I wanted to note the KPA500 is on a 220v AC line. I did try backing off the K3 to FW 4.83 and also reloaded 1.38 in the KPA500 with no change in results. In running though the KPA500 menu, I noticed that the INHIB IN was set to ENABLE, which according to the manual means ...
"ENABLE allows the amplifier operation to be inhibited (won’t amplify) when a logic low is applied to pin 11 of the AUX Connector (see pg 26). When amplification is inhibited, an underscore instead of the asterisk appears on the left end of the LCD display." But this is not what I experienced (unless I don't understand what is being said.) The asterisk was always there (not an underline) whether or not it was set to ENABLE or DISABLE. In fact, going back and restoring from earlier saved configurations I found the setting had been ENABLED since January of this year. So apparently that doesn't work when using the K3 and Elecraft AUX cable. Interesting.... I do now have it set to DISABLE, but as I said not no avail. ..mike AI^II -- View this message in context: http://elecraft.365791.n2.nabble.com/KPA500-suddenly-will-not-provide-amplified-output-tp7591188p7591190.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
