I could take offense at that statement. We each speak from our level of
education and information available.
I thought we had a technical forum here - there are some asides

If it pleases you to use DSP set wider than roofing filter - by
all means, go for it.

Igor,
You are missing the point. K8ZOA's measurements were for a
continuous carrier. You can't measure speech intelligibility with
the K3's dBV meter.
My recommendation for DSP bandwidth of 2.1 KHz and 1.8

Ah but Igor, you are trying to argue from evidence. That's a no-no.
The way to prove your point is to assert it in CAPS. Then and only
then will you be

Exactly right.

2.8, 2.1, 400 - no need to go tighter IMO. Before buying a 1.8, I suggest
spending time on someone's K3 with a 1.8 if you can. I think you would find it
fatiguing to listen to for more than a few minutes. Certainly not a rag chewing
filter.

Dave,
1.
I prefer the 2.1 filter for SSB, 1.8 can potentially give a slight edge
when the bands are extremely crowded, but generally speaking I use the 2.7
and narrow down to 2.1 if there is much QRM, remember that with the DSP you
can go as low as you want, so it only makes a real difference if
*Jack,
with respect I would disagree with your assessment of the 1.8Khz filter.
From experience, I had both the 2.1 and 1.8 fitted and by judicious use of
the Hi Cut/Lo Cut adjustment I find the 1.8 far better in practice.
Audio quality is easily made pleasant to the ear without introduction of
I used the 1.8 for the entire WPX SSB contest, with a DSP width
of 2.1 KHz. It sounded great. I never messed with any of the
settings for the entire contest. To get this combination of
DSP=2.1 and crystal=1.8, one has to install the 1.8 filter as if
it were a 2.1, so it switches in at

Not at all true. When reading K6LL's comments, bear in mind that he is
a VERY good operator and engineer. I value anything he has to say.

paper on the matter somewhere on Elecraft web site (by Eric S).

I am still studying the K3 and the various options I use. I still plan to
purchase one.
My previous radios (IC-756PRO the last one) I used 2.4 khz and 1.8 kHz for SSB
and 500 hz 250 hz for CW / Data.
The K3 comes with a 2.7 kHz 5-pole filter.
