[Elecraft] DSP impressions

[Andy Bullington]

After using the KDSP2 for a couple weeks (CW only) these are my =
impressions.  I love the sound of the filters and the degree to which =
noise is softened or eliminated. They are easy to use and easy to listen =
to. When used in conjunction with the xtal filters, nearby QRM can be =
virtually eliminated. This is what I was hoping for when I bought the =
KDSP2 and I haven't been dissapointed.=20
   For CW I don't personally like the NR function. The distortion added =
to the incoming CW signal is more bothersome than the noise it =
eliminates,
for me. I have tried all possible settings of the NR with CW but I've =
settled on OFF.=20
   The K2 has close to perfect QSK and the slight scratchy quality from =
the DSP is at first annoying but it is really very slight and I've grown =
used to it. I realize there is a mod for it but it doesn't bother me =
enough to, at this point, take my new K2/100 apart and start messing =
around.
   I DO wish there was a 1 button ON/Bypass function for the DSP. That =
would definitely be assigned to PF1 or PF2 if it were possible but it =
seems it is not. As it stands, its several button pushes to get to the =
On/Bypass function.
   I still haven't gotten good at selecting the DSP filter I want. I =
invariably
tap instead of hold at some point and end up having to cycle through all =
the xtal filters to get back to where I want to be.
   Bottom line is I like the KDSP2 very much and its a great addition to =
a great radio.
