Configuring Commander and WinWarbler for CW and RTTY Operation with an Elecraft K3 or KX3 using CAT Commands

An Elecraft K3 or KX3 can be directed to transmit CW, report decoded CW, transmit RTTY, and report decoded RTTY via CAT commands, eliminating the need for any external interface. Doing so requires both WinWarbler and Commander to be running, with Commander configured to control an Elecraft K3 or KX3. Note that a connected P3 configured to display decoded CW or RTTY interferes with the K3's ability to report decoded CW or RTTT to Commander, and thus must be disabled.

Transmitting and Receiving CW

To enable WinWarbler to transmit CW via CAT command, set the Keying panel on the CW Tab of its Configuration window to Xcvr Ctrl App

To enable WinWarbler to display CW decoded by a K3 or KX3,

  1. Configure your K3 or KX3 to decode CW, as described in the CW Text Decode Setup section of your K3 or KX3 owners manual

  2. In the Radio panel on the General tab of Commander's Configuration window,

    1. if the Command interval is set to more than 200, set it to 200

    2. check the Interrogation box

    3. check the Convey decoded CW to WinWarbler box

  3. On the CW tab of WinWarbler's Configuration window, check the display xmit/rcv characters box

  4. On WinWarbler's Main window, set the Operating Mode panel to CW

Decoded CW will appear in the CW receive pane on WinWarbler's Main window. Decoded information can be captured by double-clicking.

Transmitting and Receiving RTTY

To enable WinWarbler to transmit RTTY via CAT command, on the External Modem tab of its Configuration window,

  1. Place the K3 or KX3 in DATA mode, FSK D submode

  2. In the FSK sub-panel in the Modulation and transceiver mode panel on the RTTY tab of WinWarbler's Configuration window,

    1. click the LSB button

    2. set the Xcvr Mode selector to the right of the LSB button to RTTY

    3. set the Mark offset to -2125

    4. set the Optimal Offset to 2210

      • for a K3, set the FSK Control to the serial port you are using for FSK keying

      • for a KX3, set the FSK Control to none

  3. On the General tab of Commander's Configuration window, set the RTTY sub-mode to FSK. With the transceiver's DATA submode set to FSK D, you may need to ensure that the K3's or KX3's FSK speed is set correctly (45 bps is the normal setting for amateur RTTY).

Characters typed into WinWarbler's Main window's Transmit pane with the External Modem receive pane (denoted by an X in its left margin) active will be transmitted via your K3 or KX3.

To enable WinWarbler to display RTTY decoded by a K3 or KX3,

  1. Configure your K3 or KX3 to decode RTTY, as described in the Data Text Decode Setup section of your K3 or KX3 owners manual

  2. In the Radio panel on the General tab of Commander's Configuration window,

    1. if the Command interval is set to more than 200, set it to 200

    2. check the Continuous interrogation box

    3. check the Convey decoded RTTY to WinWarbler box

  3. on the External Modem tab of WinWarbler's Configuration window,

    1. set the Model selector to Xcvr Ctrl App

    2. check the RTTY panel's enabled box

  4. On WinWarbler's Main window, set the Operating Mode panel to RTTY

Decoded RTTY will appear in the the External Modem receive pane (denoted by an X in its left margin) on WinWarbler's Main window. Decoded information can be captured by double-clicking.
