Brian,
I use NaP3 with my KX3. It is set up to fully function with the KX3, ala the
FlexRado series. I can either control my KX3 with NaP3 or just reflect what I'm
doing with the radio, and the monitor than functions like a panadapter. As far
as I can see, NaP3 is the only software package that

Hello Stan.
I am an avid CW enthusiast and spend 100% of my time, usually around 4-6
hours a night on 20/40m CW. I have 2 identical loaded to the the max
K3/100's and P3's purchased late this year. I have been very happy with my
filter choices:
1. 13KHz FM
2. 6KHz AM INRAD
3. 2.8KHz INRAD
4. 400H
*Al,
whilst your statements hold true for you, I DO use the 1.8Khz almost as my
default. Attention paid to Hi/Lo gives me nice intelligibility and if you

behavior of stations deliberately providing QRM on their call frequency yo

Don,
That is good information for prospective kit builders. Yes, the
Elecraft instructions are very good - follow the instructions given in
the manual and you will have success.

Joe,
Understood. I wanted to be able to simultaneously hear and see 12 Khz or
so of cw signals, thinking that I could more quickly identify the
station being worked. For example, if I know the dx station is listening
from 14.010 to 14.020 (admittedly pretty wide), I figured I could

Another way of looking at it is this:
Just because a signal gets inside of your roofing filter doesn't mean squat. If
the mixers can handle the signal's level, and the HI LO cut controls can slice
off the signal, you won't even know it's there. You simply don't care!

Thanks Jack the eevblog was very helpful. Exactly the kind of info I was
looking for. I appears the USB scopes are somewhat lacking in the
samples/sec dept. Looks like I'm going with a deskstop, 100mHz, 1 GSa/s, 2
channel.
Thanks for all the comments everybody.

Right, Don!
I still believe that many K3 users are under the erroneous impression that the
roofing filter determines the receiver bandwidth. It does not. The HI and LO
knobs do.
The only thing the roofing filter does is determine the MAXIMUM possible
bandwidth of the receiver.
In 99% of case
Joe,
Good observations, all. I agree that 4.2 KHz is certainly good enough
for communications audio.

to be able to hear more of the split in a broad pileup situation (like
the extremely large split widths that we saw a few
I just went through a very similar scenario. A few months ago I bought a
base K3 with one extra filter, the KAT2 and KXV3A. I purchased the kit
version. A couple of weeks ago I decided to add two 200 matching filters,

Thanks for the quick response. I was just going through the K3 manual

Sorry, but yes, the K3 audio is limited at 4 kHz, no matter whether it
is to the headphones or to the speaker. Please do not "shoot the
messenger". but that information is in the archives of this reflector in
several places - it has been discussed periodically.

You can do it cheaper by building a simple transistor circuit that allows you
computer to key the radio via the computer's RS232 serial port. Not quite as
good as a Winkeyer, but gets you on air very quickly so you can have a play.

Ed,
I would think you are hearing the results of a narrow passband rather
than DSP audio distortion.
I say that because in all cases with the K3, it is the DSP that
determines the filter width rather than the roofing filter. What I am
saying is that even if you put in a 1.8k filter, SSB at a 1

You don't need the 2.8 sub, stay with the stock.
Your CW choice is excellent because the K3 can go tighter digitally.
You don't need a wide FM filter unless you are going on VHF UHF FM with

I originally chose the 8-pole filters thinking the steeper skirts
would be useful should I ever take the radio into a dense RF
environment like it is in the lower-48 states. MY experience with CW

DSP filter. I chose the 2.8 KH
Most of the free and non-free programs have support. Look for the

A good friend of mine K1BX helps build these interface units. Set the K1 to
straight key mode and hook up this keyer to your computer. Can't help you with
the software but there's got to be some freeware logging programs out there
that can key this.
