[Elecraft] K3 / WSJT-X Delayed Transmit

[Ronnie Hull]

I upgraded to 2.5.0 last night at Jim’s suggestion and it worked! No more delay!

Additionally, all the current rigs were updated in the library.  Note, they are all now four digit radio codes, whereas version 3.3 was mostly three digit radio codes.

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:
