[Elecraft] K3 And WSJT-X FT8 Timing

[Dennis Moore]

How are you keying the K3, VOX or PTT?

It's not clear from the email, are the K3 and KX3  on separate computers 
on just different sound cards in the same computer?

It is between 1.5 and 2 seconds after the beginning of the new 15 second sequence! In that short duration, I am hearing other stations’ signals coming through on my headphones, so I know that other folks are getting their rig to transmit right at the start of the 15 second sequence. If mine is coming on 1.5 - 2 seconds late, I’m thinking I may not always get decoded on the other end.
