I just had this problem today after "upgrading" to Windows 10 Ver 1809. Windows told me the COM port was closed, even though it showed up in device manager. A reboot fixed it. YMMV _____________ 73, Jim - N4ST

I have a KX3 that I have used the KX3 utility software with several times without issue. Today when I start the software there is no COM port to select. In the bottom left hand part of the KX3 PORT window is says Serial Port is Closed. (I’m using the Elecraft USB cable for the KX3). I can’t get it to work. I can control my Kx3 with DXLabs using the COM port no problem. I can use the Elecraft Frequency editor with no problem. I can use WinLink Express no problem. But when I start the KX3 utility software I can’t select a COM port – there are none listed. Here is my troubleshooting so far: 1. I know the COM port is there – it works for other software 2. I used the FTDI driver removal tool and uninstalled the FTDI drivers 3. I uninstalled the KX3 software 4. Reinstalled everything – but the issue remains Any ideas?
