Thanks to W9MDB for this patch, which also removes the option *Double-click on call sets Tx Enable*. Please test and report any perceived issues! git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@8462 ab8295b8-cf94-4d9e-aec4-7959e3be5d79

For this step and the next, you may want to pretend you are K1JT
|
|
by entering that callsign temporarily as *My Call* on the
|
|
*Settings | General* tab. Your results should then be identical to
|
|
those shown in the screen shot below.
|
|
|
|
.Open a Wave File:
|
|
|
|
- Select *File | Open* and select the file
|
|
+...\save\samples\JT9\130418_1742.wav+. When the file opens you should
|
|
see something similar to the following screen shot:

.Decoding Overview
|
|
|
|
Decoding takes place at the end of a receive sequence and proceeds in
|
|
two steps. The first decode is done at the selected Rx frequency,
|
|
indicated by the U-shaped green marker on the waterfall frequency
|
|
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 over the displayed
|
|
frequency range. The red marker on the waterfall scale 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. By default lines containing `CQ`
|
|
are highlighted in green, and lines with *My Call* (in this case K1JT)
|
|
in red.

|
.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:
|
|
|
|
- Click or double-click on either of the decoded lines highlighted in
|
|
green. These actions produce 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 frequency marker is moved to the frequency of the CQing
|
|
station.
|
|
|
|
** The *Gen Msg* ("`generated message`") radio button at bottom right
|
|
of the main window is selected.
|
|
|
|
** *Double-click* does all of the above and also activates *Enable Tx*
|
|
so that a transmission will start automatically at the proper time.
|
|
|
|
** You can modify the double-click behavior by holding down the
|
|
*Shift* key to move only the Tx frequency or the *Ctrl* key to move
|
|
both Rx and Tx frequencies.
|
|
|
|
NOTE: You can prevent your Tx frequency from being changed by checking the
|
|
box *Hold Tx Freq*.
|
|
|
|
- Double-click on the decoded message `K1JT N5KDV EM41`, highlighted
|
|
in red. Results will be similar to those in the previous step. The Tx
|
|
frequency (red marker) is not moved unless *Shift* or *Ctrl* is held
|
|
down. Messages highlighted in red 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.
|
|
|
|
- Click somewhere on the waterfall to set Rx frequency (green marker
|
|
on waterfall scale).
|
|
|
|
- Shift-click on the waterfall to set Tx frequency (red 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.
