[Elecraft] K3 / WSJT-X Delayed Transmit

[James Bennett]

David -

I’ve played with the VOX Gain to no avail - at zero the rig never transmits, and at 100 (where it has been sitting) I get the delay. Various settings in between have no effect. The Delay controls how quickly the rig goes back into receive mode after speaking. But, thanks for the hints!

I’ve noticed that the radio does not start transmitting right at the start of the 15 second FT8 cycle. It will start anywhere from 2 - 5 seconds into the cycle. I can’t help but think that is not a good thing and could be the cause of an occasional missed QSO. I DO make QSOs but this kinda bothers me. The audio signals are delayed this amount of time, as is the red TX light coming on - I am using VOX . Same thing happens when I press the TUNE button - it takes anywhere from 2-5 seconds for the rig to go into transmit mode.

Since this happens when I press TUNE, that pretty much eliminates JT-Bridge and MacLoggerDX as the cause. Some hardware and software specifics:
