Tnx George. I've used the WSJT-X integrated with N1MM+ for several of the digital contests. The problem is that logging should be done through WSJT-X and not N1MM+. People get fooled into thinking that the N1MM+ logging window does the logging when in fact the WSJT-X logging window is primary. I suffered several screw-ups in the early going when doing digital contests. The logging window for WSJT-X carries the last contest worked which is confusing when entering the current contest and the logged QSO gets added.  However, the N1MM+ logging window is current and is the one to use for post-contest download to your logging program.

Another issue is the number of windows that show up. One needs 2 monitors or a really big one to separate the windows. I had to go to the windows tab of N1MM+ to check windows not being displayed.

I managed 75 Qs, mostly in FT4. DX was hard to pull in.

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,

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.
