[Elecraft] K3 And WSJT-X FT8 Timing

[RIchard Williams]

 Richard,
I had a similar problem with the K3S not stopping transmit.  Finally fixed it by changing the stop bit in the radio settings from two to one.

 Maybe I’m missing something, but the “timing” problem with which some of us are fighting has nothing to do with computer clock accuracy. Even if the computer time is off, it’s the only time reference WSJT-X has to work with.

So the instant the computer tells the software it’s time to transmit, BANG! WSJT-X goes into transmit RIGHT NOW, as it should, late or not, the software doesn’t know and doesn’t care.

Our problem is that when WSJT-X goes into Transmit at the top of the new segment and tells the K3S to transmit, the K3S DOESN’T transmit. Its almost always late by 2 or 3, sometimes 4 or 5 full seconds. In my case, it eventually doesn’t transmit AT ALL!

That’s not a software problem or a computer clock problem. It looks like a K3S problem, and I’d sure like to see the solution before I dump this radio.

The software should handle decodes with a DT up to 2.0 seconds, but in many cases this depends largely {very largely in fact} on signal quality.  Both as transmitted and received.
