Hi Don, Tnx for the advice. Rebooted the K3 and the PC. But what I had to do additionally was hit "Close Port" on the K3 Utility. Then hit "Test Communications". That set things straight for me to load the firmware. Not sure why that problem happened in the middle of an upload. But all is fine again.

The fact that the USB port is no longer detected points more to the computer than the K3. Re-boot the computer, and see if it detects the USB adapter - that has to happen first. Even if the USB port is internal to a K3S, the same thing applies, you must get the computer to recognize the USB adapter and assign a COM port to it. If the port is internal to the K3S, power cycling may help as well. Then follow the instructions to "Force a firmware load" in either the manual or in the K3 Utility Help file. 73, Don W3FPR 73, Don W3FPR On 1/28/2017 12:27 PM, N2TK, Tony wrote: > > Upgraded firmware from 5.54 to 5.56.
