Re: [Elecraft] Elecraft K3 versus Yaesu FT-1000D

[Ken Kopp]

I also sold an FT-1000D that I bought new, and thought
it was a great radio, and it was ... until I got my K3.

Also sold an FT-990 and IC-756 PRO II at the same time.

Of course, I'm "preaching to the choir" here ...

[Elecraft] K3 how often do you use it?

[Doug Phillips]

Every day, sometimes 24 hours per day running WSPR.  It is the most 
amazing radio I have ever owned!

[Elecraft] Elecraft K3 versus Yaesu FT-1000D

[Steve Ireland]

G'day

 

It has been interested in reading the thread about a (or some) 'big gun'
contesters still preferring the classic FT-1000D over the Elecraft K3.

 

I used to have two FT-1000Ds (sold an FT-1000MP to buy the first one - the
FT-1000D's audio peaking filter and nicer receive audio gave it the edge).
I sold the first FT-1000D to buy a K3 and then sat the two alongside each
other in a series of contests.  I have two keen contesters nearby - one
about 1km away and the other 10km away (which is a really nasty distance on
the low-bands).

 

The FT-1000D's blocking dynamic range (BDR) could barely cope, but with the
K3's BDR  and the 500Hz roofing filter I could not tell if the other blokes
were on the same band unless they came within under one kilohertz of me on
CW. On the FT-1000D, I could hear them 3 or 4 KHz away and it was impossible
to operate much closer to them than 2 to 3 KHz on CW, making me miss
stations regularly.

 

Within six months I had sold the other FT-1000D and have never regretted it.


 

The FT-1000D may look and feel a million dollars in comparison to the K3
(and is a great radio), but I know which one gets the job done better at my
QTH in a contesting situation.

Re: [Elecraft] K3 how often do you use it?

[Hector Padron]

There you go Phillip,and you should say also that ON4UN considered one of the 
"BIG GUN" dxer in the world replaced his two Tentec Orions,another very high 
performance radio for two K3's,that says it all.
Thanks for your comments and by the way I bet your dog dentist must be very 
expensive,haha,73

Hi Gang,

performance etc.etc...
By Hams, for Hams, that's the Ham spirit who has been a little bit

are automated and not let the user to go beyond the limit if they want
to.
The design looks not like those pretty rigs, so what ! 
After testing on lab most of the commercial and Hams rigs on the market
for years my only regret was not to order a K3 earlier, thanks to John
ON4UN, who convinced me !
As a exclusive wire antenna user, what a great help for chasing the
weak signal especially in a industrial environment as mine.
In cw it is a great performer and in ssb it's not bad too with the 2.8
+ 1,8 khz 8 poles filters where you can discriminated easily a weaker
signal in a overloaded environment. 
The Electraft team are taking care of the comments of the users to
improve day after day their products, what can be expected more for us ?

I'm just a little bit anxious about the continuity of Elecraft company
when Wayne and Eric will be retired but no doubt they will find somebody
in the pure Ham spirit as they are.

Hi Randy,nothing more away from the actual reality what your friend
said.
He is obviously not updated with what is going on in the contesting and
dxing world of hamradio lately,IF he were then he sure will know that
precisely the "Big guns" as he call the major dxers on the world are all
selling their big FT-1000D,FT-1000MK5,FT-2000D,.etc to buy K3's.Wy?
because they all have realized that the K3 is a better performance radio
than those mentioned before.I even know two guys here in my county who
after owning for a year the IC-7700 and IC-7800 top guns from Icoms are
selling them to buy K3's.
I am not a heavy contester neither dxer but I use my K3 day by day,I
will say 365 days a year and its not an ugly radio,certainly is not
beautiful as a FT-2000 but guess what, I owned a FT-2000 and it lasted
here in my shack just 2 months because it did not passed the comparison
test againts my K3,neither the ProIII that I owned before,neither many
radios that has passed by here.
I will ask your friend If he could pull a weak station with a signal of
55 on 40M having at just 2Khz below another station with 20db
over,surely he will lose the weak one using those "big" radios,that
don't happen in a K3 where using a roofer of 1.8Khz and moving the shift
down 50Hz the QRM will totally disapear,that is something you can't do
with any of those big radios,that is why all contesters are switching to
this small size radio that is also very portable and light enough to
carry it to anywhere on this planet.
Ask your friend why last year at the Ducie island VP6DX all the radios
were K3's,they did not take any of the big radios for sure,not even
one,only back up radios they took were the K2's.
The K3 has probed to be the highest performance radio in the market and
If someone don't believe it,that is his problem.

[Kevin Rock]

Good Evening,
   Weather has been soggy this week but today it was simply heavy fog.  That 
makes it easier to carry in the wood for the day.  I have not seen any deer or 
elk in quite some time.  I think they are living far down in the valleys.  The 
Gray Jays are keeping me company so I give them left over popcorn and rice.  
They seem to like that.  
   Propagation was odd for most of the week.  I could hear some folks but they 
could not hear me.  I also received emails stating others could hear me but I 
could not hear them reply.  Reciprocity is in the theory but not always present 
in practice.  Hopefully that will not be the case when we run the nets 
tomorrow. 

Please join us tomorrow evening.

Re: [Elecraft] [K2] K2 PC Interface for N1MM

[Don Wilhelm]

Tom,

The timing problems are a product of the multitasking and interrupt 
processing in Windows, and not a fault of the K2 (or K3).  So the real 
answer depends on the computer that you are using.  If you are using a 
dedicated computer to do the 'hamshack chores', and there is nothing 
else running to steal cycles from the keying mechanism, then you will 
likely have good results without the WinKeyer.  But if your computer is 
doing multitasking and as a result has delays before the keying 
interrupts can be processed, then you will either have to "suffer the 
consequences" or use the WinKeyer which avoids these problems.

Re: [Elecraft] K3 how often do you use it?

[Brian Machesney]

I sold a "big rig" in deference to the K3. Many of the "big screen" features
of the "big rigs" - and more, I'll wager - will be provided by the P3 at a
price which will *begin* to put the K3+P3 combo in the same league as the
"big rigs" but still with the performance advantages that many Elecraft
owners value.

For me, this highlights the SUPERIORITY of Elecraft's marketing - you can
pay for only the features you need: output power, 2nd receiver, portability,
screen size, etc. I'd like to have this kind of "unbundled" value from my
satellite TV provider!

My take:

35W drives my amp to 1.5KW on CW, can't see the value of a 200W

The "looks" of my K3 are just beautiful. Not as good looking as my

Re: [Elecraft] K3 how often do you use it?

[Don Wilhelm]

Randy,

That is one man's opinion, and it is not shared by all.  The K3 
ergonomics went through a sizable focus group before final decisions on 
such matters were made.  Yes, that group was heavily influenced by 
contesting types and DX types, and they seem to be the groups that will 
purchase whatever will give them an edge on the competition.  Your 
opinions may differ, but the portability aspects for DXpeditions along 
with the high performance receiver has gone a long way - it sold over 
3000 K3s in under 3 years.  There is something to be said about that 
fact despite what some would call "shortcomings" such as a small front 
panel.  The K2 received similar criticism over its 10 years, but folks 
are still buying them. 
It is difficult to please all with one design.  Each to his own - you 
will have to weigh the pros and cons of each when reaching your own 
decision.  There are transceivers out there with large front panels, so 
if that is the most important parameter on your list, then one of the 
larger radios would be the first choice, but if receiver performance and 
diversity reception are the highest items on your list, then the K3 
shines without equal (despite any other 'shortcomings'.

73,
Don W3FPR

[Elecraft] K3 how often do you use it?

[Randy Downs]

Sorry for the misspelling in the original message. It should have
started "A fellow". He told me that a "Big Gun" would never buy a K3.
#1 due to not having 200w, #2 due to ergonomics. He basically said
that people that buy a K3 don't use it enough to not see the inherent
flaws in the layout, size etc. of the K3. He felt the 1000d was much
better. I don't own my 1000d or MkII anymore. I did buy the K3's with
some reservation as far as it being more like  my 751a as far as
bandswitching etc. But after using the K3 for over a year I have found
very few things to complain about. My Ft-2000 sure was prettier
though. Anyway I thought after being on this reflector for a long time
now that most people here were obviously pretty sharp, and use there
rigs quite a bit. I am not a contestor but I would guess those that
are have the basic requirements of a station with the antenna being
the number one concern, if not determination..
I've always found that the antenna was the most critical part of my
station. Then the transceiver as far dynamic range etc. Then power
output, in that order. What does everyone else think? I know looks to
a lot of people are #1, but I'm sure that the station I am trying to
contact really doesn't care.

Re: [Elecraft] K3 how often do you use it?

[Ci Jones]

Same here, but about 25 hours a week. Having sold an Orion and bought 
the K3, I did it in part because of its nice size and ergonomics. I 
love this radio, and I have only had it about a month now. But I guess 
I am weird in that I still really like my K2...

I use my K3 probably 30+ hours per week and I find it superbly suited

Re: [Elecraft] K3 New DSP Replacing

[O. Johns]

Hi John,

No, they don't.  I used a suggestion made earlier on the reflector and looked 
at the instruction for adding a grounding wire to the front panel microphone 
jack.  It is "Front_Panel_Microphone_Grounding.pdf" and can be found on the 
Elecraft web site in the page named "K3 Alerts, Enhancements and Application 
Notes."   To do that mod, you have to remove the front panel and the DSP board, 
so it guided me.

Re: [Elecraft] K3 how often do you use it?

[Gary Smith]

If I would have been the one to decide on size, the height is just 
fine with the bail up. I would have made it maybe an inch wider for 
increased accessibility for my thick fingers which are marginally 
thinner than my head. 

I'm the kind of who finds cell phone keypads too small too...

As to K3 use/week: 100% of my operations till I finish replacing all 
of the electrolytics in my Corsair II with new Ultra low ESR caps & 
even then it'll be 95% K3. 

Time wise? contests... most of the contest. 
DXing: Listening 10 hours a week. Transmit? 30 minutes including 
exchanges & small talk.
Other: 1-2 hours as my AM radio in the shack

[Elecraft] [K2] K2 PC Interface for N1MM

[Tom KG3V]

I need to connect my K2 to a PC using N1MM contest software, mainly for CW
use. I was getting ready to build an interface for a parallel port when I
saw that others have had timing problems and had to use something like a
Winkeyer interface instead. I don't want to bother building an interface if
the timing will not be acceptable. Anybody on the list have experience with
this?

Thanks and 73,

Tom, KG3V

Re: [Elecraft] K3 how often do you use it?

[Mike]

I didn't find any questions about marketing when I took my ham exams. I 
think all that needs to be judged on the subject, is to look at sales vs 
the time the K3 has been in production. Seems to me they're listening to 
the crowd who's willing to reach for the hip pocket. How much smarter  
marketing strategy could there possibly be?

I think HF in general is falling in popularity, but that's due to the 
FCC;s decision to put everybody's shack on their belt.

I do think the Kenwood TS-2000 is a particularly ugly radio. ;-)

Re: [Elecraft] K3 how often do you use it?

[James Sarte]

I use my K3 at least once a week... perhaps a few hours here or there.  I
have two kids and work full time, so getting the air time is a nice treat.  

I wouldn't mind having a bigger box with bigger knobs and a nice LCD to
boot, but my desk/shack won't permit it.  See my shack picture on QRZ if you
want to see how we New Yorkers in apartments deal with space issues, hi!

Re: [Elecraft] Using SDR-IQ with K3?

[Mike]

It's not difficult in that it's an assembly process, where you're 
screwing things together and plugging pre-assembled boards together. 
When I opened my kit, I was agog at the number of pieces there were. 
It's very gratifying to see the pile diminish.

Sort the screws, nuts, and bolts, and spacers carefully, by size. Some 
of them are very close to the same size.

Take your time, read each manual section thoroughly, then again, take 
your time, check off each item you've completed.

Use an antistatic mat and wristband.

Enjoy a great experience and a great rig!

[Elecraft] K3 how often do you use it?

[Randy Downs]

I fellow said "Elecrafts ergonomics and packaging is not appealing enough for 
most people despite its receiver performance. They could fix it by putting the 
K3 into a bigger box with a decent front panel and more knobs, but they wont. 
They wont because they are listening to the wrong people who dont have a clue 
about marketing and who dont understand the psyche of most everyday hams. 
Hedging your bets on a small group of hams who turn their radios maybe 5 times 
a year while ignoring those who use a radio probably every second day is not 
wise."
in a message to me. I guess now the question becomes, how often do you use your 
K3? I use mine at least 10 hours a week. We need a poll I guess.

Okay, for better or for worse, I think we're all set to go. The files are 
up, and our gracious web host Hector AD4C has the files in the same 
directory as last time:

http://www.ad4c.us/Elecraft%20K3/shared%20files%20from%20K3%20users/W6LX%20recordings_/

which is a shared folder that he has made available for things like this. I 
encourage you to contact him if you want to store similar files. My deep 
thanks to Hector for helping out.

This time, there are four recordings. Once again, all four receivers were 
set to 500 Hz (nominal) bandwidth centered at near 550 Hz, RF gain at 
maximum, no preamp, taken straight from the headphone output. The recordings 
are of 40 meter band noise at night as heard near Los Angeles where it was 
82 degrees yesterday and I barbecued dinner outdoors. :^)

One last thing... I'm getting a lot of resistance from some folks against 
doing this in this way. My response is simple: if you object to the way this 
test is being conducted, don't participate. All I'm asking is that you let 
the test run its course and at the end of it, you guys can exchange any and 
all transforms and analyses on the audio files you wish. That's all.

Hi All,

Good initiative to do "blind tests" :-)
I only thought that quite a number of people had "noise problems"
specifically listening to voice modes.
Would it be an idea to also make a test with SSB noise samples?

Excellent responses, I have about 15 reports in so far.

I think you're going to love reading some of these reports. Plenty 
of surprises. Not what I expected at all.

Anybody else want to take a stab at which is the K3 or want to change their 
vote?

[Elecraft] RF gain settings

[Gary and Kathleen Pearse]

Low Band experimenters might try using PRE and ATT enabled together.  
In order of increasing RF gain I find my settings are: ATT on, both  
ATT and PRE off (= normal), ATT and PRE on together for a modest gain  
increase, and PRE on.

On 160M with weak DX, depending upon the noise floor, it often makes  
a difference for me to kick up the gain just a little to better hear.  
Sometimes enabling the PRE alone results in too much gain and noise  
regardless of the RF gain setting.

I prefer running with the AGC off and adjusting the RF gain for weak  
DX. A congested contest or strong adjacent signals may require a  
different technique.

Re: [Elecraft] K3 New DSP board installed

[Steve Ellington]

I can't comment on the TX side since I never use it except for a little 
digital work. Also I have not seen any spurs. The headphone volume is the 
only major change I've noticed. You would probably need two K3s with old and 
new boards to really pin down what the differences are.
Right now I'm listing to the NA test on 40m in LSB mode with the filter set 
at 4 Khz. The dynamic range of this rig is amazing. I can copy a dozen 
different stations simply by tuning my ears!

[Elecraft] K3: Installing 100 watt PA

[Phil Hystad]

I am installing the 100 watt PA in the K3.  In fact, I just finished and the 
only steps are replacing the top and bottom cover panels.  There is the step 
where you place the PA board in place mating the two connectors to the KPAIO3 
board.  This is covered in the top part of page 16 of my KPA3 installation 
guide.  I had no problems with this step and I finished it up by putting the 3 
screws into the rear shield per the instructions.

Question: after I finished I was looking from the rear and noticed that threw a 
little hole (looks like one of those standoff mounting holes in the PCB) in the 
KPAIO3  just to the right of the left connector, I can see a toriod wound 
inductor that is mounted on the underside of the KPA3 and it looks like it is 
right next to the inside of the KPAIO3 board, likely touching.  I know that 
this inductor wire is insulated but is this the normal circumstance?

I hope I explained this question well enough.

73,
phil, K7PEH

Re: [Elecraft] K2 parts number questions

[Don Wilhelm]

Paul,

Parts manufacturers often put extra numbers in the designation, some are 
meaningful for the package configuration, but others are for some coding 
used by the manufacturer.  Just go by the last 3 digits - that is the 
value code, 471 would be 47 followed by 1 zero, or 470 ohms.

On the capacitors, 2.2 and 2R2 are the same as are 3.3 and 3R. - the R 
is often used at the place a decimal point would be located.

There is a variable C22 on the Control Board, but the C22 capacitor on 
the RF Board is fixed capacity.  I hope you are inventorying the 3 
boards separately because there is overlap of the part designation on 
the 3 boards (in other words, there will be 3 different R1s, 3 different 
C1, 3 different RP1s, etc.

73,
Don W3FPR

Re: [Elecraft] K3 New DSP board installed

Is the spur at 3.9 KHz gone?

The installation of the Rev D DSP board went smoothly. I updated the 
firmware and all is well.

The first thing I noticed was how much louder the headphones (Bose 32 ohm) 
are. I use the FP jack. The difference is huge. Before the upgrade, I ran 
the CW sidetone at 38. Now it's at 14! I'm not sure about the speaker volume 
but I don't believe there was much if any change.

I don't
 hear any change in the low frequency audio. It had already been 
improved earlier with one of the FW updates. Headphone impedance can affect 
this too.  Using MixW, I can see a well defined null in audio level below 50 
Hz.

The 3rd harmonic is still present in the low level audio output. This has 
bugged me from day one on the K3. It's weak but visible on the waterfall. 
See the photo at
http://n4lq.webs.com/apps/photos/photo?photoid=65288758 Don't bother telling 
me it's my sound card or my level is too high. I've already been trough that 
routine.

As for audio quality and listener fatigue, time will tell. This radio is 
such an improvement over my IC-7800 that anything I say is just nit picking.

Was the upgrade worth the money? I guess it depends on how you feel about 
money and your K3.

[Elecraft] K2 parts number questions

[Paul Huff]

I just finished an inventory of my K2 and I have a couple of quick questions.

1)  For several of my SIP resistor packs, my part has an extra "C" in the 
number.  For example the manual will give the number as "770103471" and my part 
is "103C471."  Am I correct in assuming that these are the same?

2)  I am more puzzled by a couple of capacitors that I have in the kit and a 
couple listed in the RF board parts list.  I'm not sure that they match up:

- The parts list gives C33, 2.2 pf, NPO, "2R2" or "2".  I have a small orange 
disk with a black tip that says "2.2".  Are these a match?

 - The parts list gives C22, ??? pF, NPO, "2R7", "3", "3.3", or "3R3".  (The 
value in the manual is not printed correctly, but I think it's supposed to be 
3.3 pF.)  I have a small blue cap that says "2.7C" on one side and "1 A" on the 
other.  Are these a match?

BTW, "C22" is also used to designate a variable capacitor, but I think that 
this 
"C22" is a fixed value in the 20/30 meter band-pass filter.

Thanks in advance for any help that you can give!

Paul - N8XMS

Re: [Elecraft] K2 setting KAT2 to bypass, display SWR

[Don Wilhelm]

Eric,

Sorry, I misunderstood.
The K2 bargraph LEDs show only a relative power scale - they never can 
indicate SWR.  The SWR display during a TUNE operation will appear on 
the K2 LCD display.

You will not see the SWR displayed during normal operation.  If that is 
what you want, you will have to modify your K2 to install an SWR meter 
between the K2 and the KAT2 input cable - but I would hesitate to do 
that because if the SWR meter is accidently not attached, you could 
inadvertently operate the K2 without a load, and that is not good for 
the health of the K2.

In any case, if you are talking about the KAT2, CAL S should show the SWR.  If

that is an indication that the bridge is not balanced - re-do the CAL n

Pout shows forward power and reflected power.  In this setting, if the SWR is

[Elecraft] New K3

[Jim Brassell]

K3 Serial No. 3813 joins K3 Serial No. 2783 on my radio desk.  The 3813 K3 
shipped from Aptos (or thereabouts) this last Monday.  It has the LPF mod and 
the new DSP board.  Please understand that I have significant high and low 
frequency hearing loss due to lots of loud noises in a past life.  I wear 
hearing aids which do a pretty good job of getting my hearing up where normal 
people hear.  Not the acute hearing types, though.  So, my observations on the 
audio of the two radios are totally subjective and not the least scientific.

All that said, I cannot tell any difference in performance and audio response 
between 3813 and 2783.  But then, I am one of those who never heard the DSP 
artifacts in the first place.  Both radios are running the latest production 
release.  I live in the country, so the NB does not get much use.  The NR, on 
the other hand, gets a pretty good workout.  I got hooked on DSP noise 
reduction with an Orion some years ago.  I can tell little, if any, difference 
between the two K3s.  The 3813 radio may be just a little quieter with the NR 
setting of 'F 1-2'.  Looking at both radios now, I notice that the volume 
control (main and sub) are set to pretty much the same place on both radios.  I 
will say that Don's suggestion in a posting related to AGC parameter settings 
really made a whumping difference in my 2783 K3.  He suggested an AGC slope of 
2 and a threshold of 8.  If you are having bumby AGC action and reduced volume, 
try those settings.  Works great on both the K3s.

I have ordered the DSP board upgrade and the LPF mod.  I did so just to keep 
the 2783 radio current.  That new hardware may become important in the future.

I replaced an FT-2000D with all the PEP updates with the 3813 K3.  The Quadra 
went, too.  An Expert 1K-FA amp will be delivered Monday.  With that amp and 
two K3's, I've got the best of DX'ing and contesting environments, less 
antennas, that a small pistol can have.  I'm working on the antenna situation.  
A 40 Meter four square begins the improvements in that area.  See you in the 
pileups.

73 and HNY

Re: [Elecraft] RX Test (long)

[David Christ]

As I recall it was RCA at the dawn of HI-FI who did a test using a 
live orchestra and a physical passband filter  to garner listener 
response.  The audience did not know whether the filter was in or not 
The results were that people found the orchestra without the filter 
sounded unnatural.  Their conclusion was that people had become so 
used to listening to the limited frequency response of the radios of 
the day that the real thing did not sound right.

Caveat:  That is my recollection.  If I remembered wrong it still 
makes a good story.

 Date: Mon, January 04, 2010 
9:12 pm To: KC2VNI  You might consider going with a 
G5RV antenna as a "starter" antenna.  It's multiband...80 meters and up to 
I think 10 meters...your rig has the auto-tuner so any minor matching 
adjustments will be handled by the tuner just fine.  There's no real 
challenges with the antenna.  It's not the "best" antenna in the world, 
but it will work very well as a simple starter antenna (people have worked the 
world with them), especially if your tree is high enough.  I assume you 
have 1 tree?  If so, then I'm assuming you'll run this in an inverted-vee 
configuration (center up high as possible, ends slope down from center at a 30 
to 45 degree angle).  The inverted-v is a little more omni-directional, 
which again is good fo
 r a starter antenna.  I think key is getting the center up as high as you 
can.  30 feet?  40 feet?  Again, as much height as you can will 
help (in general). If you are pressed for space, then you can always consider 
the G5RV jr.  It's shorter in length, requires less height, but it only 
runs 40 meters and up (40 - 10). I believe MFJ has a G5RV.  If not, 
there's plenty other vendors that do.  One's pretty much as good as 
another.  The G5RV is simple enough that you could probably even make one 
yourself... I can't comment too much on the batteries, other than to say I know 
of people powering their rigs using car batteries and golf cart batteries... 
Good luck and welcome to Amateur Radio! 73, Dave K6DCH On Jan 4, 2010, at 3:19

[Elecraft] [K3] RE: New K3 User and New Ham

[KC2VNI]

Mike: I don't have any form of power supply. From my brief discussion with 
the tech over at Elecraft, he recommended the RS-35A from Astron. 
  
In this instance, I did look at the Western Mountain Radio unit you have 
below. 
  
I wanted to make sure I understand something: that the radio can be 
supplied from 120VAC from this unit OR you can use it to supply power from 
an external battery as you mentioned below. 
  
Is this the case? 
   
  

 Original Message  Subject: Re: [Elecraft] New K3 User and New 
Ham From: "Mike B-12 [via Elecraft]" 
 Date: Mon, January 04, 2010 
9:26 pm To: KC2VNI  Good evening, Steve.  As for 
item #2, you'll likely find that even with a 100 AH battery, the voltage will 
drop rather quickly at 100 watts. And as the voltage drops, the current 
consumption will rise to keep the output the same, even more rapidly draining 
the battery.  I would suggest: 1) consider using lower power. You'll 
likely find that running at 50 watts (or less, particularly on CW or PSK) will 
net you essentially the same number of QSOs, at far less power consumption. 2) 
run 2 batteries in parallel (in this case, 12 volt batteries).  That will 
help keep the voltage up by spreading the load across more than one battery. 3) 
even if running parallel batteries, consider a battery booster from MFJ or 
http://stores.tgelectron
 ics.org/StoreFront.bok   I have not tried either, but I think QST did a 
review of 2 models some time back. By far the easiest (and most common) type of 
large battery to use is a sealed lead acid.  Technically called 
Valve-Regulated Lead Acid, but more commonly called "gel cells" or AGM 
(Absorbed Glass Mat).  While there are slight charging differences between 
gel & AGMs which need to be observed, for our purposes here either will 
work the same.  These are NOT automotive batteries, but rather true deep 
cycle batteries.  Perhaps you already know this, but automotive batteries 
have many, thin lead plates that give a lot of surface area.  This is 
great for sudden, short periods of high current draw, like starting your car, 
but very bad for long-term discharge (like leaving your headlights or radio 
on).  True deep cycle batteries are essentially the opposite, made with 
fewer but thicker lead plates, and generally poor at very high current di
 scharges, but great at running smaller loads long term. Some AGM batteries on 
the market now will work as starting batteries, too, but that's not relevant 
for our needs. If you're on a tight budget, a car battery will work at low 
power for a while, but you'll quickly want a better battery.  The 
batteries labeled as "deep cycle" at the big stores generally are NOT deep 
cycle - it's just marketing.  You'll likely have to go to a real battery 
store, though the some of Optima line of batteries are deep cycle, and can be 
found at Sears, among other shops. The gel- & AGM-style batteries are 
sealed to the point where you can't add water, but if over-charged will vent 
gas.  However, with a quality charger, this is a non-issue and these 
batteries are approved for in-home use (think electric scooters and 
wheelchairs). This is an example of a quality, American-made AGM battery: 
http://www.sunxtender.com/   We've used these at work for our remote 
weather sites fo
 r the last 5 years or so, and have been quite happy with them (no financial 
relation, yada yada yada).  The PVX-1040T size is one we use; it's rated 
at around 100 AH (at a 20-hour rate), and tend to cost around $230.  Not 
cheap, eh?  There are less expensive brands out there, typically made in 
China.  I have zero experience with these. This is a long email (sorry), 
but food for thought.  There are lots of battery choices out there, but 
since you've picked the top rig, I thought I'd show you one of the top 
batteries ;-)  Once you've got your batteries picked out, get a quality 
charger.  There's no better way to destroy any battery than to cook it (or 
chronically under-charge it) than with a crappy charger.  I'd even venture 
to say that if you want to save money on batteries now, put the money towards a 
good charger - it will outlast at least a few sets of batteries. If you already 
have a power supply, or simply as another option, West M
 ountain Radio's Super PWRGate works well ( 
http://westmountainradio.com/SuperPWRgate.htm ).  It needs a power source, 
but has a charging circuit and essentially works as an uninterruptable power 
supply for your rig.  I bought one 3 or 4 years ago, and it's done a great 
job of maintaining my batteries. 73, Mike KW1ND

Re: [Elecraft] K3 not communicating with PC

[Wes Stewart]

The reason I mention this is that I recently went through a similar 
troubleshooting exercise with a KRC2 where it was suggested that my USB->serial 
device was bad, I should use the K3 AUX connector rather than RS232, I needed a 
real serial port, etc. etc.

After jumping through all of these hoops, the end result was that it was an 
Elecraft software problem.

Wes,

No-one is holding the K3 blameless, but in the interest of complete 
troubleshooting, it is quite reasonable (to me) to check the easy things first 
if for no other reason than to eliminate them from the suspect list.  It is 
often that the things that are most frequently overlooked are the culprit.  
Despite the fact that these things are easy to check, human nature tends to 
expect the worst - elimination of items from the suspect list as a first order 
of business is always a wise undertaking in troubleshooting procedures.  In 
other words, proving what works is just as important as finding what does not 
work.

73,
Don W3FPR

A few questions about the K144XV...

1.  I noticed from the manual that the chassis stiffener that comes with the
K144XV seems to be the same one that I already have in my late model K3
(3799).  Is this true?

2.  Although I can look it is easier to ask:  would it also be true that the
need to solder in a new power connector to the RF board, or would that also
be already on my late model K3?

3.  Is there a waiting queue?  If I ordered now, about how long until
delivery?  In my case, I won't be able to get to it until February but I was
curious if the waiting list is longer then that in which case I would order
right away.

Re: [Elecraft] New Test

[pd0psb]

Hi All,

Good initiative to do "blind tests" :-)
I only thought that quite a number of people had "noise problems"
specifically listening to voice modes.
Would it be an idea to also make a test with SSB noise samples?

This time, there are four recordings. Once again, all four receivers were
set to 500 Hz (nominal) bandwidth centered at near 550 Hz, RF gain at
maximum, no preamp, taken straight from the headphone output. The recordings
are of 40 meter band noise at night as heard near Los Angeles where it was
82 degrees yesterday and I barbecued dinner outdoors. :^)

Re: [Elecraft] RX Test (long)

[Guy Olinger K2AV]

I agree.  These artificacts have "sidebands" that increase and
decrease with content in the normal passband, but their separation and
frequency span is as if the frequency content (not the amplitude) of
the normal passband were divided by 2 or 4.  They are way down, and do
not exceed the amplitude of the 7.8 and 12 artifacts.

73, Guy.

[Elecraft] K3 New DSP board installed

[Steve Ellington]

The installation of the Rev D DSP board went smoothly. I updated the 
firmware and all is well.

The first thing I noticed was how much louder the headphones (Bose 32 ohm) 
are. I use the FP jack. The difference is huge. Before the upgrade, I ran 
the CW sidetone at 38. Now it's at 14! I'm not sure about the speaker volume 
but I don't believe there was much if any change.

I don't hear any change in the low frequency audio. It had already been 
improved earlier with one of the FW updates. Headphone impedance can affect 
this too.  Using MixW, I can see a well defined null in audio level below 50 
Hz.

The 3rd harmonic is still present in the low level audio output. This has 
bugged me from day one on the K3. It's weak but visible on the waterfall. 
See the photo at
http://n4lq.webs.com/apps/photos/photo?photoid=65288758 Don't bother telling 
me it's my sound card or my level is too high. I've already been trough that 
routine.

As for audio quality and listener fatigue, time will tell. This radio is 
such an improvement over my IC-7800 that anything I say is just nit picking.

Was the upgrade worth the money? I guess it depends on how you feel about 
money and your K3.

[Elecraft] New Test

[Al Lorona]

Okay, for better or for worse, I think we're all set to go. The files are up, 
and our gracious web host Hector AD4C has the files in the same directory as 
last time:

http://www.ad4c.us/Elecraft%20K3/shared%20files%20from%20K3%20users/W6LX%20recordings_/

which is a shared folder that he has made available for things like this. I 
encourage you to contact him if you want to store similar files. My deep thanks 
to Hector for helping out.

This time, there are four recordings. Once again, all four receivers were set 
to 500 Hz (nominal) bandwidth centered at near 550 Hz, RF gain at maximum, no 
preamp, taken straight from the headphone output. The recordings are of 40 
meter band noise at night as heard near Los Angeles where it was 82 
degrees yesterday and I barbecued dinner outdoors. :^)
 
One last thing... I'm getting a lot of resistance from some folks against doing 
this in this way. My response is simple: if you object to the way this test is 
being conducted, don't participate. All I'm asking is that you let the test run 
its course and at the end of it, you guys can exchange any and all transforms 
and analyses on the audio files you wish. That's all.
 
Reminder: To cut down on reflector traffic, respond to me privately.

Good luck,

Al  W6LX

Re: [Elecraft] RX Test (long)

[Larry - K2GN]

Noise or no noise vs opertional ability to hear.
For me the K3 and it's DSP, NR and NB has help me over come the hearing 
problem of being old and with teninous. The tone in my ears is so bad that I 
could NOT pass the CW requirement test for an extra class license. My 
previous radios with all the filter and DSP did not help.
The tone in my head is verified at 1150Hz. It made coping a signal that was 
in normal noise very difficult. It resonanted with my internal tone at about 
15WPM.
I've used one or the other CW encoding programs for years.
I now find that with the K3 CW is getting easier to copy.
I'm looking forward to the Rev D and expect further improvement.
Maybe I'll be able to get rid of the encodeds soon

Look for either:

(a) a small piggyback board on the back of the DSP board near the 
speaker amplifier IC (U1, at the upper left corner of the PCB as you 
face it in normal orientation with the component side of the board 
facing you, or

(b) an IC (U30) and a number of components surrounding it to the right 
of the speaker amplifier IC (U1).

Note that Rev D refers to the "assembly level" of the DSP board, *not* 
the raw PCB revision level.

If you are still uncertain, after you receive your new DSP board 
assembly, send me a private email with photos of both  sides of the DSP 
board and I'll let you know if it is equipped with the LPF or not.

Re: [Elecraft] K3 New DSP Replacing

[James Sarte]

How can we ensure the LPF is there once we receive our rev D boards?  That
little LPF is the only reason why I upgraded, and I'll be knackered if I get
a DSP board that doesn't have one.

Cheers!

No instructions included.
I've also been told that the production version of the Rev. D board doesn't 
have the little add-on LP board and that those components are now built in 
to the main DSP board. I have not verified this but it does make sense.

[Elecraft] Fine Tune Frequency Readout K2

[Dean Fewkes]

I am looking for the simplest method to fine tune the frequency readout on my 
K2 using WWV. It reads about 60 hz high right now.

Thanks for your help!

I suspect this is more of an N1MM Logger question than a K3 question. 
Here are some first stabs at it, but for follow up you should perhaps be 
asking this question on the N1MMLogger-Digital group at Yahoo.

In your last sentence, I presume you meant FSK D and not PSK D. N1MM 
Logger does not support PSK D. In PSK D, all you will get when you 
transmit from the Logger is an unmodulated carrier. Also, MMVARI does 
not support FSK, so if you are using the MMVARI engine with the K3 in 
FSK D, again all you will get is an unmodulated carrier on transmit. To 
use FSK D from N1MM Logger, you need to use the MMTTY engine and supply 
an on-off keying signal to the K3's FSK input. From your description, 
you are using the sound card to provide the modulation, and AFSK A is 
the mode you really want to use.

For AFSK RTTY using either MMTTY or MMVARI, you need to ensure that in 
N1MM's Configurer under the Mode Control tab you have mapped RTTY to 
AFSK for both DI windows. If you map it to RTTY, the K3 will be in FSK 
D, which won't work for you. Check this by looking at the mode in the 
title bar of the entry window and in the band amp; it must read AFSK.

When you say you can only key the radio via MMVARI, what do you mean by 
"key"? Do you mean switch the radio to transmit, or do you mean get 
non-zero output?

If it's the former, there is a problem with PTT. If you are using PTT 
via radio command or via RTS on the radio control serial line, you do 
not need to check any of the "Digital" boxes in the configurer, but if 
you are using a separate serial port, you need to check the "Digital" 
box for that port, click on the "Set" button and set the "Dig Wnd Nr" to 1.

If it's the latter, I suspect that the problem may be a mode mismatch - 
see above.

I'm off to another location now for a contest, but I'm sure there are 
other people who can help you either here or on the N1MMLogger-Digital 
group.

Rich VE3KI

I see 7.8 and 12 KHz products clearly at about 10 dB above the 
stopband noise with no signal present.  They get much stronger 
with signals present and additional products appear.  Even 
though the maximum level is still 60 dB below the listening 
level, they are still clearly above the "masking" level and 
they will be audible to someone with normal hearing with 
"full range" headphones and/or speaker.

Re: [Elecraft] K2 setting KAT2 to bypass, display SWR

[Don Wilhelm]

Eric,

Please clarify, There are no LEDs on the KAT2, but the external KAT100 
does have LEDs. (The mind does get 'fuzzy' at 4 AM).

In any case, if you are talking about the KAT2, CAL S should show the 
SWR.  If it does not indicate SWR correctly, and the SWR changes with 
the power level, that is an indication that the bridge is not balanced - 
re-do the CAL n procedure to correct.

Pout shows forward power and reflected power.  In this setting, if the 
SWR is other than a perfect 1.0 match, there will be some reflected powr 
and it will vary with the power level.

Don W3FPR

No, the low stopband noise with (relatively) high levels of 
DAC leakage products is what makes the receiver tiring.  

It's the additional "noise" is in the 1000 - 3000 Hz range 
(with CW filter) that can be eliminated by reducing the RF 
gain that makes the receiver "noisy."

Re: [Elecraft] RX Test (long)

[Guy Olinger K2AV]

I think the noisy issue derives out of our quite old analog listening
habits and expectations.

I would estimate for easily half of the reflector population (my real
guess is 75%), that their listening to radio career began with an
analog HF radio that didn't have enough gain to present ambient
antenna noise over receiver noise except on the lowest bands.

Without exception, these were tube radios whose circuits didn't
flat-top overdrive, just round it off, and whose audio transformers'
response gradually died over 4 khz. There were no sudden transitions
in any of them save the few lucky enough to have a crystal filter for
narrow reception on CW.

As another has stated, the sharp limits of selectivity, vast extents
of audio response, and enough receiver system gain to bring anyone's
10 meter outside ambient noise up to full audio,  were ideals, frankly
just not attained, or in some modern radios curiously avoided (knew
something?).

Quite a lot of posted complaints here had at their roots one single
issue: on the lower bands,  a typical metropolitan area RESTING
outside ambient noise level is S2 S4 and S8 on 40, 80 and 160 meters.
In the K3 attenuator off, preamp on, and RF gain at full results in
ambient noise fully engaging the AGC and remaining at full audio on
160 through 40 and possibly on 20 as well.

If RF gain is full, and preamp is on, the receiver is set to present a
quarter microvolt as full loudness, and anything higher than that
REDUCED to full loudness.  This means that outside ambient noise on
160 will always be at full loudness, and also at full "shrill" given
the wide audio response.

This was the first complaint about our contest group's first exposure
to an Orion, and for all practical purposes the ONLY one.  Nothing in
second or third place.  Once we knew we had to PURPOSEFULLY REDUCE the
receiver gain (settings for preamp, attenuator, RF gain)  for the
lower bands to reduce the outside ambient noise to 1/4 full volume,
the Orion became imminently superior to the MP's we were using at the
time.

This remains true with the K3, even though some stubbornly continue to
insist they shouldn't have to reduce the RF gain. With the Orion,
those settings (including the RF gain) could be remembered by band.
Many Orion users will tell you that the RF gain, once set moderately
for their locale's ambient noise per band, is never touched again.  In
effect it was "calibrated" to their local noise. Remembering ATT and
PREAMP by band is close to the Orion's flexibility.

On my K3, to set 160m ambient noise in a 500 Hz bandwidth to 1/4
audio, I have to turn off the preamp, turn on the attenuator, and
reduce RF gain to 2 oclock.  Then it's just as quiet as my ancient
tube analog receiver.

The discussion about fatiguing audio becomes a completely different
subject, once proper reduction of gain to match ambient noise is taken
care of.

73, Guy.

Re: [Elecraft] N1MM RTTY & K3

Terry,
I just went through something similar. Make sure the MARK frequency in 
MMTTY (which N1MM uses) matches the mark frequency in the K3. In data 
mode, hold the PITCH button and you see mark and shift.

ALso make sure that MMTTY is set to use the soundcard (Options, Misc).

Re: [Elecraft] RX Test (long)

[Milt, N5IA]

H

I suppose I am in the category where my hearing is "impaired".   At least my 
wife informs me near daily that such is the case.

I was the oldest of the 13 operators blessed with 7 early production K-3s to 
perform a task nearly identical to that described by David.  The two 
youngest operators (one just recently married at that time) as well as the 
majority of the VP6DX DX-pedition crew are among the elite of current 
contesters.

Thirteen opertors taking care of SEVEN operating positions 24/7 for nearly 
17 days; non-stop, day and night, three modes, Topband through 10 Meters, on 
an uninhabitated atoll with generator power was the task.

The results speak for themselves; both for the operators and the equipment 
employed.

I did not and have not ever heard any of the other 12 operators mention 
anything about the perceived noise problem.  Suffice it to say that 
apparently the "noise" does exist for some small percentage of K-3 users 
with very acute hearing.

BUT, my point is that there was NOT a problem with this "problem" for the 
very wide range of age and capabilities of the VP6DX team.

Likewise, I have never perceived such an annoyance or distraction with my 
personal K-3, or other K-3's that I have operated.  There is a difference of 
some subtle manner re the transceiver RX "sound" that I had been used to 
with the name brand and model radios I had used for the previous 13-14 
years.  But it certainly is not detrimental; in fact I can say that it is 
advantageous to ME.

That is my observation and report, and MHO.  Happy New Year to all.

Milt, N5IA

[Elecraft] Using SDR-IQ with K3?

[Mike Tatum]

Hi All,

I am about to order my K3 Kit and want to make sure I am ordering the  
right part to enable
me to use the SDR-IQ unit with my K3.

Can someone please confirm that to get the correct IF Output for the  
SDR-IQ I need to include the
KXV3A module with my K3 Kit order?

If I've misunderstood and have detailed the wrong item please educate  
me!

Many thanks and a Happy New Year to all!

Mike.

Re: [Elecraft] K3 New DSP Replacing

[Steve Ellington]

No instructions included.
I've also been told that the production version of the Rev. D board doesn't 
have the little add-on LP board and that those components are now built in 
to the main DSP board. I have not verified this but it does make sense.

I wasn't really worried about taking it apart. I was just surprised
that Elecraft didn't include instructions given what comes with their

Re: [Elecraft] RX Test (long)

[R. Kevin Stover]

I suspect that's about it in a nutshell.
People have gotten used to listening to a certain level and quality of 
noise from the YaeKenIcom crowd that when presented with a receiver this 
good they are convinced it's "noisier". Noise, which used to be covered 
up or attenuated by phase noise or other crud in the other rigs isn't in 
the K3.

People simply haven't been hearing true reproductions of band noise 
etc... with the other rigs.

My own pet theory.

Re: [Elecraft] K3 New DSP Replacing

[Mike Harris]

G'day,

It's not exactly rocket science, you take the front panel assembly 
off, remove a board and replace it with the new one, replace the 
front panel assembly.

The assembly manual covers the front panel work or maybe just 
download the DVR installation manual it's got all the information 
you need for taking off and replacing the front panel and more. 
However, having said that even the relatively trivial upgrade of the 
digital I/O interface came with the usual pages on how to take the 
top off but there was also some track cutting.

The other day we had a request for an instruction to click on a 
button in the K3 utility that was clearly marked with its function. 
It seems these days that hands need firmly holding.

Regards,

Mike VP8NO

[Elecraft] N1MM RTTY & K3

[terry burbidge]

Perhaps someone can please help. I previously set up N1MM to work RTTY via
N1MM digital interface using LSB mode on my K3 - no problems there. The K3
User Manual suggests using 'Data - AFSK A' mode for soundcard based RTTY
which I have tried to do. In AFSK A mode on the K3, I can only key the radio
via MVARI and not via the N1MM main window (F1-F12 macros). However, if I
set the K3 to 'PSK - D' mode, it does work from the main window.

 

 

Cheers,

 

Terry Burbidge

[Elecraft] K2 setting KAT2 to bypass, display SWR

[eric norris]

Gangue:

I am trying to set my K2 to bypass the internal KAT2 tuner and display SWR.  
When I set ATU CALS it shows the power out instead of SWR.  When I set ATU CALP 
I also get power out.  I am running the K2 into a dummy load through a 
wattmeter, wattmeter confirms SWR 1-1.  Even in ATU CALS the LEDs on the front 
panel vary up and down by the power out not the SWR.  WHAT AM I DOING WRONG?  
WHY AM I STILL PLAYING WITH MY K2 AT 4AM?

thanks and 73

Re: [Elecraft] RX Test (long)

[Barry N1EU]

Sorry, I don't buy the theory that the low-level stopband artifacts are
responsible for the perception of the K3 being "noisy".  To my ears and
tests I've conducted multiple times, the artifacts are audibly masked in
listening, even without the LPF.  

On spectrum analysis, I see artifacts in descending order at 12Khz, 18Khz
and 14.1Khz.  To make the strongest of these (12Khz) just barely audible, I
have to apply  a full 20dB of boost (via narrow parametric EQ filtering). 
Perhaps it can be argued that the artifacts are responsible for a subtle
sense of listener fatigue (I'm skeptical), but not the "noisiness" discussed
ad nauseum on the reflector.  I am convinced that "noisiness" is due to
improper gain adjustment.

73,
Barry N1EU

Re: [Elecraft] RX Test (long)

[David Cutter]

If the K3 is being used by a contest group or dxpedition, for instance, you 
will have a wider range of hearing sensitivities and these activities force 
us to concentrate a lot more and use a radio for long periods.  On this 
basis, fatigue due to these artefacts should be eliminated for the benefit 
of the group, particularly those listening to weak signals.  I think the 
extra filter would be a good investment.

Absolutely. It is easy to overlook the obvious. In problems of this sort the
most likely culprit is always software, followed by cabling.

It's a good idea to use the Terminal facility of the K3 Utility to test
communication. Try sending FA; and see if you get a frequency back. A common
problem especially with USB adapters is that data is corrupted. You may not
see this with a normal application as it will probably ignore the corrupt
data and behave as if it is not connected.

But these "artifacts", at least in my observation, are only present when a
signal is present. If they are there when only noise is being received, they
are below the extremely low out of band noise level. Therefore, whilst I can
see that they could contribute to unpleasant or tiring sounding audio for
those blessed with acute hearing, I can't see that they would result in the
receiver sounding noisy.
