Hi Fred, That is exactly what happens when I plug in or remove the USB cable. Narrowed down the problem to the KIO3B Main Board. Ordered a replacement board. 73, N2TK, Tony

You should see a new COM port come up. That's the port you use to talk to the radio. It's faintly possible you are missing or have an old driver, but Windows almost always installs the correct driver transparently when you plug in the cable. Unplugging the cable will cause that port to disappear. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 5/24/2018 3:49 PM, N2TK, Tony wrote: > Hooked up my backup K3 so I could add a mod on the other K3.
