During the ongoing All Asia Contest, after a few hours of sleep, I started to call Cq on 20m using my Acom 1000+ K3 at 50 W. After about 20 minutes I noticed ERR 12Volt and the power went down to 5 W so I switched off the K3 and power supply. After some 15 minutes of thinking I restarted the power supply and the K3. I worked some stations and called CQ for abaut 15 minutes. Then again I got the ERR 12V message and K3 switched to 5 W. After more thinking and reading the Manuel, I decided to try again but this time monitor the supply voltage, current drain and PA temp. I am using a regulated DC Power supply rated 13.8V and 30A. During this 10 min I operated barefoot with K3, power at 100W. Power supply voltage steady on 13.9V. Current drain on listning at 0.94A. Current drain on voice(SSB): 2 - 15A PA-temp: 38-40 degreesC As the power supply seems to do its job OK I wonder if something is intermittently wrong with the K3 PA?? Any suggestions would be appreciated!!
