Re: [Elecraft] User's Dilemma

[Doug Turnbull]

Dear OMs,
 The problem is that radio prices would almost certainly need to go up
to give the dealer a margin after his/her own expenses.

   An independent service facility would be nice but is there adequate
business in this?Not so sure we in EI could easily use a UK service
facility.   I prefer to ship to California than Italy.  The cost of
shipping to Italy may not be so wildly different than the cost of
California freight.  Have a friend who lost a SPE 2K FA in shipping to Rome
and received no compensation.

 It is a problem for sure. I have always dealt directly with the
factory and have been fortunate.A conundrum for sure.   Enjoy your
Elecraft.   Be careful and pray.

Re: [Elecraft] Overseas distribution and service?

[Doug Turnbull]

Dave,
The radio is modular so quite possibly the entire radio would not
require return.I have found Elecraft support superlative.There are
also repair services available in the EU.Perhaps just as EI dealing
with UK  our natural provider in the past is awkward; it is equally
difficult for G to work with the EU.


 For many years there was no UK supplier of Elecraft but the K3 was
still a seller.   Personally I prefer ordering direct from the factory.
 It seems a less expensive route than having a middleman.

 The products are dear though and I wonder how long it is before China
takes over. The QRP and SOTA market has a lot of low cost product.
 Perhaps signal purity is down but so too is cost.There are challenges
in free trade.

Enjoy your radios.Pay me no heed.

Re: [Elecraft] Buying a K4 in UK

[Doug Turnbull]

Geert,
As a many time direct purchaser, I can say I never experienced any
horror story or great difficulty in direct orders to Elecraft shipping to
EI via UPS, who handle all paperwork and charges.   I must have ordered on
ten different occasions.Me thinks you paint to grim a picture.

  I prefer to deal direct with Elecraft in fact.   To each their own
but again there is little need for such angst in my experience.

Re: [Elecraft] Buying a K4 in UK

[Doug Turnbull]

Dear OMs,
I previously replied to this post so will not repeat myself.I
needed to return a KPA 1500 to Watsonville, Ca.   It was determined that
only the RF deck was required.I shipped FedEx by their premium shipping
method and had no difficulty.It went straight through as a repair.   No
added charges in my case.   The amp was out of warranty so of course
service was charged for.   US and EU repair costs, I suspect are not far
out of line.

As an aside I included a Samsung Smart Tag similar to an Apple Airtag and
thus had additional reassurance.   Not sure shipping to CA cost all that
much more than Italy.   Had my amp back within about a month.

Elecraft can also dispatch sub-modules if there is a failure.On line or
telephone support was excellent earlier in sorting a friend's K3.   Do not
be too worried about service.

Re: [Elecraft] [Elecraft-K4] KPOD intermittent

[Doug Turnbull]

Jim,

 I have two K-Pods which are used with my K4Ds and previously K3s.
I too on occasion have trouble with the switches. I have noted that
rebooting the K4D will often cure the problem.Also I wonder if having
the switch react to both momentary tap and sustained push beyond a second
or two helps.For me the radios would not be the same nor nearly as
ergonomically friendly without the KPods and both of mine go back to the
beginning of the KPod era. I too would be interested in hearing more
but I will keep my KPods.

I really like the KPOD...when it works.



I find the buttons occasionally non responsive resulting in nothing being
sent. After a few taps it eventually works again for a while.



Of course this mostly occurs when trying to send a call in a pileup or a
reply 599TU.



Is this a button thing that needs replacing or something in the K4 being
non responsive?



I think it's the KPOD itself since it also happened on my old K3S.

Re: [Elecraft] East Coast Service

[Doug Turnbull]

Dear OMs and YLs,
 I live in EI but also have roots in New England.Just returned my
KPA1500 for service - probably the finals.   TG I have two of this fine
amp.I sent it to CA rather than Italy as the real knowledge base is at
the mother ship.Using UPS it took three days to arrive.If living in
States again and having a choice it would probably still go to CA.   If in
the same State then sure I would drive to the repair centre.   Distances on
the east coast can be significant.

 We are all different but for me the mothership is where I want my
Elecraft radios to go.   That is the centre of knowledge and expertise for
the big E.   My two cents and not worth anything these days.I see your
point as well.

Re: [Elecraft] K4 production software release (R32) now available

[Doug Turnbull]

Wayne,
You and your crew at Elecraft are champions. Thank you.
   73 Doug EI2CN

-Original Message-
From: elecraft-boun...@mailman.qth.net 
On Behalf Of Wayne Burdick
Sent: Wednesday 14 December 2022 20:59
To: Elecraft Reflector 
Subject: [Elecraft] K4 production software release (R32) now available

Release 32 has been beta tested (R32.BETA2) and has now been moved to
production status.

See release notes below, or on our K4 software page, or view them in the
updater on the K4 itself. (For your convenience, the list below shows all
significant changes since production release 31.)

Software development is continuing in multiple areas, including remote
control.

73,
Wayne
N6KR


* * *



 R32 (PRODUCTION) ==

December 13, 2022


- SSB/ESSB TRANSMIT AUDIO LOW-FREQUENCY RESPONSE IMPROVED:  The nominal
SSB transmit audio low-frequency rolloff can now be moved down from about
200 Hz to 100 Hz. (Amplitude at 100 Hz then increases by nearly 20 dB.)
This selection is made using the new "TX Audio LF Cutoff, SSB" menu entry.
IMPORTANT NOTES: (1) The 100 Hz selection is *always* applied in ESSB
mode. (2) In addition to using this new SSB setting, you can control the
transmit passband in all modes using TX EQ. (3) If you use USB or LSB for
audio DATA modes such as PACTOR that require fast turnaround times, you
should not use the 100 Hz SSB setting, because it slows turnaround by
about 20 milliseconds. (The high-performance digital filter required to
obtain a lower passband has additional "taps," resulting in greater
delay.)

- KPA1500 / KPA500 LOSS OF BUTTON PRESSES:  In previous releases, some amp
front panel button presses could be missed by the K4 due to the concurrent
handling of other band-change activity.

- RADIO LOCKUP DURING VFO MOVEMENT AT ~5600 KHZ:  One operator discovered
a radio lockup when moving the VFO in the vicinity of 5600-5620 kHz. This
was due to incorrect lookup of ATU LC segment data, which has now been
corrected.

- TERMINATION OF DVR MESSAGES no longer causes occasional loss of mic
audio.

- REPEATER OFFSETS are now correctly applied to VFO B when in SPLIT.

- IMPROVED EEPROM DATA VERIFICATION.



FOR SOFTWARE DEVELOPERS & MACROS


- The "TQX;" command now bypasses other command processing delays to
provide a more real-time response during "TX;" / "RX;" command
transitions.

- DUPLICATE "TX;" COMMAND while in transmit mode no longer exits transmit.

- ADDED "EE0;" command to reset all radio state and menu parameters to
defaults, with the exception of factory calibration data.

- ADDED "TQX" GET COMMAND (extension to "TQ" TX status query):  If the GET
query is "TQ;", then the K4 is considered to still be in transmit mode
during the S-meter holdoff time (300 ms), even though receive audio can be
heard. If the GET query is "TQX;", then the S-meter holdoff time is not
considered to be part of the transmit state. This allows an application to
find out more quickly when actual RF transmit has ended, which may result
in a more responsive user interface (when playing DVR messages, for
example).

- ADDED "AG$+nnn" (AF gain increment/decrement).

- ADDED "VC" command to properly handle configuration of per-mode coarse
tuning steps. "VT" command also improved to correctly handle A/B VFO
swaps, etc.

- IMPROVED "#HWFC" command to allow modification of waterfall color mode
for both panadapters on the external monitor.

[Elecraft] KPA 1500 Status message %

[Doug Turnbull]

Dear OMs and YL,

 Can someone please tell me what the % sign with Status message of say
67% indicates. I think it is the efficiency of the amplifier at a given
point.The same Status screen displays: forward power, Voltage, Current
and temperature as well as the % figure. I looked through the manual but
can not find the answer to my question.  A quick calculation seems to
indicate it indicates power out to power input. Thank you.

Dear OMs and Yls,

   This is a link to a most interesting, thorough interview with Wayne
N6KR regarding the Elecraft design philosophy, entire Elecraft range and
field operations. It takes one hour and forty minutes to view in
entirety but believe me is worth the time.Do it in bits if you must or
on the floor as I do exercising to avoid the back surgeons knife.I
cannot recommend this YouTube interview, "Elecraft on Coffee and Ham Radios"
highly enough.

[Elecraft] K3 & KPA1500 ERR KP 1

[Doug Turnbull]

Dear OMs and YLs,
  Can someone please advise me as to what ERR KP 1 indicates.Using my 
K3 and KPA 1500 on Six meters FT8 I get this message only while transmitting on 
the K3 screen with no indication of a problem on the KPA 1500 . If I place 
the KPA 1500 into standby mode the message does not appear.I do not use 
ALC.There seems to be no reference to this error message in either manual.  
 The amplifier seems to be working just fine.

If I lower the K3 drive (8W) drive to the amplifier so that the K3 KPA internal 
amp is not engaged but the KPA 1500 is in operate mode, the problem does not 
occur. Should I increase the power to 12 W from the K3 with KPA 1500 in 
operate mode the error code does appear.Again the KPA 1500 seems to operate 
perfectly.The K3 at 95W with KPA 1500 in STBY does not result in the KPA 1 
message.

What does ERR KPA 1 indicate on the K3 screen?

 Thank you for your help.

In the Config Menu:

PWR SET
If set to PER-BAND, the power level is saved on each band. 
This is especially useful with external amplifiers. 

Mine is set to PER-BAND.

If a KPA500 is connected to the K3S via the ACC cable (as mine is), two sets of 
per-band power settings are saved: one for “barefoot” operation, one for use 
with the amp.

Where and how do I save and then access these two savings? Are the somehow 
automatically selected?

In my case I want to save 100 watts for "barefoot" operation and 25 watts for 
amplifier operation. I've tried using Quick Memories 1-9 for bands — which 
works fine — and Quick Memories  M1 and M2 for the two power settings for each 
band — which does NOT work.

What's the right way to do this?

Re: [Elecraft] Signals wild...signals caged

[Doug Turnbull]

Wayne, 
 Nicely put and so true.However as I remember the Novice bands were
a zoo, General class operators avoided us.A CQ could go on for several
minutes but it was a fun playpen.Wow staying up to 2 AM could yield a
QSO in Oklahoma all the way from Virginia on 40M.That was a QSO you
could brag about.   My surplus TCS rig would not go onto 15M so real DX was
pretty much out for the first two months of my Novice ticket, then the
General Class exam was passed and what a difference. They were good days
but the chirp is well left in the past. 

  Yes we need to return to the true path of CW, FT8 is a drug and
makes many of us lazy, mea maxima culpa.   Thank you Wayne.

Subject: [Elecraft] Signals wild...signals caged

My son is an avid birdwatcher. As his understudy, I've learned the names of
the birds that hang out in our yard and gather at local wetlands.

On a recent walk we saw one of our favorites, an American kestrel, a small
raptor that terrorizes lizards and mice in the foothills on both sides of
the San Francisco Bay. The bird's coloration is a surprising mix of blue,
brown, orange, yellow, and white, adorned with an array of black dots.

Finding a kestrel in the wild is like stumbling upon a rare gem, lying on
the ground.

The bird reminded me that when I was a kid, I often hunted for gems of a
different sort: DX. I was a novice, and in the early 1970s, novices were
limited to working DX Of The First Kind. CW. 

Like brightly colored birds, each CW signal arriving from a distant land was
unique. 

Several factors were involved. In those days most ops used bugs or straight
keys, so each operator had an identifiable fist. Rigs were not as stable as
they are now, yielding timbres with a motley mix of buzz, drift, and chirp.
Add fading and noise to the mix, and you had no shortage of audible
intrigue. 

In fact -- trust me on this one -- RST reports haven't always ended with a
dependable "9." I once gave out an RST of 332. I'll never forget that poor
soul's chaotic whoop, best described as a singular blend of yodel and kazoo.

Over time I became something of a CW pathologist, keenly aware of each
station's affliction, including my own. These variations were useful. You
could tell who you'd already worked. If you were a regular on the novice
bands, you'd even get to know fellow travelers by their frequencies, since
many, like me, were "rock-bound" -- slaves to a handful of crystals. VFOs
were starting to make an appearance in novice gear...but see "chirp," above.

Now, in 2021, the chirp is gone. 

CW signals still have many distinguishing traits, though. These include
speed, keying weight, the operator's affectations and favored prosigns, and
direction-specific propagation anomalies. 

Here's where we stretch the central metaphor to just about max. 

If randomly occurring CW signals on our bands are creatures of the wild,
then...are FT8 stations the occupants of an urban zoo? Don't get me wrong:
It's a pleasant place, with free tram rides, open 24 hours a day. The
diversity of species is unprecedented.

But imagine, on a given day, that you've sampled the zoo's exotic offerings,
memorized the brochure, bought the t-shirt, and partaken of the sumptuous
snack bar. What next?

Take a walk on the wild side. 

Yank the cord and jump off the tram at an unmarked stop. Hop the fence. Work
your way down the unpaved trail from the upper mesa to the open savannah,
then sit on the ten-foot wall and dangle your feet over the edge. 

Welcome to the ecosystem of beings who are free to roam. They may be
camouflaged, blending into the background. And if you listen carefully,
you'll hear a hundred variations on their timeless song...CQ.

Wayne

[Elecraft] K4 Kit and CE

[Doug Turnbull]

Dear OMs and YLs,

  Someone on this forum stated that if sold in kit form that the K4 did
not need CE approval for sale in the EU. I am not sure this is true but
hope so and of course then hope that the kit is coming out sooner rather
than later. I have a deposit down for the second group of shipments and
this would mean that I might actually see the K4 sooner.

 

  Once the K4D with superhet frontend is available, the new front end
will be ordered plus a second K4D.I already have homes for my two K3
radios.Probably will also want another KPA 1500.

 

   So any word on CE approval process, whether it is required for kits
sold into the EU and the availability of the kit version of the K4 is
anxiously awaited.

 

  As and aside it would be nice if the next version of the KPA 1500
could be run efficiently at 400W.Contest power is generally 1500 Watts
in EI but normal output power is limited to 400W. An Acom 2000A also in
the shack may be the amp to use when operating under normal conditions.
Having said this, the KPA is a beautiful amp and it is for that reason a
second one is considered.

 

 Yes perhaps this is greed but at 76 there are not that many more
sunspot cycles in store for me. I started like most of you with a
surplus RGB II (forerunner of the HQ120) bought from summer job and baby
siting.The first rig was an old borrowed TCS surplus radio before
building a two 6146 rig from a QST article.What a great hobby radio is.

Re: [Elecraft] Free shipping

[Doug Turnbull]

Dear OMs and YLs,
  May I say that I agree with Richard.Free shipping while nice is not 
my concern but it would be reassuring for Elecraft to keep the many of us with 
large deposits better notified as to progress and delays.As I am in the EU, 
my shipment date will be longer by months than those of you in W land.  We must 
have CE approval for shipment; this is essentially a EU wide check for safety 
purposes not too dissimilar to UL approval but perhaps more wide ranging.   How 
much longer CE approval will take we have never been told that I can remember.  
 My money stays with Elecraft.I am an Elecraft supporter and owner of many 
Elecraft products.When this K4 becomes available I may well order a second 
K4 plus second KPA 1500.   It would sure be nice though to get a monthly update.

  It would also be interesting to have a more detailed specification sheet 
though I suppose this is being left to other labs to produce.   Elecraft must 
though have these numbers.   Maybe the good people in California want to make a 
big bang when the K4 does ship by blowing competition away.  

   I am not about to ask for a refund of my deposit but I do pray that 
Elecraft is not another casualty of the Covid 19 virus. There is enough 
suffering and much more to come in commercial life.   There are good people in 
the mother ship.

My two cents.  We all wish the best for Elecraft.  It has been horrible for 
them and all of us living with this cloud.  Free shipping or whatever I don't 
really care at this point.  What I find fault with is the lack of 
communication.  How hard would it be to have a regular update on the progress 
of the K4 box and other products?  Even if there is no new news just say so. I 
am sorry but the communication has been far less than desirable. When I look at 
the Elecraft "stories" the last update on the K4 was May of 2020.  The last 
update on in the newsletter was July 2020 with virtually nothing on the K4.  
Please...as you can see from the emails...just tell us what is going on.  99.9% 
of us are very understanding.

Re: [Elecraft] "On Second Thought, I'll Take The Stairs

[Doug Turnbull]

Dear Friends,
  Nor are SSB, RTTY and PSK the same as CW but they all serve a purpose.
Any technology which allows one to work weaker signals with lower power is
going to make DXCC easier.Even using CW it is infinitely easier to work
DXCC on multiple bands these days than back in the fifties, well maybe I
will make an exception for the 1958 era.There are so many aids and
radios are better.This is a technological hobby and now the guy with the
apartment and balcony might actually work DXCC.   Viva engineering.

I agree fully with Victor; though the difference may be even simpler:  

Making a QSO using CW is a ham doing something with a radio.  Making a QSO
with FT8 is a radio doing something for a ham.

Neither is better or worse; but they are different.

For me, it's simple.

When I make a CW contact, even if its total content is "ENN TU", I am
connected to history, to Jack Phillips on the Titanic, to all of the
military traffic men and airborne radio operators of WWII, to the operators
on the merchant ships on the high seas and the Great Lakes, and to all the
hams of the past, even Mr. Marconi, the first ham.

I like hearing the propagation change with my own ears and struggling to
capture an ESP-level call. I like the feel of the key and the sound of the
code. I like the idea that there is another person like me at the other end
with his or her hand on a key.

I consider myself extremely lucky to have caught the bug at a young age and
developed the skill needed to make CW as transparent to me as my mother
tongue. I see how hard it is for those who begin to learn at middle age or
older. They shouldn't give up -- it's worth it.

Re: [Elecraft] K4???

Wayne and all,
  Thank you, thus we know why the specifications for the K4HD are not
available. Though one wonders about K4 and K4D specs. What might we
expect if ARRL or Sherwood Engineering were to run their tests.No harm
in asking though you may have reasons for staying mum.You may be sure
that my deposit stays with Elecraft.The success of the K4 and indeed
Elecraft is important to me.I dare say that if you were inclined and if
it were legal shares in Elecraft could be sold along with your radios.
Elecraft is a company many of us want to support because product, support
and attitude are just first class.

Mike,

K4HDs will take longer. We were working on a final piece of the HDR module
when the lockdown hit. It also uses additional parts affected by the supply
chain, including crystal filters, different ADCs, etc. 

Those who take delivery on a K4D can later upgrade to a K4HD at any time by
installing the modules in the field or by sending the rig to Watsonville.
Availability TBD.

Re: [Elecraft] K4???

[Doug Turnbull]

Friends,
 If you are unhappy Elecraft will refund your money.That said, I too 
would like more information and would think that merely having put a deposit 
down would mean you would get updates either on this forum or in the Elecraft 
Newsletter.
I would like to know how much additional delay is likely for those in the EU as 
we must wait for CE approval before Elecraft can export to us.This is 
something like UL approval in the States.It is not a trade barrier but a 
safety certification. It would be interesting to know once manufacturing 
starts how long Elecraft estimate the time for CE approval to be granted.Of 
course there may be delays in this process due to Covid 19. I am happy to 
leave my deposit with Elecraft but then it does not affect putting food on the 
table.   Again if you want you can get your money back but it would be really 
nice to hear more about plans, problems and improvements to firmware.It 
would also be good to be given  specifications ala Sherwood Engineering but 
done by Elecraft.   They must know what the K4 is achieving in its different 
configurations.Maybe this it tipping Elecraft's hand to the competition.
 We are all being cooped up and getting a bit anxious.  At least we have 
something to look forward to.

All of that is true, except that it doesn't take somebody like Wayne or Eric or 
any of their engineers to draft a weekly status report to those who have put 
down a deposit.  Anybody who speaks with them regularly could do it.  I haven't 
ordered a K4 and don't know if I ever will, but I'd be pretty upset to have put 
down that much money for ANY item with this little regular feedback on its 
shipping status since I can't think of a good excuse for it.  From what I've 
seen, just about every status email from Elecraft has talked about K4 feature 
issues instead of when it might actually be delivered ... so no, I don't think 
that's being very transparent.  A year is a very long time to have your money 
tied up, and along with that comes some measure of responsibility to account 
for it.

Re: [Elecraft] K-4 capabilities

[Doug Turnbull]

Hello Mike and friends,
  Well you are not in the EU and do not need to wait for CE approval.
The start of this process can only begin as I understand with a production
model.Until CE approval is obtained Elecraft can not shirt to the EU.
I am not complaining about EI being in the EU but am anxious.I suppose
one could bring one back from the USA on a plane and declare it in the
airport but there are no flights out of EI to USA for such purposes these
days.My radio is also paid for and ultimately it will be the K4HD.
One can add the "superhet ?" front end later when it becomes available.

PS this is what happens to one who is cocooned.   Over 70s in EI are not
even supposed to leave their property to go grocery shopping
;  this is something neighbours are expected to do.

Yes getting some more info would be great. I have been bugging the boys at
Elecraft for an electronic copy of the manual, but nothing yet. I have all
the cabling done and a spot cleared on the desk beside my
KPA1500 for either my K4D or K4HD, I too have paid the full amount and just
waiting for the early May date when California will ultimately decide if
people can go back to work or will have to stay isolated further. I think

In the meantime I guess we will have to wait and stare at pictures of the K4

Wayne,
In these times of lockdown some of us are buoyed up with the prospect of
the new K4. Well some of the fortunate who are waiting for early
delivery.It is a bit like waiting for Santa as a kid.   When a toy
catalogue came in the door I devoured it; well maybe these catalogues are a
thing of the past.   Nonetheless, anything you can tell us about this radio
just gives us something to look forward to.I see from the back of QST
that the Kenwood TS 890S has some pretty nice features and impressive
specifications.It will be most interesting to see how the K4 stacks up.
Will Porsche surpass Jaguar again and claim pole position? The K4 is a
big hope for the future.Tell us what you can, we need bedtime stories to
fall asleep dreaming over.

settings per band and have to remember to reset the RF as I go from 160 to
20, for example. Will these settings and AF gain, etc be recalled per band?

Re: [Elecraft] QRO - KPA500 Failure

[Doug Turnbull]

Thank you Andy,
Bob, if maximum power dissipation occurs at 50% max output power then the 
greatest amount of heat should be generated for the shack at half max output 
power.  Power dissipation is in the form of heat not RF.   The subject is 
interesting for a number of reasons perhaps most importantly to me is that of 
reliability.  I believe the chance of failure is reduced as one lowers 
dissipation while staying within all other component ratings.

Unless one is concerned about power consumption, the efficiency factor should 
be really of no concern.   Total heat output will always be greater at maximum 
output and less at lower power.  Nice for warming the shack on a Winter day.

Re: [Elecraft] QRO - KPA500 Failure

[Doug Turnbull]

Hello Andy,

 I do not have the numbers and also would like them. I understand
that efficiency decreases as one derates from the maximum of 1500W output.
It surprises me that the power dissipated would peak at half power output or
750 Watts.   This may be so.If so then almost certainly the Mean Time
Between Failures or MTBF is worsened. I am not in a position to
determine any of this but maybe some guidance from Elecraft itself would be
helpful for both KPA 500 and 1500.

Doug,

 

"I would like to know if running 2/3, 1/2 or even 1/4 maximum power output
increases reliability and MTBF."

 

I have no experience of amplifier design but I would expect reliability of
the finals to depend on temperature.   Finals temperature will depend on the
power dissipated in the finals (PA dissipation) and the effectiveness of the
cooling design. 

 

To understands finals dissipation one would need to produce one's own test
data or rely on the work of others.   My test data for the KPA500 shows PA
dissipation peaks at about half power output.  So far no one has disputed
the validity of my test data. 

 

It is my understanding that running an amplifier at reduced power only
reduces PA dissipation if the finals voltage is adjusted give a good load
match for that reduced power condition.  The KPA500 has no provision for
adjusting PA voltage for the reduced power case.   For reduced power the PA
voltage is actually higher than for full power because the high voltage
supply is not regulated.  

 

As I said, I have no experience in amplifier design and would appreciate
comments from those who do.   

 

73,

Andy, k3wyc

Re: [Elecraft] QRO - KPA500 Failure

[Doug Turnbull]

Andy,
Yes, you are right and this applies to both KPA 500 and KPA 1500.The
conditions for maximum efficiency are not necessarily those for minimum
dissipation or reduced stress.I would like to know if running 2/3, 1/2
or even 1/4 maximum power output increases reliability and MTBF.It would
be a considerable surprise to me if this were not the case and it would be
good to know the numbers.Improvement in MTBF can be several fold for
some devices for a reduction in voltage, current or power of as little as
10%.Good design practice normally means that this is part of the
engineering design process.   The proof of derating is looked for in design
reviews.   Too many hams run their amplifiers flat out for very little
benefit.   Signal cleanliness is still another issue; higher voltage but
lower power seems to help here.

 Using FT8 or WSPR on dead band (160M in daytime or 12M), I sometimes
run 20 Watts plus.   This can be stressful on the K3 especially for WSPR.
I crank the K3 down to a watt or so and drive the KPA 1500.Yes, my total
energy consumption is no doubt up but stress on either K3 or KPA is minimal.
This however is not my concern, I would like to know if running the KPA at
lower power increases reliability.   In EI we can run 1500 Watts for
contests  but outside of contests can only run 400W max.

Yes, very true.  Only a few have actually contributed test data.  All the

The K4 has sufficient internal horsepower to run advanced software

to run in the K4 environment, and they'll be vetting by our staff before
being made available as an in-box app. 

While there's no reason we couldn't run Skimmer, I can't say at this time

Re: [Elecraft] K4 YouTube Video List by Date

[Doug Turnbull]

Charles is correct.   Even the fully loaded K3 is more expensive than the
fully loaded K4.Look at all the add ons for the K3 such as high
stability oscillator and DVK then add in a full eight roofing filters when
you have a second receiver.   The P3 with external monitor card and before
long you are touching $6000 plus.  Remember the addition of the KB3 to allow
out of amateur bands reception.  Now take into consideration even the low
inflation of recent years and I am talking K3 not K3S.The K4 is not
harshly priced plus the performance is improved at least from the Graphical
User Interface point of view and probably from an RF perspective as well.
The total package is smaller than a K3 with P3 combination.Elecraft is
not gouging but presenting to us a new opportunity with what one hopes is
going to be again the top of the pile radio.   You can not expect to
purchase a K4D with superhet front ends for the price of an Icom 7300.

   The Icom is a great radio for the money but it is not in K4 territory.
You can gradually build up to the ultimate K4 if this is what you seek.
Again the modular approach taken by Elecraft is an advantage.   It also
seems that Elecraft is allowing for considerable expansion of K4
capabilities in future.

   Of course everyone is interested in seeing if Elecraft advances the
specifications as reported by Sherwood Engineering.   The user interface
will be improved now will the RF performance still be improved as well.   

   I suspect that in most cases an old Drake twins pair will work everything
the K4D will work on non WARC bands but it may not be as comfortable to do
so.   I enjoyed the Drake twins but would not go back.

   Put the fully loaded K4 up against the best of the competitors and look
at the prices.No I am not suggesting that our friends should not get
greedy but as things stand it looks like the K4 is a pretty fair deal for
one seeking the top of the line.

   May I also remind you that you are dealing in a radio made by people who
speak English.   The manuals tend to be better from our perspective.   I
have a Toyota Prius Plug In and boy does that manual have problems.
Technical writing is not a trivial matter.   This radio is going to be
complex.   We also have what from Elecraft what I believe is the best
support in the industry.   The Chief Engineers and CEOs Wayne and Eric
participate in this forum.

If you outfit a K3s with everything that is included for example, in a K4D,
I believe you'll find the K3s package is actually MORE expensive than the
K4D.
Don't forget to include:   The P3, + transmit monitor, +  VGA output option
(more modern HDMI on the K4 ).

[Elecraft] K4 rumors and Manual

[Doug Turnbull]

Dear OMs and YLs,
It is better to wait for a well written manual than one which needs
work.   Fred Cady had an advantage of a pre-existing manual and knowledge
gained on the forum over a period of time.  Elecraft does not have this
luxury.Also Fred did not need to cover everything that the Elecraft
manual covered but could elaborate in other areas.   Well Fred was a teacher
and writer so naturally he did a super job.   Elecraft did a good job as
well but it was good to have a second perspective.   I pray that I did not
step on the toes of the Elecraft technical writer who quite possibly is
Wayne or Eric.It is a small company doing a wonderful job.   Better the
manual be a bit late than lacking.I am really anxious to see how this
new radio performs.   Specifications are not given or available yet.   We
will need to look at Sherwood Engineering test spectrum to see the whole
story.Naturally, I am rooting for Elecraft.

 Happy Christmas and a Prosperous New Year to all,who work in Elecraft.

PS I suspect the changes in performance will be incremental.   You will
still work anything with a K3 that a K4 will work.  Probably the user
interface for the K4 will be improved and this may be quite significant to
many of us. 

PPS It is good to see the modular approach still being used.  You can start
in with a relatively modest expenditure and build up over time.It seems
to me that the real price of a fully loaded K4 is less than that of a fully
loaded K3.  This and the total box size is smaller.

Re: [Elecraft] K4: savable profiles?

[Doug Turnbull]

Dear OMs and YLs,
Even if this could be done in the K4 Utility it would be useful.   This
facility might even be better in the Utility if this helped to keep the
radio user friendly.   Boy, this list goes on and on but it is good just the
same.   We are all writing our letters to Santa.

Will the K4 have the ability to save (and then select from) various
"profiles" so that a user can go from, say, 20m 100-watt CW to 80m 10-watt
FT8 with all the saved settings (power, mode, bandwidth, audio in/out
levels) taking effect simply by selecting the chosen profile?

Re: [Elecraft] K4 RX routing?

[Doug Turnbull]

Dear OMs and YLs,
 Carl is absolutely right.  The K4 and its different variations is a
complex radio.   We need someone to write a "Lady Bird" users guide.Fred
Cady did a great job and is sorely missed.Now Elecraft has a new
challenge.   You produce good manuals but perhaps did not have the time to
do what Fred did and after all Fred was a retired EE professor - a great
teacher.   The manual is important!   You are writing in your native tongue
and hopefully will do a great job as you do every where else.

Further on this:

Please include a comprehensive description of RX antenna routing in the K4
manual. I could never understand the K3 with much confidence until I read
Fred Cady's KE7X (SK) book, and sadly Fred will not be writing a K4 book.
Just try figuring out what "RX Ant Out" does by reading the K3 manual. You
can GUESS what it does but a manual shouldn't leave you guessing.

At risk of starting a FIRE storm here in the group, why not CORRECTLY 
configure the ALC between the amp and radio.  Just remember it is not a 
power control application but no different than the normal ALC in your 
radio.  You do use that don't you? And you can see the amp ALC on the 
K3S display ALC indication.  It will let you know if you are punching it 
too hard.

Dear OMs and YLs,
 Why not just run 1400 Watts.The difference in power will never be
noticed by anyone you are working.It should reduce stress on the KPA1500
components.   Though feedback which is after all what we are talking about
can not only reduce distortion but in some instances introduce distortion;
ALC being just one example.   If your SWR forces the return power to over
200 Watts then it seems to me there is the more important problem to
address.

 I am sorry if I have stepped on any toes.   This is not my intent.I
too run a KPA 1500 which is a delight.

This might be fine for the USA market but might well be problematic and

does not matter but I doubt this.What is one man's improvement could be

Something I'd mentioned earlier that would 
be good for the K3 will also apply on the 
K4 as well: Operating permissions per 
band. Perhaps an option for license class 
operating permissions. Select to engage 
the option for General and you will always 
be 100% operating properly as a General. 
An Extra uses the radio, select Extra and 
forget it. 

For example, the band segments contain 
different frequencies in the US for 
different classes/modes of license. To 
have a user selectable option in config to 
prevent a General from Tx in an extra 
segment would be an asset. 
Likewise this would prevent an Extra from 
inadvertently operating a mode outside 
their permission.
Another reason if you allow a Technician 
operator to use your radio say at FD, they 
might be unused to your radio and this 
would prevent them from going outside 
their permissions.

To be able to select per band where you 
are allowed to transmit & the mode 
permissions would allow anyone in the 
world to configure their K4 properly to 
meet their country's band plan.

Hi David,

The K4's LCD has nearly 3x the area of the P3's, and 5x as many pixels. The
resolution (pixels per inch) is about 30% greater. It's faster as well as
brighter -- the K4 screen was easily readable in diffuse daylight during
Field Day, while some other rigs' displays were not.

The K4's panadapter area using the standard display format is 25% greater
than the P3's. This doesn't include the per-VFO "mini-pan" displays that
overlay the S-meters, when desired, for fine tuning of signals.

Thanks to the much larger LCD, variations on the panadapter could be created
that are much larger than this, at the expense of some per-receiver icons
and the S-meters. So far we haven't felt the need, partly because the K4
includes an HDMI output that can drive an external monitor of any required
size. This external monitor can be configured to display just the
panadapter, with independent settings from the panadapter on the LCD.

Beyond this the K4 display provides:

- dual-pan mode (separate panadapters for main/A and sub/B)

- single or dual text decode windows

- far more digital signal processing horsepower (in aggregate, 
  roughly an order of magnitude greater than the K3S+P3)

- built-in IQ data streaming for use with computer applications

- a configurable multi-band mode to allow a quick check of activity
  on your favorite bands
 
- more flexibility in terms of display functions

- overlays for various functions (e.g.: DX call station list, 
  help information on all controls, RX/TX graphic EQ, alphanumeric
  keyboard for message/macro/menu entry, etc.); 

- virtually unlimited code space for future expansion; examples
  might include high-performance data decoders, AZ/EL display,
  custom station controls, image display, etc.

In short, the K4's display is much larger and more versatile, providing the
kind of control visibility and convenience that's only possible by
integrating the display into the transceiver itself.

Oh, and it's really fun to use :)

Re: [Elecraft] KPA-1500 on digital modes

[Doug Turnbull]

Dear OMs and YLs,
 Remember that a small reduction in power, current or voltage for most
electronic components gives a manifold increase in reliability.   Not only
is it better for other users but I will bet the KPA1500 is a lot happier
(more reliable) for a 20% drop in output power which is memory serves me
right is about 1 dB drop in signal strength.

[Elecraft] K4 24 hour clock and calendar

[Doug Turnbull]

The K4 will display time and date; I have seen this on one image.   Is there
any chance that in the new design the 24 hour clock and date will hold their
accuracy over prolonged periods?   This was not the case for the K3 and
would be an improvement.

A friend just advised me of a new FCC Petition for Rule Making that 
requests the creation of a new amateur band for 8m somewhere between 40

https://ecfsapi.fcc.gov/file/105260090923685/8%20meter%20PRM.pdf

I doubt it gets any traction, but it makes me curious if any mods 
(software or hardware) would be practical to allow the K3 or K3s or K4 
to cover that range.  I suspect the upper low pass band filter would 
preclude that possibility.

[Elecraft] K4 Ergonomics etc

[Doug Turnbull]

Dear OMs and YLs,
  I had a chance to see the new K4 at Friedrichshafen.It was like
visiting flowers with bees swarming to have a go.I am impressed and have
a few points perhaps not mentioned previously.

 1) Ergonomics:

a) The Main tuning know is raised and has clustered directly around it
certain LEDS and Switches of particular use in tuning.

LEDS are TX, Delta Freq, SUB (RX), and DIV for diversity.Having "Delta
Freq" directly adjacent to the tuning know may help me remember to stay off
a DX frequency. 

Switches are Freq Ent, Scan, Lock A/B and Sub/Div.   Positioning these
switches right at the main tuning know seems to me an improvement over the
K3/S.

b) Having the Spectrum display directly in front and on the radio itself yet
also giving a good size for the spectrum display is also to my liking.

c) Because the spectrum display is built in, the radio is not as wide as a
K3 and P3 combination.The HDMI port still allows me to have a 24 inch
monitor for the frequency display so the slightly smaller display will not
cause me difficulties.

d) A built in P3 should reduce the number of external cables.

e) The tactile feel of the switches has been improved.

2) Economy, Many accessories of the past are built in.

a) No need for a DVK CW, voice recorder card as this function is built in.
b) No need for a more stable oscillator as this too is built in.
c) No need for a wide band filter to allow general coverage because if you
switch out the superhet front end, you already have a general coverage RX.
Eric confirmed that the Superhet front end can be bypassed.
d) No need for a 4 kHz filter for FT8 as you can just switch out the
superhet front end.FT8 is normally not a mode used in contesting so
should be pretty robust without the superhet front end.
e) No separate P3
f) No need for an accessory board in the K3 to enable an external monitor.

3) Ease of installing updates for diversity and also superhet front end; I
understand that it will no longer be necessary to unplug the front control
panel in order to install these options.This was always a bit of a
worrying moment for me though I have assembled three K3 radios and removed
the front panels on a number of occasions for updates such as installing the
DVK.   I am an old goat with shaky enough hands and deteriorating eyesight. 

 I should go through the specs to compare total weights of a fully equipped
K3 and P3 combination to the fully equipped K4.   This data is probably not
yet available.  How will the power consumptions compare?  It will be
interesting to see the full specifications and Sherwood test results.   No
matter, my plans are to purchase in the next twelve months.   I like the
Elecraft philosophy of keeping the radio relatively small, light and most
importantly allowing for future enhancement.

  Agreed you will work anything with the K3 that you can work with the K4.
Most likely the 7300 will work 99.9% of what the K3 works but a VW Beetle
will do what a Porsche does but just maybe not with the same style.

Re: [Elecraft] K4 Questions

Would switching out the superhet front end allow a wider bandwidth for FT8
in the event that narrower filters are used in the front end.

a)  Direct-sampling passband is flatter than the flattest crystal filter,
with no ripple or group delay issues. Better sound on SSB, ESSB, AM, and FM,
and possibly lower error rate in some digital modes, DV, etc.

b)  Direct sampling provides a wider bandwidth looking into the DSP,
allowing for some advanced noise reduction capabilities including new NR,
frequency-offset noise cancellation, etc. These features will be evolving
over time.

c)  Turning off the superhet module will allow RX/TX operation near and at
the IF (8.215 MHz). 

d)  Current drain will be lower with the HDR module turned off.

Maybe. Someday. But I can't say for certain. Another possibility is a
"K4/0", i.e. a K4 with only a front panel and host interface module, but in
the same size chassis as a K4. Any K4, including a K4/0 or -mini, will be
able to control another one.

No data on this yet. But you should be able to turn off the panadapter
stream if/when you don't need it. Good idea.

Like on most of our radios, the KAT4 ATU is optional and can be added at any
time. This allows those using the K4 full time via an external amp with ATU
and external antenna switching to lower their cost.  This also applies to
those who are dedicating a K4 as an IF radio for VHF/UHF/Microwave.


 > 2- how many USB ports on front panel?

The K4 has one USB-A on the front, two USB-A on the rear.  If more inputs
are 
needed, an external USB hub can be used on any of these.
Mouse, Keyboard, Flash Drive etc can be plugged into these ports.

The K4 also has  one USB-B on the rear (with internal sound card and mutiple

comm ports like the K3S).
>>> 3- how many SO-239 connectors on rear of K4?  Photo shows 4 but I wonder

All three K4 versions start with one SO-239 for Hf-6M.  Three total when the

KAT4 is added.
There is a 4th rear position for an antenna connector when a future planned 
VHF/UHF dual-band internal module is released later next year. That will 
accommodate a SO-239 or type N socket.

As long as we have not filled it up, we'll move you up to the 1st shipping

Re: [Elecraft] Fwd: K4 Questions

Hello Eric,
Just to be sure, I hope there are two separate RX antenna inputs for
diversity reception on the K4D.Is this true are the RX ANT connectors
type BNC?

Will one need to take the K4D completely apart if later a decision is
made to add the two superhet front ends?

Thank you for all the good product, excellent service and presence of

I regularly delete posts whose titles do not interest me and click to

Thankfully the forum does not require a pass word such as use to be the

 I was okay because it was shipped directly from the factory.This

You're welcome, Doug.  I'm glad you have the KPA1500 up and running.

 

Your note, and my recollection of installing my own KPA1500, identify an
important omission in the KPA1500 manual.  Some other shortcomings of the
manual (such as a decent working block diagram) are merely irritating but
not including the proper mains connection for a $5000  device shipped
internationally is a serious oversight.  It's clear there is not a
widespread appreciation of global power standards in this email group (for
example) and, rather than having a future user stumble across incorrect or
incomplete information, the Elecraft manual needs to have the definitive
instructions up-front.

 

I'm not sure how the EU regulations are constructed but I suspect that it's
technically illegal to use the supplied cable in Australia.  For Australian
users a more immediate consideration on opening the box is that the US cable
won't fit through a standard Australian mains plug cover.  You can buy one
Clipsal brand plug from a specialised electrical wholesaler which will work,
or you can use a heavy duty plug and socket if available.

Ken, Doug

Ken is correct.  Your amplifier comes with a US colour coded cable and, for
your 230V supply, black is active, white is neutral and green is earth.

I had some additional searching to find an Australian heavy duty plug that
would fit the supplied mains cable and a standard 240V outlet, but was in
the end successful.

Peter, VK6HP

Subject: [Elecraft] Quandary - Anyone Seriously Considering the
Alternativeto the K4?

Hi:

I plan to drop my use of Flex radios this year. Until yesterday, I had the
new FTdx-101 and a K3S in mind but I'm not in a big rush and was hoping the
rumors of a K4 would turn out to be true. Have to admit, I'm surprised by
how fast it was announced.

So I'm wondering what other people might be thinking about what seems to be
two or three great options (Ftdx, K3S, K4). We can do this by direct mail
if you like as I don't want to turn this into something it isn't meant to
be. I'm just looking for other hams that might be thinking on the same
options and maybe want to bounce some ideas around.

My goal is a purchase by March 2020 but by the end of the year if I can
pull it off. I'll have a 6500, 6700 and Maestro to offset the costs. I have
a KX3 I'll be keeping for days in the fresh air.

73,
Kev N4TT

[Elecraft] KPA1500 AC Mains wire colours

Dear OMs or YLs,
 I have a new KPA1500 for use in Europe.  Mine came from Elecraft direct
and thus has a US style mains plug and I assume US colour coded AC power

The manual does not supply a schematic and I do not want to open the amp at

Re: [Elecraft] Modularity

[Doug Turnbull]

Dear OMs and YLs,
 For me the K3 epitomizes modularity.   One can build the radio up over
time and purchase only those features required.   This keeps entry level
prices down and enhances repair.   From Ireland, one could return a faulty
module perhaps holding on to the K3/S and continuing to operate.I hope
Elecraft continues this approach.   Yes and keep the power supply separate.

 I find the P3 is pretty good especially with an external monitor.
Maybe the next display will be more like what Flex offers but for me
Elecraft beats Flex in most regards.   Oh, thanks Elecraft for the K-pod.

I agree with Victor's comments.  I am all in favor of the elimination of
the all-in-one, big box rigs.  No vendor in the amateur radio market can be
the premiere supplier in all areas even though Elecraft is trying hard. I
don't consider them the best panadapter HMI vendor or best paddle
manufacturer.  What I would consider ideal is a rig, computer, and other
"boxes" which sit behind or below the operating desk (or at a remote
site).  On the desk, a keyboard, mouse and/or trackball, an advanced KPod
with a few more knobs and customizable LCD keys for the major rig control
and antenna  functions and monitor(s) for the waterfall, frequency
readouts, SWR/POWER indicators, RF waveform display and logging displays.

An enclosure to corral all the miscellaneous "boxes" and their wiring would
also be nice.

The trick is to provide a full complement of "hard" controls for functions
accessed most frequently, "in the heat of battle," as they say, while
leveraging the touch screen for its versatility. 

Touchable fields can be added as a backup/shortcut to hard controls. A touch
screen inherently offers immediate context-sensitive feedback and in many
cases reduced time/effort. Examples include signal selection, zooming, etc.
Zooming should also be done right, by resampling at narrower resolution --
is shouldn't just be a "blow-up" of the original pixels, as implemented on
some existing radios.

Ultimately, get what you pay for. That said, current prices for "high-end"
super-radios are ridiculous; they're two to four times higher than
necessary. Not only that, they're not configurable or upgradeable. Very
un-Elecraft like.

Dear OMs,
It is also possible to print on one side of the page and keep the back

such an ongoing basis.

Don makes an excellent point regarding new firmware release notes.  Unlike
other manufacturers, Elecraft manuals in PDF allow us to make notes with
Acrobat Reader.  If pertinent, I update my manuals with release notes.  That
reinforces the changes, even if briefly.  However, when I look in the manual
for a specific function, I will likely see the note with the most current
information.

RTFM is a popular acronym today.  It also implies the "M" (manual) is
current.  It's our, IMHO, responsibiliy to keep our manuals current.  We can
even add our own notes, like lessons learned.  Once updated, I save mine by
adding "Annotated" to the original filename.  I also keep copies on any
computer I might use with the gear, especially ones I take on-the-road.

Re: [Elecraft] DX World Transceiver survey

[Doug Turnbull]

Dear OMs,
It is a bit like surveys the BBC occasionally runs.   If there is an
Irish element to it then the whole of Ireland gangs up and skews it to
praise an Irishman, song, poem or what have you.

Re: [Elecraft] Which Amp ?

[Doug Turnbull]

Dear OMs,
I have both Acom 2000A and SPE Expert 2K-FA amps.The advantage of
the SPE is that it is instant on, operates on six meters, has multiple
antenna inputs and does not generate as much heat in the shack.   Its
disadvantages are audible noise which for me is horrific and also I am
getting RF noise on six and ten meters which does not show up on the lower
bands.   Literally I see the S meter go up an S unit in noise when I push
the operate button.   The Acom 2000A is a valve amp and is quiet operating
without electrical noise.   It is more tolerant of higher SWR antennas such
as the SteppIR trombone on 30M - the SPE can generate hash on thirty meters
annoying other hams if I am not careful.   Generally, I prefer to use the
Acom 2000A but for HF DX I sometimes use the SPE Expert 2k just to avoid a
2.5 minute warm up.

 I am beginning to think that the new Elecraft KPA 1500 may be added to
the shack to replace the SPE amp.   I suspect the Elecraft amp is also quite
noisy compared to the Acom 2000A which uses valves.

The manual for the SPE 1.3K found on the Expert Linears website

It is possible that there is an internal attenuator that may be disabled
for amplifiers sold in countries that do not have a gain limit.

Thanks Jim, K9YC, for the detailed information.  I too concur that wide 
signals can more likely be the result of the waterfall adjustments, or 
the system gain, which has the no signal noise level above 30 dB on the 
WSJT-X bargraph indicator.  If this is the case, adjust the audio level 
in the Windows application to reduce the level.

As to AGC, I run AGC on my K3S on Fast when operating FT-8. Likewise for 
CW.   Thus I've found no disadvantage in having it on, and little to no 
advantage in having it off.   Other than I manually have to adjust RF gain.

On that note, for the most part on 160 M, 80 M & 40 M I do run 15 dB to 
10 dB of Attenuation and back the RF Gain down accordingly.  For higher 
frequencies,  60 M and above, I do not use Attenuation and adjust the RF 
gain accordingly.  This seems to produce optimum receiver performance. 
On 6 M I do engage the preamp.

Re: [Elecraft] K3S VS: IC-7300

[Doug Turnbull]

Friends,
There are some other points not mentioned.   Yes, I agree the K3 is
pricy but the performance is there.   However for most things the IC-7300
does a grand job as does the TD590s.For now and for some considerable
time in the past though the K3 has had a superior receiver good in contests
and with high power neighbours.

 Other K3/S advantages:
1)Modular construction allows one to only purchase what is relevant to your
needs and to build the radio up over time if desired.   This also
facilitates repair as modules can be swapped or sent back to California.
No need to send the entire radio.   Elecraft if you make a new radio in the
future try to maintain this modular approach.

2) Just what type of support does one get from Icom?   I very much doubt
there is an equal forum with the designers involved.Support from the
factory in getting questions answered is also excellent.

3)More attention should be given to the clean output signal of the K3.

4)I wonder if the facilitation of digimodes by the 7610 is the equal of the
K3/S.

5) There is a very full line of accessories for the Elecraft line and again
all of this is modular.

6) The ability to at least assemble the radio gives the owner of a kit built
radio a better understanding as to operation and trouble shooting if ever
needed.   It also saves on import duties into the EU.

  Maybe Wayne should toot Elecrafts horn for these advantages as well.
Again though you can work DX with an old FTDX 100 or Drake 2B with Johnson
Ranger at much lower cost it will not be so well facilitated.   The fully
equipped K3 is not an inexpensive radio it is a Porsche of the radio world.

   I can not imagine a company better than Elecraft to deal with though
I understand that Flex is pretty good and so to has TenTec been in the past.
Are they as good - this is hard for me to believe.

I didn't see any comparison chart for the K3S and the IC-7610.  I did 
see the comparison of the K3S with the IC-7300. This made me laugh. By 
the time you add up the required options for the K3S to achieve feature 
parity with the IC-7300 it costs 3 times as much. This actually makes 
the IC-7300 look like a really good deal. The IC-7300 is, after all, an 
entry level radio.

I'll never stop being impressed by the ability of the K3/K3S. But, to 
me, it is no longer cost competitive. The only advantage the K3S has 
today is it has one of the best receivers. I doubt this advantage will 
last much longer.

This is something I fight personally when I decide to enter a CW contest.
Technology is great, it has allowed those who are either not proficient at
CW or can't even copy CW, to be able to communicate.

I've always thought the focus of a "conTEST", whether CW or SSB was to test
the capabilities of the "operator" to accurately receive the information
sent, making as many contacts in the time period of the contest as possible.
Scores determined in part, by busted calls or other information copied
incorrectly, and then scoring against their peers. 


Today there are a lot of (Robots) that can decode CW. It is true that all
robots are not the same, and errors could occur. Just wonder when we draw
the line as to who/what is being judged for accuracy.  


I love the technology. It's great for communications. (I think you know
where I stand on robotic modes like FT8 :) )

But in a contest, "these days" it seems to come down to who has the best
robotics (machines) to eliminate the human element for the sake of driving
up the score to new levels.

Re: [Elecraft] KX3/KX2 Cruiseship Operation

[Doug Turnbull]

Dear OMs and YLs,
 This talk of cruise ship operation piqued my interest.Do you have
to get permission from the ships captain to operate?   I believe this is in
the license manual.How does one go about doing so?If I could bring
my AlexLoop and KX2 aboard a cruise ship this would give a great new reason
to talk to the good XYL about a Mediterranean cruise.I just wonder how
one gets the okay on a big cruise ship with thousands of passengers.   I
would be hesitant to even take a KX2 on board a large ship without prior
permission.

  Surely one does not need to leave the antenna out on the deck area
when not in use.The AlexLoop is so discrete that from your own balcony
it should be possible though you would have to keep the antenna clear of all
the metal surroundings so this might well be problematic.

Re: [Elecraft] Is K4 talk verboten?

[Doug Turnbull]

Dear Friends,
For what it is worth, I have come to like the small size and light
weight of the present K3/S.   The modular approach to features aids purchase
and I believe also helps in troubleshooting.   This is a radio made for
contesting, DXpeditions, rag chewing and all modes of operation.   It may be
best to stick with the winner and continue to improve.   If a newer K4 is
eventually called for may it be small and light retaining as many K3
features as possible.

 Oh, I do like the P3 with 19 inch VDU and the K-Pod so adding on extras
is just fine.   The K3 line is a radio one can start out small with and
build up to what ever you desire.   I use to like the big Orion II and can
see that the FT 1000 MP were impressive looking radios but the K3
outperforms both in the contest sphere where a radio is tested as no where
else.

 There are Cadillac drivers and Ferrari drivers both cars have their
place but I just wonder if both are best made by the same manufacturer.
Inventory shoots up and engineering talent is more thinly spread.

 Whatever it will be interesting to see what the mother ship does in
coming years.  Just please do not fade out like so many others.   You people
at Elecraft are phenomenal with design, manufacturing and service.

Perhaps it does not matter what we write because most likely Elecraft is
already working on it.

The advantages of K3 are high blocking and dynamic ranges together with
quiet synthesizer. Also lighweight and good ergonomics to those who got used
to current. 

Minuses are lots of connectors/cables and high price. 

Making all SDR would make the radio lose high blocking range. Making the
screen bigger would  either make the radio bigger or the number of knobs
smaller. 

Here are possibilities
- SDR configuration with 2nd RX but with provision for current RX with
single Xtal filter
- panadapter display with connection to external display
- built in PS

Hi all,

If you use a K-Pod, or K3 macros in general, you may have occasionally
noticed that a macro's name was flashed on VFO B but the macro itself didn't
get executed. This would only happen if you also had an external application
such as LP-Bridge or HRD polling the radio continuously. 

The K-Pod is affected because it uses K3 macros to define its switch
tap/hold behavior.

I found the source of the problem and will have a new field-test firmware
release by tomorrow. If you have time to test it, please email me directly.

Re: [Elecraft] Taking KX3 on Airlines -Any issues/hassles with TSA/etc there days - with Bio-Engg 12V 7Ah Lithium Battery as Carry On Luggage

[Doug Turnbull]

Dear OMs and YLs,
 I have travelled across Europe and from USA to Europe with a KX2 and
had no problems - no one commented except the TSA man in JFK seemed to have
been an SWL and commented on how small they were making radios these days.
Surprisingly they did not want me to turn the radio on though I did have it
out of the carryon and on display.   Go for it and do not worry.   

 Take the battery in the radio and remove them when you get to KH6 a
charge only takes two hours so there is no big deal in this; a big advantage
over my KX3.  I had a second batter stored in the LowPro carry case and this
caused no concern - I would have given them the battery if it was a problem.
Enjoy your trip.

I've brought my KX2 with internal battery numerous times within CONUS. not
sure if Hawaii is any different. Don't have batteries for my KX3, but I did

Hi Chris,

The CS60 LowePro case I have seems well made, but having owned a Rose's 
bag for my KX3 for years, I can wholeheartedly recommend them!  One 
thing about the LowePro case, it is obvious studying the internal layout 
it was not designed for holding ham gear.  For instance, the lid of it 
begs to have stuff stored in the little pockets...but then they bang 
against the face of the KX2.  When you order a case from Rose, you get 
to customize it any way you want, and she has made so many cases her 
recommendations are spot on as well.  And, her workmanship is superb...I 
have dragged that poor KX3 and case over hill and dale for years now and 
it has not yet popped a stitch or torn anywhere..amazing quality.

Just my $0.02 worth...

Cheers & 73,

Re: [Elecraft] Can Anyone recommended a great QRP Antenna and Antenna Pole for KX3

[Doug Turnbull]

Dear OMs and YLs,
 The problem with poles is that even at four feet they are cumbersome to
take on planes.They also are obtrusive when installed.   The AlexLoop or
magnetic loop antenna on the other hand does not even require a pole and is
unobtrusive.   It can be used inside a frame or brick building though is not
so good in a steel structure though if close to a big window might do some
good and certainly is happy on a balcony.  If you have a roof garden that is
nice for operating outside your room.  For travel the AlexLoop is very hard
to beat.

  Now if staying with my brother I look for my end fed dipole and run it
about twelve to fifteen feet above ground and yes it will outperform the
AlexLoop.   Still you will make QSOs and plenty of them with the AlexLoop
running 5 Watts and using CW.   I can not testify as to effectiveness with
SSB.

  If you want a short four foot long pole for the AlexLoop and this is
not necessary then use a broom stick possibly whittled down at one end.
You can also take some fibreglass tube cut it into three sixteen foot length
and use two wooden dowels to join the three sections.   The dowels are
whittled down for a nice snug fit.

   When operating from a hotel it is best to be unobtrusive. That is for
certain.   It is all good fun.

This looks like cool accessory that should clean up many a tangled web. We
actually had something on paper several years ago, but it didn't have as
much flexibility in wiring signals to RCA jacks, etc. 

The only thing I'd do differently is paint it black and put a logo on it. Or

Dave and Phil,
All of what you say rings true but there is little reason not to have a
discussion.   We can always hit the delete button.The KX2 is very small,
light weight with a big display designed for portable operation so of course
the specifications will suffer some.   I hope there is a reason to own the
K3 and or KX3.Let us know what the specifications are in a form where
comparison is easy - thank you Sherwood Engineering.

I received a load of interesting and solid replies regarding my query 
about the IC-7300. Many were quite technical and some were excellent 
from a daily use perspective. However, without a doubt, the 
non-technical advice regarding a backup rig was the best I received.

" . put the money in a savings account and add $50 to cover next 
day shipping for the off chance your rig dies." It was also suggested 
that a second rig is an expensive paperweight (because modern rigs are 
very reliable). "Paperweight" is applicable in my case, as I am only 
able to operate a single rig at a time - I do not do multi-QSO well.

Hence, I have decided on an envelope in the desk labeled "for K3S."   
Better to do that, than to keep a spare on the shelf gathering dust. 
Further, there is no steep learning curve going from a K3 to a K3S.

Thanks to all that replied - I learned a lot.

Re: [Elecraft] Tracking Elecraft Feature Requests

[Doug Turnbull]

Dear Ted and Co,
Years ago I requested a pod to control memory and VFO.   It did not
happen and I requested again but then assumed it a lost cause and looked at
the fine K3 in front of me and the service given and decided well maybe
there is a reason and that is that.  Other solutions came out but it was
still not really what I hoped for.  Then out of the blue Elecraft brings in
the K-Pod which is far better than anything ever expected.

 In time some of the many other requested features may be introduced but
it is an Elecraft decision whether either practical or worth while.   If you
have a better radio available purchase it.

 Meanwhile I am perhaps a bit cranky but if as a company I openly
solicit suggestions the idea that they would be recorded by a third party
who would dictate to my enterprise well maybe I would be thick and stop
bothering with a reflector.

For me the fact that Elecraft has done so much development on an
existing product and kept older versions of the product up to date is just
wonderful.Then quietly Elecraft goes off and develops the KX2 post KX3 -
oh I will never need one of those.   Then I saw the KX2 at Friedrichshafen
and fell in love all over again.Let us not be too critical and let us
appreciate the ability to talk to the design engineers who own and manage
Elecraft.

I agree fully with Don and Dave (messages below) and others who have made
similar points.  To me it's very simple:  We are customers, not
shareholders.

There are features I wish their products had, and I have had no hesitation
to mention them on this reflector.  Perhaps uniquely among producers of the
type, as I understand it Elecraft monitors these posts.  If an idea has
merit, acquires some me-toos, and would work within the financial and
technical framework of the company and its processes, I have confidence it
will be considered.  But I do not believe the company owes me even so much
as an acknowledgment.   No more than I owe them an explanation about why I
haven't yet bought a KX2.  Elecraft is a very good amateur radio equipment
maker.  I am a happy repeat customer.  So long as I like their gear and
their service, I'll keep buying it.  If it were a publicly listed company I
might very well buy stock in it.  But it isn't, and I haven't.

I agree with Kevin's "Why"
Tell me of another amateur radio manufacturer who maintains such a list.

  This is *not* open source programming.
If such a list exists for any other amateur radio manufacturer, they 
would come out with an "improved" new radio (Mark VI) version and if you

wanted the "upgrade" you would have to buy the new radio.

With Elecraft, you get those "upgrades" at no cost, just download the 
firmware. You knew (or should have known) the capabilities of the radio 
when you bought it - you did review the specializations and features 
before you purchased it, did you not?

I don't think we need to have visibility into the Elecraft engineering 
resources, and prioritization of requests for added functions.

Those at Elecraft *do* listen and often respond to such customer 
requests, but the prioritization of those requests must be on Elecraft's

terms for reasons of availability of engineering resources and the sales

benefit of those changes.

Bug reports will get a different response than those requests for 
changed operation.  If bug reports are proven valid and repeatable, they

will be attended to promptly.

Re: [Elecraft] Mouse-n-Click QSY

[Doug Turnbull]

Dear OMs and YLs,
 To me this is harsh indeed.   Who provides better service for the Ham
Radio community?   Do we think that we are the directors of Elecraft?For
a moment it sounded like the K-Pod was being criticised - well this is worth
a lot to me and I have one on each of my K3 radios.   Elecraft, I am still a
very happy camper when it comes to your product line, service and
accessibility.   Clearly it is hard to please us all and I imagine these
critical e-mails stimulate further design ideas.

 I am thankful not to be tied to a PC!!!  It will become obsolete.   Not
many such radios will make it into the Steam Radio Category still being used
after twenty let alone fifty years.  

 Well that is my 2 cents.It just surprises me to hear such virulence
directed towards an amazing group of engineers with a first class company.

Subject: Re: [Elecraft] Mouse-n-Click QSY

When I see Elecraft dodge a trivial firmware change like this year after
year, I can't help but wonder if they have ulterior motives.  Maybe Elecraft
plans to introduce a $250 wired remote control knob.  Maybe they hope
someday the knob will control the P3 / PX3.  Maybe they feel adding a few
lines of firmware to enable a $5 wireless mouse will impact the sales of
their $250 knob.  Maybe they're just busy.  When they don't respond to a
feature request, it leaves us guessing.

This brings me back to my previous thread.  We need a more structured
approach to tracking Elecraft feature requests (and bugs).  We need a record
of when Mouse-n-Click QSY was first proposed.  Elecraft can come back and
say, "The P3 / PX3 is out of firmware memory space."  Or, "The P3 / PX3
doesn't have the MIPS to sample IQ, process the 1024-point FFT, update the
displays (spectrum and waterfall), field remote-control commands, . AND
position a marker based on the delta-X field in a mouse HID descriptor". 
This disposition will be captured along with the feature request in a
central repository for everyone to see, now and forever.   In another month
or two when someone requests Mouse-n-Click QSY, we can simply refer them to
the (now closed) feature request.  Ideally, they'd search the feature / bug
list first.

Clearly, Elecraft isn't interested in maintaining / exposing a list of
features and defects raised by their user community.  I've received several
offers from members willing to host this list.  We should have something up
and running in a few weeks.

[Elecraft] KX2 paddle problem addressed

[Doug Turnbull]

Friends,
Elecraft got back to me and are going to take care of my paddle.   They
have made improvements.   For one thing a blue locktite which can be undone
is now being used for the center posts.   They have also improved the way
the finger pieces mate with the gap screws.

 So I am happy about these new developments.

Subject: [Elecraft] KX2 v KX3 for air travel and hotel operation

Dear OMs and YLs,

 

   This is just to relate my experience and observations after using my

KX2 sn 1000 in Tenerife for the past week.This operation was just a side

event while travelling with my XYL - just a bit of fun.Previously a KX3

was used for such operations but for me the KX2 has advantages:

 

1) KX2 is smaller and lighter.

 

2) The battery charge is much faster taking about an hour maybe two rather
than up to sixteen hours.

 

3) The battery can be kept outside the KX2.   I have a spare Li-Ion battery

from Elecraft.   One battery was in the radio in case airport security

wanted me to turn it on - they did not. A second spare battery was tucked
neatly into the

KX2's larger carry case.   Airport security did not question the second

battery.  

 

4) Some people have complained about vulnerable speaker wires when opening
the KX2 but for me the KX2 is less vulnerable to damage than the KX3

ribbon cable.  Taking the batteries in and out is easier with the

KX2 than the KX3.

 

 For twenty QSOs the battery was only recharged once this took one hour.
The power level was 5 Watts with the display light turned off.   The antenna
was an AlexLoop which I prefer to almost anything else for holiday style
portable operations when flying.It is a very unobtrusive antenna which
works far better than I ever expect.The Alexloop is light and packs into
a small case provided by the manufacturer.AlexLoop assembly is quick and
easy.   The AlexLoop was mounted on a broom handle and tied to the hotel
room balcony just placing the antenna above the wall by about a foot.One
imagines the wall to be reinforced concrete.   The QSOs were mostly around
Europe though one QSO was made with K1RM in Connecticut and the best DX was
with WA8RCN in Ohio.

 

 I just about never bother with the QRP frequencies for such operations.
CQs are not made but stronger signals are answered.   Often I wait till a
QSO finishes before seeing if there is an opportunity.Sometimes the
signals are too weak for more that a rubber stamp QSO but other times a rag
chew developes.   I prefer the rag chew.

 

 I am not sure how things would work on SSB as CW is my mode and has
great advantage over SSB when operating QRP into a one meter diameter
antenna.

 

  The KX3 is a better radio than the KX2 and for me the KX3 receiver
with roofing filter does a better job.   One losses 160M and 6M with the
KX2.  Though TB is my band this is just not going to work out from a hotel
room balcony.   It would be nice if the KX2 had a dimple on the tuning knob
but this is a small point.The KX2 is not a radio for the base station
but the KX3 can serve this roll admirably.   The KX2 is a travel radio with
a great display which does all I need.

 

  Now for my gripe.   The KX2 paddle is nice and small.   I find it
handy to have the paddle attached to the KX2 when operating portable and
especially if on a park bench.When adjusted this paddle works just fine.
It is not a Begali but the AlexLoop is not a Yagi.   The trouble is that my
KX2 paddle kept going out of adjustment sometimes with a short between two
contacts and at other times with one of the two center posts coming loose.
I am not a paddle slapper and normally operate with a close spacing and
light touch.The KX2 paddle caused me repeated problems.   I have written
the mother ship about this and will see if my paddle can be serviced.
Earlier this month, I did note someone else having similar problems.
Perhaps the Begali Adventurer paddle with KX2/KX3 mounting bracket is a
better if more expensive option.   It is also at least twice as large but
would fit easily in the KX2 carry case.  I am just not sure if my Begali
bracket has the same problem that the original KX3 paddle bracket had with
the KX2.

 

  So this is my story.   The KX2 is a lot of fun for CW QRP operations.
My KX3 will be kept but will not travel so much.   If you are flying and
need an unobtrusive antenna consider the AlexLoop.   This antenna has done
some amazing things for me in contests with a KX3.

Re: [Elecraft] (OT redoux) MAG LOOP ANTENNAS

[Doug Turnbull]

Fred,
Well put and useful.I can though testify that the AlexLoop can work
amazingly well from inside a frame house and even a stone house as I have
tried this.   It also works wonderfully from a hotel balcony; though I
understand these are less common in W land for unfortunate reasons.   Keep
the magnetic loop off furniture with metal springs inside.

   The AlexLoop or Magnetic Loop is my antenna of choice for travel as it is
so unobtrusive and yet amazingly can work.This sounds like snake oil so
perhaps I am over enthusiastic.  I have used the AlexLoop in a part time
effort for a WPX contest.   Operation was from Connecticut with the antenna
inside my sisters house using KC1AV as my call.   I worked 270 some Qs with
a good 30% of these being with Europe.My power was 5 or 10 Watts -
memory fails me on this point.

 I have at times found the AlexLoop out perform a Buddipole at full 1/4
wave length for twenty meters with two radials.   How this could be well I
can not answer.   I am suspicious.At night it is surely easier to retune
the antenna when changing bands than having to go outside and change the
length of the antenna and its radials.  The AlexLoop capacitor is within
arm's reach.

 When possible for portable operation though I prefer an end fed dipole
but this only works when staying with understanding friends or family.

Subject: Re: [Elecraft] (OT redoux) MAG LOOP ANTENNAS

I'm not sure about a mag loop inside a room, I've never tried mine that 
way.  When used vertically outside, they tend to be insensitive to 
surroundings [trees, ground, you sitting under it] because the 
permeability of most such surroundings is 1.  This may not be true if 
you're set up on the track of a railroad yard ... or if there's a lot of 
ferromagnetic material in your walls.

If you try it, be aware of several things:

1.  Small magnetic loops involve some very high voltages and circulating 
currents, even at surprisingly low powers.  AA5TB has an on-line 
calculator and there is a similar one at 
http://www.66pacific.com/calculators/small_tx_loop_calc.aspx

2.  The equivalent radiation resistance of small loops is 
extraordinarily low -- in the milliohms range.  Your power will be split 
between the radiation resistance and the RF resistance of the 
conductors, which is higher than the DC resistance because of the skin 
effect.  You really need to achieve the lowest possible RF resistance 
[high conductor surface area].

3.  Mag loops are resonant transformers or autotransformers.  To radiate 
at all, they MUST be exactly resonant at your TX frequency.  "Getting 
close and letting the ATU match it" will create a fairly effective dummy 
load.  Bypass the ATU and tune the loop for exact resonance.

4.  The usable bandwidth will be very low [i.e. you need to re-resonate 
the loop when you QSY, even a little].  As the circumference of the loop 
becomes smaller in relation to the wavelength [i.e. on lower frequencies 
for a fixed size loop], the BW can become smaller than the occupied BW 
of a SSB signal.

Commercial mag loops [e.g. my Alexloop] are usable from 40 up. Tuning it 
on 40 is really touchy.  It's easier on 20 and up.  They tend to run in 
the $400 range.  You can build one much cheaper, but remember #2 above.

Fred,
I agree with all you say but still when reading a signal in the noise on
160M believe me a dB can help in recognizing a call sign.   I often think
that operating on TB is some what like operating on VHF/UHF.  It is
certainly a struggle with noise.

I have always been under the impression the doubling of output power will
result in a power gain of 3 db. And, that 3 db gain is the least signal
increase noticeable at the receiving point. KPA500 outputs 500 Watts - 1000
Watts would give an output gain of 3 db (over the KPA500) and 1500 Watts a
little over 4 db gain. That being my understanding - why would I want to
spend a box full of dollars for more power than my
KPA500 provides? Or, is my understanding flawed?

FWIW, I have run all kinds of amps in my nearly 60 years of being the on the
air and have found that Watts are Watts, regardless of how you generate them
(fancy, cheap, junk, or solid gold).

Everyone have a super HAPPY NEW YEAR!!!

"backordered" just after she place her order.

She received a call from Elecraft Customer Support pointing out we had both

Where else could you find such great customer support along with such fine

You can put away the tin foil!  The lines of force arriving thousands of

That's the difference between near and far fields.

On the other hand, that thought may make the tin foil more desirable!

Re: [Elecraft] Performance of the KX2 batt

[Doug Turnbull]

Dear OMs and YLs,
 I am not taking issue with what Howard is saying.   My operations are
different!The reason for entering this discussion is that the battery is
being mentioned which I am more than pleased with for CW at 5 Watts.  I have
some observations and a question to finish with.

 First the battery pack appears to weigh approximately half that of the
KX3 battery pack and is physically half size.I am most pleased at the
rapid charging time of about three hours versus up to sixteen hours for the
KX3 battery pack. From now on I will take the charger with me on trips - it
works from a wide range of line voltages. Different computer line power
cords for the UK, Europe and USA are easily obtained.  One battery pack
should do.   You can not run the KX2 from the Charger!!!   The charger is
light and small with the line cord being an unfortunate necessity.  

 Owning both a KX3 and KX2 my intent is in future to only use the KX2
battery pack with either radio.   Travelling by plane with KX3 may be a
problem in that the battery pack should be inside the radio.   The KX3 will
not be flying besides the KX2 is half the volume and weight.   Normally the
battery pack is kept external to the radio.

 Now this is not a comparison of like loads but I find that the KX2
battery pack will last nearly two pages of CW QSOs.  The life span of
batteries with the KX2 beats the life span of batteries with KX3 - this is
not a numerical judgement but one observed through operation.

 Does anyone in the UK or the greater EU have a source of the KX2 type
battery pack in Europe other than those sold by a UK official supplier?   I
want to continue using the KX2 charger.   Adding a connector is no problem.

Another KX2 KX3 topic:

 I find the KX2 an amazing wee radio.   My KX1 has gone to a new home
where it will be used on the trail.   I miss 160M and would probably like 6M
but to be honest TB is not used while travelling and the magic band QSO
style I find boring in Europe - no one rag chews.

 Hopefully Bob Sherwood will do a review of receiver performance.   The
KX2 can not(?) match the KX3 but it is everything I require for portable
operations.   Maybe the KX2 underperforms the KX3 for QRP contesting or for
a DXpedition with large pileups.   It would be nice to know the RX figures.

It was love at first sight when the KX2 viewed at Friedrichshafen.
This is a fun radio for someone interested in portable and especially tail
work.   Alas it is portable operations here.

Subject: [Elecraft] Performance of the KX2 batt

I have been running my KX2 with the Elecraft supplied batt pack for the
past two weeks and have a question for others using the same. I can run the
KX2 at 10W only till I have used 1.12 AH of the batt capacity and its key
up V=11.0 and key down is 10.3. At this time I can only run the KX2 at 5W.

I was expecting that I would be able to run the KX2 at 10W for a longer
period. I have repeated this through 4 recharge cycles and the results ar
the same. Is my batt pack showing reduced performance?

Overall I am very pleased with the performance of the KX2

Re: [Elecraft] {OT} Alexloop Walkham Antenna

[Doug Turnbull]

Dear OMs and YLs,
 When using the AlexLoop one always at a minimum starts out with the
antenna tuner bypassed and normally you leave it that way.   I have had
occasion to use the AlexLoop mounted atop a steel reinforced concrete wall
and found that the minimum SWR was not good enough so I used the KX3 tuner.
The location was very good and I still made some good QSOs.   Without doubt
I should have moved but the location was convenient as I had use of a part
bench looking out over the considerable height of Monticatini Alto in
Tuscany ( Italians please forgive my spelling).

 With the AlexLoop or any magloop close by you can tune it and the
narrow band properties are not a big deal.   It certainly is easier to shift
form 20M to 40M with an AlexLoop than with a portable vertical type antenna.

Subject: [Elecraft] {OT} Alexloop Walkham Antenna

Hi Stan
I own an AlexLoop  and a few of us hams went into a park and did some
 signal comparisons on  20 meters.   We compared an
Alexloop,  a full size vertical with four radials, and a 1/2 wave  end fed
for 20 meters.
I used an a/b switch on receive and transmit.
The vertical beat out the other antennas by less than an  an s unit.   The
Alexloop was almost as good as the full size vertical.  The only drawbacks
I see with this antenna is that it needs to be in the clear.   It also has
a very narrow bandwidth maybe  30Khz.
On a SOTA activation  making phone contacts on 20 meters was quite doable
with 10 watts last year.   You will need an SWR meter with a needle to
catch the quick dips as you tune the loop.

 bye Richard

Re: [Elecraft] {OT} Alexloop Walkham Antenna

[Doug Turnbull]

Hello Stan,
 If you go to the AlexLoop site and open clippings then go to Echo
Ireland, you will find a fairly lengthy review I wrote.I have not used
the AlexLoop very often with my KX1 and hence 2.5W but have used it
frequently with the KX3 at 5 Watts for portable operations.The antenna
works even when inside a non-metallic building.   It seems like snake oil
but it works.   I made the QSOs mentioned in the article with 5 Watts so it
would be harder at 2 Watts as you will be down 3 dB.   A dipole is going to
work better at any reasonable height but it will be for one band and takes
up a lot of space.   You can place the AlexLoop on a balcony, take it to the
park or better yet a summit and it will work.   I think it pricy but so too
are all commercial antennas.

 You could do a lot worse.   I am purchasing a KX2 to replace a KX3 used
in EI for portable operations in Europe.   I reckon the KX2 in its special
travel case will fit inside the AlexLoop bag.   Though I prefer using my
Begali Adventurer Paddle; the new KX2 paddle will be purchased as it is so
small and hopefully beats the original KX3 paddle.  Elecraft has come a long
way since the KX1 paddle.   You go trekking but I am an old goat at 72 and
do not want to carry anything more than absolutely required when using air
travel.

One big disadvantage of the KX2 is the size of the battery charger.   I
do not want to haul this monster around.   Maybe two battery packs will do
me but airlines do not like LiPo battery packs of any type outside the
radio.   I may just gamble of a second battery pack.   This however is off
topic.

 For me the AlexLoop works better than I would ever expect and even
outperformed a Buddipole using a full quarter length shock cord whip on 20M
with two raised radials.   This should not be the case but was for me when I
tried this comparison.Another advantage of the AlexLoop is that you can
change bands so easily.   At night time no one wants to run outdoors and
reconfigure a Buddipole - all I do is retune the AlexLoop which is sitting
inside the room  with me at arms length.   The AlexLoop is a useful antenna
for portable operations.   It is well packaged and easily assembled.  

 Good luck my friend.   These are just my experiences.   Again I suggest
you read the clipping of my review in Echo Ireland.

Subject: [Elecraft] {OT} Alexloop Walkham Antenna

I would like to correspond with anyone who has experience using the 
Alexloop antenna with 1-2 watts.

Normally, I use either an end fed antenna and a T1, a resonant linked 
dipole, or a resonant Par HF Omni-Angle (for 20 and 17 meters).  They 
all work quite well for their intended use but require some effort to 
erect.


I have been reading about the Alexloop Walkham for at least the last two 
years.  It would present some distinct advantages to me and the reviews 
seem to be overwhelmingly positive.


My concern is that while I have a KX2 for my home station, I only take 
my LNR five band Mountain Topper out on my portable jaunts.  On a 9 volt 
transistor battery, I get a bit over 1 watt; on 12 volts I get 2.5 
watts.


My specific interest is in finding out as much as I can about how this 
small Alexloop performs at such low power levels since its efficiency is 
reported to be about 7% on 40 meters, rising to about 25% on 20 meters.


An email to Alex has gone unanswered for the last two days.


Thanks and 73 from Stan WB2LQF

[Elecraft] KPod arrives in EI within 4 days

[Doug Turnbull]

Dear OMs and YLs,
 Oh happy days.   My K-Pod arrived this morning not bad for a trip
across the USA and Atlantic in four days.I was blessed in that no VAT
(23% plus additional costs) was taken this time.   Life is good, thank you
Elecraft.   I have desired this Pod since first purchasing a K3 many years
ago.   After a while acceptance that there was never going to be a Pod sank
in and then this year Elecraft came through.

 There are other solutions but this is neat and small.The memories
for CW and Voice can now be easily accessed without the finger hovering over
M1 or M2.   This was a pretty uncomfortable position.   It will even be
possible to kick back in the easy chair and tune the radio.   You guys are
good.

Re: [Elecraft] K3 mod for K-Pod level of difficulty

Hello Gary,
I am waiting for my pod to use with a K3.   Age means that sometimes my
hands tremble a bit - life is still good.   My plan is to get a forty year
old youngster to do the soldering if it looks at all questionable to me.
This is a shame as before becoming an EE I was a technician and as a
youngster built my transmitters from scratch.   Well the grass still looks
green to me.It is going to be a delight to finally have the Pod as I
missed it since changing to the K3 from Orion II seven years or so ago.

The job should not take but a few minutes so it should be possible for
you to find a friend in W1 land to do the necessary for you.   We help each
other in this hobby.

Enjoy your radio.

Re: [Elecraft] KX1 vs KX2 vs KX3? from someone who owns one of each..

[Doug Turnbull]

Don,
Thank you for this as it is most informative.   Have you any rough idea
as to battery life comparison for KX2 and KX3 - I realize this is a
difficult question.   Thank you once again.

Subject: KX1 vs KX2 vs KX3? from someone who owns one of each..

In addition to a few K3s, I also own a KX1, KX2, and KX3 and believe that I
am in a position where I can make a few unbiased comparisons between the
“KX” group.  EI2CN asked today about weight comparisons between the three
radios so I thought I would provide that info and add just a couple of my
own thoughts about the three different radios.

My KX1 (4 band and tuner) with paddle and 6 lithium batteries weighs 14.6
oz.

My KX2 (tuner and clock) with battery pack but without paddle weighs 20 oz.
The battery pack alone weighs 5 ½ oz.  Adding the KXPD3 (since the KXPD2 is
still back ordered) adds about  1 oz to make the total package 21 oz.

My KX3 (with all options and also with the 3rd party sidekick panels) and
with 8 NIMH batteries, charger and KXPD3 weighs 35 oz.…. The NIMH
batteries make up about 8 oz of that total.

Since I own and have used all three radios, and really have no reason for
bias, I thought I would share my thoughts relative to comparisons.  For
clarification these are MY opinions only … the way I feel about the three
radios as an owner of each… and of course this is not an attempt to be any
kind of in depth review or comparison…. I’m going to focus on the main
encoder dial only.

Here goes:

To me, the KX2 has rendered the KX1 obsolete  the KX2 has virtually
every capability of the KX1 but also has much much more … is about the same
size and weighs just 7 oz more.  It’s the perfect radio for travelling light
or backpacking for portable QRP operation.

I prefer the KX3 over the KX2   mainly because of the main tuning knob
…. It was apparently necessary to use a smaller encoder on the KX2 to keep
the overall package small (and that has been accomplished).  But to me it
came at a significant price because it is really rather cumbersome to slowly
tune the bands with the KX2 main dial when compared to doing so with the
very nice encoder on the KX3.  To me the main dial on the KX2 has the same
feel as the dial on the KX1 ….. while the main dial on the KX3 is more like
that on the K3 ……  the KX3 wins on my scorecard on that comparison hands
down, and it therefore remains my choice for most operating situations. 

There are workaround alternatives to make tuning easier on the KX2  .. for
example it’s actually easier to tune up and down the bands using the MH3
up/down buttons than doing so with the main tuning knob …. But who really
wants to tune a radio with mic buttons?  …. Not me!   Coarse tuning with the
VFO B knob is the best option in my hands… and I have mine set for 0.5 khz
on CW and 2.5 khz on SSB, which allows me to scan the band with coarse
tuning and tweak with the main dial when I find a signal of interest.

I will choose the KX3 for “in shack” use (but after the K3 of course) and
for any portable use when I want to spend significant time with the radio
and log lots of QSOs.   ( FYI, our Field Day group operated 1A here in Utah
using my KX3/KXPA100 at 100 watts , deep cycle battery, CrankIR and center
fed zepp … and, with lots of off time and sleeping through the night we
still managed to log over 600 CW qsos).   I will pick the KX2 for portable
QRP operation when I want to travel light and do not plan to spend hours on
the air.  I doubt that I will be using the KX1 in the future …. but it’s
still a keeper as far as I’m concerned ?

Just one man’s opinions …

73,
Don, N5LZ

[Elecraft] [KX2 KX3] KX2 v KX3 battery characteristics

[Doug Turnbull]

Dear OMs and YLs,
 I have a couple of questions regarding the batteries used for KX2 and
KX3.

1) What are the relative radio weights with batteries installed?

2)With standard NiMh 2600 ma-hr batteries in the KX3 and the LiPo battery in
the KX2 both radios running at 5 Watts on CW with lets say a 80% listening
to transmit time; what are the approximate battery life expectations between
charges for new batteries?

3) Can the KX2 LiPo battery be used with the KX3?

  I saw the KX2 and its nifty case at Friedrichshafen and am afraid the
KX1 has to go.   This will leave me with a KX2 and KX3 and I rather expect
the KX2 will be my main portable radio.   Even in its carry case, I can
place the KX2 inside the AlexLoop travel bag.

 My friend Hugh, EI9KF has just received his KX2 and marvels at so much
radio in so small a package.

 A final supplementary question is there no need for a roofing filter in
the KX2 or is it already built in.A bit of discussion regarding the
difference in architecture of the two radios would be interesting.

 Enjoy your radios.

 73 Doug EI2CN

Has anyone had much success using either an Alex Loop or Chameleon P Loop
antenna with their KX3? I have few antenna options in an apartment situation
and throwing a 25 foot long wire into a nearby tree has not worked for me.
Even tried loading up a 33 foot long aluminum balcony railing with no luck.

Thanks,

Re: [Elecraft] CrankIR or AlexLoop

[Doug Turnbull]

Hi OMs and YLs,
I find this discussion of interest and the positive points about the
CrankIR seem correct in all respects.   I use an AlexLoop for travels as it
is small you can install it on a hotel balcony, park bench in front of a
hotel window, inside a timber frame, concrete block or stone house and the
AlexLoop will work.   The antenna is only one meter in diameter.   As I use
a KX3 with this antenna the power limit is not a problem.  As I operate with
the antenna adjacent or very close by, the adjustment for frequency change
is no hardship - it takes but a few seconds.   So changing bands with the
AlexLoop is faster.

 No antenna tuner is needed with the AlexLoop and if you have one it
should be disabled.

 I am certain the CrankIR is a more efficient antenna but it is not as
compact and can not be used indoors.  Just about anywhere I go the AlexLoop
can be used without upsetting people or embarrassment.  I have worked across
the Atlantic multiple times with the AlexLoop indoors and have done this
from both sides of the ocean.

  So there are tradeoffs and thankfully we have choices.   The CrankIR
will outperform the AlexLoop every time but you can easily use the AlexLoop
and it does work.

I have the AlexLoop and just ordered the CrankIR. The AlexLoop can only do
20 watts because of the small variable capacitor. The CrankIR does 1KW and
has a much wider bandwidth after tuning. You shouldn't need to fiddle with
it after you change bands like you would with the AlexLoop for small QSY's.

Re: [Elecraft] Sherwood's receiver performance table updated

[Doug Turnbull]

Dear OMs and YLs,
 I think Bob says it well.  How can you compare a fine radio like the
7300 with a loaded K3.   They are not the same yet the 7300 will probably
work most of the DX that the K3 will for less money.A Cadillac is no
more functional than a Chevy.   They both go from A to B.   Okay, I would
prefer a Porsche but it does the same thing but in a more stylish and
exciting manner.   Your pocketbook decides.

  A good few hams have both Flex and Elecraft radios - we are fortunate
to see these newer USA companies providing such good products.   For now I
am an Elecraft man and suspect this will be the case till the pine box but
different strokes for different folks.A TS930 will still do a good job
on HF CW.   Let us not seriously compare an entry level radio with the K3
and at the same time do not let the previous KX3 and K3 Sherwood ratings
lead one to believe that the KX3 is a better radio than the K3.   One needs
to consider the whole package and yes Elecraft provides the magic of
allowing access to the principle design engineers.   I sure do like this
company.

Subject: Re: [Elecraft] Sherwood's receiver performance table updated

I think Chris has hit it on the head.  Looking at a high-performance direct
sampling rig vs. a high-performance superhet with digital features is
looking at "definitely different animals".  Exactly the same sort of
problem that comes from a question that begins "if you could have only
one...".

I love my K3, but own a Flex 1500 as well (dipped my toe in to test the
water).  I could happily live with only the K3.  However, I haven't jumped
into the different world of the Flex 6700.  I suspect if I did, I wouldn't
want to part with either of them.  They are different tools -- each excels
in certain situations.

The key thing that strikes me as a real advantage of Elecraft is how well
an old K3 performs when upgraded. You can't do that to a Flex
1500/3000/5000.  Elecraft is the only company that consistently looks after
their customer base by providing continuous improvements.
