[Elecraft] K3/100 kit

[Guy Olinger, K2AV]

A friend of mine put a mag mount on top of his 2m base radio.  Never worked 
right after that.  Never able to realign it.  Warnings below should be 
heeded.  A good new (not worn) phillips screwdriver will grip a screw enough 
to get it started.  I bought a brand new Stanley set for my K3 assembly, and 
went through my old ones and threw worn ones out.

73, Guy.
