Good Evening,
While I am running the nets I think I may miss someone if I run closed
down. I normally use a setting of 1.0 kHz and go to 1.8 kHz if I am
seeking off frequency. I have an Icom with a 250 Hz filter and it sounds
odd to me. How would I know if there is someone right next door calling
me? I'd much rather hear the babble of others than miss someone calling
me.
One time I was recording my contact with a friend to see how poorly I
was sending. I knew I was ignoring another operator nearby. When I
rewound the tape and played it back I copied five different stations. I
had ignored four of them without realizing it. I guess they just weren't
calling me so my mind tuned them out.
While I do have my K2 set up with 1.8, 1.0, 0.5, and 0.25 kHz filter
settings I rarely use the third and fourth settings. Missing someone is
not what I intend to do. Good grief, they may teach me something!

I can't speak about the 718 or the Elecraft DSP, but in my experience
such
"brick wall" filtering creates far more problems than solutions. A huge
amount of unwanted stuff is produced by signals on the sharp edges of
such a
filter that appear throughout the passband - much of it is that 'noise'
you
mention.
I work 99% CW and my K2 is seldom set for less than 1.0 kHz bandwidth. My
minimum is 0.4 kHz used only when I get a "loudmouth" shouting from
almost
on top of the signal I'm copying. That occasionally happens during a
contest, but that's about it.
I do have a skill that a great many experienced CW ops have that might be
the difference. We can copy easily with several signals within the
passband.
It's like listening to one voice in a crowded party; we just "tune out"
the
other babble going on around us unless it's something we want to follow.
It
only gets difficult if one nut starts shouting in my ear when I'm trying
to
listen to someone else, Hi!

Hello
I haven't had my K2 (# 5846 ) long enought to fully understand all the
different settings that are possible with it , so I have a question. My
CW
filter setting are FL-1 1.50, FL-2 0.70, FL-3 0.40, and
FL-4 is 0.10. Even FL-4 is no where near as effective as the 250 hz
crystal
filter in my Icom 718. When I turn on the 250 hz filter in the Icom, it's
like building a wall right on each side of the signal that I am listening
to. Nothing else is heard except noise and signals that are exactly on
the
same frequency. Is this kind of selectivity possible with the K2? If I
installed the DSP option would that help? And if so, what would the
filter
settngs need to be? The only options I presently have are the 160 meter
option, noise blanker, serial adapter, ssb option, and the KPA100. Thanks
