2. Change "Appendix x" section headings to useful descriptions. 3. Add KB1ZMX and W4TI to the WSJT-X "About" screen and Acknowledgments in the User's Guide. (Hope I didn't forget anyone -- please advise if I did!) 4. A few more minor tweaks to User's Guide git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@3672 ab8295b8-cf94-4d9e-aec4-7959e3be5d79

.Open a Wave File:
|
|
|
|
- Select *File | Open* and navigate to
|
|
+...\save\samples\130418_1742.wav+ under the _WSJT-X_ installation
|
|
directory. When the file opens you should see something similar to
|
|
the to the following screen shot:

.Decoding Overview
|
|
|
|
Notice the [green]*GREEN* and [red]*RED* markers on the waterfall
|
|
frequency scale. Decoding takes place at the end of a receive
|
|
sequence and is organized in two stages. The first decodes take place
|
|
at the selected Rx frequency, indicated by the [green]*GREEN* marker
|
|
on the waterfall scale. Results appear in both the left (*Band
|
|
Activity*) and right (*Rx Frequency*) text windows on the main
|
|
screen. The program then finds and decodes all signals in the selected
|
|
mode(s) over the displayed frequency range. The [red]*RED* marker
|
|
indicates your Tx frequency.
|
|
|
|
Seven JT9 signals are present in the example file, all decodable.
|
|
When this file was recorded KF4RWA was finishing a QSO with K1JT.
|
|
Since the green marker was placed at his audio frequency, 1224 Hz, his
|
|
message ``K1JT KF4RWA 73'' is decoded first and appears in the *Rx
|
|
Frequency* window. The *Band Activity* window shows this message plus
|
|
all decodes at other frequencies. Lines containing CQ are highlighted
|
|
in [green]*GREEN*, and lines with *My Call* (in this case K1JT) in
|
|
[red]*RED*.
|
|
|
|
TIP: For this step and the next, you may want to pretend you are K1JT
|
|
by entering that callsign temporarily as *My Call* on the <<X11,*Setup
|
|
| Configuration*>> screen. Your results should then be identical to
|
|
those shown in the screen shot above.

|
.Decoding Controls
|
|
|
|
To gain some feeling for controls frequently used when making QSOs,
|
|
try clicking with the mouse on the decoded text lines and on the
|
|
waterfall spectral display. You should be able to confirm the
|
|
following behavior:
|
|
|
|
- Double-click on either of the decoded lines highlighted in
|
|
green. This action produces the following results:
|
|
|
|
** Callsign and locator of a station calling CQ are copied to the *DX
|
|
Call* and *DX Grid* entry fields.
|
|
|
|
** Messages are generated for a standard minimal QSO.
|
|
|
|
** The *Tx even* box is checked or cleared appropriately, so that you
|
|
will transmit in the proper (odd or even) minutes.
|
|
|
|
** The Rx and Tx frequency markers are moved to the frequency of the
|
|
CQing station.
|
|
|
|
** The *Gen Msg* (``generated message'') radio button at bottom right
|
|
of the main window is selected.
|
|
|
|
** If you had checked *Double-click on call sets Tx Enable* on the
|
|
*Setup* menu, *Enable Tx* would be activated and a transmission would
|
|
start automatically at the proper time.
|
|
|
|
- Double-click on the decoded message ``K1JT N5KDV EM41'',
|
|
highlighted in [red]*RED*. Results will be similar to those in the
|
|
previous step, except the Tx frequency ([red]*RED* marker) is not
|
|
moved. Such messages are usually in response to your own CQ, or from
|
|
a tail-ender, and you probably want your Tx frequency to stay where it
|
|
was.
|
|
|
|
- By holding down the *Ctrl* key when double-clicking on a decoded
|
|
line you can cause both Tx and Rx frequencies to be moved. This
|
|
behavior can also be forced by checking *Lock Tx=Rx*.
|
|
|
|
- Double-click on the message from KF4RWA in either window. He is
|
|
sending ``73'' to K1JT, signifying that the QSO is over. Most likely
|
|
you want to send 73 to him, so the message ``KF4RWA K1JT 73'' is
|
|
automatically generated and selected for your next transmission.
|
|
(Alternatively, you might choose to send a free text message or to
|
|
call CQ again.)
|
|
|
|
- Click somewhere on the waterfall to set Rx frequency ([green]*GREEN*
|
|
marker).
|
|
|
|
- Ctrl-click on the waterfall to set both Rx and Tx frequencies.
|
|
|
|
- Double-click on a signal in the waterfall to set Rx frequency and
|
|
start a narrow-band decode there. Decoded text will appear in the
|
|
right window only.
|
|
|
|
- Ctrl-double-click on a signal to set both Rx and Tx frequencies and
|
|
decode at the new frequency.
|
|
|
|
- Click *Erase* to clear the right window.
|
|
|
|
- Double-click *Erase* to clear both text windows.
