Re: [Elecraft] The amp I would like to see Elecraft build.

I am going to use one of these HP switching 50v PS to supply my 
Harris TV amp conversion to 6m.  Several others are using this PS for 
this application.  Use of Ferrite cores filter switching noise:

Re: [Elecraft] The amp I would like to see Elecraft build.

FALSE.  CW is 100% modulation of a carrier by a rectangular wave, and 
that modulation, like ANY amplitude modulation, produces sidebands, 
which will excite distortion in a non-linear amplifier.  I don't know 
enough about Warren's Pure Signal system to know if it could be used on 
CW. IM sidebands can be clearly seen in the display of a CW signal on a P3.

SDR based predistortion are most effective if the individual stages
are as clean as possible.  That means 24/48V amplifiers for power
levels above 25 to 50 W and 60/100V devices for 500+W amplifiers.

Yes but CW (and FSK/RTTY) are dead according to the FCC and ARRL.
Now its all modes that require linear amplification over at
least 2.7 KHz.  Better get used to it!

The issue relates to voltage clipping and current saturation.  No
amount of predistortion is going to clean up square waves.

Re: [Elecraft] The amp I would like to see Elecraft build.

[Ignacy]

12 V PA would open a new type of portable operation. 
Call at 500W, conclude the contact at 100W or even 12 W if sufficient. 

Power for 500W short term could supplied by a few Li-ion batteries with
superconductors. Perhaps 3 lb total. 

No more frustration at a campground

But larger power brings new problems as antenna tuners are larger, and or
resonant antennas limit band coverage. 

Ignacy, NO9E

While making these changes would help, they pale in comparison to a SDR 
implemented pre-distortion system like Pure Signal. The big advantage will be 
that the entire transmit chain will be cleaned up as a system, rather than 
trying to deal with each box separately.

Time to move into the 21st Century.

Subject: Re: [Elecraft] The amp I would like to see Elecraft build.

I'm not always on the same page as Joe, but this time I could not agree more.
As someone who has measured the TX IMD of both my kit K3/100 and a factory built
K3S/100 I can attest to this.  First of all, they like every other manufacturer
and the ARRL fudge the numbers by 6 dB (in their favor of course) by comparing
one distortion product to the sum of the two tones.

EIMAC and MIL-Specs say, "The standard method of specifying the magnitude of the
distortion products is to specify the reduction in decibels of
one product from one tone of a two-equal-tone signal."

Elecraft isn't to be singled out for this, they are just doing what the ham
industry is doing.

One of several motivations for replacing a perfectly working K3 with the K3S was
the hope that the FET PA would be cleaner than the bipolar PA in the K3.  Big
disappointment.  One factor is the fact that it's still a nominal "12 V" PA.
Another is that it's still driven by a bipolar "10 W" exciter.  If some of you
are using a bare K3/10 and running at greater than 10 W, shame on you.  And
shame on Elecraft for letting you do it.  Based upon my measurements (which BTW
correlated to 1 dB or less with Elecraft measurements) the IMD of the 10W PA
above 10W is abysmal.

So, no higher power "12 V" PAs please!

Heaven help us, NO!  The 12V amplifiers are marginally clean enough

than -30 dB PEP.  What we really need is a 48V final for the K3/K3S

Re: [Elecraft] The amp I would like to see Elecraft build.

[Ron D'Eau Claire]

Dan, the issue is producing more than 100 watts from a 12-volt supply without 
unacceptable levels of IMD. That's why Elecraft used a 60-volt power supply in 
the KPA500. 

If the gain restrictions are removed, Elecraft (and anyone else) could produce 
a 500 watt amplifier that worked from an exciter with any level of drive, even 
less than 1 watt.

Then Elecraft can build us a 12 volt version of the KPA500.


Heaven help us, NO!  The 12V amplifiers are marginally clean enough
at 100W.  A 500W 12V amplifier is likely to have IMD be much poorer
than -30 dB PEP.  What we really need is a 48V final for the K3/K3S
(maybe at 200W) so we can see IMD in the -45 dB to -50 dB PEP range
where it really should be.

It's time to make a stand for cleaner signals ... not signals in the
same class as the "no name" Italian and Chinese amplifiers.

[Elecraft] Build, Rescue, or Service your Elecraft?

[Alan D. Wilcox]

Hello,

Have you always wanted an Elecraft? A KX1, K1, K2, K3, whatever? Does 
your K2 need a tuneup?

I build and service them all!

See what my clients have said about my construction and service work at 
http://www.eham.net/reviews/detail/6768


Photos of the popular Twins -- the KPA100 and KAT100 in EC2 enclosure 
--  are at

http://wilcoxengineering.com/kpa100-in-ec2/

In addition to tuning your rig, I can also rescue a building
project you might have started some time ago.

Cheers,
Alan

Normally my website at http://WilcoxEngineering.com has more details,
including photos of some of my Elecraft projects, but it was hacked
into several times. Yet another project: update from Joomla 1.5x to
new Joomla 2.5x. In the meanwhile, standby; I'll have it up again soon.

Elecraft work continues, so either call or eMail me directly.

[Elecraft] Build quality of K3 regarding control knobs and switches?

[tav58]

I was wondering what is the build quality as far as the controls go for the K3? 
Do the knobs and switches seem to be of high quality and feel? Especially the 
main tuning knob. I know it's a great radio overall, but I don't like wobbly 
control knobs. Thanks!

I don't know what you consider wobbly - I find the K34 knobs to be to 
my likeing, but since you have doubts, I suggest you go to a hamfest 
where Elecraft has a presence, and you can touch and feel the knobs for 
yourself before making a decision.

Yes, there have been some instances where the knobs would split and the 
concentric knobs were off-center, but those problems are being addressed 
by Elecraft and the defective knobs are being replaced at no cost to the 
consumer.

Re: [Elecraft] Build quality of K3 regarding control knobsandswitches?

I bought them also.  While there is nothing at all wrong with the 
perfectly adequate Elecraft stock knobs, the heavy aftermarket products 
*really* make the K3 feel like a million bucks.  Considering that the 
main tuning knob is the major interface between radio and operator, they 
are worth considering if you don't mind blowing big bucks on something 
you don't really *need* but rather simply *want*.  www.73cnc.com.

Re: [Elecraft] Build quality of K3 regarding controlknobsandswitches?

[Bob K6UJ]

I'm with Jim,  I like the original knobs. 
I also have the tension set at nearly zero on the main tuning knob.  It has 
just enough mass to give a little flywheel effect when needed 
for a quick spin up or down.  Perfect for my use.

 I didn't buy them and I won't.  I like the originals.  I tune by rolling my 
 fingertip around the outer edge of the knob to turn it so I apply almost no 
 pressure at all to the knob even turning it rapidly.  I set my tension to 
 nearly zero on the build as that is what I want.  Larger or heavier knobs 
 would be totally counterproductive for me.  I like the original look and 
 feel as well and do NOT want to mess it up the looks of my K3, everything 
 matches very nicely.

Re: [Elecraft] Build quality of K3 regarding control knobs and switches?

[Gary Gregory]

*Hmmm...No Name, No Signature, No call sign...but here goes..:-)

K3 #679 has what I would call very nice knobs and buttons etc. Mine turn
without any wobble as you said so all is good.

By way of interest, mine is carted around VK in a motorhome as a genuine
24/7 portable set-up and to date I cannot fault it.

Enjoy!

 Especially the main tuning knob. I know it's a great radio overall, but I
 don't like wobbly control knobs. Thanks!

[Elecraft] build # 6952 smoke! yikes

[John Fritze]

Before turning on power the resistance checks were all good.
Everything looked good, didn't see any problems.  The first 2 tests
went without a hitch, so perhaps I was a bit cocky.

I turned on the power to do alignment and test part 3, got a loud
snap, bit of phenolic smell

Not exactly what I would have liked to happen:-(   Q7 was toast.  I
thought that perhaps I didn't get the insulator on the screw properly
as it's a bit tricky. I also found I had inadvertently forgot to
install Z1.  So I put it in, and I replaced Q7 with one from the
second K2 kit, but no joy.

I basically now have a 12V short to ground:

Q7 collector 24.5 Ohms
Q6 base 118 Ohms- right where it was before
Q7 base 2 Ohms
U 10, 11, 12 are all as before.

Anyone have any thoughts before I just start pulling the surrounding parts?

Re: [Elecraft] build # 6952 smoke! yikes

[Don Wilhelm]

John,

You had a collector to base short (or leakage) on one of the PA 
transistors, which caused Q7 to draw a LOT of current and even explode.
That does not say that Q7 is the only problem.  Other potential 
candidates are Q8 and Q11 and Q13.

Q11 and Q13 set the bias for Q7 and Q8 - so remove both Q7 and Q8 and 
during transmit (or TUNE), measure the voltage at the Q7 or Q8 solder 
pads - if it is quite different from 0.62 volts, then you must find the 
problem (likely Q11 or Q13) before installing Q7 and Q8.

Secondly, Elecraft has recently been matching Q7 and Q8 for all kits and 
replacement PA transistor kits, so you should have replaced both Q7 and 
Q8 as a pair - you stated that you just replaced Q7, and that may have 
caused a secondary failure if the HFE of Q8 was quite different than the 
Q7 that you installed.  It looks like you now need 2 K2PAKITs to be 
certain of the matched transistors.

BTW - the K2PAKIT does contain replacements for Q7, Q8, Q11 and Q13 as 
well as new thermal pads and PA mounting hardware should that be 
needed.  There is also a replacement for R50 if that is needed too.

73,
Don W3FPR

 you are using Speech Processing does the DVR record the

 Also, when you playback a message from the DVR, does the

Which kit?

If it is one of these three I can build it for you.

- XG2 Three Band Receiver Test Oscillator / S-Meter Calibrator
- N-gen Wideband Noise Generator.(100 kHz - 500 MHz)
- 2T-gen 2-Tone Test Oscillator

Send me an e-mail if you are interested.

[Elecraft] build is not a noun

[Charles Harpole]

Please help the English language maintain some

little bit of coherence and do not use build as 

a noun, as in Did we do a build today?

Better and already established as English,

and not techno-speak, is Did you build it today?

Is Eubonics next?

Thanks so much,  73

Re: [Elecraft] build is not a noun - OT

[David Ferrington, M0XDF]

I would agree, but in the software world, build is a process or  
function and 'doing a build' is what you actually do to produce a  
program, sometimes the command is even called 'build'.
In this case, it might be argued that asking if 'we did a build today'  
is more correct?

It certainly 'feels' more correct in some cercumstances.

But then, if I was querying about a specific program, especially if it  
was causing problems, I might well ask 'did you build it today or  
yesterday'.


Personally, I'm not bothered about the change in use, it has gone on  
for many 100s of years and is the reason English is such a widespread  
and up-to-date language.


I had to look Eubonics up!

RE: [Elecraft] build time for KPA100

I found the KPA to go pretty quickly after I got the proper wheel for my
Dremel. You're supposed to take the anodizing off the heat sink in
specific places, and going at hard anodizing with a piece of emery cloth
made me go nuts.

The dremel attachment (a tiny wire brush) was great for taking the paint
off of the case where grounding was needed as well.

My build time for the basic K2 was about 45 hours. Build time for the  
KPA100 was about 8. I remember being surprised at how quickly it went  
together, and that it worked perfectly the first time.


Also, wondering about the KDSP2 (looks quick) and KNB2 (also looks

A couple of hours each.

[Elecraft] Build order

[Paul Mayo]

Hi All --

I am well underway, RF board part 2 has been tested and works fine.  Lots of 
signals on 40 meter. I am mid way through part 3 and have a question on the 
build order of the other options.  I will assemble and test the K2 completly 
before continuing by adding options.  I have the KSB2, K60XV, DSP and KPA100 to 
add. In what order should the options be installed and could some be combined ( 
like the DSPand the K60XV) to minimize assembly and disassembly.  Would you 
leave the KPA100 to last?

My skill level is moderately advanced (electrons in my blood/EE) plus a fair 
set of test equipment.

RE: [Elecraft] Build order

[Don Wilhelm]

Paul,

Build and test the KSB2 and the K60XV first - after those are installed, you
can do a complete alignment and calibration of the K2 and that alignment and
calibration will not be changed by the addition of the KDSP2 or the KPA100.

Those options which affect the base K2 alignment in some way (large or
small) are the KSB2 (filter alignment), K160RX (VCO and bandpass alignment),
and the K60XV (VCO and bandpass alignment).  The other options may be
aligned independently and do not change the base K2 settings.

Hi Paul,

I invite you to check out our website http://www.unpcbs.com/ which 
describes a set of aftermarket K2 option bypass headers.  By using them now 
after you have completed phase III alignment, you can make all of the 
necessary mods for all of the options all at once.

Other than removing the front panel if necessary to change FP-P1 (the 
mic configuration header) you shouldn't have to disassemble your K2 again.  
You certainly won't need to do any K2 PCB soldering more than once.

BTW, if you install RF-R29, RF-D19, RF-20, and change RF-C71, be sure to

also change the setting of the Extended VFO Range (D19) secondary menu 
from N to Y.

[Elecraft] Build Order: KPA100 KAT100-1 ?

[Craig Miller]

I presently have a K2 with KAT2 internal tuner. I do not have a KIO2
installed. I've just purchased the 100 watt amp and external tuner. My
question is which order I should build and test these two units: KAT100
first but no way to communicate with it to test it, or KPA100 first with no
way to use it except for a dummy load? If I build the tuner first is there a
way to tap in to the K2 enough to get the required communication signals
to check the tuner out?
 Any suggestions from the group?
Thanks,

[Craig Rairdin]

The KAT100 is a quick build and needs the I/O with the KPA100 for testing.
Do the KPA100 first. Once that's done and tested the KAT100 will go quickly.

installed. I've just purchased the 100 watt amp and external tuner. My
question is which order I should build and test these two units: KAT100
first but no way to communicate with it to test it, or KPA100 first with no
way to use it except for a dummy load? If I build the tuner first is there a
way to tap in to the K2 enough to get the required communication signals
to check the tuner out?
 Any suggestions from the group?
Thanks,
Craig K3OOL

Craig,

Build the KPA100 first (you can use it immediately with a dummy load or a
resonant antenna or any pre-tuned antenna).

If you build the KAT100 first, you will not be able to test it nor align the
wattmeter until you complete the KPA100 anyway, so it will just sit there
waiting.  It should only take a few evenings to build the KAT100.

[Elecraft] Build 100W amp tuner 1st - issues?

[nz7c]

Thinking of building 100W amp with tuner box before I start on a K2 - only 
because I have not built that particular box before and it would be the most 
interesting part of the project. If I do that, will not having a K2 in hand 
cause me a problem during the build - i.e. is there any part of the build that 
requires a K2 to be present for testing etc? Thanks in advance.

OK - I got it (from about half a dozen very nice folks!). Been awhile and I 
forgot completely that you cannot even buy the amp buy itself unless you have a 
K2 already - plus it does require interactive testing. Thanks everyone.

Hi Tim!
Yes. The KPA100 and most of the other accessories to the K2 communicate with 
K2 on auxbus.

The KPA100 need that line and some other lines as well to be tested.
There is also a test of the KPA100 that has to be done about midway in 
assembly that need the K2.
I suggest you download the manuals from elecraft webpage to se what your up 
against.

I just builded the KPA100 and wow!! have I had fun since.
Some minor problems , but soon to be taken care of.
