[Elecraft] K3: Problem Solved with K3 S/N 280

[K8RS]

Group,
             Problem Solved!  Many thanks for all the suggestions.  It turns out that the issue was much more simple than I imagined.  I had no power t going to the KAT500.  We  had Severe Thunderstorm Warnings on Tuesday and I unplugged everything.  Did not notice that the KAT500 was still without power when I started downloading the firmware to the KPA500.  The result:  The K3 wouldn’t turn ON properly when I tried to get on the air.  Plugging the power plug back into the KAT500 rectified the issue.  All is well with K3 S/N 280!  The KPA500 has its new firmware. Thanks again for the help.
