Dave,
It is unlikely, but possible that your 250 Hz filter is defective. My
original 400 Hz filter had a center frequency offset beyond the 250 Hz
correction limit (as an 8-pole, supposed to be 0 Hz offset).
If you can center the signal in another filter's bandbass (use CWT to be
sure) and then
In the recent discussions of this subject, I don't recall any mention
of Rx EQ settings, or FLx gain settings as ways of obtaining
more output. For CW operation, I'm using +10 dB gain in the
200 Hz and 400 Hz Rx EQ bands (my CW pitch settings
are always set between 300 and 400 Hz). I get

I don't recommend that you do this, although of course yo can. When you
go to 100 Hz or 50 Hz width, the RxEQ is no longer in effect so you'll

It's a risky to assume that ALL RX noise is uncorrelated after being
detected. While there may be

With much regret, I am selling my K3. I need to fund some international
travel after the first of the year. Here is what I have under the hood:

KAT3 Internal ATU
KTCXO3-1 TCXO
KUSB USB Adapter w/software
KBPF3 General coverage
I like the sound of the RX audio of my K2 with the KAF2 filter better than my
K3. It has less hiss and just sounds better - at least to my crummy ears..
I have played around some with the RX equalizer in the K3 and have improved
it some but has anyone had time to really find out what settings
I had trouble aligning on all bands with the KPA. So, I rewound T5 and
found D21 broken and replaced it. Now, the power is erratic. I once had
the 2 watts set on 7100 hz and now it won't go above 0.1 watts. Is there a
way to reset the K2 power output? I've gone clear back to the beginning and
Ron,
Do you have power output on any band? Try them and see.
The display of 0.1 watts is as low as it will indicate. An indicated
'output' of 0.1 or 0.2 usually means no power output at all.
Check the other bands and get back with us for further troubleshooting,

This is a software option I would like to have. Maybe it is already do-able. If
so, I hope someone will tell me how. If not, I hope this request will get put

What you say simply isn't true if one is using text decode or displaying
other VFO B slot parameters.

In general, the K3 DSP filters are sharper than those of the K2 w/KAF2.
One way to get some of the feel might be to use the PB feature in CW
I meant PB2.
Also, be sure to try AFX with stereo headphones. DLY 3 to DLY 5 can
make a real difference in the presence of a signal.
Enjoy!
73,
What you say is true enough. But I think when most people are operating split
they
have the VFO B normal display on and not the alternate display. Of course
nothing
like that is true all the time...but I think it is true most of the time.

Thanks Lyle, I had not thought of changing the delay on afx which I use all
the time. I wear hearing aids which may be part of my problem though I take
them off when using headphones. I'll try PB2 in CW and see how that works.
Don't get me wrong - the audio od the K3 is excellent just
Hi,
Before I bought the K3, I too, was concerned about the fact that the main

am no more. There are a number of indications in the display that I am in
