I know some are having trouble setting up WSJT-X with HRD 6.9 but it is rather simple. Here is what I did.
Also, if you set it to auto-log log it will log directly when you make a contact. If you click for it to notify you first, a box will pop up that you have to click to log the contact.
WSJT-X / HRD / HRD Alert — Final Working Configuration K9OQ
WSJT-X Settings
Menu path: File → Settings → Reporting → Network Services
| Setting | Value |
| Prompt me to log QSO | Checked |
| Accept UDP requests | Checked |
| UDP Server address | 224.0.0.1 |
| UDP Server port | 2237 |
| Outgoing interfaces | Ethernet Loopback |
| Multicast TTL | 1 |
| Enable logged contact ADIF broadcast | Checked |
| Secondary UDP Server (deprecated) | Enabled |
| Secondary address | 127.0.0.1 |
| Secondary port | 2333 |
Explanation:
- Port 2237 multicasts decodes to HRD Alert.
- Port 2333 sends ADIF QSO data directly to HRD Logbook.
HRD Logbook Settings
Menu path: Tools → Configure → QSO Forwarding
| Section | Setting | Value |
| UDP 5 – Receive QSO notifications | Unchecked | |
| UDP 9 – Receive logbook changes using UDP from other logging programs | Checked | |
| Receive Port | 2333 | |
| Target Database | HRD My Logbook | |
| Use | MyStation | |
| UDP Send (top section) | Unchecked |
This is the active receiver for WSJT-X ADIF broadcasts.
HRD Alert Settings
Menu path: Options → Multicast UDP Settings
| Setting | Value |
| IP address | 224.0.0.1 (may display as 224.0 .0 .1) |
| Port | 2237 |
| Default Multicast | Selected |
| Default Localhost | Unchecked |
HRD Alert listens to WSJT-X’s multicast feed for real-time decodes.

How It Flows
Multicast (224.0.0.1:2237)
┌────────────┐

Test Checklist
- HRD Alert shows decodes within 10–15 seconds after WSJT-X starts.
- When you log a QSO in WSJT-X, it appears in HRD Logbook instantly.
- No crashes, no freezes, no duplicate entries.
If you want to add Grid Tracker or similar software, just use the same multicast address 224.0.0.1 and the appropriate port number 2237. All should work well with HRD 6.9 with no problem. Make certain the wsjtx setting is set to Ham Radio Deluxe, not your radio. Also, make certain that if you have more than one radio on HRD, the radio you are using with WSJT is set as the selected radio in HRD.
