Re: [Elecraft] Are Elecraft accepting return to Manufacturer for repairs yet ?

[Eric Swartz WA6HHQ - Elecraft]

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,

Re: [Elecraft] KPA-1500 power supply fan noise

[Eric Swartz WA6HHQ - Elecraft]

Hi Peter,

If the amp is on, there needs to be at least some PS fan activity at a low 
speed to cool the PS in idle. 

What s/n is your 1500? On later s/ns we changed a resistor in the ps fan 
circuit to slow them down a bit more. 

An alternative is to swap your ant 1 and 2 connections, putting the 6m ant on 
ANT 1. Then you can listen to 6m with the amp off.

Re: [Elecraft] OT: Well-being check

[Eric Swartz WA6HHQ - Elecraft]

In the interest of keeping the list from becoming overwhelmed with OT Corona 
virus postings, we ask that outside of official company postings from us, you 
do not post covid-19 / corona virus topics here. 

There are a number of other social media lists and sites, and of course ham 
radio on the air communications, that are more appropriate. 

We hope all are staying well and taking precautions.

Re: [Elecraft] Where is Elecraft Support ?

[Eric Swartz WA6HHQ - Elecraft]

Hi Lee,

We definitely do! :-)

If you emailed later on Friday afternoon or over the weekend, their response 
can be delayed on Mondays as they work their way through the weekend backlog. 

Also our CS team was hit hard by the seasonal flu (-not- the Corona virus..) 
the last two weeks and was down to 50% staffing on a number of days.

Re: [Elecraft] 30 Day Price increase Alert

[Eric Swartz - WA6HHQ, Elecraft]

Clarification on my prior posting:

The price increase note below does not directly apply to pre-orders for the K4. 
We're finalizing pricing now as we get a better feel for parts pricing, tarriffs 
on parts, local assembly cost here etc.  We hope to keep it reasonably close to 
the deposit amounts.


One other item: its a 28 day notice, not 30.  ;-)

Re: [Elecraft] K4 Internal and External display resolution

Yes, in addition to using the VFO knob to change frequency, you can change the 
K4's frequency by clicking on the desired signal with a mouse or by tapping on 
it with your finger.

Re: [Elecraft] K4 Internal and External display resolution

[Eric Swartz - WA6HHQ, Elecraft]

Hi Dave,

The K4's internal LCD has a resolution 1024x600, which is very sharp.

We also demonstrate the K4 with a large external 1920x1080 HDMI compatible 
monitor. Our h/w should support up to 4K external monitors.


Note that rather than just mirroring the internal color LCD of the K4 on the 
external monitor, we can display data independently from the LCD at the same 
time in whatever format we wish, such as the full screen spectrum and waterfall 
display we've been showing at the shows at 1920x1080.

Hi Bob.

Contact support(at)elecraft.com and request the free KPA1500 power supply load

started adding the load resistor to new units some time ago.

Hi Eric,

I was able to tighten those screws a little, but it made no difference. Adding 
ferrites to the control cable near the PS helped slightly, suggesting that 
that is the source. The RF is definitely being received by the antenna, about 
100 feet away: its strength depends on the antenna direction, and it is at 
least 7 dB weaker with a dummy load.


I have submitted a request to tech support.

Very slightly loosening (not too far!) and then firmly re-tightening all four

this connector and the rear panel. (There are lock washers between the nuts

If the screws are loosened too far, you may have to remove the bottom cover

BRC: No...
Me: Why not? I'm about to buy a new radio, and it's down to Elecraft and you

radio, so I'm calling you to see if you'll match that offer. You know, maybe I 
can come over and hang out in your ham station -- you do have a station, don't 
you?-- and your big wig can come out and have a soda with me, and we can trade 
stories and shoot the breeze and then call CQ on 20. Yeah?
BRC: No, sir, I'm sorry.  To tell you the truth... we don't

Me:  Excuse me?
BRC: We see important-looking people pass by all the time, but we don't

BRC: Oh, no. That's not possible. . You see, he doesn't

work.  He does select the knobs that go on the radios, though.
Me: The chief knob-picker, eh? Gee, I was hoping for someone who knows how to 
match impedance, or optimize a sigmoid response. Got any amplifier experts?
BRC: Not really.
Me: AGC gurus?
BRC: Not that I know of.
Me: Anybody who solders?
BRC: Oh, yes! You could have lunch with Maria. She's our absolute best solderer.
Me: Can she dig a signal out of the noise? Does she like hiking?
BRC: 
Me: Never mind. You know, I'm glad I called you. I think my mind is made up. 
Good-bye and thank you!

Re: [Elecraft] Disparity between KPA500 remote utility downloads

[Eric Swartz - WA6HHQ, Elecraft]

Hi Dave,

These are two different programs. The first one you show in the jpg, with less 
color, is the KPA500 utility, which is primarily designed for downloading code 
to the 1500 and reading back status etc in real time. It also has very basic 
remote control.


The KPA500 Utility is downloaded from
https://elecraft.com/pages/firmware-software
under the 'Amplifier Firmware and Software' tab.


The second 'more colorful' program you show on your webpage is the KPA500 Remote 
. It is the full featured remote control program for the KP500.


The KPA500 Remote Software is downloaded from the same
https://elecraft.com/pages/firmware-software
page under the  'Logging and Control Software for the K-Line and KX-Line'  tab.

This is what I get upon downloading the KPA500 utility today..., a stripped 
down gray and white panel showing the essentials of the amplifier parameters:

A month ago I downloaded  (what I thought was the same utility) and I got this

These were downloaded from the Electraft K line utility and firmware download

Folks, we're way over the single topic posting limit here, and the discussion

Lets close this thread now in the interest of relieving our readers of email

Also, please do not cross post to multiple lists as this makes it impossible to

Re: [Elecraft] KPA-1500: Widely varying drive requirement - same frequency, different antenna

[Eric Swartz WA6HHQ - Elecraft]

This is not unusual when the loads presented by the antennas (or tuner)  to the 
amp are different.  This can even be true when the SWRs are identical if the 
actual +/- reactance of one is different than the other. 

This is most noticeable on lower freq bands where the amps gain is typically 
higher.

Re: [Elecraft] K4 Delivery

[Eric Swartz WA6HHQ - Elecraft]

Hi Tom,

I apologize for any confusion on K4 status. We really appreciate the support 
you and others have given us with your K4 orders. 

We’ve been very busy keeping our heads down and working hard finishing key K4 
features and getting everything lined up for production, including getting 
critical long lead parts on order with committed delivery dates. We are being 
very careful about getting this right and not cutting corners. 

I’ll make sure to post updates more often here and via direct emAil to K4 order 
holders as we converge to keep everyone informed and up to date. We’ll also 
make more posts describing some exciting features we are adding to the K4 
design.

We’ll be off line through this weekend at the ARRL Pacificon hamfest.  I’ll 
make sure to post here links to any video interviews we give there on the K4 
and its newest features.

You may have a balun issue. I had problems too until I switched to the 1:1 /

fine for me.  In fact, I made over 200 contacts (FT8, and mostly stateside) on 
160m last week.

The KAT500 is "supposedly" limited to matching up to a 10:1 SWR.  That added 
4:1 balun really brought the 160m impedance down to a manageable (and matchable) level.

My ladder line feed is about 160 feet, then the balun, and finally about 13 
feet of RG8XU to the KAT500.

I also gave the original poster a call and his KPA1500 is OK. He made some new

Re: [Elecraft] AX1 Loaded Whip Antenna - Elevation and

[Eric Swartz WA6HHQ - Elecraft]

Guys - lots of very good info here, but we are beating this into the ground. 

Lets end thread thread for now in the interest of maintaining a reasonable list 
SNR. ;-)

Go out and operate, experiment with antennas, including the AX1, and see what 
has been discussed in this thread is best for you in your operating situations. 
 And of course, have fun!

Re: [Elecraft] KPA-1500 Power Output Variation

Just because the firmware was updated and it is no longer required to have a

Re: [Elecraft] K4 and Linux Infrastructure

[Eric Swartz - WA6HHQ, Elecraft]

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


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


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


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

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

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

Re: [Elecraft] Fan speed

[Eric Swartz - WA6HHQ, Elecraft]

The KPA1500 uses a more aggressive fan speed table for 6M, versus the lower HF 
bands. In general there is more immediate component heating on 6M for a given 
power (especially in the LPF and other areas outside of the PA transistors), so 
we start the fans at a lower heatsink temp.


Also, when using very high dissipation modes like FT8 and JT65 on 6M at 
1000-1500 W, we strongly recommend setting the minimum fan speed to at least 1 
or 2.

Hello Eric,
 Just to be sure, I hope there are two separate RX antenna inputs for
diversity reception on the K4D.Is this true are the RX ANT connectors
type BNC?
*Yes. Each RX in the K4D, or HD, can receive via the two rear BNCs, plus any of 
the three SO-239's if the KAT4 is installed.*

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

*Remove top cover and plug in Dual superhet pcb. No complex disassembly. **

 Thank you for all the good product, excellent service and presence of
the engineering team on the forum.

Hi Bill,

Hello

I am just about to drop a down payment on a K4 transceiver, but first I

have a few questions.

1- does the K4 come with the ATU included?  Why is there a KAT4 on the

pre-order list.

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


  > 2- how many USB ports on front panel?

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

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

comm ports like the K3S).

3- how many SO-239 connectors on rear of K4?  Photo shows 4 but I wonder

if that’s the rear of a K4 or K4D?
All three K4 versions start with one SO-239 for Hf-6M.  Three total when the

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

4- is there I/Q output for either or both VFOs?

Yes, over Ethernet.

5- if I plop down $1500 on a K4 today, can I send the other $2500 prior

to start of shipping and get moved to the 1st shipping group? Or is that a
limited time offer?
As long as we have not filled it up, we'll move you up to the 1st shipping
group.  We'll post when the first group is full, which will happen soon.

subtleties, at whatever level of detail, just standing there, totally
comfortable in this setting, obviously enjoying their time.  It's because
from out of their minds came the design, performance, operation of the K4.
Maybe some other QRO radio manufacturers could do this; I suppose Art
Collins did it.  (I have seen Steve Weber, Hans Summers and Asher Farhan do
it for their QRP radios.)  In my mind, it's obviously relevant to, among
other issues, performance and design choices and rationale, the look, feel
and soul of the radio, logical upgrade paths, logical troubleshooting which
will inevitably be required in the future as it is with any electronic
equipment.  The mental video loop of Eric and Wayne standing there with the
crowd will stay in my memory, to be replayed pretty much every day when I
run my Elecraft radios.

Re: [Elecraft] Elecraft / IC-7610 comparison

[Eric Swartz - WA6HHQ, Elecraft]

Hi Brian,

Its a regular RJ-45 Ethernet jack on the rear of the K4. (I believe it is 
gigabit ethernet..) Usually your network router provides the wifi to connect 
wirelessly in the house (also including a DCHP iP address server.)

Embedding wifi in the radio is problematic as it is a rapidly evolving 
technology with regular changes in security features, speed etc that are best 
handled by router sw  and hw upgrades. Its unlikely wifi will stay constant 
over the radio's life.

Re: [Elecraft] RES: ELECRAFT K3/100 RAFFLE

[Eric Swartz - WA6HHQ, Elecraft]

Hi Erwin,

After some Legal research here, we would like to ask you to remove your raffle 
promotion on the Elecraft email list. Apparently there are a number of U.S. 
states that have different laws regulating international raffles, including 
requirements for local registration and funds deposits etc. It may also be 
illegal in other U.S. states and some other countries


For more details, see:
https://www.lexology.com/library/detail.aspx?g=d1b02670-2df8-4124-ba97-665de0172de8

I apologize for the confusion on this.

(Folks - Erwin is the respected owner of Radiohaus ham radio dealership in 
Brazil.)

Yes, but in those days, there was a lot less electronics in vehicles to 
generate noise, and VHF/UHF is VERY different based on wavelength. What we got 
away with 30 years ago for VHF/UHF is bad practice for HF today. I agree 
completely with all of N8SBE's advice.

Re: [Elecraft] Mobile high power

Re: [Elecraft] KFL3A-400 vs. KFL3C-400

[Eric Swartz - WA6HHQ, Elecraft]

Hi Greg,

Very little. Both have similar passbands and protect the subsequent IF and DSP 
stages from overload by signals outside of their passband.  Note that we also 
cascade the K3 and K3S DSP filtering after the crystal filters to further 
improve the ultimate rejection of the filters.

Hi Ed,

Please email supp...@elecrat.com and they will dig into it immediately to help 
you resolve the problem.


If you can use the KPA1500 utility to download the 1500's config file and attach 
it to that email that will also be helpful.  (They can walk you through that 
procedure if needed.) that file includes both the amps full configuration and 
its detailed fault log.)

Re: [Elecraft] P3 Display issues...

Hi Robin,

Make sure you have the P3 and K3 connected via the 9 pin RS232 cable, and that 
both are at the same baud rate mentioned the manual.


Also, in the P3 menu there is an entry for radio type. Select K3 if it is not 
already entered.

I just cannot get this to work for me. I am looking at my P3 connected to a K3. 
It is connected between the IF In on the P3 and IF Out on the K3. When looking 
at the P3 display, on all frequencies, I do not see the actual frequency of the 
VFO, I see 0, for example to top line has -25.0 0 +25.0.

  


On top of that, when I use marker A and move it and press the QSY, nothing 
happens. What am I doing wrong. The User Guide just says how it should work, 
but not why it is displaying 0 as center frequency?

Re: [Elecraft] OT: BIZARRE OFFERING FROM MFJ

[Eric Swartz - WA6HHQ, Elecraft]

Folks - I just been made aware of the posting below.  I am very disappointed 
and distressed that this happened here. 

This extremely inappropriate and racist posting is in direct violation of the 
Elecraft list guidelines, and it is also in direct conflict with the Ethics we 
at Elecraft stand for.  Posts of this type involving both racial and/or direct 
attacks on others, regardless of where they are born or live, will not be 
tolerated here. Period.

As a side note, Martin, the owner of of MFJ, was born in and grew up in 
Mississippi. He earned his engineering degrees from Mississippi State 
University Bagley College of Engineering and also the Georgia Institute of 
Technology. I know Martin and he is an honorable hard working person with 
impeccable values who has our deepest respect. 

Ken, the list deserves a direct apology, as does Martin.

Re: [Elecraft] KPA1500 XCVR FREQ

[Eric Swartz - WA6HHQ, Elecraft]

Hi Brad,

I apologize for the confusion on this.

The following K3/K3S menu entry enables the K3/K3S to send out the transmit 
frequency on the AUXBUS cable to the amp and external tuner.


In the K3/K3S KAT3 menu item, tap the 1 key to set it to "KAT500=Y".

It’s documented in the current shipping KPA1500 owners manual, Rev B1 (2/12/19), 
on page 20 at the bottom. (Its also on the website.)

I brought my KPA1500 to Lubbock for the CQ WW WPX SSB Contest.  Like a good
Elecraft owner, I checked for firmware updates using the KPA1500 Utility,
downloaded what is actually version 210, and installed it.  Next, I checked
the integration with the IC-7610, KPA1500, and antenna switch.  Much to my
chagrin, the KPA1500 did not understand CI-V frequency information above
3800 KHz and throughout the 160m band!  My next thought was to panic, but
good Air Force troubleshooting techniques came through.

The antenna switch understood the radio, but not the amplifier.  It worked
in the ARRL DX SSB Contest.  Loading an previous configuration did not
change the symptom.  I downloaded version 207 and that fixed the problem!

BTW, I downloaded version 210 three times and the same symptom occurred with
each.  I tried all other HF bands without failure.  I suggest a quick look
by someone who understands (wrote) the update.  As long as you stay below
3800 and don't use 160m, you won't experience this problem.  Of course, the
KPA1500 frequency counter took over, but that is not "smooth" at full power
and I don't like red LED's shining in my face.

73, and good luck in the contest!  Bill, K8TE

Re: [Elecraft] For Sale Post From NF5S

[Eric Swartz - WA6HHQ, Elecraft]

Folks - If you suspect fraud or a problem with a for sale posting to the list 
like the one below, please email me as the moderator instead of posting to the 
list. Or if I am unavailable, email sa...@elecraft.com and we will look into it


In this case the for sale email below appears to be legitimate. The email 
address in the posting, davbar...@comcast.net , matches our records here for the 
callsign and name listed in the for sale email below.
And that person is a long time Elecraft customer who did purchase a KX3 and PX3 
from Elecraft some time ago.

Re: [Elecraft] KPA1500 v. 2.10

[Eric Swartz - WA6HHQ, Elecraft]

Yes, we agree - the delay and averaging for forward power for just the LCD 
display was incorrectly set to too low of a value in 2.10.


Fortunately this is only a LCD display issue and does not impact the Power/SWR 
bargraph or internal operations of the amp.


We'll get this fixed in a new f/w update this week.

Of course, direct emails with suggestions to both of us are always welcome! :-)

Re: [Elecraft] KPA1500 temps

[Eric Swartz - WA6HHQ, Elecraft]

Hi Cort,

This is totally normal for the amp in high duty cycle carrier modes like RTTY.  
Also, it will automatically protect itself with margin if the temp at the PA 
transistors gets too high.

I love my KPA1500 but I am somewhat concerned with the temp indicated on

is high. I also have a small probe on the top vent which shows 120 deg F
exhaust temp which is not bad. Should I be concerned here? I am also a
big fan of external fans. My previous amps all had external fans which
helped thinking about putting several small fans along the bottom
front and maybe on the top vent to aid in moving exhaust air away. Good
or bad idea? Any ideas or thoughts would be appreciated. Thanks 73's

Re: [Elecraft] Bouvet

[Eric Swartz WA6HHQ - Elecraft]

Folks,

This remote station dxcc (or contesting) operation ethics and policy pro/con 
thread is now closed. 

As regularly noted here previously, OT amateur radio policy, ethics, and 
related topics, even though they generate passionate opinions, are to be 
discussed elsewhere. These are endless pro/con discussions that can consume an 
incredible amount of list bandwidth from a limited number of posters, 
overloading our other list readers

In the interest of keeping the Elecraft list readable, without posting volume 
overload, and interesting to the vast majority of our over 7000 direct 
subscribers and users of Elecraft gear, these topics are better pursued on 
other forums.

Re: [Elecraft] FT8 Power Level thread..

[Eric Swartz - WA6HHQ, Elecraft]

Folks - The pro/con appropriate power level discussion on FT8 is a repeat of a 
huge prior thread. (Search the nabble archive at: 
https://elecraft.com/pages/community  )


Let's end the thread for now to avoid this one expanding any further. Unlike FT8 
we need a fairly high signal to noise ratio here.  ;-)


In general, please try to avoid getting into arguments on the list over what is 
the 'proper' power to run for any mode of operation. Like politics, these 
discussions can be endless with strong options on every side that can easily 
take up too much list b/w.

[Elecraft] KPA1500 F/W 2.09 Beta released. Also new KPA1500 Utility.

[Eric Swartz - WA6HHQ, Elecraft]

KPA1500 F/W 2.09 Beta has been released to the elecraft website. It can be 
downloaded from the support f/w- s/w page in the K-Line\KPA1500 section.


F/W 2.09 provides a significant improvement in ATU tuning results. It also an 
improves the communication of current radio frequency between the K3/K3S and the 
1500 via the AUX cable. For those of you upgrading from 2.0, see the full 
release note list on the Support Firmware and Software page link below.


Both of these issues were highlighted in the recent "KPA-1500 tuner question" 
thread on the Elecraft email list. Our thanks to Scott-K9MA, Walt-WA1KKM, our 
regular KPA1500 Field Testers and others who have helped us quickly address 
these issues.


We also have a new KPA1500 Utility (Windows Version 1.19.2.21) on the same 
KPA1500 page. Mac and Linux versions will appear soon. This utility version has 
several improvements and also fixes a bug where the erase ATU memories Utility 
button did not always perform the erase. (The erase always worked when done 
directly from the KPA1500 front panel menu.)



The Support Firmware and Software page can be found at:
https://elecraft.com/pages/firmware-software

The new KPA1500 Utility, 2.09 beta instructions , release notes and a link to 
the beta download zip file are at the lower part of the KPA1500 section.


For those who are familiar with the beta install process, the direct link to the 
2.09 zip file directory is:

https://ftp.elecraft.com/KPA1500/firmware/beta

Please, no more 'last word' posting on this topic.  20 posts is well over a

I suspect this topic is overloading many of our other readers on the list. Just 
remember - every email posted here goes to close to 7000 direct email readers,
