I thought I saw the response that he got the firmware upgrade fixed by using the new K3 Utility. He had not upgraded the K3 Utility. I have the MKII and am curious if it works successfully. The last upgrade I did, I was at a friend's station, and he used a serial cable to the firmware upload.

This is discussed (briefly) in the K3 Utility Help, Troubleshooting section under "USB to Serial Adapter Troubleshooting". It's the last item on that page. The microHAM router acts as if it's talking to a K3 that understands just the documented K3 command structure. The microHAM router doesn't faithfully pass through data sent to or from the PC program. The firmware load process uses data streams that are not part of the K3 command structure. The K3 doesn't understand the K3 command set until its MCU firmware is loaded. You'll have to get the microHAM router out of the way so that it doesn't attempt to manipulate the data being sent to or from the K3 during firmware load. The most straightforward way to do that is to cable the PC directly to the radio with an RS-232 serial cable or a USB to Serial Adapter that doesn't change the data stream. The microHAM router has provided an "escape" string that supposedly gets the router out of the way so that programs like the K3 Utility can load through the router. It doesn't work at this point. The router seems to be confused by the sequence of commands the K3 Utility sends as it attempts to determine the K3's baud rate and firmware inventory. I'll continue to pursue this (I own a microHAM device), but at this point in time it just doesn't work.

Started the K3 Utility, V 1.1.6.3 and had it check the website for upgrade. This is from the K3 Utility log: 13:31:24 K3 Utility Version 1.1.6.3 13:34:18 Opening connection to ftp.elecraft.com 13:34:18 Connected to Elecraft server. Please be patient, this takes a few seconds. 13:34:24 Copying files to C:\Documents and Settings\Owner\Application Data\Elecraft\K3 Firmware 13:34:31 Copied hmcu0278.hex from Elecraft 13:34:35 Copied HDSP0198.HEX from Elecraft 13:34:40 Copied HAUX0198.HEX from Elecraft 13:34:43 Copied hfwnotes.rtf from Elecraft 13:34:45 Copied K3UtilityVersionInfo.txt from Elecraft 13:34:45 Copied 5 files from Elecraft to C:\Documents and Settings\Owner\Application Data\Elecraft\K3 Firmware 13:34:45 Ready 13:37:28 K3 failed to enter MCU firmware load mode 13:37:36 MCU programming failed. Verify file source and version. Turn the K3 off and back on, then re-try the firmware load. 13:37:42 Ready 13:42:31 K3 is not responding 13:42:31 K3 is not responding 13:42:33 Ready 13:43:57 K3 is not responding 13:43:57 K3 is not responding 13:43:59 Ready 13:49:50 K3 is not responding 13:49:54 K3 is not responding I tried turning on and off the rig, of course by having to kill the power supply and holding the Power switch on until MCU LD reappears...along with flashing TX led. I am using the microKeyer II as my interface and went to the K3 port (3) and clicked on the "disable router inquiries" before starting the upgrade process. I did save the previous config using the K3 utility but now the K3 is not responding to the com port so K3 utility is essentially dead... Help!
