enter
|
||||
your own callsign as *My Call* on the *Settings | General* tab.
