Yes, look under the prices/ordering pull down arrow.

Subject: [Elecraft] K4 Final Retail Pricing
Message-ID: <CAGe0YDbfvMqsNk3Dk4h8bku=_uRAOhNDzJMeTmmppW5koh5Yug@mail.gmail.com>

We've just posted our final retail pricing for the K4 to the Elecraft web
page.

We worked hard to keep costs under control and the final price adjustments
reasonable with a retail increase of just $100 for the K4/10 and K4/10
versus their prior max deposits, and an increase of $300 for the K4D.

K4 Retail Prices:
K4/10  $3,599.95
K4:      $4,099.95
K4D:   $4,999.95
K4HD  ($ still TBD after final release)

The K4 general info and order page has also been updated at:
https://elecraft.com/products/k4-transceiver

When I placed my order In group one, I was told I could add the ATU when my order came up for ship.  What I failed to ask is if adding the ATU at the time of ship will affect my place in line when I confirm my order and pay the difference. 

Does anyone have any insight on that?

Based on the naming convention up to now I would say it is a factory
assembled K4 with 10W... a QRP K4 ;-)

Or it is a typo

Those prices look OK to me, it depends what happens when the EU dealers add their mark-up/import duty.

What I REALLY want to see is the TX IMD for the 10W and 100W versions at 10/30/50 and 100% PEP.  Please publish this as soon as possible.

My K3S is a great source of disappointment in this respect, especially when I look at the superb TX quality from the transverter socket. I really hope that the guys have paid more attention to this.

I only operate on 50MHz and above and it may well be that the 10W version with a driver amp would be better.  If the TX IMD is good enough, I will buy a K4HD. I need the blocking performance for EU VHF contests.

Subject: [Elecraft] K3 Line Out audio input to Remote Rig RRC 1258 MKII
Message-ID: <1601574780959-0.post@n2.nabble.com>

I have a Remote K3 using K3 Mini at my home shack.  The audio output  from
the remote K3 is taken from the SPKRS jack and fed to the Audio IN jack on
the RR box.  I have often wondered about taking audio from the LINE OUT jack
and feed that audio to the RR Box. 

Doing this would allow me to use the radio when I am at the remote site
without having to reach behind the radio in the rack and UNPLUG the audio
cable so I can hear the speaker.  Several times I have left the site with
out plugging the audio cable back in which renders the remote useless when I
arrive home.

I know the level of the LINE OUT is variable in the CONFIG menu.  Does the
AF control on the K3 Mini also  control the level of the audio to the Mini
speakers --- that audio would be fed to the remote RR box  from the LINE OUT
jack on the remote K3.?

I?m also using the K3/0-mini with Remote Rig. I have a splitter installed on the speaker output port where one connection goes to powered speakers in the shack and the other connection goes to Remote Rig.  Nothing to unplug and then forgetting to reconnect and the external speakers provide better fidelity than the K3?s internal speaker.

Keep in mind that the K3/Mini-0 controls what is happening at the K3.  So the question is what happens at the shack using the speaker volume knob there.  When changing the speaker volume at the K3/0-mini you?re also changing the volume of whatever is happening at the shack?s speaker output.  Thus, in my case, if the powered speakers at the shack are left on and I change the volume level on the K3/0-mini, it is also changing the volume level going to the powered speakers in the shack.  

IF LINE OUT is a variable in the CONFIG menu, whatever you change on the K3/0-Mini when in Config mode for Line Out will control the Line Level going out at the K3.  As I understand it, setting LIN OUT includes both volume level and the control of volume.  Tapping ?1? will change LIN Out to = PHOnES, and the audio level is controlled by the AF/SUB gain controls.  In addition, you would need to set SPKR + PH to yES so that audio is still provided to the Speaker when Phones is in use.  That way, you don?t have to change the audio output at the K3 when using it either by the K3/0-Mini or directly in the shack.  However, this also means that when you?re at the remote site, the K3 Speaker will be active when operating remotely.


Presumably you could connect your RR Box to this connection instead of speakers and this may indeed provide what you?re looking for.   What you?ll need to determine is whether the provided audio Line Level output will be sufficient to drive the K3/0-Mini internal speaker.   I don?t know if the Remote Rig audio will compensate for different levels provided by the the K3 speaker jack versus the K3 Line Out jack.

It seems to me that the simplest solution to your concerns is simply insert a splitter in the K3 speaker out jack and share the audio with external speakers at the shack along with the Remote Rig box.  With the arrangement, there is nothing to plug/unplug when you?re back in the ham shack and the process for speaker audio level control remains unchanged.

Assuming they have one to drop into your K4 it should not affect your ship date.

Subject: [Elecraft] Mod: Improving Temperature Stability of K2
Message-ID: <40F7D8D7-070B-4E1F-A027-39CD1D55A571@me.com>

Hello K2 enthusiasts.

I?m installing the ?Improving Temperature Stability of the Elecraft K2 Transceiver 11/15/2002 Rev. H? mod into my old radio. It?s going smoothly except for confusion on my part about one of the capacitors.

The original C174 is to be removed, it is marked ?331? which is 330 pF. 

The replacement in the kit envelope is a ?390? 39 pF cap. But the instructions are confusing, because they say that the replacement should be 82 pF. And then, according to the instructions, if that turns out to not be enough, you can add more capacitance up to 200 pF at C174?or if desperate, add turns to the toroid L33. 

My guess is that somewhere along the line the number of turns on L33 was changed to match a 39 pF cap, and the instructions fell behind. Does that make sense? Or should I hunt down an 82 pF cap?

Thanks for your support!

Doug, W0UHU.

Sorry, no.  Use RCA for both or AUXBUS for both. It?s OK to have an AUX cable from K3 to KAT500 for freq and band info.  But you?ll need to also run an RCA cable from K3 to KAT500 to break the amp key line.

Doug,

I have doubts that the toroid for L33 has been changed.

C174 should be 82pF - call support to get a proper capacitor.
Do not remove turns from L33.

The BFO should come into range with those values.  Check the high and 
low frequencies before doing anything else.

73,
Don W3FPR

I was disappointed to see the pricing for the K4. I thought the base K4 would be in or around $3500 to $3700 and perhaps $500 or so to go to the K4D. As it turns out, another $900 for the K4D. These prices do not include the ATU ($400) or even a hand-held Mic. The total for the K4D that I was thinking of purchasing would have been almost $5470. (+shipping ??) it?s out of my price range. It will be interesting to see what the K4HD goes for. I?m glad that I had my $1500 deposit refunded several months ago. I have to wonder if one will really be able to tell the difference between any K4 and the FTDX101D which can be purchased for under $3000 and includes the ATU and a Mic???? 

 I hope you folks enjoy the K4 as I?m sure it will be a great radio. I will continue to use my K3s as the price for that fine radio is dropping like crazy and has allowed me to pick up a second one for a surprisingly low price.

I have not delved deeply into any of these modes, but I have related experience. PSK is Phase Shift Keying; MSK is a variant of Freq Shift Keying. They are related by the class of math formulas that generate the signals, but differ significantly in operation.

It seems to me that MSK requires much simpler engineering than PSK. In days of yore, this would have been important, but with so much processing embedded on chips these days, it seems to me to be less important.

I'm sure that there is a wealth of info on the web, but a handicap may be point of view. OTOH you will find the math tedious to wade through, but will give you a good understanding of both. OTO, I have not seen a good comparison of the two that addresses the engineering costs versus the performance of each.

No.  MSK is two tone FSK where the shift is one half of the baud
rate.  For example, if one were using the amateur 45.45 baud, the
shift for MSK would be 23 (22.725) Hz.

8PSK is phase shift keying with 8 states (0, 45, 90, 135, 180, 225,
270, 315 degrees).  8PSK is a form of PSK along with BPSK, QPSK, etc.

Dave,

	I understand your disappointment, but in reality these little toys of ours cost money to design and produce.  Just for fun I googled the K3 and that a posting from 2009 eluded that a loaded K3 in 2009 was $3700.  In today's money that is 4,522.73.  The 1000$ plus price of the K4 line doesn't appear to be unreasonable considering the effort that has gone into its design and new features.  

	Unfortunately, in our world nothing of quality ever seems to be free.  I'm mortified every time I go in and buy a new car.  I don't buy cars often, but each time I do the prices have more than doubled.  My first new car was 6,800$, then 15,000$, $30,000, and the last did not quite double rather 40,000$.  (Our previous car was destroyed in a wreck and replaced sooner.)  And worst yet not one of the cars had a resale close to what we paid for it.  

	The bottom line here is that you have to pay to play.  If you find something that works for you be happy with the experience.  In my book anything that give you the experience is what's important.  

YMMV

73

I was disappointed to see the pricing for the K4. I thought the base K4 would be in or around $3500 to $3700 and perhaps $500 or so to go to the K4D. As it turns out, another $900 for the K4D. These prices do not include the ATU ($400) or even a hand-held Mic. The total for the K4D that I was thinking of purchasing would have been almost $5470. (+shipping ??) it?s out of my price range. It will be interesting to see what the K4HD goes for. I?m glad that I had my $1500 deposit refunded several months ago. I have to wonder if one will really be able to tell the difference between any K4 and the FTDX101D which can be purchased for under $3000 and includes the ATU and a Mic???? 

 I hope you folks enjoy the K4 as I?m sure it will be a great radio. I will continue to use my K3s as the price for that fine radio is dropping like crazy and has allowed me to pick up a second one for a surprisingly low price.

I have the FTdx101D. It wasn't made by workers in America and I don't have a pipeline to the designers. Those two things alone might be considered worthy of the extra expense. But K4 performance will be proof of the pudding.

IIRC the price for a base K4 was always predicted to be ~$4K.? I'm on the "no 
deposit" list (I think) so my dismay is the extended delivery time.? My 79th 
birthday is later this month and I had hope of treating myself.? But based on my 
experience of being the first kid on the block to have a K3S my time frame to 
buy was one year after deliveries started.

If I simply had to have a new radio now, just to have a new radio, I would buy a 
TS890.? Two things have stopped that (for now), the less then stellar NB/NR 
performance and, this is going to sound anal, the lack of rear panel phone and 
mic jacks.? I dislike cables dangling out of the front of a radio.

Eric/Wayne,

Now that final prices on the K4-line are posted, for factory-built 
models, can you provide a ballpark on what the price difference will be 
for the kit versions? I realize we're still probably several months out 
from the kits being ready, but it would be nice to know how to start 
saving for when they *are* announced.

Ian,

Due to the pandemic and fires the kit version will be delayed longer than we'd hoped. The kit requires additional documentation and manufacturing/shipping procedures, and unfortunately the personnel involved (including me) have been preoccupied.

Sorry I can't put a date on it. If you choose to convert to factory assembly, it won't impact your position in the queue.

I realize we're still probably several months out from the kits being ready, but it would be nice to know how to start saving for when they *are* announced.

Wayne,


I completely understand the challenges with getting the kit version ready.
I don't have a prepaid order and am perfectly willing to wait  (although,
admittedly, with baited breath :-) ) for the Elecraft team to be able to
get all the pieces and parts of the kits ready to go, safely and
efficiently.

I am just curious about the estimated cost difference between the factory
version and the kits. I want to start putting aside my pennies now, and
want to have a somewhat reasonable target.

I hope for everyone on the Elecraft team to be and stay safe, both from
COVID and the fires.

73 de,

Ian, NV4C

Message-ID: <CAEPKcUmMUMexKRM3PzdyNH1Lo_qTUYMMpHdAThEvoJp0rwcZJA@mail.gmail.com>

It is my humble opinion that a good start  to think about for the price to
save money for a Elecraft K4 Kit is 10% below the cost of a full factory
assembled unit.

 I've been in business for 40 years, and looking at many units, 10% below
is just about right. You must realise that with the K4 and both the K3/K3S,
the circuit boards were compartmentised to the extent that the biggest part
seemed to be assembly of the unit inside the chassis, and testing.

And the KX2/KX2 and the KXPA100 are in the same class..

It's variable, over a wide range (25 to 150 dB).

Hold on a second there, are pre-orders for K4 kits being accepted? If so
I've got a check to write...

If they weren't before, then they aren't now, either...yet. Sorry for any potential confusion.

Well, let?s think about this one a bit.  I for one was not disappointed with the pricing; I think they did a super job.

I have a K4D on first-group order for $4700.  The new price adds $300.  I?m ok with that due to the extreme circumstances involved with getting parts, etc.  But there?s another way to look at it.

To get a rig from Elecraft pre-K4 such as the K3S, compared with the K4D, you would have to add a K3S SUB RX, synthesizer board, at least one CW or narrow SSB filter (or both), the I/O board for all the antenna connections, a P3, a P3 SVGA option, a P3 TX monitor option, a digital voice recorder.  And, I?ve probably forgotten a few, such as the K4?s ethernet connection and all that implies.  

Throw in the extras offered by the K4D and man this is a great deal.  For example the P3 cannot compare with the display on the K4(D).

Throw in performance and it?s even better.  

Enjoy the hobby whatever you choose to get.  Fun is the name of the game.

73,

Plus the K4 has a large, full-color, touchscreen display, Ethernet LAN, 
several USB ports, flexible antenna switching, etc. And it's all 
integrated in one box.

I agree Gary,

I think the price corrected for inflation and performance has actually 
dropped compared to my fully loaded, dual loaded K3 nearly 10 years ago 
( and sold keeping my single receiver K3 which I upgraded as far as 
possible.) So I was comfortable with the price.

I'm in the group 2 bunch.

Subject: [Elecraft] K4 sound card capability
Message-ID: <026300E8-CFBD-459B-A823-AA0C6BCADDA9@comcast.net>

I have a KX3 which connects to a signalink that connects to my computer for digital modes. 

I have not owned a K3(S).  I assume the K4 has an internal sound card to take the place of the signalink but I don?t know how it interfaces to my computer and it?s programs. Is the only thing needed a usb connection between the K4 and computer?

Hoping to see my K4 by year?s end.   I?m near the end of Group 1 and have no idea how many are in Group 1. 

Thanks!
73,
Terry

Absolutely!

My INITIAL order for K3s w/ P3, etc. was: *$4387.87 in 2016*.
Add in *$570 for more filters* over the years (AM, FM, and HF)
THEN in Dec 2019, I did a final "fill it up" order because I saw the EOL 
coming on things: *$2435.48 fo*r
*SubRX**
**??? Gen Coverage and filters for SubRX**
**??? 2 Meter module and REFLOCk board**
**???? Pair of Speakers*
------------------------------------------------------------
All-in, not counting maintenance costs or anything else:

*$7303.35 for a fully outfitted K3s/P3 with dual Receivers and Gen 
Coverage thru HF to 2 meters.*

The K4 looks a LOT more reasonable than one might think from my perspective.

The K3S, K3 with KIO3B, and K4 all have built-in "sound cards".  I've used this capability for FT8 and RTTY with AFSK. 

The single USB cable makes available a "sound card" and a virtual serial port that looks to your PC like an RS-232 serial port.

I have a KX3 which connects to a signalink that connects to my computer for digital modes. 

I have not owned a K3(S).  I assume the K4 has an internal sound card to take the place of the signalink but I don?t know how it interfaces to my computer and it?s programs. Is the only thing needed a usb connection between the K4 and computer?

Hoping to see my K4 by year?s end.   I?m near the end of Group 1 and have no idea how many are in Group 1. 

Thanks!
73,
Terry

Two questions:

Can the K4/10-F be field upgraded to 100 watts at a later time?  That is to say, will there be upgrade kits available not too long after the basic rig is . . . just in case?

Will the K4/10-F play as well with the KPA-1500 as the K4/100 will?  If so, what RF output from the amp could be expected?

Terry,

the K4 will connect with a USB cable to your PC, you will not need a
Signalink.? It will have a much better soundcard than the Signalink
provides.??? Since the K4 manuals are now online, you can download the
PDF and see for yourself.

FWIW .. you don't need the Signalink with the KX3, just a set of stereo
cables, and a USB soundcard.

Another way of looking at this is through the lens of history and 
inflation.  In 1969 a set of Drake twins (R-4B, T-4XB, MS-4, AC-4) cost 
$1149.85 (in the 1969 Lafayette Radio catalog).  That translates to 
$8136.60 in 2020.  I daresay that the K4's features and performance are 
just a tad bit better. ;-)

Best guess with 10 W drive and a completely stock amp:  250-400 W, varying by band. 

I don?t have a KPA1500 on my bench at the moment. No doubt someone will weigh in with a better estimate.

Yes, same as the USB CAT and sound card for the K3S so you will just 
need a usb cable to your computer. Standard drivers so no need for a 
driver disk like some other radios.

Best to save a HEAP of pennies, Dollars and Euros,  Ian!...Neil N4FN

I am just curious about the estimated cost difference between the factory
version and the kits. I want to start putting aside my pennies now, and
want to have a somewhat reasonable target.

I hope for everyone on the Elecraft team to be and stay safe, both from
COVID and the fires.

Subject: [Elecraft] K4 vs. K4D Question
Message-ID: <01b401d69a94$b57cca60$20765f20$@comcast.net>

I am rather late in the first prepay group and requested a K4.  I was
strongly considering upgrading to the K4D when I got the call that my rig
was about ready to ship.  Now that the pricing is out, I see that it is a
$900 difference.   That gives me a bit of pause, not because it isn't worth
the price, but because I am not sure my style of operating would justify it.

 

I would appreciate it if some of you with more experience in such things
might be able to give me some insights.  Here is my operating information:

 

1.	I am predominantly a CW operator
2.	I do enjoy working DX contests, but as a hunt and pounce guy, just
looking for countries I may have not worked before.  I am not a serious
contester trying for points and awards.  
3.	For non-dx contests, I operate at or near QRP levels to see how well
I am getting out on my antennas.
4.	I am predominantly a rag chewer on CW,  or casual operator for
regular CW QSO's.
5.	I have two antennas, one a Yagi for 20, 17, 15, 12, and 10 meters.
The other is an EFHW  for 30 (with tuner) 40 and 80.

 

I am not sure diversity receive would be all that useful with such different
antennas.  The yagi is useless as a receive antenna on 30, 40, and 80, and
the EFHW can receive and transmit on the higher bands, but does not have
directionality or gain, and the 40 and 80 meter bands are predominantly for
local and US. operations.  

 

I think diversity receive might be useful with QSB conditions if I am
operating on 20 meters and up and letting the EFHW try to help, but that one
advantage would not be worth the difference in price for the K4D, especially
with the band conditions we currently have.  

 

If I am going to check a different band, I usually just change bands and
look at the panadapter to see how active the band is.  Not sure having VFO B
connected to a different antenna, (like working 20 on the Yagi on A and
possibly working 40 on the EFHW on B would gain me much.  I would most
likely just use VFO A, and change bands.

 

I look forward to your thoughts and what opportunities I might be missing by
not getting the K4D.  I would guess there are others in this group that
would be interested in the responses as they make the same decision.

 

Thanks so much, and 73,

 

Terry, N7TB

Given that the K4 can be upgraded to a K4D in the field, why don?t you start out with the K4, how it goes, and decide to upgrade later.

Hello all,

 

I am sorry if I miscommunicated.  I have received several private emails
thinking I have been called and expect delivery of a K4.   I have NOT been
called.  I was just referring to when that time comes.  I don't expect a
call for months.  I was very late in the first group.

 

I still need some feedback to help me make my decision when that time comes.

Just finished operating the California QSO Party as K6VO.  I received a
report of a bad CW chirp and have a recording of how that sounded.  Has
anyone had any issues with K3s chirping?  At this point it's only reported
on 80 meter CW, so it may be RF getting somewhere.  I think my power supply
is good.  I have not been able to recreate yet listening to a remote
receiver.

Any initial thoughts appreciated.

Terry,

I am most likely at the end of the group, too.
I originally ordered a K4.
I change the order this past spring, to the K4D.
I "don't need" a K4, even.? I have great fun wit a KX3 + PX3 + KXPA100...
I wanted a home station so that the KX3 was my portable station.
I looked at the "D" upgrade as, an "Easter gift" and "the boss" approved.
Yes, I would like to have it for Christmas even if it is a year late.
And it my be Easter 2021...

And as my wife says about buying a dress, it isn't just the dress, it is 
also the accessories...
The accessories will be added this coming Christmas.? Computer, 
Monitor(s), upgrade the coax, and maybe 500 watts + AC power upgrade 
(100 year old house).

73, steve WB3LGC
you can't take it with you.

Dear Brain-Trust,
	I currently use RUMLog and/or SkookumLogger for my contest work (K3S and a Mac)?. 

	I recently tried to work the RTTY Contest, but found the FLDIGI interface not very smooth, could not get the integration with RUMLog working, and then found that COCOA-Modem is out of compile life?. 

	So ?. Suggestions please ?? All acceptable except ditching the Mac.

	Regards

Good Evening,

 ? I had noise from a storm north of me during the twenty meter net.? 
QSB was at medium which sometimes helped.? The forty meter net had 
stronger signals than last week with less noise.? There were folks in 
the CA contest above and below me.? It was hard to find an opening on 
twenty meters but on forty I had better luck.

 ? On 14050.88 kHz at 2200z:

K6XK - Roy - IA

K4JPN - Steve - GA

AC5P - Mike - OK

K1SW - Dick - CT @ 12 watts


 ? On 7047.5 kHz at 0045z:

K6PJV - Dale - CA

K0DTJ - Brian - CA

K6XK - Roy - IA

K1SW - Dick - CT


Smoke reports were encouraging.? High haze in some spots, foggy mornings 
in others.? Hopefully we can stop coughing soon.? The cloudy weather off 
shore may come inland and douse the fires.? I keep hoping for the sun to 
become active again too.? Half full at all times ...

 ?? Until next week 73,

Hi:

I fully concur, when you look at the prices we paid for the K3/K3S and 
all those extras, the current price of the K4D seems like a good price 
to me. Sure hoping that my K4D will arrive before Xmas. Only time will 
tell, it will be almost a year since I purchased the K4D. Fingers are 
getting itchy, so much that I went out and bought a couple of those 
stylus pens just for the rig.

As there is not even a block diagram published, I don't know the answer, 
but ideally one would not want baseband analogue audio anywhere in the 
path, so one would not want a sound card, integrated or not, but rather 
direct access to a digital feed from the DSP.

Neil,
When I bought my K3 in 2008 and later on when I added the rest of the
K-Line, I bought kits. Did the same for my KX3 and KXPA.
They were not bought to save dollars but to familiarize myself with the
equipment.
I bought a fairly bare K3-100 - only added the tuner. As time went by I
added all but the TXO and then added some K3s stuff - new synthesizers and
USB interface. Starting with a kit made all of the upgrades a non-event,
even when I had to remove the front panel.

My recollection is that the difference in cost was minimal (a few percent).
My guess was that the cost of not assembling an Elecraft is mostly offset
by the additional packaging and instructions for the kit end user.

I'm probably going to make a K4 my final radio as a 80th birthday present
in a year or two!

Subject: [Elecraft] K4 Power Supply Recommendation
Message-ID: <8FC02753-2A67-4B8B-87BD-DEE8DEE20185@gmail.com>

Hello everyone!

Like most here I am waiting for my K4.  Currently I am running the Power Werx SS30DV from the Elecraft site for my KX3 and Kxpa100.  I was planning on buying another for the K4 but thought I would ask opinions first.  I am assembling my first real HF station and going the cry once route.  I would rather pay a bit more up front and get something solid rather than saving a few bucks now only to upgrade later.  

Given what I intend to spend on the K4, I don?t want to skimp on its PS if spending a bit more will improve performance.  My budget is let?s say $500 and my question is would buying a bigger switching or linear PS for the K4 make sense?  My KX3 PS has caused me no issues and if that is the way to go I am groovy.  

Since my father has passed and I inherited his call sign my wife is being very gracious in allowing me to splurge on this hobby that I have only recently taken back up in remembrance of my SK father.  Help me spend some money while the wallet is open.

My antennas are a Butternut HV 9v vertical, and 3 alpha delta 1/2 wave wire dipoles  80, 40, and 20 meters.  

Thanks!

Assuming the K4 likes a little extras voltage like the K3S (14.2VDC for mine), I have been running an Astron RM-50 linear for 10 years or so and would recommend it or the 35 amp version. ?I modified the voltage sense circuit to follow the voltage at the rear of the K3s to help with voltage drop around a power gate. ?The only time it has been off was for the modification and if the AC power fails.

It powers all of my station accessories with a little room to spare.

The power werx switching supply is also on the bench - bought it before my K3s for VHF/UHF radios. ?It has been repaired once for the choke on the input power lead - it failed and made terrible broadband noise. ?It is 6 years old. ?It has a little higher ripple than the Astron - always has. ?Probably not a big deal though.

My $0.02.

That sounds like a toroid in the Low Pass Filter.  If so, yes you could 
make that substitution if it fits.

 The power system for my K3/P3 consists of a large SLA AGM battery that is float-charged froma West Mountain Radio PGS-40 and an Astron RS-25, which I adjusted to 14.2V to accommodatethe drop through the wiring, the PGS-40 and the RigRunner. This has kept things very quiet for me,and also keeps me on the air through any AC power interruptions, and I use it at both my primaryQTH in south Florida as well as my summer residence in western NC. This should fit your budget.

I also have a Powerwerx SS30DV but I just use it only when I travel to  
the caribbean with my K3S. I home I use an Astron 70 amp linear power  
supply. This is obviously oversized but it was in my shack for a  
decades before buying an Elecraft transceiver. If weight is not an  
issue I would look at the Astron linear power supplies.

Hi,

I have no interest in K4 postings. I have tried all sorts of 
combinations of mail filter setting to dispose of K4 posts without success.

I'm sure someone out there has managed to do this. If so please advise 
how you did it.

Please don't suggest the delete key, I'm familiar with that.

My question is this:  should I strap the QSK M for 2ms hold time after ptt

If you can?t send posts with ?K4' in the title or text to the trash, then there?s something wrong with your mail client's filter.  I?m not familiar with Thunderbird, so maybe there?s an issue there.

I routinely read maybe 20% of the posts I receive from the many (20+?) reflectors I subscribe to. (or .. 'to which I subscribe?,  to use what was once called proper grammar).  In any case, DEL is the best approach, like it or not.  I often read posts that some filter would have discarded .. and learn something useful.  There were even, at times, some senders who?s emails I might have filtered out.  But even those are, far more often than not, highly informative and useful, and I get past the occasional condescension, and don?t.

I know this isn?t what you wanted to hear.

I use Thunderbird on some of my machines, Apple Mail on others.

Because Apple Mail leaves even much more to be desired than Thunderbird, 
I was using procmail on my ISP's server to do all of my filtering to 
mailboxes. Later, the authors stopped maintaining it, and I switched to 
a similar, more up-to-date tool. I recommend that you ask your ISP what 
they have installed. If they're running Linux, then they might have 
Pigeonhole [ https://pigeonhole.dovecot.org ] available.

It's much cleaner to do all of the filtering at my mailbox, rather than 
on each desktop, laptop, tablet, or phone I might want to access it from.

Nope, it's not Thunderbird, which has a rich set of filters to trash or 
transfer e-mails by content of title or body or sender or ...

Mike,

Easy with Thunderbird,

Make a filter for your incoming mail - If the subject line contains K4, 
move it to whichever folder you would like.

That will work as long as everyone puts 'K4' in the subject line.  For 
the rest, you will have to use the Delete key.

Don W3FPR

Have you tried something called Mailwasher. I can set it up with

T-bird works super ... mine sorts my mail into various folders and even 
sub folders.? It seems that enough people put the Elecraft model number 
in the subject line that virtually all mail related to that item goes to 
the right folder.? I've found that using the message body is somewhat 
less reliable as someone may drop a "K4" into an email relating to a 
K3.? I'm sure most other email clients can do this as well including web 
mail clients.? I recommend you concentrate on the subject line and keep 
it simple.

I have also filtered a few "from" addresses directly to trash because 
the emails are often argumentative, political, or otherwise unfriendly.? 
That doesn't happen much on this list.

I just use GMail. I scroll through my emails and look at the subject. If it
has something in it I don't want to read, I check the box at the left.
After I go through all of them that way (not even opening them yet), I
click the "mark as read" button. All the marked emails get moved out of my
inbox to the "read" portion. They aren't gone, I can go back and read any
of them if I want to, but I don't have to read them NOW. I go to the bottom
of my remaining unread emails, open the last one, and read it. Then I hit
the arrow at the top right, and move to the next email. Lather, rinse,
repeat.

Not all that hard.

If there is something that pops up frequently, I create a filter for it,
and just mark it as read. On rare occasions, I make a folder and send the
offenders to Coventry. Other than that, I read pretty much everything else.

It turns out that the 82 pF cap I was looking for in the BFOMDKT kit is actually in the K2ATOBKT kit. 

In addition to some parts consolidation, the Upgrading the Elecraft K2 to Revision B (K2ATOBKT) instructions seem to over-ride or modify some of the instructions in the earlier upgrade kits. Mostly in the area of the sequence of alignment. I will go through all the instructions now to get them synchronized.  :-)

Thanks, Doug W0UHU

Doug,

Do the K2ATOBKT first, and where those instructions indicate, do the 
BFOMDKT and the other auxiliary kits.  That will synchronize them for you.

Subject: [Elecraft] KX3 battery upgrade?
Message-ID: <2d4f9558-eb0b-d7e7-fcf3-bc1ae204feaa@effable.com>

The KX3 is my favorite of my HF radios right now. But one of my 
annoyances is the internal battery limitations.

I always wind up carrying an external 6_Ah or 10_Ah LiFePo4 battery into 
the field when I use this radio, an external charge controller, and 
solar panel. It's not a big problem, but it also should not be a big 
project to improve this situation. The KXBC3 has enough real estate to 
include a lithium battery charger, and even a solar charge controller in 
its space. The amount of battery energy that could fit in-place of the 
NiMH cells could approximately triple the capacity of the AA cells.

So I have these questions:

1) How many of you out there might buy an upgrade which replaces the 
KXBC3 board with a lithium battery manager, and a associated battery pack?

2) Are there any 3rd parties already making anything like this?

Great idea, count me in!  

At first I thought ?The new KXBC3a should be backward compatible to NiMH cells?.  Then I realized ?Who would want to go back??  Then for safety reasons make it impossible to ?accidentally? connect the LiFePo4 battery pack to a KXBC3.

The KXBC3 has enough real estate to include a lithium battery charger, and even a solar charge controller in its space. The amount of battery energy that could fit in-place of the NiMH cells could approximately triple the capacity of the AA cells.

I also always carry a LiFePo4 when I go portable with my KX3.

I'd be interested in moving a LiFePO4 battery into the case and 
removing the NiMH Eneloops that don't seem to provide enough 
voltage or last long enough.

Curious. I?m doing a lot of antenna work right now. I had to remove my 12/17/30m trap inverted V to get my beam off the tower. 

In the meantime, I?m making due with a 20/40/80m trap dipole. 

If I use 12m on the 20/40/80m dipole using a tuner, I?m not having any HI CUR issues, even when running 100 watts.

I think what I?m seeing is an RF in the shack issue. The 20/40/80m antenna feed point is about 70 feet further away than the old 12/17/30m antenna.

I'd be up for that. The KX3 is my favorite radio.  After I got the KX2 and
started enjoying its internal Li-ion battery pack, I realized that the
KX3's internal NiMH battery charger is its worst feature.  I too never use
it anymore and have just switched to a small, external LifePO4 pack.

I have saved URLs to 10 reflectors, but always have opted _OUT of Email_ 
from all of them.? The saved links are to their _archives_ only, viewing 
by thread.? Some, like the Elecraft reflector and all the groups.io 
lists, are continuous.? Other archives for lists like CQ-Contest, RFI 
list, etc. require changing the month in the saved URL when a new month 
appears.? Not a big problem... takes only seconds each month.

This way I just click on the bookmarked URL for the reflector that I'm 
interested in and view the threads.? I probably view 10% or less of all 
the posts on the Elecraft reflector.? I can't imagine actually getting 
Email from all the posts or having to set up filters for new ones that 
appear that I'm not interested in viewing.? It makes these reflectors 
light years easier to manage as compared to getting all those emails!

When you configure a WSPR transmitter, how do you decide what is the 
best frequency to use within the 200 Hz. WSPR range? I looked at the 
spot database and nothing jumped out at me.

Further details: I just assembled a QRP Labs U3S standalone WSPR 
transmitter, with a GPS receiver. I will probably start on 30m because 
that is the band that is available when all the relays in my antenna 
switching system are open, so it will be easy to let it run while the 
rest of my station is off.

Sorry for the OT post, but there are lots of smart guys out there! 
Answers can be off list.

I don't have a K3 but Elecraft stores KAT 500 and KPA 500 config files at:

(local disk name - typically C:) / Users / (your user name ) / Appdata / Roaming / Elecraft

I expect you will find a K3 folder there.

The KX3 is my favorite of my HF radios right now. But one of my annoyances
is the internal battery limitations.

I always wind up carrying an external 6_Ah or 10_Ah LiFePo4 battery into the
field when I use this radio, an external charge controller, and solar panel.
It's not a big problem, but it also should not be a big project to improve
this situation. The KXBC3 has enough real estate to include a lithium
battery charger, and even a solar charge controller in its space. The amount
of battery energy that could fit in-place of the NiMH cells could
approximately triple the capacity of the AA cells.

So I have these questions:

1) How many of you out there might buy an upgrade which replaces the
KXBC3 board with a lithium battery manager, and a associated battery pack?

2) Are there any 3rd parties already making anything like this?

Check the Activity section of the WSPRnet.org site: you can see which 
slots stations are occupied. Also, check the received signals on your 
display and select a vacant spot.

But it doesn't matter very much-- wspr station transmissions occur at 
random intervals so that stations on the same frequency will not 
consistently interfere with each other. This assumes everyone has 
selected a reasonable Tx Fraction, not 100%.

Thanks everyone for the replies and advice; much appreciated.  This is exactly the kind of question I would bring to my SK father so it was very nice to read the advice posted as if it were coming from dad.  It was all practical interesting. It made me miss having these discussions in his shack while he was building some project.  

I have since ordered an Astron RS-70M-AP.   It?s a big old (48 lb) linear and more than I will probably ever need.  The 70 was only $10 more than the 50 on HRO and it has a cooling fan where the 50 does not so I thought it may be more robust.   I plan to run all of my HF from this amp (KX3, KX2, and hopefully soon a K4).  I?ll use the PowerWerx SS30DV switcher for my Yaesu FTM-400DR VHF and UHF in he shack.  

Thanks again everyone!

LiFePO3 can be as heavy as KX3 and defeats the purpose of KX3 if weight is
concerned.

I use 4S2P Lithium Ion. Like:
https://www.batteryspace.com/li-ion-18650-battery-14-8v-5-2ah-77wh-2x4s-s-rechargeable-battery-pack-6-24.aspx

Since it has 16.8V peak, I charge it via a diode for 16V. A diode internal
to KX3 makes it 15.4 V max and thsi is what the internal meter in KX3 shows.
This is 12% over 13.8 V. Lasts a long time. Full power up to 15W. No problem
in > 5 years.

True, but LiFePo4 are widely available, and more tolerant of careless 
charging. They're still better than the internal NiMH cells.

Are you saying that have you installed this battery pack in place of the 
AA cell holder inside the radio?

Are you saying that you're using the KXBC3 to charge your lithium pack?

Do you charge this battery in the field with either a solar panel or the 
accessory (cigarette lighter) socket in a car?

You get what you pay for. Yaesu has been making very dirty radios -- 
clicks and splatter have been the rule. Elecraft rigs have always been 
very clean on CW, less so on SSB, but nothing like Yaesu on SSB.

Agreed on all counts. I read more than two dozen email reflectors, and 
Thunderbird makes it easy to to sort each into its own mailbox. I've 
never used it to sort topics, but agree that the Subject Line is the 
ideal sort range. I use subject line sorts to sort to the mailboxes.

Thunderbird is very versatile -- it can be set to read by thread, or by 
individual emails. I strongly prefer the latter, because it's easier to 
delete stuff that strays off topic.

I've never done that -- my delete key works fine.

I use it only for my gmail address. Compared to Thunderbird, it's brain

Since I don't have to schlep the thing on my back like those who backpack
to their field ops sites -- I use a dolly I keep in my van for the purpose
-- I use a Talentcell 12Ah 12v battery. I connected a coaxial connector
cable I got from Elecraft to it, and it powers a lot of my devices. The
only issue is that it's about 1.35 kg, so it would be a significant weight
to carry, say, in a backpack. That's one reason why I worked up my USB-C PD
smart cable, as the PD power bank I have for it is a lot lighter.

I never had a failure with Li-Ion batteries bought from batteryspace.com.
They are connected externally to KX3 and charged by an AC charger.   They
last so long that seldom I need to charge during a  trip. 
I use LiFePO3 for my 100W radio.

Alan, thank you.   That's an fascinating bit of history, always interesting
to me (at least).

A side note: the FM component of WRR (in Dallas) still is on the air.  It's
the only Classical Music station in DFW (that I am aware of).

?Beginning with the introduction of licensing in late 1912, the standard practice had been to assign call letters<https://en.m.wikipedia.org/wiki/Call_sign> starting with "W" to radio stations east of the Mississippi River. However, KDKA happened to receive its assignment during a short period during which land stations were being issued call letters from a sequential block of "K" call letters that had previously been assigned only to ship stations. Although the original policy was restored a few months later, KDKA was permitted to keep its non-standard call sign.[11]<https://en.m.wikipedia.org/wiki/KDKA_%28AM%29#cite_note-11>?

In a parallel thread VP8NO wanted to filter K4-related posts...and now
there's this!

Folks, the correct way to read this reflector is to turn of email from it
entirely. Instead look at it here, only clicking on the links of interest
to you:

If you try to set up email filters to improve the S:N ratio, you'll soon

Maybe correct for you, not for me and many others. The minimum time I
have to work the mouse, the happier I am.  As we children of the '50s

Albert Einstein is widely credited with saying, "The definition of

Terry,

I could use your self-description by adding "used to" in the context of
contests (I'm up to 297 confirmed and contest opportunities for the rest
are slim to none).

Then I'd add: "lives on tiny urban/city lot surrounded by both horrible QRM
and hills."

My antennas were as you describe: a 2-el 5-band beam up a whopping 30 feet,
and a wire running through and around trees like a demented pretzel at that
same height. And you're right, while diversity thrives on differences, it
doesn't thrive on THOSE differences.

In my quest for DXCC on 40 and 80, I'd added a pair of DXE active receive
verticals and noise canceller in a failed attempt to phase my way through
the s5-s6 noise wall - there were far too many noise sources for
cancellation to be effective. So I was left with a receive antenna that
didn't work all that well in noise-hell, either.

Then, after letting it sit mostly unused for 6 months, I tried diversity
reception.

Wow.

When you're working down near the noise, QSB can kill many a QSO. But even
with my minimal antennas, the way signals "float" as the RF rotates through
polarizations is remarkable to hear: a signal that would otherwise be lost
often comes up in one ear just as it drops in the other...  I recently
worked VK6LW when he was unreadable on either the long-wire or the receive
ant, but was readable with diversity turned on.

It sometimes seems like the difference between mono and stereo music.

Anyway, diversity reception was unquestionably the key to 80M DXCC from
this QTH.

Point is: if my K3 hadn't already had that second receiver, it's unlikely I
would have added one just to try. So if you can swing the cash - like a
good scout: "be prepared."

It's mostly the same culprits who initiate off topic posts, so filtering

Another interesting fact about US broadcast station callsigns is that back before U.S. maritime radioTELEGRAPHY ended (except for rare historical exercises) in 1999, most US-flag merchant ships with radiotelegraph stations were assigned four-letter callsigns beginning with K or W.  There are no longer many such calls that are still assigned to merchant shipping.  A quick random search at:
  https://www.itu.int/mmsapp/ShipStation/list
found KPLB, WGDX, WQUI.  Twenty-five years ago and earlier there were hundreds of US ships whose radiotelegraph station had callsigns of broadcast station format.  Maritime radiotelegraph coastal stations like KPH, WCC, WOM used the same call format as some broadcast stations like KSL, WLS, WOR, WSM, etc.  Maritime ship radiotelegraph callsigns were not affected by location for assigning K or W as first letter.

Forty years ago I held a commercial radiotelegraph license.  After I received ham call KK5F, I day-dreamed about having a ship with maritime radiotelegraph call KKHF to match.  :-)

"You get what you pay for. Yaesu has been making very dirty radios --"

I'm not sure I see the connection between part 1 and part 2. I paid for a Kenwood TS-590S. Actually I have two of them. I don't think this radio ever sold for more than about $1,600 and to the best of my recollection it's not high on anyone's dirty transmitters list (assuming a Chinese TCXO was not fitted).

I have never felt I could have worked more DX with a "better" rig.  Better antennas - sure, better rig - no.  My flying sucks up all my money.  None left for K4.

Hi.

My K3 seems to switch to AM around 5 MHz even though the display says 
DATA. And the filter highlight on my P3 also switches to the AM width 
around tuned freq.

Earlier I had tuned to 5 MHz WWV to do a sound card calibration and 
switched mode to AM. Now was trying to test my fldigi FMT Modem against 
5 MHz WWV so switched to DATA. Still shows as if I am in AM mode.

Anyone have an idea what is happening?

As others have posted, the convention was that Broadcast stations east
of the Mississippi were given W call letters and west of the Mississippi
were given K call letters (with noted exceptions).  Ocean-going ships
had the opposite according to their home port of registration.

When I started doing ship safety radio inspections in 1967 there were
600+ such vessels in the US registry, not counting the WW-II-era Victory
ships that were owned by the U S Maritime Commission and were being
pulled out of "Red Lead Row" (deep storage Reserve Fleets) and operated
under contract to support the Vietnam War going on at that time.  New
ship radiotelegraph stations will be licensed as part of the ship's
radio station license under the now-standard XXXnnnn call letters.

AND, ( stated as kindly as I can) You'll wear out the manual before the
radio.
I was a Yaesu fan-boy, putting up with the seemingly endless menu's all
through the various FT-1000 versions, then came the FT-2Kaput.
I'm cured now and am waiting to save a few buks on the K4Kit.
Guess I should probably sell my couple year old K3S package eh?

You get what you pay for. Yaesu has been making very dirty radios -- clicks
and splatter have been the rule. Elecraft rigs have always been very clean
on CW, less so on SSB, but nothing like Yaesu on SSB.

Tom,

You likely have the 6 (or 13) kHz filter enabled for both DATA and AM 
modes.  Use K3 Utility Filter Calibration to change it.

Thanks Don.

I had changed nothing in the radio. Had been working just fine up to 
this afternoon! Not just the filter, the radio is in AM mode even though 
the mode says DATA.

Will go look at the filter set up!

Message-ID: <1602028064846-0.post@n2.nabble.com>

I bought a GMYLE Mini USB keyboard a while ago and tested it with the PX3 and
it worked.Then I put it aside and concentrated on my Morse speed and
learning to use a bug.Today it didn't show the "K" when I connected it. 
However, it did connect if the USB plug was pulled out around 1/16".I
applied a narrow band of heat-shrink to the USB plug and now I get a firm
connection, but the plug cannot be inserted far enough to disconnect.I don't
know if this was "tolerance stacking" and a special case or if it might
apply to other USB keyboards.If you are having intermittent connection
problems with a USB keyboard, you could try this before buying a different
keyboard.

You're right, Andy  - I've heard from tops ops that own them that the 
TS590s are very nice rigs, and ARRL Lab tests show them much cleaner 
than ICOM and Yaesu. I've recommended it to several hams who can't 
afford Elecraft. (Although used K3s are getting to be a real bargain!).

Given that this thread very plainly contains "OT", for Off 
Topic, in the subject line, anyone wanting only information 
about Elecraft equipment should have already filtered it out. 
Many posters are careful to label their off topic posts with OT.

Many are also careful to label their posts with the specific 
piece of equipment they are discussing. Of course, we have 
subject drift, and people aren't super good about changing the 
subject line when they change the subject.

BTW, I read almost everything on the list because I consider it 
to be a community and I like to try to help the people in this 
community when I can.

Subject: [Elecraft] K3 off frequency?
Message-ID: <61420429-1B54-41E9-8850-EA87F9DDB426@me.com>

My K3 (with all S upgrades, ser #170) stopped working over the weekend.  I noticed that on 80m, while the frequency on the rig was 3574, the frequency reported by KAT500 was 3152 (or so).   No output on any other band.  I then checked reception of WWV - no reception of the 10Mhz signal.  I fed in a -50dBm signal at 3574KHz.  No reception.

I am going to crack the case on the weekend.  

The only think I can think of is that something has shaken loose as the rig was transported by car a while ago.  Given the odd frequency, I am thinking that it may in the LO chain.

Any thoughts?

I'm the guilty party who started the original off-topic thread. Sorry 
about that!


If you're using the Thunderbird email client, the following is the 
easiest way to automatically remove unwanted messages:


1. Click on the message.

2. Click on the menu icon (three horizontal lines) in the upper right of 
the window.

3. Click on "Message" then "Create Filter from Message".

4. Change the "From" field to "Subject". (Or leave it at "From" if you 
want to flag the sender rather than the subject.)

5. Change the "Is" field to "Contains"

6. In the next field, enter "OT" or whatever text you want to flag in 
the subject line.

7. In the sub-window below that, choose the folder you want to send the 
message to.? (Perhaps "Trash"?)

8. Click "OK"

Lack of 8 volts kills the synthesizer.  I made a few notes when I did the repair. I have attached my notes to this message. Possibly it may be of help to you. I showed where the synthesizer frequency outputs are and what levels to expect.  The K3 I fixed was also a low serial number around 375 as I recall.

Here is the list of stations that checked in to net on Sunday, October 4, 2020. A big thank you to the relay stations who always help out receiving many stations. Thanks to all who have to bear with us due to difficult propagation. 

Here are the SSB Nets that take place on Sundays. You do not have to have an Elecraft Radio to check in to the net. We ask for the call sign, name, state, type of radio. If it is an Elecraft radio the model and serial number. For the 80 M net, we may have to change the frequency at times if another net or group is using the frequency. Please tune up or down to find us. Eric WB9JNZ

When I plug in the 13.8V PS the radio shows 13.8V for only 1 second and
drops to 10.4V. Eneloop batteries all OK 1.29V individually. Running a 4
hour charging cycle it turns off when voltage reached and shows the
dropped voltage. When batteries removed the voltage shown on display 13.8V.
Is it known failure, what can I do to fix it?

Istvan,

There are protective diodes in series with both the internal batteries 
and the external supply, so the fact that the KX3 shows 0.3 to 0.4 volts 
lower than the external supply is normal.

Hello Elecrafters,

I had a similar problem with a K3 this past March. My brother had his K3 
die and I offered to look at it for him.? He claimed that he could only 
hear things on part of 80 meters. All the other bands were dead on RX 
and TX.? When I checked it, I found similar symptoms. At one point it 
started working again normally, then, with the next power cycle, it died 
again.? The problem was traced to the synthezizer.? Board layout 
diagrams are a bit sketchy for troubleshooting. I contacted Customer 
Support and a wondeful tech guy gave me some pointers on where to look.

The problem, while seeming to be serious, turned out to be a simple 
fix.? The 8 volt three terminal regulator mounted on the side panel had 
rolled over and died.? When I got everything running again, I made some 
notes (complete with pictures and arrows )? I tried to attach it to my 
response to N2RD and the reflector, but the? e mail was rejected as it 
was too big. I think the notes are pretty good as it shows where to look 
for voltages involved with the synthesizer, as well as LO signal levels 
and frequencies, on each band for the receive and transmit paths.

Is there a simple way I can post these notes so all can see it? I did 
send them to N2RD to help him figure things out.? If anyone is 
interested, I can send them the note. It is a WORD document and is about 
3.2MB in size.? The size is due to color pictures of the circuit boards 
showing the test points etc.

Subject: [Elecraft] K4 replacement?
Message-ID: <B386B38D-E50C-4860-8C1D-B81D1A1EA24F@mac.com>

I am a bit depressed about the lack of feedback from Elecraft about the K4. I?ve sent emails to Eric and Wayne, with no response. Telephone calls to Elecraft seem to indicate they have no idea either about what is going on. I am in the first group for the K4, but think this is unlikely to ever ship!

In the meantime, I am running my K3/P3/KPA500/KTA500. Works well.

So, the purpose of this email is to generate information about what I should purchase to replace the K3. My predominant operation is high speed CW, so ask is very important to me.

Maybe the Kenwood? 

Your thoughts are solicited!

Tom,

The Kenwood TS-890 is on my short list should I grow too impatient waiting for the K-4.  I have almost pulled the trigger many times on it.  

That said, earlier in this waiting process I bought a Flex 6400M and almost immediately regretted it.  Great radio, but not an Elecraft and not for me.  I sold it and am now focusing on working my KX3 and KX2 QRP in the field.  Getting a new shiny transceiver now is wonderful, but if it isn?t the one you really want, you may have buyers remorse later.  Luckily I only lost about $400 on my Flex folly.  I?m waiting for the K4 and I?m in the second group so I still have a long wait.  Maybe this time next year.

Thanks. I finally got ny refund for first group K4D. Was looking at a 6400,
because I don't do cw right now, but will take a look at the 890 as well.

Get a KX2.  It will probably be at least a couple of years before announcement of its replacement will make it instantly obsolete and unusable in the manner that the K4 obviously has made your K3 for you.  :-)

I received about the same number of similar comments off-list as you've 
seen on-list. (Thanks!) So at least twenty of us would eagerly buy such 
an upgrade to the KX3 (see my previous post, below).

I suspect that the Elecraft folks don't have the bandwidth to work on 
such a thing right now. If we want it bad enough, we might need to take 
it into our own hands.

If any of you out there have mad CAD skills, and are looking for a 
project, contact me off-list. Perhaps we can do a little feasibility 
study by drafting a preliminary design of a KXBC3 replacement.

I believe Rose posted previously that she would not be making soft cases for the K4.  That may have changed, though.

While I have both KX3 and K3/P3 DX cases from Rose, I?m probably going to purchases a Pelican or similar for the K4.

I've read the specs but I can't translate that into practical terms.  I
suspect the K4HD is a better choice when you are in a multi transmitter
environment like FD or a multi-multi but are there other situations where
the HD is a better choice?  I do have a few local hams and I have
encountered some problems when we are on 6 meters but otherwise no real
interference or rx blocking problems.  I have  K3S.

 

Do any of the beta testers have a K4HD?

Peter,

The K4HD has been delayed due to all the recent challenges (pandemic, lockdown, fires). 

The K4D has been tested in heavy contesting conditions with stations in line of sight each other, without any kind of overload issues reported. Like these operators, most will find they don't need the HDR module. For those who do, it'll be retrofittable at any point in time to convert a K4D into an HD.

Subject: [Elecraft] K4 built-in operating manual now available
Message-ID: <FA5E1E47-0AD9-47BB-B121-1B80D46CDD9F@elecraft.com>

The K4 has a complete operating manual built in, accessible by taping the "?" icon at the lower left-hand corner of the screen. This is a convenient supplement to the full owner's manual (in progress).

The built-in operating manual has small and large screen formats. It's a hyperlinked .html document that will be continuously updated to reflect the current software level. You can tap highlighted links on the LCD to navigating forwards/backwards as in any browser, or search by entering text using the on-screen keyboard. The "LAST CTRL" button allows you to go directly to information pertaining to controls recently used.

Several early reviewers have vetted a draft of the built-in operating manual (by viewing it with a browser on a computer or mobile device). It has been revised and is now posted on our website, at:

https://ftp.elecraft.com/K4/Manuals%20Downloads/K4%20Built-In%20Operating%20Manual%20rev%20A-7/K4BuiltInOperatingManualrevA7.html

Further suggestions or comments are welcome.

========
  NOTE
========

The built-in operating manual has a limited number of illustrations, since it is intended to be used from within the radio itself, which provides context. Another way to familiarize yourself with the front panel is to read through the "Introduction to the Elecraft K4", at:

https://ftp.elecraft.com/K4/Manuals%20Downloads/Introduction%20to%20the%20Elecraft%20K4,%20rev.%20A-7.pdf

I have just noticed that after replacing my K3 with a K3S my P3 no longer
shows the center frequency of VFO A (7.234, 14.234, etc,).  I cannot find
any info in the manual or the Fred Katy book.  Could I have miss-cabled or
changed a menu option inadvertently.  All other functions are normal.

 

Thanks in advance for any info,

Just got off the phone with Eric. The K4 is steadily shipping, and they are working diligently to get through the huge numbers of orders.The company is in fine shape, thanks to the huge numbers of orders.

Eric will be posting an update later today.

I am missing a point:
Istvan said When I plug in the 13.8V PS the radio shows 13.8V for only 1 second and drops to 10.4V.
Don replied so the fact that the KX3 shows 0.3 to 0.4 volts lower than the external supply is normal.

Istvan said When batteries removed the voltage shown on display 13.8V.

I don't have a KX3, but I understand the diode issue..and it makes sense...but a drop from 13.8 to 10.4 doesn't seem right to me.

I believe that means that there is no RS-232 connection between the K3S 
and P3.? Check the K3S manual for the correct hookup.

It turns out there are TWO ways you can get a 4 letter call for a
shipboard station-
You can have a licensed radiotelegraph station, OR
you can have small boats with permanent radio installations.
In 2014/5 I got OLIVER HAZARD PERRY the callsign KOHZ by citing that rule when
we did our original application, and installed radios in our small boats.

And as lagniappe, when BOUNTY was foundering in late October of 2012,
the master was licensed as KD4OHZ, and we used the Winlink station on board
with his callsign to communicate with the USCG by email.
I've always wondered if the former callsign was related to the latter. since
both boats were in the same category as sailing school vessels, and someone
at the FCC picked up on that.  But probably not.

Hi Doug,

If someone wants to translate the built-in manual into another language, we'll definitely make it accessible. In that case we would have to share the source material with them. It's authored as a Google doc so this is easy to do.

I kind of like that the K4 has a built in manual, which is no doubt 
updated as required AUTOMATICALLY.

Is there a provision to print out the manual from the K4?? I'm pretty 
much a "paper person" and print out all my manuals. Not having to 
revisit the Elecraft web to see if a more recent version of a manual is 
available would be a? nice bonus IMHO.

Even if you could do that, it might not be as useful as you expect.  Sections/topics are linked from a main page and keywords, but not paginated.  And there?s no page numbered ?index? to help you get around.  This is more of a greatly expanded ?help" function than a typically organized manual.  It would be hard to get around in it on paper, unless you did a lot of reformatting and/or indexing before printing it.

Just one though on the subject.

There's been quite a bit from Wayne on this reflector, and updates in 
their monthly update. You may have heard that there's a pandemic, and 
the west coast has been experiencing massive wildfires. Both of these 
disasters have caused huge disruption of our lives, businesses, the 
supply chain for every imaginable product. My neighbor K6XX, a 
manufacturing engineer at Elecraft, lost the superstation he had built 
from scratch on 80 acres he had cleared himself. That same fire burned 
out three other neighbor hams, and stopped at the edge of the road 
bordering our land.

I recommend checking the P3 Manual for the correct hookup.  You can either
use the optional CBLP3Y cable (a separate purchase) or the RJ-45 to DE9-F
adapter cable that is supplied with every K3S.  If using the latter, you
have to change CONFIG:RS232 to 38400 (not USB), and the USB cable can
only be used for the USB Audio CODEC, not rig control, and you use the same
serial cable you were using before, with the K3.  Otherwise, you need to
use the CBL3P3Y to make everything work with one USB cable (CONFIG:RS232
USB).

Interesting.  There is currently no vessel of that name nor record of a vessel with callsign KOHZ in the ITU maritime callsign database.

I just downloaded the schematic from the Elecraft site. I think this style of schematic, while space-saving, is difficult to read.
On p 9 @ B5, please find J1.
9-15VDC.
There you will see D6. I was expecting a different circuit, one that fed BAT+ and 15V+ each through a diode. That would provide a diode drop for each device, and provide reverse polarity protection.

If you are supplying 13.8V, the KX3 should report about 0.3-0.4V less. These are likely low forward drop diodes.

Even so, I am guessing that this is the correct place to look. Your problem suggests that if the voltage drops when good batteries are inserted, and pops back to 13.8Vdc when they are disconnected, then the problem might be in the charging logic. Some device may be making active choices for when to charge and when not to, and how much.

More than that is out of my league...

Message-ID: <6D69A2A0-E921-4B78-BAC4-08CA8BE90557@me.com>

I operated over the weekend as W6E as one half of a M/M HP County Expedition in CQP.

I ran the SSB side of the show and N6MI the CW. Scott has the FTDX101.

We were both operating 500w into similar spec-ed 2 element beams on 20/15/10. We were about 300-500 ft apart.

I?m looking for advice on how to minimize the CW thump thump I would hear when we were both on the same band. It didn?t raise a HI SIG warning on the K3s but it was audible enough to distract me especial if an adjacent station was bleeding into my band.

Maybe the solution is a K3s setting, maybe filters (tough) or better separation.

Using 2.48 here and no issues ragchewing on 80 meters or doing digital
FT8/FT4 on several different bands. I have the XCVR port connected to the
USB port of a Flex 6700 via the KXUSB cable.

It cost more to ship the shipping box to you for shipping your radio back to Elecraft than the shipping box cost.  Worth it!

Hey Alan

My heart goes out to you as your circumstances seem unimaginable to me.

I think 2020 is a year not many of us want to remember and generally if we do not too much of it's positive.

Your humor is admirable and should help all round including the un-male thing of having to do intensive clothes shopping.

#1) Buy Scott a better radio. Yaesu radios are notorious for being a 
very bad neighbor. They're dirty, there's nothing another radio can do 
when the other radio is spewing trash on your frequency.

#2) Study my talk on multi-station interference for many things you can 
do with station building, antenna choice, feedline choice, antenna 
layout,and the use of serious ferrite chokes at every antenna feedpoint.

Also see my detailed analysis of ARRL Lab tests of a selected number of 
rigs. The raw data for my report came straight from ARRL Labs in 
electronic form. Also see ARRL Lab plots of keying bandwidth and phase 
noise for Scott's radio.

Hi Tom,

If your current set up works well, why not just wait until the K4 is 
being delivered. Then choose.

I have the same set up as you for the past ten years. Am happy to wait 
for the call to come to me for a K4. I am in group 2.

This is not nonsense in my experience, but I am an exclusively VHF operator where bad transmitters are immediately obvious. This statement ''nobody considers them poor neighbors' is incorrect. I do! They are bloody awful!

Rob Sherwood's attempts at focusing attention on poor TX composite noise and poor IMD is admirable. I hope that he continues to raise awareness on this issue.

On 6m those using the FTDX-5000 with QRO are quite difficult to deal with. Less so now everybody is on 50.313 and most locals are on the same sequence!

One FTDX-5000 user is on 2m and 70cms EME, he uses the FTDX-5000 as a driver for his transverters. Same problem, the poor PN is extremely evident. Again, the use of the same TX sequence helps and fortunately he does not participate in VHF contests.

The other radio that is quite offensive is the IC-7300 when used with a PA. When the power is turned down the composite noise gets much worse, especially on 6m. Some people are using them to drive transverters, same problem. It is obvious because there is a major noise bump at +300kHz!

I have measurements done with an FSWP Noise analyser to back this up. There are thousands of IC7300s in use and this is one very disappointing aspect of their performance. The user is unaffected, other band users must suffer. The IC9700 is fine unless used with a big PA then these are not good neighbours. I can see the appeal of these radios but Icom need to do better!

The FTDX-101 series is MUCH better than Yaesu's previous offerings, although I only know of 2 of them locally. They are good in fact.

If you like I CAN substantiate the claims with measurements.

The K3S has excellent low PN but use it on SSB and the IMD is unacceptable, I am VERY disappointed with my K3S TX IMD on 6m. Good job nobody uses SSB on 6m these days ? This is an extremely unpopular opinion on this forum and I really hope that the K4 is better!

It is extremely difficult to convince the owner of a shiny new radio that his signal is bad, it MUST be the receiver. Even though receivers are getting better and better.

I had exactly the same symptons as the OP just a couple of weeks ago and it puzzled me too. With my KX3, the "cure" for this behaviour was to change the display settings from external voltage to internal voltage. I think that the radio displays a default reading first and then changes during its boot up procedure dependent upon how you have it configured?

Apologies if I'm off target here- I've just endured an hour and a half trying to work out how to post a reply and I'm still not sure! My bad I guess?

Message-ID: <CAG4eVbWQ2_O5JLzq1mGw3adUjuQEqrRPANdaZrPE-0be6oOTLQ@mail.gmail.com>

Just as a reference. Over the years I've sent equipment to Yaesu USA for
repair. I sent them in the original sales box surrounded by a form-fitting
shipping box as I received it from the dealer. When I received it back both
boxes were within a new form-fitting box so I ended up with the equivalent
of a 3 wall thickness box.

It would be nice if Elecraft and others could do the same plus send back
equipment with new custom foam and in custom boxes (if they don't already)
if received without them. However, I do believe Yaesu did charge for the
overpacking. I don't recall if it was an option but I believe they may have
warned you of that fact and practice before you sent it in. I, for one,
welcome the safe practice to protect my equipment.

Of course, Yaesu and others build their higher end radios with a larger and
much heavier cast aluminum chassis which makes custom foam and boxes more
critical.

Yes. But the packing is a bit expensive. And, you get a free radio in every box.  

I take it you didn?t save the one they sent it in.  Or you bought a pre-loved item

In my case, I would need to disassemble my KX3 and put it all back in the individual kit subboxes.
I never had a box that holds an assembled KX3. Same thing for the PX3 and KXPA100. :-)

ARRL Lab engineers are not active in contesting, hence are unlikely to 
see these problems. My "paper" you referenced is a re-plotting of ARRL 
Lab data for all rigs on the same scale, and at scales large enough to 
clearly see differences. It is THEIR DATA, not mine.

Not a problem? Yaesu rigs used to be pretty clean on SSB; current 
vintage Yaesu rigs are VERY dirty on SSB, occupying three times the 
bandwidth of a clean SSB signal. W4TV, a retired broadcast engineer, 
traced the cause down to their method of doing ALC. I became aware of 
this when trying to work next to one of these dirty stations on the 
band; the P3SVGA display clearly showed the IMD-caused splatter on both 
sides of the station's intended signal. The splatter extended more than 
2 kHz below his USB suppressed carrier frequency, and almost than 5 kHz 
above it. A clean SSB signal (not ESSB) signal is about 2.7 kHz wide.

After this first experience, I observed a lot of signals like this, and 
asked some of them what rig they were using. It was nearly always a 
Yaesu. Those that were not were splattering because they were 
overdriving their amp.

This is NOT parochialism, it's solid engineering, which is my expertise. 
What's yours?

Message-ID: <792af8a8-8411-361b-d689-f79c512c90e6@shaw.ca>

Here's my issue and it has just begun.
I'm using a Heil Proset with my K3s, when I switch to VOX the tx LED 
lights with no input.
With the headset on my head, if I touch the K3 case the LED goes out and 
I am able to tx while holding the case.
With the headset resting on my desk near the K3 the LED in not lit, but 
if I touch the headset the LED lights.
With the mic jack unplugged the LED does not light.
I've examined all jacks and lines
Seems like some sort of capacitance issue maybe.
Any help would be appreciated.
Thanks

Every time I see one of those plots from the ARRL Lab, I wonder ?what is a good number?? I really wish they would add some additional lines to the graph. One suggestion:

* FCC regulated limits (where they exist)
* 90th percentile (best 10%) of tests in the previous five years
* Best test in the previous five years

I think those would be a nice contribution towards the "Continuation and extension of the amateur's proven ability to contribute to the advancement of the radio art?, to quote Part 97.

I guess I should be telling this to QST and the ARRL Lab, not this list, but does this sound like a good idea to others?

Maybe Elecraft can publish these for the K4 to get the ball rolling.

Several years ago I purchased shipping boxes for Collins S-Line radios from a source I believe was called "Ham Radio Boxes" .  I don't know if they are still around or not, but the boxes were exactly what I needed.

The problem for most of us is storing the boxes. The solution I've 
adopted is to break down the boxes I want to keep by slicing the tape 
holding them together, then folding them flat for storage.

Subject: [Elecraft] KAT500 remote
Message-ID: <30e90fdc-de6a-d63d-b502-0e98fcec14c0@gmail.com>

I use the KAT500 remote software and it works great. I have only one 
problem with it, I can not tell if the power is on or off. This matters 
because when the remote site looses power the state of the KAT500 is 
unknown and the program does not indicate if the power is ON or OFF.? Is 
there a way to tell?

I can keep trying the POWER button then the TUNE button until it works, 
but it would be much better for a positive indication of the power state 
by button color or some other indication in the application.

I have set the "Initial Power" in the KAT500 utility to be "Power On" 
when DC? is applied, but not sure this is always observed.? I have no 
other way to see the remote site when this happens.

Any suggestions?

You may want to check with Lulu.com

They may print you 1 copy for your use, which is allowed under US copyright law?. For an extra charge of course.  I believe the procedure would be purchase the pdf, download it, the submit it through their web site tool for on demand printing?

 I was looking for the last version of the Cady K3S P3 book and purchased the pdf, but the found a printed copy, which I purchased.  I want a macro-programming book also, and may try what I have outlined above.

Some of that information is in my summary of ARRL Lab tests.

FCC limits are not expressed well for those who deal only with numbers. 
What SHOULD be the dominant paragraph says that the bandwidth of a 
signal shall be the minimum required for the means of transmission. In 
practical terms, that means carefully shaped CW keying, minimum phase 
noise, minimum IMD. It's essentially a "state of the art" spec. But 
because there are no numbers attached, the paragraph is widely ignored.

I did a search for the ability of the K4 to display DX spots on screen, and
the ability to "click" on them to QSY to the spot, interfacing with 3rd
party programs like DXLab or N1MM+ (assuming they can and do develop that
capability). 

I found Rich's question (see below), but couldn't determine if there had
been any answers.

What say you Wayne and/or Eric?

How is your Heil headset connected to the K3S?  Mic jack using the
Heil AD1K adapter or directly to the rear panel (3.5mm) mic jack?

Heil are *notorious* for incorrectly wiring their adapters
(mic ground and PTT ground reversed and/or mic ground connected
to the shell of the Foster plug).  If you have the AD1K adapter,
check it carefully!  Also, make sure you are not using the
extra high gain preamp - the Heil dynamic mics have enough drive
to work with RP.H/FP.H settings (the + is not needed and BIAS should
be OFF).  Heil's iC (electret) element works with RP.L/FP.L BIAS.

I can't claim credit for that ... the information was originally
identified by W8JI in Yaesu rigs as far back as the FT1000D and
FT1000MP (and other Yaesu transceivers of that era).

Not only do Yaesu derive their ALC based on overdrive of the final
amplifiers, they have excess gain in both their TX IF and ALC loop
which only makes matters worse (as anyone who is familiar with the
design of servo control circuits will understand).  One can make a
noticeable improvement in TX IMD in Yaesu transceivers by reducing
the TX IF gain (if one knows how to access the factory alignment
menu) on each band to the minimum necessary to reach full output.
Reducing the IF gain also reduces "overshoot" and helps with the
key clicks but - alas - it does nothing about the phase noise
issues.

Dude....? just print it yourself on your chosen paper stock.? You can 
spiral bind it yourself at OfficeMax, et al.? OR you can send it off and 
have it bound.
Or just punch holes and put it in a folder or a notebook.

I have a FULL set of the latest Elecraft docs, et al. including ALL my 
Cady books printed and in notebooks for flat, easy reference.

Practice on a small, multi-page doc to get your printer settings 
optimized....? I print best quality, two-sided, standard paper... Works 
great!

Clay,
When I was traveling, we would send the document (PDF) to the local Kinko
which is now FEDEX.
They would print the document, make a cover and back page and then
spiral bound it.
Generally it was 10 to 25 copies depending on the group we were presenting
it to.
We found this easier than ordering through our print shop and then
carrying 25 copies of a 25 to 50 page document on a plane.
Might try a local equivalent to Kinko (FEDEX).

You could possibly look at Node Red which runs on a Raspberry Pi. I use it with a KPA1500 and I know there is a flow (programming) for the KPA500 as well. The Pi runs on your home network and you use a USB to serial cable from the KPA500 to the Pi. You can control and monitor the amp from any web browser.

If you are interested we have a Google Groups.io site https://groups.io/g/nodered-hamradio

Here's a picture of my Node Red dashboard. The panel on the left is for the KPA1500. The layout is customizable.

Subject: [Elecraft] KAT500 remote

I use the KAT500 remote software and it works great. I have only one problem with it, I can not tell if the power is on or off. This matters because when the remote site looses power the state of the KAT500 is unknown and the program does not indicate if the power is ON or OFF.  Is there a way to tell?

I can keep trying the POWER button then the TUNE button until it works, but it would be much better for a positive indication of the power state by button color or some other indication in the application.

I have set the "Initial Power" in the KAT500 utility to be "Power On" 
when DC  is applied, but not sure this is always observed.  I have no other way to see the remote site when this happens.

Any suggestions?

Subject: [Elecraft] K4 Update Oct 9
Message-ID: <CAGe0YDaONiosP707CpGPJr_7vLk+2bVemLchjJyqoEeaWF73pQ@mail.gmail.com>

To answer the big question, yes we started shipping small numbers of our
first regular production K4s in late September. :-)   We are building more
K4s now in production and we expect more to start going out late next week
or the following week.

Our production rate will be slower than we want through the rest of October
and early November as we fine tune everything
and navigate intermittent supplier delays, temporary production stoppages
etc. and as we continue to tune our production and test processes. As the
K4 production rate gets stabilized we will also be able to give better
estimates when individual orders will ship. Please be patient with us as we
work through this.

One note - initial K4 orders on 5/17 were huge, both on the Web and at
Dayton. (As were ordered the following weeks and months..) Even the first
shipping group K4 orders with large deposits from that first day were so
large that they will take some time to ship. We will email or call to
notify everyone as their order gets close.

It's been a challenge dodging all of the unexpected obstacles we've
encountered the last several months. COVID-19 shutdowns, the CA Fires and
the resulting impacts on our staff, suppliers and overall efficiency have
been challenging.  Many of our team are working from home due to COVID-19
requirements (including Wayne and myself, engineering and most of our sales
staff). The CA fires had a major impact in late August and through
September. Two of our engineers lost their homes and radios, and a third
came close, with the fire coming within a mile of his location. Fortunately
everyone is OK and back at work and there is no ongoing fire threat
locally.

The Elecrft HQ and factory in Watsonville is far from where the active
fires were and was never at risk. It's in an open industrial park far from
the forests and near the coast. We have also reconfigured the factory and
test area layouts for safe operation with regard to proper social
distancing, better air flow and good workstation isolation between workers.
Our inventory is safe and our production and test teams are hard at
work there.

Several of our local suppliers (machine shops etc.) had mandatory
evacuations for several weeks as a precaution during the local fires.
Fortunately their facilities were undamaged, but that has increased delays
getting parts finished and delivered to us as they restart.  Each day
presents new challenges. So far, we've been able to work through each
new surprise.

We are in good financial shape, with plenty of funds to run our operation
and fund the K4 ramp up. Amazingly, even during the COVID shut downs in the
spring we continued to receive orders for all of our products at a strong
rate. It looks like the extra time everyone had while staying at home has
increased interest in ham radio! As a result we are still running with a
strong backlog of orders for our regular products, which are shipping daily
in addition to the K4. This has helped enormously.

Thank you to everyone for your support.

73,
Eric

Sorry - cut/paste error - should be:

If a KAT500 is powered but off it will respond to command ps; with PS0;
If a KAT500 is powered and on it will respond to command ps; with PS1;
If a KAT500 is not powered it will not respond to ps;

A neighbor who lives just 300 yards away purchased and now operates an
IC-7300.  When he operates 40m CW, the phase noise occurs across the entire
40m band on my K3 with the upgraded synthesizer.  You could never use an
IC-7300 for Field Day on the same band with other radios.

OTOH, we had three K3's (prior to the upgraded synthesizer on 20m
simultaneously.  We only knew the others were active if we tuned to within
20 kHz or so of them.  I was the the SSB team captain and had no problem on
20m as long as we didn't get "near" the GOTA station when it was on the same
band.  This was with the same physical distance I know face the IC-7300.  

Another IC-7300 over a mile away is very broad (20-30 kHz) when operated on
40m SSB.  I often hear splatter 40 kHz up the band!  While I tell people the
IC-7300 is a great package for the price, I also tell them not to use it
with big antennas or physically near other radios.  Fortunately, I have no
Yaesu HF rigs in active use in the neighborhood although I see their dirty
signals in many contests.

A used K3S is quite a bargain today!

It doesn't display spots today. It could in the future.
It does support click-to-QSY with either a finger on the screen or a mouse
(more accurate pointing).

Hi Andy,

Someone on anothergroup mentioned sending P; to the KPA500 would turn the amp on provided to main power switch was on. Can you confirm that?

Reason is I want to make sure the Node Red flow I had mentioned is programmed correctly.

I use Wake on Lan with the KPA1500 successfully.

Thanks

	"ARRL Lab engineers are not active in contesting,..."


Meh.  Suggesting the ARRL Lab is ignorant about real world contesting is incredible.  They are plenty smart, have their own stations, and do NOT live in a technological vacuum.  If it was a problem, they would know it.



	"It is THEIR DATA, not mine."


Exactly.  You concede my point.  You present no evidence or proof of your own, and concede the available data fails to prove the problem.


	"Yaesu rigs used to be pretty clean on SSB;
	current vintage Yaesu rigs are VERY dirty ...
	occupying three times the bandwidth of a clean
	SSB signal"


Pshaw.  You exaggerate.  Three times normal bandwidth is more than 8.5 MHz.  If ALL Yaesu signals really are that wide, everyone would know it, and even the least expensive SDR dongle would easily show it.  The boys in the ARRL Lab would be well aware of it, and besides, it makes no sense to say "current vintage" - as "current"  and "vintage" are essentially opposites.


Bottom line:  I gave you the home run pitch, challenging you to proffer hard evidence of your unsubstantiated, anecdotal claim. Instead, your generalizing rebuttal and brandishing credentials is weak as water.


AS for MY experience, while I am not an engineer, I am reasonably well informed and made my millions cross-examining self-proclaimed experts lacking sufficient evidence.

As this is clearly OT, I will retire before wearing out my welcome, especially considering you have made my point for me!

Happy days, and good DX to all.   K8JHR

 ??? Thanks, but I'm not using software I wrote.? I'm using the remote 
software from Elecraft, and that is the software I'm talking about not 
seeing if the power is on or off.?? I was hoping that I was just missing

Good day,

There have been a few requests for help with "problems" recently to 
which the group has freely applied its hive mind and made suggestions.

Unfortunately this often results in a deathly silence as to the 
resolution. Clearly this could be a learning point for others who might 
trip over the same problem one day, even if it was just finger trouble 
or a brain fart. Assuming they read the posts.

Whatever, most discourteous.

"Someone on another group mentioned sending P; to the KPA500 would turn the amp on provided to main power switch was on. Can you confirm that?"

The power on command is P  not P;

>From the programmer's reference -

"BootLoader Command Reference
The KPA500 uses single character commands when in boot mode. Boot mode is the state the KPA500 is
in when the rear panel power switch is in the ON position, while the main firmware is not running. This
mode is used for starting up the KPA500 or downloading fresh firmware. Bootloader commands must be
sent upper-case only.

P Power On
The P command will cause the KPA500 to perform internal firmware checks, then execute the main
firmware to power up the amplifier. This is the command to use to remotely power up the KPA500. No
response is sent from the KPA500 after receiving this command."

Hi Mike.

Well, it was still looking like in AM mode so I reached out to Elecraft 
Support. They have suggested a test to run and send the results back to 
them. Now I can not reproduce the error.

Hi Mike.

No joy. Seemed to still be in AM mode with DATA displayed. So I reached 
out to Elecraft Support with result of a test to run and send them the 
results. But now I can not reproduce the error.

Hi Mike,

In my case takes me time to do the suggested tests. Late yesterday I 
could not reproduce the problem. Sorry I did not reply to the group with 
the resolution. My K3 now does not seem to be switching in to AM around 
5 MHz when I have the mode set to DATA. I have some tests to do if I can 
reproduce the error.

have in finding places to live that allowed antennas. He thought it would
be a great idea to start up a development just for hams, so there would be
no restrictions in the deeds against antennas. I had to tell him that the
last person I want living next door to me is another ham. Which of course
led to another discussion.

Subject: [Elecraft] KPA500 REMOTE POWER CONTROL
Message-ID: <1958184661.126635.1602340493005@connect.xfinity.com>

HI Gordon-- I run a KPA 500 remotely and have the same problem some times. But there's a big green bar at the bottom of the utility that sez "power on". That should be your first indication. But its hard to know what's going on at the remote site. I use a 'remote rig' setup to run the radio and the COM1 port to talk to the KPA 500 and for power on and off I use a set of contacts from a microbit webswitch to toggle a short across pin 12 on the ACC plug on the back of the KPA --and that's the same as pushing the power button. The webswitch is very reliable and I use if for other stuff like switching a fan in the transceiver box, KAT500 power and a couple of coax relays. Here's a webpage with some of the info: http://www.valhallatreefarm.com/WB7ELY/kpa500/kpa500.htm

Subject: [Elecraft] KX3 FW - N0UK tx inhibit & CW sidetone bug reproduced
In-Reply-To: <mailman.12093.1600204158.3115.elecraft@mailman.qth.net>
References: <mailman.12093.1600204158.3115.elecraft@mailman.qth.net>

I was able to reproduce the bug Chris, N0UK, reported with tx inhibit
and CW sidetone on the KX3.

To be thorough, the FW as just installed by Elecraft, is uC 02.90
anddsp 01.52which is the latest.

I have cabling for the ACC2 port, as I use ring contact to PTT a
transverter and also to PTT a KXPA100.

Menus have had minimal configuration post service from elecraft, just
enough to setup for transverter operation in the 10 GHz contest.  Mode
is CW and VOX is on of course.

ACC2 Inhibit = Low.  I used a paddle on the KXPD paddle port (key 2).
Was able to get the stuck sidetone as you describe while sending dits
or sending dahs by.  (Key 2 left = dot.)  For kicks, changed to Key 2
= hand.  Found that if the key is released before inhibit is released,
the sidetone does not stick.  The value of inhibit when the key is
initially asserted is not buggy. Saw the same behavior with menu
setting inhibit high.

inhibit low
key - inhibit - inhibit release - key release --> sidetone stuck
key - inhibit - key release - inhibit release --> sidetone OK
inhibit - key - inhibit release - key release --> sidetone stuck
inhibit - key - key release - inhibit release --> sidetone OK

inhibit high
key - inhibit - inhibit release - key release --> sidetone stuck
key - inhibit - key release - inhibit release --> sidetone OK
inhibit - key - inhibit release - key release --> sidetone stuck
inhibit - key - key release - inhibit release --> sidetone OK

The behavior is a problem is in the firmware at the inhibit released event.

A thorough bug report would also include observations of the PTT
output and actual RF output.

Best regards,

Drew

That is the key step.  With ?Initial Power set to Power On? when DC is applied, the KAT500 will indeed always be on when power is applied.  The question is what happens if power is removed and recognizing that the KAT500 is without power.  

The Elecraft Utility tests for a Com Port connection when it opens.  If the KAT500 is not on, the utility will not see the KAT500?s com port and it will be unable to connect.  If the KAT500 is on, the connection to the PC will established (assuming your RS232 cable is connected to a PC).  You can see the results in one of two ways:

1.  Under the Port Tab, selecting that and you?ll see a box open reporting the connection and the serial speed of that connection, or

2.  Under the Firmware Tab, there is an activity log that shows the sequence of events to open the Com Port and establish a connection.

If the KAT500 does not have power, these tests will fail.  Under the Firmware->Activity Log you?ll see entries stating (for example):

10:56:02 Attempting to contact KAT500 on port COM2 at 38400 bit/s

as it scrolls through different baud rates attempting to connect.  If you see this, the KAT500 is not getting power.

Presumably you have a way to remotely turn on the power supply connection to the KAT500. When power is restored you?ll see confirmation in the activity log:

10:59:39 KAT500 version 01.75. Serial port speed 38400 bit/s


I use a West Mountain Radio R40051 which is a web-based device that has five power ports (Anderson Power Poles) where one provides power to the K3, a second port provides power to the KAT500, a third port provides power to the Remote Rig, and a fourth port provides power to the Antenna Genius 8x2.  Thus, I can shutdown/recycle these devices remotely. I shutdown the equipment when severe storms are expected, or it appears that there may be a glitch that a reboot might resolve.  Given that I?m currently 1,280 miles from the shack, redundancy in the form of being able to power down/power up equipment is a nice feature.

I can also remotely shutdown and restart the power supply that powers my Elecraft equipment  (except the KPA500 which is on 240VAC) by using an AC-PWR module from WMR that allows the R40051 to power on/off the power supply through a different port on the same R40051.  I use a 3A power supply to power the R4005i (it is always on) and second 30A power supply to power the K3-KAT500-Remote Rig-Antenna Genius.  

The KPA500 is controlled separately through a Remote Rig RC-1216H that provides a web-based screen mimicking the KPA500 front panel where I can power on/off and set standby/operate through the interface as well as see the LED meters,  As I use Remote Rig with the K3, the K3/0-mini activates the K3 when the Mini is powered on.  I also use a second RC-1216H to control my Green Heron rotor controller.

BTW, I did a copy/paste of the Activity Log remotely to provide this information to you  as I use a PC in the shack to control the KAT500 and connect via VNC Client from my MacBook Pro.  I accessed the R4005i directly through a web browser to be able to turn on/off the KAT500 with a MacBook Pro.  Thus, I don?t need a PC at my location to control my station as I can use an iPhone or iPad to do it as well.  The station is in Southeast Georgia and I?m currently in Rosllndale (Boston), MA.

Hope this helps,

Barry, WD4ASW/1

Andy,
 ?? Thanks, but I'm trying to use KAT500-Remote Version 1.0.15.0 from 
the Elecraft Web site, under "Logging, Control and Remote Software for 
K-Line & KX-Line". This? allows for hosting a KAT500 over the internet 
for control by multiple clients.? The actual commands sent to the tuner 
are hidden by the software.
Thanks,
Gordon - N1MGO

Barry,
 ???? Thanks for the comments and hints.? I'm using the KAT500-Remote 
Version 1.0.15.0 software over the internet to a remote system in a 
different town.
This is NOT the utility software, it allows for hosting a KAT500 over 
the internet for control by multiple clients,? a different program.? The 
client end does not have a clear indication of the power status of the 
remote KAT500.
Thanks,

I can?t help you with the KAT500-Remote Software because I don?t use it.  If you?re not satisfied with how KAT500-Remote is working for you, then I suggest taking a look at the KAT500 Utility software (v.1.19.18.5).  As I explained, simply log into the ham shack computer with VNC Client, TeamViewer, etc.  to manage the KAT500 utility and you?re good to go.  One advantage of this approach is that you don?t have to install the Elecraft software on every ?client? computer to be able to access the KAT500 and you?re not limited to a PC as other devices that can run VPN Client TeamViewer, etc.  (iPhone, iPad, Linux, Windows, Android, Google Chrome, etc.) can access the local computer running KAT500.  It also doesn't require port forwarding configuration to gain access to the shack?s PC.

Another approach with the KAT500 Utility is to use a Lantronix EDS4100 (or similar) Serial-to-Ethernet Device Server which provides a ComPort connection between a device (such as the KAT500) and the PC where you?re located.  Connect the KAT500 RS232 port to an open port on the Device Server, install the Lantronix ComPort software on the PC of interest, configure the EDS Device Server with the RS232 settings needed, and now you can connect directly to the KAT500 using the Elecraft Utility Software from wherever you are.  The Lantronix ComPort software configures the PC to accept an ethernet connection and convert the connection to reflect a ComPort.  Windows Manager sees it as a ComPort, and you specify that ComPort in the KAT500 setup (I used Com9 set to 38400 baud).  You?ll will need to setup port forwarding at the hamshack to gain access to the Lantronix brower-based configuration setup and/or run the Lantroix utility software to manage the Device Server.  You can install the Lantronix ComPort software on multiple PCs and they can all access a given ComPort (one connection at a time) for the KAT500. 

I've used the EDS4100 for a number of years to access my KAT500 remotely using the Elecraft Utility running on Win10 on my MacBook Pro running Parallels to create a Win10 Virtual Machine.  I also installed it on the shack PC.   I also used the EDS4100 (which can support four physical ComPort connections) with my KPA500 before I switched to the Remote Rig RC-1216H.   Again, that change was done so that I  could access the KPA500 with a web browser.

In summary if it turns out that you?re not satisfied with your current approach, I heartily recommend using the KAT500 Utility software to manage the KAT500 as I?ve outlined.  You'll have access to the same front panel controls as you would sitting in front of the Tuner:  Power, Tune, Memorize, Mode (Automatic, Manual, Bypass), Antenna (1-2-3).  You?ll also have   ?Other? options (Caps on Ant Side, Bypassed, Attenuator, Amp Key Interrupt) and the software  shows you the "Last Observed? Frequency, VFWD, VRFL, SWR, ByPass SWR, Band, and Tune State. It also displays the capacitance (pF) and Inductance (nH) of the tuned ?solution?.

I'm putting my K3 (Serial# 6384) up for sale.  Do not reply to the list, I
will only reply to direct emails if you convince me you are serious and
then we set up time to talk on the phone (any cc'd reply / email to a
reflector will not receive a response).  I might consider shipping outside
of the US depending on the right offer etc... but would prefer shipping to
the CONUS. I can't find any cosmetic issues except for a couple of tiny,
tiny scuffs on the bottom.  I will NOT 'part' this K3 out at this point, so
DO NOT ask. I have other Elecraft 8 pole filters from another K3S I might
part with based on a real discussion on the phone and a real offer you are
making.  Based on my research (which I can't find an exact comparable), I'm
seeing a price that would be more than $2000 and less than $3000. So yeah,
I want to get serious offers when we have a phone call.  I'm not desperate
to sell... so please don't waste your time or mine.  No weird machinations
on payment either... Paypal? you pay all fees etc... or bank transfer or
cashiers check, and everything clears before I ship as one would expect.

I will ship the K3 in an Elecrdaft K3 shipping box

I'm the original owner and for the last 4-5 years this K3 has rarely been
used, stored in a pelican case... only operated for a few remote outings.
I live in Utah, which is a super dry / low humidity climate / no smoking.
The SS screw / hardware kit, which is installed will show some screws that
are not solid black, this is normal for the SS hardware kit.  I usually
operate with an external amplifier so the high power amp in the K3 has
rarely been used at 100% output.

Pictures as of Oct 10th 2020, more can be provided if I determine you are
serious... internal etc..

Good Evening,

 ?? It was a good week to sleep with the windows open.? Cool breeze, 
some rain, and a few owls.? One night it was a single Saw Whet owl 
filing away for hours.? The next night started with two owls making 
generic owl noises.? Then one of them broke into the familiar Barred Owl 
call.? They kept this up until I fell asleep. Luckily the loggers are 
back, but this time of year they arrive especially early: around 4 AM.? 
This company leaves no slash behind.? And you wondered where chip board 
came from.

 ?? The sun has two sunspots which pose no threats of solar flares.? 
Seems so ominous when that's what we desire.? Strange. The solar flux 
index is a bit higher.? The sun will be a bit lower this week for the 
second net.? That means after dark for folks east of the Rockies.? Here 
the sun will be filtering through the canopy.? But with the weather the 
way it is I'll probably not see it for the clouds.? Fire danger has 
dropped another notch, which is comforting.? Hopefully, this weather 
system is bringing rain to Northern California too.? They could really 
use a few inches right now.

Please join us on (or near):

 ?7047 kHz at 0045z Monday (5:45 PM PDT Sunday)

I have an application where I would use 3 RX antennas. Two could use the
RX1 and RX2 ports but the third would use one of the ports provided by the
KAT4.

My concern is avoiding accidentally transmitting thru that third RX port.
Will the ANT CFG constraint of the TX antenna to ANT1 ensure that?

Don,

I finally got around to running my K3 into a dummy load.

I had no problem running 100w or even 110w with a dummy load. Current draw from the power supply was 22 A and 23 A, respectively, on the K3 display. No HI CUR indications.

External wattmeter validates the output.

I was getting the HI CUR indication on a trap 30/17/12m inverted V. I had to take it down, and now I?m using a trap 80/40/20m dipole through the tuner. No HI CUR indication on that antenna, either.

Even though I have current baluns on both antennas, I?m thinking that my HI CUR problem may be related to RF feedback in the shack. 

Do you concur?

I?m in the process of a number of shack improvements, including antenna replacements and grounding and bonding, so that might take care of it.

If this has already been announced here, forgive me; when life is busy as it has been over the last couple of weeks I don't always read the reflector.  In any case the news is worth repeating.

In the October issue of QST, at p. 62, the ARRL announced that Jim Brown, K9YC, a frequent contributor to this reflector, was awarded the ARRL's Technical Service Award for 2020, recognizing his numerous contributions to Amateur Radio in numerous venues.  I won't repeat the encomium here; just wanted to share my congrats to Jim.

This can be easily set up. The K4 will protect the receivers, too.

Good Evening,

 ?? QSB made life interesting.? It varied from slow waves running from 
S3 to S9 followed by faster rates as I copied farther west. By the time 
I landed in CO or TX the rate began chopping characters.? I had to ask 
W0LI for many repetitions.? Each element was being broken into dits.? 
First I copied the trailing LI but kept hearing VE9 or JA1 for the 
prefix.? Finally the W0 portion popped out.? Thanks for the patience Dick.

 ?? One weather report stuck out: Roy's 82F and sunny.? Makes me want 
beach front property in Iowa.? Then sanity breaks my bubble when I 
remember the biting insects.? It is easy to make a blood donation there, 
just walk outside on a humid summer night.? Dave was working on his deck 
while Ken had been evacuated from church because of a power outage.? It 
is wet in the SE and in the PNW. If only I could ship the excess to 
where it is needed.


 ? On 14050.5 kHz at 2200z:

W0CZ - Ken - ND

K6XK - Roy - IA

K4TO - Dave - KY

K4JPN - Steve - GA

W0LI - Dick - CO

 ??? I finished the second net with visions of barbequed chicken, 
salmon, and shrimp.? Too bad I had none of them.? So I settled for an 
inch and a half thick steak with rice and beans.? Too bad Oregon is so 
far from Maine, the lobster is rather pricey here. They go well on a

Bill,

I would suggest that you check the SWR on the antenna before concluding 
it is an RF feedback problem.
Don't forget that the balun may be breaking down with power and show no 
problem at lower power (like from an antenna analyzer).

If this has already been announced here, forgive me; when life is busy as it
has been over the last couple of weeks I don't always read the reflector.
In any case the news is worth repeating.

In the October issue of QST, at p. 62, the ARRL announced that Jim Brown,
K9YC, a frequent contributor to this reflector, was awarded the ARRL's
Technical Service Award for 2020, recognizing his numerous contributions to
Amateur Radio in numerous venues.  I won't repeat the encomium here; just
wanted to share my congrats to Jim.

I just watched this and appreciated hearing about the company's early and developmental history. I bought K2/10  #1034 in early 2000 and built it over 4 long evenings. I still have it, along with both KX radios.

For Sale: KXPD3 ? KX3 Keyer Paddle Assembly

First $100 (plus $10 for shipping) takes it.

I bought an external key to use with the KX3, this one is just collecting dust in the shack. I have used it twice, but really prefer an external key on the desk. Bought direct from Elecraft less than 2 months ago.

Thought I would try here first before I post it on FleaBay.

Richard,

I don't know the answer, but when you get receiver sensitivities better 
the -135dBm, the exact sensitivity numbers do not mean much unless you 
have an extremely quiet location.
In general, the local noise will mask anything lower than -135dBm.
I expect all K4s models to have better then -135dBm sensitivity.

73,
Don W3FPR

That may be true for the lower HF bands.  However, on 6 meters or when
using the K4 as an IF for VHF transverters and/or EME the noise level
will be as much as 20 dB less than -135 dBm.  That may even be true
with directional antennas above 20 MHz at suburban locations.

SWR on the problem antenna is below 1.2:1. It?s a trap dipole - designed for that band.

It is unlikely the balun is ?breaking down?. It?s a current balun - #43 ferrite beads on RG-313 coax. It can easily handle a kW or more.

But remember, there are two basic loading conditions that will give a SWR
of 1.2:1  ...

60R+J0 will give 1.2:1 and pull a current lower than a perfect match ...

42R+J0 will give 1.2:1 and pull a current greater than a perfect match ...

(and of course all the reactive permutations around the load circle) ...

That's a common mode choke, and #43 is a terrible material for the HF 
bands. See my "cookbook" at k9yc.com/publish.htm as well as the Ham's 
RFI tutorial, which explains things conceptually.

"handle a kW," perhaps, but only because it's also unlikely to be doing 
anything useful. :)

KPA500 AUX Pin 12 is GND.  AUX Pin 8 is the KPA500 remote power ON/OFF
pin.  No webswitch is necessary to remotely power the KPA500 on and off,
since this can be done quite easily from a button on the K3 itself, using a
macro, as described here:

Message-ID: <1602575693850-0.post@n2.nabble.com>

Hi,

i found this very interesting article by Hjalmar, OZ1JHM

With my Elecraft transceivers I have measured the following values:

K3: 4.97 V, 0.105 mA -> 0.52 mW, 47.3 Ohm
K2: 5.62 V, 0.670 mA -> 3.70 mW,   8.5 Ohm


It seems that the effect described by Hjalmar would also apply to my K3.

Does anyone have any insights into this? 
Is there already a modification for the K3 to increase the keyer current?

Especially with fast CW speeds and the associated short contact times, the
problem may already be known with some OM's.

In any case, Hjalmar's article is very interesting and invites to observe
the described effect.

Message-ID: <2F03CB4A-5CD6-47EC-8CA4-D1281CB65ABA@near-fest.com>

 Can anybody please tell me what are the differences between the K4-F, K4D-F and the K4HD?   I looked on the web site and I was unable to find a comparison chart or anything more than purchasing information.

I currently have a K3 with many of the options, including the sub-receiver.  I am just curious what the K4 has to offer me.  Is there some comparison chart somewhere to show what the advantages are for me to buy a newer K4?  I am sure others would like to know too.

Than again, I am not an avid DXer or rabid contester.  I have been licensed for over 50 years and my operating patterns are pretty casual.

I have an amusing story along these lines.
Coming home one night from a late date with my wife, we came upon a car stalled at a light. It was perhaps 22-2300.
I got out to see what I might do.
The car would not start. The usual clicking from the starter, usually indicating a dead battery.
Short version.
I asked the other driver to turn on the radio. It worked.
I then asked them to turn the headlamps. They worked.
After a bit of additional troubleshooting, during which I did nothing to the car, I suggested they turn on the headlamps and attempt to start the car. It started.
Arriving home, my wife promptly challenged me, saying that common practice is to turn off all electrics to preserve battery charge, and then attempt to start the car.
I told her that the battery was fine, and I opined as time passed that there was possibly too much corrosion on the terminals. When the starter circuit engaged, it didn't draw enough current to move the solenoid fully.
By turning on the headlamps, which are a large resistive load, a current path was generated through the oxidation. Then the starter was able to draw enough current to fully engage the solenoid.

Of course, this may have been a fortunate coincidence. ;-)

I, too, live in NH. We still get super cold periods, despite the general warming trend. My impression, stemming from growing up here in the 50s, and comparing to current weather, is that we are developing some unusual (for us) patterns. We have hotter summers and higher humidity, but less actual rain, resulting in the contradiction of sweltering summers accompanied by drought. Winters are milder, temperature-wise, but there is more precip over the winter months, much of it rain, and we now have longer periods of sub-0F weather...or so my heating bill seems to suggest. Ironically, we are faced with spring floods and summer droughts.

There is another alternative that I am considering that has its parallel in keyers. I am considering installing super caps. The difference is that I'd install the caps to provide an initial starter punch on those super cold days, whereas I'd install the caps on my keys to punch through oxide layers. The effect derives from the same source: the ability of the cap to provide a pulse of current in a short time.

There is a trick that someone told me about that apparently works when you know that the vehicle might not turn over fast enough and start on a below zero morning.  Turn the headlights on for several seconds to less than a minute to create a bit of heat in the battery that in turns gets the chemical reaction going.  This sometimes helps?or appears to  help.  My choice of insuring that the engine started was to remove the battery and bring it into the house and then reinstall it just before starting the engine.  Lots of extra work, but I was never late for work due to cold weather.

On the Elecraft website select products from the top menu. Then select K4. On that page there is a Models tab. That describes the differences in each model.

It's on youtube. Try a search on RSGB 2020 convention and it should be the first one that pops up. Eric's presentation begins a few minutes into the video, so click ahead about 18 minutes.

I am in the same boat as you.  My primary interest is e-commerce and public service.  The k3 works well for me.  I want to see significant improvement in receiver and sound quality.  I am waiting for the k4 to get out and be reviewed.

On the Elecraft website select products from the top menu. Then select K4. On that page there is a Models tab. That describes the differences in each model.

That may be true for the lower HF bands.  However, on 6 meters or when using the K4 as an IF for VHF transverters and/or EME the noise level will be as much as 20 dB less than -135 dBm.  That may even be true with directional antennas above 20 MHz at suburban locations.

Bob, That is a great plugnplay line of boxes you make!. Commendations to you for your inventiveness and marketing. However, I am not a 'plugnplay' ham and needed to figure out how I could wire something up myself. We talked early on in 2017 when I was first putting together my remote rig system and you had all the solutions for connecting up any combination of assorted shack necessities. But I I am not running a K3, I'm running a Kenwood TS-480 and feeding a KPA500/ KAT500. So I used a microbit webswitch to perform the shorting of pins 8+12 on the KPA to turn it on and off http://www.remoterig.com/wp/?page_id=166
The microbit 1216 is a great little box with five relays. I use the other four relays for a fan in the 'radio box' power to the KAT500 and a pair of coax relays. webswitch has not missed a beat in three years.  Some photos and hookup on my projects page: http://www.valhallatreefarm.com/WB7ELY/newprojects.htm

That should be your first indication. But its hard to know what's going on at the remote site. I use a 'remote rig' setup to run the radio and the COM1 port to talk to the KPA 500 and for power on and off I use a set of contacts from a microbit webswitch to toggle a short across pin 12 on the ACC plug on the back of the KPA --and that's the same as pushing the power button. The webswitch is very reliable and I use if for other stuff like switching a fan in the transceiver box, KAT500 power and a couple of coax relays.

This happened to me on a multi-band antenna, with SWR changing, but no 
Hi Cur warning.

I would be transmitting for months, using only 100W with no issues. I 
added in a KPA500/KAT500 combination and apart from a short test at 
400W, I continued to use it at 200W (SSB) max.
After a month or so, the SWR would change - mid QSO. A quick retune and 
I was able to continue. Over a few weeks the occurrence was more 
frequent. Using a Rig Expert analyser, no fault or bad SWR was indicated 
and I (wrongly) guessed that the 400W Guanella balun was breaking down 
at power over 100W. In the meantime I ordered a new 1KW balun made for 
that antenna, but before it arrived, during a QSO there was a 
catastrophic "occurrence" with all kinds of warnings and the SWR was off 
the scale.

A check with a multimeter indicated a dead short somewhere in the 
feedline (RG58). I also took the balun apart and found no fault. As I'd 
ordered a new balun, I decided to change it anyway. I don't have the 
power to exceed the new balun's spec, so it should last forever - RF 
wise. ;-)

Obviously I replaced the co-ax feeder - I now use Westflex 103 with much 
larger ferrites (to fit the new cable size) as a common mode choke. All 
now works as it should and shows no sign of breakdown, even at 400W (max 
legal for the UK).

The old co-ax is a different matter. With both ends disconnected (open) 
connecting one end to the analyser showed a short circuit about 15 feet 
along its length. I cut out a section either side and the remaining two 
pieces showed 'open' as they should. On visual inspection I find that 
the braid of the co-ax has migrated through the center insulation and is 
touching the inner conductor, indicating that a fair amount of heat has 
been generated. The area in question was right where the common mode 
ferrites had been fitted, although there were no tell-tale marks on the 
ferrites or the outer casing of the co-ax. It's fairly obvious that a 
high voltage node has caused an internal flashover which in turn has 
changed the characteristic which has resulted in a high current node 
which has generated the heat.

You may well be right that your balun is not faulty, but you should 
check it anyway as well as checking out all the other aspects of the 
installation. If you can, replace the feeder. You may be surprised at 
what you find.

73,

Alan. G4GNX

Hi Jim,

For high power Balun Applications, most critical parameter is Ferrite
core loss which causes core heating. Core loss, parallel resistance
(Rp), can be computed from complex permeability data from Fair-Rite.

https://www.kn5l.net/Balun-CM/Balun31-43/
Models FT240 10T with 31 and 43 materials. G.Zo is selected to indicate
maximum possible core dissipation watts. Maximum core dissipation
accrues when ground to antenna external conductor electrical length =
1/2 wavelength multiples. 1/2 wavelength multiples reflects ground
impedance to the Balun.

As shown, at 1.8MHz, maximum core dissipation for 1kW key down could be
4W for 31 material and 3.6W for #43 material. Probably not enough
difference to worry about.

The two CMRR traces, red and yellow, are below about -20dB. Difference
in choking ability is insignificant in this range.

The model includes a parallel capacitor for self resonance. Though is
not critical, as reactance does not result in heating. Core loss, Rp,
causes core heat rise.

All in all, not much difference between 43 and 31 for these two Baluns.

Hi John,

While I respect your engineering chops, you clearly don't understand how 
ferrite common mode chokes work. They DEPEND on the loss component 
coupled from the ferrite core, which has a broad peak around resonance 
of the winding. Fair-Rite's #31 material is MnZn, which exhibits two 
resonances. One is formed by the inductance of the winding and the 
capacitance between turns; the second is a dimensional resonance that 
results from standing waves within the core. #43 material is NiZn; these 
materials do NOT exhibit dimensional resonance, because loss is low at 
the frequencies where it would occur.

At HF, the two resonances in multi-turn chokes on #31 cores combine to 
provide a much broader resonance, comparable to what happened in 
stagger-tuned IFs. This has two implications. First, the broader 
resonance allows the choke to cover more bands.

Second, and more important, ferrite cores have wide manufacturing 
tolerances that cause the resonances to shift in frequency. The broader 
impedance curve formed by chokes on #31 material allows a designer to 
specify chokes that will work within a specified frequency range with 
that tolerance variation; it is NOT possible with the much narrower 
impedance curve of chokes wound on #43 or #52 material.

My "choke cookbook" is the result of first characterizing nearly 200 #31 
cores of a given size, selecting cores at the tolerance limits for each 
size, winding and measuring more than a thousand chokes on these 
"limits" cores. The cookbook is based on chokes working with all of 
those "limits" cores.

After seeing recommendations from a ham in the UK for #52 material, I 
bought 40 of these cores over a period of about four weeks, splitting 
the order between four franchised vendors (that is, ten from each 
vendor). I characterized those cores, selected cores at limits, and 
wound chokes using that ham's recommendations. I could not reproduce his 
results -- the tolerance variation moved their resonance away from their 
intended operating range.

I learned about dimensional resonance from a classic engineering book on 
ferrite applications by E. C. Snelling that a colleague found for me in 
the engineering library of the U of Chicago, where he was on faculty. 
Snelling's work is considered "the bible" by engineers working in mfg 
and application of ferrites. It's reference 7 in the AES paper, and is 
also referenced in the tutorial.

These concepts are discussed in detail in an AES paper from 2005 and in 
a tutorial I wrote for hams in 2007, the latter updated several times 
over the years.

Jim,

I only use my Bose QC-35 when:

1. on the cell phone.
2. mowing the yard/tuning my motorcycle
3. whenever using the K3 & K3s. 

The noise cancelling works perfectly with 
the blower from the Alpha 77SX right next 
to me, I only hear what is coming in from 
the radio. Why your QC-35 does not noise 
cancel when attached via cord is not 
normal, mine is a Godsend.

I also use a QC-35. When plugged in with a cord, the power must be on for
the noise cancelling to work. That also turns on the DSP which greatly
improves audio quality.

As far as I can tell, no. I operate with headphones, and never hear the tones.

Hi Jim,

The SimSmith model includes Fair-Rite complex permeability files, which
is the basis of the Ferrite model.

Hi Richard,

All K4 models utilize the same front-end circuitry (preamps, filters, etc.), so all will have virtually identical sensitivity for a given gain setting. These in turn will be similar to the K3/K3S.

Wayne,
Thank you.
  My main issue here is weak signals.    There are no
ham stations near me to cause interference.

A good antenna is what I ought to have but that is not happening.

Remember the noise/gain equation and how what determines sensitivity is
ultimately a systems noise figure.  ... when used with a transverter or an
EME preamp the  noise figure of the system will essentially be set by the
noise figure of the first stage.  Subsequent stages have much less effect
on the noise figure, as the noise contribution is divided by the gain of
the preceding stage.

Boy it fits the person asking the question.
There are reams of files and court filings against Hir-onono for harassment
when she ran or owned a company out here many moons back,? she a dike
as all the complaints were women.?? Of course everything was hidden and
charges dropped a she was the Dems toy and upcoming politician.
Probably knew Obozo well when he was here with the commie party.
I think if you looked in her purse you would find her commie card.

She is just the mouth of the party,? they know shes to dumb for anything
else,? and just feed her the papers and what to say on demand.

While it may not be a ?perfect? material, it was what I had on hand, and I measured over 800 ohms choking impedance on the band of interest. 

It?s definitely doing something useful.

I have your cookbook, and will use it for future projects.

I was not seeing any SWR shifts on this antenna. A check with an ohmmeter shows no shorts.

This antenna is currently on the ground due to other work on the tower. I?m considering replacing the antenna entirely. It?s been up over 10 years, and the traps could use re-work.

Using a Rig Expert analyser, no fault or bad SWR was indicated and I (wrongly) guessed that the 400W Guanella balun was breaking down at power over 100W. In the meantime I ordered a new 1KW balun made for that antenna, but before it arrived, during a QSO there was a catastrophic "occurrence" with all kinds of warnings and the SWR was off the scale.

I cut out a section either side and the remaining two pieces showed 'open' as they should. On visual inspection I find that the braid of the co-ax has migrated through the center insulation and is touching the inner conductor, indicating that a fair amount of heat has been generated. The area in question was right where the common mode ferrites had been fitted, although there were no tell-tale marks on the ferrites or the outer casing of the co-ax. It's fairly obvious that a high voltage node has caused an internal flashover which in turn has changed the characteristic which has resulted in a high current node which has generated the heat.

I just bought a pair yesterday at a closeout price of $170 from my local Costco.  They have been discontinued.  Costco online is now out of stock, but some stores still have them.  Amazon has them for $199 now.

My favorite headphones up to now has been Sennheiser HD 280 PRO but these sound great and eliminate the noise from my KPA1500 with the fan on #2 and a nearby water heater fan.  No comparison with my old QC2 headphones.

I also use a QC-35. When plugged in with a cord, the power must be on for the noise cancelling to work. That also turns on the DSP which greatly improves audio quality.

Jim,

I only use my Bose QC-35 when:

1. on the cell phone.
2. mowing the yard/tuning my motorcycle
3. whenever using the K3 & K3s. 

The noise cancelling works perfectly with the blower from the Alpha 77SX right next to me, I only hear what is coming in from the radio. Why your
QC-35 does not noise cancel when attached via cord is not normal, mine is a Godsend.

73,

Do the QC-35 rest on your ear or are they over the ear?

I presume that you disconnected the feeder from the balun when you did 
the DC Ohms test? If not, there is something wrong because you should 
see almost a dead (DC) short through the primary of the balun.

I must admit I put off replacing my antenna until I was forced to. Might 
be the way to go. :-)

Alan. G4GNX

They are over ear, which helps make the noise cancelling extremely effective, and also the headset is not tiring for long periods of use in contests, for instance. The prime day price of $199 on amazon is an excellent buy in my opinion.

Do the QC-35 rest on your ear or are they over the ear?

Over the ear - very comfortable.

Top rated (87) by Consumer Reports - tied with the new model.

I would be curious to know if the K4 has been tested on Amtor or Pactor.
The early firmware in the K3 was modified to work with these quick
turnaround modes.

How about latency for CW either wired or wireless?

How do you deal with battery life in contesting?

Stay safe!

Wireless introduces latency, wired does not. Definitely use wired for CW.

ED / W2RF

I use a bluetooth set from Avantree and there is no latency that I can
detect.  I operate CW almost exclusively, using a key paddle and copying in
my head.  I don't know how they would work with keyboard and speeds above
25 WPM

The rechargeable battery with noise cancelling on and Bluetooth off is rated at 40 hours.  It uses the same USB charging plug as my Logitech keyboard, so I have a charging cable on my desk.

I connect to my K3S with the cable, which is inadequate.  It's 4' long, lightweight, and flimsy.  The jack on the headphones is a sub-mini, 2.5mm, and the other end is a mini-phone plug, 2.5mm.  Amazon has several replacement cables that are heavier and designed for these headphones.

73,  Jim N7US

How about latency for CW either wired or wireless?

After reading a positive review and to reduces wires at my operating position, I connected a bluetooth transmitter to my K3/0 and tried a bluetooth headset.   The latency was so bad that I just could not send cw using my paddles.  I attached a wire to the headphones and the problem went away.

Sorry, but I need to correct a typo.  The cable included with the headphones is 2.5mm at the headphones and 3.5mm at the other (radio) end, so an adaptor is required, though not provided.

There are newer headsets claiming 40ms latency, but the host must support
the LL format. My estimate for the QC-35 which uses the ATX format is in the
range of 150-250ms. This may not be a problem at slower CW speeds for some
folks, but I couldn't tolerate it.

Here's an example of where the word "balun" blows up our thinking about 
problem solving. The "balun" you're describing is a transformer, 
sometimes called a voltage balun. Other things commonly called a "balun" 
are a common mode choke, which should look like an open circuit at both 
DC and RF.

The word "balun" should be eliminated from our use. I know of at least 
ten very different things that are called a "balun."

Jim. I agree about the MISS-use of the word balun. As the word is 
actually supposed to represent a balanced to unbalanced TRANSFORMER, I 
have used it in its correct sense.

If I had meant common mode choke, I would have said so.

If the OP is not using a balun in the true sense of the word, then he 
should say so.

Sorry, but I can't be held responsible for others' misuse of the terms.

I don't see why the word "balun" should be eliminated. That's like 
saying the word "resistor" should be eliminated because I actually mean 
to describe a capacitor, but can't be bothered to learn the correct 
terminology. :-)

AA4LR is using #43 ferrite beads on RG-313 coax. I am not sure what  
RG-313 is however there should be no ohm meter short unless he is  
using a hairpin match.  Perhaps there is a flaky connection somewhere  
in his system.  I had a lot of RF feedback problems with my K3S when  
using a corroded station in the Caribbean but no current warnings.

Analog radios have almost no latency, but it's almost impossible to find a
pure analog radio anymore. Most conventional radios switch over to DSP in
the IF stage, which introduces anywhere from a few ms of latency up. For
example, the TS-890s hybrid has about 25ms receive latency. Then when you go
to full SDR you probably get a somewhat bigger number, anywhere from 40 up.
But the real source of latency in current systems is Bluetooth, which can
run in the range of 200ms. New Bluetooth protocols aim to bring that down to
a reasonable 40ms, but they aren't widely available yet.

So for now, use wired headphones.

ED / W2RF

It?s a current (choke) 1:1 balun. Ferrite beads over coax. There are no turns, there is no primary.

Not wishing to pick a fight, but he said that he is using a balun rated 
at 1KW.

What you describe is a common mode choke and as I'm sure you know, that 
is not a transformer which is what I described.

I can see Jim's frustration. Folks really need to get to grips and 
properly understand the terms they are using, otherwise we get into 
meaningless arguments and false advice.

While I realize that precision in statements is important ? this is cutting a mighty fine point.  OF COURSE it?s the digital processing that causes the delays.  It?s perfectly reasonable to assume in this group that we know what we mean when we say that a ?wireless? headset introduces delay, and we?re not talking about interplanetary communications.  Context matters, and the context of this conversation is Bluetooth headsets ...

Isn?t the name apt, though?

A feedpoint choke like this does manage the interface from the unbalanced coax to the balanced antenna by inhibiting the flow of common-mode currents. Hence, Bal-Un.

Agree that the term is insufficiently descriptive.

?Balun? is also misleading because ?balanced? transmission line is a misleading idea. Whether the transmission line is coax or two-wire, it can carry both differential mode and common mode currents.

I prefer the words ?choke? and ?transformer?.

I?ve had other problems with this antenna when the 17m traps broke down about three years ago. 

Looking back at my station notes, I?m wrong. It wasn?t RG-313, it was RG-303. Sorry for the error. This is a small diameter (0.170?) coax with a solid teflon dielectric.

In this case, it wasn?t RG-213, but RG-303. The author regrets the error.

Sorry to pick you up on this Bill, but you've been rather misleading on 
your description. A current choke (common mode choke) is not even 1:1 as 
in a transformer, there is no ratio, primary to secondary. You rightly 
say that you're using a CHOKE which is NOT a balun "balanced to 
unbalanced transformer".

In the light of that, I apologise. My information regarding a balun is 
useless to you. Sorry to have wasted your time.

BTW I also don't understand where the 1KW rating came from.

73,

Alan. G4GNX

Analog radio microphones have been used in broadcasting and live sound

have been used to provide in-ear cue and monitoring for "talent." 
Neither could work in live sound applications if there was latency.

My impression of the Bobcat fire here in Los Angeles, which got to within 2 miles from me and is still burning 38 days later, is similar to Bob's: fire agencies simply let it burn for days without any urgency whatsoever, letting it advance into backyards in the northernmost reaches of Arcadia and Monrovia before kicking into firefighting high gear at the last possible second. In strangely similar fashion, the news media never really reported with any energy on the Bobcat fire. I still can't understand the almost total ignoring of this fire for so long.

I think the context of the conversation was Bluetooth wireless headsets (I
referred to them as "wireless"), which of course are digital. At any rate
that's what I was referring to. Sorry for any confusion.

DIGITAL introduces latency, NOT radio. ANALOG radio over short distances
does NOT add latency. In systems like Bluetooth, it is the A/D and D/A

I know I was asked by FEMA to head west to help as a COM-T. Unfortunately I am now disabled from a very rare infection that resulted in severe cardiac and pulmonary issues or I would have gone. 

There are firefighters fron here in NJ and nearby states that have gone out and some are there now. Resources from around the country have gone to assist.

Hopefully the fall will bring much needed rain to the west coast. In NJ we are about 7 inches behind on annual rainfall but just had a drencher the last couple of days with more coming Friday.

My thoughts and prayers go out to those affected by the wildfires and hurricanes.

2020 has been a CRAZY year!

I have been following this thread with interest. I am considering the Bose QC-35 headphones. I wanted a boom mic to go with, but I have not found one with decent reviews. Has anyone experience with one that works w the QC-35 II? I guess that by plugging into the headphone the boom mic disconnects the internal mic. It looks like that mic then plugs into my rig using a TRRS, and feeds mic and speakers. Is this the way it works? That would make the plug into the ear cup a speaker feed? I could see almost any good mic working, even if what I needed to do is run 2 cords: one for the mic and one for the audio. That would let them work for CW. And otherwise, there should not be a problem?

The simplest answer is when an area has numerous fires consuming homes, acres and a few lives in excess of the ?norm?; there will never be enough resources available in a timely manner. 

Every fire, regardless of which agency is responsible (Fed, state, local) is noted and prioritized And addressed, leaving some reserves for the more mundane events (90% medical aid, wrecks etc) and a smaller amount to apply as it hits the fan; including help from other states and countries (while protecting everyone from COVID as best as possible).  Herculean effort is a gross understatement this year. 

CA has exceeded the 4 million acre threshold (30+ dead); a record that no one wants... with another month (or more) of fire season to go (in the north, the south never closes).

Prayers for all the impacted; the level of destruction is beyond traumatic.

Hi Rich,

I wanted a similar result, that is noise canceling headphones combined with
a headset mic. After many trials, I came to the following solution:

	Bose QC35 headphones on wired connection
	Shure MX153B/O-TQG headset

They both are corded. The Shure fits over the ear and under the QC35 so that
it is barely noticeable.

I highly recommend this solution as providing both excellent noise
cancellation and superb audio quality.

Thanks, Ed,
It is helpful to have a recommendation with time under its belt. I browsed for this device. It seems to be terminated in  TQG / TA4F connector... I suppose that there is an adapter for this. Do you then have a way to mute the Bose mic? I don't mind wires. I am not happy with BT connectivity in general.

Would love to send some of our rain your way. Already 87.5? at my house near Atlanta this year. We?ve been close to 80? a couple of times before. Expecting to bust 90? easily.

Martin, very glad I found your post! Just did the conversion on my HS-5?s, to
take advantage of my K3?sub rcvr, but I was following the Hints & Kinks
article from QST (Jan, 05).  He never mentioned the extremely fine speaker
connecting wire, and I ended up de-soldering the white side, and breaking
the red side - drove me nuts for about two hours!  All continuity checked
out, with absolutely no sound from the headphones.

A search turned up your post, and the note about the ?very, very thin?
leads, and another check confirmed I had done exactly what you had warned
against.  I resoldered both sides, and I now have my favorite ?phones back,
in stereo!  Truly thankful to you.

Tony W3FLH

I think you have a skewed view of the situation, probably understandably 
so given your own vulnerability to that fire.? I can find tons of media 
information specifically on the Bobcat Fire with almost daily datelines 
when I do a Google search, and I know from personal experience with 
wildfires here in southern Arizona that agencies have to prioritize 
literally on an hour by hour basis how and where they deploy scarce 
resources.? Slurry bombers are about the only effective countermeasures 
in rough terrain (and even then only partially), since sending fire 
crews into those areas is pure and simple murder.

Here where I live (dry grass, dry trees, hilly terrain) the aircraft 
(slurry bombers, helicopter water drops) try to slow the fires while the 
fire crews mostly just dig in their heels and try to save the homes ... 
and there isn't much point in them doing so until the homes are actually 
threatened.? The fire that whipped through this area in 2011 burned 
EVERYTHING within about 50 feet of my home, but the fire crews wouldn't 
back off and they saved the house.? If you can find the Google Earth 
satellite pictures from July 2011 you can see what I mean (my .kml info 
is available from QRZ.com page) ... everything is black except for a 
cone where my house is at the pointed end of the cone.

With 4 million acres on fire in California within a short period of time 
I think it's unrealistic of you to think that there will ever be enough 
resources in reserve to cover everything in a situation like that ... at 
least not when you would like.

Years of mismanagement contribute to the fires. Forest Service and states
have not culled dead trees, allow logging, and not done controlled burns to
reduce the fuel. Building homes in canyons with Santa Ana winds also does
not help. Until there is a serious change in how forests are managed, this
will be a normal occurrence

The Creek Fire was burning through forests that were 80-90% bark beetle kill
in mountain wilderness. It is simply not possible to ?thin? that. From 2014 to 2018,
the number of dead trees in California increased from 11 million to 147 million.

Anyone who thinks there is a simple solution needs to think some more.

If you want to help, I already know of five Scout camps with major damage,
one in our council, near Big Basin. They will all need donations to rebuild.

Agreed.  I "fired up" my KX2 for a couple of 40M CW QSOs tonight.  Does  
that count? :-)

Hi,

actually I expected a little discussion on a qualified professional level in
this mailing list. Otherwise I would not ask here. But the topic does not
seem to invite to it.

Rich,

I use this https://www.amazon.com/gp/product/B000Z0EP3I/  which converts the mic to XLR and also boosts RFI resistance. For some this might be getting pricey for a headset and it's also possible that other solutions are now available (I got mine in Feb). But to me it offered the combination I wanted. The QC series Bose (any of them: 15, 25, 35) noise cancelling makes even extended operation such a pleasure, and with the Shure I can easily add a great mic.

With the QC-35 I don't think the internal mic is passed in the cord. At any rate I have not had a problem with it. The 15 and 25 do include it, but if there is a problem it could be easily corrected with an adapter. I have a 25 on one rig and did not need one.

TKS,

Thanks, Ed,
It is helpful to have a recommendation with time under its belt. I browsed for this device. It seems to be terminated in  TQG / TA4F connector... I suppose that there is an adapter for this. Do you then have a way to mute the Bose mic? I don't mind wires. I am not happy with BT connectivity in general.

Amen to Walter's response.  Sure, there are plenty of examples of things not
being done quite right, but the real truth is that things are so far out of
control it's almost amazing that anything got saved in the fires!  Our
resources are being overwhelmed!!!

 

Until we get our heads screwed on right, and face up to the fact that global
warming is real, this kind of thing is going to continue.  It's already too
late to make things get much better very quickly.  The desert "burned up"
this summer from a record number of excessive heat days (over 100 F.),
California, and Oregon, and Washington burned up literally, and our southern
regions are getting slammed by historic numbers of hurricanes.  This is not
just happening by "accident".  It is self induced!  We are destroying the
planet slowly but surely.

 

If you really want to better understand what is happening, and why, I
recommend you view David Attenborough's latest documentary "A Life On Our
Planet", which is currently available on Netflix.  It's a superb explanation
of how we got where we are, why we are seeing all these fires and floods,
and what we have to do SOON!  Ignore it if you will, but that doesn't solve
a thing!  Making empty excuses doesn't help either.

The Creek Fire was burning through forests that were 80-90% bark beetle kill

in mountain wilderness. It is simply not possible to ?thin? that. From 2014
to 2018,

the number of dead trees in California increased from 11 million to 147
million.

 

Anyone who thinks there is a simple solution needs to think some more.

 

If you want to help, I already know of five Scout camps with major damage,

one in our council, near Big Basin. They will all need donations to rebuild.

Bose makes a QC35 II gamer headset. It comes with a boom mic which plugs in
in place of the cord. Bose usually sells these accessories separately.

Not a professional here but I think it's a very interesting topic and 
wonder if it applies to manual keys as well. A typical solution for 
semi-automatic "bugs" (probably mis-adjusted) is to place a capacitor 
across the terminals to alleviate "scratchiness".

I have an old Bunnell Double Speed  "cootie" key that, if the contact 
spacing is adjusted too wide, will produce erratic contact bounce keying 
on the K3. I've never thought what effect a resistor across the 
terminals might have.

FWIW, regarding wetting current-- we used to have DSL internet over 
telephone lines at my house, which the provider was not interested in 
maintaining, trying to push subscribers to fiber. The lines were allowed 
to deteriorate badly for a couple of years before copper was finally 
retired. During this time I solved the noise and low DSL speeds very 
successfully by placing a suitable size resistor across the line-- the 
constant current through oxidized connections & corroded terminals kept 
the noise at bay. As I recall, a 15ma "sealing" current was enough to 
keep it noise free but not enough to off-hook the line.

The Bose QC-35 gaming headset seems to be set for release on Oct 20.

 

This is also an option (for only $27):

https://www.amazon.com/Cable-Boom-Microphone-Playstation-QuietComfort/dp/B07W3W9LHV

I?m ordering one to test.

Thanks, Ed,
It is helpful to have a recommendation with time under its belt. I browsed for this device. It seems to be terminated in  TQG / TA4F connector... I suppose that there is an adapter for this. Do you then have a way to mute the Bose mic? I don't mind wires. I am not happy with BT connectivity in general.

I have one of these aftermarket boom mics for my QC25. It works fine. Just
be careful of the wiring of the L and R channels because the adapter
splitters sometimes switch them.

Hi Wolfgang,

A DC wetting current has been common in relay circuits that would 
otherwise just be switching low level alternating current signals. I 
recall seeing it applied to RX front end filter switching relays.

Mike VP8NO (G3VUI)

In radio & TV broadcasting we used "Dry" contacts for microphone switching.
Both relays and switches.
The contacts actually wiped a tiny amount as they made or broke.
Usually the contacts were actually gold plated stiff wires that were
mounted at a right angle.

My heart goes out to Alan and Bob for their losses.  Thankfully, they got out
OK.

Walter points to a scientific fact (so many dead trees) that explains the
huge fuel source available to burn.  That is not a "normal" situation.  We
face similar challenges in NM where we have experienced drought and bark
beetle infestation for many years.  We're hoping to avoid "the big one" that
starts in the mountains east of Albuquerque and takes out all the TV/FM/LMR
stations along with ham repeaters on Sandia Crest.

I helped clear brush and small trees from another ham's property when a fire
(human-caused like most) was approaching his property several years ago.  We
moved all valuables from his home to his metal "barn" in case the fire got
to that point.  Fortunately, it stopped within a mile.  Two other hams in
those mountains were not as fortunate.

We have sent NM fire crews to CA again this year.  Like COVID-19, this
subject is now too often linked to politics instead of science.  As members
of a science-based avocation, let's keep the discussion (probably too long
already) based on science.

73, Bill, K8TE

Hi,

i posted the article here for discussion, because I can't judge it myself. 

I think that Elecraft had a little idea to design the keyer electronics of
the K3 as it is.

Interesting is the difference to the K2, where the resistors R1 and R2 were
changed in revision "B". Again I can't judge if this had anything to do with
this topic.

OK, I'll just leave it like this. Maybe somebody will have some experience
with it after all.

Thanks a lot
Wolfgang, DL2KI

Sliding off topic a little: in designing some outdoor industrial control equipment I was required to use some chunky, robust push buttons that were good for high voltage, high current but no good at 12V. Getting to logic level I had to build in a lot of extra current from 12V to ensure a good switch over, I think some 30mA or so.

Using a favourite pre-war Morse key on vintage valve gear, it worked perfectly, but on modern solid state equipment it was very intermittent and I didn't want to make an interface. Solution, clean the contacts. Conclusion: modern gear needs better contacts than the old stuff.

I think there could be more than just clean contacts involved. As I 
mentioned, on my old cootie style key, whose contacts have a mirror 
finish, when the contact gap is set too wide the keying will be erratic 
on the K3; no doubt due to my particular sending style combined with the 
relatively "hard" action of the key. When a smaller contact gap is used 
the keying is fine.

I have no idea how key contact de-bouncing is accomplished in modern 
rigs. I assume there is some coding in the software in addition to 
whatever electronic components are used. I am wondering if it would be 
worthwhile for a modern rig (K4?) to make the parameters in the debounce 
routine available as a user option in the software so it could be 
tailored to individual keys...

73,
Drew

Hi all

I?ve signed up to the Elecraft ?wish list? of K3 accessories but its unclear if or when Elecraft will resume availability of K3/K3s accessories.

In the interim, I?m interested in purchasing a KDVR3 if anyone has one spare.

I suspect from my own undocumented tinkering that contact geometry is also involved. Back in the day when currents were higher, we'd burnish contacts to flat, parallel surfaces. The instruments and controls that I have in mind were routinely serviced. They were routinely serviced because contact were observed in DC control systems transferring metal from one contact to the other, resulting in a pit on one side and a peak on the other.

Perhaps modern key contacts can benefit from at least one of the contacts coming more to a point. This would increase contact pressure due to the reduced contact area, and would result in higher charge density near the tip, and therefore higher potentials as the contacts closed. Two factors: tip radius (smaller is better) and tip contact area (more is better).

I have found for some keys with metals that corroded more quickly that periodic light cleaning is all that is required, but for those keys with less active metals, reshaping worked well to reduce false contact closures. I still stutter on some occasions on all my keys.

Looking at the current manual (Rev C5), the error is referenced on page 47.  Looks like the radio is not seeing the 2 Meter module.  Troubleshooting is to make sure it is correctly installed, and to refer to the 2M/4M installation manual about how to do that.

Despite what hat website says, there are no kits available.  Tom Hammond 
was SK several years ago, but his local radio club has preserved the

All the instructions are there, and I believe Tom used FAR Circuits for 
his boards.  An email to FAR Circuits may turn up a board for you.

When I built a single level paddle, I decided to use silver for 
the contacts after hearing that all the corrosion products of 
silver were conductive. I soldered two short pieces of silver 
wire, contributed by a jewelry maker in the family, at right 
angles to each other on the contact bases.

In spite of mostly sitting on the shelf for five or so years, 
presumably corroding, this system still works quite reliably. I 
have recently been using it with a Rockmite, and it shows no 
signs of intermittency.

Another solution is to use hermetically-sealed contacts.? I built a 
light-weight, single-lever key paddle using microswitches for the 
contacts.? It worked very well and never had problems with scratchy 
contacts.

I have two antennas for 40M, a Carolina Windom and a full-wave parasitic 
sloper, the latter fed through a 4:1 balun.? The 1500's tuner handles 
both antennas nicely, and I have trained it on both of them, but when I 
switch from the Windom to the sloper (on an external antenna switch), 
the output power changes from ~1400 watts to nearly 1700, often 
triggering a high current fault.? Any way around that?

Pete,

I would say re-tune after switching with the external antenna switch.
If you have tuned to one antenna (on a single port), and then change the 
load slightly (by switching to the other antenna), a re-tune is necessary.

Thanks Kent,

I already have that in my bookmarks and refer to it often.
Thanks to you and your club (especially Jim Biggerstaff) for maintaining

There is a lot of value there, especially for K1 and K2 owners.
I also have much of the information here on my networked hard drive.

I guess I wasn't clear - when I see this overpower/fault combination, 
the sloper is matched around 1.2:1, it's just that output power and 
current draw jump up to fault levels, so a retune wouldn't help

I don't think so. After I've switched to the sloper, the ATU switches 
properly to the parameters for it.? The only thing that is unexpected is 
that the correct level of driving power for one antenna pushes the amp 
to 1700 watts on the other.? If the ATU also remembered the driving 
power level for each set of parameters, that would solve the problem, I 
think, but that may not be practical.

I suspect an effective solution would require the KPA1500, or a smart external controller, to have an interface with the external antenna switch. On sensing a switch change the key line should be inhibited and not re-enabled until the appropriate tuning solution has been selected and verified and the drive power has also been set and verified.

I face a similar problem with my KAT500/KPA500 combo as I have a manual antenna select switch in the back yard. My smart controller doesn't help because it doesn't know the switch selection (yet).

A solution that requires the bin stack to remember power for each solution is probably doomed to failure until it's possible to "reserve" tuning solutions to stop them being pushed off the stack.

Last year, I found a kit offered by WB3AAL and I ordered. Unfortunately, 
I learned later that Ronald became SK in 2018, but the order page was 
still up at the time I ordered and I didn't find his passing on the 
reflector either.

I think many people enjoy the kits Ronald made and I am very sorry to 
have learned that I was too late. At least, if you "find" the kit 
offering, you know not to try this.

Message-ID: <0eb301d6a343$588536f0$098fa4d0$@frawg.org>

All,

 

My KPA500 amp, (#2208 kit built), was acquired used but well cared for. It
has operated perfectly for several years until today. I was in QSO on 40M
when the amp threw a fault and the signal strength of received signals
dropped markedly. When I put the amp in standby, the signal strength of the
received signals returned to expected levels. I do get a TX power indication
appropriate to the drive level on keying up. This issue does not clear when
the power is cycled.

 

I have done a cursory RTFM and find there is not a circuit diagram in the
manual nor a description of how to interpret the fault (beyond the plain
text listings). I have not yet had the time to dig into the archives at
Elecraft or look through the files on the website.

 

If this "symptom set" sounds  familiar and/or you can point me to where and
how I could troubleshoot, I will be quite thankful.

 

Best regards,

Geert,

The kits that Ron WB3AAL (SK) offered were exactly the same kit as Tom 
Hammond N0SS (SK) offered.  Tom passed the baton to Ron for the kits 
some long time ago (2015 or 2016).  Ron added nothing, and in fact 
offered Tom's documentation for the instructions.  One thing that Ron 
did add was the option for an LED in a keycap - the origin of that idea 
was mine, but I never documented it.  LA3ZA did document my work (plus a 
bit more), see 
https://la3za.blogspot.com/2011/05/five-k2-leds-in-buttons.html for 
details.

Unfortunately, stuff stays on the internet for a long time, even when 
the originators have sadly gone SK and their kits are no longer available.

I had frequent email interactions with Ron while he was selling the kits 
- none bad, but always informative.  I built and installed many of those 
kits for my customers.

If anyone would like to "pick up the pieces" and begin supplying these 
kits, I am certain there would be many 'takers'.  I believe FAR Circuits 
can supply the boards, and if that is not possible, Tom's documentation 
has full size board layouts for anyone wanting to make their own boards.

Jack,

This fault has been reported several times and usually turns out to be a 
problem in the KPA500 T/R switch area.
I suggest you consult with support at elecraft.com for guidance on how to 
proceed (fix it yourself or send it in for repair).

Do you use both antennas on the same frequency?  I do not have a KPA1500 but
I am curious how the tuner can remember the two different settings and know
which trained setting to use when you switch antennas. (assuming that you're
not also changing frequency).

Back in the 1960's-1970's I spent many hours cleaning contacts when I 
worked at the local telephone company. Relays that had little or no 
current flowing through the contacts usually would only have to be 
cleaned with paper, known as Bell Seal Bond Paper 20. If this did not 
work, we used a contact burnisher tool.? These low or no current flow 
contacts would usually only have dirt buildup and did not need any sort 
of filing to clean them up. Filing contacts usually just damages the 
contact surface. The scratcher from a pack of matches can also be too 
abrasive. Plain white paper would be a good choice.

Contacts need tension, and in some cases "follow". Follow is where the 2 
contacts come together, then continue to move or follow each other 
together, for a distance. This helps to clean the contacts and keep them 
clean. If they just touch, there is a possibility of contact bounce.

Fred?KF9GX at FAR Circuits does have them, they're four bucks each plus 3.50 for shipping up to ten. (Possibly more outside the US.) Thanks Don for pointing this out!



I believe it's the SMD version which is fun to assemble if you're a masochist! If someone gets around to ordering the parts to go along with the board, it would be great if they could post the list here. I believe the chip is obsolete but still available.

Despite what hat website says, there are no kits available. Tom Hammond
was SK several years ago, but his local radio club has preserved the
content on his website.
All the instructions are there, and I believe Tom used FAR Circuits for
his boards. An email to FAR Circuits may turn up a board for you.

Thanks, Dick.? That video squares with what I've been doing, but it 
doesn't address my original question, which is:

When I have set the drive to give me ~1450 watts on the Carolina Windom, 
and I need to switch to the sloper on the same frequency, I find that 
the drive level that produced this output on is too high, resulting in 
excessive output power - well over the legal limit.? To get legal again, 
I have to manually turn down the output power on my K3.? If I then 
switch back to the Windom, I'm suddenly only running ~1000 watts out.? 
Is there any way to have the drive level not only set band by band, but 
antenna by antenna?? K6XX's video seems to demonstrate 6 widely 
different antennas with very different matching solutions required, all 
producing the same power output for the same drive (unless, of course, 
the K4 is better in this respect).

 When Ron's CW Indicator kit became unavailable, I drew up a board in KiCad and had OshPark make some up.??The masking makes part placement a bit more critical than the original board.? But it does work fine.
NJR has apparently stopped making the PLL decoder IC (NJM2211M)Both Mouser and Digikey are out of stockThey seem to be available elsewhere.? But who knows if they are real or knockoffs.
I have shared the board on OshPark.? Here is a link:

OK, I operate portable and often at night and lighting has to be managed to
reduce critters of the night dive bombing me when operating.

Wearing a head mounted light causes the critters to go into a frenzy so
does not help.

I often wonder what it would be like If the buttons and/or knobs could be
either back-lit or maybe they could be lighter in color to help nighttime
operation.

As it stands, the k3 is very hard to see if i need to use any front
controls.

Placing a light behind me has worked for me but at times the critters
wander away from the light and use me as a target for harassment.

Anyone found an alternative to what I have tried?

I have used jse-repair on ebay to make covers for the Kherd.  Some are
stock, some he will make custom.  I had him make custom covers for my
KPA1500 rf deck and PS.  He made a single custom cover for my K3/P3 (one
cover in the dark to bind them).  He will add back flaps, headphone/mic
slits, callsigns for an extra fee.  He makes covers for the KAT500/KPA500
combo stack, K1, K2, and all sorts of gear (even an LP100A). I don't think
he has a K4 cover yet,  but all you need is a measuring tape.

As usual, should you be caught or killed, Eric and Wayne will disavow any
knowledge of your actions-and I have no relationship with JSE-REPAIR, his
successors or assigns, and any similarity between people living, dead, or
undead, is purely coincidental.

I use 2 red LED lamps. One is a fairly bright flashlight that uses 4X AAA. The other is a small flat lamp with a pushbutton-slide switch. It hangs on a locking ring, like you'd put keys on. It is push to light, slide to stay on.

You can find them for sale for folks who star gaze. Been happy with them for years. When it is dark, even the little one seems pretty bright, and they don't seem to attract bugs. Double plus...I get to keep my night vision, and few bugs. I wish that the LED panels on the KX were dimmable in steps. It's way too bright. I looked into what it would take to mod the circuit, and it was not as simple as I'd like. Doable. Unfortunately, it seems, the original design didn't anticipate that folks would want to dim it.

The face, keys labels, and display are all clearly visible in red light. I have not see a headlamp with red LEDs, but I'll bet it exists. You'd want it to be fairly dim, in my experience. My little CR2032-powered keychain red lamp is plenty at night once I have my night vision. I carry the big boy JIC I need it. 
---
I just did a quick search for headlamps, and didn't see any that I'd jump for. I am seriously thinking of putting a small patch of velcro on the keychain red LED, and then I can mount it wherever. Right now I keep it hanging from a button hole so that it is always handy in the field. I'm thinking that sticking some velcro on a ball cap bill would work fine.

Other than a coax switch on the RF input, would there be an easy way to
select the enhanced control of the 1500 between a K3s & Flex 6400.

Both radios will be set up for enhanced control of the KPA. Can the
interface cables for both radios remain connected and you just reconfigure
the KPA menu for the different radio when selecting the RF drive from
either? Is there any shortcut?

I have 2 of them, but I think that they are too bright for close work. Great for getting to and fro. Great for macro work at a campsite. The ones I have are not dimmable. I also have some by Princeton (I think). The are very nice (white), but not dimmable.

I've had my light for ages, so decided to check out the Chandler site.
https://www.davidchandler.com/shop/night-reader-pro/?gclid=EAIaIQobChMIjPq2nZy57AIVhIjICh1GdQRXEAAYASACEgJIIPD_BwE

I like the battery life on my older Night Reader. I think that I will pick up one of these, too, because they are dimmable. I'd want it to come on dim each time, and these can. They also can come on bright immediately. Not head mounted, tho. Too bad they don't make the original Night Reader, because I use it all the time. It always comes on dim, so I don't have to hold the button to set the intensity. And I have used it regularly for years. No problems. I like my Petzl and Princeton lights, too. The convenience of head mounted.

The battery lasts so long on the NR that I don't mind leaving it on and letting it hang from my shirt.

If your looking at red lights and want to avoid the head lamp or other
such impediments to operating you should be able to incorporate the
Universal Power Red Led.


https://www.portableuniversalpower.com/product/nano-led-red/



I have one I bought in the USB accessory pack and quite pleased with

be able to power it a variety of ways and directions as needed.

Good question.
Long answer that I'll keep short.
In days of old, mariners wanted lights that they could see by, but that are not too visible otherwise.
Enter red lights. Humans eyes are not very responsive to red light. More to blue, and max for green.

But now imagine that you are on a ship, and you want to see stuff, but not be too visible to other ships (military use). So you use red light. It's not discernable as much as white, green, blue...from a distance.

So we continue to use red.

Night vision is pretty sensitive. You'd be surprised at how much you can see at extremely low levels of light. If color rendition is not an issue, then night vision, using the rods, rather than cones, is not a bad idea. But if color rendition is important (think nav charts [I sail and fly at night]), then very dim white light might be more useful. Downside is that the cones, which we use for color, are not nearly as sensitive as rods, which are for shades of grey. So there are trade offs.

I don't see why green or blue could not be used at very low levels. Your eyes are way more sensitive to green, so you could possibly get by with much dimmer green or blue light than red.

There is way more...but this is a good start, and I'll wrap by saying that any of the colored lights will have drawbacks. Depends on what you are looking at. For me, red is a good choice because I can see all my radio gear clearly using a red light, and because it is readily available in the low power that I want. Green and blue (and yellow, etc) are also available, but at higher power. I don't want to overwhelm my rods and then await recovery.

First, I?d like to wish Rose well in her well deserved retirement!

I do recommend JSE-Repair for covers.  I started with him on EBay, but now work direct. I am very impressed with his covers, and have them for a number of my vintage rigs.  I had a minor problem with one order since EBay did not send him the message I left for him.  He made it right, and I was very happy with the result.  The covers are of excellent quality.

Another way to roll your own is to simply use an inexpensive red LED, and an inline pot. Hadn't thought of that for ages, even since I got my other red lights.

On the subject of RED LED Headlamps, I have a Energizer - it has two red 
LED's + three white (variable brightness) that cam be selected.? I 
picked it up at Walmart a few years back.? It was in the $10 - $20 
range, I think it was $13..? (cost may be more now).? 3xAAA batteries. I 
don't find a model number.

I installed dimmable "old-fashioned style" lamps in my shack. I like the soft glow. They dim to a deep orange, but still enough light spectrum so that I don't have color recognition problems. I'd recommend anything in this vein...dimmable white light, or similar. I kinda went with orange because of the current ideas regarding using blue lights at night when trying to wind down. It gives a soft warm light so that when I reach out to caress the knobs of the TS-830...er, adjust the finals...

Gary, I have a small USB lamp that I plug into my laptop when operating at night when there is no other light.  This lamp has a switch for high or low light.  Low light is usually enough.  Doesn?t prevent bugs, but probably minimizes them.

Red is used because the rod cells, that are used for night vision, down 
to a point where they are almost quantum limited 
<https://www.cns.nyu.edu/csh/csh04/Articles/Rieke1998.pdf>, have a peak 
sensitivity for greenish blue, but are very insensitive to very deep 
reds, whilst they retain some sensitivity to the high frequency limit of 
the blue cone cells.  Night vision doesn't have the same spectral 
response as a monochrome camera.

Light of a colour to which they are sensitive bleaches the sensor 
pigment, reducing sensitivity.

Ideally, you don't want to use the brightest red LEDs, but rather those 
with the longest wavelength consistent with an adequate remaining cone 
cell sensitivity.

See <https://midimagic.sgc-hosting.com/huvision.htm> for typical colour 
sensitivity curves.

Subject: [Elecraft] Elecraft CW Tune led
Message-ID: <20201016172313389@smtp.email-protect.gosecure.net>

I have an idea which should work as an easy to build tune indicator.  I have used an LM567 tone decoder (8 pin DIP) which costs $2.22 from Mouser electronics.  The Mouser data sheet shows possible circuits.  I use it to drive my telegraph sounders from off the air CW signals.  I set mine up for about an 80 Hz BW and for 600 Hz signals.  The drive level is not too critical and it seems relatively immune to weak adjacent signals.  It will take a handful of parts, but should work just fine for your purpose.  You could even build two of them and have one peaked on say 580 Hz and one on say 620 Hz and both would flash if you tune to 600 Hz.  Even a 3 light display if you like lights a red one for just too low, a green one for right on freq. and a blue one for tuned just a bit to high.  I use a potentiometer to set the center frequency, although you could replace this with a fixed resistor when you get it right.  The LM586 can drive (or sink ?) up to 15 ma, so should be fine directly driving a 5 ma or less LED.  If questions you can reply off list to my ARRL or QRZ e mail.   I posted this since others may also have a use for these ideas.   Rick  KL7CW

The Petzl Tikka headlamp has a red LED mode. I like them because 
they seem to be reasonably reliable compared with the other 
small, inexpensive, headlamps I have used.

(One of the other headlamps I otherwise liked kept the battery 
compartment closed with a thin loop of plastic. After changing 
the batteries only a few times, the loop broke, the battery 
compartment wouldn't stay closed, and the contacts on the 
flopping lid no longer completed the circuit.)

I will add, the Tikka has 3 levels of white light and one of 
red. It also has a red blink mode, if you can think of a use for it.

If you are trying to avoid insect attacks, the best color is one 
they can's see. If I remember correctly, most insects see well 
in the blue and UV range.

I have a few very useful lamps and light-emitting objects. I wear a
RovyVon Aurora A7 keychain light on a bead chain around my neck 24/7. It
has a handful of light levels for the main LED at the front, from 3 lumens
to 650 lumens. (The older 550 lumen version had a smaller battery and a
dazzler strobe on the main LED that the updated 650 lumen version does not
have.) There is a lantern-mode white light on the side that has 3
functions: low, high, and a flasher mode. There's also a side-mounted UV
LED (purple, "black" light). The shell of the flashlight is
glow-in-the-dark blue, and is "charged up" by the UV light. When you turn
off the light the case glows bright enough to see what you're doing. I find
it works great for a night light that doesn't wreck my night vision, but if
critters are going to be attracted to it, that may not be ideal. NEBO makes
a little keychain light, the MYCRO. It has several brightness settings for
the main white LED, but also has a separate RGB diode that they have set to
give green or red. They're both very low light level, probably around 1
lumen, but it's enough to see by. Both are charged using microUSB and have
fairly short charge times. They're both seriously durable as well.

I also plan to experiment with electro-luminescent wire. I have a nice
length in white and one in red. The red is particularly nice, bright enough
to see and even read by. Stretch it out where you need light, turn on the
inverter on the battery box, and there you go, light. My only concern is
that inverter. I haven't checked to see where it's emitting the worst
noise, but I would expect it to give off some amount of RF noise somewhere,
so it might not be ideal for radio operating, depending on where on the
spectrum that noise falls. It might be low enough and on frequencies that
won't matter to Amateur use, but I can't say for sure as I haven't tested
to see where the birdies are chirping. The benefit is flexibility,
relatively good light output, and low cost. The potential issues are in the
necessity for a high-voltage inverter that could put some nasty hash
somewhere we don't want it to. It might be shieldable, I don't know. Anyone
test such stuff for noise output?

Message-ID: <57638c08-2fa2-1923-d539-d03fa68d7a8d@cox.net>

I followed N4ZR?s thread and did not see a solution.I have the same 
problem as Pete.I?ve got two antennas on 3 bands.I?ve put the tuner 
settings in all the bins on those bands for each each antenna.Neither 
antenna has SWR over 2.5:1.I can then step through the bins with RF on 
each of those bands with ONE antenna with no problem.However, the tuner 
settings were made with 40w.

If I am in a contest and decide to quickly change antennas to call 
someone, the tuner doesn?t recognize the antenna change until RF is 
applied.I apply the same drive power ~30w and before the tuner selects 
the new setting, it sees the mismatch and output jumps to over 1700w, 
high SWR is displayed, and a fault occurs.The only way I can avoid this 
is first go to STBY, apply RF and wait for the new tuner setting to be 
sensed and applied, then go back to OPER.? To go back to the original 
antenna I have to do that all over again. I don?t think this is how it?s 
supposed to be, but I think there must be no solution.How can we go from 
one antenna to another without this problem?73, Jim W6YA

If I am reading this thread correctly you have one coax from the KPA feeding a remote antenna switch.  If correct how do you expect the KPA to know you switched?

Petzl does make dimmable red ones.  However, being an old-timer, I usually
use an Orion flashlight that is very dimmable, and worn around my neck or
held between my teeth.  The Petzl ones I have have to be cycled between red
and white to get to red dim, an offensive move at a star party.  The best
one I have ever used was from Crazy Ed Optical, but I cannot find a
replacement bulb for it.

Dave, yes, one coax from the amp to a manual switch.? Your question is 
the same as mine.? Somehow the KPA1500 should know by sensing a rise in 
SWR and shutting down most of the drive power or output somehow so the 
tuner can go through its motions without excessive output or a fault.

Jim, If it is a manual switch then must be a short run from KPA to switch so why not connect to ANT1 ANT2 on KPA and switch with KPA.  KPA stores separate solutions for each ANT.

I'm doing the same thing you are, Jim -- a dozen or so antennas, often 2 
or 3 for the same band. I've been lazy about training the KPA1500, but 
it is smart enough to switch between saved tunings within a reasonable 
range.

I suspect that, to have the system automatically change power in the 
manner that Pete needs, Elecraft would need to write software to 
remember and change drive levels from the transceiver on command from 
the KPA1500.

My solution is an LP100A with sensors inline with the amp outputs from 
both stations in my SO2R setup, and I manually adjust drive levels as 
needed. The LO100A is positioned right in front of me, so I can't miss 
it, and I have it set for peak hold, which gives me a worst case number 
for power out. My K3s do a bit of power hunting when I adjust power, 
starting high on the first dits and dropping back to the intended 
setting, so I often need to do multiple tweaks of drive level to get up 
to legal limit.

73, Jim K9YC

Jim, Thanks for the info.? You understand the problem for sure.? Dick is 
being very helpful now, but I'm getting erratic data for him because 
switching between antennas sometimes only results in "NEED TUNE PWR" 
with OK result after a few seconds, and other times I get the fault due 
to initially high SWR and high power output.? I'll probably go with 
switching to STBY before applying RF to the new antenna.? That way the 
instant mismatch won't create a fault due to 1800w output!? BTW I hope 
your house was unaffected by the fire.? I feel badly for Bob.

Dave.... that ANT1 ANT2 arrangement will not work with my setup for 
other reasons.? Thanks anyhow for the suggestion.

Thanks for posting this.

https://www.blackdiamondequipment.com/en_US/spot-lite-200-headlamp-BD620662_cfg.html?dwvar_BD620662__cfg_color=Octane#details
3 yr guarantee
Low 6 lm Not sure if that apples to both white and red.

Petal (sic) had one that interested me, but for 60USD
https://www.petzl.com/US/en/Sport/SPECIALIZED-headlamps/TACTIKKA-PLUSRGB
5 yr guarantee
Low white 6 lm, RGB 2 lm

Both posted low light level specs where I'd want them, meaning that I prolly will replace my aging Princeton and Petzl headlamps in the near future. I have also some other BC lamps, but not headlamps, and I agree that these have done me well.

I won't give up my Chandler, and will likely update my keychain lamp for ~12USD.

BioLite has some great products overall, but I don't think their head lamps compare well
https://www.bioliteenergy.com/products/headlamp-330?variant=12623824289891#
1 year limited warranty
Won't go as low as I'd like for low. 100 lm. So they are just not what I'd want for a night groove with my radio.
But they are really well designed, and so are the other products.

Funny you should mention that. I have a friend in LA (the city, not the state ;-) who runs a theatre sound and light company. I was visiting one time, and went on location to "help" so that we'd have more time together.

That night during a performance, an elderly person fell in the theatre, and as I was nearby with a light in my pocket, I hustled over to help the staff who responded quickly, but without a light. Later, J asked if there were anything that I /didn't/ have in my pockets. Well, sure...it was suit and tie, after all ;-)

Y'just never know...

Jim,

I have been following the thread.  Same, same here.  K3 driving the KPA1500, using AN1 jack only to a 6 PAK that is controlled by a Bandmaster V connected to the K3 for band data.  I am going to try OPER / STBY trick when changing bands.

Subject: [Elecraft] K2 Problem
Message-ID: <76e111aa-bac4-94ef-5be6-7e0d92481095@comcast.net>

I've got a problem with my K2 and would like some advice. S/N is around 
1500, and I built it in mid 1999. No problems with it since.

The problem started with a complaint from a nearby (8 miles away) ham. 
He was seeing regularly spaced spurs across his passband when I 
transmitted FT8 (with a XV50 - 6 Meter transverter). I double checked 
his complaint with a friend who is around 35 miles away. He saw the same 
thing but the offending signal (of course) were much weaker.

I did a LOT of debugging of the system, assuming ground loop(s) were 
causing the problem. I actually found and fixed some problems with 
ground, but there are still spurs.

Recently I decided to stop focusing on ground and just simplify my 
setup, which is quite complex (2 IF rigs, 7 transverters and multiple 
power amps). Box by box, I disconnected things until I was left with 
just the K2, a straight key and a dummy load. The spurs are still there. 
Even the transverter is not connected. And to make sure that grounding 
is not an issue, I powered the K2 for awhile off a battery. Probably 
more interesting, the spurs are there even when the K2 is set for CW!

With the K2 set to CW and 28.100 MHz, the significant spurs are (with 
respect to the carrier):

+558Hz -39.2 dB

+296Hz -36.7 dB

+178Hz -25.6 dB

-178Hz -25.5 dB

-306Hz -39.0 dB

-558Hz -40.0 dB

I also ran the K2 set for SSB? with a 2-tone generator into the mic port 
and the IMD looks fine .. around -29.5 dB). But those same spurs are 
present on either side of both tones. (I? didn't take actual 
measurements but by eyeball it? looks like the same pattern as with CW). 
I have no doubt these levels are strong enough to cause mischief on FT8.

The measurements were done with an HP8566, in good working condition, 
and I trust it.

I can't imagine this is "normal" for the K2.

I left some phonemail at Elecraft asking for a callback a few days ago 
so I could discuss this, and I'm sure I'll hear back from them some time 
soon. (In this age of pandemics, I have no doubt they're overwhelmed).

But in the interim, is there anyone who's a real expert on the K2 who 
would know a) how abnormal is this? b) what might be the cause?? I don't 
think I'll? fixing? this myself unless some expert says something to the 
effect of "Oh yeah, I saw that a few times, its usually caused by X". 
Hopefully that's what will happen and I'll just fix "X".

Thanks in advance for any help.

73 & stay safe,

Watching this thread with some interest, as I use my K3 to drive
transverters when roving in VHF contests, and it's hard to see the front
panel controls at night. I tried making a light with a bit of aluminum
angle stock and a short strip of white LEDs (the kind that come on a long
roll), but even with a dimmer in line it was too bright.  Maybe if I tried
it with a short strip of red LEDs it would be better.

Kinda reminds me of the red lights we used in the darkroom when developing
film back in the day...

The lights in the C-130 on our nighttime airborne missions in SE Asia 
were deep red to preserve our night vision, the trip to the jump target 
was in the dark.? The effect of any light above the bottom end of the 
visual spectrum on night vision is dramatic.? I'm a monochromat, I don't 
really know what "red" looks like to everyone else, and my dim light 
vision was really good, but anything higher in the spectrum killed mine 
just like all my troopers.? The fact that I can adjust the LCD 
brightness on my K3 is really cool, I normally run LCD at 2 or 3.

The one problem I have is I can't see the numbers on the keypad keys in 
any light.? Fortunately, I know what the keypad looks like. [:=)

Precisely what I thought, Jim.? The KPA-1500 already adjusts the K3's 
output power when the amp switches to OPER, from 100 watts in STBY to a 
preset, much lower value in OPER, but I don't know if they can store and 
recall drive power levels by band and antenna

I too have the same issue.  I worked with Dick on this, but there is no
solution currently available when using an external antenna switch
(necessary with more than two antennas) with the KPA1500.  Unfortunately,
there is no way for the KPA1500 to tell the K3/K3S to use a different drive
level, even when using ANT1 and ANT2 on the same band, but with two
different antennas that require different tuning solutions.  

My (not yet implemented) initial solution is to use a macro for band changes
that will drop the drive level based on previously-determined data when
selecting a new band/antenna.  The long term solutions is a computer (Pi,
Arduino, PC, etc.) with the appropriate tables with the data entered from
empirical testing.  I only wish the ability (firmware and hardware) had been
included in the original design.

I'll take my KPA1500 to Lubbock next weekend for the CQ WW DX SSB Contest. 
I reconfigure the station's antenna switching to use ANT1 and ANT2 in the
KPA1500.  I carefully choose antennas by band so the two ports use the same
antennas by band and train the KPA1500 tuner appropriately.  The KPA1500 and
2x8 antenna switch follow the IC-7610 band and frequency data.  The hardest
part is prying the KPA1500 out of the station owner's hands so I can take it
back home!

Anyone with near perfect antenna systems (minimal tuning solutions needed)
won't have this problem.  Maybe I'll get there someday?  As Rosana
Rosanadana used to say:  "It's always something."  (not the same without
Gilda Radner voicing it!)

73, Bill, K8TE

P.S.  I have also noticed a big (300-400 Watts) difference in output after a
"long" pause in use (15-30 minutes) along with the difference between
antenna solutions on the two ports for the same frequency.

Your K3 stores the power settings. The amp reports when it goes in and out of OPER and the K3 (and K4) store two power settings per band, one for the amp in STBY, another for amp in OPER. You adjust these levels at the exciter, and they?re retained for recall on band switch and power off/on. Mine are typically 100w for amp in STBY and 25-35w for amp in OPER. I?m primarily a CW guy, but in digital modes I often drop down to see who I can reach with good antennas and little power.

There are K3 and K4 menu choices for ?Per band power? to enable this.

I see it as an issue only when using more than one antenna ON THE SAME 
BAND. I have two antennas for 30, 20, 15, and 10M, and three antennas 
for 160, 80, and 40M. My antenna switching system was developed for the 
KAT500. My long 6M Yagi goes to port #2.

Yes, that's unfortunate. I think Dick has done a great job with the 
tuner design, with it's capability to switch between multiple trained 
settings for every frequency!

No Joy yet.  Two list members made suggestions, i.e. ?Are the filters ?ON?, yes, and perhaps mis-plugged, but I don?t see how that could happen and still fasten them to the board.  Anyone have another idea?  I hesitate to open the rig up, as I have the sub-rcvr installed and my 80 year old fingers have problems inserting the cursed TMP plugs.

I have installed an additional 400Hz and 200Hz Filter in my main receiver.  When I switch them in line, they both act as if open.  I see the signal on my P3 (strong Russian!!) but no audio.   I have configured them correctly I believe.  Could both be defective?  I have set gain at 4db and 6db respectively, no change.

I'm active in ARES. My mobile radios are all Kenwood (that might change in the future if I go with KX2 for HF). Fortunately, all the front labels show up really well in red light. I use a really dim (dunno the lumens) light. I turn it on long enough to make changes to the radio, then turn it off. After reviewing recommendations here, I upgraded several of my lamps. "Low" power didn't mean really low in the past, and now I can get both low and red.

Princeton, one of my favorites, used to provide lifetime warranties, but I believe that all their products are now 5 years. I think that generally quality everywhere has seriously declined. OOH, with products getting upgraded all the time, maybe we should not care for some products. OTO, I don't want to go to use something and have it fail unexpected. That's why I keep more copies of some kinds of gear. I can say that my older Princeton TEC head lamps are not showing any wear. Very solid, but bulky, I admit, design. Unfortunately, not red, not dim enough.

They have a FRED model for 30USD that has pretty good reviews.

Didn't mean to post an ad for Princeton...I think that there are many good products available today.

The point is that I use red LEDs for a lot of night work, and wrt my radios, they all work well. I can't speak to many brands, however. But I suspect that they all use the same paint and display tech, so should all be fine. One point is that the kind of backlit LCD that can be turned off shows really well in red light, in my experience.

Bob,

I tried to email you directly, but it ?bounced.?

Are the filter Elecraft/Inrad made filters?

I doubt the 2 filters are bad if they are Elecraft sourced.? That would be the last to suspect. 

Make sure you have the MODE selected to receive that is enabled for the filter.

Else try this; Load the K3 Utility, and select the Filter Setup menu.

1) Make sure the main receiver is selected.
2) On the two filters you have installed, UN-CHECK all of selectins.
3) Click the ?APPLY? button.? The K3 should do a reset, and reboot.
4) Once the K3 has rebooted, RE-ENABLE the 2 filters you installed.? Should be for CW and DATA only.
5) Click ?APPLY? button.? The K3 should do a reset, and reboot.
6) Check operation of the 2 new filters.

If the above fails, repeat the above but DISABLE ALL filters then RE-ENABLE filter configuration as you desire.

I have a similar issue in that I cannot use the 2.8KHz filter for AM reception any longer since installing and enabling a 6KHz filter.

My Astatic Golden Eagle works great.  I used a 9v battery in the base. 
Never touched the mic element or volume control "slot".  No bias needed 
with the 9v Battery in use.  IIRC I used 45 for mic gain and 18 for 
compression or something close to that.  Always got great audio reports. 
  I may yet switch back to that mic.

It would be very nice if the KPA1500 would remember on a per band basis 
whether the mode was STBY or OPER the way it remember if the ATU is IN 
or BYP; to an outsider, this seems like not a big ask and it would make 
overdriving the amp easier to avoid as there are some bands I don't use 
it on...

Thanks for considering it & 73

Many hams are old with shaky hands and many also suffer from Parkinsons
(N6RA, KG6I, NI6T, N6BV, W2LE, ...).  It's far too easy to tap something
dangerous like this when it was not intended.  And what if your cat starts
swatting at the USB mouse and clicks Factory Reset?  :-)  OK, the latter is
unlikely, but the former is a serious concern.

By TUNE POWER I assume you mean the *TUNE LP* menu setting.  The *TUNE
LP* setting
now defaults to only 5W (used to be 10W).  So, using all the Elecraft
defaults, tapping the ATU TUNE button on the KPA1500 won't always work,
because the amp.'s tuner will only get 5W drive instead of 20W.

I just received the cable I ordered from Amazon to replace the one that came with the Bose QC-35 II headphones.  Made in China, not surprisingly, but has a 5', flexible, braided cover and comes with a screw-on 1/4" adaptor for the front panel headphone jack.  It came just in time before my cat ate through the very thin, OEM cable.

https://www.amazon.com/gp/product/B088CNY2VV/ref=ppx_od_dt_b_asin_title_s01?ie=UTF8&psc=1

Unlike my ancient Bose QC2 headphones, they work without turning them on, saving the rechargeable battery, when noise cancelling (or Bluetooth) isn't required.

They work great with my cell phone using Bluetooth too.

The rechargeable battery with noise cancelling on and Bluetooth off is rated at 40 hours.  It uses the same USB charging plug as my Logitech keyboard, so I have a charging cable on my desk.

I connect to my K3S with the cable, which is inadequate.  It's 4' long, lightweight, and flimsy.  The jack on the headphones is a sub-mini, 2.5mm, and the other end is a mini-phone plug, 3.5mm.  Amazon has several replacement cables that are heavier and designed for these headphones.

How about latency for CW either wired or wireless?

Lenny,

In my experience with over 1000 K2 repairs, I have never seen anything 
like that.  But I would look first at the PLL/VCO area, and possibility 
the BFO.

If you have a good monitor receiver, scan the signal at TP3 (near 12,000 
to 12,100 kHz) to see if the problem is present there.
Next would be the VFO at TP1 - the frequency will be determined by the 
band you are on - consult the VCO Table chart on the schematic Key page 
in the manual.

If all is well above, check the BFO at TP3 - you will have to set the 
menu CAL FCTR to get a signal there.

If all those are clean, then the problem has to be some sort of strange 
coupling somewhere in the transmit chain (or a failing component)

If it is in the VFO, add the VFO ALC change, if it is in the BFO, then 
add the K2BFOMDKT.

73,
Don W3FPR

Good Evening,

 ?? I took a walk today to find more wood.? After two weeks of rain the 
sunny weather coaxed out quite a few mushrooms.? The chanterelle 
population was high before the thinning.? I thought it would take a few 
more years before they came back.? The slash is rotting into the soil 
with many mushrooms pushing through.

 ?? The rain also cleaned the slate of tracks.? I found the latest elk 
paths while walking to my NW corner post.? It will take more rain before 
the intermittent stream there starts flowing.? Cedar like keeping their 
roots moist so they enjoy the channel.

 ?? SFU at 77.? It has been quite some time since it was this high.? 
Sunspot 2776 is not threatening, but rather, crackling with solar 
flares.? QSB will be interesting tomorrow.? It will be a fun test.

Subject: [Elecraft] KPA1500 / K3 Mystery
Message-ID: <390d01d6a553$065b1770$13114650$@gmail.com>

I made a recent change to the "Band Change-> STBY" setting on the KPA1500,
changing from NO to YES.  I did this to ensure the AMP doesn't have any wild
SWR or PWR spikes before the ATU has a chance to "remember" it's setting
after a band change.

 

Issue:  When switching the AMP from OPER to STBY, the K3 is supposed to
switch from the drive power setting (~25 watts) in OPER, to 100 watts in
STBY, it does not, it remains at the drive power setting.  I am 99% sure I
have all the cabling and settings set correctly in the K3 and KPA1500.  I
went through and manually reset the power settings on each band to let the
K3 and KPA1500 "re-learn" the change made, however, still no joy.

 

Jim, W6YA, and I have been going back and forth, however neither of us have
had any luck.

 

Do you KPA1500/K3 owners out there have any ideas or suggestions?

I took a chance on the QC-35 while on sale and so far I'm pleased. I also
bought an accessory boom mike that plugs into the connector on the QC-35
and so far that has worked well in OTA tests. My QC-15 no longer attenuates
my KPA1500 fans beyond just covering my ears with the cups so something has
gone wrong with those. The QC-35 are very effective. I use a ModMic with
the QC-15 which works very well and may substitute for the accessory mike
if that doesn't pan out.

The boom mike came with a much more rugged cable than the one which came
with the QC-35. I was concerned about the mike moving but with the shirt
clip I find it stays in place to my satisfaction. I don't know if it will
reject amp fan noise however. I'll have to try that today. The fan never
gets above speed 2 on SSB so not much of a challenge. The boom mike came
with a TRRS to dual TRS splitter which worked well on the back on my K3s.

The QC35 claims 40hrs of battery life when wired which is far more time
than I'll ever put in any contest so that isn't a concern. When unplugged
it becomes a Bluetooth set which I've paired with both my phone and PC.
That means that I no longer need a PC headset cluttering up my desk.for
when I want to do MorseRunner or listen to a Youtube session.

73 and stay safe!

Just did an OTA test and Fan Speed 2 was inaudible but Fan speed 3 could be
easily heard. But since I've never seen Fan 3 in an SSB environment that I
can remember I think this will do. Obviously other shack noise similar to
FS3 would also be an issue but that never happens here. M/M environments
may not work.

I'll run a test later with my ModMic to see how that fares vs fan speed
setting for comparison.

There is a required K3 enabling menu selection, something like per band power setting. It?s the same menu item that allows you to dial 20 watts for 20 meters, 30 watts for 30 meters, and have those choices retained as you move from band to band.

The amp status messages go over AUXBUS, a wire in the 15-pin ACC cable.  Is that OK? Does the K3 VFO frequency show up in the KPA1500 XCVR FREQ status screen as the VFO is moved? That K3 VFO frequency info flows over the same AUXBUS wire.

YES, when switching the KPA1500 between OPER and STBY, the K3 displays the
messages "KPA500 OPERATE" and "KPA500 STANDBY", depending.

 

YES, the K3 is set CONFIG: POWER SET is Per Band.

 

YES, when in STBY on the KPA1500, I set the "no amp" power to 100 watts, and
when in OPER, I set drive level per band; usually less than 30 watts, which
gets close to the legal limit.

 

Still the same results as described below.

I made a recent change to the "Band Change-> STBY" setting on the KPA1500,
changing from NO to YES.  I did this to ensure the AMP doesn't have any wild
SWR or PWR spikes before the ATU has a chance to "remember" it's setting
after a band change.

 

Issue:  When switching the AMP from OPER to STBY, the K3 is supposed to
switch from the drive power setting (~25 watts) in OPER, to 100 watts in
STBY, it does not, it remains at the drive power setting.  I am 99% sure I
have all the cabling and settings set correctly in the K3 and KPA1500.  I
went through and manually reset the power settings on each band to let the
K3 and KPA1500 "re-learn" the change made, however, still no joy.

 

Jim, W6YA, and I have been going back and forth, however neither of us have
had any luck.

 

Do you KPA1500/K3 owners out there have any ideas or suggestions?

Might you have set the Normal power for the band to low power? There are two power levels, after all. We tend to pay attention to the low power setting for the KPA usage, but it is also quite possible to set the Normal (KPA on STBY) to a low level as well. That would get the effect you see.

Bruce

My system works? with no issues.

I originally had some problems due to external software and macros I had 
created that used the PC command to set power for different modes.? The 
K3 stores the last power used per band when either in OP or STBY with 
the KPA1500, if you are getting the messages showing that the K3 
recognizes the change in KPA operating mode then my only question is are 
you using any software or have macros that might be changing power 
without you knowing. I had to take all the PC commands out of my macros 
for safety.

If all you say is correct (not doubting) and you are getting the 
messages, not using any software or macros then only suggestion is to 
contact support.

Like K5MWR, my K3 & KPA1500 work correctly with the K3 going to the alternate power setting when the 1500 is switched in Standby.

K3: Firmware 5.67  Power Set per Band; Tuning power Normal.

KPA1500: Firmware 2.38  Band Change Standby = No.

Neither unit is connected to a computer for any control functions. The sole connection is an outboard analog to USB interface for the digi modes.

I'm open to checking any other settings that might illuminate.

Subject: [Elecraft] K3 band data query
Message-ID: <A0B732C8-008E-4BAA-8D45-928F3CCBEF76@gmail.com>

I operate a vertical antenna for 80 & 160M where the bandwidth is such that I need to switch in reactance between the phone and CW portions of each band. I currently do this manually, but am installing vacuum relays for switching remotely. Is there a way the K3, through the data port or whatever, can send a signal when migrating between traditional (or operator defined) phone and CW portions of the band?

Antenna matched points on 160 are at 1825 and 1855; 80M are 3520 and 3800.

I had considered sensing the K3 mode, but that?s not an acceptable solution. The 160M CW contests can often extend into the traditional phone area and FT8/WSPR often use USB mode in the CW portion.

Thoughts?

Just shortly before you posted this, Kevin posted that the 40M 
CW net was a 0045z on Monday (Sunday evening for those of us in 
the US.) Also the frequencies he posted are: 14050 kHz. 
and?7047 kHz.

Dennis,

Frequency data is available from the RS-232 data, but needs decoding 
which implies that a smart device is needed (computer).  See the K3 
Programmer's Reference Manual for the commands and responses.

Bruce,

What is the firmware version of your KPA1500?  2.48 is the latest.  There
was also a change in version 2.38, almost a year ago, that could fix the
issue for you:

02.38 11/4/2019 (Production 12/3/2019)
? Switch to STBY if BAND CHANGE->STBY is enabled and the frequency (from
XCVR or TX count) is below the amp's frequency range
? Wait longer after band change to inform K3 that KPA1500 has switched to
STBY when BANDCHANGE->STBY is YES

This is easy to do with an Arduino if you are capable with those kind of things.  The serial port on the Arduino can read the data from the K3, and set/clear a relay at any frequency you want.  Some assembly required.  :^)

Message-ID: <965c877a-fc07-c7eb-311b-71f885caa400@mindspring.com>

Hi,

My KPA1500 just started needing a lot more drive (2X) to get 'normal' 
output.  I normally need 25-30 watts drive to get ~1k out.  Now I need 
about 60W.  I get two kinds of alarms, depending on how I test the 
situation, either a red "Gain Low' or a yellow 'Input Pwr'.  If I drive 
with a steady 10w, I get a 'Gain Low'.  On cw, Just before cutting out, 
I can drive the amp with ~65w, get ~600w out, then get 'InputPwr" 
followed by Gain Low' and the amp cuts out.

Time to go back to the factory?

Tnx, Frank W2YK

Key Out to PTT on the amp. Do NOT use ALC -- it's a recipe for splatter 
and clicks. Always set amp power by adjusting power out on the transceiver.

Bruce, I remember that one time I redid all my tuner settings on each 
band and the STBY power was then reduced to the same value as the drive 
power.? I had to set each band back to 100w in STBY.? That solved the 
problem. Check it out.? It's a per-band setting.? 73, Jim W6YA

That depends a LOT on the amp. I'd RTFM for the amp before setting that 
much delay, which is usually limited by antenna TR switching. TenTec 
made one (maybe the first) solid state ham amp, and all of their amps 
used vacuum relays for antenna switching. They switched in less than 8 
msec. K4XU, designer of TenTec's tube amps later worked for Alpha. The 
86 and 87A were the last he did for them. They used diode switching, 
which is very fast. And in bar conversation, he made a point of saying 
that he designed the RF section, not the control circuitry.

I operated two of his TenTec Titan 425, bought used (their first legal 
limit tube amp) in my station for about 12 years of heavy contesting, 
until my purse got heavy enough to replace them with a pair of used 
87As, and this past summer, one of the 87As became a spare for a KPA1500 
(so I could get legal limit on 6M). Elecraft amps also use diode 
switching for antennas.

I did an initial test of this headset yesterday and found that the audio
quality was good, but there was some background hiss. It could have been
because the headset was not properly powered, since I have it plugged in to
my mixer with phantom to 2.5v jerry rigged. I have a proper adapter coming
tomorrow, and will do some proper analytics and comparison to other mics.

I took a chance on the QC-35 while on sale and so far I'm pleased. I also
bought an accessory boom mike that plugs into the connector on the QC-35 and
so far that has worked well in OTA tests. My QC-15 no longer attenuates my
KPA1500 fans beyond just covering my ears with the cups so something has
gone wrong with those. The QC-35 are very effective. I use a ModMic with the
QC-15 which works very well and may substitute for the accessory mike if
that doesn't pan out.

The boom mike came with a much more rugged cable than the one which came
with the QC-35. I was concerned about the mike moving but with the shirt
clip I find it stays in place to my satisfaction. I don't know if it will
reject amp fan noise however. I'll have to try that today. The fan never
gets above speed 2 on SSB so not much of a challenge. The boom mike came
with a TRRS to dual TRS splitter which worked well on the back on my K3s.

The QC35 claims 40hrs of battery life when wired which is far more time than
I'll ever put in any contest so that isn't a concern. When unplugged it
becomes a Bluetooth set which I've paired with both my phone and PC.
That means that I no longer need a PC headset cluttering up my desk.for when
I want to do MorseRunner or listen to a Youtube session.

73 and stay safe!

Ben, The process I use is to first clear all the tuner settings on the 
band I'm using.? I go to STBY and hit ATU TUNE.? Low power is applied to 
start the search.? When I first got the amp I did this when in OPER, but 
even with low drive power I kept getting faults due to initially high 
SWR.? Recently during a trace working with Dick he noticed intervals of 
very high drive power... up to 60w, which means the K3 ramps up power 
output at times.? It's complex.? Jim W6YA

Dennis,

The K3's BCD outputs are defined by band, not frequency. You need something that tracks QRG, but the following may be serious overkill for your needs...

If you use the general purpose logger DXLabs, or the contest logger N1MM, consider a freeware Band Decoder called FreqEZ. The program receives frequency info from those loggers and allows you to to define 255 band segments that control any combination of 16 remote relay lines. The software is free, but the hardware components are not. The FreqEZ website describes a DIY solution or an Assembled and Tested solution. (DISCLAIMER: I wrote the free software, but I also sell the Assembled and Tested hardware)

www.freqez.info

If you only need a few outputs, you could probably cobble together something that uses the free software but is simpler and cheaper. Contact me if you're interested.

I can't find the link to the last versions of firmware & software for the
K2. 

I know it was some years ago, but thought it would still be available on the
Elecraft site.

Does anybody have a link or can tell me the Version numbers?

Ray,

I don't know about any software, but the latest firmware is available - 
the most recent is MCU 2.04, IOC 1.09  They must go together - order as 
FWK2MCIO.  If you have trouble finding it on the website, just email 
sales at elecraft.com to order.

To find your currently installed K2 firmware level, hold any button 
while powering the K2 on, the firmware level will be briefly displayed.

73,
Don W3FPR

Message-ID: <005701d6a673$d4b6adc0$7e240940$@gmail.com>

Looking for details from anyone who resolved issues with excessive
transformer hum during transmit on a KPA-500. 

 

I have a hum mitigation application note sent from Elecraft tech support.
But the procedure recommended is pretty involved - removing front/side
panels, un-plugging connections, removing the transformer, changing
positions of the rubber discs, and putting it back together. Possibly more
than once, depending on the results. 

 

There is a risk of breaking something, and I'm not sure its going to solve
the problem if I'm successful. This is a new out of the box KPA500 kit.

 

If anybody has any lessons learned I would appreciate hearing them.

 

Jim, N4KH

I don't see the problem. I presume you bought a kit to assemble it 
yourself. You simply reverse part of the assembly procedure, then 
re-assemble it. I've assembled several KPA500s and I'd bet that you 
didn't quite get it right first time. There's no shame in that. This is 
a risk you take with self-assembly. ISTR there's a torque wrench setting 
for tightening. Did you use one?

Have confidence. Take it apart, do as they say and enjoy feeling smug 
that you fixed it yourself. :-)

Lessons learned? Yeah, take your time, follow instructions to the 
letter. Don't do anything if you're tired. Plenty of space. Plenty of 
light. The right tools and a suitable container for parts.

Alan. G4GNX

"If anybody has any lessons learned I would appreciate hearing them."

I built a KPA500 kit and I too was bothered by the transformer hum. I learned that Elecraft has used several different transformer suppliers and that transformer sizes vary. This means the clearances between the transformer and the case may be very different for the supplied transformer than as shown in the manual. I carefully shimmed the transformer before tightening the retaining nut so there was no case contact.

I also learned that hum level is directly related to PA current. If the PA load is mismatched the efficiency goes down, PA current is higher for same power output, and hum level is higher. I ignore the 1.5:1 match is ok recommendations and tune for better than 1.2:1.

Perhaps the most important thing I learned is that one can get used to almost anything. The hum and clicks that drove me crazy in the first few months of ownership are now ignored. I found something else to worry about.

Hi Jim,

I had a bad hum from my KPA500 kit, an early model.  Elecraft sent me a new
center bolt that was only threaded on the end--the original bolt had
threads all along the shaft.  Also an additional pad.

Assuming you assembled it all correctly, try these two things:  If you have
a torque wrench, tighten the bolt to the exact spec.  If you don't have
one, try slightly tightening or even loosening the bolt.  Second, make sure
the transformer is exactly centered on the bolt and not touching any of the
sheet metal, including the side panel.  Use a strong flashlight to check it
with the top removed.  UNPLUG THE AMP FIRST!

Mine has been hum-free for years, after the tweaking.

When the KPA500 first came out, there were lots of complaints about hum.
This made it difficult for Elecraft Support to differentiate between normal
hum, which I can barely hear, to the obnoxiously loud hum of a misaligned
transformer.  I finally called support so they could hear the hum of my
KPA500, which was in the obnoxious category.

Take a breath, you can fix this.  Tweaking the bolt torque, and slightly
moving the transformer, requires only removing the cover.  If you don't own
and can't borrow a torque wrench, given your investment--buy one.  A small,
inexpensive one will do the trick as the torque is quite low.

Even the 'normal' hum was too much my tastes. My KPA500 is now on the floor, under the desk with a remote digital readout on the desk.

Toroidal transformers cause very little acoustic hum, unless the core
is not tightly wound or the copper wire windings are loose!

If you have to tighten the mounting bolt with a torque wrench
to get the transformer quiet, something is wrong!

Is there any harm in leaving the KPA500 rear MAIN Power Switch ?ON', 24/7/365? (not the front panel power button).

I have done that with my KPA500 at the home station with no problem, but wondered about doing it at the remote site? I can operate the front panel ?ON? button and ?OPER/STBY? switch remotely so the amp is not running full-time, just the internal power supply.

If you leave it "on," the power supply is energized.  A surge on the 
line could fry the unit.  It happened to me with a Yaesu Quadra.

The torque spec is called out in the manual.  Why not use a torque wrench?
Can we please not resurrect the KPA500 hum thread already beat to death
multiple times years ago?  Or does everyone need to chime in yet again?

55 inch-pounds.

Ray,

I don't know about any software, but the latest firmware is available - the most recent is MCU 2.04, IOC 1.09  They must go together - order as FWK2MCIO.  If you have trouble finding it on the website, just email sales at elecraft.com to order.

To find your currently installed K2 firmware level, hold any button while powering the K2 on, the firmware level will be briefly displayed.

Then perhaps someone needs to educate Elecraft not to specify use of a

Message-ID: <CAG4eVbXj_doxquEpPxuFkRcwVOWBNR=TCyEt3LmMLi0dg95-7g@mail.gmail.com>

In a K3S tested with two Alpha 87a amps using RF sensing to change band and
tuning the K3S appears to easily trip the amp into Fault mode. When amp is
cycled between Operate and Standby to clear the Fault, K3s can no longer
key the amp unless you cycle power to the radio. Then it works properly
again.

1. Manually change bands on the radio, with amp still sitting on prior band
and with the drive turned down to 5 to 8 W to try to ensure we won't trip
the amp while possibly transmitting into a momentarily high SWR of the
wrong band input circuitry? When keyed on the new band to have the amp
auto-tune it trips into Fault.
2. After cycling the amp from Standby back to Operate the K3S can no longer
key the amp. It is transmitting in apparent bypass mode as indicated by the
low RF level still indicating on the built in Watt meter of the amp.
3. This was tested with two 87a amps. Same issue.
4. Pulling the key line and shorting RCA plug at radio end does
successfully key the amp.
5. Another K3 radio with updated syn) doesn't do this.
6. I believe the pertinent default settings of the two radios were set to
be the same, though perhaps the band by band default drive setting or limit
may not have been mapped (If I understand correctly).

I am the new owner of the K3S and I have zero experience with the radio or
type. I've not set up my station yet (working on rebuilding tower and
antennas) since buying the radio.  It is about 3 years old but only used
for 6 months by the prior owner and once by my group at last year's Field
Day. The radio and P3 are being loaned to a friend to use in an SO2R entry
in a contest.

Has anyone experienced this? Any ideas on what may be wrong?
Can my K3S be sending a spike of power, anyway, to cause the trip? We
haven't gotten further into verifying this or other things as we only
started this today.Thank you for any help you may provide.

Hi John,
Both my KPA500 and KPA1500 are on a shelf in the basement, literally right under my feet. The last time I shut them off was when I went to KP2M last February.
If the power switch isn't on I can't tun them on from Elecraft's remote software.

Is there any harm in leaving the KPA500 rear MAIN Power Switch ?ON', 24/7/365? (not the front panel power button).

I have done that with my KPA500 at the home station with no problem, but wondered about doing it at the remote site? I can operate the front panel ?ON? button and ?OPER/STBY? switch remotely so the amp is not running full-time, just the internal power supply.

I have been looking into remote switches. While I have not settled on anything, I am looking at remote controlled high power handling relays. Not saying that they are needed in this situation, but they are an option. Then you could leave the power switches on, close the relay, and use remote software to turn them on. If you are remote already, you prolly have the capability.

Hi Jack,
I've had both my KAT500 and KPA500 powered on 24/7 for the last several
years, as I operate them remotely from my second home in Texas.  The
KPA500's AC power is connected through a dedicated line, surge protector
and battery backup.  The KAT500, which is DC powered, is connected to an
Astron RS-35M, which is on a dedicated line, surge protector and battery
backup.

As Tony, N2TK, stated, they need to be powered on if wanting to run
remotely.

Message-ID: <CBEC1240-BA62-47B9-B6F3-BA6EB822F912@me.com>

Dear Elecrafters,

   I have a K3 with an internal 2m transverter that I use with an external amp.  Initially I had the amp connected to PTT-out but that would key the 2m amp if I transmitted on any band.  To help with this, I put the optional jumper on P8 in the transverter so that it put out 5v on ant3 (2m out) while transmitting.  I then built a simple NPN grounded emitter circuit to key the 2m amp by grounding its PTT-in when 5v show up on output of the transverter.  Here is the shocker:  5v show up on 2m transverter out whenever I transmit on ANY band.  How disappointing.  Am I missing something?  Is there a simple fix?

Kimo,

In order to keep my 87a from tripping into fault on band change, I sometimes
need to lower the drive power. About 10w seems ideal.

On my 6700 and 890s I am able to configure a low drive power for the TUNE
function. I'm not sure but think the K3 has a similar function. Of course
make sure the antenna is matched before TUNE is activated.

Carlos...

The numerical values associated with the K2 filter settings are 
approximations, used mostly for reference when adjusting the filters. 
They do not indicate the "exact" filter bandwidths, etc.

Aligning the K2 filters is best accomplished following the instructions 
on Don Wihelm's site, http://www.w3fpr.com/. Look at the bottom of the 
main page for "K2 Filter Alignment." Don is an expert authority on the 
K2, and his instructions are just about the standard for aligning the 
filters.

Torque wrenches are used for two reasons:

1) to make sure things are tight enough

2) to make sure things are not tightened too much.

Stating the proper torque is good engineering practice.  For common screws and bolts one can find the suggested torque in reference books and online.  For special circumstances the manufacturer should publish the proper values.

Carlos,

If you change the filter width, you will also have to change the BFO 
settings to keep the passband centered at your desired sidetone pitch.

Jim.

I don't see this as resurrecting an old thread. You've asked for help in 
your particular circumstance, not to discuss the merits of a generic 
transformer.

As you seem to have done almost everything sensible, if the correct 
torque doesn't correct it, I think your only recourse is to get back on 
to Elecraft and tell them you think the transformer's faulty.

In the meantime, I guess the only thing you can do is either not use it, 
or wear headphones and try to ignore it.

73,

Alan. G4GNX

Raj...
I have the same issue, but a less elegant solution.  My 2 Meter amplifier
has a remote head that has the keying input located on the back of it.  I
opened it up and wired a toggle switch in line with the circuit with an LED.
I labeled it STBY/OPR like on my Ameritron AL-1200.  I just flip the 2 meter
amp "out" of the PTT circuit when I'm not using it.

Thanks,

Dear Elecrafters,

   I have a K3 with an internal 2m transverter that I use with an external
amp.  Initially I had the amp connected to PTT-out but that would key the 2m
amp if I transmitted on any band.  To help with this, I put the optional
jumper on P8 in the transverter so that it put out 5v on ant3 (2m out) while
transmitting.  I then built a simple NPN grounded emitter circuit to key the
2m amp by grounding its PTT-in when 5v show up on output of the transverter.
Here is the shocker:  5v show up on 2m transverter out whenever I transmit
on ANY band.  How disappointing.  Am I missing something?  Is there a simple
fix?

Raj, N2RD

Nice solution.

Unfortunately for me, I am trying to operate remotely.  I may just have to get a web switch and turn the amp on and off.  I am hoping that some one has a better solution.

Jim,

If your KPA500 is older, there was a change to the transformer mounting 
which added a couple washers to the assembly - both under and above the 
transformer.  Contact support at elecraft.com for details and availability 
of the kit.

Despite having the correct settings, I have not been receiving my own posts, and, because I use a client email aggregator, not the web, I don't know if my posts make.

I contacted the listmaster. The reply was to the effect that sometimes it happens, and we don't know why.

So I am running 2 tests
- originate a post
- reply to a post

Rich,

In my experience, this is a ?feature? of gmail. Apparently they assume that you should not receive a copy of your own posts.  I went through this same exercise a while back.  Didn?t find a solution.  I just assume my posts make it and they seemingly do. 

73,
David - N5DCH

I ran these tests --- have not logged in to see what messages were received, but one person replied to the msg off list, so it got through

originated an email to the list - got my own post back, and got a bounce msg, too, because I asked for both

replied to a post sent to me personally, but in reply to my list post - got the bounce, but not the msg

replied to a post from someone else about a different matter - got the bounce, but not the msg

replied to my own message, in the once case where I received it from the list  - got the bounce, but not the msg


Because this list is different, at least for me, when I reply, I usually don't get elecraft as the addressee, I get others. Sometimes elecraft shows up in the CC place. So my habit now is to "reply all" which captures all the addressees. I then delete the individuals, unless I specifically want to sent there, and replace all the addressees with one address, the elecraft mailman address. That ensures that I am sending back to the list, which is what I want to do most of the time. It seems to work.

As you can see from above, if I originate a message, I get it from the list server, but if I reply, I don't. Does this have summat to do with the way email headers are formed, and what mailman is using to determine the potential list of addressees? So even though I replied, my email address is not attached to a header that mailman uses to determine who gets the replies? If I originate, there are no other email addresses in the headers, so I /have/ to show up in the right header, but if I reply...?

I vaguely understand this...that is, I completely get your point, but not sure what gmail does...

nonetheless...I did get a copy of an email I originated in gmail, which seems to imply that this is not a gmail issue. That is, why would gmail decide that it is OK to send me a post from the list that I originated, but not OK to send me one that is a reply to one from the list?

You can enable a Gmail setting on your account to cc or bcc you on every message you send. Of course this doesn't indicate if the forum received and posted your message but you would have a copy of what you sent.You can log onto the forum website to check if your message was received in case you don't see it included in the subsequent thread. If it is not there you can resend it from your Gmail "Sent" folder.?Ken?WA2LBI?LG G6?------ Original message------From: David HerringDate: Tue, Oct 20, 2020 12:52To: Rich NE1EE;Cc: Elecraft at mailman.qth.net;Subject:Re: [Elecraft] acknowledgement of post testRich,

Maybe a web controlled appliance plug?  I have one that operates a
dehumidifier that I can operate with an app on my iPhone.  Use something
like that that has a relay inside - just wire it up for your amp main.

Nice solution.

 

Unfortunately for me, I am trying to operate remotely.  I may just have to
get a web switch and turn the amp on and off.  I am hoping that some one has

Subject: [Elecraft] 2m internal transverter PTT out

Dear Elecrafters,

  I have a K3 with an internal 2m transverter that I use with an external
amp.  Initially I had the amp connected to PTT-out but that would key the 2m
amp if I transmitted on any band.  To help with this, I put the optional
jumper on P8 in the transverter so that it put out 5v on ant3 (2m out) while
transmitting.  I then built a simple NPN grounded emitter circuit to key the
2m amp by grounding its PTT-in when 5v show up on output of the transverter.
Here is the shocker:  5v show up on 2m transverter out whenever I transmit
on ANY band.  How disappointing.  Am I missing something?  Is there a simple
fix?

Raj, N2RD

Raj,

There are two ways to deal with this.

First you can use DIGOUT1 to key an external relay which controls where the
common PTT goes, either to an HF amp or a 2m amp. In the menu, set DIGOUT1
to on for 2m only. A small, low current 12v relay connected between 12VDC
and pin 11 on the 15pin HD connector on the back. Let the common of the
relay go to the PTT jack, NC to your HF amp and NO to your 2m amp.

Second is DIGOUT0 which when KIO3 is set to TRN or HF-TRN goes low when you
select a transverter band (anything about 6m). This could also key a small
12v relay to steer PTT the proper direction. As above.

Hope this helps.

Gmail is doing that for you.  They do you the "favor" of not repeating 
what you sent.  Several folks have posted questions about that behavior.

I have the older style thick heavy cable from Elecraft for connection

application. What is the best way to extend its length without  any pin

For a couple of years, I have had two 87As on my operating desk, each 
driven by a K3, and I the only time I experienced any issues when 
changing bands was when I screwed up and transmitted into the wrong 
antenna.Both of those 87As have the auto-tuning feature, which was added 
several years after the amp was introduced. Not all 87As have it, older 
amps require the replacement of a PROM, and after the company has been 
sold several times, it's no longer available.

The auto-tuning system must be trained, by band segment. It's covered in 
the manual, which can be downloaded. That training can be tricky, 
depending on what the previous owner might have done. And the feature 
must be turned on, by simultaneously pushing two of the buttons. I found 
that it works quite well when working into reasonably well matched 
loads, but its tuning range is pretty limited, and falls apart as the 
mismatch approaches 2:1. It's a Pi-L output network, not an antenna 
tuner.

One of those 87As has been replaced by a KPA1500, and it DOES 
occasionally go into Fault mode when changing bands, but it matches a 
FAR greater range of loads. I didn't replace the 87A because I was 
unhappy with it, but to get legal limit on 6M.

The VGA cables are no good. Although they have 15 pins on each side, many are not through wired.  Many important pins are not connected at all, and some are shorted inside.

FS is my last W2-A with two of the 2w to 2kW sampling heads.  All unused.  Documentation is on "E-on-line".

No cables.  Use your own choice of RG8, RG8x or RG-58.  Price through Elecraft is $379 plus 179 plus your tax & shipping.

Will sell total package for $395 plus $8 USPS to upper-48.  You save approximately $240.

QSL to purchase.

Set the "band Outputs" correctly (page 19 of the K3 Owners Manual) and
build a discrete logic (TTL/CMOS) band decoder to select PTT to the
2 meter or HF/6m amplifier.

Alternatively, get a band decoder that works on the frequency data
from CAT/RS232 (like microHAM Station Master) and allow it to select
PTT to the 2 meter on HF?6m amplifier based on the CAT data.

Besides, I've been a member of this list since at least 2008 and I can 
recall many KPA500 owners still complaining about hum even after trying 
to follow all of the advice given here.? It's still a valid topic and 
not outside the list boundary rules.

And of course, every single post in this recent KPA500 hum thread has 
been clearly identified in the headline and could be easily ignored or 
deleted by anyone who was able to read it.? You could have done so 
yourself in far less time than it took you to write your post.

 No,  no. The torque wrench is used to insure the proper torque is applied. 

A torque wrench is not a torque multiplier, it is a measurement instrument.

to follow all of the advice given here.? It's still a valid topic and 
not outside the list boundary rules.

And of course, every single post in this recent KPA500 hum thread has 
been clearly identified in the headline and could be easily ignored or 
deleted by anyone who was able to read it.? You could have done so 
yourself in far less time than it took you to write your post.

Yes. 100% of the time I?ve specified using a calibrated torque wrench or driver in an assembly procedure is to prevent *too much* torque from being applied.

In a post long ago, 2 meters was posted by Elecraft, as the max end-end 
length of the ACC cabling (two sections of stock cable).? Cabling longer 
than that /MAY /affect the signal timing, causing errors (their words).? 
I ran my temporary station that way (for a couple years) until I got the 
new shack room built and had no issues with cabling.

The cost of the proper cable from Elecraft is reasonable or there are 
other sources (at your own risk).? You bought a Ferrari of a radio, are 
you going to cripple it with questionable tires?? Don't cheap out, do it 
right.

I also agree, the N6TV boxes (and cables) simplify the wiring (not 
neaten to any great extent but it helps, it's great but not miraculous 
:-P) .? If you go that route, Bob will work with you for the proper 
pieces based on your needs.? Neatness helps minimize noise and other 
issues too.

Subject: [Elecraft] 2m internal transverter PTT out
Message-ID: <22.9B.15385.53B4F8F5@smtp04.aqua.bos.sync.lan>

This is disappointing news.  I just purchased a K3S-10 to use mainly as a uWave IF.

I looked at the K144XV and KXV3B schematics.  The fix will need to be implemented on the KXV3B.

The K144XV uController monitors the 7R voltage from the baseboard, that is routed through KXV3B, and when this voltage is 0, the 5R voltage is turned off, and 5T ON, sending +5V out the BNC if it is strapped in.  There is not a way for the K144XV to determine the transition out of the RX to the TX state was NOT intended for it.  So the K144XV is being cycled RX/TX, enabled or not.

I have determined a fix that would require 1 trace cut, 2 diodes, and 2 resistors, and 4 connections on the KXV3B.  It is rather simple in circuit design concept, but may be physically difficult to implement.  Possibly with SMT components and a very small PCB.  I do not know how much room is available, or if the trace cut mentioned can be made.

Gee Alan, we get told that all the time, specially by coworkers? <GRIN>

As for the transformer, the tech support guys give good advice here. Place the rubber disks below the transformer in the appropriate places, and one above as the instructions indicate.
Essentially you want to get the transformer off the base chassis enough to keep it from vibrating against it. We all worry about tightening the nut down too much, which is why we added the torque wrench suggestion in the manual. But it does need to be rather tight to keep things from vibrating. Also, make sure all the screws in the chassis are tight. The hum can come from other parts as well. Making sure thins like the rectifier board are properly tight can help alleviate this situation also.

Someone asked about keeping the rear-panel power on. I have the first KPA500 still in operation, and it has seen very little rear-panel off time during its life. In this situation, the power supply is on, and the microcontroller is on in sleep mode. This means the unit does draw current, but not very much. I have seen no effect from it on my power bill. During months when I participate in contests I can?t say that - running 500 or so watts for long periods each weekend does spin the power meter a bit.

Thanks for the compliment, we work very hard to create, build and support products that make you guys happy. I think it shows.

73!

Bruce;

Did you ever resolve the issue?

The KPA500 and KPA1500 send events to the K3, not commands. The distinction is important - an event simply reports a state change in the amplifier. It is up to the K3 to decide what to do in response, if anything.
Thus when tapping a and button the KPA simply sends an event indicate that the button had been tapped, the K3 receives that and decides to do a band switch (if needed).
The fact that the K3 is indicating a response (in the VFO B display) says the K3 is indeed receiving the event properly. That means the KPA1500 is working properly, so the issue is in the K3.

Since the K3 sets the correct power for the KPA OP mode, it should be expected the the K3 is also selecting the high power setting when the KPA indicates that it is in STBY mode. The is the same power level that would be used if the K3 is powered up with the KPA left turned off. From personal experience I have many times found the power not to be what I expected after some special operating activity, like Field Day where we run just 5 watts. Turning the Power knob usually fixes the problem quite nicely.

I'll second Jack's observation Bruce.? "Most" of the time, the K3 
switches power levels properly ... but, the key lies in Jack's 
description of how it works.? The K3 gets notice of "events" from the 
KPA which treats the notices as "fire and forget."? The event causes the 
K3 to take some action(s) and go to some state.? It seems to be great at 
that. It also needs to remember that state [conceptually, "KPA in 
standby"] regardless of what goes on thereafter.? It seems there are 
things you can do after putting the KPA in off or standby that foul up 
this state memory.? With a background in aircraft systems for the 
military, the peripheral fire and forget mode is a non-starter for me.? 
I just developed the habit of always checking the K3 PWR OUT setting 
before transmitting.

3.	MOXA NPort 6450 4 port serial server (over IP) in pristine

ports in a remote location.  $100  

I think the new price is $499. https://www.neteon.net/moxa-nport-6450

All the discussion of Y-Boxes and S-Boxes prompted this email as I?m still clearing items surplus to my needs:

 

1.	N6TV S-Box in pristine condition and acquired in 2018.  Jumpered and labeled for an ACOM 2000A and RemoteRig RC-1216H setup.  $60
2.	N6TV Y-Box in pristine condition and acquired in 2018.  Jumpered and labeled for K3/K3S ACC to AMP AUX.  $60
3.	MOXA NPort 6450 4 port serial server (over IP) in pristine condition.  This is really a neat piece of equipment if you need 4 serial ports in a remote location.  $100  

I think the new price is $499. https://www.neteon.net/moxa-nport-6450

	(added by postmaster@btinternet.com)

I have just got a secondhand K2 # 5835 and find that the RF Gain pot needs replacing. The component is available from Elecraft but the shipping cost to the UK and the likely long delay means that I would prefer to source this here or in Europe from Mouser UK or similar supplier if possible.
I know it?s a 5K linear pot but does anyone know a Mouser part number or other supplier please?
Would it be a good idea to replace the 3 other identical pots at the same time?
Similarly does anyone know the Mouser part number for the 5K audio taper AF Gain pot?

Hello while I wait for feedback from the (no doubt overwhelmed) Elecraft support I thought that I would ask the group about a problem that I have with my K3S.

When I run JT65B and even to a lesser extent FT8 I see unacceptable amplitude variation on both the 6m output and the transverter output (on 28MHz). If I put my E4406 Spectrum analyser on peak hold with a narrow span and 10Hz RBW I see amplitude variations of a little over 1dB on the modulation tones across the passband.

To save time.


  1.  On the ALC meter I have 4 bars lit up with the 5th occasionally flickering - the audio drive level is correct; it is not an ALC issue
  2.  I calibrated the TX drive - the effect is observed at 1mw, 5W, 50W and 100W on 6m.
  3.  I am using DATA A so no TX EQ or compression
  4.  The audio has from WSJT-X been measured on a UPV audio analyser and there is less than 0.1dB variation when using a UMC404HD sound card
  5.  The effect is observed with both Line input drive and the UMC404HD soundcard and the internal K3S codec
  6.  My old TS2000X does not exhibit more than 0.1dB amplitude variation with the same sound card providing audio and the same test setup
  7.  I have verified the amplitude variations at RF with a diode detector and an oscilloscope
  8.  The effect is clearly visible on several power meters
  9.  This AM causes some spectral re-growth, although this is tolerable

So given all that I am beginning to wonder if the problem is due to filter ripple in the standard K3S 2.7kHz filter? I cannot think of anything else. I was considering buying an Inrad #718 filter.

This is very critical for EME when signals are weak at the RX side, if you have amplitude variations and you are at the threshold of detection at the receiving station this can cause decodes to fail. This is more important on 6m EME than 2m where I have more margin.

I think that this will be quite common, has anybody else got a K3S and the equipment to check and verify my observations?

Conrad, 

My friend just had the issue you described with a different brand radio. He was transmitting near the high end of the TX filter and on higher tones of the FT8 the power would drop causing the TX power to waiver. 

The fix for him was to enable Fake It in the WSJT-X radio settings tab. That keeps the TX audio centered between 1 kHz and 2 kHz. Well within the TX filter bandwidth.

I have a K3 and a K3S at my Caribbean station... I see the same behavior on
my K3S but not on the K3.  I've calibrated it several times but have not
diagnosed it past that.  I've seen the power vary by as much as 50% at
times.

My K3 doing the same variation. Now I am running my K3, at 70% bellow 
100 watts so it will not push above the limit like I did with my KPA500. 
My KPA500 is back at the Elecraft hospital.

Many years ago, when I replaced stock 2.7kHz filters with 2.8 kHz 
filters in both my rigs, it significantly reduced the incidental AM I 
was seeing on RTTY.

Fake It keeps the tones between 1500-2000 Hz. (not 1000) so that the 
harmonic energy is out of the passband.

Also the response of the sound card has some variation at different 
pitches (it's not a totally flat response), so try different tones.

Many more EU station on 15 m today than I have seen for a while.  17 m gave me a QSO with OD5KU for an ATNO earlier in the day.  Even earlier than that I worked JA on 160 m for the first time despite my hopelessly inadequate 5 ft agl antenna.

I thought my luck must have changed but I suppose sunspots could have been implicated.

Hello,

Does your K1 or K2 need repair? Tuneup?
Want to sell, but it needs some attention before offering it for sale?
In addition to tuning your rig, I can also rescue a building project you 
might have started some time ago.

See what my clients have said about my construction and service work at

Sorry, once again because I get a strange message..

 

Hi all,

 

Recently I came in the possession of a K3/0, the full size remote control.

 

There is plenty of space to install the pcb's of the RRC1258 remote control,
WiFi and a 12 V DC supply as well.

Cabling/connections will be made inside the K3/0, so no external connectors
to peripherals.

 

That way I will only have one "box" which is easy to take along.

 

Before " I invent the wheel again", has anyone done this as well?

 

If so, could you share pictures, diagrams, etc. with me.

That could save me quite some time (and possibly errors..) to find clear
spots on the main pc board to install all the pcb's.

 

Please share info off-line using henk.pa0c at gmail.com

Hi Ed,

Each of the K4's receivers has a fast-acting Carrier Operated Relay (COR) that activates between +20 and +25 dBm. When the COR triggers, it disconnects all active circuitry of the associated receiver from the antenna. COR hold time is programmable.

For signals that are below COR level but still extremely strong, the K4 can automatically (at the user's option) adjust receiver front-end gain to optimize dynamic range.

I wish people would actually read emails.....

I stated:

4.  The audio from WSJT-X been measured on a UPV audio analyser and there is less than 0.1dB variation when using a UMC404HD sound card.

I even numbered the relevant stuff to make it easy to read. A UPV audio analyser is quite good at it's job and something of an industry standard in EU broadcast measurements.

It seems that the stock 2.7kHz filter is the culprit. Confirmed privately by 2 EME operators and by Jim K9YC. So I will buy a couple of Inrad 2.8kHz filters.

You can pay me via PayPal friends, my call @ ARRL.net <http://arrl.net/> - will be shipped via USPS Media Mail no charge - it?ll arrive in a week - 10 days, depending on what mood the UPS is in these days. If you want it faster I can send it USPS Priority Mail for $3.50

Note that while Elecraft filters have been sourced from Inrad, Elecraft 
has an additional spec for IMD that may not be true of those purchased

Conrad and all:

Another reason I am glad that I chose the 2.8 KHz and 400 Hz filters 
when I purchased my K3 in 2010.

I do not use the 2nd IF when I run 2m-eme (JT65B under MAP65).  In 
fact I have FL3 open (no filter) and select it in diversity mode to 
reduce zero frequency "suck out" on the MAP65 spectrum screen.  I tap 
off the 1st IF from both main and subRx to feed dual SDR's before the filters.

But running either WSJT-10 or WSJT-X I do use line out audio with 2.8 
KHz filter selected in DATA  Mode.  I  run this on 6m and 23cm  eme.

------------------------------------
It seems that the stock 2.7kHz filter is the culprit. Confirmed 
privately by 2 EME operators and by Jim K9YC. So I will buy a couple 
of Inrad 2.8kHz filters.

I am running an SDR-IQ connected to the Rx In/Out BNC's on the rear
apron ...via a MiniCircuits Splitter.

With "RxAnt" engaged, it appears to me that there is very little signal
available to anywhere except the band to which the K3 is tuned.

Is this correct?

I'd previously figured that the Antenna input was before all the filters
and such.

Follow-up:

It looks like one of the KSYN3A synthesizers went toes up. The little green LED on synth #2 (sub rx) was on, but not the one on synth #1 (main rx). When I swapped them, the illuminated LED followed the (presumed) working synth. With just the one working synth installed for the main rx, the radio came to life, and the response to the OM command has the "V" back in it.

Subject: [Elecraft] P3 Display freeze - siloatr
Message-ID: <95c261e8-2af4-3535-0116-52fe126ddc92@gmx.net>

Hi everybody,

just to let you know:

while preparing my gear for WWDX I noticed that the P3 started to freeze 
the display for about 1 second, than continues to work for 2-3 seconds, 
then freezes, and so on. Very annoying to look at.

I disconnected all cables and traced it down to the 
RS232-to-PC-Connection. The logging programm polls the K3 (looped thru 
the P3) at 500mseconds, as all the time before.

I investigated further and realized I had an RS232-groundbreaker, a 10? 
part, switched in between.
Removed it, now works again like before!

Another cheap part that lasted for less than 3 years goes into the trash 
can.

I'm using macros inside N1MM logger function keys (wicked cool), to play M1
memory from the KDVR3, but no matter how I record my call on the KDVR3,
when played on an N1MM function call, I get something that sounds almost
like a squelch tail.  Any ideas on how to fix it?

Thanks!

Subject: [Elecraft] K3/0 direct connect to K3s within a Jeep (no Internet,
	no RemoteRIG). Is it feasible?
Message-ID: <96E4F58A-64BF-4727-8EBA-2F4110C354FD@me.com>

I have been operating from within my Jeep and primarily from the passenger seat. I spent a lot of effort perfecting a KX3/PX3 system where two of these are mounted on my dash. https://nomadic.blog/2019/10/22/suitcase-dxpedition-so2r-why-drive-a-boring-bmw-m-series-when-you-can-have-a-ferrari/  Works great but as an SSB guy I?d like a little more oomph and hence a KPA500 enters the picture.

My question is whether its possible/feasible to direct connect a K3s to a K3/0 mini. The use case is to leave the K3s/KPA500 in the back of the Jeep and have a K3/0 mounted on the dash. I really don?t want to use the RemoteRig boxes and wondered if its feasible to do this?

Hello Eric,

The entries look ok. Maybe in N1MM you have "cq repeat" checked to be "on"
AND the "Set CQ Repeat time" set to short. Try 10 secs or longer ... hope
this helps.

Message-ID: <CE8E6292-0D3E-4BE8-B608-E60052C05D51@tampabay.rr.com>

I have read and attempted to follow the instructions in the manual for training the ATU in the KPA-1500, however I am not sure that I am doing it correctly.   For instance, what mode should I use to produce a signal into the amplifier?  Should I provide the signal continuously while the amplifier is tuning? How do I know what the tuner has finished tuning for a particular band?  It appears that I have tuned my Cushcraft R7 for both 20 and 17 meters, but would like someone to give me detailed step by step instructions for the process. 
Thank you.

"How do I know what the tuner has finished tuning for a particular band?"

You can't train for a "band". You have to train (establish a tuning solution for) each "bin" within each band. For each bin you have to chose whether you want to chose the upper edge, lower edge, center, or some commonly used frequency within that bin 's range. Each bin tune needs to handled as a complete autotune sequence. Lots of manual steps that could be automated (except for reservations about the legality).

All comments based on experience with KAT500 not KPA1500.

I am trying to write macros for the PF 1 & 2 keys for the KPA 1500.

My objective is:
Have the PF1 button switch the Input to the K3s with the command ^PF1^XI0;
Have the PF2 button change the input type to serial (for Flex) with the
command ^PF2^XI3;

Neither one is working, where am I going wrong?

I assume that after I have these working with the command tested in the
1500 util, that saving them will send them to program the buttons on the
1500? Is this correct?

Use the KPA1500 Utility program. In the PF box for PF1 just put ^XI0;
In the PF2 box put ^XI3;

No need to put PF1 and PF2 in front.

To elaborate, the ^PF0 and ^PF1 are not valid commands. If you want to
string multiple commands on a button, each command must be followed by a
semicolon with no spaces.

Howard:

The KPA1500 PF1 and PF2 buttons are programmed from the KPA1500 Utility.
Choose the Configuration tab, and the PF Keys tab.

Enter the macros for PF1 and PF2, then "APPLY" or "OK".

The macros might be something this for PF1:      ^DTRADIO TYPE K3;^XI0; 

And this for PF2:    ^DTFLEX SERIAL;^XI3;

The ^DT text shows on the LCD screen when you hold the PF button to remind
you what it was intended to do.

Heads up!

Keeping with the suggested 10 year smoke detector replacement, and wanting to add a couple more and have them all alarm if one alarms, I bought Kidde wireless interconnected detectors. 
Well, start installation, read the manual. Under Locations To Avoid: Near amateur radios or other devices known to transmit an RF signal. 

So, guess I?ll send these back and get some hardwired interconnected units.

That is probably a recipe for noise, radiated by that interconnected 
wiring. The security industry has long been notorious for EMC to and 
from their systems. WiFi interfacing should reduce both significantly, 
but before committing to anything, chat up engineers at the company 
about RFI.

That might be the wrong thing to do. We had a number of wired
interconnected units in our house, but the one closest to the shack and
antennas started alarming every time I transmitted on 40m with more than
100 W, and because they were interconnected, the alarm was heard everywhere
in the house. I replaced that one detector with a battery-only,
non-interconnected unit and the problem went away - the non-interconnected
unit has no RFI problem, and neither does the interconnected part of the
system elsewhere in the house.

I would expect wireless interconnected units to be less of a problem than
wired ones. If one of them did have an RFI problem, it would be easy to
replace it with a no-interconnected unit at the vulnerable location to see
if that fixed the problem.

I have an older wired alarm system that uses serial data, and it is
indeed awful. The serial data is quite slow but it has no filtering. I
added an LC filter that works well enough to keep the RFI out of my
station, at least down to the level of what comes from my neighbors
and keeps my station from setting off the alarm system (most of the
time).

At my son's house, he and neighbors have some SimpliSafe and other
wireless alarm systems and the HF Ham bands are wiped out by the RFI.
I have no idea what nominal frequency range or signalling they use. I
would expect for battery life they would not transmit often, but
whatever they do to create the RFI is continuous.

I also have a hard wired smoke alarm from Kidde. That uses a DC
interconnect between units. I believe any unit that goes off pulls a
line up to about 9 V and they all go off. They are kind of cagey as to
exactly what the interconnect signal is though, so I may be a little
off.  I have not detected any issues with RFI or susceptibility. Those
may indeed work for you.

I do have a Spectrum Analyzer and multiple types of clamp on probes
and antennas but have not taken the time to do any quantitative
measurements of any of these.

Having to tell the Fire Department that the fire alarm is false is not
a good thing.

FWIW, we use a Nest Protect here (hardwired into A/C, too) and haven't had
problems with RFI. I imagine it'd be a different story if it didn't use
Wi-Fi, though.

Speaking of Wi-Fi, our Ubiquiti access point required at least four
Ethernet chokes, a third party PoE injector and CAT7 shielded cable to get
the RFI down to an acceptable level. That was a fairly surprising thing to
have happen but I guess PoE in general is well known to be really bad for
RFI (and the limited antenna possibilities at the QTH I'm sure didn't help
either).

The reason to keep smoke detectors from Amateur Radios is that they detect
smoke by ionization from a radioactive source.  A strong near field will set
them off.  The good news is that this is your indication that all is not
right at the feed line (Or the antenna is unhealthy close).  I have had this
experience myself, fixed the feed line and the issue went away.   That was
with 100w on 80 meters.  Unlike real smoke, the detector will stop
complaining when the transmission stops.

About 12 years ago we had a carbon monoxide detector in the upstairs hallway not far from the shack. Every time I was on a 2m net (could have been 6m, I forget...)the detector would start chirping, I even lowered power from 65 to 25 watts, same issue. Eventually the thing wouldn?t stop chirping at all so we threw it away, put a smoke detector in it?s place, got a 10 year carbon monoxide detector and put it in the guest bedroom which is further away from the shack and never had a problem again.

I had a battery-operated smoke detector that was set off by my 
transmissions. I totally wrapped it in aluminum foil and punched holes 
in the foil to match the openings in the plastic housing. No more trouble.

Of course this wouldn't work with a WiFi unit. But in my experience, 
WiFi appliances have always been less affected by my HF and 144MHz 
signals than wired ones whose wires act as antennas.

I have a Gen 1 Simplisafe system in our older MO outbuilding which is partially finished to house my shack.  It has been in operation for four years with no RFI issues.  

The adjacent outbuilding has a Gen 2 system that was installed last Spring ? I need to disable it and see if the grunge on 15 m goes away.   I do not think I operated from MO after installing it last spring.  It took 3+ hours of dealing with their care folks to get it to work.  When we were done I think I had them trained.

Carlos,

Do you have the internal frequency counter probe plugged into TP2?  That 
is one possible cause, remove it and retest.  CW or SSB mode?  All 
spurious signals should be greater than 43 dB below the carrier level - 
they cannot be expressed meaningfully in dBm, only with respect to the 
carrier.

The binocular toroid is a transformer to match the impedance of the PA 
collectors to 50 ohms, which is the input impedance of the Low Pass Filters.

BYP + IN means you have selected to have the ATU in-line but the antenna's
SWR was so low that the ATU algorithm decided just to bypass the L and C
components. Functionally, it's the same as BYP, but you know that the ATU
is enabled. This is exactly what you should expect with a dummy load.

I am attempting to submit the log once again. I am having trouble getting the log to submit to the forum. It has come back twice. Thanks to the relay stations for their help.

P 24 of the owner's manual near the bottom:

The ATU IN and the ATU BYP LEDs both illuminate to show the tuner is bypassed for this frequency.
When returning to the selected frequency, the internal ATU will recall the bypass mode, and both ATU IN and the ATU BYP LEDs will be illuminated.

I have a dummy load on Ant 2 on my KPA-1500.  When I have Ant 2 selected, on any bandI cannot select just "In."  When I hold the button to change ATU Mode, my only choices are BYP or BYP and IN both showing simultaneously.  What does the latter mean?

Message-ID: <AEDF6C47-AE51-4EE4-B34B-3448953370F8@w5jwp.org>

Hello Elecrafters,

I am interested in selling one of my two KX3/PX3/KXPA100 stations ? the location I planned to install this station at fell through and I would rather the package go to a good home, instead of collecting dust.

All hardware is less than 4 months old, factory assembled, in pristine condition, running up-to-date firmware and recent serial numbers.

KX3 160-6 All Mode Transceiver

  *   Includes KXFL3 KX3 Dual-Passband Roofing Filter
  *   Includes KXAT3 20 Watt Internal Automatic Antenna Tuner
  *   Includes KX3-2M-AT 2M Module with KXAT3
  *   Includes KXBC3 Battery Charger
  *   Includes MH3 Hand Mic
  *   Includes ES80 Carrying Case
  *   Includes Elecraft KX-LINE Book by Fred Cady
  *   Includes right-angle BNC to PL259 adapter cable
  *   Includes Heil-KX3 audio adapter
  *   Includes angled desk stand
  *   Includes original box and manual
  *   Includes power cable (unopened)
  *   Includes KXUSB cable (unopened)
  *   Includes SideKX front protective cover

PX3 Panadapter for KX3

  *   Includes original box and manual
  *   Includes power cable (unopened)
  *   Includes angled desk stand
  *   Includes KX3-PX3 accessory cable set
  *   Includes SideKX front protective cover

KXPA100 100W Amplifier

  *   Includes built-in-tuner
  *   Includes original box and manual
  *   Includes power cable
  *   Includes KXPA100-KX3 accessory cable set
  *   Includes SideKX front protective cover

I have no idea what the used value of this total package is ? I will entertain all reasonable offers.
New retail is $3,900 for all as of today?s pricing.
I have seen used prices ranging $2,750-$3,500.
I would rather sell here and avoid eBay fee?s.

Would rather sell the package as a whole, but willing to separate if the price is right.

Shipping is $35 via USPS to US destinations only.
Insurance through USPS is $50 and is STRONGLY recommended ? not responsible for any damage or theft.

This seemed odd to me at first, also, but it really made sense as I was
hopping all over the place during cqww this weekend, and could tell at a
glance at kpa1500 remote or front panel what it was up to.  Also, that I
had missed training a few bins...yikes.

Once you get used to it, it's the perfect solution.

Message-ID: <CAOdpi6GhmWp-vC5R6XAXAJj++jQMDMtKirj40D9DdXS061Fd6w@mail.gmail.com>

Hi All,
I have a  Elecraft Directional Coupler/Panadapter TX Sensor that I never
use.  It came along in a package deal I had on a K3S, so it's just sitting
around in the box with its E467139 cable.  The last time it was used was
when the original owner demoed it for me prior to my purchase, since then
it's been boxed.

Any idea of what it would bring, if offered, for sale?

Thanks in advance.

Radio waves are non-ionising radiation, so there is no fundamental 
reason why radio frequencies should trigger ionisation detectors.

Also, at least in Europe, ionisation detectors are no longer the 
preferred type. Optical detectors are the generally preferred type, and 
ones which combine heat and optical detection seem to be most favoured.

Actually ionisation detectors alarm when the current reduces, so 
additional ionisation would probably de-sensitise, rather than trigger 
them.  They include an alpha emitter to generate the ionisation, so are 
radioactive.

The main advantage is that they are cheap.

Howard,

Did you get your KPA1500 PF macros to work?  I use these all the time, 
doing exactly the same thing you want.

In the KPA1500 Utility, on the PF Keys tab, fill them in as:

PF1:    ^XI00;
PF2:	^XI30;

PF1 for K3 / K3S and PF2 for Flex.  I have Serial Speed XCVR set to 
38400 bps and have the USB Cables setup configured for the same speed.

Surely the binocular transformer is converting the input impedance of 
the filter to the optimum load line for the PA transistors.  Typically 
that would mean such that the the voltage swing was just short of the 
full supply rail for the worst case complex impedance, at the worst case 
acceptable SWR, for maximum power, and with that power.

Also that transformer provides negative feedback.

I'd expect the actual PA collector impedance to be a lot higher than the 
impedance reflected through the transformer, as transistors and FETs 
are, to a first approximation, current sources, although the negative 
feedback would actually make the reverse termination impedance much 
lower than that from the transformer.

A hint that is the case is the option for different winding ratio if you 
are always going to use a lower maximum power.  Maximising the voltage 
swing increases the efficiency.  The alternative ratio doesn't transform 
the filter input impedance down so much.

I mention this as there is a common misconception that the "maximum 
power transfer theorem" actually applies in such cases, when applying it 
would produce less than 50% efficiency.

Whilst I have read that California has been devastated by the horrific fires, and the world seems a little doomed with CV-19; There has also been signs of life within the Elecraft mother-ship, with K4 development. I am glad to see there is some progress for Elecraft, but as I am sitting 

So what is the current status of returning failed receiver back to Elecraft for repair - I have a dead KX3 - which was waiting the generation of a RSA since 21st May 2020?.  ??

I am sure that I am not the only person with equipment waiting return.

Hi Tim,

We?re still here and have been back accepting and repairing RSAs for many months. Elecraft is in good shape - Fortunately the fires were never close to the factory, which is not in a forested area.  

I apologize for any confusion with your repair request in May   Apparently there was a miscommunication on your request.  

I?m forwarding your email directy to our support team
and they should be in contact with you tomorrow (Tuesday).  

73,
Eric

Message-ID: <E18E0B45-CEEC-479F-9EE7-2203D5EAEC9B@arrl.net>

Need a bit of help here-I?ve installed the 160 receive module  on my venerable K2 #1010 which I built back in 2000..for some reason I seemed to have created a short across  the main antenna jack (J4) with this installation. In testing after Installation the reciever was totally deaf as was TX, and I found that there?s a short somewhere between the center pin and the outer sleeve of J4,the main BNC jack first the radio. I inspected the jack just in case,but appears okay. I?m suspecting some sort of short around J14,the 16 pin jack for the adapter. When installed,the radio functions normally and the module is recognized in the menu. Just  zip on recieve and transmit. Inspection of the 16 pin socket didn?t reveal  anything obvious under a magnifier. The radio was in daily use up to a few days before. I checked the obvious things ,or so I thought!
 Thanks for any help

Dan,

The K2 BNC jack will have a DC path to ground whether the K160RX is 
installed or not.  It is not "ground" for RF, but will show a low DC 
path to ground if you measure it with your DMM.  If you disconnect lead 
3 or 4 of T4, the DC short to ground will go away.

Don W3FPR

I am selling my personal KPA500 ? it is in excellent condition, both
operationally and cosmetically.   I purchased it from the original owner in
December of 2016.  It has performed flawlessly.  I am a very light user of
all my equipment, especially the KPA500.  I estimate there is less than 10
hours ?operating? time on the amp!  Therefore, the reason I am selling ? it
needs to go to a good shack where is can be fully utilized.


It will arrive in an Elecraft KPA500 box with inserts, DC power cord (I ran
it on 240V), custom cover and color copied, spiral bound Owner?s Manual.



My price is  $1800 +shipping & insurance to your CONUSA QTH address.  I DO
NOT ship internationally.



I will accept USPO money order, bank check or PayPal ? ?friends and family?
payment or Buyer pays +3% for PayPal fees.  Unfortunately, due to parts
swappers, there is no warranty expressed or implied.



Questions, please email me* direct* at my call at arrl.net.  Pictures are
forthcoming.



Thank you,

John Altman

Just curious -- why are you unwilling to ship to AK or HI? The buyer is 
paying.

Message-ID: <015402fc-aa2b-5c2b-036a-aba47d498e35@rthorne.net>

Came out to the shack this morning and the KPA-1500 is not going into 
transmit.

I verified that the PTT cable is shorting when the Flex 6600 goes into 
transmit.

The amp operates properly otherwise. The ATU works, it shows the power 
out from the 6600, it just won't go into transmit (no Red TX LED).

I did upgrade to firmware 2.48 yesterday and the amp worked fine.  I 
downgraded to 2.38 this morning, same result, the amp will not go into 
transmit.

What am I missing early this morning with only a half cup of coffee.

Thanks

Try shorting the RCA connector on the amp and see if the TX light comes on. 

Load the KPA1500 utility and look at the log file. 

Look on the KPA1500 and see what frequency it thinks the amp is on. If it is out of band it will not TX. 

That is where I would start. Also check that all cables are seated properly.

Anyone willing to share their delivery Info with us?   I?m surprised no one has announced (bragged) about receipt of a new K4 radio. Shipments started in early September we thought.

David and all,

I am a little late chiming in here, but all David's points are correct 
except for a caution on one.

The alternate winding ratio for T4 should never be used with the KSB2 or 
the KPA100 installed.  It is OK for power in CW kept below 5 watts.
If the PA is operated above 5 watts, it becomes more and more 
inefficient as the power is increased.

I have repaired several for buyers of a used K2 who had problems 
developing full output and observed that the current draw at 10 watts 
was quite high, sometimes causing HiCur messages.

73,
Don W3FPR

Subject: [Elecraft] K2 upgrade kit sequence
Message-ID: <3b751d95-270f-41f6-8463-8fa31949b345@me.com>

For anyone considering updating an old K2, a small point that may not be clear in the instructions is that the K2ATOBKT is sort of a "top level" kit that "controls" the other mod kits. So instead of installing the various kits in their calendar order of publishing (2001, 2002, 2003, etc.), the way to do it is to get all the kits, then follow the instructions for the K2ATOBKT. Those instructions call out the other kits (e.g., "Now follow the instructions supplied with BFOMDKT") in the appropriate sequence.?


If you try to do them in calendar order (like I did), you will encounter confusion regarding "missing" parts and a couple of cases of "didn't I already change that???"



Somebody with access to the Elecraft web site might want to clarify this a bit on the kit ordering page.? :-)

What is the intended purpose?  There are many SDR receiver options, 
starting around $30, and with nice products in the $100 - $300 range. 
All run on the USB port of a computer (mostly Windoze), and cover 
relatively wide spectrum. There are multiple choices of user software, 
nearly all of it freeware. And as long as you keep them out of overload, 
they blow away many excellent vintage products.

Doug,

You are exactly right.  If you follow the K2 history, you will find that 
the K2 A TO B kit was issued to pull all the prior mods together as well 
as providing instructions about the best sequence to use when doing a 
full upgrade.  That happened at the same time the B level boards were 
laid out which incorporated all the prior mods (SN3000 and above).

So anyone contemplating a full K2 upgrade, start with the K2ATOBKT and 
install the other kits when the A to B instructions call for them.

One other benefit is that the K2ATOBKT instructions tell you when to do 
the alignment instead of doing the alignment after each of the mod kits.

The A to B mod will not quite get you to a post 3000 SN equivalent 
unless you also change the IF crystals (not necessary if the SN being 
upgraded is above 2560 which was when the crystals were changed).
That leaves only the K2 Keying Waveshape mod which appeared near SN 
4600, but the kit has been discontinued for lack of a leaded PIN diode. 
New K2 kits use an SMD diode on a carrier board, but so far, that SMD 
diode has not made it into the mod kit instructions - yes, I know the 
new KPA100 kit calls for it as a prerequisite.

It will also not deal with changes to the KSB2 (the PSK mod) and the 
KSB2 crystals and bandwidth change to 2.4kHz.  Check the resistors on 
your KSB2 board against the mod instructions to determine if you already 
have it installed, it was put into production early on.

Don't forget to upgrade the KPA100 too, the KPA100UPKT will 'do it all', 
there is no need for the KPA100MDKT since the parts are included in the 
KPA100UPKT.

So, there is the FULL story - I have upgraded many, many K2s.  Anytime I 
had an older K2 in for repair, I gave the owner the option of upgrading 
or just repairing - almost all chose to upgrade.  And my upgraded Field 
Test K2 SN 0020 performs as well as a new one.

73,
Don W3FPR

Well you saved up some fun for later. I have with exception of the 1500w amp 
and k4, I have everthing else.
Whoops, I do need a 2 Meter Xverter, have the 6 meter one.

Still great fun with K2.  The receive works side by side equal with my K3S. 
And having built all the options, it?s a high performance rig and Its fun
to make the same contacts as all the others out there.

Hope to see you on the air soon.

Well, regular reflector email works well, and is my preference  If it is 
changed, I will go down "kicking and screaming".  Threads lose something 
for me - subjects change, but participants do not change the subject 
line, so things get mixed up.

If you want threading a good email client like Thunderbird will give you 
that option if you choose.  You can also, read the email on Nabble which 
can display in threaded format.

KUSI is literally fake news--there is no such entity registered with the
California Secretary of State's office, either as a corporate name, or other
business entity--in case any of you took this seriously.

Subject: [Elecraft] Smoke Detectors
Message-ID: <05a001d6ad9e$38cff880$aa6fe980$@comcast.net>

Radio waves are non-Ionizing. I hope we all know that and know one another
know that.  However the near field is an electrical field.  The smoke
detector compares the ionization between two chambers, both with the same
radioactive source. One is exposed to the environment (smoke) and the other
is not while both have the same radioactive source.  An imbalance in the two
chambers indicates smoke impeding ionizing radiation.  It is triggered by a
very small amount of smoke, barely visible to the eye.   The means of
detection is electronic and can be affected by a strong near field.   Most
of the smoke detectors I know of here in the US are the ion type.  

It may also be that other electronics in the detector are affected by the
near field.   That would be another theory but I think that affecting the
detector itself is more likely.

Is anything that one disagrees with fake news???

Its new in box, includes manual etc and all the parts.

Don,

While the keying mod kit instructions haven't been updated, the K2 
manual has been updated for the SMD diode on a carrier board 
installation. Pg 60 of the Rev I k2 manual.

I was able to order all of the parts for the keying modification from 
Elecraft.

Here is the list of parts:

Well, RF (AKA "Radio Waves") can falsely trigger all sorts of equipment
that was not "designed" to work with, or be influenced by them.

That is the classic EMC Susceptibility or Immunity problem.? Basically,
poor design and/or implementation of the affected (or sometimes bad
installation of an otherwise good) device.

To do it right, costs money, so you can guess the rest.


Not just smoke detectors either.

Dave, I totally agree. I am sure the ?problem? the manufacturer is cautioning about is RF, since my original post was about ?wireless connected? detectors. My gripe was nothing in the sales literature warned against it. Not till I bought the units and read the installation guide

I guess we need a "no troll" policy as well.
A mis-leading subject line.
No Elecraft content in the body of the email.
A link that leads to a politicized article.
That is the definition of a troll email.
Nothing about the K4 to be found...
The wrong person apologized in this thread.

Most RFI to/from ham radio and "devices" is caused by poorly designed 
electronics using interconnected wiring as TX/RX antennas. Because of 
the frequencies on which they operate, WiFi-connected devices with no 
exterior wiring are inherently FAR less likely to create or receive RFI 
IF they operate on internal batteries. If running from the AC line or a 
switching power supply (wall wart, wall lump, etc.) the PSU will almost 
certainly create RFI noise and wiring both on the AC and DC side will 
radiate it.

Bottom line -- choose stand-alone devices with internal batteries and no 
external wiring for minimum RFI.

In your situation, I would try one of them before returning them.

I have ended up with 2 bad KI03B boards E850645.? Both bad in the USB 
circuit.? I did some basic checks resistance wise they recommended but 
found no problems.? Elecraft said chances of repair was slim and would 
not be economical to try.? I think all the other functions are okay ie 
think they are still working okay if you come in via the serial port.? 
Seems a shame to toss them into the dumpster? but unless someone has had 
some experience of repairing them that may be the route.? Anyone ever 
attempted at repair of the USB circuit on these?? 73 Mike K4PI

Strongly suggest contacting county fire marshal before selecting wireless
only detectors.

You don?t want to violate code and have any insurance claim denied if these
is an event.

We switched to wireless alarm connected, internal battery detectors due to the occasional RFI interference caused by running a little power on 80 meters. Our alarm company actually had some experience with RFI issues and made the recommendation. I installed them and have a calendar reminder to swap the batteries every fall when the time changes. 

Local fire code does not require detectors. Insurance folks give us a break on rates for having them - wired or otherwise here in Ga.

Message-ID: <CALhxr4b3ETf9AUwyt=MML78GZ7CXWz2GJu-kAx40tTOnht6zqg@mail.gmail.com>

Today I find that I get a HI CUR error when transmitting at just a little
over 50 watts. Switched to a DL and find that on 40 meters my K3 draws more
current at 50 watts than it does on all the other bands. This is with the
tuner bypassed and hooked to one of my old cantennas. SWR shows flat on 40
and all other bands So I am guessing band pass filter issues. Has anyone
else had a similar experience with one band being way out of whack?

Elecraft and I was going to send my K3 back to them and then I saw a few
YouTube videos and I installed a TON of toroids on the K3 and Amp and every
wire in my shack and no more HI CUR message. Best of luck!

Hi,

I noticed last night i have a raspy hum on CW and SSB when transmitting on
20m.  The other bands seem to be fine.  Has anyone else encountered this?  

I have searched the archive and another person experienced the same but I
can't see if the operator found a solution.

Cheers,

Dave.

Stan;

Please elaborate - what voltage is the HV dropping to?

We set up the factory-build units for the voltages at the factory. What you encounter might be different, so you will need to go through the adjustment exercise described in the manual on page 6 of the rev C3 manual (it might have moved in other revisions of the manual). Also, make sure all the chassis screws are tight, especially the ones holding the rectifier board, and you may need to properly retighten the screw holding down the big transformer to get it to quiet down. 

Once you get all this taken care of, the KPA500 is a pleasure to use. But then I?m biased?

The support guys have been really busy lately, but they will get back to you. You might want to try a phone call to make sure.

73!

Ferrites are probably not the answer here. Problem showed up with no
changes in configuration, and problem happens with a dummy load. Plus I
have ferrites in most of those locations already. This only happens on 40
meters and happens both with antenna connected and when dummy load
connected.

Total BS. They're trying to sell you stuff. NONE of this is necessary. 
What IS critical is antenna design, how they are fed, simple bonding, 
and the use of chokes at the feedpoint of each antenna.

For bonding, study http://k9yc.com/GroundingAndAudio.pdf

For chokes, study http://k9yc.com/2018Cookbook.pdf

For antennas, study the ARRL Handbook and Antenna Book.

Note that I'm not selling anything. :)

It's important to understand that these safety codes are LOCAL -- 
usually by state, but also by county and/or city. There are "guideline" 
codes, like the National Electric Code, that are adopted by most local 
authorities, and those guideline codes are updated every few years. 
Often the local code (which is the Law) is years behind.

California law DOES require smoke detectors. I don't know enough about 
the law to know the limitations on type. The ones we have are 
stand-alone, running on a standard replaceable battery.

Exactly. Here in Folsom, Sacramento County, we are required to have wired smoke detectors AND battery powered carbon monoxide detectors. In fact, we had our roof replaced a few years ago and the building inspectors would not pass it unless those carbon monoxide detectors were installed. For backup we also installed battery powered smoke detectors in each room.

For what it?s worth, the American Red Cross is recommending installation of units that have 10-year lithium ion batteries which are sealed and not replaceable.  History has shown that kids tend to remove the batteries for their toys and games.  

They also say the test button tests only the battery, not the combustion-products detection circuitry.  The circuitry in the older units (with replaceable batteries) proved to be effective only for five years.

Any detector older than five years should be thrown away and replaced with the new 10-year design.

The smoke detectors we have here are wired into the security system - no 
replaceable batteries - except for one which is standalone in the 
bedroom and was required to be added by the inspector when we built the 
house even with the whole house system in place. No RFI problems observed.

We do know the whole house detectors work - the security folks have 
called those times when we let the toast burn in the oven!  I had to 
have one in the shop building moved because it was right over the 
workbench and would alarm any time I was doing fine power sanding - even 
though I had a dust collector running.

Thanks for the info on the 10 year units.  We have replaced the 
standalone one 3 times in 17 years, so we are about right on a 5 year 
replacement schedule.

The sealed batteries in the ones that we have are replaceable but the
cells within them are not.  Experience with the "10-year" batteries is
that they  start getting flaky at about 7-8 years, but the building
management is very cooperative about replacing them when they start
chirping.

Message-ID: <1604106704732-0.post@n2.nabble.com>

Hi folks,

I recently posted about my raspy CW audio on the K2.  It is most evident on
20 and 40m.  My shack is grounded.

Today I replaced the RFC15 just to make sure that wasn't the issue.

I have removed the KPA 100 and returned the QRP lid.  The issue still
exists.

Any suggestions to clean the CW transmission up would be appreciated.  The
radio is not suitable for operation at present with the modulation on the CW
transmission.

Cheers,

Dave

Hi,

The issues with Hum seem to have been sorted.  I did some tests with a few
stations, and a ZL and they indicated my CW transmissions are as clean as a
whistle.

I think that problem may have been some RF in the shack.  Never mind... it
gave me the morning to run around and get the panels off the radio and
double check a few things.

Sorry for the intrusion.  73 and hope to see you all on air.

Hum, I was getting this HI CUR error only with my Directive Systems 6 Meter

not? The toroids fixed my issue. I just love how some of the forum or so

I second the motion to replace ALL the older smoke detectors, not only in YOUR home BUT IN YOUR CHILDREN?S HOMES!  My daughters husband is not that bright and I replaced all their smoke detectors and monitor them when we visit.  They live in a 112 year old run down mansion (fire trap) with kids spread all over.  The new Kidde ones are sealed and no one can mess with them (Thank God!) and good for 10 years.

For what it?s worth, the American Red Cross is recommending installation of units that have 10-year lithium ion batteries which are sealed and not replaceable.  History has shown that kids tend to remove the batteries for their toys and games.  

They also say the test button tests only the battery, not the combustion-products detection circuitry.  The circuitry in the older units (with replaceable batteries) proved to be effective only for five years.

Any detector older than five years should be thrown away and replaced with the new 10-year design.

Two comments ?

The idea behind the 10 year life batteries in sealed detectors is that the battery and the sensor element both need to be retired at the 10 year point.  It is not a good idea to put new batteries in any detector at around the 10 year point as the sensor needs replacement, too.

We had 20 year old Firex smoke detectors.  Kidde acquired Firex and now makes replacements with 10 year lifetimes.  They are not plug and play for 2 reasons.  The Firex pigtail wired into the house does not mate with the Kidde detectors, and the plastic flange that mates to the electrical box is not compatible, either.  Kidde sells a plug adapter that IMO is too bulky behind their detector to readily fit into the electrical box.  So, plan to install a new mounting flange, remove the prior pigtail and install a new one.

Of course you may find obstacles I did not and this only applies to the brands discussed.

Hello Alan

That was my antenna design. It has a teflon coax 1/2 wave balun that 
kills RF on the shield side of the coax, but there is not much you can 
do about near field energy getting picked up by the outside of the coax 
due to radiation.? It is best to tape the coax down snugly along the 
boom and masting etc.? Still, it does not hurt to add more RF chokes to 
any antenna! It is pretty easy for RF energy to get impressed on the 
outside of the coax in any typical installation.? The balun at the 
antenna only keeps the energy from the coax center conductor from going 
to the outside of the coax at the feedpoint.

The way I check for decoupling effectiveness is to match the antenna 
really well, and then run your hand along the outside of the feedline 
near the feed. While looking at the screen of a network analyzer, you 
can see little perturbations in the return loss 20 or 30 dB down if 
there is RF leaking to the outside of the feedline. This is a 
qualitative test and you can estimate the bandwidth of the decoupling 
network. You will see larger return loss change amounts away from the 
resonant frequency of the decoupling element.? This won't apply to 
ferrites, as they can be broadband, but with a quarter wave choke, or 
similar, you can definitely see the effect.

Mike -

You can view the Schematic diagrams (6 pages) for the Elecraft KIO3B module.
https://ftp.elecraft.com/K3S/Manuals%20Downloads/E740323%20K3s%20Schematic%20Files.pdf
The KIO3B is a multi-function module, that includes these functions:
1. RF Board interface
2. Digital I/O interface
3. Audio I/O interface
4. USB, Codec, RS232
FTDI FT232R (USB), TI PCM2901 (CODEC), TUSB2036 (2/3 port USB hub)
5. Digital I/O
6. Audio I/O
==
It is NOT impossible to repair or troubleshoot (component-level), 
BUT it can be time consuming for the novice or weekend technician.
This is why Elecraft stated ?economical? (their bench time is NOT Free).
?
Sage advice from my high school electronics instructor, WB9FUR (sk, 2016) has served me well : External event (ESD, Over-voltage, Op error) and I/O ports are major causes of module or circuit failures.  Electronic devices rarely ?die? for no reason (assumes QA production of part).
?
?What functionality? has failed will narrow the circuit areas and components to examine.  IF you can ?think thru? those observed symptoms, many failures can be pinpointed with a DVM to a few key components. 
SMT repair experience and tools reduces repair time.
?
This summer, I repaired an ESE ES-188 Master Clock ... that the reseller suspected was not working properly.  Visual and operations inspection:
* Not damage to tinned copper foil traces on PC board.
* Bulging 25V electrolytic caps (85? import brand) on DC filtering - replaced (105?)
* Multi-serial TTL level ports from microprocessor were inconsistent 
- replaced MAX233 (resolved one port)
- replaced 74LS04 and 74LS08 (resolved other ports)

I did not even pull out my DVM ... the secondary DC ripple was eliminated, and an external event (ESD?) likely entered thru serial port ... damaged the 3 ICs replaced.
Those 3 parts were closest to DC power bus and serial port entrance to PC board.

It?s been running on the bench, driving NTP and IRIG-B remote clock for past 3 months ... no issues.  IF I were to resell, I would check with DVM & possibly scope.

I have ended up with 2 bad KI03B boards E850645.
Both bad in the USB circuit.
I did some basic checks resistance wise they recommended, but found no problems.
Elecraft said chances of repair was slim and would not be economical to try.
I think all the other functions are okay (think they are still working okay if you come in via the serial port).
Seems a shame to toss them into the dumpster, but unless someone has had 
some experience of repairing them that may be the route.
Anyone ever attempted at repair of the USB circuit on these??

 Dave
So where is the optimum place to place the ferrites for this antenna if you have a problem like Alan described? 

Does the near field extend roughly to half the stacking distance of that antenna (i.e. 6 feet or so), making that the best place for the ferrites? 

Does a mostly vertical coax passing through the near field of a horizontally polarized antenna (i.e. an antenna side mounted to a tower) need ferrites?

Do you need to decouple ALL of the rest of your coaxes and control lines at the lower near field edge of that antenna (or at some other point)? I have heard that argument (decouple everything) made to improve performance of inverted L antennas on 160 meters located near a tower.

You can cure that condition by installing the VCOSHLDMD from Elecraft. 
It adds a mu-metal shield around T5 so the transformer core is not 
modulated by the magnetic field from the power supply transformer.

If you do install that mod, first adjust the T5 turns spacing and then 
put the shield around T5 and make a final adjustment by moving the end 
turns of the red winding a bit closer together or further apart.

That last step is not mentioned in the instructions, but I have found it 
necessary.

No.  This is not the solution for what Pete describes and for what I and
others also experience.  Switching antennas, even antenna ports, often gives
very different power output numbers for the same drive levels from the
K3/K3S, even when appropriate and acceptable tuning solutions are found.

Using an external antenna switch on a single KPA1500 antenna port can be
problematic with the KPA1500 in cases where different tuning solutions are
necessary for different antennas.  Currently, there is no means to tell the
KPA1500 to use a different solution other than "trial and error" which means
providing RF on the "new" antenna, allowing the KPA1500 to find the proper
(trained) solution, change to that solution, and proceed.  At full power,
this process can result in an alarm which disables the amplifier,
inconvenient in the heat of battle (contest).

I have also noted that after not using the KPA1500 for a "long time" which
could be 15-30 minutes, power output can exceed alarm settings (well over
1500 Watts).  And when used some more, the power output decreases to 1500
without any exciter adjustments.  This means the KPA1500 gain figure seems
to increase after "resting" and decreases with use.

"Perfect" antennas that are always 50 Ohms and non-reactive won't cause
these symptoms.  I hope someday to have those.

This happens due to heating of the finals (network); typically 1500 
watts when cold (15-25C in my shack), drops to 1400 watts once warmed up 
(50-60C).? One can either adjust as needed or just accept 1500 cold and 
the drop (much less than one dB); but of course one should pay attention 
in all cases, should the limit exceed the permitted levels.

True gain values should include the temp of the amp; it matters.

90% of the time, when I use the amp, I'll run <1200 watts out, even 
though there is already plenty of headroom in the amp.? It's rare that 
the few hundred more watts makes any real difference (but it's nice to 
have!).

Now that winter is starting (North Idaho), it also takes the chill off 
the shack!

NOT judgemental, but an attempt by those of us who understand how stuff 
actually works to share that with others (the several thousand hams who 
read this and other email reflectors) so that false ideas and solutions 
are less likely to be accepted and propagated.

Anyone who doesn't want to learn is welcome to use their delete key on

Have been reading all the threads on this issue is you (and others) are right on with the issue.  I operate contests here (both cw and ssb) and have many multiple antennas for the same band.  

What I  have dome is train the AL1500 ATU for the main antenna I will probably use on that band, and unfortunately (the cost) I purchased a Palstar ATU for a new JK 403 I put up and trained it for that antenna and when I switch to the JK403.  I turn off the AL1500 ATU and switch over to the Palstar and visa versa.
This is done for the other bands/antennas also.  I know it?s a pain (and an expense) but it works for me.

Dave,

First try the VCOSHLDKT from Elecraft.  See my reflector post at 12:37 
today.

Alternately, move anything containing a transformer 2 feet or more away 
from the K2.

Hi Mike,

I would put the ferrite at the end of the coax before it goes into the 
rig if there were rf coming down the coax. Common mode energy can and 
will get on the outside of the coax. I am not an expert on this, but I 
would expect that any problem that would cause a transmitter to 
misbehave would? involve strong levels most likely encountered near the 
antenna where the fields could be high.?? Of all the folks that have 
used that 5 element six meter yagi, (me included) No one has ever had a 
stray RF problem. Running the coax perpendicular to the elements and 
tied down to the boom is all that is needed to keep things quiet.? I am 
at a loss to explain any other outcome.

I suppose there could be a fault in the balun area, but I would think 
that the SWR would climb well above 1:1 in that case.

If there is ever any question about where to place ferrites, I?ll say in general, put the ferrites at both ends of the coax (unless its a really short run). 

Some may argue that that is overkill. While there are always exceptional circumstances, I would in general respectfully disagree with them if they did. While the benefits of placing them at the feed point are well documented, I have found that replicating the ferrites at the other end of the coax generally reduces noise in the receiver, making it possible to hear and thus work more stations? ;-) 

It would also be part of the solution to rf in the shack, provided that the ferrites provide enough choking impedance. 5000 ohms at the frequencies in question would likely do, but referring to K9YC?s papers for the specifics is advised.

Ferrites at both ends, along with proper bounding and grounding of the whole station a la K9YC has always worked well for me.
