[Elecraft] KPA500 Hum/Buzz

[Andy Durbin]

"my KPA500 seems to have an excessive amount of hum/buzz when transmitting. 
What should I look for?"

Ask Elecraft support to send you the paper "KPA500 Application Note - Hum 
Mitigation".   Also ask about the mod kit that includes a longer transformer 
hold down bolt an extras rubber disks.

[Elecraft] KPA1500 fans

[Dan Atchison via Elecraft]

I have all of the KPA1500 fan mods and firmware upgrades and they make 
the amplifier so much quieter.?? Good job, Elecraft.


What I would like to see, however, is a firmware /option /to exhibit the 
following tendency.


Minimum fan speed at 0.?? When the amp detects a PTT, then the fan speed 
would increase to fan level 1 and remain that way for a period of time 
after PTT detection has ceased (perhaps 10 - 15 seconds?). After that 
delay time it would go back to fan speed 0.?? Of course, temperature 
sensing would increase fan speed regardless of the PTT sense.


If this has been discussed before, I missed it.?? If it's currently 
available then I missed it again.


Awaiting my K4.?? I hate waiting!

Dan -- N3ND

[Elecraft] K3 MACRO'ites please weigh in: Using TUNE while deactivating the KPA500 Amplifier

[Mark Murray via Elecraft]

There's a K3 MACRO hiding somewhere that will, upon pressing of TUNE, 
activate the tune function and simultaneously de-activate the KPA500
amp;

and afterwards, by tapping TUNE, will re-instate the KPA500 amp to its
original
state before TUNE was pressed.  Any ideas on this will be welcome : )

The above relates only to the KPA500 using the recommended K3 connecting
cables.  Thanks.

Re: [Elecraft] Handedness

[Dave New, N8SBE]

Yes, but can you have a dynamic mic plugged into one and an electret mic
plugged in the other?

The K3/K3S has never supported this, and to this day, annoys the heck
out of me, since I have a Heil HC-4 headset (which is dynamic and
plugged in the rear connector) and an Elecraft hand mic (which is
Electret).

I have to go digging through the menus to turn the bias on/off every
time I want to switch mics.  On the plus side, mic HI/LOW gain is
separate for front/rear connectors, but NOT the bias setting.

Hopefully, this has been fixed for the K4.  Separate TX equalizer curves
should be also be supported, as well, along with mic gain, compression,
etc.

[Elecraft] 60 meters

[Fred Jensen]

I loaded the 5 US 60 m "channels" into my K3 frequency memories, with 
VFO A set to CW parameters, VFO B to USB parameters for each one, and 
set to step through the 5 of them when recalled from memory.  It works 
great, just turn the Big Knob to step through the channels ... remember 
CB? ... with one wrinkle:  Moving the BK moves only VFO A, it doesn't 
take VFO B along with it.  The VFO B knob adjusts the frequency in 
whatever steps are set just like all other bands.  The result is that I 
can switch between CW and USB on the channel I originally recalled from 
memory using the A/B switch, but can't if I move VFO A.


Usually, when I discover an unexpected operation like this, there's a 
very good reason why it is so that I never thought of. Does anyone know 
the reason for this one?

Re: [Elecraft] K4 and Linux Infrastructure

[Dave New, N8SBE]

So, let's let the elephant in the room bellow a bit.

Ahem, CYBER SECURITY.

Now that you've put a popular, modern OS in the K4, and hooked it up to
Ethernet (and therefore the Internet), you've just opened a stinking
pile of attack vectors.

And please don't think that no one will bother figuring out how to 'own'
such a powerful connected processor.  If you spend anytime reading up on
things like Distributed Denial of Service (DDOS) attacks, you will find
that things like webcams and routers (which typically don't even have a
32-bit OS in them) have been marshaled to unleash frightening
multi-gigabit attacks on various targets.

Or, try the newest craze, dropping Bitcoin or other digital currency
mining engines on unsuspecting machines, taking them over hog mode, and
pegging the CPU at 100%, using your electric bill for their gain.

Or, maybe the K4 will be the first ham radio to suffer from a
ransom-ware attack, where the poor ham is asked to ante up some ransom
(in bitcoin usually, to make it hard to track) to get control of his
radio back.

True, at least one or more other companies have already stepped out
ahead, by putting Windows 10 in their radio.

I'm just wondering if anyone at Elecraft has been tasked with dealing
with the cyber security aspects of this new toy, and what plans you may
have for outside pen testing, etc. have been made.

At the very least, you should be using authenticated boot and
authenticated flash, protected by a root certificate in an internal
hardware trust anchor.

Re: [Elecraft] K4 and Linux Infrastructure

[Rick WA6NHC]

Much of that protection can be implemented at the router level (>90% of 
all sites) and the internal linux (fairly bullet proof) will deal with 
the radio talking to the world.


It shouldn't be too difficult for Elecraft to refine security to the 
radio, you'd only need a few ports of network access, which if required, 
could be coded to set values (MAC address) up to the menu level...  or 
limited access into the linux side of the radio.


I'm confident it has been considered and managed with the usual Elecraft 
elegance.

Re: [Elecraft] 60 meters

[Rick WA6NHC]

I'm not sure what your question is, can you restate it?

Each of the memories can be programmed so that both VFO (and mode for 
each if I recall, been some years) are set, in this case one VFO for 
USB/FT8 and the other for CW, with their specific frequencies as required.


Then you would simply use the A/B for the mode choice of the moment and 
tap mode if you want DATA A from USB for example.


To change channels, recall another memory slot; correct the mode if needed.

I went a slightly different route, using ten memories, I have each 
channel programmed for a specific mode, "1 CW", "1 USB" etc.  then if 
data, remember that the USB channel is used, but switch to DATA mode.


It would be FAR simpler in the US if the BAND was permitted (as other 
countries allow), not limited to specific frequencies and that would 
also allow simpler contact with other that have different channel 
requirements (yeah, it's become a DX band, duh).


Rick nhc

PS The dual VFO programming in one memory simplifies programming of say, 
6M repeaters where the offset is not a constant (i.e. -500 kHz in CA but 
-1700 kHz in Idaho).

[Elecraft] Using TUNE while deactivating the KPA500 Amplifier

[Andy Durbin]

"There's a K3 MACRO hiding somewhere that will, upon pressing of TUNE,  
activate the tune function and simultaneously de-activate the KPA500 amp;
and afterwards, by tapping TUNE, will re-instate the KPA500 amp to its original 
state before TUNE was pressed.  Any ideas on this will be welcome : )"

I have no idea if it is possible to implement this with a K3 macro but I agree 
it's a desirable feature.  In fact, I have implemented this and more in my 
TS-590/Elecraft controller.

My "KAT500 Tune" function presents a page with selections Check, AutoTune, and 
Save.  

Pressing the  button for  Check sets the KAT500 key line inhibited and 
initiates a TS-590 TX-Tune with 5 W.  Pressing the button again stops TX-Tune 
and re-enables the KAT500 key line.  I use this to check current SWR as 
displayed on my LP-100A and to make manual adjustments to the KAT500 tuning 
solution.

Pressing the button for AutoTune inhibits KAT500 key line, initiates TS-590 
TX-Tune with 15 W,  then initiates a KAT500 auto tune.  When auto tune 
completes the TS-590 is returned to 5 W for TX-Tune, and TX-Tune is stopped.  
When the TS-590 has returned to RX mode the KAT500 key line is re-enabled.

Pressing the button for Save saves the current tuning solution to KAT500 memory.

So, not a macro, but something that should be as easy to implement for a K3 as 
for a TS-590.   Less than $30 worth of hardware and a few hours (days, weeks, 
months..) creating the Arduino code for this and several other functions.

separate for front/rear connectors, but NOT the bias setting.

Hopefully, this has been fixed for the K4.  Separate TX equalizer curves
should be also be supported, as well, along with mic gain, compression,
etc.

Re: [Elecraft] KAT Problems

[Paul Ecker]

Jack & all others that have helped on this question, I posted. Problem
solved. Turns out the issue was a bad connector on a coax jumper running
from my 160M antenna  disconnect switch  to the KAT 500 and  having wrong
antenna selected in radio. Bottom line: KAT500 and KPA500 both working
great now. So thanks again to all for helping. Lessons learned have been
entered in station log.

Re: [Elecraft] K4 and Linux Infrastructure

[Paul Gacek via Elecraft]

Dave

DDOS is quite hard for any end point (PC, iPhone, K4 etc) to deal with 
effectively. If a million zombie Macs decide to simultaneously attack your end 
point your best chance is as Rick states, a device that makes up the perimeter 
defenses such as a firewall or cyber security alternative (i.e router, IDP). 
Most homes don’t have anything particularly sophisticated deployed and are 
therefore somewhat vulnerable. In truth DDOS attacks are quite rare and 
typically not aimed at Citizen Dave or his neighbors. Protection albeit 
optimistic is really in the realm of a corporate network but even then we have 
a few cases where iconic sites get hammered and go dark. Enabling the K4 to 
defend against DDOS is a little like building a house to withstand random bits 
of ISS dropping in unexpectedly; not something I’m expecting to be paying for.

Unwanted ransomware or bitcoin mining programs are most likely the result of an 
unwitting end user at and end point (PC, Android etc) doing something that 
resulted in the malware ending up on their end point. Could be surfing to a 
suspect web site (www.PawnStorm4U.com ) or even 
going to a compromised but reputable site such as NASA.gov .  
Alternatively, it could be someone opening a compromised PDF or Word/Excel 
attachment. The best protection here is to be cautious and mindful of what you 
do in the cyber world and absolutely make sure you are running the most 
uptodate OS (not XP) and to its most current patch level. 

Presumably but maybe not, the K4 won’t make available to the ham operator a 
browser that allows them to surf wherever nor an email client that they can 
read Excel attachments at the whim of the ham operator. That is best done 
outside of the K4.

Hardening Linux, following best practices on coding and penetration testing are 
all things to be aware of and implement as appropriately.

Re: [Elecraft] K4 and Linux Infrastructure

[Dave New, N8SBE]

Paul,

I believe you mistook the 'direction' of DDOS attack I was talking
about.

The K4 would not be the target of a DDOS attack, but rather an unwitting
participant in launching a DDOS attack as part of robot army of IoT
devices.

Thousands of hacked IoT devices are for rent on the dark web, for any
script kiddie that wants to attack a particular target.

Also, it may be popular to use hacked web sites, or various documents
with trojan horse loads to deliver ransom ware or bitcoin miners, but
there are other known vectors, including various open ports found while
scanning.  It may be the a router would be able to block access, but the
very peer-to-peer nature of the K4 (controlling other K4's or being
controlled by another K4 or PC, tablet, etc, means that routers would
need to allow certain inbound connections through the router or
firewall.  These allow for interesting attack vectors, which will
certainly be exercised, if possible.

73,

Dave,

It does remember the settings on a per jack basis - at least mine does. 
You just change the MIC SEL menu from front to rear when switching.  The 
gain and bias settings should remain the same.


Some hams don't like to explicitly enter the menu, but prefer to assign 
it to a PF key.

Re: [Elecraft] K4 and Linux Infrastructure

[Jeff Scaparra]

Actually there is more to think about than security here as well. What
would elecraft do about users that break the system but misconfiguring
stuff, etc... if they allow users to opt in I would fully expect users to
have to agree to owning responsibility for any modifications. This would
mean that if you have a problem with the radio and send it in and the
problem is solved by reflashing the base image then you should be charged
for wasting their time. I would also expect to have the base image given to
users so we can fix our own mistakes.


I think this problem will exist one way or another. Quite likely elecraft
will be legally required to make available some or all of the base image of
the radio due to software licences. It is also likely that someone will
figure out how to get access to the underlying system. In my opinion
elecraft can get out in front by setting expectations and telling users if
you do this your on your own from a warranty perspective. It would be nice
of them to limit that but they could have that void the whole warranty.

It will be interesting to see how they handle this. This is precisely the
reason I got put my deposit for the second group. I want to see how this
shakes out before commiting which means I cant be the first one with the
radio.

I'm not sure what your question is, can you restate it?

I'll try although it wasn't a question, it was an unexpected observation.


Each of the memories can be programmed so that both VFO (and mode for

USB/FT8 and the other for CW, with their specific frequencies as 
required.
Yes, and very thoughtful of Wayne.  That's exactly what I did.  In 
addition, I set the "channel hopping" mode ["*" in the name IIRC] for 
the 5 of them so that once recalled, the Big Knob jumps through each of 
them meaning you don't have to recall the next one, it's automagic ... 
for VFO A at least.


Then you would simply use the A/B for the mode choice of the moment 
and tap mode if you want DATA A from USB for example.
El Correcto ... at least that was my plan. Unfortunately, when I channel 
hop to the next one with the BK, VFO A hops very proficiently, however 
it doesn't drag VFO B along to the next channel with it.


To change channels, recall another memory slot; correct the mode if 
needed.
That's what my slick little scheme was supposed to avoid -- having to do 
a recall [tap M>V, select, tap M>V]


I went a slightly different route, using ten memories, I have each 
channel programmed for a specific mode, "1 CW", "1 USB" etc.  then if 
data, remember that the USB channel is used, but switch to DATA mode.
That works too, and it's not like I'm going to run out of memory slots, 
and if all 10 were placed into a channel hopping block, you can move 
from one to the next with the BK only.


It would be FAR simpler in the US if the BAND was permitted (as other 
countries allow), not limited to specific frequencies and that would 
also allow simpler contact with other that have different channel 
requirements (yeah, it's become a DX band, duh).
Well, 60 m is what it is worldwide and being one of the regulators is 
way above my pay grade.  A great number of countries have allocated the 
WRC-15 decision of 5351.500 - 5366.500 KHz [15 KHz] which overlaps the 
US "Channel 3" at 5358.500.  At WRC-12, 5250 - 5450 was originally proposed.

users so we can fix our own mistakes.


I think this problem will exist one way or another. Quite likely elecraft
will be legally required to make available some or all of the base image of
the radio due to software licences. It is also likely that someone will
figure out how to get access to the underlying system. In my opinion
elecraft can get out in front by setting expectations and telling users if
you do this your on your own from a warranty perspective. It would be nice
of them to limit that but they could have that void the whole warranty.

It will be interesting to see how they handle this. This is precisely the
reason I got put my deposit for the second group. I want to see how this
shakes out before commiting which means I cant be the first one with the
radio.

Re: [Elecraft] K4 and Linux Infrastructure

[Al Lorona]

 You guys have now reached the scenario I was trying to ask about last week, 
but obviously didn't make myself understood.
When I asked if the K4 would be able to 'talk to the outside world', I meant an 
ability to initiate communications with a web site, a server, or something else.
Yes, allowing users to get down to the operating system would probably be 
unmanageable. But what about loading 'apps', in the same way that you install 
apps on your phone? I could see a logging app, a reverse beacon app, or 
something else that would add real functionality to the radio. I'm sure that's 
been talked about... and I wonder what the thinking is along these lines.

Re: [Elecraft] K4 and Linux Infrastructure

[Dave Cole (NK7Z)]

Based on the lack of ability to chance the CW rise times, I suspect 
Elecraft will not give access to the processor, and OS.  I would not.


Why?  If too many users change things, and break things, the radio will 
get a bad rep...  If Elecraft is smart, they will lock the users out of 
that level of access.

DDOS is quite hard for any end point (PC, iPhone, K4 etc) to deal with
effectively. If a million zombie Macs decide to simultaneously attack
your end point your best chance is as Rick states, a device that makes
up the perimeter defenses such as a firewall or cyber security
alternative (i.e router, IDP). Most homes don’t have anything
particularly sophisticated deployed and are therefore somewhat
vulnerable. In truth DDOS attacks are quite rare and typically not aimed
at Citizen Dave or his neighbors. Protection albeit optimistic is really
in the realm of a corporate network but even then we have a few cases
where iconic sites get hammered and go dark. Enabling the K4 to defend
against DDOS is a little like building a house to withstand random bits
of ISS dropping in unexpectedly; not something I’m expecting to be
paying for.

Unwanted ransomware or bitcoin mining programs are most likely the
result of an unwitting end user at and end point (PC, Android etc) doing
something that resulted in the malware ending up on their end point.
Could be surfing to a suspect web site (www.PawnStorm4U.com) or even
going to a compromised but reputable site such as NASA.gov.
Alternatively, it could be someone opening a compromised PDF or
Word/Excel attachment. The best protection here is to be cautious and
mindful of what you do in the cyber world and absolutely make sure you
are running the most uptodate OS (not XP) and to its most current patch
level.


Presumably but maybe not, the K4 won’t make available to the ham
operator a browser that allows them to surf wherever nor an email client
that they can read Excel attachments at the whim of the ham operator.
That is best done outside of the K4.

It's an embedded system.  If you break it, you own both parts, and

Missed reply all.

At some level even if they do "only" have apps they will have this problem.
App developers will need to be able to modify and test things. Also I doubt
that there would be many apps if this is a separate process than mainstream
linux/windows. why would a hobby developer want to build a separate thing
just for one pretty expensive radio when they could just build the app for
linux or windows and support everyone.

Maybe they have some trick to make app onboarding easy.

Re: [Elecraft] K4 and Linux Infrastructure

[Leroy Buller]

Interesting discussion.  I think and surmise that the engineers at Elecraft
had to put in a pretty powerful OS and processor to do all of what they
want to do in the box.  Especially with 4 RX in the box plus all the other
things it will do.  But, besides the issues mentioned in this thread  it is
exciting what the possibilities are with the CPU in the box.  I think it is
ingenuous.

Re: [Elecraft] 60 meters

[K8TE]

While you can scan or dial through VFO A, once you "land" on a particular
channel, the VFO B frequency and mode associated with that channel is
available by using the VFO A/B button.

I originally loaded the 60m CW frequencies in VFO A for my 60m channels
since I'm more likely to use them working SOTA activators.  However, I
usually scan the SSB channels.  Thus, I swapped between VFO A and B so I can
scan USB channels and select the appropriate VFO B CW channels when needed. 
This comes in handy when someone suggests 60m for USB or when I see a SOTA
dude spotted on 60m CW.

Re: [Elecraft] K4 and Linux Infrastructure

[Fred Jensen]

Well, all good discussion, but I advise that you do not hold your breath 
for "open firm/software in the K4," or basically any access at all.  
It's just beyond what any manufacturer can do.  I suppose Eric, who is 
noted for his business skills, could start up an "E-tunes" app store for 
the K4, with developer standards, testing, and the like.  I doubt that's 
remotely close to the top of his To-Do list however.


Having just had my 79th birthday yesterday [thanks for all the HB's!], I 
remember when Heath came out with an analog computer at what would have 
been the beginning of the "Science Hobbyist" revolution.  Without the 
Internet, there were no Email lists of course, but the number of "I did 
this and it didn't do what I expected" inquiries was way more than they 
expected.  Fortunately [for Heath] the customer base was very rapidly 
exhausted and the Heathkit Analog Computer silently sailed into the sunset.

At some level even if they do "only" have apps they will have this problem.
App developers will need to be able to modify and test things. Also I doubt
that there would be many apps if this is a separate process than mainstream
linux/windows. why would a hobby developer want to build a separate thing
just for one pretty expensive radio when they could just build the app for
linux or windows and support everyone.

Maybe they have some trick to make app onboarding easy.

Seriously folks, think about the folks in Elecraft support and Service.

Imagine spending an hour working through a problem just to find out that 
someone is running modified firmware (and this is firmware, not software 
for us to play with).

It's an embedded system.  If you break it, you own both parts, and 
Elecraft would need a 100% reliable way to verify that you didn't 
introduce bugs.

Let this idea go, folks.

Re: [Elecraft] K4: panadapter directional coupler required?

[Marty Koszewski]

Hi Brian,
I understand that the panadapter is built in to the K4.  

The directional coupler added additional functionality to the P3.  It gave real 
power output and SWR,  as well as an output waveform.  All functions I use 
today.  I was wondering if that functionality is avail in K4 since there is no 
input from the feedline if using an amp or external tuner.  

Thanks.

Re: [Elecraft] K4 and Linux Infrastructure

[Eric Swartz - WA6HHQ, Elecraft]

I apologize if we have created any confusion on this topic.  (Yup - we have been 
a little busy as of late with the K4 introduction ;-)


To be clear - we do not plan on granting open access to the main CPU or K4 
internal operating system. That would be a impossible situation to support and 
it would significantly impact product stability.


At this point, any additional internal software applications developed for the 
K4 will be coming via Elecraft.


Of course we will certainly will have a robust external API for the K4.

In the interest of reducing list bandwidth overload, lets end this thread at 
this time.

Why?  If too many users change things, and break things, the radio will get a

The K4 has internal and external TX waveform monitoring built in. It should 
directly support any amp that has a TX sample output, such as the KPA1500.

[Elecraft] portable antennas and rigs going through airport security

[Dave Sublette]

All this talk about the AX-1 has stirred me up.  My wife and I fly to Utah
once or twice a year to visit grandchildren.  I have a KX3.  Although I am
sure the AX-1 is a nifty and convenient antenna, I had stuff laying around
here, so I built a portable antenna that collapses into a 2 foot length/.
It will fit in my carry on.

My wife and I require wheelchairs when we travel, for valid reasons which I
don't need to discuss here.  We always get the red carpet treatment.  Since
we are both over 75 -- no shoes off, etc.  They put us right through
security.

So --- what should I expect with a KX3 (no batteries), portable antenna,
and a small power supply as we go through?  Your experience will be helpful
to know.

If it looks too hairy, I can just mail them to our son's house.

Re: [Elecraft] portable antennas and rigs going through airport security

Dave,

I used to take an FT-817 and wire antenna through airport security (TSA)
when I travelled for work. Never had an issue. Put it in your carry-on, and
let TSA inspect it if they check your bags. You may actually want to leave
the battery in, in case they ask you to turn on your rig.

Re: [Elecraft] portable antennas and rigs going through airport security

[charlie carroll]

Dave:
For the most part I get through security without any problems.  I just 
did a round trip to PJ4 and no one in security seemed to blink.  IMHO, 
it really depends on the person running the xray machine.  Last year I 
had a 1500 watt amp and K3 with me, and neither was even opened.  If 
anything, keyer paddles, at least those with a heavy brass base, seem to 
catch their attention. Wires, coax, fishing reels, big variable 
capacitors, all didn't get a blink of the eye.  However, last year I did 
lose a drill index in a carry-on to security.  Some other tools can be 
an issue.  Oh, last year I had a freeze bag full of adapters that caught 
their eye.  One year I even carried my K3 in my back pack. They wanted 
to know what it was, took a look, and then put it away.


IMHO, keep any sharp objects in your checked baggage and don't lose any 
sleep over it.

Re: [Elecraft] K4 Production Prognosis

[Richards]

What K4 features and capabilities remain under development, and what 
features are already developed and cast in stone?


Will all features and specifications described in the product brochure 
be viable and fully functional on the first production units?


How long will buyers wait to buy one, if they do not buy in early and 
advance a capital development loan?


Will all three models be available in the first production run?

Will all pre-orders ship in the first production run?   If not, how long 
until the second run?


How definite is the promised Late Nov/ Early December 2019 release data?

Re: [Elecraft] portable antennas and rigs going through airport security

[Al Lorona]

 I am sure there are just as many horror stories as "I've never had a problem" 
stories. Such as the time I was carrying a small Ten-Tec shortwave receiver and 
was detained for almost half an hour while the agent stared and actually asked 
me, "Voices come out of this thing?"  

Meanwhile, an alarm blared for several minutes without any response from TSA 
whatsoever. Someone could have gained access to the tarmac in that time and 
planted a bomb. But the little Ten-Tec was deemed more of a threat.
Be prepared for any response, subject to the whim of the agents.

Your biggest concern is the total wattage of the battery.  Check the web
site for your carrier and the norm is about 50 watts total capacity.

More than a few contesters drag radio gear several times a year to 
island stations in the Caribbean. One of my neighbors, W0YK has long 
carried on a pair of K3s in Rose's cases to P49, where he regularly wins 
RTTY contests. He had Rose put velcro on one surface of each so that 
they "clamped" together to be one piece of luggage, then pulled them 
apart to stow them in the overhead.

Re: [Elecraft] K4 Production Prognosis

[David Gilbert]

You're asking for concrete answers to questions Elecraft has already 
stated for the most part are not yet final.  Stuff like that is what 
makes companies wait until everything is nailed down before saying 
anything.  They said November was the target, and they called it a 
target because everything ISN'T nailed down yet (they NEVER called it a 
"promise").  How is that not pretty clear?

Will all features and specifications described in the product brochure

How long will buyers wait to buy one, if they do not buy in early and 
advance a capital development loan?


Will all three models be available in the first production run?

Will all pre-orders ship in the first production run?   If not, how 
long until the second run?


How definite is the promised Late Nov/ Early December 2019 release data?

Re: [Elecraft] K4 Production Prognosis

[Nr4c]

Good grief!

This is computer hardware and software. A business where “before end of year” 
really means 2 hours before midnight. 

And the “First Quarter” runs until May or June. 

Don’t look for all the features to be fully implemented on first delivered 
radios. Even the K3S is still a work in progress!  

About “Production Runs”

Elecraft is a small company. They will prob build 25 or so radios for field 
testers. This will allow some training for the small staff of assemblers. 

Once they are satisfied with the product, they will begin assembling the first 
radios. These builders are not robots. But humans who must go thru the process 
of building a kit, without the “assembly manual” and it takes time. Once built, 
it goes to the burnin rack where it will sit for up to 24 hours being tested 
and evaluated. Now to packing and shipping. This “run”, one radio. The first 
week may see a dozen radios out the door.  It slowly grows from here. 

I’ve waited in line for a KX3, a PX3, and K3S. 

I visited the “plant” a few years ago and spoke with a K3 builder. He said he 
could build a K3 in under an hour. But he’d built maybe a thousand by then. And 
the parts were all there in bins around his work area.
