[Elecraft] Updated K2?

[Don Wilhelm]

Just a quick note on using the KDSP2 filtering --
For best overall operating (especially in crowded band conditions), it 
is always better to use XFIL to narrow the IF filter first, then use 
AFIL to add the KDSP2 filtering if necessary.

That keeps the level of strong adjacent signals to a minimum and 
prevents overload of the AGC (and the resulting receiver de-sense).

I do see several operators who use only the DSP filtering, leaving the 
preceding IF bandwidth 'wide open' - not the best way when the bands are 
crowded.
