This afternoon I tried to upgrade the firmware and got a problen.
Now the K3 TX LED is blinking and the LCD display shows MCU LD Referring to the handbook It says I should reload the firmware....... My computers tells me the K3 is not responding and wont upload the new firmware. Forcing a firmware Download: tried unplugging hte power from the K3 as suggested for 10 seconds, held the POWER switch for 10 seconds TX LED is now flashing as above and I still have MCU LD on the LCD Display and the computer STILL tells me the K3 is not res[ponding.......Where do I go from here?

Do you have a direct connection between your computer and the K3? Not
through something like a microHAM controller, right? I test this all the time. It's usually a cabling problem between the PC and the K3. Please use the K3 Utility's Port Tab "test communications" button or restart the K3 Utility (both cause the K3 Utility to try communications at all baud rates). The K3 in its "boot loader" state (which is indicated by the red Tx LED and "MCU LD" in the display (which may not be lit) will communicate at only 38,400 bps. The K3 Utility's Test Communications button should detect that the K3 is at this baud rate and show a "warning" (exclamation point) dialog box with that baud rate in it. It might help to beg or borrow a different RS-232 cable. These problems are frightening, but are most often due to a straightforward cabling problem.

Thanks for the follow-up response, Tom. Problems like this can give one a
sinking feeling... Very glad you're QRV now. I'm getting ready for Sweepstakes now, our club's big domestic contest of the year. I'm in Nevada. 73 de Dick, K6KR -----Original Message----- From: Tom Wylie [mailto:[hidden email]] Sent: Saturday, November 01, 2008 10:39 AM To: Dick Dievendorff Subject: Re: [Elecraft] Help! Absolutely correct DIck - appears to have been a faulty serial cable - my first ever. Cold sweat now over hihi K3 singing merrily.....
