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.

Our club K3 is connected to a KAT500, which is connected to 3 antennas (ANT1:
Zero-Five vertical, ANT2: DXCC fan dipole, ANT3: 135ft doublet. 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 ran the KAT500 Configuration Software, and verified that ANT 3 is configured for use on
all bands but 6m. The configuration SW "Operation" tab could not select ANT3
either (the K3 was turned off).
I tried to save the current KAT500 configuration, but a "Save Configuration Error" box
popped up after about 10 seconds, which stated "No response to Read EEPROM block". 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?
Thanks & 73,EdN2BHD
