Re: [Elecraft] KX3/PX3 Linux Utilities for Raspberry Pi?

[Erlend Grimseid]

Add me to the list also.
Both for the pi and x86 Linux.

Or just open source it and it will sort it selves out.

Only thing is. If it's compiled from source by some 3rd party Elecraft can
most certainly not be held responsible for the software bricking your radio
or what ever Elecraft product you are trying to update.

The best thing would be for Elecraft to compile and quality control it
their selves.

Re: [Elecraft] low IF out on K3

[Enrico Lorenzoni IU3AZC]

hello everyone. My K3 is # 80XX so it should be fine.
With my multimeter I checked R8 and it's reading 270ohms (mounted on the 
board).
From the schematic I guess there should be no DC flowing and that I 
should read 13.3k, so I think R8 is broken or the problem is in Q10 fet, 
being resistive on the gate.
anyone has experience in this, before I start desoldering components and 
measure them?


thanks

Enrico

Older K3 transceivers (built before September 2009) do have lower output
than later units. Elecraft published a modification that involves replacing
a single resistor to bring up the level.

They have a kit that includes an SMD and a leaded resistor (you can use
either, only one is installed). Order the KIO3BUFFKT. You can see what is
involved by reviewing the instructions available for download here:

http://www.elecraft.com/K3/mods/IF_Output_Buffer_Gain_Mod_Rev_A.pdf

If you have a 13K ohm, 1/8 watt leaded resistor or if you'd rather work with
an SMD, a 13K 0805 size resistor, you won't need the kit.

Subject: [Elecraft] low IF out on K3

hello everyone,
I just compared my k3 with a friend's one and my IF out is much lower than
his k3.
I suspected it when listening on a softrock, but now I can see a difference
like 10 or 20db off.

So I inspected my k3 and the IF out connector is fine. Multimeter says 0
ohms between bnc contacts and P86 pins on motherboard.
What can I check next?
Anyone did fix this same issue?

thanks

[Elecraft] [KX3] The Long Way 'Round to a Wooden Stand

[Joel Black]

It is Spring in Alabama. We are now in our fourth week of nice weather (other 
than our typical t-storms) but it won’t last. This is the longest I can 
remember having mild weather before the heat and humidity kick in. In a couple 
of weeks, it will be time to start planting the garden. It is so nice out, I am 
always trying to find things to do outside. My neck has already been turned red 
several days this year - my understanding is that this is *not* where the term 
redneck originates but from the Scots who used red bandanas to shield them from 
the sun. Regardless, I am part Scot so I consider this a term of endearment 
regardless of what others may think. 

A few years back, I bought several pieces of cedar from a mill whose owner I 
know. Those pieces have come in handy to build my raised-bed gardens and 
provide support for my various scuppernong, muscadine, and grape vines. 
However, I have several scrap pieces left over. As some of you may know, cedar 
is rot- and bug-resistant. I took one of the 4x4 cedar post scraps and cut a 
couple of notches out of it and made a crude stand for my KX3. Well, I’m always 
tinkering around and got to thinking about some of the cedar 2x4 scraps I have.

I have in my mind exactly what I want to do by cutting the 2x4 scraps into 1/2” 
thick strips and joining them into a plank with my biscuit joiner. I would like 
to build a stand that will hold both the KX3 and the PX3 (don’t have one yet 
but I may buy one) and I need to confirm the total width is 13 1/2”. I think I 
added up 13.3” but my measuring stick does 32nds not 10ths. :) If it turns out 
okay, I’ll provide pictures.

Is this what happens when you approach 50? You start waning anecdotally?

Thanks for the bandwidth.

73,
Joel - W4JBB

Re: [Elecraft] K3 UOS?

The question and the asker have been beaten to a pulp with these answers 
(some rather insulting). All that was asked could have been answered 
with a simple yes or a no.


This is exactly why many, and myself, are reluctant to ask questions here.

Just measured mine and total end to end is 13 5/8"  You need to take into
account the right angle connectors on the left side of the KX3.  This is
with the PX3 to the left of the KX3.

Hi,I am  rather new to this forum.  I have recently bought a K3S and am 
thinking of buying both the P3 and the P3VGA.  Presently, I am using Fldigi on 
my computer and mostly  operatewith PSK and sometimes some CW. If I buy these 
am I being redundant or does it make sense to buy them?  I am hoping that some 
of the members of this forum are using Fldigi and P3, and can answer the query.

Re: [Elecraft] [KX3] The Long Way 'Round to a Wooden Stand

Two days of relatively hot weather has made the spicy cedar smell 
dominate the spring breeze.  Oregon is not known for its sunshine this 
time of year; it feels odd, but the biting flies love it.  No way for me 
to get a red neck here since I need a towel over my head to cut down on 
their feeding frenzy.  {It rose to 77 degrees yesterday where normally 
it should not exceed 50.}  Two of my redcedar trees are used for antenna 
supports.  The rest protect me from straight line winds.

Re: [Elecraft] (no subject) [FLDIGI vs P3]

[Bob Novas]

Dick - The P3 and Fldigi are really looking at very different signals and have 
very different uses although there is some overlap, and that's what maybe gets 
confusing. The P3 is a "fish finder" for a big hunk of a band - the P3 looks at 
the K3's IF and can represent as much as 200kHz of it (but, it can also 
represent a small portion of it, which is where it starts looking like fldigi). 
 Nevertheless, the P3 allows you to do things you cannot do with fldigi. You 
can use the P3 to tune the radio to an SSB signal visually - and by that I mean 
not only can you see the signal, but also you can set the radio's receive 
frequency to be appropriate to receive the signal without spinning the dial.  
You can also use the P3 to look at a small span, and to decode RTTY -this is 
where it is like fldigi.  But, in my opinion, fldigi is a lot better at doing 
this than the P3, and on the other hand, fldigi cannot do what the P3 can with 
respect to tuning or visualizing band conditions.  Bob  W

Re: [Elecraft] KX3/PX3 Linux Utilities for Raspberry

[Phil Wheeler]

Regarding the RPi, I like experimenting with it 
but as a shack computer the idea of a separate 
computer unit plus monitor plus keyboard seems a 
bit of a kluge.


Just now my shack computer is an 11" 2010 MacBook 
Air with 250GB SSD. It runs both Windows 10 and OS 
X 10.11.4, so I can use the many ham apps (such as 
EZNEC) unique to Windows and not requiring too 
much computing power. A real plus is that it can 
sit in front of my K3 or KX3 and I can still see 
the rig's front panel over the top of the 
computer's monitor -- and the monitor is plenty 
large enough for the digital modes, and the 
keyboard is full size.


My most compact RPi set up now is an RP2 with a 
small keyboard with trackpad and a 7" HDMI 
monitor. Due to the separate boxes that takes up 
more space than the 11" MacBook Air, while having 
a smaller-than-normal keyboard and a screen which 
is a challenge to use.


So I just don't get all the enthusiasm for using 
an RPi (or BBB) as the shack computer to support 
the Elecraft utilities, etc.  No problem with 
Linux (which I can run on the MBAir, and do run on 
my RPi2), just with the physical arrangement.

[Elecraft] Elecraft Utilities

[Ken G Kopp]

Wayne and Eric:

PLEASE don't cave in to the requests of those on the reflectors who are
asking
you to disclose the "genetic makeup" of their radios by publishing the
software
that would enable anyone to modify how a given radio operates.

I see this as no different than a breeder of a thoroughbred breed of dog
opening
the pen and letting all comers mate with the females.  You would end up
with a
"contaminated" breed.

I envision an increased workload at Elecraft in dealing with the customers
who
manage to "mess up" their radio's "brains" and want help in restoring them
to
the original state.  Nothing but non-profit overhead.

I would be wary ... read "never" ... of buying a used Elecraft product for
fear
that it's genetic makeup had been altered and really wasn't an Elecraft
anymore.

Perhaps I'm not understanding something ...

[Elecraft] KX3/PX3 Linux Utilities for Raspberry Pi?

[Alan Geller via Elecraft]

Please put me on the list of interested KX3 owners. The idea of Elecraft 
maintaining and qualifying this software is great,
but there is a lot of it and it will incur costs. However…it could be a 
productive and low cost path for Elecraft to evaluate
it’s next product line which could be a more highly integrated computer/RF 
system. Even though I have been in this business
most of my life, I am still amazed at the capability one can have for 
$35….almost enough for lunch for 2 in Silicon Valley.

Re: [Elecraft] New K3S was No Subject

[Dave Cole]

Hi,
The P3 doest not duplicate any function FLDigi does, save a few modes
for Digital use.  I prefer a full sized computer screen for digital, so
using the P3 for digital never happens here...  

The real advantage of the P3/SVGA is the band-scope, or Panadaptor.  It
shows you most if not all of a band at once, and you can zoom in and
out looking for open spots to call your DX, or spot a pileup from
across the band, etc...  In a pileup, I can see the holes, and the
stations that the DX is talking to, so I know where he is listening
at...  

For me, the SVGA is a godsend, it allows me to send macros to the K3,
and to put the screen on a different monitor...  If you look here:
http://nk7z.net/station/
you will see photo of my Operating position.  Click that photo, and it
will expand, then look in the upper right hand portion of the area
where the monitor is.  You will see a second, smaller monitor, showing
the P3 displayed in a different view, and larger than the native P3
display...  That monitor is switchable and I can switch in a cluster
view, or a prop map view into it for day to day use...  The SVGA allows
me to add the P3 as well.  

I also fire off macros at the K3 using the keyboard input on the back
of the P3.  See:
http://nk7z.net/adding-an-external-keypad-to-the-k3/
for a full description on how to connect a remote keypad to your K3,
using the Keyboard function the SVGA provides...

I had occasion to use a friends K3, and he did not have the P3...  It
felt like I had been hobbled to not have it, I had lost the "feel" of
the band one gets when one can see most of it at one time...  

He commented that that seemed a bit over the top, then tried my setup
in a pileup--  he now has a P3 as well...  

So in short is it worth it?  For me-- absolutely!

Re: [Elecraft] K3 radio no receive no transmit

[Russ Tobolic]

Do you have the new KSYN3A?  I just experienced a similar problem but tapping 
on the case didn't solve anything. Elecraft support determined I have a bad 
synthesizer. Russ, N3CO

 Subject: [Elecraft] K3 radio no receive no transmit
   
My K3 is acting up a bit. No Receive No Transmit. I operate this radio 
remotely so all I can tell you is that it appears to be all working as per the 
HRD screen I am looking at. The radio appears to switch to transmit and I 
hear the monitor CW being sent but no output on the wattmeter.  The only 
noise coming from the radio is inter radio noise it the volume is turned to 
max. A slight TAP on the top of the case and the radio goes back into 
perfect normal operation. I am guessing that some plug someplace inside 
the radio isn't making proper contact. 

Does anyone have any idea which plug and its location?

Thanks

Re: [Elecraft] Elecraft Utilities

[Jessie Oberreuter]

W5QD et. al.,

 Ken is referring to the following message, which essentially requests 
a simple command-line firmware loader program.  Note that this is NOT a 
request for DNA level access to the radio's internals.
 The communication protocols for most of the Elecraft radio functions 
are described in the public documentation, enabling people to write their 
own code for most functions.  The firmware loading protocols, however, are 
not. The only way to update the firmware (not generate our own!) is to 
download and run platform specific GUI applications from Elecraft.  For 
most users running Windows or MacOS, this is fine: virtually all of these 
users expect GUI software, have their computers directly connected to 
their radios, and aren't aren't running on unusual computer hardware.
 For those of us running Linux (or even more obscure operating 
systems), a GUI application that only works on x86 machines that are 
directly connected to the radio is awkward.  My laptop and all of my shack 
machines are ARM based, so when I need to upgrade my K3, I need to extract 
it from all of its cables and haul it over to my x86 work machine.  My 
work machine is running 64bit linux, while the Elecraft tool is 32bit, so 
I also need to install 32bit versions of several libraries to run it. 
Similarly, all of my radio gear at home is actually hooked to a 
serial-to-ethernet device, which is great for all of the software I use, 
but not fine for K3Util, which expects to talk specifically to a directly 
connected hardware serial port.
 There are several approaches to solving this problem.  The first is 
to ask Elecraft to provide more versions of their software: can I get an 
x86_64 build?  ARM7 please!  Actually, I use my Android for everything ... 
can I get an Android app?  Fortunately, we recognize that Elecraft is a 
/radio/ company, /not/ a consumer software company, and we don't want to 
ask them to spend time supporting dozens of firmware loaders.  Ideally, we 
would like to see or, with access to the protocol documentation, develop 
an open-source library for updating the firmware. Then we can build our 
own firmware loaders for whatever platforms we choose.
 Recognizing that this may be asking for proprietary and/or licensed 
information, Bruce has suggested a middle ground -- offer a simple "glue" 
interface (a command line firmware loading tool) that would be much 
simpler for Elecraft to build for lots of different platforms and would be 
more in line with the linux philosophy of starting with light weight 
command line tools, and adding far more difficult to develop and maintain 
GUIs on top as desired.


 Perhaps a simpler option would be to offer a library or command line 
tool in a portable format that still obscures the proprietary protocol 
implementation.  Java is a good candidate for this, as there are Java VMs 
for practically every platform out there.

Subject: [Elecraft] Feature request: Command line firmware updater

Hi folks,

As the subject suggests, I'd like to put in a feature request, for a 
simple, command line firmware updater tool, for all applicable Elecraft 
rigs. To update the firmware on my KX3 and PX3, I need to download and set 
up two separate programs, most of whose functionality I won't ever need.


Such a tool would be easy for Elecraft to write and maintain, and would be 
easy to make work on different platforms, which brings me to the next part 
of this feature request. I'd like to be able to run this tool both on my 
Intel Linux machines, and my Raspberry Pi, which is hooked up to my KX3 
and PX3 whenever my KX3 is home. Cross-compiling such a simple tool should 
also be pretty easy.


I'm sure there are other people who're in similar situations, and would 
appreciate something to address these use cases. Firmware updates are one 
of the few things where you can't roll-your-own.


Thanks.

Bruce

The utilities are not the same as the internal radio firmware.

To take your horse breeding analogy, it's like the type of feeder the

Re: [Elecraft] Elecraft Utilities

[lstavenhagen]

Yes, my question was partly rhetorical - I don't recall seeing any requests
for access to any of Elecraft's proprietary code, or the ability to modify
it. So I was also a bit mystified by Ken's post.

I think you make a good point but, like you said, Elecraft is primarily a
hardware company, not a software company. A layered approach to something
low-level like firmware that maintains the secrecy of what needs to be kept
secret but at the same time presents an interface to customers that does
everything needed isn't an easy or quick thing to design and implement. It's
a non-trivial thing to do both from a technical and confidentiality
standpoint. 

So I'm sympathetic, but it might not pass the cost/benefit threshold for
Elecraft to do that. It's probably cheaper right now to simply maintain and
distribute a limited set of binaries for this at the current time than to go
to a major development project like a firmware SDK and all the language
bindings that would be needed and so forth.

I doubt it'll be possible to "rewrite the DNA" of an Elecraft rig anytime
soon, if ever, so I wouldn't worry about that either.

Re: [Elecraft] Elecraft Utilities

[Tim Henrion]

People building their own firmware loaders is a really bad idea if one possible 
outcomes is brick’d radios. Consider the potential support costs of these types 
of things. Java is not the answer. It is too dependent on the quality/buginess 
of VMs on less mainstream platforms.

I’m a Mac guy and I can’t tell you how many pieces of embedded hardware I own 
whose updaters only run on Windows. There’s a real easy solution. Get a cheap 
Windows machine, run the software under VMware or Wine or whatever you need to 
get the job done. The LAST thing I’d want to see is Elecraft wasting valuable 
development time on stuff other than designing/building radios. Multiplatform 
software, unless its the primary business you’re in, is a sinkhole waiting to 
happen from a development and especially support perspective.

Re: [Elecraft] Elecraft Utilities

[Gary]

And the rub for me is, IF Elecraft did develop what is being asked for, what 
cost would they place on it, what ongoing costs are involved and who pays?
If this would add to their overhead, there will need to be a cost recovery 
mechanism and would this be passed on by way of a hardware price increase?
I don't want to see my future purchases increase in cost to cover "features" I 
am not likely to use in my lifetime.
Call me selfish if you like but I don't have a bottomless pit of money to spend 
on a hobby.

[Elecraft] FS receive antenna splitter for K3 with Sub RX

[Mike K2MK]

Hi,

If you have a separate receive only antenna for your K3 or K3S and if you
have a Sub RX you might want to split the antenna signal between the AUX RF
port and the RX ANT IN port. If you only have your antenna connected to the
AUX RF port you will not be able to use it for your Main RX. There are other
ways to accomplish this but this is simple and clean. There is a 3db
insertion loss with this device on each leg.

It is the DX Engineering RSC-2 splitter which you can view at:
http://www.dxengineering.com/parts/dxe-rsc-2

If you have technical questions please look at the manual on the DX
Engineering website.

It works great. It can also be used to combine two separate receive
antennas.

DX Engineering sells it at the lofty price of $71.95 plus shipping. I am
selling it for $40 and I will include priority mail to the the contiguous 48
states. I don't want to sell it internationally. 

Please contact me off list at:
k2mk at comcast dot net

I'm not checking the reflector daily so please don't post questions or
offers here.

73,
Mike K2MK

Presumably you can do similar tuning tricks in modes other than SSB?

I'm interested in this because I'm saving up for the PX3 to go with my KX3

Re: [Elecraft] Elecraft Utilities

[Don Wilhelm]

To ask Elecraft to provide Utilities for any and all small operating 
systems is unreasonable IMHO.  The mainstream OS of Windows, Mac and 
Linux *are* supported, but recently there have been a number of OS 
variants that have appeared on the horizon (and there are likely to be 
more to come) and that includes the Rasberry Pi, and several other 
'computers' that have recently appeared on the hobbyist market.


Just because the most recent device can do RS-232 (or USB) 
communications does not mean it should be individually supported by 
hardware manufacturers.  It would be more productive to encourage those 
writing software for those devices to request that they emulate Windows, 
or Mac, or Linux in all aspects so one could use the applications 
written for those mainstream OS versions to run without problems on 
whichever platform those "hobby" devices may be using.


If the Rasberry Pi OS becomes stable over time, and is in use for a 
significant percentage of the Elecraft community, then it may eventually 
be supported on its own,  but for the time being, as I understand the 
Raspberry Pi, its OS is a version of Linux, but not everything works 
like the main Linux platform -- so until you can convince the Raspberry 
Pi developers to create a version of its OS that is compatible in all 
respects to Linux, you will not have success.  The market penetration 
for Raspberry Pi is just not great enough at this time for manufacturers 
to create software that will run on it.  Much to the dismay of those who 
have Raspberry Pi running and controlling their ham stations.

Re: [Elecraft] Elecraft Utilities

[Eric Swartz - WA6HHQ, Elecraft]

Agreed.  Let's end the thread for now. (feel free to email with any questions.)

I apologize, but open sourcing the utility would create a number of problems and 
significant extra support expense that we can not afford. Improper use of that 
proprietary interface can certainly brick the radio, and in some cases actually 
damage the hardware. That's something that would not be a warranty repair..


We are not staffed to develop and support utilities for a wider range of 
hardware and operating systems right now. We're already support multiple 
versions of Windows, Mac OSX, and some versions of Linux. That's a lot more than 
most radio companies. Continually expanding beyond that also becomes 
exponentially expensive in a specialized market the size of this one.


That's likely the max we can do in the near term as we're primarily focused on 
designing new cool products for everyone. I'm not ruling out other OS utilities, 
but its likely nothing will appear near term as we have our hands full on other 
projects.


Feel free to email me directly with any questions.

W5QD et. al.,

 Ken is referring to the following message, which essentially requests a 
simple command-line firmware loader program.  Note that this is NOT a request 
for DNA level access to the radio's internals.
 The communication protocols for most of the Elecraft radio functions are 
described in the public documentation, enabling people to write their own code 
for most functions.  The firmware loading protocols, however, are not. The only 
way to update the firmware (not generate our own!) is to download and run 
platform specific GUI applications from Elecraft.  For most users running 
Windows or MacOS, this is fine: virtually all of these users expect GUI 
software, have their computers directly connected to their radios, and aren't 
aren't running on unusual computer hardware.
 For those of us running Linux (or even more obscure operating systems), a 
GUI application that only works on x86 machines that are directly connected to 
the radio is awkward.  My laptop and all of my shack machines are ARM based, so 
when I need to upgrade my K3, I need to extract it from all of its cables and 
haul it over to my x86 work machine.  My work machine is running 64bit linux, 
while the Elecraft tool is 32bit, so I also need to install 32bit versions of 
several libraries to run it. Similarly, all of my radio gear at home is 
actually hooked to a serial-to-ethernet device, which is great for all of the 
software I use, but not fine for K3Util, which expects to talk specifically to 
a directly connected hardware serial port.
 There are several approaches to solving this problem.  The first is to ask 
Elecraft to provide more versions of their software: can I get an x86_64 build? 
 ARM7 please!  Actually, I use my Android for everything ... can I get an 
Android app?  Fortunately, we recognize that Elecraft is a /radio/ company, 
/not/ a consumer software company, and we don't want to ask them to spend time 
supporting dozens of firmware loaders.  Ideally, we would like to see or, with 
access to the protocol documentation, develop an open-source library for 
updating the firmware. Then we can build our own firmware loaders for whatever 
platforms we choose.
 Recognizing that this may be asking for proprietary and/or licensed information, 
Bruce has suggested a middle ground -- offer a simple "glue" interface (a 
command line firmware loading tool) that would be much simpler for Elecraft to build for 
lots of different platforms and would be more in line with the linux philosophy of 
starting with light weight command line tools, and adding far more difficult to develop 
and maintain GUIs on top as desired.

 Perhaps a simpler option would be to offer a library or command line tool 
in a portable format that still obscures the proprietary protocol 
implementation.  Java is a good candidate for this, as there are Java VMs for 
practically every platfo

[Elecraft] K3 front panel switches

[Fred Jensen]

My K3, S/N 642, has been slowly developing "front panel dementia" [as am 
I as I accumulate birthdays].  A number of the switches are becoming 
intermittent, and often, the first push of one causes a totally 
unrelated action [e.g. tapping BAND UP turns on NR].  It doesn't happen 
with all of them and it seems like the ones I use the most are pretty 
stable.  I find that a really positive actuation, as in hard, often 
makes it work correctly.


My K3 is getting somewhat long in the tooth as the S/N would indicate, 
but I was under the impression that the front panel switches were rated 
at multi-millions of operations, and I'm sure I haven't come remotely 
close to exceeding that.  My truck is 13 years old and is developing 
similar symptoms [Tach says the engine is doing 6,000 RPM sitting in the 
driveway :-)]


Curious:

1.  Anybody else experience this?

2.  If so, what did you do?

3.  How do I tell if it's time to send it into the Big E?

Re: [Elecraft] (no subject) [FLDIGI vs P3]

[Don Wilhelm]

Brandon,

The PX3 (or P3) give a spectrum analysis of the portion of the band that 
is included in the Span (up to 200 kHz) as well as a waterfall display.
Signals within that band can be identified as SSB, CW, PSK, RTTY and 
many other modes on the spectrum display.  The spectrum display is a 
'real time' display of signals currently on the band.
The waterfall shows signals over time which shows signals that have been 
present in the past.  That is helpful for identifying weak signals.


With FlDigi (or other soundcard digital displays), you are looking at a 
portion of the band that is as great as the filter in use in the 
receiver (usually up to 2.7 to 3kHz wide - the bandwidth of the filters 
being used in the transceiver).  The modes that can be decoded depend on 
the software application (FlDigi has many).  There is no spectrum 
display, you have only the waterfall.  Click on the signal of interest 
in the waterfall and it will be decoded as long as you have selected the 
proper digital mode for that signal.


With the K3, when operating soundcard digital modes, you should be set 
to DATA A rather than SSB (if decoding RTTY, set to AFSK A). Data modes 
on the K3 (and KX3) automatically set the compression to zero and the TX 
EQ to flat even though you may have different settings for SSB.
If compression or TX IQ is used for digital modes, distortion will 
result.  Yes, you can adjust those settings in SSB mode, but why bother 
when the K3/KX3 will do that automatically for you by using DATA modes.

Re: [Elecraft] Elecraft Utilities

[Don Wilhelm]

Dave,

What is the "profit center"?
Elecraft provides the firmware at no cost, and the Utilities to load 
that firmware at no cost to the customer - that is an expense, not a profit.
Additional support is a loss to Elecraft because of the development 
dollars.  The Raspberry Pi (and its variants) element is small compared 
to supporting the mainstream OS Utility applications.

Re: [Elecraft] KX3 VFO B skipping

[Don Wilhelm]

Tim,

Sorry, but I do not have that information.  You can get the replacements 
from Elecraft parts, but as far as alternatives (detented encoders), I 
have no idea.


Since the controls are encoders rather than potentiometers, I think 
using something detented would not be the best thing.  The detent is 
mechanical and is not likely to line up with the firmware decoding of 
the encoder rotation.


Of course, I am thinking of a 'center detent', but if you are thinking 
of those awful encoders that have a detent at each movement of the knob, 
count me out, those are terrible to use IMHO.


You can get stock replacements for the encoders from Elecraft.

Re: [Elecraft] K3 front panel switches

[Ron D'Eau Claire]

I've not experienced that with my K3 which goes back to 2008 (S/N 00010),
but I would suspect corrosion on contacts. You might remove the front panel
assembly from the K3 and then plug it in again, and possibly do the same for
the DSP board. I've seen others suggest exercising the troubled switches
many times to good effect. 

One reason I've not experienced it on ol' number 10 is that every time there
a question about the assembly procedure or a kit change it comes apart to
check the changes. The contacts get exercised a lot. 

I don't recall if you built your K3 from a kit, Fred, but if not download
the KRX3 manual from the Elecraft web site. It has detailed instructions for
R/R the front panel assembly as part of the sub receiver installation.

After splitting logs for an hour this afternoon with trusty axe, I feel like
my personal "tach" is on the peg just sitting here (puff, puff, puff). I
might be experiencing some "corrosion" myself and in need of more exercise.

Re: [Elecraft] KX3/PX3 Linux Utilities for Raspberry

[Brendon Whateley]

Phil,

With all due respect, your use case is clearly different from those of us
who are so enthusiastic. I've not had a Windows PC since XP was a new
thing, and I have no interest in going back to Windows. Our house is all
MacBook Pro and various Linux machines, including a growing number of RPi.
So the fact that you are happy with running Windows on a Mac is unrelated
to the fact that I want to dedicate a RPi to the shack duties and have
another in my Go Box so that I can literally grab my KX3 and hit the road
without messing with computer stuff. That way the shack RPi can be
permanently attached to its monitor, keyboard, mouse, etc. And the Go Box
can be configured for a small bluetooth keyboard/mouse device I have.

The RPi has the needed power for this use, and at $35 I can have several
for different locations as needed -- something I am not prepared to do with
MacBooks.

What this thread is showing is that there is a growing number of people who
feel that a RPi is a perfect solution for this use case, and if not that,
then some other Linux machine. We are hoping that Elecraft will open source
the utilities so that folks such as myself can help make this a reality.

Commenting on a thread to say "this doesn't apply to me, so I don't see why
anybody else would care" is a little self centered and leads to an
unfortunate tone which is so common in HAM communities -- it discourages
new hams such as myself from getting involved, or asking questions.

[Elecraft] Cedar Stand for KX3 and PX3

[Dauer, Edward]

Joel -



Keep in mind the fact that the required width would include spacing for 
the various mini- plugs that connect the PX3, the KX3, the 12 VDC, the key 
(if you use one other than the built-in) and the headset.  Add to that the 
fact that the plugs need additional space between the units to be removed 
from the jacks, and maybe a bit more to get your fingers on them.  Don’t 
ask me at what cost I became aware of these details . . . or what happens 
after passing 70.

Eric closed this thread, but I must reply since 
you put words in quotation marks which I never 
wrote ("this doesn't apply to me, so I don't see

and misleading of you, and amazing that you would 
do so.


What I did say was "as a shack computer the idea 
of a separate computer unit plus monitor plus 
keyboard seems a bit of a kluge." and nothing you 
said relates to that statement.


I also said:

"So I just don't get all the enthusiasm for using an RPi (or BBB) as the
shack computer to support the Elecraft utilities, etc.  No problem with
Linux (which I can run on the MBAir, and do run on my RPi2), just with the

and part of your reply did address that.

But inventing quotations which I did not say: Truly Troubling.

[Elecraft] [K3] Setting RF gain & AGC correctly

[Al Lorona]

Again and again, I have asked (privately) those reporting 'bad K3 audio' to 
furnish me with settings, measurements, recordings -- anything-- but I haven't 
ever received anything with which I could diagnose the problem.

Bad. Noisy. Fatiguing. These adjectives have been used continually to describe 
K3 audio. I believe you, I just don't know exactly what you're hearing.

In the meantime, the analysis and recommendations that Ian, GM3SEK made here on 
23 March are excellent and what I would consider required reading for anyone 
plagued with 'bad audio'. I must second all that he said.

In conjunction with Ian's tips, if you're not in the habit of using Bob, 
K4TAX's technique [see below] to set your RF gain correctly, please consider 
doing so. I have come to believe that many hams may not want to turn down their 
RF Gain (or turn off their preamps, or turn on their attenuators) perhaps for 
fear of not hearing very weak signals? However, you can't hear anything below 
the atmospheric noise level... so once the receiver can hear the external noise 
floor, any further sensitivity or gain doesn't buy you anything and only 
increases the noisiness -- which is what many of the complainants complain 
about.

I think it was about six years ago that I conducted a double-blind survey here 
on the reflector in which I presented hi-fi recordings of four different 
receivers-- including an unmodified K3 with the old DSP board-- and asked folks 
to identify the K3. I hypothesized that the 'noisy' and 'fatiguing' audio that 
many reported would make it easy to pick out the K3 from the group. [The other 
receivers in the test were an Omni VI, a K2, and a Ten Tec 1340.]

The results were exactly the same as random chance guessing, and the loudest 
critics of the K3 at the time were conspicuous by not participating. I don't 
know why; this only served to increase my frustration. At the time (and up to 
this day) my K3 AGC parameters were almost exactly those recommended by GM3SEK.

Anyway, please try all of these great techniques that have been presented in 
the past few weeks because I really believe they can help. Thanks for letting 
me beat this one to a pulp. [Now, if you want, you can beat me to a pulp 
privately instead of overloading the reflector.]

Re: [Elecraft] [K3] Setting RF gain & AGC correctly

[Don Wilhelm]

The K3/K3S AGC settings have a lot to do with the apparent "noisy K3" 
syndrome.

IMHO, the K3 default AGC settings are not optimum.
Look at my website www,w3fpr.com for information on how to customize 
your K3/K3S/KX3 AGC settings to optimum for your ambient noise and 
operating preferences.  You will find a 'different receiver' when you 
adjust the AGC parameters.


Pay particular attention to the method of evaluating the results. You 
must do the evaluation on pauses in the SSB communications or 
word/sentence breaks in CW.  If you try to evaluate based on band noise 
alone, you will end up adjusting the parameters "backwards", and the 
result will be worse than when you started.

Re: [Elecraft] [k3] Isotropic Antenna

[Doug Person via Elecraft]

I wrote an article for 73 many years ago where I effectively remade the 
Isotron antenna with parts from Home Depot.  At the time, a 20 meter 
version could be built for about $15.  I tested my version extensively 
and for the most part a dipole made with two Hamsticks was quite superior.


They resonate, have good SWR bandwidth and generally radiate 5 watts of 
the 100 watts that goes into them. A "magnetic loop" blows it away.  I 
sold the sample Isotron I bought at a hamfest for $5. (Bottom line - 
they are, as we say in the software business, crapware)

This so-called "antenna" is at best dumb, and at worst a rip-off. As

carefully choked so that the coax could not radiate, and working all 
continents with it.


As others have noted, antennas like magnetic loops, loaded whips 
(HamSticks, etc.), and long wires are the weapons of choice with 
limited space and/or requirements of minimal visibility. If the frame 
of the building is non-metallic, indoor antennas can work (but can 
also be mondo noisy on RX). If the frame is metallic, the antenna must 
be outside. The good news is that the building frame will work fine as 
a counterpoise (although it may block the antenna in the direction of 
the building).  A long wire launched away from the building is best -- 
small diameter enameled wire can be hard to see, and works fine as an 
antenna.

Fred,
I had a very similar problem. Exercising the encoder pushbuttons cured the
problem for a while but it came back and I ended up sending it to Elecraft
where the replaced all 4 encoders. I also had the do all the upgrades. Now
it's like a new radio.
