Re: [Elecraft] Elecraft Digest, Vol 124, Issue 15 KX3 CW Drift

[Bob]

Not that I had a "need" but I did instal the K3EXREF with a Trimble Thunderbolt 
GPSDO. So I have the 10MHZ reference available.


I also have no present "need" for the XV144 & XV432 to be locked to that 
external reference. However were a kit available to do it I would purchase the 
kit/accessory to do so.


i would like to see it as a product.

Focus Group Thoughts for Elecraft  Re: KX3 and K3 drift on VHF Digital 
Applications


What about adding an external phase lock option that would also allow
the 10 MHz reference phase lock and GPS sync?  Many of the digital mode aps are
needing this kind of stability and the KX3 with an internal 2 meter board or 
external XV transverter family choice.  The XV series transverter LOs could 
have a kit for phase lock too.


There are so many interested in WSPR and you have one of the gurus up north of 
Elecraft who's already done a design.  This also would bring the Elecraft 
product up to what's new and state-of-the-art for both the K3 and KX3 in 
digital communications

Re: [Elecraft] [K3] Fan Replacement

[Dr John Farmer]

Yes Jim, the published specs of the Noctua and Utec fans have been presented in 
this thread. The Noctua manufacturer's warranty is 6 years. It seems they have 
confidence in the fan's durability.

Hello Group,

I just want to share my experience in case it's of interest to others. 

I have excellent hearing and I have K3 #5102 and while it's a rig with
outstanding capabilities, the fan noise has always bothered me. My K3 has
the Utec fans and even on low speed, there's something about the quality of
the fan noise that's bothersome, quite apart from the volume, which I find
distracting even through over-ear headphones. 

Early on, I wondered if I had faulty fans from a bad batch. I replaced them
with a new pair from Elecraft, but they were as noisy as the originals. 

Well, today the problem is fixed. Inspired by Harry's posts on the topic, I
swapped over the Utecs for a pair of Noctua NF-A6x25s. It took 20 minutes. 
The difference took me by surprise.  They are very, very quiet even in a
silent room and I can't hear them through the headphones at all. The quality
of the sound is softer somehow - just like moving air and without mechanical
overtones! I worked CW for an hour tonight to get the rig warm and these
fans have transformed the experience.  I'm very pleased. Thanks Harry.

John

[Elecraft] Software modifications

[Jim Lowman]

I'm a big fan of open-source software but, as a software 
developer/supervisor with more than 30 years experience, I think it's 
worthwhile to know the big picture before messing with software that 
another developer wrote.

Sometimes it's not obvious why a segment of code exists.

And yes, I've rewritten others' software before, because it was easier 
to do that than to try to maintain it.

Re: [Elecraft] KDSP2 option's DSP firmware is open source

[Matt VK2RQ]

Even if you find the development kit, the memory chips in the latest K2DSP 
boards are not in sockets, but are soldered directly to the board. So, it would 
be difficult to upgrade the firmware on the K2DSP. Also, the firmware for the 
user interface is not open source, which limits the scope of adding features.

These days, if you want to experiment with DSP algorithms, it is probably more 
convenient to do prototyping on a general-purpose PC with sound card.

Re: [Elecraft] Fw: KX3 2 mtr ATU problem

[ejkkjh]

For follow-up - Problem ok now.
I moved the internal antenna cable and KX3 is working fine now.
This time I was very careful when putting the case back on.  I think the 
case moved the antenna cable out of position as shown on page 27, figure 21 
of 2 mtr module instructions.  Once antenna cable was not touching or over 
the toroidal inductor no problems with SWR.

Thanks Jeff for the tip and all others who responded.  73

I saw your post but I thought someone better qualified would respond.

I had a similar problem.

I went back into the unit to find the antenna cable had shifted and was
right over the top of one of the atu toroids.

see fig 23 in the assy manual.

i set it back to pointing direct to the card edge, closed it up re-tested
and was back in business.

Re: [Elecraft] K3 false SWR indication with SSB

[Mark, KE6BB via Elecraft]

Mark, 

This was addressed several months ago concerning the KX3.  When the software 
gets ready to display SWR,  it reads forward power, and a fraction of a second 
later, reverse power.  Since voice peaks go up and down, the displayed SWA will 
not be accurate unless you use a steady signal.

Subject: [Elecraft] K3 false SWR indication with SSB 

My k3 flashes a higher swr indication with ssb voice peaks than with a steady 
carrier.

If using an antenna with 1:1 SWR the bar graph flashes the first segment.  If 
swr is 1.5:1
all the segments illuminate on voice peaks, as if swr was greater than 3:1.  To 
reduce the 
uncertainty introduced by my antennas,  I connected a 50 ohm load after an 
external tuner 
so I could create the 1.5:1 SWR, and got the same results.

I assume this is a benign problem and likely caused by the non simultaneous 
sampling
of FWD and REV power by the CPU.  

However, if no one else sees this I'll do some more checking.

[Elecraft] Noctua fan for the KPA500

[Dr John H Farmer]

Good question! I had a look, but couldn't find a Noctua fan with the same specs 
as the stock Sunon which came with my KPA500. I did find that the fan noise on 
the KPA500 was reduced by mounting it on a silicone gasket and I'm happy with 
the improvement it made, so will leave it at that. Besides, there's much 
greater airflow through the KPA500 and I never expected it to be quiet, I just 
wanted to reduce the mechanical element to the noise. The gasket approach 
didn't help at all with the K3 fan noise, FWIW. 

If anyone explores the KPA500 fan situation further, I'd love to hear. 

Cheers, John

[Elecraft] Open Source

[Jim Finan]

There is a big difference between Open Source Software and Firmware. 

Elecraft provides programming info for those who want to write programs for 
their products (Software). If someone wants to write programs for Elecraft 
equipment and make it Open Source, it is permitted. 

On the other hand, I don't know of many manufacturers that provide Open Source 
FIRMWARE. While some manufacturers provide Firmware upgrades (like Elecraft), 
I'm not aware of any that publish source code for their firmware. 

Bigger computer vendors do provide firmware updates to their hardware but I've 
never seen one provide Source Code (Open Source). I come from a Unix background 
and much Open Source Software is available (and for Linux variants).  But not 
at the hardware level. 

No major corporation would implement software that they can't support and there 
are too many variables to use Open Source for every application. Not to mention 
security problems!

Jim

Re: [Elecraft] Changing the subject line

[Fred Townsend]

Fred, correcting the subject line might, I say might, affect a few thread 
followers. However the other readers will bless your intelligence in changing 
as we can delete without opening the file. While we at it why can't the poster 
put the proper subject line in the first place? Sometimes I think this is Mrs. 
Mayfield's kindergarten class where the followers get in line just because 
there is a line forming.

Re: [Elecraft] K3 false SWR indication with SSB

[Guy Olinger K2AV]

Peak SSB power can exceed the 100 watts if all the calibrations are
not current. You should very carefully make sure that the actual peak
power and the steady CW power are the same. Make sure that all the
manual's calibrations have been run.  In order to run right, the
firmware needs to know a small pile of things about your particular K3
to make performance standard. "Recently" does not give me warm fuzzies
about being adjusted to spec.

I have found that sometimes doing a firmware update will unglue some
of the stored data in the K3, both calibration and others, despite
Elecraft's protestations that shouldn't happen. Doesn't hurt to rerun
the ENTIRE set of calibration exercises every couple of years.  Not
with every firmware update for sure, but whenever an update is
followed by some previously unnoticed quirkiness I'll run them. That
way I'm on the clean side of things if I report a quirk to be related
to an update.  If the quirk was cleaned up by a calibration, one can
be assured that Big E will never be able to duplicate it and figure
out what was going on if I reported it without recalibration. I really
don't want to waste any of their time. They're more interesting when
they're working on their projects.

Re: [Elecraft] Elecraft Digest, Vol 124, Issue 11

[Fred Jensen]

Leaving the military in 1972, I supported my family in control system, 
communications, and software engineering, mainly for the military.  In 
due time I started leading more than one project at a time.  Since the 
open-source discussion came up on the list, I've combed my memory of all 
those projects past.  So far, I cannot come up with a single programmer 
[later "software engineer"] who, at least once, did *not* come to me and 
say, "The code's a mess, best thing to do is rewrite all of it."


I'll let everyone know if I remember one. :-))

Re: [Elecraft] Elecraft Digest, Vol 124, Issue 11

[David Gilbert]

I can just imagine the resource drain it would inflict upon Elecraft to 
investigate all the possible unexpected and unwanted side effects that 
might be buried in open source modifications to their products that 
could easily affect the broader reputation of their products in the 
marketplace, especially given the memory space and performance 
constraints of an embedded processor.  Not to mention, of course, the 
possibility of somebody burying a small chunk of malicious code.


I don't think your proposal represents low risk at all, particularly to 
Elecraft, but also to that portion of the user base who even stumble 
over officially released firmware upgrades and would now have to sort 
out multiple options competing for the same limited number of bytes of 
code, and in ways that may not be compatible. Elecraft's brand image 
hangs on EVERYTHING associated with their products ... not just the 
things they create themselves.  If somebody contributes a modification 
that adds a feature but harms something else, the rig bears the brunt of 
the loss in reputation.


I think possibly you may be the one that doesn't understand what this 
actually entails.


Dave   AB7E

p.s.  I missed your callsign, Andrew.  Care to give it?

[Elecraft] K3 false SWR indication with SSB

[Mark N2QT via Elecraft]

My k3 flashes a higher swr indication with ssb voice peaks than with a steady 
carrier.

If using an antenna with 1:1 SWR the bar graph flashes the first segment.  If 
swr is 1.5:1
all the segments illuminate on voice peaks, as if swr was greater than 3:1.  To 
reduce the 
uncertainty introduced by my antennas,  I connected a 50 ohm load after an 
external tuner 
so I could create the 1.5:1 SWR, and got the same results.

I assume this is a benign problem and likely caused by the non simultaneous 
sampling
of FWD and REV power by the CPU.  

However, if no one else sees this I'll do some more checking.

Re: [Elecraft] Elecraft Digest, Vol 124, Issue 11

[Don Wilhelm]

I have used several open-source programs on my PC.  I am a user, not a 
programmer, so I have a different perspective.
The "support" is through forums, and if you are not sufficiently skilled 
in "geek speak", there is danger that you will be flamed for asking a 
question, or you may receive an answer that is so thoroughly steeped in 
"geek speak" that it is useless for you.  Been there done that.
Besides you have to constantly monitor the forum to see if anyone has 
provided an answer to your question.


If a user has a problem with an Elecraft product and contacts Elecraft 
support, you can expect to discuss your situation with someone who is 
both responsive and knowledgeable and will work with you to resolve the 
issue or present it to engineering.  I highly suspect that would not be 
the case if the firmware were open-source.


Open-source is 'nice' for programmers who want to implement their pet 
additions, but for the majority of users, open-source is not the way to 
go IMHO.


73,
Don W3FPR


And yet open-source software has been shown to be very successful.  Why do you
think many corporate/government organizations are turning to it?



With enough eye balls looking at the code all bugs are shallow. I think
Elecraft could benefit from an extra 100 pair of eyes looking at the
problems at no cost contributing an average of 100 hours a week at it.

We take input, review it, and implement features and fixes we think are best 
for customers overall, while not introducing unwanted side-effects. We manage 
this process very carefully. 

Open-source projects work a lot better if one has essentially unlimited code 
space, as with PC applications. This is not the case with the embedded 
processors used in compact, power-efficient transceivers.

Re: [Elecraft] [K3] Fan Replacement

[Harry Yingst via Elecraft]

Thank you

That is the same I found

I hear the air move but not the fans

For me it really improved my listening pleasure





 From: Dr John H Farmer 
To: "elecraft@mailman.qth.net"  
Sent: Tuesday, August 19, 2014 7:02 AM
Subject: Re: [Elecraft] [K3] Fan Replacement
 

Hello Group,

I just want to share my experience in case it's of interest to others. 

I have excellent hearing and I have K3 #5102 and while it's a rig with 
outstanding capabilities, the fan noise has always bothered me. My K3 has the 
Utec fans and even on low speed, there's something about the quality of the fan 
noise that's bothersome, quite apart from the volume, which I find distracting 
even through over-ear headphones. 

Early on, I wondered if I had faulty fans from a bad batch. I replaced them 
with a new pair from Elecraft, but they were as noisy as the originals. 

Well, today the problem is fixed. Inspired by Harry's posts on the topic, I 
swapped over the Utecs for a pair of Noctua NF-A6x25s. It took 20 minutes.  The 
difference took me by surprise.  They are very, very quiet even in a silent 
room and I can't hear them through the headphones at all. The quality of the 
sound is softer somehow - just like moving air and without mechanical 
overtones! I worked CW for an hour tonight to get the rig warm and these fans 
have transformed the experience.  I'm very pleased. Thanks Harry. 

73,
John

Once upon a time, this was the argument behind all open source projects 
-- everyone is looking at the code, therefore every security hole will 
be seen as part of this massively parallel but highly informal code review.


If you want to see the truth, look at all of the websites out there that 
have been hacked because they're running some kind of open source 
framework.  Those sites usually used someone's open source upload 
component, but no one did a code-review for security issues before 
adopting the component(s) in question.


That's because people do not read code for pleasure, nor do they find 
great joy in smashing bugs.  They just use what they need, and do enough 
to get what they want.


Closed-source isn't the solution, but neither is open-source.

I too am happy with the way Elecraft currently operates.  Their products
are top notch, and their service is second to none in the industry.

Eric's good presentation at HamJam  2011 on
"Starting a Radio Company" shed light on some of the management decisions
they have made and helped us walk in Eric and Wayne's shoes re their

And yet open-source software has been shown to be very successful.  Why do you

[Elecraft] Need help with FTDI USB connection for W2 interface program in Linux

[NZ0T]

I am part of the team that will be displaying Elecraft products at the
Joplin, MO hamfest this coming weekend.   Taking my K3 and W2 to show and I
would like to be able to show the W2 interface program on my Acer netbook as
that program really enhances the W2.  The problem is that I recently changed
from Win7 to the Linux distro Zorin OS9 (based on Ubuntu) on the  netbook
and the interface software is only available for Windows and Mac.  I have
been able to get the Windows version of the program running using Wine but
have had no luck getting the FTDI USB cable to connect.  I am new to Linux
and really struggling with this.  Can anyone please give me a simple
(hopefully) step by step procedure on how to get the cable recognized and
working under Wine?

Thanks in advance!

73 Bill NZ0T

Re: [Elecraft] Elecraft Digest, Vol 124, Issue 10

[Ray Sills]

HI Andrew:

Well, we all can have our opinions about "list priority"... but in the  
end, it's up to Elecraft (Wayne and Eric), with feedback from  
customers and employees.


With regard to Elecraft "open-sourcing" their firmware don't count  
on it.  Especially if you like to have the current level of support.   
Let's see how Ten Tec fares with their open source rig.


As far as I can see, Elecraft is quite responsive to feature requests  
and bug fixes.  People often point to a -lack- of response from other  
manufacturers... including fixing -known- issues.  They just continue  
to make the same broken products.


In the end, things have been working quite well for Elecraft from a  
business perspective.  I doubt there would be any desire to change  
anything that "isn't broken" from their perspective, and from the  
perspective of most customers.

Hi all,

Our firmware task lists are sorted by priority. Determination of
Priority is democratic to some degree (Squeaky Wheel and other  
industry

standard methodologies). But in practice it involves
crystal-ball-gazing, head-counting, arm-wrestling-over-a-beer, and a
healthy dose of what-we-have-time-for.

It is not practical for us to publish the lists.



That is nonsense. There are plenty of tools to easily track issues and
feature requests in a way that is no burden on your time. The best  
thing
you could do is open source your firmware on GitHub and let other  
people

start working on issues.




They change daily and
contain a lot of firmware-speak. We'd rather spend time actually  
making

changes than on sanitizing lists for public consumption.



That is a job all in itself. It is called Product Management. If you  
don't
have anyone that does that full time now you should hire someone to  
do it.
If engineers are doing that now they should most definitely not be  
doing it.

No actually your premise is completely wrong. It will change that.  
Products
live and die by the feedback customers give to the company. With no  
public
issue tracking service offered by Elecraft of course it is going to  
look

like a black box when in reality the lack of transparency for change
requests is hurting the product.

People are making their own 3rd party products for Elecraft (for the  
KX3

for example) because "crystal-ball-gazing, head-counting,
arm-wrestling-over-a-beer, and a healthy dose of what-we-have-time- 
for"

doesn't scale.

Re: [Elecraft] [KX3] Case for KX3

[Dennis Griffin]

Thanks Gerry, but I'm not the one looking for a case. I was offering 
suggestions for an OM named Jim, who I believe is looking for a transportable 
protective case for his KX3 & accessories. Aren't Rose's "cases" essentially 
just a dust cover, bearing an embroidered call sign or such if desired, for 
stationary units in a shack?

Re: [Elecraft] [K3] Fan Replacement

[Dr John H Farmer]

Hello Group,

I just want to share my experience in case it's of interest to others. 

I have excellent hearing and I have K3 #5102 and while it's a rig with 
outstanding capabilities, the fan noise has always bothered me. My K3 has the 
Utec fans and even on low speed, there's something about the quality of the fan 
noise that's bothersome, quite apart from the volume, which I find distracting 
even through over-ear headphones. 

Early on, I wondered if I had faulty fans from a bad batch. I replaced them 
with a new pair from Elecraft, but they were as noisy as the originals. 

Well, today the problem is fixed. Inspired by Harry's posts on the topic, I 
swapped over the Utecs for a pair of Noctua NF-A6x25s. It took 20 minutes.  The 
difference took me by surprise.  They are very, very quiet even in a silent 
room and I can't hear them through the headphones at all. The quality of the 
sound is softer somehow - just like moving air and without mechanical 
overtones! I worked CW for an hour tonight to get the rig warm and these fans 
have transformed the experience.  I'm very pleased. Thanks Harry. 

73,
John

With enough eye balls looking at the code all bugs are shallow. I think
Elecraft could benefit from an extra 100 pair of eyes looking at the
problems at no cost contributing an average of 100 hours a week at it.
Could you imagine what kind of quagmire that could result in? A better
product no less!

You don't seem to understand what this entails. Elecraft would still
control software updates including open source contributions. The Internet
is built on open source protocols and software and ham radio manufacturers
would be wise to follow suit. This is a low risk, high gain move with
nearly zero switching cost.

Re: [Elecraft] [KX3] Case for KX3

[David Anderson]

For those in the UK, I use this bag which takes the KX3 with the extra heatsink 
and side handles fitted etc, plenty of room for all the other gubbins you need, 
extra batteries, key, mic, wire antenna, head set. I think I bought mine it was 
in a sale and was even less expensive too.
It has a waterproof cover too, though I have never used it.

http://www.7dayshop.com/products/7dayshop-canvas-photo-messenger-shoulder-bag-DS-014

Being into photography as well as amateur radio, I have a collection of very 
expensive camera bags as I try to find the ideal one for various cameras and 
lenses, but I must say I think the 7dayshop one is as well thought out and 
protective as those much more expensive bags.

That is nonsense. There are plenty of tools to easily track issues and
feature requests in a way that is no burden on your time. The best thing
you could do is open source your firmware on GitHub and let other people
start working on issues.

That is a job all in itself. It is called Product Management. If you don't
have anyone that does that full time now you should hire someone to do it.
If engineers are doing that now they should most definitely not be doing it.

No actually your premise is completely wrong. It will change that. Products
live and die by the feedback customers give to the company. With no public
issue tracking service offered by Elecraft of course it is going to look
like a black box when in reality the lack of transparency for change
requests is hurting the product.

People are making their own 3rd party products for Elecraft (for the KX3
for example) because "crystal-ball-gazing, head-counting,
arm-wrestling-over-a-beer, and a healthy dose of what-we-have-time-for"
doesn't scale.
