[Elecraft] KAT500 EEPROM Problem

[Ed]

 No I didn't try to reload the firmware.  I was afraid that if the EEPROM was damaged, a firmware update might not be successful, and leave me with an inoperative (bricked) KAT500.  According to their web page, Elecraft is not servicing KAT500's due to COVID-19 limited operations.  Currently, our KAT500 seems to be working with the other two antennas, so I am waiting to hear from Elecraft regarding the next steps to take.Thanks & 73,EdN2BHD

 You mention that you ran the "KAT500 Configuration Software" 
but you didn't say that you tried to reload the firmware. 
Have you tried to RELOAD the firmware? If you didn't reload 
the firmware, then I would suggest that you give that a try.

Yesterday I was using the K3 on 6 meters with ANT 1 and ANT2, which were not designed for 6 meters.  The KAT500 was able to tune for a low SWR, and the TX power was about 50 Watts.  No problems occurred during the 6m net, but after the session was over, I noticed that I could no longer select ANT 3 on the KAT500, regardless of the band.

I repeated the process a few times, and the same error occurred each time.The KAT500 firmware is at v1.75.  I suspect that RF may have gotten into the KAT500 and corrupted the EEPROM.  I'm not sure what to do next.  Has anyone encountered a similar problem?
