To put your K3 back into a usable state: 0. Kill the KPA500 utility program. This should leave your COM3 free for the K3 utility. If it doesn't then reboot the computer.
1. Remove the K3 power and leave it disconnected for 15 seconds or so. 2. Re-connect K3 power and hold the K3's power switch down for 10 seconds, then release (might take a little longer). To be sure the K3 is in a force-load state, look at the display. It should have the backlight off and MCU LD showing. 3. The K3 is in a "force-load" mode now. Bring up your utility and reload firmware. Best to contact Elecraft support so that they can help figure out what happened. 73, matt W6NIA On Thu, 30 May 2013 16:06:46 -0400, you wrote: >Need help with my K3 S/N 280. > >While loading new firmware into the KPA500, something happened to my K3.
