I hadn't used my K3 (#474) for a few days when I checked into the Elecraft SSB net on Sunday. I immediately noticed that the Power Out bar graph was peaking only around 60-70W. It normally peaked closer to full output on voice peaks. Later I checked it with CW and it was still only hitting about 75% output. I confirmed the power control was set to 100W. I did an Auto tune before each test and this problem exists on every band. Both my LP-100 and my LP-100A digital watt meters showed about 120W output (both were factory calibrated by Larry). But the K3 bar graph still shows 25% lower than full output. This I also confirmed into a dummy load. I had not observed this before Sunday. All else appears to be functioning properly. I might be one or two software versions behind but have done all circuit upgrades. Is this a known indication of an upcoming problem, or do I simply need to recalibrate the K3's Power Out meter? 73, Terry W0FM ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net
