Johnny,
Here are the KDSP2 settings I am using. I'm sure they are not optimum but I
am happy with the performance I get. There is quite a bit of QRM here on 80m
SSB and the KDSP2 suppresses most of it so the voice is readable.
nr 94 10
nt 40 07
Sn G 5.0
SF G 7.0
I don't have 80m transmit capability but I like to listen sometimes to the
Canadian traffic nets. I use a little indoor vertical from MFJ and they are
very strong signals here in northern Washington. I usually have the KDSP2
agressiveness set at nr2 or nr3 and the voice is usually intelligible.
Sometimes the QRM is very low and I don't turn on the DSP. I suspect there
are no really perfect settings since each signal being received has its own
characteristics.

Subject: RE: [Elecraft] KDSP2 - artifact
Johnny,
I suggest that you search the archive for threads on this subject.
The KDSP2 seems to suffer from more aggressive artifacts on SSB than other
DSP
filters such as the BHI.
Some people say they have cracked it, others (like me) have given up....

Johnny,
I can't give you a good answer because I don't use the KDSP2 myself.
Perhaps someone else can give you some pointers.

Thanks for your advice in the past. I used K2 in the CQ WW SSb contest.
When I engaged the KDSP2, I found that there was too much artifact under
SSB mode. I would be grateful if you could advise how I can adjust the
parameters to lessen the artifact. I notice there are two
parameter namely
Beta and Decay time. Which one should I adjust?
Thanks a million,
Johnny Siu VR2XMC
