Re: [Elecraft] K3 / WSJT-X Delayed Transmit
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. 73, Don W3FPR On 10/11/2021 3:23 PM, James Bennett via Elecraft wrote: 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.

It's a problem between WSJT-X and hamlib. WSJT-X was sending more rig control commands than necessary. Also, don't tell WSJT-X to do anything to the K3 except do the split thing, which minimizes harmonic distortion caused by overdriving the rig's audio input or modulator. 73, Jim K9YC __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

Re: [Elecraft] K3 / WSJT-X Delayed Transmit
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. 73, ...
