[Elecraft] KXUSB

[Don Wilhelm]

Paul,

Is the FTDI adapter identifying as a COM port when it is plugged in?  
You can check using Device Manager - open Ports and unplug the adapter - 
which COM port goes away?  Then plug it back in and observe which COM 
port is assigned.

Windows no longer adds the FTDI drivers, you must download them from the 
FTDI website.

Double check your homebrew KXSER cable.  Did you get the RXD and TXD 
connections right?

All in all, it should work quite nicely.
