[Elecraft] Why all those filters - K3

More importantly, that the full specs are released. Factors such as 
group delay can be very important when judging a filter for a purpose.

Why so many filters - in very loose terms, to "protect" everything 
after filter and not let more reach the back end than necessary. You 
do not want the ADC overloading or the AGC reacting to signals which 
you can not hear.

I am glad that Elecraft is offering a large range of filters, which 
should allow one to tailor the radio to needs and budget. I am holding 
back on the filters until I know more. Which filters and how many 
really depends on your use of the radio. For some, 200Hz/250Hz filters 
will be very important (40m in EU especially during contests) and for 
others senseless overkill. I will likely end up with a whole 
collection of filters in my K3, and am very very curious about the 
variable bandwidth filters.
