[Elecraft] WSJT FT8 TX not decoded using K3S TX - Rx ok

[Barry]

     Here's something that might help. FT8 only decodes in a certain time 
slot. Make sure your computer is accessing an NTP server and get the 
correct time. Win10 can be set to automatically to access time.nist.gov. 
I spent a long time trying to get a ham buddy going the other day and 
couldn't figure it out. Another buddy picked up on the fact that time 
was not set correctly and he fixed it after which decodes started. I 
missed that one. So, just get the correct time and I infer that should 
fix your problem. You only need tro be seconds off to not work.
