Has anyone tried either of these products out on a K3 and care to share their results compared to using the built in 8 band equalizer built into the K3. I am not interested in any comments by others who have not actually tried these out. If you would like to take this discussion off list please contact me directly. If someone has these products and is willing to set up a schedule on the air all the better. Thanks

Even I don't have those boxes anymore I can tell that about a year and a half ago when I sold my ProIII to replace it for my actual K3,I kept the W2IHY 8 bands EQ and the companion EQ Plus which I used together with the ProIII. When I received the K3 having its builtin EQ flat I tried those two W2IHY boxes and had no sucess at all,only noise and distorsion was what I got,I ended up selling them up. As Jim said,the K3 has an excellent 8 bands TX EQ that will allow you to EQ any mic,also it has a builtin noise gate that works great,save your money and don't buy them.

I too agree with Jim on this point. Myself, being a retired pro audio guy
and used lots of microphones and EQ's and processors, I've not seen the need for EQ on any current production or model ham radios. Take something made back in the 50's or 60's or 70's and they likley could stand some help. Even today should one use a lousy mike on a new radio and then add compression, gating and EQ and you'll have a lousy sounding signal with lots of compression, gating and EQ. No amount of EQ will make the average hams' voice sound like Don Pardo. Microphone and microphone technique is the real secret to good sounding audio. Of course one must have the radio adjusted properly and thus not "all knobs to the right" to make the meter move higher. 73 Bob, K4TAX ----- Original Message ----- From: "Jim Brown" <[hidden email]> To: <[hidden email]> Sent: Sunday, April 25, 2010 8:28 PM Subject: Re: [Elecraft] W2IHY 8 band equalizer and EQ Plus > On Sun, 25 Apr 2010 13:59:58 -0700, Ron Gould wrote: > >>Has anyone tried either of these products out on a K3 and care to share >>their results compared to using the built in 8 band equalizer built into >>the K3. > > As a pro audio guy who has used hundreds of equalizers, I can tell you > that > the TX and RX in the K3 are all you need, and that adding anything > outboard > would be a waste of money. > > 73, > > Jim K9YC > > > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:[hidden email] > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

The only EQ Plus and W2IHY equipment I have heard on air to date have been
little short of dreadful to my ears....But that's MY ears, and they are the only ones I have and the brains DSP is most likely not that crash hot either at my age. Having said that, Jim has hit the nail on the head, and he should know, of all people. I listened to a guy with an old Collins and the W2IHY etc...yep it sounded good..but it sure was wide let me tell you. Oh well, YMMV but I agree with Jim and Hactor et al, save your money, if you have the gear, then sell it off I guess. 73's Gary - VK4FD On Mon, Apr 26, 2010 at 11:58 AM, Bob McGraw - K4TAX <[hidden email]>wrote: > I too agree with Jim on this point.

Hello Ron,
I use a W2IHY 2 band equalizer and noise gate with my K3 and am VERY PLEASED with the performance. I highly recommend it! I don't use it for trying to customize my transmit audio fidelity or anything - I think you could do that very successfully with the K3 adjustments, if you wanted to. As a point in fact, I have never changed my K3 audio output settings at all. The reason I use the W2IHY unit is for the excellent noise gate that it provides. It very effectively cuts out the background blower noise, and I get excellent on the air reports with it. When I acquired my K3, I tried to use the noise gate built into the K3 so I could keep the W2IHY unit connected to my old IC746. However, I could not seem to adjust the K3 noise gate to avoid getting reports of audio distortion :-( So, reluctantly, I had to disable the noise gate in the K3 and return to the external W2IHY unit. Best wishes for success!

It is ALWAYS good practice to use the minimum mic gain needed to get good modulation, use no more than about 10dB of compression/processing, and roll off the low frequency content.

On the K3 what would be the approximate setting for 10dB compression?
AB2TC - Knut

Page 26 of D6 owner's manual, text states that the number displayed is
the approximate compression in dB. Or 10 is 10. 73, Guy.

I have to agree strongly with Jim - for me, the K3 does not need any form of external processing or "extras". I receive an unusually high number of unsolicited comments about the quality of my audio. In fact, here is the latest email I have received about it after working a few NA contacts on the 75/80m DX window:
-------------------------------- Hi Andy, I was talking to David, W6ANR today he informed me you are running K3 transceiver and you had the best audio he has ever heard from any K3. So I am asking if you could give a run down on all your setting as you have them on your radio that pertains to Audio so I can help my neighbor Bob, W9KNI get his dialed in. His sounds lousy and he has always been a CW man but has now been enjoying using the mic instead of the paddle. He has had comments that he need to dial in his audio so I told him I would help. SO maybe with all your setting etc I can have a good place to start as I am not to familiar with that radio. I hope your summer was a good for you? Here we are anxious for spring to arrive so I can get out and do some real work out in the yard and get the veggie garden started. Best 73, Rich K7ZV -------------------------------- Here is my reply to Rich: Hi Rich, Great to hear from you - it has been a long time since we have worked on 80/75m. I haven't been very active lately, due to work and family commitments. I hope I am not going to disappoint anyone when I reveal my audio setup on the K3 as it is far from spectacular..hi hi. The fist mic I was using is a five dollar CB type that you could find at any hamfest (no kidding!). I have not adjusted the TX equalizer so it is still at the factory default (all "flat"). I do use the compressor, but only allow it to indicate between about 5-10dB on the meter. I also always make sure the ALC bargraph indication is well below the upper limit. For what it's worth, my mic gain is set to 23 and the compression setting is at 19. Not very fancy is it? I found the K3 to work well "out of the box". As the old saying goes "if it ain't broke, don't fix it". -------------------------------- I think this speaks for itself - nothing else required! Andy VK4KY |

Yes, and watch the ALC level while you are doing it. I found that you can increase the compression and not trip the 5-7 bars of ALC, but it will sound terrible. Stay below 10 dB of compression and under 5 bars of ALC for the smoothest sound and lack of splatter. FWIW.

I am using a Heil Proset, IC element, Mic gain to LO, setting 35 and compression set at 20. With this I can not talk the CMP reading above 10 or the ALC reading above 7. I get good audio reports and just as importantly I get heard remarkably well by DX stations.

I said it before and written it before, good audio has to do with a good
mike and GOOD MIKE TECHNIQUE. The best mike money will buy and poor mike technique will result in poor audio. We use noise gates in the professional audio studio to create special effects. The noise gate used on ham radio to eliminate blower noise is a false since of secuirty for when the gate opens, along comes the noise with the voice. It only chops the noise in between words. It is still there with the voice. 73 Bob, K4TAX > On Mon, 26 Apr 2010 16:18:01 +0000, Lance Collister wrote: > >> It very effectively cuts out the background blower noise > > Some of the major causes of audible background noise are 1) working too > far from the mic; 2) running the mic gain too high; 3) using too much > compression/processing; and 4) not rolling off the low frequencies. > > In a noisy environment, it always helps to work close to the mic.

And do remember, more compression brings up background noise between
words by the amount of the compression value. Hence with 10 dB of compression, a background noise level that would normally produce and output of 1 watt will then sound like 10 watts of noise. 73 Bob, K4TAX > > On the K3 what would be the approximate setting for 10dB compression? > > AB2TC - Knut > > > Jim Brown-10 wrote: >> >> <snip> >> In a noisy environment, it always helps to work close to the mic.

Professional announcers use proper mic technique *and* they work in sound booths or acoustically inert studios. Sports announcers who must work in noisy environments use headsets with high quality noise-canceling mics inches from their lips, followed by processors far more sophisticated than any used by hams. A tip to the phone contest fellows: prepare your CQ loops in a quiet room well in advance of the event. I am always astounded at the poor quality of the CQ loops in contests - many from the well known big gun stations who should know better. I wonder about the impact on the Q-rate when the listeners (especially those whose native language is other than English) have difficulty understanding the CQ loop. 73, john WA1ABI ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

And things seem to be getting worse with every contest. At least 10% of the SSB signals I hear are so badly processed that the audio is so badly distorted that I can't copy the call sign, even if I listen to it a dozen times. And yes, some of these lids consider themselves big guns. Several times in the last month or so, R1FJM has been spotted on 20M SSB. I'd like to work him, and I can hear him, but his audio is so awful I can't understand a word. If someone knows him, please tell him. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |
