[Elecraft] New K3 built - can I reset the 5w calibration?

I learned the hard way that power handling capability of scope probes is 
frequency-dependent. I blew TWO of mine trying to measure 100w on 28 mHz. (no, one lesson 
is not enough for me). So check the ratings of your probes before you try this with more 
than QRP power!
