Mike, you could be correct. This morning I seem to have a little distortion
in the NB which I did not notice before. It's not bad, but a little is
there.
I may go back to 4.50 just to check it out.

Yesterday I wrote << NB settings are dsp T2-4 and IF NAR 4
After playing some more with this I think that a DSP setting of T2-2 may be
better as far as audio distortion is concerned.
It may depend on conditions, and finding the perfect setting for all
conditions may be impossible.

When AGC THR and AGC SLP are changed in the CONFIG menu, are the settings
changed for the KRX3 also or are there other steps? Thanks. Roy W4WFB

I seem to have missed the 4.51 release, though I got 4.50. Would
someone mind forwarding it over?

I have also missed the 4.51, and even the 4.50 release. The only beta

I can't really tell if there is an improvement due to the new log
algorithms but I really like the extended Threshold adjustment range.
I typically listen to CW on a wide filter setting and used to have my
AGC at Threshold 8 and Slope 0. Now I have Threshold at 15 and
thinking I should flatten the
If the adjustment allows half steps, e.g. 0, 0.5, 1, ... 8.5, 9;
then you would have about as many steps and still have some
vague relation to S units.

Took the FW4.51 for a spin at PI4D in the CQ-M on 20m in SSB and CW
yesterday afternoon.
AGC THR on 12, SLP on 10.
Smooth operation, NB performed OK for the key clicks from a nearby freq.

Was it better than FW4.48? Not sure, but I like it that the threshold

For taking care of key clicks, NB LEVEL set to DSP t1-7 or t2-7 and IF
*OFF* is best. I got excellent results with the milder t1-7 in 4.51.
IF ON is traditional IF blanking with all the traditional artifacts.
Kept on the K3 because it's still best for some kinds of noise.
Traditional IF blanking
Guy,
Well, both NBs create artifacts if pushed to hard.
I have not encountered any problems when using this config (DSP x-3 and
IF med-3). If I run any of the two NBs on x-7 it really becomes bad.
But your advice inspires me to experiment again.

I found on what I was listening to, that turning off the IF blanking
cleaned it up and t1-7 or t2-7 was incredible for key clicks. The
other thing was that I always carefully minimize signal input on lower
bands with ATT/ /PRE/RFgain at only high enough to bring up band noise
to moderate in the pa

I'm not a fan of NR, however since it's back in 4.51, I decided to try it
again.
I thought some of the NR settings appeared to be excessive, to the point of
eliminating the signal I'm trying to listen to. But then I remembered that
finding the best NR setting takes time (it's not instant).
Sebastian,
The AGC threshold is something the typical operator will rarely
change. We didn't make any effort to eliminate switching artifacts as
you change the menu parameter, though we could if it turns out to be
an issue.

I fail to see any advantage to turning on the preamp when it is not
needed. If you can hear the atmospheric noise without the preamp, leave
it off (if the noise level increases when the antenna is attached, you
have enough gain). By extension, if you can still hear the atmospheric

I certainly can't quantify it, but it seems to me that the APF does not work as
well now
as it did before 4.51.
It used to be a magic bullet.

As reported in earlier threads, 4.51 does seem to change the APF to a
broader, less peaky shape, but it is less "noisy", so the previous
impression of a signal jumping out of the tip of an inverted audio V of
noise is no longer there. You no longer have the inverted audio V full of
noise to tell y
liking. Yes, subjective I know.

We'll be doing careful measurements of APF pre-/post-4.51 this week.
There was no intentional change to it, and to me, at least, it still

The original APF never worked for me when used with weak 160m sigs in the
noise - the ringing made it more difficult for me to copy than without it.
I have not had a chance to try
The high Q goes hand in hand with ringing, I actually try to adjust for the
most ringing, hihi, it is hard to
explain but I find a more "piercing" sweet spot this way.

Wayne,
This may be entirely dependent on signal level vs. AGC threshold.
Prior to MCU 4.5x APF was generally working with signals that had
already activated the AGC thus the peaking occurred above the
threshold/slope. With the higher threshold, the noise is not held
to a well defined level so t
