Though after I just checked the 'Config" and was pressing Menu again,
rather than the screen returning to the band I was on, I see "TERM" and
no other key-press except POWER had any effect. So I powered off then on.

Yesterday, twice, I saw "END" and the same effects of no keyboard.

So I am beginning to wonder if my K3 is dying.

Re: [Elecraft] Speakers for KX3

[Petr, OK1RP/M0SIS]

Grant,

thank for info about the Small Dog.
I used them for few days when my friend visited me over here and they worked
perfectly.
Nice and smooth audio.
Unfortunately no way to purchase them at Small Dog from EU as it will raise
up to almost $60 including s/h from them... :(

Re: [Elecraft] Speakers for KX3

Small Dog is selling the Chill Pill speakers for $10.00 on their website direct 
… Looks like they’ve been discontinued, and are on clearance.  For $10 I bought 
some to try.  Maybe they’ll be a little lighter weight than the Sony thing I 
lug around in my bag ...

Mine last 7-8 hours on a charge and in their carrying pouch, they fit nicely in

I tried using a consumer-grade "hi-fi" speaker in a VHF/UHF mobile
installation and the highs drove me crazy.  Pulled out the original
Motorola limited-range speaker from the junk box and the installation
sounded like it was supposed to.  The Big Emm knew what they were doing.  :)

Yes, this is VERY important in multi-op contest stations when operating 
SSB. The major issue is NOT sound on the air, but to minimize the sound 
heard by an operator while other operators are shouting into their mics. 
We contesters tend to get excited. Guys that have operated with the 
great operator Jerry, WB9Z, say that he doesn't need a mic!  I visited 
W3LPL several years ago and noted no sound treatment at all in a room 
having only hard surfaces. I urged extensive sound absorbing materials.


The room should NOT affect on the air sound if 1) you're working a mic 
within about 2 inches of your mouth, 2) TXEQ is set so that you're not 
transmitting below about 400 Hz, and 3) mic gain and compression are set 
so that you get no more than about 10 dB on voice peaks.

Ron,

Interesting you bring this up as the KL7RA (sk) super contest station 
had acoustic tile on the ceiling in the room with six contest 
stations.  I noticed immediately how nice voice sounded without echos 
off hard surfaces. Floor was carpeted.


When I build my new ham 18x26 foot shack I am thinking of installing 
some acoustic tile over the operating position (probably not the 
entire ceiling).  Floor will either be sealed concrete or maybe tile 
(embedded radiant heat in the concrete).  But perhaps a area rug 
would dampen echos?


This is how radio station booths are designed. Person on the mic 
sounds like next to you in your living room vs in a barn.


re: speaker linearity and THD also important as freq range.  I'm 
keeping my eight-inch National speaker in the big metal box.  K3 
sounds very nice with it.  For very weak signals I will be trying out 
bluetooth direct to my hearing aids.  I spent more for the hearing 
aids than my K3 plus accessories.

Re: [Elecraft] Speakers - Optimal Frequency Range?

[Walter Underwood]

OK, I know this thread is getting too long, but…

When my beloved Grado SR-60 headphones died, I used my Yamaha CM-500 phones for 
music. They were terrible. Not even good enough. So I ordered Grado SR-225e 
phones. And the cord for the SR-60 phones is part of my PTT hand switch. The 
CM-500 phones are back with the ham rig.

In general, good hi-fi reproducers should be good communications reproducers.

I definitely agree with using good quality headphones for optimal 
listening.  But, headphones are a different psycho-acoustical experience 
than a speaker system. Personally, I prefer to listen to a speaker 
system.  Headphones VS: Speaker system will be different for everyone. 
But, if you prefer speakers, i recommend decent quality components to

Re: [Elecraft] Speakers - Optimal Frequency Range?

[Walter Underwood]

I worked with someone who had two sound-absorbing pillars in the corners of his 
office. Of course, he’d just recorded his 8th or 11th album, depending on how 
you count, and he’d produced the latest one. Mitch Easter was busy this time.

I’m not nearly that picky and have some hearing loss by now, but I still miss 
my baby Magnaplanars (SMGa).

Need to write up my cheap-ham amp & speaker setup after I have a few more miles 
on it.

When you're sitting right in front of a loudspeaker you're in its near 
field. That causes what you hear to be dominated by direct sound from 
the loudspeaker. The loudspeaker(s) excites the room, but you're so 
close to the loudspeaker that you don't hear the room response. Most

headphones. The CM500, Sony MDR7506, and Etymotic Research ER4 are 
excellent choices. There are other good choices, but these are well 
established, widely available, and not expensive. All are VERY 
comfortable for LOOONG contest weekends (although comfort in the ER4 
depends on matching the ear piece to your ear).

Of course the room in which the speaker is used has a huge effect too.

Re: [Elecraft] Speakers - Optimal Frequency Range?

[Jim Brown]

Your logic is good, as usual. But let's look at the physics of 
loudspeakers, which I tried to do on an earlier post. A SMALL diaphragm 
has better dispersion of high frequencies, while it doesn't produce loud 
bass. We don't need loud bass, so a GOOD small diaphragm loudspeaker is 
what we need. And that is EXACTLY what Elecraft uses in the K2 and both 
versions of the K3.


The late Dick Heyser famously said that "trying to describe an audio 
device or system using only frequency response is like trying to write 
Shakespeare with only one word in your vocabulary. In addition, to have 
any meaning, a frequency response spec must include +/- dB limits and it 
must include angular dispersion. VERY few consumer loudspeakers do that 
-- they simply quote upper and lower limits.  Many cheap loudspeakers 
(and headphones) have very bumpy frequency response, and those bumps 
create phase distortion that degrades speech intelligibility.


So, to repeat my earlier advice, the best loudspeaker for ham radio is 
one that has smooth response from about 300 Hz to about 3 kHz and has 
wide, uniform dispersion within those limits. In other words, it sounds 
the same both on and off axis. Loudspeakers that cover a wider frequency 
range are FINE, but don't pay extra to get one. A loudspeaker with wider 
response would reproduce lower lows and higher highs, but our ham rigs 
(at least the good ones when well adjusted) limit audio to a range of 
about 300 - 3,000 Hz in the IF.


There is no good reason to buy a speaker rated for 300 - 3,000 Hz. What 
we want is one with good performance within that range, and most that do 
will have at least another octave or two above and below those limits. 
(An octave is 2:1 frequency)


BTW -- I purposely set my RXEQ flat because I primarily work CW, and I 
want to hear the off-frequency signals that may be very low or very high 
in frequency, and I limit frequency response on SSB with the settings of 
my IF filters.

Edward,

My last hearing test, I asked for and received a copy of my hearing
results.  I used to listen to CW at 650 Hz., and noticed that my speed
was slowing down as my hearing got worse over time.  

I noted a big dip in my hearing response at 600 Hz. from the results of
the hearing test.  I then changed the spot frequency from 650 to 540,
which is not nearly as depressed, I copy CW MUCH faster as a result of
that change.   

I in essence, have used the K3 EQ to adjust for my hearing deficiencies,
producing something much flatter between 300 to 3000 Hz. than I would be
hearing without the EQ.  

Over all this has really helped both my CW and SSB receive ability.

Hi Don,
I am saying that not using the speaker as part of the total
communications system is not effective use of hardware, having a speaker
that is flat beyond the audio output range of the radio is useless and
just runs the cost of the radio up.

You are assuming that receivers are all 300-3000, they are not, else
ESSB would never have come about.  We are not running broadcast
stations, we are running communications links.

Best communications is achieved using something close to 300-3000.  See:
http://www.w0btu.com/ssb_audio-weak_signal.html

In reality, it really would not matter if one put a high end stereo
speaker on the radio, assuming the radio were limited to 300-3000, (as
it should be), save a bit of amp noise leaking through...  

So, as I said in my original post, it is the most efficient use of the
hardware is to use a limited response speaker.  No need for high end
stereo speakers on a K3...  That said, I may put on some better speakers
on my K3 because in the long run it is a bit less stressful on my
ears...  :)

Re: [Elecraft] Speakers - Optimal Frequency Range?

[Edward R Cole]

As many of you know I suffer extreme hearing loss (especially high 
freqs), so Don's comment really hit home for me.  Several years ago I 
debated buying a home theater system with prof. speakers as I 
wondered if I could discern the improvement.  I found that having 
very linear response from 50-Hz to 20KHz improved understanding of 
voice on the TV as well as enjoyable music.


Later, I found choosing the flat response program in my hearing aids 
also provided the crispest voices and better understanding.


Long ago I bought a pair of Sony stereo headsets for listening to 
weak signals on ham radio.  Appears that also was a good move.


So even if the audio output is restricted to 300-4000 Hz the speaker 
reproduces that faithfully.


My new blue-tooth capable hearing aids have much wider freq response 
as I am hearing a wider range from low to high freq.  The plus is my 
iphone connects directly to my hearing aids for best hearing in 
public (and that half is private).  I have yet to try using bluetooth 
with my K3.  Let you know how that sounds, later.

Bret,

In my opinion, a speaker should not "color" the audio response of the
receiver.

While it is true that there is not normally much response above 4000Hz
from a ham transceiver, the speaker should not be the limiting factor.

IMHO, the best characteristic of a speaker is the flatness of its
response curve rather than its frequency range.  A speaker with a flat
response will allow you to hear the transceiver "as it should be"
without distortion. So my vote is for "High-Fidelity" speakers.

Re: [Elecraft] Speakers - Optimal Frequency Range?

[Don Wilhelm]

Dave,

While what you say (using the speaker as a filter) may have been 
advantageous in the days when receiver selectivity was "broad as a barn 
door".  I don't think that applies today for receivers have adequate 
selectivity to do that filtering job.  Some low end receivers that do 
not provide adequate filtering may benefit from a peaked speaker, but 
that is not true of any of the Elecraft receivers.


Besides, unless your "filtering" speaker matches the filtering provided 
by your headphones, there will be a vast difference when switching 
between the speaker and the 'phones.


In modern days, a flat speaker response in the 300 to 3000 Hz range is 
the best for communications.  If the speaker response is greater than 
that range, it will not matter because the receiver will not produce 
audio much beyond that 300 to 3000 Hz range.


To me, the goal is a flat speaker response in the range that the 
receiver produces audio.  The fact that the speaker is also flat beyond 
that range is of no consequence unless that same speaker is also used 
for Hi-Fi listening.

Au contraire, the speaker is as much a part of the radio as the
synthesizer, or the APF is.  We are not dealing with a high end stereo
here, (where the speakers should never color things, but frequently do),
we are dealing with the terminal end of a communications link, which can
be several thousand miles long, and as such, the speaker is just another
filter/device to reproduce the sound.  Filters by nature color things,
hence the speaker must color the sound if we are to use all parts as
efficiently as possible.

Re: [Elecraft] Speakers - Optimal Frequency Range?

[Ron D'Eau Claire]

Take a stiff card, book or even your hand and hold it at a 45 degree angle
behind the speaker and against the top of the K3 so the sound is bounced
toward you and notice the difference. It's dramatic!

Back in the K2 days, many hams folded some stiff card or paper to make such
a deflector to tape to the top of their rigs. (Most of us, like me, used
headphones so the issue was moot).

What matters is smooth (flat) response from about 200 Hz to about 3 kHz as
heard at the ear of the operator. The laws of physics dictate that
uniformity of high frequency response is limited by diaphragm size -- the
larger the speaker, the worse it sounds off axis. The speaker built into the
K3 is a nice small one, so it has pretty good off axis response, but it
faces straight up. In most shacks, the highs bounce off of nearby surfaces
to get to the listener. A front-facing loudspeaker will have flatter
response, but takes up more space on the operating desk.

Re: [Elecraft] Speakers - Optimal Frequency Range?

[Walter Underwood]

Converting electrical power to mechanical power is fraught with peril. One way 
to get excellent performance from 300 to 3000 Hertz is to have very good 
performance from 30 to 30,000 Hertz. Or something like that. We want to be in 
the safely linear portion of the speaker.

That said, I just bought some cheap Pyle speakers (two for $20) and am trying 
them out. Because hams are cheap. But I really wanted some of the old Radio 
Shack small two-way speakers. I have one of those on my Lowe HF-150 Europa and 
it is just fine, thank you.

Au contraire, the speaker is as much a part of the radio as the
synthesizer, or the APF is.  We are not dealing with a high end stereo
here, (where the speakers should never color things, but frequently do),
we are dealing with the terminal end of a communications link, which can
be several thousand miles long, and as such, the speaker is just another
filter/device to reproduce the sound.  Filters by nature color things,
hence the speaker must color the sound if we are to use all parts as
efficiently as possible.

Re: [Elecraft] Speakers - Optimal Frequency Range?

[Fred Jensen]

The Hallicrafters bass reflex speaker cabinet for the SX-28 had fabulous 
flat response ... down to the deep bass if you drove it with that.  It 
also employed a fairly large speaker and was big ... very big, and took 
a few watts [8 peak, I think] to drive it.


In the late 50's, in college and on a limited budget, it was common for 
students to use 5 or 6" speakers in tight cubic boxes made of 3/4" 
plywood and stuffed with some wall insulation for the then-new stereo 
records.  They sounded pretty good and doubled as supports for the 
ubiquitous cinder-block shelving.  My roomie and I painted ours black.


Why wouldn't one of those work?

Re: [Elecraft] Speakers - Optimal Frequency Range?

[Don Wilhelm]

Bret,

In my opinion, a speaker should not "color" the audio response of the 
receiver.


While it is true that there is not normally much response above 4000Hz 
from a ham transceiver, the speaker should not be the limiting factor.


IMHO, the best characteristic of a speaker is the flatness of its 
response curve rather than its frequency range.  A speaker with a flat 
response will allow you to hear the transceiver "as it should be" 
without distortion. So my vote is for "High-Fidelity" speakers.

[Elecraft] Speakers

[Raymond]

Different speakers so they sound different. In radios studios I always used a 
"cheap" speaker as a cue speaker so it could be distinguished from the air 
speaker.  
I use an Elecraft speaker for main and an inexpensive tinny speaker for the sub 
receiver.

[Elecraft] Speakers for K3

[Doug Ellmore]

I purchased a 4ohm/8 ohm 250w audio amp, then two 6x9 4ohm 200w speakers
and 6x9 enclosed car stereo kicker speaker cabinets.  I took a stereo
1/8 to dual (R/L) RCA connectors to connect the radio to the amp.  Then
speaker wire to the kicker boxes/speakers.

I keep the audio low when I turned on the radio and amp, then raise the
audio on the radio a bit and then the amp a bit.  I have great audio  I can
hear DX from anywhere in the house.

With the AM filter and AM station selected, it is like being in the
broadcast studio.

The little audio amp also works with my smartphone/laptop with a
appropriate stereo cable, too

Parts where all off of Amazon.

You can make smaller speakers that take up less space, but I have the room
for the larger speakers.

Hello

Since today, my K3 is not producing audio on the internal speaker or via an 
external speaker connected to the rear speaker socket
Audio is fine in my headest via the front or the rear connector

Time to time I can see HI CURR on the display. I must power off and on the 
eliminate it

Any idea?

Re: [Elecraft] Speakers audio is gone

[Mel Farrer]

Sounds like you have the same failure I do.  Take the cover off and look for 
the DSP PCB and on the upper left side top is U1.  Mine did not heat up or draw 
excessive current but was told that it might smoke smell bad and be hot to the 
touch.   I think your U1 the audio amp is the culprit.  I ordered the AF 
protection PCB assembly and a new IC from Elecraft.  Not expensive but a bear 
to replace the SMD IC.  Good luck

Re: [Elecraft] Speakers audio is gone

[Dave Hachadorian]

Marcel,

You have probably blown the speaker amplifier chip, U1 on the DSP
Board.  Many of us have had the same problem.  Elecraft has not
been able to determine the cause of the failures, so they have
not provided a solution.

The part is inexpensive, but is very difficult to replace because
the pins are very close together.  If you know an excellent
soldering technician, maybe they could do it for you.  Otherwise,
you have to send the radio, or just the DSP Board, for repair.

Re: [Elecraft] Elecraft Speakers for K3

[Mike Rodgers]

Most are satisfied with small speakers and some like the big 8-12 ones that 
seem to cut some of the high frequency hiss. 

It's not one size fits all and even a particular speaker size is not a one size 
fits all. I can see where a speaker enclosure that matches would be desirable 
for a lot of folks where you could install your preferred speaker. 
Look at how many $200 speakers with filters have been sold by the big3 to match 
their radios. 

I've used small ones, a kenwood one and currently using an old classroom public 
address speaker. It seems the large ones are hard to find around here. 

I've also finally got rid of my hiss/roar/frying bacon with the addition of a 
external equalizer and mainly pushing the 3.5 slider of the unit to -4 to -6db. 
(3.2 on k3 @-16). 
RFI was a bit of a problem for my close antenna.

Re: [Elecraft] Elecraft Speakers for K3

[Paul VanOveren]

I use 2 of the Yeasu MLS100 speakers thru a stereo adapter into the back
speaker jack of the K3. They are small, black and I think nice looking in
the K Line equipped shack, Main receiver on the left, sub receiver on the
right or both on with sub receiver off. Work very well in my opinion, and
only $49.00 each at AES...

[Elecraft] Speakers and other Bright Ideas… Maybe not so Bright...

[Phil Townsend Lontz]

Re Speakers and the KX3 and the KX1…
Has anyone considered the speaks used in the iPad, iPhone, iPad Mini and the 
iTouch?
The iPad speaker sounds darn good! 
I am about to pop the top on an older iTouch that has a built in speaker… Its 
sound is so so but maybe it would work for the KX1…

Ideas….

Anyone??

Re: [Elecraft] Speakers and other Bright Ideas… Maybe not so Bright...

[david Moes]

Interesting ideaI did that in a speaker mic that I used on an HT 
using a speaker element from a dead blackberry.   it sounded much better 
than the original.My only worry is the original speaker used and its 
magnetic shielding may be important.If I replaced it would I be 
creating potential problems if I cant shield the magnet properly.


(i dont have either KX1 or KX3  but often thought a better speaker 
driver in the K3 would be nice but dont want to take the chance of 
adding a problem)

Re: [Elecraft] Speakers and other Bright Ideas… Maybe not so Bright...

[David Moes]

This is true in many cases.   however in many small devices like phones 
and such put decent modern drivers  in that will sound pretty good 
without all the electronic wizardry that the device uses to make it even 
better   my speaker mic was proof of that.Its amazing how the fine 
points of speaker driver  have changed  in the miniature world of today 
yet the basic principle is still the same as the good old Rice Kellogg 
design of 1924.



Where the speaker, its driving electronics and the enclosure are all 
in one package, there's great scope to compensate for all the 
short-comings of the arrangement with sophisticated (software) filters 
which you will not get when you salvage just the speaker which is not 
in itself optimised for clarity - it's the whole ensemble.

[Elecraft] Speakers

[Karl Marderian]

 Speakers for ham radio should cut off at about 100Hz.. Leave the  
HiFi, for music. Music that is from a high quality source.
   I am sure there are many good choices out there. The one I use  
fits the size of my K3. It is Vertex mobile speaker, made by Yeasu. It  
has ahold sound and it is very well made. Also it looks good with K3.

[Elecraft] Speakers and more

[Bill]

Lots of good posts regarding speakers.   I suspect many others have the 
problem I was faced with: too many speakers.

2 for the K3, one for my K2, 2 for the PC, 2 for a small AM/FM set, 2 
for my VHF/UHF FM rig.

I picked up a Behringer RX1602 (~$130 today), 8 stereo inputs, each with 
an on/off button, balance, gain, and clipping indicator.  Two outputs: 
one for the speaker pair of your choice and a headphone output with 
level control on the front panel.

I built up a set of isolators for each input pair just to be safe and 
have no RF issues at legal limit into a variety of antennas.

Now have the mixer and one pair of speakers - much less clutter.

I use a pair of these on my K3, but they're actually KLH Audio Systems

in your boat, patio, workshop, etc  The company's website rates them 
at 4 - 6 ohms, 40 watts. 

The company address is 11131 Dora Street, Sun Valley, CA 91352.

Dan,

Computer speakers are intended to play music and sound effects, not
communications audio.

Get a communications speaker. Mono, no amplifier, no sub-woofer.

Even better, use headphones.

Re: [Elecraft] speakers

[Don Wilhelm]

Dan,

I see no need for a sub-woofer for use with the K3.
If you are running an amplifier, you may want to look at shielded 
speakers (usually non-amplified) because those with amplifiers are 
usually prone to RF problems.
The K3 has adequate audio to drive non-amplified speakers.  If you use 
AFX or you have the subRX you will want 2 speakers, but there is no need 
for any more than that, the K3 does not do Dolby Surround sound or 
anything of that nature.

If you want great low-frequency bass response in shielded speakers you 
may have to look to what is available in the pro-audio field, but for 
only communications quality, the Motorola speakers available on Ebay or 
at hamfests will do the job for you.

Re: [Elecraft] speakers

[Mel Farrer]

Hi all,

Just a comment on speakers.  I use cans or a small computer speaker, 
non-amplified, for most SSB and CW work.   However, I do a reasonable amount of 
SW and BC listening with the K3 with the 6KHz filter and find an old HiFi combo 
speaker with a 8 woofer to be most pleasant to listen to.

Hi Dan:

I am looking at speakers for my K3. I have looked
At the various computer speakers but don't know
Which of the many available would work best. Does
Anyone have an opinion on which set is best :-).
Also should I get a set with a sub?

Some (possibly many) PC speakers include internal amplifiers which can be
susceptible to RFI which results in thumps 'n 'bumps in the night.

I have settled on a pair of (UNamplified) 8-Ohm Motorola mobile speakers
I bought off EBay for $5 each, plus shipping.  They are a very dark brown
case, which is almost dark enough to be taken for black, and match the K3
nicely.

Trying top plug two (2) separate (UNamplified) speakers into the single
1/8 stereo jack in the back of the K3 was getting to be a PITA... I had
two wires going different directions (L and R) RIGHT OUT OF THE BACK OF
THE K3, which made things a bit 'busier' than I wanted.  So I fabricated
a 'splitter' for the speakers... a single 2-wire/shielded cable (about
8 long) to a 1/8 stereo plug goes into the back of the K3. The cable
terminates in a small PC board containing two (2) 1/8 STEREO jacks of
which only the TIP and SLEEVE are used (RING = N/C). This allows me to
plug in speakers which are terminated in mono OR stereo jacks and to not
have to worry about possibly plugging a mono plug into the stereo jack
on the K3.  Yeah, I know, there have been mods for the K3 to prevent
damage if I mono plug was plugged into the stereo jack, but this helps
to ensure that I never do it regardless of the preventative mods!  It
also helps to get the two wires (to the two speakers) out and a bit away
from the immediate read of the K3, making wire 'congestion' a bit easier
to handle.  Thought I've not done so (yet), if there's any interest in
the 2-speaker 'splitter', I'll put the info out on my web site for general
access.

Re: [Elecraft] speakers

[Monty Shultes]

All this talk about speakers prompted me to resurrect a pair of Apple 
amplified speakers that have very good frequency response.  All was well 
until I tried 10 and 6 meters - then got the thumps and bumps in the form 
of a loud hum.  Tried FOE (ferrite on everything) first with no success. 
Opened up the speaker and found not one bypass capacitor.  I put one 
(.01ufd) across the power plug, and after zapping the amplifier module, one 
across each of the stereo amp's power inputs.  Perfectly quiet now.

 Some (possibly many) PC speakers include internal amplifiers which can be
 susceptible to RFI which results in thumps 'n 'bumps in the night.

I've had very good results with a pair of Sony B-1000 
bookshelf speakers.  They're just slightly larger than 
the Insignia/KLH and can often be found at Radio Shack, 
Best Buy and others for $49.95 (per pair) on sale.

 Hi Dan,
 
 I recommend a pair of Best Buy Insignia, 4-inch, 3-way surround  
 speakers (same as the KLH Model 970A or other similar 
 models). These  
 are unpowered bookcase speakers, but provide plenty of volume when  
 used with the K3. They're very inexpensive and sound great. Size:  
 about 4W x 8H x 4D.
 
 Having two speakers allows you to get L/R separation of the main and  
 subreceivers, as well as take advantage of the K3's AFX simulated  
 stereo mode.
 
 73,
 Wayne

[Elecraft] Speakers

[Phil LaMarche]

Wanted to share.

When using a speaker with my K2, I experimented with many and settled on the
Sounds Sweet speaker.  I liked it so well that I have it in my AM station as
well.  Part of my R388/Globe King 500B combination.  Really great.
