[Elecraft] K3 Problem: Blank display Won't turn OFF
Need help with my K3 S/N 280. While loading new firmware into the KPA500, something happened to my K3. The firmware load to the KPA500 appears to have succeeded, but now the K3 is ON with a blank display, the K3 won’t turn OFF and the K3 Utility says that “COM3 is being used by another application”. It looks like I’ve lost my K3 firmware and cannot access the K3 in any way. Wow, what a mess! I tried turning things OFF and , then, ON again to no avail. What happened? And what can I do to get the K3 to identify itself and work again.

Re: [Elecraft] K3 Problem: Blank display Won't turn OFF
Roger, Do you have a KAT500? It must be ON before booting the K3. Does it say MCU LD on the display (may be unlit, use a flashlight)? Then reload the firmware. The COM3 busy may (probably does) require a reboot of the computer. Try disconnecting the serial port. Since the computer hung that port out to dry, it may be toggling something that denies the K3 the ability to boot. 73, Rick wa6nhc -Original Message- From: K8RS While loading new firmware into the KPA500, something happened to my K3.

Re: [Elecraft] K3 Problem: Blank display Won't turn OFF
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.
