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
open the WSJT-X File menu, and select Settings
On the General tab, fill in your call and grid square
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
On the Audio tab,
Input: Dax Audio RX 1 (DAX RX Audio) Mono
Output: DAX Audio TX 1 (DAX TX Audio) Both
In SmartSDR,
in the transmit panel, enable DAX (its just below the +ACC button)
set the mode to DIGU
set the filter width to 5K
On the DAX Control Panel, enable audio stream 1, and enable TX for audio stream 1
