Did you have the KIO3B board installed during the repair so you have an 8P8C connector (sometimes called an RJ-45) on the rear panel? If so, you MUST use the 8P8C and an RS232 port on the computer to reinstall following a failed load.
On the front of the KIO3B main board, near the speaker cable connector, is a toggle switch. Remove the K3 top cover and place the USB <-> USB/RS232 switch in the USB position. You should have received a suitable interface cable with the upgrade but you'll need an RS232 adaptor if you don't have an RS232 port your computer. Be sure to return the switch to the USB position after completing the firmware upload. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Mike Murray Sent: Sunday, September 11, 2016 10:16 AM To: Rick Bates (WA6NHC); elecraft@mailman.qth.net Subject: Re: [Elecraft] K3 appears to be bricked Thanks for the suggestions so far - tried each several times but the K3 is still toast.....

All you have to do is turn everything off including the computer. To turn off the the K-3 you have to remove the power connection. Next, turn on the computer. After the computer boots up, connect the power to the K-3 and turn it on. You will see the same MCU LD message and blinking transmit light, but the computer utility program should be able to find the K-3 and reload the firmware. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to r...@elecraft.com ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
