ERR PTT means that the PTT line was being held low as the K3 is starting up. This sounds more like a poorly done connector (short), or a bit of that tiny wire used in a shield shoved back in a male connector. Betting odds are on the side of a physical problem with cords/connectors.
[see http://www.elecraft.com/manual/K3%20Owner's%20man%20D9sm.pdf page 69] It could also be a problem with the output transistor in the KPA500. This would NOT indicate RFI because the K3 will no longer key up while booting itself. BTW, a local copy of manual PDF is a great time-saver, as Adobe Reader will search text and diagrams in Elecraft manuals, including all the error messages. Becoming familiar with the schematics is a great help as well. 73, Guy.
