[Elecraft] K3 Synthesizer Stiffener Plate Mod

[Edward R. Cole]

I have not detected birdies in the K3, but have not used it a 28-MHz 
so far.  Until I have a VHF transverter I will not be able to examine 
this very well, but I will be using 28-MHz as an IF for both 144 and 1296 MHz.

But is the stiffener standard on radios after spring-2010?  My K3 is 
#4043.  I can see that additional ground plane surrounding the synth 
may reduce susceptibility to birdies internally generated in the K3.
