[Elecraft] 700 Hz roofing filters

[Rick Dettinger]

Hi Don,

I agree.  That is why I bought a 1 Khz filter when I got my K3 in  
2008.  I just use the DSP set between 500 and 1000 Hz.  My CW  
operating is about the same as yours.  If I need to use a sharper  
filter than that, it is likely due to QRN rather than QRM, and the DSP  
works fine for that.  Including the NR section.  I don't close the  
blinds unless I need to!

73,
