[TVARC] Using N1MM as logger for FT-8 contacts made via WSJIT

[Andy McClary]

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

  1.
Open WSJT‑X → Settings → Reporting
  2.
Enable:
     *
✓ Enable UDP Server
     *
✓ Accept UDP Requests
     *
✓ Enable Logging
  3.
Set:
     *
UDP Server Address: 127.0.0.1
     *
UDP Server Port: 2333 (default for WSJT‑X → N1MM)

✅ 2. Configure N1MM to Receive WSJT‑X QSOs
N1MM must be told to accept WSJT‑X data.
N1MM Settings

  1.
Open N1MM+ → Config → Configure Ports, Mode Control, Audio, Other
  2.
Go to the WSJT/JTDX Setup tab
  3.
Enable:
     *
✓ Accept UDP packets from WSJT‑X
  4.
Confirm:
     *
UDP Port: 2333
     *
IP Address: 127.0.0.1
  5.
Restart N1MM after enabling (required).

✅ 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:

  *
Shows WSJT‑X decodes
  *
Lets you initiate QSOs
  *
Logs QSOs automatically into N1MM
  *
Provides dupe checking, mult highlighting, scoring, etc.

✅ 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:

  1.
WSJT‑X → Reporting → Enable UDP Server (2333)
  2.
N1MM → Config → WSJT/JTDX Setup → Enable UDP input
  3.
Open WSJT Decode List Window
  4.
Complete QSO in WSJT‑X → Auto‑logged in N1MM

This is the officially supported method and works reliably for FT8/FT4 contesting.
