if Commander isn't running and you're transmitting via AFSK, set your transceiver's mode to LSB
if Commander isn't running and you're transmitting via FSK, set your transceiver's mode as shown in this table

Annotated Main window in RTTY Mode
Operating in RTTY
Click the RTTY button in the Main window's Operating Mode panel. To decode a signal in the Receive Pane,
click on the Mark frequency of the desired signal in the Waterfall display; the yellow traces that indicates the Receive Pane's Mark and Space frequencies will be positioned over the signal in the Waterfall display, and decoded characters will appear in Receive Pane
With the Transmit panel's Net box checked, WinWarbler will transmit on the Receive Pane's frequency. To transmit,
click the Start button in the RTTY transmit panel
type the characters to be sent in the Transmit Pane
click the Stop button in the RTTY transmit panel
Your transceiver should switch from reception to transmission, transmitted characters should appear in the Receive Pane, and your transceiver should switch from transmission to reception after all characters have been sent. You can also transmit by constructing and invoking macros.
Note: with the RTTY Receive panel's AFC box checked, the Receive Pane will automatically adjust its Mark frequency to track any changes in the received signal. To prevent your transmission frequency from also being adjusted by this AFC action, uncheck the RTTY transmit panel's Net box once a QSO has begun.
