Hello Bill,
I trust Elecraft engineers have already listened to some elecrafters' comments
as compared with the NR in Icom radios. Elecraft will find ways to improve the
NR by regular firmware updates.

I use the BHI in my mobile rig and could not live without it. Audio NR
only effects the spectrum going to the speaker and it really can reduce
the hiss.
I am going to look at Dayton to see if they have a stereo version, if
they do I will be bringing it home with me.

20 dB for both per spec. I suspect they're both LMS, but haven't tried the
Lingua. I do like the Hear It, even if it does have that watery LMS sound.
But it isn't the ultimate solution either. And as you say, it's worthless on
CW. Do I believe the other radio's NB are so much better? Nah. Not

the best NR (for my taste)
For NR I always use BHI (Gap Hear it) or Lingua
(http://www.ssbusa.com/LINGUA.html) products. They seem to be very similar
technology, with the audio implemented a bit differently.
If you use headphones for very weak signals in large amounts of noise, I
recommend the 10W BHI speaker, it has a n
So far, I have not used the K3+2m transverter on weak-eme CW, but
when I did quite a bit of eme-CW several years before the advent of
digital-eme I found the use of NR and DSP narrow BW filters (100-200
Hz) necessary to copy CW. This was using my FT-847 which has a more
limited DSP menu than

Johnny, look forward to seeing you at Dayton at either the Elecraft booth or
with Adam.
I also
ck because it becomes too aggressive.

This is why some of us use a relatively wide DSP filter (4-500 Hz) when
listen
All,
For basic noise reduction operation, the ADSP-2 unit in
the venerable SGC SG-2020 is about the best DSP I have
heard. IMHO it sets the bar for all DSP NR units.
The NR has 2 levels. The first level is excellent for
electrical noise and QRN removal along with a great
auto-notch funct
The K3 NR algorithm is a trade-off between noise reduction and stability.
The wider the dynamic range of signals presented to it, the more
aggressive it must be, which in turn makes it less useful for applying
small amounts of noise reduction.
The NR pays some attention to the settings of AGC S
Yes, i think the same.
Best ussable NR for me is from last Icom HF radios.
Like Tony told: It is not a major obstable, but ... i wish it was better.

Bill,
Could you refer me to those urls? This is a most interesting thread
about NR and NB. To date my K3 is not as good as my 756 PRO III.
However, I am still new to the K3 and believe it to be cockpit error.
Other than that the k3 is a dynamite box. AGC, interesting will try
working with that.

Ron,
I don't have the 5k to compare, but have read and tried all the settings of
the K3 for AGC and NR/NB. I have found the wide variety of settings very
beneficial as I can set the K3 for the best performance in my situation. I

I have a K-3, S/N 1997 and was talking to a friend who also has a K-3 on the
air recently. He mentioned that he also recently purchased a Yaesu FT 5000
and noticed that the noise reduction on the FT 5000 seems to do a better job
of reducing the noise while still having good copy on the signal.
