Rob,
Did you set the CONFIG: RS232 to USB? You should then be able to get
K3Utility to communicate with the K3 over USB.
Once you accomplish that, you should be able to download the new
firmware through the USB port.
If that does not work, set the switch on the back of the board to the
RS-232 position and connect the PC (with a USB to serial adapter) to the
dongle provided with the upgrade kit - be sure to set the RS-232 menu
parameter back to 38400 to use RS-232.
I recall that firmware 4.86 is before the memory slots for the TX Gain
data was moved, so be sure to run TX Gain Calibration after the firmware
upgrade.
73,

I just completed the install of the KI03 update to my K3 SN 4843 and guess
what? I forgot to update the firmware to the latest version (4.86 now). The PC
won’t talk to the K3 through the USB! Do I need to restore the old boards and
then update? I am watching for your HELP!
Rob, KJ6ILO
