[Elecraft] KDSP2

[Phil Wheeler]

Au Contraire in my case, Johnny.  I've found the 
KDSP2 to be very effective and still use my K2/100 
in my secondary operating location as my QRO rig.

The issue with the KDSP2 is getting the settings 
right. That was tricky and probably took me a year 
or two of experimentation. But now it works very 
well for me and I find the NR very effective.

While there are a number of settings in KDSP2 which you can manipulate, regrettably none of the settings gave me a present result.  The artifacts from the DeNoiser is huge and much worse than K3.
