Bill, it should not fault. When the KAT500 it is tuning, do you see on the KPA500 amplifier front panel the asterisk change to an underscore? If the asterisk stays visible, the amplifier is not being inhibited for some reason.
What is the SWR reported by the KAT500 after tuning? If it is not low enough, the KPA500 logic may trigger a fault due to excessive reflected power. Do you have the latest firmware in both the KAT500 and KPA500? IIRC, there was some tinkering with the timing of the functions that may have been to avoid spurious faults. I recommend making sure you are running the latest. 73 Ron AC7AC -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Bill Wiehe Sent: Saturday, March 16, 2013 7:31 PM To: elecraft@mailman.qth.net Subject: [Elecraft] K3, KPA500, KAT500 interactiions I must be having a senior moment so bear with me. If the KPA500 is "not keyed" (K6KR) and/or it is "inhibited" (AC7AC) while the KAT500 is tuning, why am I getting a "fault" that requires a manual reset? BTW I am using the cabling as described in figure 1 on page 4 in the KAT500 owners manual with the correct DB15 cables and, in the interest of full disclosure, I do use the KPAK3AUX Y cable at the K3 ACC port.
