[Elecraft] K3 Build comments

[Mike Penkas]

I just finished my build on #106 and everything working fb except of course the NR with ver 1.42. 
One comment I might make is to temporarily screw down the 3 low power final transistors on the bottom of the RF board during construction.  They kept catching on my ESD mat and twisting around during construction.
