[Elecraft] K2 purchase question

[Don Wilhelm]

  Bud,

The IF filters on the K2 are quite adequate for most purposes.
The KDSP2 adds audio DSP filtering which has very steep sided filters, 
and has noise reduction capabilities as well which may be a help in some 
situations.  The normal FL1 position is a Low Pass filter which kills 
some of the high frequency hiss in the audio.
An alternative would be the KAF2 which provides a peak response active 
filter and a low pass filter that is in-line all the time.

Actually, it is easy to add the KDSP2 or KAF2 later, so if you are 
wondering whether the normal K2 IF filters will be adequate for your 
needs, just try the K2 without the audio filtering for a while and then 
decide if you want to add it.

73,
