Using WSJT-X with Commander and a Flex-6000 Series Transceiver

de Jim NM1W

WSJT-X is an application that implements JT9, a new mode designed especially for the LF, MF, and HF bands, as well as the popular JT65 mode. Both modes were designed for making reliable, confirmed QSOs under extreme weak-signal conditions. WSJT-X operation uses only one VFO whose frequency is shifted as required during transmission and reception.

Configuring WSJT-X

  1. open the WSJT-X File menu, and select Settings

    1. On the General tab, fill in your call and grid square

    2. On the Radio tab,

      • select Rig: DX Lab Suite Commander

      • poll interval: 1s

      • PTT: CAT

        • If you have a separate COM port connected to a device with PTT capability (e.g. a Winkeyer) you can optionally configure WSJT-X to use it, as doing so will provide more accurate PTT timing. If you choose this approach, however, don't configure Commander to use the same COM port for PTT, as WSJT-X would then be denied access to the COM port.

        • If Commander cannot switch your radio between reception and transmission, then consider an alternate selection for PTT method, e.g. VOX.

      • Mode: Data/Pkt

      • Split Operation: Fake it

    3. On the Audio tab,

      • Input: Dax Audio RX 1 (DAX RX Audio)  Mono

      • Output: DAX Audio TX 1 (DAX TX Audio)  Both

  2. In SmartSDR,

    1. in the transmit panel, enable DAX (its just below the +ACC button)

    2. set the mode to DIGU

    3. set the filter width to 5K

On the DAX Control Panel, enable audio stream 1, and enable TX for audio stream 1
