[Elecraft] K3 Suddenly Putting Out Only 25 watts at 100 watts indicated

[Rick WA6NHC]

Make sure the dummy load is connected; the cable is 'good'; that you are 
not routing the serial data via the P3 (as if you were updating 
firmware; there is sometimes a slight stumble in communications 
otherwise) and that your supply is giving appropriate voltages under load.

Try this a few times, it sometimes needs that to pass.  Once it passes, 
save that config, then make sure it passes again.  And again until 
you're satisfied.

Then check the power out at 100W.

Failing that, time to call support.
