[Elecraft] Re： K3 Noise Reduction Improvement

[Johnny Siu]

Hello Dan,

I share the same observation for NR of my IC7600.  If K3 had the same 'manual 
notch within AGC loop' as that in IC7600, I would rate my K3 even higher in the 
rank.
 cheers,

主題： Re: [Elecraft] K3 Noise Reduction Improvement


I'd have to agree with you, Roy.

In a moment of weakness many months ago, I purchased an IC-7600.  While it's a 
nice radio, it is NOT a K3 nor would I ever use it in a contest or try fighting 
a pile-up with it (unless it was the only radio available).  That said, with all 
the 7600's lackluster features, the Noise Reduction (NR) on the ICOM far, even 
greatly exceeds the NR in the K3.  The noise reduction itself, the quality of 
(remaining) signal (QoS), and its ease of use is a marvel and my benchmark NR 
behavior.  While in the K3 you can usually find a decent NR setting, by no means 
is it easily configurable with it's convoluted algorithm scheme nor is the 
resultant QoS as clean.

My opinion only; YMMV.

I have two K3s and the NR is the same on both.  If I had to identify a feature 
on the K3 that needs improvement, I would have to say it is the NR.  I cannot 
find a noise reduction setting that is suitable to me.  I realize this is a 
subjective, and you would have to compare the K3s noise reduction with that of 
another radio.  I have owned the Ten-Tec Omni VII which in my opinion has the 
best NR on SSB without a doubt.  I believe it is all in the NR programming and 
how the algorithms are set up.  There has been considerable improvement from the 

time the K3 was introduced, but I believe there is still room for further 
improvement.  I would like to see noise reduction with a minimum loss of signal 
fidelity.    Roy Morris  W4WFB
