Having trouble with N1MM+ and WSJT-X integration during contests - specifically the dupe checking isn't working properly and multipliers aren't being highlighted correctly. Using the standard UDP port 2237 configuration and followed the official setup guide. The contest mode is set to include DIGITAL modes and the WSJT Decode List window opens but the highlighting seems intermittent.

Running IC-7300 with N1MM+ 1.0.9995 and WSJT-X 2.6.1. Have configured both the Mode Control page and WSJT/JTDX Setup page properly. Anyone else experiencing similar issues with recent versions?

Check that JTAlert isn't running simultaneously - N1MM and JTAlert can't share the same UDP port. Also verify both programs are using port 2237 in their respective settings. I had the exact same problem last month.

Make sure frequency and PTT are working correctly in N1MM+ before starting WSJT-X. For the IC-7300, ensure the Mode Control PSK setting is set to AFSK-R, not USB. This caught me during ARRL RTTY.

Try using Tools > Rescore Current Contest to fix any FT8/FT4 QSOs that weren't assigned the correct score. There's an updated N1MMWSJTInstructions.pdf file in the Additional Support directory that covers recent changes to the integration setup.
