8600 and JTDX/WSJT xmit jitter on digi modes

I must have something set up incorrectly here also. When using FT8 I notice on xmit my signal form "jumps/jitters. Not at a regular interval, randomly. I have someone say it causes splatter. I've tried lowering the various DAX settings but the jitter remains. I opened a ticket with the help desk but they blew me off apparently. Not sure what I have set incorrectly. I had this one time before with my 6600 but a software update came out and the problem disappeared. When I first bought the 8600 no problem. Since version 4 came out jitters.

    Update to SmartSDR 4.2.20 and see if you see the same thing.

    I am using 4.2.20. The last two versions have had the jitter. I did have an oddity. Using my desktop I was not able to upgrade the radio software. I was able to install the new version to the desktop but when trying to upgrade the radio I got a file could not be found error. I had to use a laptop to get the software to update the radio.

    something is getting in the way then. You'll want to open a support ticket.

    Sometimes, the Jitter issues are visual part of a more significant problem. SmartSDR might not be the root cause but the victim. Things like using the internal video card at a high resolution that then that requires the CPU to work harder to draw the screen data. This is why a computer with its own video card performs much better.

    Computer is an i9 processor, there is a separate video card. I have opened a ticket, but no one has contacted me. I get an email about tickets being prioritized. Apparently, my problem is not a priority. I have no idea why my desktop cannot be used to upgrade the SDR software in the radio up to the last two software updates there has never been an issue.

    If you opened a ticket and received a ticket number, then they have it, but they are super busy. Sometimes we get caught in a lot of hand holding/elmering and a single call can take an hour especially if the customer is new.

    Do you have another computer you can test with? It sounds like your AV or Firewall is blocking something. If this was a systemic problem, then thousands of customers would be reaching out to us.
