Your point is certainly well taken.  Performance enhancements, new features, 
bug fixes, etc. are all possible given the old adage, “It is simply the 
software.”

That said, exactly how a product line evolves over time can have a huge impact 
on both current customers and perspective customers. One can certainly argue 
that those that jumped in line on the day of product announcement for the K4 
are ‘early adopters’ who are willing to purchase a hardware design and then be 
relatively patient waiting for the software/firmware to evolve to the point 
that announced features are made available.  The tradeoff is that ’needed 
features’ may lag behind the ‘basic features’ and that those that forked out 
real  for the latest generation of hardware may start to get ‘antsy’ about 
not being able to take full advantage of a product’s “potential” as 
software/firmware evolves later.  

While I have no idea what Elecraft’s development timeline looks like, 
presumably their development schedule is predicated on relative priorities as 
well as creating the building blocks necessary to enhance the software over 
time.  I also don’t know how large their development team is or whether they 
have other duties/responsibilities as well.  As far as I know, they have not 
released a ‘development roadmap’.  Bottom line is that those that purchasers of 
a new generation of hardware that is fully dependent upon software to ‘make the 
magic’ must recognize that such development work will likely exceed their 
presumptions of how quickly such software is fully developed.

While Elecraft is not FlexRadio, one only has to look at the history of Flex to 
see how much longer software development takes over hardware development to 
create the ‘desired’ product.  When Flex announced their 6 series at the 
2012 Hamvention, they delivered the hardware within 18 months of product 
announcement to those who ’signed up’ in the first few months after product 
annoucement.  I received my Flex-6700 in November 2013 with SmartSDR for 
Windows version 1.0.  However, the first iteration of SSDR (v1.0) was simply 
the first step in a long evolution of software development.  It wasn't until 
May 2017 (five years after initial product announcement) that “SmartLink” was 
introduced in SSDR v2.0 that allowed remote connectivity of Flex-6 series 
transceivers, a product feature announced in 2012 and which is why I got the 
Flex-6700 in the first place.  

Almost 10 years later, we’re now seeing hardware issues starting to crop up 
with the SD cards installed in older Flex-6xxx transceivers that contain the 
“smarts” of these products.   While Flex utilizes ‘industrial grade” SD cards, 
even these products apparently degrade after years of read/write cycles.  
Customers are now experiencing issues where current firmware upgrades ‘brick’ 
their transceivers because of the longterm degradation of these cards means 
they fail during testing of SD card performance as part of the firmware update. 
 In other words, the testing is done to ensure that SD card is capable of 
accepting the new firmware and fails.  Flex has been very responsive is 
supplying replacement SD cards (even though radios are beyond their warranty 
period) which is certainly appreciated, but it does leave a “taste in one’s 
mouth” when this happens.  BTW, these SD cards are unit specific (they 
apparently contain serial number information) which means one can’t simply copy 
the contents of one SD card and install it on a non-Flex provided SD Card.  

I note this simply to point out that today’s world of “software defined radio” 
introduces not only new capabilities but also changes the paradigm about 
product development and longevity of products due to limitations.   Indeed, 
investing in a new product release such as the K4 or the Flex-6 means that 
the purchaser becomes part of that product’s ‘ecosytem’ where it may take a 
significant amount of time to finalize that ecosystem.  This compares to the 
‘old days’ where one purchased a ‘radio as is” with limited update capabilities 
and one simply purchased a replacement as needed.

[Elecraft] Elecraft CW Net Report

[kevin]

Good Evening,

   The bands were so so.  QSB from S0 to S8 at times, with waves of 
noise.  The sun has been up to something.  It did show up for a few 
minutes, now it is gone again.  Spring arrives slowly here. Trilliums 
are blooming in the warmer spots.



  On 14050.5 kHz at 2200z:

W0CZ - Ken - ND

K4JPN - Steve - GA

K6XK - Roy - IA


  On 7047.5 kHz at 2330z:

WM5F - Dwight - ID

K6PJV - Dale - CA

K0DTJ - Brian - CA


   I started watching Harvey over dinner.  I thought a Pooka was 
seasonal, but Jimmy Stewart brings him to life.  Movies were different 
in 1950.  There was no CGI of a 6' 3 1/2" tall rabbit. Nor was there any 
color.  Just a good story.



Until next week 73,

   Kevin.  KD5ONS

Re: [Elecraft] K1 accessories

[Don Wilhelm]

Chris,

That is quite feasible - getting a board is the starting problem.

If you can find a 2 band board for any band(s), you can order the 
crystals for the bands you want from Elecraft.
They may also have the K1 band kits in stock which have the capacitors 
required for that band.  Worst case, you may have to order the 
capacitors separately if Elecraft no longer has the K1 band kits.
If Elecraft no longer has the crystals, you may have to order custom 
crystals - they must be fundamental mode crystals - overtone mode will 
not work properly.
See the K1 band kit instructions for the components required. Download 
the instructions from Elecraft website.

There are a few of those around now. Of course they have varying capabilities 
relative to SMD. A buddy of mine just recently had a K3 repaired by N3CZ over 
in North Carolina. He turned it in a few weeks.

There is a business opportunity here for someone with the HF transceiver
diagnostic and SMD replacement skills and equipment.

Someone who does excellent Elecraft service work at reasonable prices would
never want for business.  And if the work is of consistently high enough
quality, perhaps Elecraft would designate them as an Authorized Service
Center.

I agree with Chuck that the K3 series are dead ends in the sense that no
more development effort will be put into them.  Sad but true.  There are
some aspects that I'd like to see improved in the firmware but it simply
is not going to happen.  As fine of a radio as my K3 is, Elecraft has
moved on.  That is the reality.

It is also a reality that my K3 continues to perform as well as it ever

I don't think it has much if anything to do with the size of Elecraft.
WW2 gear was built with point-to-point wiring and components [e.g.
resistors, capacitors] that were available through the 40's, 50's, 60's,
70's,  80's, and even into the early 90's.  My Swan 500C in the late
60's was still wired point-to-point. You could buy a .01 mfd capacitor

later it might be a disc ceramic with two leads maybe a little smaller
but still visible.

Technology made a sharp turn as silicon replaced nearly everything and
"Honey, I shrank all the parts" became a great hit at the box office.
And, the availability life of the nearly invisible parts decreased
dramatically. More and more function was being crammed into less and
less space, and the individual parts did far more than just provide
capacitive reactance.  Many multi-functional things you could buy
readily in early 2000 were closing in on unobtanium before the the end
of the decade. It's affected everything and everyone, it will probably
continue, and Elecraft is caught in it just like everyone else.

Re: [Elecraft] Sherwood Receiver Tests

The K3s and the K3 with new synths aren't "dead ends".  The great 
majority of specs for both rigs are better than the K4 and will be until 
the K4HD comes out at three times the price.  The K3 and K3s are only 
"dead ends" because of a business decision, not a technical one.

unfavorably with the lowly IC-7300. But the K4 will someday possess
predistortion and consequently a pristine transmitted SSB signal. Unlike
its predecessors, the K4 has an unlimited future. That's the nature of a

Re: [Elecraft] IndeIdefinate support for K3s?

[David Gilbert]

That window is closed.  Elecraft offered a last time buy of modules for  
the K3 and K3s some time ago.  They hinted that they might have made a 
few extras, but for the most part what you have now is what you (or 
someone else) will have forever unless you buy a spare rig for parts.


That's not the scenario Elecraft originally promoted when I bought my 
K3, but they clearly decided they couldn't do that and support the 
ongoing effort on the K4 at the same time.  Parts are obviously still 
available for the modules and accessories for which they accepted last 
time buy orders ... they just decided not to make any more after that.


I guess one way to look at this is that Elecraft is a small company that 
outgrew its ability to do everything they said they would. 
Understandable maybe, but unfortunate.

How long will elecraft continue to support the case 3s and are there any

Re: [Elecraft] Indefinite support for K3s

[Michael Carter]

Wayne, N6KR, posted on 23 April that Eric (WA6HHQ) will
have an update on K3 modules 'next week.'

My recollection is that Elecraft set a cutoff date in spring 2021
for ordering of K3/K3s modules to gauge interest and allow
ordering of long-lead-time parts.

I can't find another recent post in which it was said that
there may be a few 'spares' of select K3/K3s modules
available for those who did not order them in spring 2021.

Mike, K8CN

I can't speak for Elecraft but given the present disruptions in parts,
supply chains and labor, coupled with inflation, I have to wonder how they
could possibly give an answer other than "as long as possible."

Something you might consider (maybe you already have) is buy a backup K3S to
serve as a donor if something goes south with your main one. There are loads
of them coming on the market now, and if you already have a working one, you
have more time to hold out for a good price on a second one. This is exactly
what I did for an Omni D recently. It's great peace of mind for when
something goes wrong (when, not if :)

How long will elecraft continue to support the case 3s and are there any 
components or modules that we should buy in advance because they won't be
