[Elecraft] Firmware Failure - Update

[James D. (Jimmy) Walker, Jr.]

I’m getting some interesting responses to my question about firmware failure. Thanks to everyone who has replied directly. To update my post, I always turn the rig off using the power switch. I never turn off the power supply to the rig. There is always power available at the power input. When the MCU LD failure occurs, it’s always at the power on, startup time, after the rig has been idle for a week or two. If the rig will power on correctly, it will not fail during operation. 

Does the EEPROM unplug to make replacement easier?
