User Guide: Connecting WSJT-X | JTDX + GridTracker + WRL Cat Control with World Radio League #
This guide walks you through setting up WSJT-X or JTDX so that it streams your logged QSO’s directly into your World Radio League logbook.
1. Sign Into World Radio League #
-
Open World Radio League and log into your account.
-
Keep this window open while you configure everything
2. Download the WRL Cat Control App #
- Go to the integrations page (https://app.worldradioleague.com/integration) and download the latest cat control app
3. Start the WRL Cat Control app #
- Initialize your radio connection by selecting your Radio, COM Port & Baud Rate (you can follow this Guide if you need a detailed breakdown.
-
Important Notes (For Windows Users):
- Go to ‘Device Manager’ –> ‘Ports (COM & LPT)’ and right click on your COM port for your radio, then click ‘Properties’
- Under the ‘Port Settings’ Tab, make sure you have set the baud rate under the ‘Bits Per Second’ drop down that you’ve set inside your radio settings (do this for both COM ports for your radio, if you have more than 1).
- If you have a ‘Power Management’ Tab make sure to uncheck/disable the two options here that say “Allow the computer to turn off this device to save power” & “Allow this device to wake the computer”
- FTdx101D/MP | FTdx10 | FT710 Users:
- In your radio settings in the “Operation Settings” menu –> “General” make sure to set the ‘CAT RATE” to “38400” (or whatever you’ve set in the ‘Port Settings’ tab in device manager above)
- In your radio settings in the “Operation Settings” menu –> “General” make sure to set the ‘CAT TIME OUT TIMER” to “100msec” (10msec is too fast and will cause time-out errors)
- In your radio settings in the “Radio Settings” menu -> “MODE PSK/DATA” set the “DATA MOD SOURCE” to “REAR”
- In your radio settings in the “Radio Settings” menu -> “MODE PSK/DATA” set the “REAR SELECT” to “USB”

Make sure everything is set according to the screenshots below
- Under the “General” settings tab set the UDP port ‘Receive UDP Messages” to “2333” & “Forward UDP Messages” to “2238”
- Under the “Logging” settings tab set the very last option “HRD Logbook” (we are using HRD Logbook since GridTracker doesn’t have a WRL option, currently) as enabled (check the ‘Log’ column) and set the UDP Port to “2238” *This is important*

6. Close WSJTX | JTDX, GridTracker, & WRL Cat Control #
- After setting up everything above you’ll need to close everything out and then re-open it all in the following order:
- Start WRL Cat Control & click ‘Start Radio Connection’ (if you’re using rig control), then click the settings icon (gear icon) and click ‘Start Listening’ under the WSJTX tab.
- Start GridTracker and let it load completely
- Start WSJTX or JTDX
7. Start Logging #
- At this point if you have followed this guide, everything should be setup to correctly talk to each other.
- Make a contact via WSJTX or JTDX, when the “Log Contact’ dialog box pops up after completing a QSO; add your comment and any other data you normally log and click the ‘OK’ button to log the contact.
- The contact should show up in your WRL logbook.
#
Understanding Mode Logging #
-
You may notice FT4 contacts logged as MFSK.
-
This is expected:
-
FT4 is a sub-mode of MFSK.
-
Many logging programs (including World Radio League) use MFSK as the universal standard to ensure compatibility. *we will be changing this soon to where the contacts are logged as MFSK as the mode & FT4 as the submode but shown to the user (in their logbook) as FT4 *
