[Elecraft] K3 noise blanker test

[wa9fvp]

Using an Agilent  DSOX3024 oscilloscope, with a built-in function generator, 
The generator was set for 200mv amplitude and the pulse width was adjusted
for minimum interference at each NB setting.  The generator was connected to
the K3's RX-IN port.   

On some settings and pulse widths the noise was completely eliminated while
other settings yield an almost inaudible "click" in the speaker.
