Hello Group, I'm running KPA500 #1076 with firmware 1.23 installed. It's connected to my K3 via the elecraft AUX cable and is connected to my PC via serial to USB adapter cable using FTDI chipset. Interfacing functions with the PC and K3 work flawlessly.
It runs perfectly apart from one intermittent peculiarity: unpredictably, when in QSO, the amp will switch from operate to standby mode. This does not trigger the Fault indicator and no fault # is ever reported by the KPA500 to the utility program or to the K3 LCD. It can't identify any triggers for these auto-tripping events. I simply return the KPA500 to operate mode and continue the QSO normally. This occurs on average once per hour of operation, rarely more frequently. Any ideas where to look for the cause? Thanks and 73, John VK7JB ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
