Re: [Elecraft] external speakers

[Dick Dievendorff]

I found (and I can't remember where) a molded cable that had a 3.5mm TRS stereo 
plug and two longish cables with RCA connectors, one for each speaker.  I cut 
the RCA connectors off.  Look for a cable that you can peel apart all the way 
to the 3.5mm plug.

You can of course solder this up yourself, but molded plugs seem to survive 
better at my station.

Re: [Elecraft] external speakers

[Don Wilhelm]

Todd,

The best way is to build an adapter.  The shell and ring connect to the 
right speaker and the shell and tip connect to the left speaker.
Use whatever connectors you want for the speaker end of the adapter, and 
build cables to the speakers to match your choice of connectors.  The 
- terminal of the speakers should connect to the shell of the 3.5mm 
stereo plug.


You could eliminate the adapter and wire two speaker cables to the 
stereo plug eliminating the extra two connectors, but that means if you 
want to move things across the room (or elsewhere) the two speakers are 
tied together with the speaker cable.  If that is not a problem for you, 
the - conductor for both speaker cables connects to the plug shell, 
the + conductor for the right speaker connects to the ring and the + 
conductor for the left speaker connects to the tip.

Re: [Elecraft] external speakers

[Joe Subich, W4TV]

The correct answer is:  Both black wires go to the sleeve of
the 3.5mm plug (ground).  The red wire from the LEFT speaker
goes to the tip of the 3.5mm plug.  The red wire from the RIGHT
speaker goes to the ring of the 3.5mm plug.

How you manage that transition is up to you.  I put 3.5mm plugs
on both my speakers - the left speaker was connected to tip and
sleeve while the right speaker was connected to ring and sleeve.
Both 3.5mm plugs were connected to a Y cable (3.5mm stereo male
to two 3.5mm stereo female) which plugged into the speaker jack.

Re: [Elecraft] External Speakers for K3

[Edward R Cole]

I have a great radio speaker made in the 1950's by the National Radio 
Company.  11x12x8 inch metal cabinet with 9-inch diameter speaker (no 
amplifier).  K3 sounds very nice with it (I also have a Sony stereo 
headset when I need to hear even better).  CM500 sometime in my future.


The current HK computer speakers used with the KX3 will be replaced 
by a West Mountain amplified speaker which is immune to RFI (my wife 
is using a pair on her desk top to eliminate my RF).


If Elecraft ever considers it, a generic K-line cabinet would be 
desirable for making a pretty station.  One could install whatever 
in it.  No need for a speaker, power supply, and several other 
accessories that are obtainable anywhere.

I use the amplified speaker for the KX3 in the mobile and it helps a lot by

Re: [Elecraft] External speakers for K3

[Jeff Cathrow]

While I tend to agree with the OP I also understand that it would be a rather 
mundane task for Elecraft to manufacture speakers and that their talents are 
bettert utilized in updating firmware, advancing the technology inside our 
great rigs and so on. What I did do to achieve great audio was put a pair of 
5.5 Dynaudios (Danish audiophile grade woofer/mid-range drivers) in a pair of 
gray PVC junction boxes obtained from Home Depot.  I cut the appropriate-sized 
mounting holes in the cover panels, stuffed some cotton balls inside, ran some 
tiny speaker wires through a small hole in the back and mounted the speakers 
with some nice stainless steel screws. Arguably overkill but since I already 
had the drivers on hand I thought why not put them to good use?  They now 
elegantly perch atop my gear---and best of all---make the K3 loud and clear!

[Elecraft] External Speakers for K3

The K3 lacks matching external speakers offering better sound than the internal

include a power supply in the enclosure (but I would be content with just a 
good sounding speaker). Any hope for this?

Re: [Elecraft] External Speakers for K3

I agree with those who say it is in our and Elecreft's best interest for them 
to concentrate on what they do best and let others excel in their own 
specialty.  Speakers and power supplies are in that category.  Probably not a 
lot of Return On Investment in designing speakers.  Not a lot of gain for 
amateurs either.  As this is one of the recurring threads you can find plenty 
of good suggestions in the archives.

Re: [Elecraft] External Speakers for K3

OK   no speaker  since they do not make speakers,,,\
but they could sell an enclosure  , P3 form factor
grille punched out with internal standard mounting studs...
for whatever that size hole could reasonably accommodate
leaving the rest of the space for us to chop up for whatever we want./...

one could even make a subframe to take smaller speakers than the main 
hole would permit... stuff you sdr in the back of your second speaker...

Speakers do have better intelligibility when they are facing you 

I can do speakers, I cannot due a matching enclosure properly,.,,,

No need for an Elecraft speaker here.

Why talk about one speaker by the way?
I use a set of computer stereo  speakers. I need two speakers for my K3 
(main RX and sub RX in nice stereo).
The sound is good en more than adequate. For the price I got those, 
Elecraft can never compete with that. And I gues they won't.

I agree totally with Bill,

There are lots of speakers out there and it is the lack of a suitable matching 
K3 line case that is the issue. A pre-punched case with standard positioned 
mounting holes would be a good addition to the line up, for purchasers to add 
their own speaker to. As Bill says, intelligibility is best from forward facing 
speakers and a good quality 6 diameter speaker would sound great.  Just make 
sure that a stereo jack is used for the rear jack socket...

I am good at speakers but do not have the capability to make a decent matching 
enclosure.

Lets sow the seeds at Elecraft  for a well finished matching enclosure for 
users to add in a standard speaker of their choice.

 OK           no speaker  since they do not make speakers,,,\
 but they could sell an enclosure  , P3 form factor
 grille punched out with internal standard mounting studs...
 for whatever that size hole could reasonably accommodate
 leaving the rest of the space for us to chop up for whatever we want./...
 
 one could even make a subframe to take smaller speakers than the main 
 hole would permit... stuff you sdr in the back of your second speaker...
 Speakers do have better intelligibility when they are facing you 
 
 I can do speakers, I cannot due a matching enclosure properly,.,,,

P3 front panel is slightly less than 4 x 6 and will not accommodate

There are plenty of speakers to choose from on the market and do not cost
that much either. As far as power supplies I would rather use my own a large
one to power many different things in the shack I use 2 Astron 70 amp
supplies a VS and a RS-70M.

Re: [Elecraft] External Speakers for K3

[Tom H Childers]

I use a pair of 4.25 square Realistic, AKA Radio Shack,
Communication Speakers that are wired up to a stereo plug.

Works great!

I'd rather Elecraft spend their design and development time on
something like point and click tuning for the SVGA adapter of the P3.

Re: [Elecraft] External Speakers for K3

[George Dubovsky]

I don't use speakers a lot, but the best sounding ones I have ever used
were the ones designed for land mobile radio in-car use. The GE Mastr II
and the GE/Ericsson Delta speakers were designed to be rugged and were
tailored for communications audio. I'm sure Motorola had equivalents, but
I'm not all that familiar with their product line. The speakers are
generally found under tables at hamfests for a few bucks. The black/gray
Delta speakers even match the Elecraft line... ;-)

Re: [Elecraft] External Speakers for K3

[Jim Lowman]

If you search the archives for this list, either Wayne or Eric use and 
recommend the Chill Pill speakers.  They are intended for use with iPods.
I can't see Elecraft wasting their development time on a product that is 
widely available from many other manufacturers, and at a range of costs.


I could see a matching enclosure for a speaker and power supply, like 
Drake did with the MS-4 and AC-4.

I use a set of computer stereo  speakers. I need two speakers for my

The sound is good en more than adequate. For the price I got those, 
Elecraft can never compete with that. And I gues they won't.

With the extra amplification and volume controls I can set the K3 volume

Re: [Elecraft] External Speakers for K3

[Don Wilhelm]

I was fortunate to find a pair of Radio Shack Optimus speakers (5 inch 
black cube) at a 2nd hand store for $5.  They work great with my K3.  
You may be able to find something similar if you shop around a bit.  
These are non-amplified speakers and work quite well, no worries about 
RF feedback or other problems that sometimes occur with amplified 
varieties, and the K3 has more than adequate audio to drive these high 
efficiency speakers.


Since the K3 tailors the audio response, there is not really a need for 
communications speakers - the RX EQ will shape the audio to your 
desires, so full range speakers will work great with the K3. For those 
who do SWLing, the full range speakers may be better for those users 
than communications speakers.

Re: [Elecraft] External Speakers for K3

I have a pair of vintage 5 bookshelf Hi-Fi speakers left over from my
1970's hi fi setup that I incorporated into my operating position design
that do a wonderful job for me. Their enclosures are nicely finished wood
enclosures about 6 by 8.

They are actually the supports for a bridge about 6 above the operating
desk that carries the K3, KPA500 and P3 and leaves the desktop under them
clear for keys and other stuff.

[Elecraft] External speakers for the KX3

[William Levy]

I think the KX3 is a great little radio. I tend to loose it like my Mac Air.
It disappears under bags and cables etc.

My question to the list. I am looking for a good active or powered speaker
to use with it.
Something that I could use in the shack or portable to give me more hi fi
and wattage than the small qrp
audio system. Something that runs on 12 volts or batteries that is as
portable as the KX3.

I would be interested in what members are using that would be RF proof too.

At the moment I am tying it into a small stereo amp that has an Collins
R390A on the other side.
One weighs in a 80 pounds the other at 1 1/2.

Regards to all, Bill N2WL

Small but sound great and no hint of any RF problems at up to 500 watts.  No
longer made but if you can find some they work well.  Powered by 4 D cells
or external 6 volt source.  They automatically turn them selves off after a
few minutes without any input and come back on when it is resumed which
helps save batteries.  I power them with an old 6 volt cell phone charger
wall wart I had in the junk box.

 They run from a 14V supply and the power input is a regular barrel type

 need for another wall-wart. And they only cost £7.99.

Dear Bill,

In my own humble-opinion the BEST ext. spkr for the K3 is one made by SOUNDS 
SWEET (Google 
it!)
It may be a TAD larger than some would want by their rig BUT I assure you that 
the resulting audio
to the Human hard-drive will be very sweet indeed!!!  As I recall the retail 
price is now 
$109USD
but well worth the investment!! Though it is a tad larger than most and 
heavier it's resulting
audio output is FANTASTIC!!!

Re: [Elecraft] External speakers for K3?

[Bruce McLaughlin]

Gosh, I have nothing very fancy.  I have been quite pleased with a speaker I
bought from RadioShack for about $20.  It is slightly less than 1 foot high
and perhaps 8 inches wide.  It carries the brand name RCA on it.  It's
probably made somewhere in China.  However, it does sound pretty good.  On
CW, I tend to use earphones as I like the closer coupling you can get.  I'm
sure there are many more hi-fi options available but honestly this speaker
I have appears to reproduce most of the audio spectrum coming from the K-3.

Re: [Elecraft] External speakers for K3?

[Bill Maddock]

Bruce,

I just ordered a set of 3 speakers on Ebay - They are Cobra
HG-S100 - I am hoping That they will be good - My K3 is only 4
high - these are 5 inches high and have a 4 speaker. I will
let everyone know how it turns out and compare them to my
current Kenwood SP31. The HG-S100 look good in the pics. 
Price was right at 41.50 or so for all 3 shipped to my door!
They offered HG-S300 and HG-S500 with some kind of noise reduction.
I figure I'll let the K3 handle that - for that price I can find
something to go in the 3 cases if I don't like the sound!

Re: [Elecraft] External speakers for K3?

[Tom Hammond]

Brendan:

For general communications use I am very fond indeed of the speakers
Motorola made for their various mobile rigs over the years, They are
very cheap, efficient and sound great for good quality communications
audio. These are not Hifi speakers but for speech / CW they do a superb job.

Mostly they seem to be a pretty close match in size and colour for the
K3 too.

I agree completely.

Some of them are 2 Ohm though, The ones I use with My K3 at the moment
are 2 Ohm ones, Since I do not know for sure if the AF amp in the K3 is
happy driving an impedance this low I stuck a 2Ohm 2W resistor in series
with each speaker and still have more than enough audio in my shack.

I have seen these available in 4-Ohm and amplified variants too. Pretty
much every radio in the shack is connected to a Moto speaker and I still
buy them at rallies, collecting stuff I might need someday must be habit

Anyone know if the can K3 drive a 2Ohm speaker without bad stuff
happening ?

In a recent e-mail from Lyle Johnson, KK7P, he stated that, while not
'designed' to drive 2-Ohm loads, the K3s AF amp should probably work
OK BUT that if one attempted to drive the speakers too hard, and the AF
amp attempted to draw excessive current (and starts to overheat), the amp
would go into a protective shut-down mode, rather than risk damaging itself.

For what it's worth, MOST (possibly all nowadays) of the newer, plastic-cased,
Motorola NON-amplified speakers are now 8-Ohms... there may be some 4-Ohm
speakers in the newer-style plastic ('fitted back') cases, but I suspect that
almost all have now been switched to 8-Ohm speakers.

I'm using a pair of 8-Ohm Motorola speakers on my K3 and it sounds just fine.

Cheers,

Tom Hammond   N0SS

Re: [Elecraft] External speakers for K3?

[Joe Subich, W4TV]

I would not use any speaker less than 8 Ohms with the K3. 

The audio amplifier draws more current and distortion increases 
as the load impedance decreases.  Best case THD+N vs. frequency 
for the audio amplifier is three times WORSE with 4 Ohm loads 
compared with 8 Ohm loads.

2 Ohm loads are not even spec'd.

Hi Joe,

I've used 4-ohm speakers with the K3 for over two years and have yet to 
hear any distortion at moderate speaker volume. As long as the RFC47 
modification has been made on the RF board, the AF amp chip can easily 
source the peak current needed for 4-ohm loads. It's true that in any 
AF amp, distortion increases as load Z goes down, but this is a floor 
effect compared to other factors usually present (atmospheric and pulse 
noise, AGC dynamics, transmitter IMD, etc.).

The only problem we've had is with mono speaker plugs in conjunction 
with a setting of SPKRS=2, which can result in excessive AF amp 
current. But this situation is detected and corrected in the latest 
field-test firmware revision. I'll be releasing it to beta shortly.

Re: [Elecraft] External speakers for K3?

[Steve Ellington]

By match closely, do you mean physical appearance or impedance?
Speaker characteristics for SSB and CW may differ. The best overall 
compromise I've found over the past 45 years is the Heathkit HS-1661. It is 
very efficient, as in LOUD, has a thick aluminum cabinet with no vibration 
or peaky resonance. Radio Shack sells a replacement speaker that fits 
perfectly if needed.
For CW only, the MFJ ClearTone, MFJ-281 is hard to beat. It peaks strongly 
at 700 Hz and is very sensitive. Cost about $12.
The HS-1661 shows up on Ebay occasionally and usually sells for about $30 or 
so. I painted mine black.
Modern stereo speakers will work but they usually have higher power ratings 
and require more power. Amplified speakers will also work well but could be 
affected by RFI depending on brand and model.

Re: [Elecraft] External speakers for K3?

[Peter Howson]

Go for two, then you can take advantage of AFX.

I use two small black communications speakers, designed for vehicle mounting and
optimised for voice and are only 3-4 mm taller than the K3 -- one either side.
Really does enhance AFX on SSB and they look good too. And they were less
than GBP 7 each!

This can only happen if you have CONFIG:SPKRS set to 2. If you set it 
to 1, the right speaker channel is turned off, so a mono plug can be 
safely used.

In addition to this, an upcoming beta firmware release detects the case 
where SPKRS is set to 2, a mono plug is inserted, and speaker volume is 
set to a moderate or high level. (The firmware looks for excess 
receive-mode current drain due to the AF amp IC going into thermal 
shutdown.) If this happens, the K3 will automatically set SPKRS to 1, 
reminding you with a brief flashed message.

[Elecraft] External speakers for K3

[Craig Smith]

I've been quite pleased with the Comspkr from West Mountain Radio.  Good sound, 
small size, volume and low cut controls, no RFI and a pair is quite reasonably 
priced.

Re: [Elecraft] External speakers for K3 - A caution

[Joe Planisky]

Wasn't the mod described at 
http://www.elecraft.com/K3/mods/AF_Output_Mod_Rev_C.pdf 
  intended to prevent the IC failure if a mono plug was used?  Did it  
not work as well as expected?  Or is the firmware detection just belt  
and suspenders protection in case someone didn't do the hardware mod?

 This can only happen if you have CONFIG:SPKRS set to 2. If you set it
 to 1, the right speaker channel is turned off, so a mono plug can be
 safely used.

The bleeder resistor modification helps prevent an instantaneous 
current surge when an mono plug is inserted, and is definitely 
recommended. It has already been phased into production.

The new firmware provides protection in the case where high 
right-channel speaker volume, in conjunction with the insertion of a 
mono plug, results in extended high current drain at the AF amp chip.

For general communications use I am very fond indeed of the speakers 
Motorola made for their various mobile rigs over the years, They are 
very cheap, efficient and sound great for good quality communications 
audio. These are not Hifi speakers but for speech / CW they do a superb job.

Mostly they seem to be a pretty close match in size and colour for the 
K3 too.

Some of them are 2 Ohm though, The ones I use with My K3 at the moment 
are 2 Ohm ones, Since I do not know for sure if the AF amp in the K3 is 
happy driving an impedance this low I stuck a 2Ohm 2W resistor in series 
with each speaker and still have more than enough audio in my shack.

I have seen these available in 4Ohm and amplified variants too. Pretty 
much every radio in the shack is connected to a Moto speaker and I still 
buy them at rallies, collecting stuff I might need someday must be habit

Anyone know if the can K3 drive a 2Ohm speaker without bad stuff 
happening ?

I would like to use two external speakers with my K3 setting them up one
on each side of the radio. Has anyone found something that somewhat
matches in color and size to the K3 and has a good sound?  Seems like
Kenwood used to make a smaller speaker that might work. Would like to
hear from anyone who has a similar setup.

Re: [Elecraft] External speakers?

[Don Wilhelm]

Tim,

Not addressing the aesthetics of the speakers, but pointing out other 
considerations.


In addition to the K3, do you have other audio sources that you want to 
listen to while in the shack?
If the answer is 'yes', you may want to consider something like I have 
here - reasonably good stereo speakers (mine are the old RS Solo-3B) 
that are fed by an audio power amplifier.  Ahead of the amplifier is a 
Behringer 802 mixer that has inputs from an FM tuner, a tape deck, and 
the K3 as well as connections in and out of the computer soundcard.  The 
sound is great.


The soundcard feeding the mixer is different than the one connected 
direct to the K3 line-in/line-out for use with digital modes.


I cannot comment on the RF immunity of this setup.  My antennas are all 
resonant and located more than 80 feet from the shack, so there is 
little possibility of RF in the shack.  Others with non-resonant 
antennas close to the shack location may experience problems.


Consistent with Jim Brown's (K9YC) recommendations, the computer is 
bonded both to the radio and the mixer, and they are all powered from 
the same AC outlet.

Personally, I like the UNamplified Motorola Mobile Speakers.  I 
bought a pair of

them a month or so ago for about $9 each, not including shipping, off EBay.

They're 8-Ohm (wish they were 4 Ohms though) but give a very nice sounding
audio and the black color goes nicely with the K3.

RE: [Elecraft] External speakers?

[Ron D'Eau Claire]

Yeah, I have a pair of LabTech SS-700 speakers that I've had around for
quite a while. They are black, just about the same height as the K3, and sit
nicely and unobtrusively alongside the rig. 

 

While they have amplifiers, it leave it off  so they operate straight
through. They sound FB.

 

Those are old speakers, but they're still around. Shoot, I just checked and
saw a brand new pair still in the original box offered on e-bay for a
current bid of $0.99!

The CB sections of most truck stops sell a variety of
suitable external speakers.  Mine are Barjan 320-701's.
Radio Scrap has similar speakers, too.

[Elecraft] External speakers for the KX1

[Paul Huff]

Hello everybody,

I was out running errands with my wife today and we stopped in at a Bed, Bath,
and Beyond store.  While she was in line to do a return I noticed a 50% off
clearance display that included a great little set of amplified speakers that I
am going to use with my KX1.  The speakers are manufactured by Excalibur
Electronics and are called “iBlaster Cube.”  They are intended for use with an
iPod but should also work great with any little QRP rig that uses stereo earbud
output.  The speakers fold up into themselves, are powered by 4 AAA batteries or
an included wall wart, and have a short lead that plugs directly into the
earphone jack on the KX1.  On sale they only cost $4.95!  I plan on using them
when I demonstrate my KX1 to others – no more “cheek-to-cheek” earbud sharing
necessary!   I don’t know if the sale was unique to this one store (Westland,
MI) or if others will also have them.  They had a pretty good supply on display.

73
Paul – N8XMS
