Somebody asked this question, but I can't remember who...  so apologies for sending this to the reflector instead of directly...

Short answer:  To send QSOs from WSJT‑X to N1MM Logger+, you enable WSJT‑X’s UDP Broadcast and N1MM’s WSJT Decode List interface. Once configured, every completed QSO in WSJT‑X is automatically logged into N1MM+.
Below is the exact, step‑by‑step setup based on the N1MM documentation. Citations included.
✅ 1. Enable WSJT‑X → N1MM Logging (UDP Broadcast)
WSJT‑X sends QSO and decode data to N1MM using UDP packets. N1MM listens on UDP port 2333 for WSJT‑X.
WSJT‑X Settings
✅ 2. Configure N1MM to Receive WSJT‑X QSOs
N1MM must be told to accept WSJT‑X data.
N1MM Settings
✅ 3. Use the WSJT Decode List Window in N1MM
N1MM provides a dedicated interface for WSJT‑X called the WSJT Decode List Window. This is the bridge between WSJT‑X and N1MM.
Open it in N1MM: Window → WSJT Decode List
This window:
✅ 4. How Logging Works
When WSJT‑X completes a QSO (73 exchanged), it sends an ADIF record to N1MM in this format:
Code
<command:3>Log<parameters:nnnn>ADIF_DATA
N1MM inserts it into the current contest log.
Supported fields include CALL, QSO_DATE, TIME_ON, MODE, FREQ, RST, GRID, etc.
🧩 5. CAT Control Note
N1MM should control the radio, not WSJT‑X. WSJT‑X reads frequency from N1MM through the interface. This avoids CAT conflicts.
🎯 Summary
To send QSOs from WSJT‑X to N1MM:
This is the officially supported method and works reliably for FT8/FT4 contesting.
