Re: [Elecraft] KXUSB pinout

[Don Wilhelm]

The cable shown in the XG3 manual can be ordered from Elecraft as the 
KXSER cable.  Or it is easy to build your own if you have the proper 
connectors.  The KXUSB has the same pinout at the KX2/KX3/XG3 end, but 
plugs into a USB port instead of a serial port.

The tip(1) is TX and the Ring(2) is RX... and well you guessed it... the
Sleeve(3) is Ground. So on a DB9 (D-Sub) connector, pin 3 goes to the Tip,
Pin 2 goes to the Ring and Pin 5 to the Sleeve.

[Elecraft] KXUSB pinout

[Mike Short]

I need the pinout for the KXUSB cable, and can't seem to find anything on
Elecraft website.
I need to make an adapter to use the KXUSB cable with a K3.

Thank you, Jim.  I was going to refute some of the comments by K4TAX and

misinformation that shows up here.

Re: [Elecraft] Off-Topic: Your advice/suggestion about antenna

[Lyn Norstad]

Bingo!  One simple post, Bob, and you've covered pretty much everything anyone 
needs to know about wire dipole-type antennas.  This is exactly the process I 
worked thru in deciding to build mine last year, with one embellishment - and 
that was to fine tune the size (I had 400 feet to work with) based on the 
particular frequency on which I wanted it to actually be a 1.25 wavelength EDZ, 
for maximum performance on 3.5 MHz (360 feet).
Like you, I am feeding it from the KPA/KAT500 but needed to use a short run of 
coax into the attic in order to connect to the balun, which is right above the 
shack ceiling.

At the balanced line feedpoint (I am using approximately 160 feet of 600 ohm 
open wire “TrueLadderLine”) I measured the impedance with an analyzer across 
all bands 160 – 6m and calculated that I needed a 4:1 impedance transformer in 
order to present a workable match to the KAT. But I also wanted a 1:1 Current 
Mode balun to reduce common mode issues.  Coincidentally at just that time, 
Balun Designs was developing a hybrid balun that actually incorporated both 
into one package.

I couldn’t be happier with how this all came together.  It is broad banded, 
visually acceptable and most important a great performer.

feed and a suitable balun can be matched on all bands, 160M - 6M with 
the tuner in the K3S or the KAT500.There are no magic numbers

There are two questions to answer:

(Q) How long should the antenna be?

(A)  As long as one has for available space.

(Q) How long should the feed line be?

(A) Long enough to reach from the feed point to the station operating 
position.

Now, the length of the wire is relative, being the most one can put up 
in the clear.  The feedline, be it true open wire of about any impedance 
or ~450 window line or 300 ohm transmitting twin lead is all that is 
necessary.

Agreed, some combinations of lengths are more difficult to match.  If 
this occurs, then add some 4 to 6 ft of feed line length, or add 4 to 10 
ft to antenna length.   Or shorten the feed line length.   The point 
being, if one can attain a 2:1 match or better it will radiate quite 
efficiently.  If your amp won't tolerate this, then a bit more attention 
to length is required.

The topic of what balun to use is an extensive discussion.   Most baluns 
are OK, while some are just purely awful.  Some may not alone provide 
the necessary common mode current rejection.  Power rating of baluns are 
for a MATCHED condition, to which we most always use them in a highly 
unmatched condition.  Thus the suggestion is one consider a much higher 
power rated balun than one intends to run.   My reference to balun usage 
and design is https://www.dj0ip.de/balun-stuff/.

The issue of using a balanced feed system is much easier than the "old 
ham lore" will stipulate.  Just use common sense.  It ain't rocket 
science folks,  nor does it require a Ph.D to make it work and work 
quite well, I might add.

Yes, it is very much OK to bring the balanced feed line all the way to 
the operating position where it then attaches to the balun of ones 
choice.  It is not necessary to have the balun outside and bring the 
feed point in via a length of coax.  If one is going to use open wire 
line or balanced line, then don't screw up the system by introducing a 
length of coax to go from the station to the balun in the outside 
world.There will be an unbelievable amount of high SWR on that coax 
{and equal amount of loss} and likely a high amount of common mode 
current.  Do it correct the first time, enjoy the very favorable 
results, and forget about the "old ham lore" for it is not correct!  
I've only been doing it this way for some 50+ years.

I sit here today with a very modest station.  Then antenna is a 256 ft 
center fed wire with 450 ohm window line. The center of the antenna is 
50 or so feet and the feed line is what ever it took from a 100 ft roll 
to get from the feed point, through the attic eve, drop down through the 
ceiling to the operating position. There was about 25 ft of 450 ohm 
window line left over.  I easily work  all modes and frequencies 160M - 
6M  up to 500 watts from my KPA500 and KAT500.   The antenna and feed 
line have been in the air and in place for 10+ years and I expect it to 
last longer than I do.

Yes, when it rains or snows the SWR goes up, but so what?   That is what 
the dang tuner is for and it does an excellent job with just the touch 
of a button.

If you only have 90 ft for the antenna, that's OK,  If you only have 55 
ft for the antenna, that's OK.  The feed line goes from point A to point 
B, whatever that length might be.  Shorter lengths of antenna become a 
real challenge to get a good

Re: [Elecraft] Shipping Status updates

[Eric Swartz]

Hi JC and everyone on the list,

I apologize for not replying earlier today. As you might expect, we have
been extremely busy adjusting our operations to the announcement from Santa
Cruz County to 'Shelter in Place'. Fortunately, we have been anticipating
this possibility coming to our area, both from ongoing news coverage of the
coronavirus spread and more recently when the counties in the S.F Bay Area
to our north announced their own Shelter in Place order. It has been a very
busy number of days here at Elecraft H.Q.

Yes we are still alive and in operation, albeit with the majority of our
employees working from home. We are just about to release a more detailed
update on our web page and via direct email on this.  I've copied it below
for everyone here to read.

Feel free to ask me questions here or via direct email. I may not respond
immediately, but I'll try to answer as much as I can.

73,
Eric
*elecraft.com *


Elecraft's priority is the safety and well-being of our employees,
customers and the community in which we live and work. We wanted to reach
out and make sure that all of you are staying safe as well as share a few
of the steps we have taken to ensure we are able to protect our colleagues
here at Elecraft while maintaining a high level of support for all of you.



*Santa Cruz County Shelter in Place *

Santa Cruz County has issued a three-week "shelter in place" order from
3/17 through 4/ 7 to guard against the further spread of the Coronavirus.
Residents have been ordered to “shelter in place” and refrain from all
non-essential activities outside of their home. Telecommuting from home is
encouraged. Employees can travel to work to retrieve equipment and
documents needed to telecommute, and companies are allowed reduced staff
on-site to support telecommuting along with protection of inventory,
security and some other business functions.



*What is happening at Elecraft*

Sales and Customer Support are setting up to take calls to Elecraft from
their home offices during our normal work hours.  We will be trying our
best to maintain a business-as-usual service, but, inevitably, you may hear
kids laughing or dogs barking in the background during a call with us.  We
appreciate your patience and understanding as we navigate the current
reality together with all of you.



We will continue to ship products that we have in stock.  Items that we do
not have in stock will be shipped later in April when we are able to
resume full manufacturing.



All of our engineers are able to continue their work on projects off-site,
including K4 development.



Manufacturing and production at Elecraft will continue when Santa Cruz
County's "shelter in place" is lifted.



*Placing Orders*

You may place orders online at elecraft.com or by calling Sales at
831-763-4211.  We will continue to ship products that we have in stock.
Items that we do not have in stock will be shipped later in April when we
are able to resume full manufacturing.  We will not process your payment
until we are able to ship your order.  If your order is not shipped within
a week, we may have to contact you for payment information since our system
does not store credit card numbers.  You may also place a note on your
order form to process your payment immediately, and you’ll receive a
shipping tracking number as soon as we’re able to ship your order.



If you have any questions regarding your order or about any of our
products, please feel free to call us at 831-763-4211 or email
sa...@elecraft.com or supp...@elecraft.com



All of us at Elecraft hope you stay safe and healthy, and we thank you for
being a part of our Elecraft Family.

[Elecraft] Off-Topic: Your advice/suggestion about antenna

[Bob McGraw K4TAX]

As discussed below, what ever you wish to call it, the antenna that is, 
being:   a G5RV, a double Zepp, an all band antenna, a center fed dipole 
and a few more brand names, the center fed dipole with with a balanced 
feed and a suitable balun can be matched on all bands, 160M - 6M with 
the tuner in the K3S or the KAT500.    There are no magic numbers 
regarding lengths.


There are two questions to answer:

(Q) How long should the antenna be?

(A)  As long as one has for available space.

(Q) How long should the feed line be?

(A) Long enough to reach from the feed point to the station operating 
position.


Now, the length of the wire is relative, being the most one can put up 
in the clear.  The feedline, be it true open wire of about any impedance 
or ~450 window line or 300 ohm transmitting twin lead is all that is 
necessary.


Agreed, some combinations of lengths are more difficult to match.  If 
this occurs, then add some 4 to 6 ft of feed line length, or add 4 to 10 
ft to antenna length.   Or shorten the feed line length.   The point 
being, if one can attain a 2:1 match or better it will radiate quite 
efficiently.  If your amp won't tolerate this, then a bit more attention 
to length is required.


The topic of what balun to use is an extensive discussion.   Most baluns 
are OK, while some are just purely awful.  Some may not alone provide 
the necessary common mode current rejection.  Power rating of baluns are 
for a MATCHED condition, to which we most always use them in a highly 
unmatched condition.  Thus the suggestion is one consider a much higher 
power rated balun than one intends to run.   My reference to balun usage 
and design is https://www.dj0ip.de/balun-stuff/.


The issue of using a balanced feed system is much easier than the "old 
ham lore" will stipulate.  Just use common sense.  It ain't rocket 
science folks,  nor does it require a Ph.D to make it work and work 
quite well, I might add.


Yes, it is very much OK to bring the balanced feed line all the way to 
the operating position where it then attaches to the balun of ones 
choice.  It is not necessary to have the balun outside and bring the 
feed point in via a length of coax.  If one is going to use open wire 
line or balanced line, then don't screw up the system by introducing a 
length of coax to go from the station to the balun in the outside 
world.    There will be an unbelievable amount of high SWR on that coax 
{and equal amount of loss} and likely a high amount of common mode 
current.  Do it correct the first time, enjoy the very favorable 
results, and forget about the "old ham lore" for it is not correct!  
I've only been doing it this way for some 50+ years.


I sit here today with a very modest station.  Then antenna is a 256 ft 
center fed wire with 450 ohm window line. The center of the antenna is 
50 or so feet and the feed line is what ever it took from a 100 ft roll 
to get from the feed point, through the attic eve, drop down through the 
ceiling to the operating position. There was about 25 ft of 450 ohm 
window line left over.  I easily work  all modes and frequencies 160M - 
6M  up to 500 watts from my KPA500 and KAT500.   The antenna and feed 
line have been in the air and in place for 10+ years and I expect it to 
last longer than I do.


Yes, when it rains or snows the SWR goes up, but so what?   That is what 
the dang tuner is for and it does an excellent job with just the touch 
of a button.


If you only have 90 ft for the antenna, that's OK,  If you only have 55 
ft for the antenna, that's OK.  The feed line goes from point A to point 
B, whatever that length might be.  Shorter lengths of antenna become a 
real challenge to get a good match on frequencies lower than the 
resonant length but it will work if you can match it.   For get about 
the charts, the computer modeling, and put up what you can, in a 
reasonable fashion, and begin to enjoy ham radio.

Re: [Elecraft] Off-Topic: Your advice/suggestion about antenna

[Dave New, N8SBE]

I'm surprised that no one has mentioned MY favorite antenna(s):


1) A 2-el spider-boom quad at 40 ft., covering 20-6M (including the WARC
bands):


https://www.qsl.net/ei7ba/Cubical%20Quad.htm


2) A ZS6BKW dipole, which is 92 ft. long, includes a 40 ft. window line
section, and then 75 ft. of coax.  I only use it on 30-80M, using the
ATU on my K3S to tune into it:


https://www.amateurradiosupplies.com/product-p/11003.htm


The quad is a pile-up buster, especially on 20M.  It's been up for about
10 years, so needs some TLC, but I'd say that it's held up pretty well,
considering everyone says that quads don't (hold up well).


A 2-el quad performs at or better than a 3-el yagi at low heights above
ground (35 vs 65 ft), and I have the wallpaper to prove it.


The ZS6BKW is up about 35-40 ft. (slopes at one end) and doesn't do so
well for DX, but is a killer for NA contests (NAQP, Sweepstakes, MI QSO
party) from the Midwest.


This all fits on a postage-stamp lot, in a non-HOA  neighborhood.


Ya gotta' make do with what you can get up in the air...

Re: [Elecraft] Case color trivia ...

Search any of the stock image sites for "Digital camouflage seamless

public domain.

You can also use free software such as GIMP to generate your own pattern.
Perhaps using your callsign as a seed for the algorithm.

Re: [Elecraft] KPA1500 SWR Tolerance

[Bob McGraw K4TAX]

SWR only tells a small part of the story.   Remember, most all systems 
measure and display only the ratio of forward voltage to reflected 
voltage on the line.   Thus it has little to do with actual impedance, 
specially in a more common reactive environment.


But for most folks, it is a good indicator of match as long as the 
system isn't too far away from 50 ohms, one way or the other, and there 
isn't too much common mode current flowing.

I've long been aware that my KPA1500 would not run at full power (1.5 
kW) unless the SWR was very low. (This is SWR at the input to the ATU, 
if used.) The current ATU firmware does a pretty good job of keeping 
the SWR below about 1.3:1, which usually is low enough.


In any case, I just ran a simple test on 160, where I have an antenna 
I can easily tune to 1:1, or deliberately higher. The ATU was engaged, 
but it's settings were not changed during the test. The SWR indicated 
was that at the ATU input (amplifier output).  I found that the output 
power remained nearly constant up to 1.4:1, but the current increased 
from 58 to 62 A. (This with no adjustment of the K3 power, though the 
indicated input power varied slightly.) At 1.5:1, the current exceeded 
65 A and the amplifier faulted. By reducing drive, I was able to run 
it at 1.4 kW output and 60 A.


The above is typical of my experience on other bands, etc. The effect 
of SWR on the amplifier, of course, depends on the actual impedance at 
the amplifier, so in some cases it may be more or less sensitive to SWR.


Do others see similar effects?

A station in Barbados (8P6) asked me : “what you got in that car a Henry 2K” ?

[Elecraft] Case color trivia ...

[Ken G Kopp]

Rose found in the course of her case and cover fabricating business that
most "camo" fabric patterns are copyrighted and therefore many fabric
stores don't sell them.

Re: [Elecraft] Shipping Status updates

[Bob McGraw K4TAX]

With the cancellation of the Hamvention,  I'm sure everyone is 
scrambling to make the necessary changes.   Most on line services are 
very active and thus USPS, UPS, Fed-X and others are seeing a much 
higher degree of activity.    I see this with items I have ordered as 
recently as a week ago.    Extended shipping times are to be expected.


Small companies which are ordered to close or have voluntary elected to 
close may not survive.  Economically the next few weeks and months will 
be critical to our national economy.    We wish all the best in the days 
and weeks ahead.

Bob, K4TAX

Re: [Elecraft] Shipping Status updates

[Paul Gacek via Elecraft]

For what it’s worth the southern most “Shelter in Place” county is Santa Clara.

Watsonville is in Monterey county which is south of Santa Clara.

However I’m sure shipping via fedex etc has to have taken a hit.

Buying from Elecraft right now has to help them. Tough times all round.

[Elecraft] Shipping Status updates

[W6IPA]

Hi,

I understand that this is a very challenging time for every company in the US, 
specifically the ones in the counties in the San Francisco area impacted by the 
closures. It would be good to have an update FROM Elecraft on the impact on 
shipping and other operations.
The last update to the shipping status page was on 03/05, and I’m sure many 
things are different now, and some dates already passed.

I’m looking at ordering some equipment and was wondering about what is 
happening.

Thanks.

JC/W6IPA.

[Elecraft] KPA1500 SWR Tolerance

[Andy Durbin]

"The effect of SWR on the amplifier, of course, depends on the actual impedance 
at the amplifier, so in some cases it may be more or less sensitive to SWR."

My limited experience with solid state amplifiers make me believe that 
characterizing the load by "SWR" is not very useful.  The measurements only 
become meaningful if you measure, and report, the complex load impedance.

Andy, k3wyc
