Re: [Elecraft] NR settings at AD4C K3 now available at my website
every case, SSB was harder to understand (muffled) with the NR on and in spite of the noise, much easier to understand with NR off. CW sounded great with NR on. My opinion. Steve N4LQ ~~ of my K3 receiver with all the settings I do use,also you will find a word with the explanation of all the settings and finally there are six AD4C I had replaced the newer 3.27 with the older 3.25 as the SSB NR didn't please me as much. But after examining your .doc file with settings I tried the 3.27 once again using the AGC settings in the .doc file. After changing a few settings the SSB was very nice and CW also seems to work fine. Here is what I did: First my RX equalization is: #1=0, #2=1, #3=1, #4=-1, #5=-3, #6=0, #7=0, #8=0 AGC HLD=0.15, AGC PLS=nor, AGC SLP=05, AGC THR=5, AGC-S=20 The setting changed from the .doc file was AGC SLP=05, from your 00, which didn't surpress enough some of the huge static crashes we were having. Then I found the SSB setting most effective to me was F4-1 and F4-2. They didn't exhibit the hollow/echo sound of F1- or F2- settings which I felt reduced the clarity of the SSB in noisy conditions. I use AFX a lot, but the same experience with it on or off. I am cw about 80% of time so experimented with it and had very pleasant results also. But following suggestions of more experienced users on this email group, I've found that AGC off and using AF about 50% and then using RF to control signal volume/intensity works much better in noisy conditions for me. The essence, then, is to try F4-1 and F4-2 with the new 3.27 to see how it may work for you if you use SSB mode. I'm continuing to experiment with different settings in various conditions as the type of noise effects what needs to be done to surpress it but enhance the signal. ...Edwin Once you have flown, you will walk the earth with your eyes turned skyward, for there you have been, there you long to return.-da Vinci http://bellsouthpwp2.net/e/d/edwinljohnson __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] NR settings at AD4C K3 now available at my website
David, Thanks for your input on this. I understood pretty much correctly, but appreciate your more complete explanation. By WAV, yes, I meant linear-coded whatever resolution. I think windoze Sound Recorder records files in this format. They're huge... As a function of my group's charter (at work), we sometimes run distortion analyses on MP3 vs WAV files for plain voice phrasing. They're used in turn-by-turn directions on vehicle navigation units. We'll run the WAV file on the X (ref) axis, and the MP3 on the y axis and snapshot different parts of the phrases with the display on short-term average. We've found differences of up to 10% distortion, though whether it sounds that way to a human ear I have no idea. I suppose it depends on the recording format of the MP3 (resolution again). A 12-bit sample looks the worst - easily naked eye visible. In practice, we use 16-bit sampling at 16 KHz for all non-Text To Speech pronuciations. This seems to work best and whatever distortion there is can't be heard by anyone I've tested. I was only questioning whether or not this would be a valid comparison, and it sounds like MP3 is probably OK for plain voice. Thanks for that answer. 73, matt W6NIA On Sun, 30 Aug 2009 19:30:14 +0100, you wrote: Matt Zilmer wrote: Does anyone have more input on MP3 vs WAV?

Re: [Elecraft] NR settings at AD4C K3 now available at my website
I'm still evaluating the NR settings here. On strong SSB signals, it sounds OK to me, but seems to limit or compress weaker voice signals. I've been pleased with the improvement to CW signals, though the settings available don't seem to change output characteristics much on a strong CW signal. Probably no surprise. Intelligibility is much better on F1-1 with weaker CW signals. MP3 files aren't necessarily the best way to hear voice. The masking (or compression) is pretty good for rock music, but tends to cut out a lone voice. Or classical music, which gets cut down a lot in terms of the dynamics. MP3 probably works well for CW though. For voice comparisons I've done / seen in the past, WAV files work ok. Does anyone have more input on MP3 vs WAV? 73, matt W6NIA K3 # 24 On Sat, 29 Aug 2009 10:36:15 -0600, you wrote: Ditto that. The CW performance sounds awesome. SSB... Better with it turned off.
