I have delayed posting this as I was hoping that I would see the same issue
posted by another user.

I am running a K3s and the issue is with the USB com port. First, the com
port assignment is com 27 which seems strange for my simple PC set up. I
have tried to go into the Windows control panel and change it to a lower #
available port, but it will not take, but this is not the issue.

My problem is that the com port will sometimes be recognized by the K3
utility or other programs as either 9600 or 38400 baud on a totally random
basis. If I connect at 9600 the K3s will after a while change its port rate
to 38400 and I have to close the program that I am using and re start it at
38400. This will work fine for a while until the K3s then resets it baud
rate again to 9600 and I have to re start the program that I am using.

Using programs like WSJT-X which now has rig control is very frustrating
and I usually just turn off the rig control and use the com 27 only for ptt
control. I have even had issues while using WSJT-X and the rig control,
that will change the K3s com port to a new baud rate between Rx & Tx

Are there any suggestions out there? I only have a PC in the shack and
can’t try another PC. Is this a K3 issue of something with my PC?
