[Elecraft] K3 FD report in high RF (K3 vs Flex 6xxx)

[Vic Rosenthal 4X6GP/K2VCO]

A couple of years ago I asked W1RFI at Visalia how come they would 
include a picture of a very sharp keying waveform and a spectrum display 
showing loud clicks or phase noise but not interpret it for the less 
technical types. He said that if you want that you should write to the 
editor of QST and tell him.

So that is what we should do about these issues.
