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

Hi Andy, thanks for sending this out. I have been battling the WSJT-X / N1MM+ together issue for a few days now after I foolishly committed to a couple of TVARC board members to get it working in time for Field Day. Research led me to the same steps that you outline in your email. I found the steps in the N1MM+ documentation and other sources. The fly in the ointment for me has been adding in the Icom IC-7300 into the mix. Parameters like baud rate, operating mode and others need to be set correctly. I hope to have all the gotchas figured out and documented soon.

BTW, I am under the impression that rig control is done by WSJT-X, not by N1MM+.

Sadly, the club’s expert on this topic, Rich Erlichman, passed away a few years ago.

73,

George K2DM

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.
