I'm in the ARRL CW contest this weekend and the KPA1500 has been working fine. However, a few minutes ago I noticed I was getting about half the output power on 20 meters that I typically get with around 30 watts drive (about 600w vs 1200w). PA current is less than normal, around 30a. Similar problem on the higher bands, I can no longer get 1000w. On 40m I can, but it requires more drive.
Seems like something died in the amp; I'm not familiar with the design, but perhaps an output module. No errors or ill behavior from the amp other than the loss of power. I will contact Elecraft support unless there is something I'm missing here. I just looked in the archive and see that this has happened to others.... I use the amp remotely so I guess I'll have to take it home with me.
