[Elecraft] Windows 10 Update Breaks COM Port for K3 & P3 Utilities

[Don Wilhelm]

Mark,

Are you using the USB interface on the K3S, or a USB to serial adapter 
to connect to the K3?

If that is the case, did the assigned COM port get changed with the 
Windows 10 Update?  Some have reported it has happened to them.

To check the COM port that is assigned, open Device Manager and expand 
the PORTS listing.  Then unplug the USB connector and see which COM port 
goes away - now plug it back in and observe which COM port is assigned.

Plug that COM port into K3 Utility or any other application that you are 
using to communicate with the K3.

If you don't see a COM port assigned, then suspect the USB to serial 
adapter - reload its drivers to see if that fixes it.

73,
Don W3FPR
