[Elecraft] Tuning the ATU on the K2

Pretty much a drea. It's almost (if not) impossible to get '000'.

I used an analog voltmeter with a very low voltage scale. You could do the 
same thing with a DMM which has an analog scale as well.

Generally, if using the LCD readout, anything 10 or less is acceptable.
