WinWarbler RTTY Reception Via External Modem

WinWarbler Online Help Contents


Soundcard RTTY makes an excellent tuning indicator for your external modem; simply enable it, and refer to the soundcard RTTY tuning section.



Information decoded by your external modem is sequentially appended to the external RTTY receive pane, designated by a channel label of X along its left margin. This receive pane has a vertical scrollbar along its right side, allowing you to view information which has scrolled off the pane. The only limit to each receive pane's information retention is the amount of free space on the disk drive hosting WinWarbler. You can change the font name, style, size, and color used to display this information via WinWarbler's display settings

If you are simultaneously receiving RTTY via both soundcard and external modem, their receive panes are separated by a "splitter" bar. You can move this splitter bar by placing the mouse cursor overtop it; when the mouse cursor changes to a double-headed arrow, use the left mouse button to drag the splitter to its desired location, reallocating available screen space between the adjacent receive panes. Clicking the right mouse button over a receive pane produces a pop-up menu that includes an Equalize all receive panes entry; selecting this entry equally divides the available space between the soundcard RTTY receive pane and the external modem receive pane.

With both soundcard and external modem receive panes active, you can decode the same signal simultaneously (diversity decoding), or simultaneously monitor nearby signals  -- such as a DX station and her pileup. Clicking the soundcard RTTY or external modem receive pane selects it; the currently selected pane is distinguished by a red channel label on its left-hand border. On the Main window, the RTTY receive & transmit panel's QSO selector lets you specify whether transmission is accomplished via soundcard RTTY or via the external modem:

QSO selector Transmission
  via selected pane
S via soundcard RTTY
X via external modem

With the QSO selector set to S or X, the QSO Info panel merges the information captured from the soundcard RTTY and external modem receive panes; otherwise, the information captured from each pane is separately maintained.

Because RTTY uses the LTRS character to switch from sending characters in the figures set  to characters in the letters set, and the FIGS character to switch from sending characters in the letters set to characters in the figures set, a garbled LTRS or FIGS character can result in the misinterpretation of the subsequent word. To compensate for this, clicking on a received word while depressing the Ctrl key will replace the each character in that word with its analog in the opposite set, and toggle the character's underlining in the Receive Pane. If you receive a garbled word, try Ctrl-clicking it; if that doesn't make it intelligible, Ctrl-click it again to return it to its original state. 

If the station you're monitoring is transmitting reversed tones, check the Receive panel's reverse box; this automatically updates the receive setting in the Reverse sub-panel on the Config window's RTTY tab.

To freely scroll a receive pane, you must first suspend the pane's display of incoming information; do so by clicking on the color-coded panel to the left of the pane you wish to scroll. A pane's channel label blinks while it is suspended. To resume the display of incoming information -- including that which arrived while the display was suspended, click on the color-coded panel to the left of the pane. You can suspend a pane for up to an hour without loss of incoming information.

To copy text from a receive display pane to the Windows clipboard, use the standard Windows left-click and drag gesture. This gesture automatically suspends the pane. Click on the color-coded panel to the left of the pane to resume the pane's display of incoming information.

To facilitate logging, double-clicking on a word in a receive pane copies that word to the appropriate QSO Info panel item. 

The contents of the QSO Info panel items are maintained separately for each receive channel; whenever you switch channels, these items are updated to reflect whatever information you have captured from that channel. This makes it easy to incrementally capture information as you monitor several QSOs.

Clicking the right mouse button over a receive pane produces a pop-up menu with four commands:


Transceiver Control

WinWarbler automatically interoperates with Commander, an transceiver control program for Alinco, Elecraft, Flexradio, Icom, Kachina, Kenwood, TenTec, and Yaesu radios. If WinWarbler and Commander are running simultaneously, WinWarbler's xcvr freq selector will automatically track your transceiver's frequency as you QSY; it does not matter in what order the two programs are started. 

If the transceiver controlled by Commander is an Elecraft K3 or KX3 in RTTY or RTTY-R mode, you can configure Commander to convey decode RTTY text to WinWarbler. Setting the model panel selector to Xcvr Ctrl App will configure WinWarbler to display this text in its external RTTY receive pane.


Displaying Characters Decoded by Other Applications and Devices

Setting the model panel  to Decoder App will configure WinWarbler to display decoded RTTY characters received via DDE commands

Setting the model panel  to External will configure WinWarbler to display decoded RTTY characters received via an RS-232 port.
