Good Morning/Day/Evening/Night,
While the numbers which Eric posted a few days ago are interesting, not to
mention very good... Congrats! ...I am still wondering about the 2100Hz and
1800Hz filter figures and the 2kHz numbers for 2700/2800Hz would also be rather
interesting, because they would
Toby,
I believe you have stumbled onto something that should be carefully
defined when testing with wide roofing filters when the DSP IF is set to
the more typical testing bandwidth of 500 Hz. The K3 has both IF shift
and narrow passbands available in DSP and they can be effectively used
Hallo Don,
I believe you have stumbled onto something that should be carefully

Stumble is the right word for it - I hadn't thought about this.
I would

Now that we have that out of the way - I would offer that I am very happy
thus far with the 400 hz CW filter. I have used it in 3 different contests
and my almost daily 160 meter weak
We're being conservative, too, hence the + signs in listings like the
one below. The average 5/10/20 kHz IMDDR3 from all the tests on narrow
filters comes out to around 104 dB, and we've seen 2 kHz numbers as
high as 98 dB. But Eric probably doesn't want me to mention that :)

Then you had better send Elecraft your new address so that you get your K3;-)
