[Elecraft] K3 / WSJT-X Delayed Transmit

[Don Wilhelm]

Jim,

Two possible fixes:
1) Use PTT via CAT command - most digital applications provide for it.
2) Check that your audio levels are sufficient - for the Elecraft gear, 
you should have 4 bars of ALC solid with the 5th one blinking.  See the 
full explanation on my website www.w3fpr.com.

>>> Wondering if someone on the list might be able to solve this one. I’m using a K3 and while CW is my main passion, I do dabble in FT8 occasionally. 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:
