Eric I wonder if you have a serial/usb-serial link from your K3 to a computer? If you have may I suggest the following:-
1. Make sure you have the latest version of the K3 Utility program. 2. Make sure you have the latest release of the K3 Firmware. 3. Save your present K3 Configuration to the computer. If that works, then switch on your K3 while holding in the "Norm" control until you see "init" on the display. 4. Now press and hold the Menu button until you see the "CONFIG:---" on the display. If that works then there may have been some corruption in you config settings. Try then to save back to the K3 your saved configuration. If having done that and holding the menu button no longer gets you into the cnfiguration menu, you will have to reset the K3 as above and manually re-configure all of your settings. 5. If the reset doesn't work then keeping the K3 attached to the computer, press and hold the power button for approx 10 secs. You should then see on the bottom left of the display "MCU LOAD". Run the K3 utiliy program to download the latest firmware into the K3. That should fix the problem. I do hope that helps. Sorry it's such a long winded explanation. 73's Jennifer EI7GCB1: I do
2: I had 2.78 which worked fine displaying some vanity banner on startup and wanted to upgrade to 2.8
3: After installing 2.78 a few weeks ago I did
4: Pressing, tapping, holding, nothing can persuade my K3 to go in config mode, tried initializing again holding shift/lo/norm together with power on to no avail.
5: K3 goes to MCU load mode, but utility still can't communicate
Since I normally use this Prolific USB->serial thingy which caused some problems in the past I even made a RS232 cable to hard-wire K3 and PC.
Even this doesn't work, so I'm starting to think there's more to it then i had hoped for.....
Thanks
