As others have noted, the K3 is not like older radios -- it gets its IF 
selectivity from DSP. You can set it anywhere you want. The plug-in 
filters are roofing filters -- they protect the DSP from getting blown 
away by big signals close to your frequency. You need them in contests 
and in DX pileups, but that's all. I use narrow CW filters like K2AV 
described for contesting. For everything else, the IF filtering provided 
by DSP is all you need.
