The current version of hamlib is, 4.3

I had similar delay of TX issues with my FT-1000D and WSJT-X on Linux.  After I updated to hamlib 4.x from version 3.3, my issues went away.  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.

Update to the latest WSJTX and hamlib.  The problem is due to a timing issue in the older versions of hamlib not allowing WSJTX to begin audio
until it receives certain CAT responses from the K3/K3s.   Older
versions of hamlib were doing too many (unnecessary) CAT commands.

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 know nothing about operating in the digital modes but wonder if the delays might be changed with Vox Gain and Delay settings.

Good luck!

Hi Folks,

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.

I really doubt it is due to computer overload, as the only applications running are WSJT-X, MacLoggerDX (my logging program), and JT-Bridge  - all other applications have been ended. Since this happens when I press TUNE, that pretty much eliminates JT-Bridge and MacLoggerDX as the cause. Some hardware and software specifics:

Mac mini, 32 GB RAM, 3GHz processor, 6 cores, Intel Core i5.
Mac OS Big Sur 11.5
WSJT-X 2.4.0
Audio Interface: Tascam US-125M external USB device
Values in the DT column are consistently about 0.1 - 0.4

Wasn’t sure if I should post this here or on the WSJT-X list, but I thought I’d start here. Any ideas?
