[Elecraft] Benefits of Buying a Factory Assembled KX3

[Don Wilhelm]

Fred,

My understanding --
The roofing filters are at baseband (audible frequencies), but are 
inserted prior to the conversion to digital - that means the DSP will 
not see content outside the roofing filter range and the possibility of 
overload in the A to D conversion is greatly reduced.
