[Elecraft] KPA500 suddenly low output - only 30 watts

[mike]

No, the asterisk on the KPA is missing. Nothing appears on the left of the
KPA LCD. I understand that to mean the KPA is not receiving a valid PA KEY
signal. I am using Elecrfat supplied AUX cables from the K3 to the KAT500
and another one from the KAT500 to the KPA.

I did recently change my antennas to the KAT500, removing the one that I had
going to terminal 3. So in case there was a problem with the KAT500,  I just
tested going from the KPA RF output directly to an antenna (removing the
KAT500 from the circuit.) I also changed the AUX cable to go from the K3
directly to the KPA instead of going from the K3 to the KAT500 to the KPA as
it is normally wired here. No change noted.  73 ..mike AI6II
