The AM or FM filters allow setting a DSP bandwidth of slightly more than
4 KHz. WSJT-X handles that just fine and is handy when activity spreads
out a bit. For me this is a carryover from dual mode JT65/JT9 activity
Having enabled 13kHz roofing filter for digital modes, i enlarge K3 DSP filter

I monitor with 4 kHz or 5 kHz bandwidth and sometime call up there just to see
if anyone thinks the same way I do.That's a habit formed when working
JT65+JT9. You sometimes find interesting
I find 2.7 kHz to be optimized. The software does the heavy lifting. And the
software has limits on the low and high frequency tones.
If you use the new FT-4 mode it uses slightly different frequencies on each
band.

Richard,
You may have better luck with Noise Reduction than the Noise Blanker.
The noise blanker works best on impulse type noise.

Hi all,
Has anyone had any success using the K3S noise blanker to get rid of the
new-ish FM-on-pulse types of over-the-horizon radar? I've tried various
settings but nothing seems to make any discernable difference.
There seem to be two main systems, both Russian:
'Sunflower', a surface-wave
Thanks to all respondents. To clear up one point... "Migration," as per
Elecraft, means to transfer whatever components in a K3 that will work
to a K3S. In my case, just filters. I end up with a new K3S and the
original K3, ie two radios. I have never operated SO2V in a contest. So,

Hi, all concerned:
My previously-owned K3S sn 11000+ passes the 5W & 50W tests, but won't
output more CW power than:
70W on 160M
80W on 80M
90W on 30M
70W on 15M.
The rig goes right to 110W on the remaining bands.
I suspect bandpass alignment problems,
or forbidden adjustment of caps/pots,
and
I am migrating my K3 [Ser# 6232] to a K3S with a sub-receiver. In the
K3S main receiver I will have the following crystal filters from the K3:
2.8Kc 8-pole Elecraft
1.9kc ?-pole Elecraft
0.5kc 8-pole Inrad
0.2kc 5-pole Elecraft
I operate almost exclusively CW in contests and DX chasing. in
My K3s has been in service for several years. Power output has always easily
reached roughly 100 watts.
Now, with:
1. ATU TUNE bypassed
2. Good 50 ohm dummy load
3. W1 in line with the load
4. SWR 1:1
Next:
1. With the PWR control set to show 100 watts on the LCD
No Problem, thanks for putting the time into this. I contacted the MacLoggerDx
tech support and they helped me out pretty quick. Just have to remember to
completely quit the program after making changes to radio prefs. These are the
working parms…
Don’t you hate it when the culprit is so simple?
Glad you found it.

Brian,
Yes, the K3S has both an internal FTDI USB to serial adapter and a USB
soundcard - Usually the computer identifies it as USB AUDIO CODEC.
The connection shown on page 19 is for a basic connection using an RS232
port (or adapter). If you do it that way, you would not use the USB
Sorry folks this has probably been asked a 1000 times before.
I’m connecting my new k3s to my mac for the first time. I’ve used MacLogger DX
lots with other radios including my kx3.
Page 18 of the k3s manual describes the first function of the USB port as
“Commands from logging/contesting
Thanks Bill. Yes, that seems to have been the problem.
