[Elecraft] Firmware Failure

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

I wrote a few months ago about the strange occurrence of finding my firmware missing or corrupted on my K-3. In it’s state of failure it displays MCU LD on a dark screen. The Transmit light blinks on and off. My computer cannot detect the K-3 to reload the firmware. The problem has occurred several times. The solution, inconvenient but workable, is to disconnect the P-3 and hook the computer up directly to the K-3. In doing so, I can reload the firmware. My question is, “Why does my K-3 lose it’s mind?” Is there some battery that backs up the firmware? Could such a battery be dead as happens sometimes in older computers? This is very inconvenient. Help please.
