K3S audio board for K3 upgrade?

Guy Olinger K2AV
Haven't heard about this for a while. Supposed to be cleaner audio and
higher power audio output. Any word?

Re: K3S audio board for K3 upgrade?

Grant Youngman
Good question.  It’s the DSP board from the K3S (the performance difference being the audio).  Maybe a supply issue, still (?).

Re: K3S audio board for K3 upgrade?

lstavenhagen
I dunno, the K3S audio actually isn't much better to my ears. Yes, it's a little better on my K3S compared to my K3, but still kind of shrill and fatiguing to listen to for long periods of time. I'm not sure it'd be worth spending a ton of money on to upgrade if there was an upgrade path.

Don't get me wrong, I love my K3S; the best rig you can buy, IMO. But I still strongly prefer the smooth, low sounding audio of my K2. I never get tired of it....

Soundly seconded! I love the amazingly quiet noise floor and the K2's ability to dig out the weak signals. It's a very pleasant rig to listen to.

Does a decent speaker and amp being fed from the speaker out sound any
better?  I have a computer speaker on the K3 now, and I also want
better sound...

Re: K3S audio board for K3 upgrade?

lstavenhagen
Well I don't want to complain _real_ loud either lol. The audio on the K3S really is better. But only slightly - not better enough to spend money on an upgrade for the K3, imo, which is kind of what I was responding to. Basically, save the money for filters, etc....

A good set of hi-fi headphones helps too, but I definitely still tire of my K3S in a fairly short time even with headphones, especially if the band is noisy. I find myself engaging the DSP and monkeying around with it rather than concentrating on QSOs to try to relieve my poor ears on a noisy band. Course it's even worse with my K3 lol. I've not found the equalizer to help that much either with either rig.

Might just be my aging ears too, so take my comments with a grain of salt. And when I'm /p, I'm usually at around 10,000 feet above sea level out in the woods miles away from industrial noise sources. My K2, K3 and K3S are all quiet as mice in those conditions, but by far my K2 is the preferred rig to run there, even without the creature comforts of the K3/K3S....

Change the audio equalizer settings for received audio. When using a headset
you can tune the audio to your ears pretty well.

Do you listen on the internal speaker or on headphones? CW or SSB? Have
you used RX EQ to shape the tonal balance? How do you set the IF
bandwidth and centering? If headphones, which type/model? If external
speaker, which one?

I'm retired from a career in pro audio, including lots of live
recordings of acoustic jazz. My operating style is to use the speaker
only for casual monitoring when I'm doing something else in the shack,
and to help me tune in digital signals. I listen mostly on headphones,
both Yamaha CM500 and Sony MDR7506. The Sony headphones are widely used
in recording studios, and the sound of the CM500 is pretty close in
sound quality. I'm quite satisfied with the sound of my original K3s. I
don't use any RXEQ at all.

Re: K3S audio board for K3 upgrade?

lstavenhagen
I use both the internal speaker and a set of Sony headphones (not comm. style, but basic hi-fi, can't remember the model number offhand) on primarily CW but on very rare occasions I'll go up to the SSB bands from time to time for listening/entertainment purposes. I do own a microphone, but I'm not sure where it is right now.

But speaking of SSB, I will say that SSB is where the difference from the K3 is most noticeable, even through the internal speaker. Not an order of magnitude better, but noticeable. So for you voice ops it may be a more worthy upgrade? Voices are definitely flatter and smoother sounding through the K3S.

For casual listening and for comparison with my K3, I run the BW at 2.7khz with the center at the stock 1.5khz (IIRC). As I noted above, it's in SSB signals that I suppose there's a more noticeable difference but the regular noise when operating CW still has approximately the same shrill quality on both rigs (headphones and internal speaker). It's hard to quantify, but it's just has that harsh, upper midrange kind of rasp that the K3 has as well.

For equalization, I've tried reducing the upper mids and boosting the lows to emulate my K2, but it doesn't really replicate the K2 regardless of settings. So I just leave those flat.

Finally, I should mention I do have some mild hearing damage from many years as a musician, so I just may be more sensitive to heavy mids/upper mids types of equalization than others. So again, just take my comments with a grain of salt. Just because I can't hear much improvement doesn't mean there isn't an improvement or that others won't benefit from it :).

In this day and age, with PC soundcards and excellent freeware audio spectrum analysis software (like Visual Analyser), I wouldn't settle for subjective opinions like "shrill and fatiguing."  Feed whatever audio output you're listening to into your soundcard and run a passband plot of your favored radio against the K3s and TELL US why you don't like the K3s sound.  And then "fix it" (i.e., your preferred sound) with the filter and EQ controls.  I'm assuming, of course, that you're listening through the same speakers or headphones on both radios.

Folks, this ain't rocket science or magic.

Re: K3S audio board for K3 upgrade?

lstavenhagen
My apologies fellers, I didn't mean to turn this into a let's-bash-the-K3S-audio thread LOL. Probably what I should have said is something less absolute. Perhaps something like I personally don't notice much of a difference between my K3 and K3S but that doesn't mean there isn't a difference period that noone else will notice.

As for the why's and wherefore's of what I don't like, I've noted that in my other responses. Again, for me, it's the upper mid kind of rasp of the band noise that I find to be similar between the two rigs. And what I find to be much better on the K2.

Again, just my observations - I didn't mean to sound like I'm making general statements, that's my fault for which I duly apologize.

Re: K3S audio board for K3 upgrade?

Don Wilhelm-4
LS,

If your problem is more related to "band noise", you may want to
investigate the AGC Threshold and Slope settings on the K3 and K3s.
To my ears, the K3/K3S sounds a bit 'noisy' with the default AGC
settings.  Increasing the Threshold and decreasing the slope may help.
For information on evaluating the results of any changes, refer to the
"Noisy K3" article on my website www.w3fpr.com.
Pay particular attention to the points about observing the results
during pauses in a transmission.   Attempting to listen only to the band
noise with no signal present will result in changing the settings in
exactly the wrong way.

Don W3FPR

Re: K3S audio board for K3 upgrade?

lstavenhagen
Ok thanks for the suggestions, Don. I should also mention that the other posters are quite right to call for objective, independent measurements to verify impressionistic judgments like my earlier ones. I stand by "shrill and fatiguing", :), but I concede that's just a personal judgment based on my particular hearing.

I'll take a look at the AGC settings, though to be quite honest, I think they're already ideal on both my K3 and K3S. I can't see how the AGC on either could be any better?

Thanks es 73,

In reply to this post by Don Wilhelm-4
I have always felt the K3 was a looser in the audio department - but,
with the many menu settings available - most of the problem can be
mitigated.

There a lot of things that can be done with the menu settings on the K3
(presumably on the K3S also) that effect the RX audio - EQ settings, AGC
settings, etc. I have posted my favorite settings in the past - it took
weeks and weeks of tinkering to find settings for common armchair copy
listening. I do use Behringer MS40 speakers also (no RF problems ever
experienced).

The really sad part: My Kenwood TS480 out "sounds" my K3 right out of
the box. Just saying a fact, so no flames please.

My point was that free tools are readily available to all of us to conduct
a quick investigation into exactly what the sound differences are and to
tailor the sound of a K3/K3s to our liking.  There's absolutely no reason
to continue to use a radio that is "shrill and fatiguing."  By all means,
investigate it, adjust it and FIX it.

Re: K3S audio board for K3 upgrade?

All excellent points. My personal fix is to use my K2 at home where the band noise is bad (I refuse to mix computers and ham radio at the same time, so this may not be the fix you have in mind :) ), but when I'm /p, it's a non-issue. I use all 3 of my rigs when portable with no audio issues.

Re: K3S audio board for K3 upgrade?

In reply to this post by N1EU
Berry,

Actually it is quite complicated to define what is wrong with the
"sound" of something...  What makes audio "fatiguing", exactly?  I
can't say, and no amount of listening to it, or playing with the EQ has
fixed it in my case...  

I used to work in a recording studio, as a mix engineer, (way back
when), and recently was in charge of the construction a Dolby
certified, (almost fully digital), mix down room for movie sound design
a few years ago...  This was one of those rooms within a room on rubber
bumpers sort of thing...  So I know a bit about audio.

Nor does using some non certified soundcard does not sound like the
path to pristine audio...

Re: K3S audio board for K3 upgrade?

Doug Turnbull
In reply to this post by lstavenhagen
Friends,
     Perhaps it is because I largely operate CW but for me the original K3
audio is just lovely.    I am 71, my hearing is not so great but I use the
lowest pitch possible around 360 Hz and have RX EQ set for good performance
at low frequencies.   It is just a sweet sound to me and so restful.   Maybe
if I was a phone man the story would be different though I do monitor SSB
and work it for rare DX and it also sounds good.    

     Could it be that the great flexibility in setting up the audio results
in some people being put off as they have not found the sweet spot for their
ears.    I seem to remember a few years ago many people had troubles with
the FT2000 because it was complex to set up.   There were also people who
did not like the Orion II again because setting the radio up initially was
problematic for them.  

     Now I may be completely wrong in my analysis of this situation and
please God no one feels their toes have been trampled.   This is not my
purpose but for me the radio has a wonderful warm sound.   We are all
different.   Some people like a Sicilian Pizza while others like a
Neapolitan Pizza.

Subject: Re: [Elecraft] K3S audio board for K3 upgrade?

Well I don't want to complain _real_ loud either lol. The audio on the K3S
really is better. But only slightly - not better enough to spend money on an
upgrade for the K3, imo, which is kind of what I was responding to.
Basically, save the money for filters, etc....

A good set of hi-fi headphones helps too, but I definitely still tire of my
K3S in a fairly short time even with headphones, especially if the band is
noisy. I find myself engaging the DSP and monkeying around with it rather
than concentrating on QSOs to try to relieve my poor ears on a noisy band.
Course it's even worse with my K3 lol. I've not found the equalizer to help
that much either with either rig.

Might just be my aging ears too, so take my comments with a grain of salt.
And when I'm /p, I'm usually at around 10,000 feet above sea level out in
the woods miles away from industrial noise sources. My K2, K3 and K3S are
all quiet as mice in those conditions, but by far my K2 is the preferred rig
to run there, even without the creature comforts of the K3/K3S....

Re: K3S audio board for K3 upgrade?

That's been my experience too, "really great sound" is somewhat akin to
pornography ... as Justice Stewart said, "Impossible to objectively
define but I know it when I see [or hear] it."  I inherited an SX-28
with the large bass reflex speaker a number of years ago.  As a ham
receiver in the 21st century, it left a lot to be desired, but it really
"sounded" great on BC stations, and those stations on 75 at night
pretending to be BC stations.  I can't define "fatiguing" either, but
running AFSK at 915 Hz MARK, I start getting a headache after 4 or 5 hours.

My hearing is severely compromised, and I never use the internal K3
speaker and have never had anything plugged into the EXT SPKR jack.  I
have a Heil Proset from Elecraft and recently acquired a David Clark
aviation headset.  K9YC gave me a tip on the RX EQ to get the equivalent
of about 30 dB of equalization out of it.  My settings approximate one
of the "programs" in my hearing aids [30 dB isn't nearly enough but it
helps] sufficiently that I can dabble in NAQP and SS SSB.

My TS-480 also sounds better than my K3.  My K3 was sent back to factory to
see if there was an audio issue with my particular K3.  They compared mine
to a factory unit, using an audio spectrum analyzer and noted that my K3 and
a new factory K3 were "the same".

The TS-480 just sounds better to these ears.

Oh, and it is magic........

I have always felt the K3 was a looser in the audio department - but, with
the many menu settings available - most of the problem can be mitigated.

There a lot of things that can be done with the menu settings on the K3
(presumably on the K3S also) that effect the RX audio - EQ settings, AGC
settings, etc. I have posted my favorite settings in the past - it took
weeks and weeks of tinkering to find settings for common armchair copy
listening. I do use Behringer MS40 speakers also (no RF problems ever
experienced).

The really sad part: My Kenwood TS480 out "sounds" my K3 right out of the
box. Just saying a fact, so no flames please.
