[Elecraft] More on 1E for FD, QRP K3?

[Doug Faunt N6TQS +1-510-717-1197]

Does the K3 cut off the 100W PA when the power is set to QRP levels?  Or am
I conflating that with the K2?
I'm looking to run 1E for FD without spending too much on a battery.
Although a big battery and/or using the KX3 are beginning to look more
attractive.

I wish I had the marginal size 31 battery I took out of HARVEY GAMAGE last
summer, but that was 9 months ago and in Maine.

Re: [Elecraft] Quiet Ductless HVAC System

[Bob McGraw K4TAX]

And one must remember that most folks will spend the least amount of 
money necessary to get the HVAC system working or perhaps install a new 
system.  And most of these folks have no clue about RFI, but are only 
concerned if their abode is hot or cold, warm or comfortable.


As a purchasing manager I know once said "that's the best part we can 
buy for under a nickel".

Bob, K4TAX


You must remember that the parts that go in much of this equipment is 
supplied by the lowest bidder.


Realistically when you see the number of active hams who buy AC products 
vs the number sold you will realize it a very uphill battle. Very noisy 
led bulbs have been sold for how long? They are a known source too.


 When price is the major factor quality always suffer. You can't have

Re: [Elecraft] RE; How well does the K3 work with lower power supply voltage . . .

[Bill Frantz]

When our club, the West Valley Amateur Radio Association, does 
field day, we use many K3 and Flex transceivers. We run them 
from 12 volt lead-acid batteries with solar power systems to top 
up the batteries. We have had not had any significant problems 
in any of SSB, CW, or Digital, although I think the the digital 
stations have the heaviest battery drain. We have noticed that 
before dawn, when the batteries are getting low, the IMD 
increases and we get more QRM from other stations in our 
operation. Swapping in a fresh battery always cures the problem.


Note that we run QRP, which helps with avoiding intra-station 
QRM and boosts the score.


If I were buying batteries for portable/field operation today, I 
would look at the Bioenno LiFePO4 batteries. Good power/weight 
and power/size ratios and near full voltage until the end of 
their capacity. The down side is they are more expensive the 
lead-acid batteries.

Re: [Elecraft] K3S support/warranty statement

[Don Wilhelm]

Support for the K3/K3S will continue for a long time to come.
Consider that support for the legacy products - K2/K1/KX1 and XV 
transverters is still available and active - even if those products 
other than the K2 have been discontinued.


Support is different from availability of the product.

Although I am no longer "official", I do know that support for all the 
legacy products as well as the K3/K3S is continuing.

[Elecraft] RE; How well does the K3 work with lower power supply voltage . . .

[John Kountz]

Doug,
Like the Monte Python joke, 
Observer: My dog has no nose
Question: How does it smell?
Observer: Horrible!
I have two K3 transceivers and have attempted to use them on several Field Days 
with limited joy and unlimited disappointment.  I've attempted to use one or 
the other with 120 Watt solar cells and 100 
AH GelCel and/or Lead Acid batteries which had been charged beforehand.  As 
long as there is healthy sunlight and you have a duty cycle of between 10 and 
15 percent transmission with 85 to 90
 percent monitoring you'll have a functioning station.  But, when the sun goes 
down or you get into a run you'll find yourself out of order.as the battery 
drops below a nominal 13 VDC..  Operation after  twilight, forget it.  Again, 
it's the 13 VDC cutoff.   I've used 40 amp boost converters supporting a 13.6 
VDC out for a range of input voltages with success, but you can end up frying a 
battery as the converter struggle to suck 13.6 VDC out of a battery dipping 
below 10.5 VDC on transmissions.  Although I've not tried it, I suspect a 
Yamaha or Honda 1 KW generator would keep the K3 running, but you're in another 
category.
Have fun and 73,

Re: [Elecraft] Elecraft IS shipping all of our amp models

[W6IPA]

Eric,

Maybe the best would be to update the Shipping Status ,and other statement of 
support for the rest of the line.
I posted earlier a question about the support status of K3/K3s and 
availablability of parts.
I have not found any definitive statement about that.

I for one love the Elecraft products, but I am finding myself looking at 
alternatives for an upcoming upgrade.

I don't like it either. I'm in the middle of fighting with a trio of 
noisy inverters where I live. The RF noise is so bad it kills 2 meters 
and UHF. Background noise is S9 all the time. Even at night. Unless its 
dark and I kill the feed to the panels. The installer is no help and I 
don't own the building. FCC said call the manufacturer. Great. My KX3 
allows a respite by going out into the field. Steve kb1chu

in the northwest (Seattle area).  I probably should add that when we 
go to our condo on Kauai the first thing my wife does is to turn off 
the AC unit.

Re: [Elecraft] How to allow K3S to feed multiple logging programs on my laptop?

[Ed Pflueger]

I use Win4K3suite and com0com and run 6 programs simultaneously into my K3S.
No problem, I'm running Dxbase, LOG4OM, DX4WIN, and AClog at the same time
just trying out to see which one I want to stick with.  I've been using
Dxbase since 1988 and it's my favorite but no updates since a long time.

You are correct, as usual.   My intent in citing motors, et al. 
was that MOST of these devices, especially these days, are

[Elecraft] Elecraft IS shipping all of our amp models

[Eric Swartz]

Just to break up the prior thread's incorrect subject line, here is my post
from a moment ago with a correct subject line :-)


Folks,

As noted in my earlier email on this thread, we are currently shipping
-all- of our amplifiers, including the KXPA100, KPA500 and KPA1500.

We are shipping a batch of KXPA100 orders tomorrow and will be shipping the
original poster to this thread his KXPA100 next week. :-)

Re: [Elecraft] How to allow K3S to feed multiple logging programs on my laptop?

[Grant VK5GR]

I can vouch for Win4K3Suite - I currently have DXKeeper(DXCommander), N1MM,
WSJT, FLDigi, MRP40 and others all connected. The only problem I still have
is WSJT and FLDigi fight a little for which mode the radio should be in to
do a certain task. I just stop the one not being used and all is fine. 

He gives you 30 days free of full functionality to see if you can make it go
with what you want. I haven't looked back with my station and haven't had to
reconfigure my digital programs and loggers once since implementing it when
switching modes. It is in my mind a software incarnation of a CI-V router
for Icom radios. It has unlocked a lot of operating ease with my K3 and K3S.

Grant VK5GR

The Elecraft shipping status indicates the KAT100 is “backordered”.  That

Have you contacted them to see whether or not you can actually get one, and if 
if not now, when?

Re: [Elecraft] Alternative AMP to KX3 since Elecraft has temporarily stopped making AMPS

[Don Wilhelm]

Fear not, the KXPA100 will again be offered as will the KX3 and KX2.
If you get a response that it is not available, that means that the 
in-stock supply has been exhausted.


But we will have to wait until after the lockdown in California is 
lifted.  It affects not only Elecraft, but also the suppliers of the 
boards, enclosures, etc.  Many of the ICs are offshore items and time 
will tell when they will be available and shipped.
Patience during this critical period is required, although many are 
getting restless.


Meanwhile, the K4 is being refined as the engineering staff is able to 
work from home.


Sales and support and K3 repairs are also able to work from home, as 
well as some of the production folks.  It is assembly that is in a bind 
- even if they can get the parts, assembly is a hands-on process that is 
difficult to do in a work-from-home environment.


See the Elecraft Newsletter to be informed of what steps are being taken 
in the office in preparation for reopening.

Re: [Elecraft] K3 on battery?

[Wes]

"Working" rather than working well with a clean signal are two different things.

A K3(S), as well as almost any other "12V" rig, is prone to increased TX IMD as 
the supply voltage is reduced.  For FD, with reduced efficiency antennas and no 
amplifiers, it's probably okay, but for everyday use, it would be bad form.

How well does the K3 work with lower power supply voltage, such as

Relearning the K3 would probably be easier than learning the KX3.

MOSTLY the air handling unit usually, and specifically the variable 
frequency drives, electronic control modules, et al whatever they

Re: [Elecraft] Alternative AMP to KX3 since Elecraft has temporarily stopped making AMPS

[Matt Maguire]

The KXPA100 and associated ATU is well integrated with KX3, and it
also works very nicely with the K2 if you make up the keying circuit
mod. It's sad to hear they've stopped production for the time being...

Re: [Elecraft] k3 no control

[Ian Kahn]

Joe,

The Prolific chip set has a long history of issues. It goes back to when
the Chinese started making knock-offs of them, and pirating the drivers.
You probably got a bad driver set in your download. As Don said, get rid of
that cable. Get one with an FTDI chip set in it. The Elecraft KUSB cable is
very high quality and very reliable. You won't regret the investment.

73 de,

Re: [Elecraft] K2 NEED to buy KAT100-1

[Grant Youngman]

The Elecraft shipping status indicates the KAT100 is “backordered”.  That 
doesn’t mean it isn’t or won’t be available.  There may be a delay, of course.  
Have you contacted them to see whether or not you can actually get one, and if 
if not now, when?

If so, you need to follow the steps to "Force a Firmware Download"

Get rid of that Prolific USB to Serial adapter and get one with the FTDI 
chipset - preferably the current KUSB.

[Elecraft] K2 NEED to buy KAT100-1

[NJMike]

I've just been informed by Elecraft that the KAT100-1 antenna tuner is no
longer available.  

I ordered both the tuner and the KPA-100 amplifier but, of course, the
amplifier does me no good without the tuner.

I realize that I can probably find another tuner but hey, the KAT100 is the
PERFECT matching box!

If anyone has a KAT100-1 tuner that you're looking to sell, please let me
know!

Thanks,
Mike NJ2OM

Re: [Elecraft] How to allow K3S to feed multiple logging programs on my laptop?

[Ted Roycraft]

Tom,
I use Win4K3Suite which can reproduce K3 serial data and send it to other
applications that would ordinarily expect to connect directly to the K3.
Win4K3Suite works in conjunction with the free utility, com0com, a virtual
comport utility to “connect” com ports to each other.  The documentation of
Win4K3Suite explains how to do this. I don’t use either ACLog or SKCCLogger
but if all they need is a connection to a K3, I think it has a decent
chance of working for you. I use it with CWSkimmer, LOGic 9, and a home
brew application.

See Win4K3Suite -
https://va2fsq.com/wp-content/uploads/Win4K3Suite-Documentation-v1.45.pdf

com0com -  http://com0com.sourceforge.net/

It might take a couple of tries to make it work but it does a good job For
me.

Check out Win4K3. It does that and much more. Well worth the asking price
in my opinion.
You can download it as a trial. If you like it, you just buy a license and
apply it - no need to reinstall it.

My advice on this is to ALWAYS confront the issue BEFORE buying the

we should approach the issue. Put the onus on the vendor/installer, rule 
out those who give a blank stare or don't want to learn or to do 
anything about it.


And get it in writing -- if it isn't quiet, remove it and provide full 
refund. And if it was replacing an existing system, restore that system, 
also at no cost. When we insist on these provisions, the good vendors 
will figure out what they need to make it work, the losers will vanish.

Of course the pressure should be at the design stage, not the retrofit
stage, but good luck getting that to happen.  The first thing is to get
the manufacturer - or the industry as a whole - to admit that there's a
problem.  Good luck on that one, too.  We've fought that on the
susceptibility-to-unwanted-pickup aspect for decades with very spotty
results.

[Elecraft] Quiet Ductless HVAC System

[Andy Durbin]

"Just as other appliances sold these days with a motor i.e. washing machines, 
dishwashers...  while digital control may add nice features, the noise 
generated can reduce operator pleasure (or operating hours)."

It's not a new problem.  My over 30 year old Maytag washing machine with crude 
mechanical sequencer is a horrible RFI generator.  Huge noise bursts with every 
motor run period.

I'm glad my 35 year old heat pump is still running.  It's single speed, all 
mechanical timing and control, and RF silent.I have no problem turning off 
the washing machine to operate but turning off the AC is not really an option 
in Arizona.

Re: [Elecraft] Quiet Ductless HVAC System

[Rick Bates, NK7I]

Just as other appliances sold these days with a motor i.e. washing 
machines, dishwashers...  while digital control may add nice features, 
the noise generated can reduce operator pleasure (or operating hours).


Getting any manufacturer to routinely add filtering (even if under $1), 
won't happen without a lot of customer noise in return.  ;-)

Re: [Elecraft] Quiet Ductless HVAC System

[Dave Cole]

Hi Hank,

Happy to hear this!  As a group, ALL Amateur Operators, need to push 
this issue with the install of any major appliance...


You may not get any satisfaction, but some will, it is a statistical 
game...  If enough manufactures here about RFI issues, they may start to 
think it is harming sales, then they may well start dealing with this on 
a proactive basis, as opposed to the reactive basis now in place.


I am pretty sure some Solar Companies are already doing this, as I got a 
cold call from one a few years ago in the Oregon area wanting me to come 
out to their assembly plant and look over a few of their systems they 
had set up for RFI testing!


We IDed a number of RFI issues.  I brought a boat load of ferrite 
material with me, and was able to quiet down most of the RFI issues.


They took notes on the material I used, and what I did to quiet things 
down.  I assume they either add them proactively, or add them as 
needed...  Whatever, the outcome was positive RFI wise.


I also pointed them at Mike G, and Ed H., at the ARRL labs, and I assume 
some discussions went on there as well.

Hi Albert,

Here are a few suggestions...  When I added my furnace, I made it part of the 
purchase contract that there was to be no new RFI.  This makes the vendor very 
careful.  Tell them it is a showstopper, and they will be responsible for RFI 
removal if RFI comes with the new purchase.  Get it in writing if possible.

Insist they call the manuafacturer and ask about RFI for the unit you are 
considering, and are there RFI kits for that unit, PRIOR to your purchase...

Be careful assuming brand and model numbers will remain RFI quiet over time.  
Vendors change parts, and circuits, within a fixed model number all the time... 
 What is RFI quiet today, may not be RFI quiet tomorrow...

Take measurements first, before the install, and after install.  Use this 
process:

https://www.nk7z.net/sdr-rfi-survey-p1/

It is part I of III in a series on using an SDR to model your RFI environment.  
Perform the tests, save the results, then run them all again after install...  
I run a full sweep once a year here, and keep the results...  Also see my March 
2020 article in CQ on this subject...

Good luck, and good for you for looking at this early!!!

Re: [Elecraft] K3 on battery?

[Nr4c]

It works ok until the battery gets to 11 Bolts under TX. 

Note:  as voltage goes down the current goes up and as voltage goes down the 
IMD also goes up. 

My club uses two batteries on series and a buck converter to control voltage to 
14 volts.

Re: [Elecraft] Quiet Ductless HVAC System

[Dave Cole]

I have two goals in talking RFI to the vendors, and manufacturers...

1.  Make both the vendor, and manufacturer aware RFI issues may exist. 
This might help the next poor sod down the road, in that the RFI issue 
is no longer "new" to either vendor, or maker.


2.  Gets RFI on the table in the event there is RFI, I can say, we 
talked about this, and you said...


In my case, the vendor called the manufacturer prior to signing a 
contract, and the manuafacturer said no issues at all, RFI wise.  They 
were right.  The thing is dead quiet.

[Elecraft] K3 on battery?

[Doug Faunt N6TQS +1-510-717-1197]

How well does the K3 work with lower power supply voltage, such as
from a deep cycle battery after some hours of use?
I'm looking at resurrecting my station for FD, as 1E.
Relearning the K3 would probably be easier than learning the KX3.

Re: [Elecraft] Problems with KRX3A

[Clark Macaulay]

Gareth,

I had a similar problem when my K3 returned from the factory after a few
updates.  In my case, I had to press and HOLD the RX ANT button.  Don't
remember where I read this but it worked.  Toggling this switch changes the
Sub Rcvr between the main antenna and the receive antenna as the signal
source.

The K3 is a remarkable flexible radio.  With that flexibility comes
complexity at times that is hard to fathom--at least for me.

Re: [Elecraft] Quiet Ductless HVAC System

[Gary Johnson]

At our remote site, we have a new Mitsubishi 12000 BTU mini-split. It is 
located right under our 30 ft tower with Yagis and wire antennas. There is no 
detectable elevation of the noise floor nor any buzzing birdies on 160 thru 2m. 
An external thermostat adapter was installed, and on the cable to the 
thermostat I did apply a proper choke, just in case. All AC wiring is in 
Sealtite or EMT conduit.

Exact models are MSZ-GL12NA-U1 - indoor. MUZ-GL12NA-U2 - outdoor.

Re: [Elecraft] Quiet Ductless HVAC System

[Dave Cole]

Hi Albert,

Here are a few suggestions...  When I added my furnace, I made it part 
of the purchase contract that there was to be no new RFI.  This makes 
the vendor very careful.  Tell them it is a showstopper, and they will 
be responsible for RFI removal if RFI comes with the new purchase.  Get 
it in writing if possible.


Insist they call the manuafacturer and ask about RFI for the unit you 
are considering, and are there RFI kits for that unit, PRIOR to your 
purchase...


Be careful assuming brand and model numbers will remain RFI quiet over 
time.  Vendors change parts, and circuits, within a fixed model number 
all the time...  What is RFI quiet today, may not be RFI quiet tomorrow...


Take measurements first, before the install, and after install.  Use 
this process:


https://www.nk7z.net/sdr-rfi-survey-p1/

It is part I of III in a series on using an SDR to model your RFI 
environment.  Perform the tests, save the results, then run them all 
again after install...  I run a full sweep once a year here, and keep 
the results...  Also see my March 2020 article in CQ on this subject...


Good luck, and good for you for looking at this early!!!

Re: [Elecraft] Problems with KRX3A

[Grant Youngman]

Have you checked the installation of the receiver module?  Meaning that the two 
small riser modules that it plugs into are properly seated to the main RF board 
and the KRX3.  I had a dead sub-receiver problem once.  I had been in the radio 
at some point to install an update.  When reinstalling the KRX3, I had pinched 
one of the coax cables that’s in the vicinity of the riser nearest the front of 
the radio and pulled the cable out of it’s socket when reinserting the KRX3,  
far enough not to work, but not so far that I noticed it until the next time I 
tried using the sub.

Just one more idea of something to look at.

Ok, it sure would have been an easy fix.

It may be time for an email to Elecraft Support if you hadn't sent them

I hope it turns out to be an easy fix.

Re: [Elecraft] Problems with KRX3A

[Gareth M5KVK]

I tried that, Richard.
ANT definitely says MAIN but still no signal.

Gareth,

Try this.

- Turn on the sub receiver by pushing sub
- Push and hold B Set so the display shows b set
- Be sure the ant shows Main and not AUX.  If it shows AUX push the ANT 
button to toggle between the two.

May not be the problem but I've found for some reason my sub receiver is 
on the Aux antenna.  My rig doesn't have the ant tuner either.

Re: [Elecraft] Problems with KRX3A

[Gareth M5KVK]

Thanks for that extra instruction. The manual omits the ‘Tap  MENU to exit 
MENU’ instruction, so I was looking for SYN on the config menu.

Makes no difference though, the values for SYN1 and SYN2 are OK, but there’s no 
signal from the SUB.

Re: [Elecraft] Quiet Ductless HVAC System

[Art Greenberg]

Albert,

I have an 18,000 BTU mini-split cooling my wood shop and radio shack. I started 
with a high-end Lennox mini-split. When it died out of warranty I could not 
justify the extra cost to go with the same model over a Mitsubishi. No 
detectable RFI from either.

The Lennox was MS7-HO-18P outside and MS7-HI-18P inside.

I'll have to get back to you with model numbers for the Mitsubishi. I cannot 
locate that information at the moment.

[Elecraft] Quiet Ductless HVAC System

Does anyone have suggestions for an RF quiet ductless, also  called a "mini
split" heat pump system. I am in need of a small (12000 BTU) system for the
ham shack. Comments from anyone who has used such a system, or successfully
mitigated RFI on a system would be appreciated. Brand and model number would
be highly appreciated.

Re: [Elecraft] Field Day

[Kevin Cozens]

Conversely activity steadily drops off on Sunday and it drops rapidly
after 1800Z, there's not enough activity to compensate for lost time due
to a late start on Saturday.


The other problem one runs in to are the self-appointed "FD police" who will 
refuse to work you as they will tell you it is past a given time and you are 
supposed to have ceased FD operations.


It happened to me one time. I had a late set up which meant I should have 
been able to run the extra three hours. When I tried to contact someone in 6 
land they refused the contact telling me my time was up. At that point I 
just called it a day.

Cheers!

Kevin.
