[Elecraft] KX3 Question

Sun Oct 14 06:25:01 EDT 2012

I stil think that the owner's manual is telling us to do the 
calibration, and the kit assembly manual is telling us not to. As I'm 
lazy, and the kit assembly manual is more recent, I chose to not 
calibrate.  But I think there should be an erratum to the owner's manual 
about this.
