WinWarbler PSK Transmission

WinWarbler Online Help Contents

Transmission frequency can be set to the frequency of the selected receive channel by clicking the Set Freq button in the transmit panel, or by striking the F1 key. Checking the net setting in the Transmit panel causes transmission frequency to automatically follow the selected receive channel's frequency. If net is unchecked, the transmission frequency appears as a red trace in the waterfall display. If the waterfall right-click box is unchecked, right-clicking in the tuning display unchecks the net setting and sets the transmission frequency; if the waterfall right-click box is checked, you must depress the CTRL key while right-clicking in the tuning display to set the transmission frequency.  The transmission frequency is continuously displayed in the transmit panel.

If net is checked, you can optionally designate one of the three receive channels as the QSO channel. If you've specified a QSO channel, then no matter which receive channel is active when you take an action that initiates transmission, WinWarbler will activate the QSO channel prior to transmitting. Thus you can be copying your QSO partner with one receive channel while using (and thus activating) another receive channel to locate your next QSO. When you transmit in response, WinWarbler will automatically activate the QSO channel, assuring that your response is transmitted on the correct frequency. Clicking in a receive pane while depressing the CTRL key designates the associated channel as the QSO channel. The QSO channel selector is located in the lower-left corner of the Main window's PSK Receive panel. If net is checked and no QSO channel is designated, then transmission occurs on the frequency of the currently active receive channel.

If Commander is running, checking the Transmit panel's split box and net box will place the transceiver in split mode, and when transmitting set the transceiver's VFO B so that transmission occurs on the optimal audio offset specified in the optimal offset sub-panel of the Receiver panel on the Config screen's PSK tab. This technique is helpful when using Broadband Decoding, as it allows transmission on the optimal offset without changing the receive frequency.

Information to be transmitted is entered into the Transmit Pane by direct keystroke; to clear information entered into the Transmit Pane, click the X button on the transmit pane's right margin. To increase the number of text lines visible in the transmit pane, click the resize button on the Transmit Pane's right margin. Sixteen macro buttons provide an alternative means of supplying information to be transmitted; macros can automatically transmit your callsign, the callsign, name, and QTH of the station with whom you are in QSO, incoming and outgoing signal reports, the peak IMD reading, the current UTC time or date, and the contents of files.

To initiate transmission using the PSK modulation specified by the transmit modulation setting, click the Start button in the transmit panel, or strike the F2 key, or strike the Insert key; the Start button is immediately disabled, and remains so until transmission terminates. Initiating transmission enables the transmit panel's CW ID, Stop, and Abort buttons. As information is transmitted, its displayed in the currently selected receive pane using a white font to differentiate it from received information. 

To force CW identification to be sent when transmission is terminated, click the CW ID button in the transmit panel, or strike the F3 key; the CW ID button is immediately disabled, and remains so until transmission terminates. The identification information sent in Morse code is specified by the CW identification string setting; the rate at which this information is sent is controlled by the CW identification speed setting.

To automatically terminate transmission after all information to be transmitted has been sent, click the Stop button in the transmit panel, or strike the F4 key, or strike the Enter key while depressing the Ctrl key. You can do this as soon as transmission has begun.

To immediately terminate transmission, click the Abort button in the transmit panel, or strike the Esc or End key. Any un-transmitted information is discarded.

To facilitate tuning, you can set transmit modulation to tune by checking the tune checkbox in the transmit panel. Un-checking the tune checkbox returns transmit modulation to its previous value.

If the auto-stop after idle box is checked, transmission is terminated after idle characters are sent for 15 consecutive seconds; tuning does not activate this mechanism.

Clicking the right mouse button on the transmit display pane produces a pop-up menu with two commands:

Striking Ctrl-V in the Transmit Pane also initiates the Paste (insert Clipboard into Transmit Pane) operation.

To facilitate compliance with station identification requirements, WinWarbler keeps track of how much time has passed since you last identified on each channel for which a QSO is in progress. A channel is deemed to be "in QSO" from the point in time at which you start it until you end it. If 5 minutes elapses without your transmitting an identification, a small black square containing the channel number in yellow appears in the transmit panel's ID reminder; if 10 minutes elapses without your transmitting an identification, the channel number's color changes from yellow to red. Transmitting your call -- by keying it into the transmit pane, by pasting it into the transmit pane, or by invoking a macro -- resets the current channel's timer and removes any visible reminder.
