<h2 style="text-align: center;">CW Mode</h2>
<h4>Carrier Frequency</h4>
Fldigi generates CW by inserting a keyed tone at the current
waterfall audio frequency. The CW carrier frequency is the USB
carrier + the audio frequency, or the LSB carrier -
the audio frequency. If fldigi is tracking and receiving a CW
signal on the waterfall your transmitted signal will be exactly on the
frequency of the other operator. You probably cannot use your
transceivers CW filter unless that filter can be used with the SSB mode.<br>
<h4>QSK and the TAB KEY</h4>
If you are operating QSK with a separate transmitter / receiver you can
very quickly stop your transmit signal with the TAB key. In
the
CW mode only the TAB key causes the program to skip over the remaining
text in the transmit text buffer. The text that is skipped
will
be color coded blue. The program remains in the transmit mode
(PTT enabled), but since the buffer is now empty no A2 CW signal is
generated. Code transmission will then restart with the very
next
keyboard closure of a valid CW character. <br>
<h4>Pausing transmit<br>
</h4>
The Pause/Break momentarily key stops sending text. Pressing it again resumes transmission.<br>
<h4>Aborting transmit<br>
</h4>
The Escape key is used to immediately stop text transmission. The Tx buffer is cleared.
<h4>WPM adjustment</h4>In CW mode the status bar is changed to include
a transmit WPM adjuster. Use the arrow buttons or the
mouse.
Mouse wheel up/down changes transmit WPM by +/- 1. Hold the shift
and mouse mouse wheel changes transmit WPM by +/- 10. The "*"
button immediately to the right of the WPM adjuster is used to toggle
between the current and the default transmit WPM.<br>
<br>
The transmit WPM can also be adjusted with three hot keys:<br>
<ul style="text-align: left;">
<li>Numeric keypad "+" increases the transmit WPM by 1</li><li>Numeric keypad "-" decreases the transmit WPM by 1</li><li>Numeric keypad "*" toggles between the selected transmit WPM and the default transmit WPM</li>
</ul>
The "Default" control on the CW tab sets that default value. If during a
QSO you needed to slow down to give the other op a better chance to
copy what you are sending, just hit the "*" on the numeric keypad and
the cw code will immediately switch to sending cw at the set default
value (18 wpm in this example). Press the "*" again to return to
back to the cw speed that you were previously using.<br>
<br>
Each time the transmit WPM is changed the receive decoder WPM tracking
is reset to the new transmit WPM. This allows you to quickly
force the decoder to a new WPM range.<br>
