I received an inquiry from Darryl, VK3DAZ (Australia), asking about interfacing the popular JT65 program WSJT-X with the Yaesu FTdx3000. I’ve been able to make my ‘3000 work directly with WSJT-X as a standalone, or with Ham Radio Deluxe (HRD) in the background as a rig controller. This post shows how I do it directly with WSJT-X.
First, of course, is to make sure that the computer and the ‘3000 are talking properly. If they do for HRD, then the same COM setting should work for WSJT-X. Be sure to use the “enhanced” COM port (note this is true even if you are using the USB attachment to the radio). If you have trouble setting up the ‘3000’s internal soundcard, take a look at this site here for an excellent explanation.
Second, make sure you’re using the latest version of WSJT-X. As of today, it’s v1.5. You can download it by clicking here.
The following screen is the Radio Setup page, reached by clicking File, then Settings, then choosing the Radio screen. I will go through each detail.
- For rig, choose FT-DX5000, because the FTdx3000 is not listed. Leave the Poll Interval at 1 sec unless you have strong reason to change it.
- Under CAT Control, select the serial port that is the “enhanced” port. Note this is true even if you’re using the USB cable (which I am).
- Choose a baud rate for communications between the computer and the ‘3000. NOTE THAT this must match the setting in MENU 038 CAT RATE. I use 38,400, the max rate the ‘3000 will accept.
- Set Data Bits to Eight and Stop Bits to Two. Set Handshake to None.
- Check the box for Force Control Lines and check the box for RTS. NOTE THAT this must match the setting in MENU 040 CAT RTS, which must be set to ENABLE
- In the next column, under PTT method, select CAT.
- The Transmit Audio Source is grayed out
- Under Mode, select Data/Pkt. NOTE THAT you must place the rig into the DATA USB mode. I have this set up in one of the band-stacking registers. WSJT-X will not select the correct register, so be sure to select which register prior to using WSJT-X.
- I have Split Operation set to None. You can consult the WSJT-X online manual for more information.
- When you’re ready, click on the Test CAT button. If WSJT-X is satisfied, the button will turn green. Select the Test PTT button. Your transceiver should go into transmit mode, but no data will be transmitted.
- Click OK and you’re done!
If you would like to set levels, on the main screen you can select the Tune button. That will put the transceiver into transmit mode and also send a signal. You can set up your transceiver with this. Speech processing should be turned off, the Mic Gain should be set so that the rig does not go into ALC, mic equalization (MIC EQ) shoul.d be set to OFF, digital noise reduction (DNR) should be set to OFF, the digital notch filter (DNF) should be set to OFF, and you need to back the power off to something like 25 watts. After that, have fun!
Note that the ‘3000 has only a 2400 Hz bandwidth when in the data mode. That’s unfortunate, as WSJT-X can handle bandwidths up to 4 kHz or more.
