[Elecraft] K3 always 100 W

[Pedro, EA4KD]

Thank you very much Don;

I have been testing and when do a tune the power is always 100 w although I have it set to 15 w in the TUN PWR menu., always 100 w.

In normal operation, cw or ssb, I can choose the power between 0 and 100 w without problem.

I will start checking the wattmeter.

Thank you very much for your help.

Pedro,

If it were a K2, I could tell you that the diodes in the wattmeter have 
been damaged and need to be replaced.  Those symptoms are almost the same.

The K3 controls power in a similar manner, and I would suggest you start 
with the wattmeter - I believe it is on the KAT3 board in the K3.
