[Elecraft] K2#3363

Y I K E S!!! Paul, my display too slipped about that much and now I have the 
top horizontal bar in view....I've decided to live with it fer now cuz it 
doesn't affect the operation. If I ever decide to sell the K2 (probably 
not.....) I'll deal with the display slip then....Thank goodness I'm not the 
only one who has done it. Gary at elecraft thought I was crazy when I tried 
explaining to him my screwup (one of many!)....73...SN 3345
