[Elecraft] K3 2803 Firmware Problem

[Glenn Haffly]

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
