[Elecraft] KDSP2

[Johnny Siu]

Hello Phil,
Very well respected and I did read similar favorable comments about KDSP2 like yours in the past. The best part of this mail listing is that we are used to agree to 'disagree'.
My K2 was gone some time and replaced by K3 and KX3.  Now, I am keeping a close eye on the Icom new IC7610 SDR which I saw in Tokyo ham fair 2016.

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.
