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
