Wayne, of course, is talking about the analog (hardware) noise blanker. 
  There is also a DSP noise blanker which we *do* have, and by itself it 
has been as useful to me as the noise blanker in my K2 and better than 
the one in my TS850s. It is also much less affected by other in-band 
signals.

Add to this some special AGC functionality (an AGC loop within a loop 
with a very short time constant called AGC2) for dealing with noise 
spikes that might trigger AGC, and you are really looking at *three* 
lines of defense against noise.

One more thing, which I am finding useful in my noisy location, is the 
"transverter interface" accessory, which might really be called 
"low-level receive/transmit RF interface". This provides a convenient 
insertion point for an MFJ or other RF noise canceller, without the need 
to worry about t/r switching.

Of all of the features of the K3, I think that the anti-noise 
functionality will make the most difference in improving my DXing here 
in my noisy location.
