Re: [Elecraft] Current Flow on Copper Strips - a Question

[Martin Sole]

I go for the Polyphaser approach. I have used and installed their PEEP 
system on multiple sites here in Thailand. High exposed sites with a lot 
of lightning. Notable over the 20 years since the first one was 
installed there is significantly higher equipment reliability of 
equipment at those sites and none of what were historically regarded as 
"typical regular failures".


The PEEP system tries to keep any surge energy outside the building. I'm 
a firm believer in not letting it inside any more than is absolutely 
unavoidable. In a lot of cases once it gets in the building it is highly 
unpredictable. Think 4 inch hole burned in pcb back plane, steel rack 
cabinet door and vapourised wall mounted fire bell.


The whole sites have very good protection systems designed primarily 
around FAA-019E standard, though I would agree with Polyphaser that some 
of what is contained in that standard is not always ideal. A lot of 
historical convention gets passed on unquestioned into some of these 
standards over the years it would seem.


Regards
Martin, HS0ZED

reference not shown) the current flows primarily along the edges, where it
is surrounded by the smallest amount of flux, and the true or effective
resistance will be high because most of the strip carries very little
current.  (A reference to the missing figure) makes clear that it is not
the amount of conductor surface that determines the resistance to
alternating current but rather the way in which the conductor material is
arranged."

Re: [Elecraft] KX2 Serial Adapter Driver?

Rick,

Go to the FTDI wesite and download and install the drivers.
Do not let Windows try to find the drivers on its own.

Go to Elecraft website, DOWNLOADS ( firmware) and look for the Utility. Near

[Elecraft] Potential KX3 issue

[Bob N3MNT]

Powered up my KX3 ( SN31XX) tonight for evening net and noticed what appeared
to be an overheated component smell on the left side of the radio after
about 6 mins. Never saw smoke.   Radio performed normally and after shutting
down and opening it I did not immediately see anything.  PS was 13.9V and
rcv current was about 0.2A.   Any suggestions on where to look.

Re: [Elecraft] Second speaker just turns off K3S

[Bill Johnson]

Just a thought.  I struggled with the speaker issue with the USB connection to 
my PC.  Turns out my PC recognizes the KS3 as another input and creates all 
kinds of havoc causing inability to control the volume, etc.  I looked at the 
speakers and then at the audio mixer and noted the WIN 10 OS was seeing the USB 
connection and was adding the computer audio to the equation.  I opened the 
mixer on the lower speaker taskbar icon, right clicked, and then muted the 
microphone (USB  Audio CODEC0 and problem solved.  This was really a challenge 
for a bit.  I generally don't have the USB output from the K3S plugged in to 
avoid some other issues, so memory served me correctly.  I have a separate set 
of speakers for the PC and another for the K3S, that IS THE PROBLEM for me. If 
you don't use this set up, no issue.  But IF you use the PC and the Radio, you 
will get into a mess with separate speaker systems.  Hope that makes sense.

Dave, you dont make any mistake. 
This happen also to me. 
I have a K3S with two Elecraft SP3 speakers and P3.
I havent understood why the K3S change from 2 SPKR to 1 SPKR. 
But now I know that when the right speaker cease to work i should open CONFIG 
and reset it to SPKR 2 becouse it had changed to spkr 1.
At first I though that it was rfi, but rfi doesnt change config menu, after I 
thought that it was reprogrammed when I opened  WIN4K3Suite, but it happen even 
without using this program.
I haven't understood why it happen. 
Sorry.

Re: [Elecraft] Elecraft Digest, Vol 168, Issue 30: current flow on copper strips

[Alan B via Elecraft]

My thinking is the current density is uniform in the outer surface of a round 
tube falling according to skin depth at that frequency. At higher frequencies 
there is no current on the inner surface so whether they touch when squashed is 
immaterial, no current there anyway.
What is relevant is the shape of the magnetic field as the tube is 
progressively squashed. As it gets flatter the current distribution moves 
closer and closer to that of a strip. There are no sudden effects.

Re: [Elecraft] PX3 computer interface to KX3

[Nr4c]

But it doesn’t the P3 talks to the K3 at 38,400.  Weird things can happen when 
mixing nauseates. Why ask for trouble. 

BTW: My K3S came defaulted to 38,400. 

I think the 4800 on the K3 was a carryover from K2 days.

Re: [Elecraft] PTT KEY

[Nr4c]

The PTT part of the “PTT KEY” setting can be used to turn ON the transmitter 
for RTTY (AFSK) and other digital modes. Use either RTS or DTR for this. The 
KEY portion is used to send CW (Morse code) either with the key input or paddle 
input.  You will need VOX set to ON for this to work. Use which-ever of DTR/RTS 
you don’t use for PTT.

Re: [Elecraft] Second speaker just turns off K3S

[Mike Cox]

I had this issue also but I've not seen it happen since loading beta 
firmware 5.64 (which has an adjustment to fix this). It's caused by an 
over-current condition sensed by the K3 when both audio channels are 
loud enough to cause brief over-current conditions.


Good luck!

Mike, AB9V

Re: [Elecraft] KPA1500 PS Fan

[Torrey Mitchell]

My #52 KPA-1500 power supply is placed front panel down on a small book on the 
floor rug to protect the protruding LED lights.  It is placed about 3.5' away 
from my left ear with the top of the PS facing away from me.  The result is 
that I can barely hear the PS fans and often forget that the KPA-1500 is 
running.  The amp itself is sitting on top of my Alpha 9500 and is silent.  The 
fans never turn on with my use of the amp.  The KPA-1500 PS fans are definitely 
quieter than my Alpha 9500.  I did replace the 9500's external fan to a much 
quieter one after I bought it 4 years ago.

Re: [Elecraft] KPA 1500 #106 and 107

[Bob via Elecraft]

Interesting.

I have SN107.  It was received on April 21st a full 6 days before SN106.  Both 
cross country shipments.  My shipping notice from Elecraft was on 19 April and 
was shipped via USPS Priority mail.


Just for comparison I was about 18 hours into the 24 hour "Early Notification" 
group and purchased online.   Same 12:54PM PDT time as Jim.  He, I guess was on 
the phone while I was Online.


Not to start the UPS verses USPS war again but am curious if that is the 
difference.

Untried as of today.  Waiting for a new 220 volt  right angle plug so desk can 
get a few inches closer to the wall.

Yes, it is as awesome as we have been told.  Thank you, Elecraft!

One question-the status of the KPA 1500 is listed on the K3 screen as KPA
500.  Is there a way to change that now, or will that be in another K3

Re: [Elecraft] Samuel Morse's birthday (Friday, April 27th); good excuse to break out your old hand keys

[Fred Jensen]

Ahh yes, if life were fair, it would be the American Vail Code.  Unlike 
Sam, Alfred had access to the family machine shop, was an accomplished 
machinist, and could build just about anything.  He even crafted his 
code so the most prevalent letters in English have the shortest codes.


In the mid 19th century, a wagon train was formed [in St Joseph MO, I 
think] for the trip to California led by a fellow named Donner.  It was 
a hugely dysfunctional group from the start, a homicide before they left 
and several more on the way.  Unlike the others, they managed to tee off 
the Paiute Chief near Pyramid Lake in NV, split up amid huge arguments, 
and, without guides [pissed off Chief, remember] were wiped out in the 
winter snows crossing the Sierra Nevada.


Conversely, the Stephens group, formed up, made good time, followed the 
advice of the Paiute guides provided by the Chief, and arrived in 
Sacramento with more people than when they left [several babies born on 
the way].  They spread out over northern and central California, were 
instrumental in founding several towns which became cities today, were 
active in government, and began some of the agricultural industry that 
marks the Central Valley today.  Legend has it that Stevens Creek in San 
Jose is named for their leader, misspelling his name in the process, 
although that may be urban legend too.


So what is the pass over the Sierra Nevada [originally the Lincoln Hwy, 
then US40, and now I-80] named for?  If life were fair, it would be 
Stephens Pass with Stephens Lake at it's eastern base, after a truly 
successful example of the western migration.  But life is rarely fair 
and it's Donner Pass and Donner Lake, named after the dysfunctional 
party racked by homicides, dumb decisions and, it is alleged, 
cannibalism, in a futile attempt to survive the winter.  Alfred Vail is 
not alone.

well as the hand key. But it's Morse's name, as owner of the company that
paid for it, on the patents. Sic transit Gloria.

Searching archives, I found a note where Morse urged Vail to increase the

Re: [Elecraft] Current Flow on Copper Strips - a Question

[John Huggins, kx4o]

What's more appropriate for coaxial building entry grounding management?

This wide-strap, allegedly low inductance, approach...

Re: [Elecraft] K3 AR0 & AR1 commands not working

[Rich - K1HTV]

Hi Wayne,

  Upgrading to the latest 5.64 version of K3 firmware corrected the problem. I 
can now change the 'RX ANT' by using the AR1 & AR0 commands.


When I ran the K3 Utility earlier, and checked for the latest K3 release 
firmware release, it indicated that 5.57 was the most current version and that 
is what I had been using in my K3. However, on the 'K3/K3S Software' page it 
indicated that the latest current revision was 5.62 dated Nov 16, 2017 and not 
5.57 that was indicated when I checked with the K3 Utility. Apparently the 
older 5.57 version which I was using did not have the capability of using AR0 
and AR1 commands to control the "RX ANT". With the command working now, I can 
now remotely switch the K3 receiver between the main and Beverage antennas with 
my Android smart phone using the .


Thanks for your rapid and right on the mark solution to my question. My almost 
decade old K3 is performing great. Since its introduction back last summer, 
I've been playing with the new WSJT-X FT8 digital mode. I've been working many 
grid squares, but my primary focus has been chasing DX. Using the K3, running 
75 Watts with an A3S yagi and wire antennas, the K1HTV FT8 DXCC country totals 
presently stand at 214 worked and 201 confirmed. Thanks to Elecraft for 
producing such a great, high performance radio.

Re: [Elecraft] Odd problem

[Mark E. Musick]

Hi Steve,
It could be some corrosion on the pins connecting the RF board to the front 
panel.
I had K3 s/n 3505 and it still had the tin pins not the gold ones. When I sent 
it in for updates before selling it to my brother-in-law they replaced the 
pins. I had never had any trouble with it. It seems it is standard procedure 
when an early K3 arrives for updates the tin pins are replaced with gold pins.
You can get the gold pins from Elecraft and replace them yourself.
Sometimes, just removing the front panel and replacing it wipes the pins enough 
to eliminate erratic problems.
One of the Elecraft techs told me that production with the gold pins started in 
the s/n range 4000 to 4100. I can't confirm that, but I would take the tech's 
word for it.
Don, W3FPR may be able to verify some of this.

73,
Mark, WB9CIF

I have K3 s/n 3400 plus which I’ve owned since. I have come across an odd 
problem. Occasionally when tuning across any band, the display suddenly jumps 
from 14023 to a frequency in the 80-100 MHz area. The only way to fix it is to 
turn the radio off and then back on. Of course, it is an intermittent 
condition. Doesn’t happen all the time. Any ideas?

So where and when might we find you?? Can I still use my keyer?? My hand
key looks like a work of art but is so clunky even Alfred would have
rejected it.? Sam is reported to have been so distraught that his
numerical dictionary was being rejected in favor of "copying by ear"
that he took to bed for several months.? Sadly, it wasn't his bed, he
was a guest at a friends house.? We do have a guest room, but need
advance notice should you plan to become equally distraught.? More than
a day or two and we'll have to schedule a trip to Costco.
Granddaughter's track meet is canceled on Fri, I will have time.

Re: [Elecraft] Samuel Morse's birthday (Friday, April 27th); good excuse to break out your old hand keys

[Chris R. NW6V]

Good Idea Wayne!

And I'll remind the assembled masses that the unsung hero in the story of
Morse code was a fellow named Alfred Vail - who played Wozniak to Morse's
"Steve Jobs." Vail pretty much invented the dash-dot code as we know it, as
well as the hand key. But it's Morse's name, as owner of the company that
paid for it, on the patents. Sic transit Gloria.

Searching archives, I found a note where Morse urged Vail to increase the
spacing between the characters he was sending because they were running
together. Imagine that! Morse was the first guy ever to complain about
somebody's fist!

No matter how busy I am tomorrow, I aim to make at least one QSO on this
coming Friday in honor of Samuel Morse?s birth (227 years ago!). I?ll be
dusting off my oldest hand key for the occasion, one with a leg strap and
Levi?s-style button that was used by the South African army circa WW2.

If you have an even older hand key, and you manage to get its contacts
cleaned in time for this auspicious date, please send me a photo of it.
I?ll collect the photos and post them on the Elecraft website photo gallery.

[Elecraft] re PX3 computer interface to KX3

[John Newgas]

I had a similar problem last year when setting up my KX3 which came from a 
silent key with accesory bits missing.  I used a an old USB to RS232 adaptor, 
sourced locally which turned out not to be running at proper RS232 voltage 
levels but closer to TTL.

Different devices are more or less tolerant of variations in voltage levels.  
Without a ‘scope it is hard to check the voltages, so substituting with another 
borrowed known good lead might be a good way to go.

I am still missing the Morse Key and Hand Microphone which can’t be found :-(

[Bonjour de Marc ! , F4TXR]

Hello everyone ,
My K3 does not work properly in tuning,
I explain myself, even on fictitious load in a totally random way, it 
happens to me from time to time on the bird in series between 
transceiver and charge to me well out 100 w my with many tunes,
I have a lot of ros back during the tests, and from time to time he 
finds the agreement!

What can happen?
Thank you all for your answers ,
