Your time is off and FT4 has pretty tight timing tolerances.The vast majority 
of your DT values in your decodes should be < 0.5 seconds for best results.
If you're on Windows install Meinberg NTP and ensure you selection an 
appropriate location in the pull down that shows up during installation.de Mike

hamspots.net will show you how others see you.  There can be a significant 
difference in receive and transmit DT values with some buggy setups.de Mike

 Hi guys
I hope someone can make sense of this as I've completely lost all decode on FT4.

During WWDIGI my log contained 250 odd QSO's all bands, most of those were on 
FT4.
On Monday 1st sept, I set up N1MM + WSJT-X for the RSGB trial FT4 contest on 
80m.
I did some tests with a friend on the south coast and decoded ok with 100w.
However afterward others called in and I could not decode them.
During the RSGB trial FT4 contest (one hour duration) the waterfall was full of 
stations.
I actually worked G4OGB early on but no other Stn was decoded though I could 
see plenty were calling me on the waterfall.
I've reloaded 64bit software on an i7 Nuc, with Microham keyer, K3, with this 
setup I've worked a few Thousand QSO's.

Please note
Running just WSJT-X and FT8 decodes great.
I tried this yesterday on 20m, switching to FT4 14080.00 lots of stn's active 
....no decode!!!
