WinWarbler Online Help Contents
Using your soundcard's analog-to-digital and digital-to-analog conversion capabilities, WinWarbler allows you to conduct RTTY QSOs. To begin RTTY operation, click the RTTY button in the Mode panel located in the lower right corner of WinWarbler's main window. You can specify a set of commands to be executed whenever WinWarbler switches to RTTY mode by setting up a RTTY startup macro
WinWarbler provides two independent means of sending and receiving RTTY signals:
When first installed, soundcard RTTY is enabled and RTTY via external modem is disabled. When you click the RTTY button (in the main window's Mode panel), you'll see a single receive pane and a single transmit pane; the channel label to the left of the receive pane is S (for Soundcard RTTY). WinWarbler uses JE3HHT's MMTTY engine; an icon representing this application will appear in your Windows task bar while soundcard RTTY is in progress; note that the MMTTY engine can take much longer to start and stop if a virus scanner is running on your PC. Once MMTTY is running, WinWarbler graphically presents a 4 kHz waterfall display, allowing you to specify your mark frequency by simply pointing and clicking with your PC's mouse.
While WinWarbler supports soundcard RTTY operation immediately after installation, additional controls are provided -- including access to MMTTY's demodulation parameters.
If you have an external modem connected to your PC via a serial port, you can enable a second receive pane -- its channel label is X (for eXternal modem). 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 a receive pane selects it, meaning that subsequent transmission will use that pane's associated mechanism (soundcard or external modem); the currently selected pane is distinguished by a red channel label on its left-hand border. If Commander is running, selecting a pane will place your transceiver in the appropriate mode, as specified by soundcard and external modem configuration settings.
External modem commands are specified in files located in WinWarbler's Modems subfolder. WinWarbler includes files for the KAM and PK232. You can modify these files, or create files for other modem models using a simple command syntax.
