The K3 filter is a little unusual in that the receiver equalizer is part
of the DSP bandpass filter, not a different or subsequent filter. This
helps minimize latency.
As a result, the equalization is applied before the audio paths are
separated, so it is on all receive paths.
In data modes

If you connect an antenna to either ANT1 or ANT2 (select the right one),

I got my KX3 first and was blown away by how quiet and sensitive it was.
The KX3 was so impressive I sold my entire Ten-Ten station and built a K3.
I was disappointed that the K3 receiver didn't seem to be as "good" as the
Travis, that's interesting that the KX3 was quiet. Sometimes I think the k3 is
just too sensitive. I don't know if that's it or not. I've certainly wondered.
Please share if you find the secret sauce.

Travis,
The KX3 is a direct to baseband receiver with the DSP being done at
baseband (or if RX shift is on at 8 kHz.) while the K3 downconverts to
the 8 MHz IF before digitizing and sending the data to the DSP.
So the two receiver architectures are different.

Thanks Don.
I will definitely tweak the AGC settings. Someone else recommended that
too. However, I thought the KX3 and K3 had basically the same receiver, and
if I hook the KX3 up to the same antenna that to which my K3 was connected,
the S-meter should report the same values regardless of the AG
Travis,
I doubt the RX gain calibration will make that much difference, but
rather I suggest that some alteration of the AGC parameters will make
the most difference for you. Take a look at the "Noisy K3" article on
my website www.w3fpr.com for some guidance in adjusting your settings.

Thanks for the link. I recall seeing the wire when I checked to see if
the IF out level mod had been done.

the ATTN is 10dB. Not sure where the CORs activate however. I do know
that I've hit them before though.. :)
Not sure if this helps you but I do also know that you can get to +20dBm
and as long as you have the extreme signal protection mod done to your
radio (or it was built after 9/1/2009) before

I think we may be comparing apples to oranges here.
In the K3 digital ANF, the notch filter is looking for coherent signals. The
premise is that audio is less coherent than a CW carrier. Thus the ANF "finds"
the coherent CW carrier and notches it out, leaving the remaining audio.

You said, "They have gotten so good lately that it is barely
preceptible, but its there, you can see it on a spectrum analyser.
(Google Sabine Adaptive Audio to see a representative device, their
older devices sound quite similar to what you hear in the K3 ANF; the
newer ones are truly magical!

ANF is the common use abbreviation for Auto Notch Filter. A
lot of rigs us
I also have a P3. I think the Notch is working very well as
currently designed.
