Re: [Elecraft] K3S In-Depth Review Coming Soon?
Jim, Do you have Fred Cady's book on the K3? What audio and noise reduction issues are you experiencing ? I'm a new owner and a voracious reader and find learning to use the radio for noise reduction is pretty daunting, however, I also haven't had any noise issues that I couldn't adjust out to isolate the desired signal. I use the RF gain, pre-amp, roofing filtering, DSP filtering, NR settings, AGC settings, NB and NB settings. In my mind the key is to understand what each of these does, how they interact, general parameters of the received signals in the bandpass (pre roofing filters), and being able to actually hear the desired signal at to start. Just curious because my prior radio did a decent job but nothing even close to what my K3S does. I have the 400Hz and 2.8KHz 8 pole roofing filters installed and use a dipole for RX.

Re: [Elecraft] K3S In-Depth Review Coming Soon?
Mike, I have a different opinion and it does not rely on words like "tiring". In June, 2015, I went as far as sending my K3 (#04841) back to Elecraft with the headphones I use to take a look at the hiss issue I have when the volume control set completely counter clockwise, with *nothing* attached to the rig but a 12 volt car battery and the headphones. This hiss is always present when the A.F. gain is set for normal listening to signals. I have compared my K3 to two of my friends K3's and mine is the only one with noticeable hiss (pre and post service by Elecraft). I had Elecraft perform the "once over" making sure I had the latest fixes (firmware, gold contacts, etc)and install two of the latest and greatest SYN boards. The audio hiss is still present. I have worked around the problem by using the Timewave 599ZX which has no hiss that I can hear. Just as a side note, I used my Kenwood TS-480 rig when the K3 was in the shop, and found the audio was better than the K3 and the noise reduction algorithm was superior for my conditions. This, in itself, can be a complete new thread. Jim W6AIM P.S. The Elecraft service level is second to none, going to great lengths in an attempt to sort out the issue. . -Original Message- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Mike K2MK Sent: Tuesday, October 27, 2015 11:58 AM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] K3S In-Depth Review Coming Soon?

The speaker amplifier and driver stages that were redesigned are on the DSP board, not the KIO3B.

Hi Ian, Yes, I keep my K3 pretty well up to date with firmware releases, so if they are there I will have them. A little confused about the redesigned audio. You wrote about "redesigned AF output and driver stages. These upgrades were introduced in the new KIO3B module". As I remember the audio stage of my K3 is on the DSP board.

Re: [Elecraft] K3S In-Depth Review Coming Soon?
I'm not sure what they did, buy my new K3s sounds better to me than my original K3 (27xx S/N), as well as being better than the previous audio winner, my IC-7600. That said, I have some high frequency hearing loss making conversation in a crowd difficult. However, I could understand almost every one I heard during the CQWW contest last weekend. It was noticeably better and easier to listen to, than the '7600 Rx audio. Obviously, a personal thing, but I am quite pleased with the audio I'm getting from the K3s out of a pair of inexpensive computer speakers. The audio with the "AFX" enabled is a fun too. If you're only using one speaker, you owe it to yourself to plug in another one to experience the AFX mode. 73, Charlie k3ICH __ 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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] K3S In-Depth Review Coming Soon?
When I first got my K3, I was very disappointed by the receive audio. Hissy etc. I think everyone knows what I am talking about. It was not my friend for a very long time. It took me months of experimenting with the various menu settings and speaker selections, but I eventually turned the K3 into the best arm chair copy receiver I have ever had. Most likely, my settings would not be very good for contesting or DXing - but, they suit my needs. Make your own settings to please you. Be sure to keep notes - the K3 is complicated and it very easy to get lost in a never ending maize of menus. There-in lies why the K3 is such a great rig. The menus allow it to be be adjusted to suit the needs of nearly everyone.

Re: [Elecraft] K3S In-Depth Review Coming Soon?
Audio quality seems to be a very individual matter of taste. The language of audiophiles looks to be rivaled only by that of wine experts in trying to describe their taste. Radio communication audio doesn't have near that complexity, but there does still seem to be a lot of personal taste involved. I have a K3 that I purchased about 6 years ago. It has had all the update mods done to it (except for the KSYN3A upgrade). I also own a half dozen other RX, most of them of high quality. After setting the RX audio equalizer on the K3 to my own preference, I find that it is the easiest to understand and most pleasing RX audio of any of my receivers.

Re: [Elecraft] K3S In-Depth Review Coming Soon?
Operators disagree about K3/K3S audio. To me it sounds great, others dislike it. The best way to settle the question for your own, personal ears, is to find someone nearby who will let you use his/her K3S for a few hours. 73, Vic, 4X6GP/K2VCO Rehovot, Israel http://www.qsl.net/k2vco/ On 27 Oct 2015 19:53, Paul Clay via Elecraft wrote: I was wondering if and when a full-on review of the K3S would be forthcoming.

Re: [Elecraft] K3S In-Depth Review Coming Soon?
The recent ARRL review of the upgraded synthesizer performance is available in the current issue of QST. That, by far, is the biggest change in the K3S vs. the K3 (not that there aren't other changes, such as cw performance, LF rx, etc.) 73, Bob/AA6VB From: Mike K2MK To: elecraft@mailman.qth.net Sent: Tuesday, October 27, 2015 11:58 AM Subject: Re: [Elecraft] K3S In-Depth Review Coming Soon?

I've had my K3 just over 5 years--received in October 2010--and I've never experienced the "tiring audio". Still, this gets trotted out on various forums from time to time as an ongoing issue that has apparently never been resolved, at least to those who complain about it. Expressions to the contrary fall on seemingly deaf ears. Sigh. 73, Nate, N0NB -- "The optimist proclaims that we live in the best of all possible worlds. The pessimist fears this is true."

[Elecraft] K3S In-Depth Review Coming Soon?
I was wondering if and when a full-on review of the K3S would be forthcoming. I'm a bit surprised that following its release there hasn't been a lot of reviews posted (certainly no comparison to the number of reviews that followed the release of the original K3).
