ugh this is driving me nuts. had everything working fine for the cq ww rtty contest last month but now n1mm wont pull the qsos from wsjt-x automatically. the udp settings look right, both programs are running, but nothing. anyone else seeing this or am i missing something obvious here? running latest versions of both

check your port numbers - i had the same issue after a windows update messed with my firewall settings. also make sure you have the right multicast address in both programs, sometimes they get out of sync. what version of n1mm are you running?

Yeah I've been there too. Sometimes you gotta restart both programs in the right order - WSJT-X first, then N1MM. Also double check that "accept UDP requests" is enabled in N1MM under the digital interface tab. Pain in the rear when it stops working randomly but usually its something simple
