K3 2803 Firmware Problem

[ghaffly]

Good morning all , I have a problem with firmware upload to my K3. All I can
load is MCU. The FBF fails at load address x0040.
I have used two different computers using both a 9 pin straight through and
the KUSB. I have the latest K3 utility.
When loading from a past configuration I receive an error message Verify
Failed at EEPROM address 131.224
I have corresponded with Gary at Elecraft several times and did check those
items he suggested. As of yet , Gary's suggestion have not worked.
I have yet to get a full firmware download. Does anyone have suggestions for
me to check or does the radio have a problem and need to go
back for repair at Elecraft?

Thank you
Glenn

Glenn,

This may sound strange but I had a similar problem about a month or so ago on my K3, Serial #386.  I tried everything and was convinced that the K3 was headed to Aptos.  Conversations with Gary did not help either.  In frustration, I shut the rig down.  I came back the next morning and thought I would give it one more try.  To my utter amazement, I was able to reload the firmware successfully and as it was reloading, I could hear my K3 coming back to life.  After the firmware reload, everything was fine.  I contacted Gary and he said it could have been due to an overheating condition in the Front Panel and, that letting the K3 cool down completely was the cure.

I have had no similar problems since then.
