[Elecraft] K3 Hardware Upgrades

[David Pratt]

Although I don't recall seeing anything about it on here, the latest 
KRX3 Errata Sheet C-6, dated 3 March 2009 refers to the cutting of two 
tracks on the main RF board to "ensure D-A converters always receive the 
proper signal level".

I have yet to do this mod on my K3.
