No power out

[Elecraft mailing list]

I was doing FT8 and had made a few as when I suddenly had no power out. Did the basic trouble shooting with a dummy load.  Still no power out. Called Elecraft and they said that the low power amp was out. Did some on line research and found that when tuning up the external ant tuner at 5 watts it stresses the low power amp and they fail. Recommend that you tune up at 3 watts or less to keep from burning out the low power amp. By the way I did some online research and found this is a common failure with the k3.Sent via the Samsung Galaxy S8+, an AT&T 5G Evolution capable smartphone
