No, it's FAR more complex than that. Horizontal antennas see the 
reflection from the earth as a parasitic element, which adds a complex 
impedance to the equivalent circuit. The reflection, and thus the 
parasitic impedance, will depend on height above ground, the skin depth 
of the earth, and the electrical qualities of the soil.


The ON4UN book, "Low Band DXing," includes a set of very interesting 
plots of antenna impedance as a function of height and soil quality. In 
general, the feedpoint Z of low dipoles oscillates as height varies, 
with the average near 50 ohms, while high dipoles oscillate around 70-80 
ohms. It's easy to see this in the very simple NEC model of a center-fed 
dipole (the model is a wire with a generator in the center of it) by 
varying the height and the soil parameters.


My dipoles for 40 and 80M are up about 125 ft in tall trees, and I have 
lousy soil. The model predicts Z at resonance in the range of 85 ohms, 
and I've measured 88 ohms. I feed them with RG11. Some years ago, I was 
planning antennas for a CQP county expedition in a spot that has scrub 
trees (max rigging height ~40 ft) and lousy soil, but is on a small 
knoll, so the takeoff angle is great. NEC predicted 75 ohms for one of 
them and 50 ohms for the other, so we carried RG8 for one and RG11 for 
the other. When we measured them, they turned out as the NEC model 
predicted.


There are computational tools and instrumentation that one can learn a 
lot from if we use them to study stuff like this. NEC is one of them.

Re: [Elecraft] CWT Calibration

[Rick NK7I]

On the presumption of a worst case (for me) simplex receiver condition 
for the other station, them filtered down to 50 Hz; I use XIT to not be 
zero beat (which used to be expected once upon a time) with no greater 
than 25 Hz offset (stay within that 50 Hz filter).  Then one must only 
look (P3) at the station the DX is currently working to see if plus or 
minus 25 Hz should be used.


Then watch patterns, does the other station move the receiver at all, 
switch plus for minus... is there a pattern?  (Random, never is).  
Paying attention to details means easier success rates.  ;-)


If split, use the same observations, but turn off XIT and use the other 
VFO for TX (allowing you to hear the station being worked as well).  
EVERY operator has a pattern, humans are just wired for consistency.  
Find it, predict it, make that contact.

Can you hear a 25 Hz pitch difference when it's hot on the short wave bands?
If so, congratulations! You can admit it if you used a frequency counter.

In my opinion CWT is a very good tool to get close to another station
quickly. And no one realy no one has complained to me in a QSO so far that I
was 25 Hz away from his transmitting frequency.

Re: [Elecraft] K4 in production

I'm always bemused when a completely 
unexpected series of profoundly affecting 
variables, none of which are from internal 
causes, make themselves a factor in 
development and construction, appear and 
globally interfere with design, 
production, and supply. This fluid state 
appears while a specific completion date 
and time was never assured of, & in 
subsequent conversations with advance 
purchasers. 

As there was never a promised date, there 
is a Pandemic where over 100,000 people in 
the USA alone have already died, 
Manufacturing globally has taken a real 
hit, transportation has taken a major 
blow. I had a USPS 2 day package shipped 
from Michigan on Sat 11 and it is nor the 
16th & tracking shows it just left 
Michigan on route to CT. It may be here on 
Saturday. That'll be a 6 day delivery with 
a 2 day promise. That same kind of delay 
is happening to the construction of the K4 
and any new components are also affected 
in this way. There is no other choice and 
I want it And I want It Now pressure 
doesn't do anything but waste everyone's 
time. It has zero rate on accelerating 
production and if anything, detracts from 
the focus from the principals.

All this takes me back to the bemusement I 
get when reading such comments. Do they 
really believe in this arena it will move 
anything along faster, and if the company 
indeed did rush to complete while not 
having sufficient components in, on time, 
that it would behove the production run in 
any way whatsoever? 

Good friends, chill, this is an 
unprecedented time and Elecraft is moving 
along in the best way to give the best 
product they can do. We'll have our little 
beauties when they're vetted and 
competent. Till then, chill, practice some 
CW Check the antenna connections stop 
thinking of it should have been here by 
now, because it was never promised to be 
here by now. Things are moving forward 
nicely. 

And yes, I dropped the full deposit for a 
K4D and am aware I'll have to wait for the 
HD module to be created. I'm, metal 
detecting, digitizing my stereo collection 
and enjoying the Yamaha on nice days. 
Elecraft is doing their job, and I'm doing 
mine.

There is a very large difference in signal to noise ratios and operating 
power levels between an analog video production facility and a ham 
station. 30-40 dB SNR is great for that broadcast plant, and unless it's 
colocated with the transmitter, far less exposure to RF than a ham 
station running legal limit. In our ham stations, we may need 100 dB or 
more rejection of RF; the 60 dB difference translates to a 1,000,000:1 
power ratio and a 1,000:1 ration of voltage or current.


In addition to my own station, where I do a lot of serious contesting, 
I've long been part of teams that do serious county expeditions, and I 
read a lot to try to learn as much as possible from others who do it 
more, and at a higher level. Two admonitions from these folks who do it 
in the field stand out. 1) If anything is flaky in the station, ALWAYS 
suspect a bad piece of coax or badly terminated connector. 2) Always 
make sure that all connectors are wrench tight.


And I'll add my own -- NEVER use junk connectors or adapters anywhere in 
your station. For RF connectors, that means Amphenol (83-1SP w/no suffix 
for UHF) or used MIL-spec. For audio, that means Neutrik or Switchraft.

Re: [Elecraft] KPA1500 in the IARU Contest Last weekend

[Fred Jensen]

They were around somewhat before the patent in several forms, and they 
were around in 1960, which is the last time I looked hence my estimate 
of 60 years.  Lots of other "balanced" antennas fed with open line were 
also in use commercially during that rough period, they too exhibited 
the same characteristic ... while carefully engineered to be balanced, 
RF currents in the two wires never were exactly balanced, which was the 
original and only point.


I still have an RF ammeter in my junk box, from some airborne WW2 radio 
I think.  It's probably an antique by now.

Can you hear a 25 Hz pitch difference when it's hot on the short wave bands? 
If so, congratulations! You can admit it if you used a frequency counter.


In my opinion CWT is a very good tool to get close to another station quickly. 
And no one realy no one has complained to me in a QSO so far that I was 25 Hz

Re: [Elecraft] Waterproof SO-239 covers

[hawley, charles j jr]

I wiggle the connector as I finger tighten the barrel. The result is that they 
are difficult to unscrew. Also I use a heavy silicone grease on the threads and 
on the back where the barrel contacts the connector. I have never had any 
issues with water in 20 years doing that.

Re: [Elecraft] KPA1500 in the IARU Contest Last weekend

[donovanf]

Hi Skip, 


Conceptionally you're correct about rhombics and V-beams but your time frame is 
way off. 


Edmond Bruce's rhombic antenna patent was filed in 1931. 


www.aktuellum.com/mobile/circuits/antenna-patent 


ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=1685103 


The heyday for the rhombic ran from the 1930s through the 1970s with 
the advent of satellite communications. The 200 foot tower for my 
40 meter stacked 3 element Yagis came from a decommissioned 
Laport Rhombic installed at the NSS receive site in Cheltenham MD. 
We removed it in 1985, but it hadn't been used for years.

Indeed! Probably the least unbalanced of "balanced" antenna systems 
that ever existed were the HF point-to-point rhombics and V-beams at the 
RCA, Mackay, and Marconi shore stations in the first 60 or so years of 
the 20th century. Despite very precise engineering to make them 
balanced, the RF currents in each side of the open feeders were never 
exactly the same. 

As a teenage ham, I tended to think in absolutes and exactitudes. If my 
Heath MM-1 multimeter said the screen voltage was 176.5 V, I believed it 
was, exactly, and if the spec said 177.5 V, I needed to do something to 
"fix" it. If the ARRL Handbook said the two halves of my 40 meter 
dipole needed to be exactly 32.9114 feet, I believed that the antenna 
would not work if I didn't assure my dipole was exactly 32.9114 on each 
side. As I grew older, both in age and ham longevity, I realized my 
Elmer was right when reminded me on multiple occasions, "We're 
amateurs. Most often, 'close' is good enough." 

Seems like many today are convinced that 32.9114 ft will work but 
32.9000 ft won't.

There was one 15K resistor in the two RF bags. But one is required for

Re: [Elecraft] KPA1500 in the IARU Contest Last weekend

[Charlie T]

Yeah, I remember as a new ham of 14, I asked my dad to buy a 50 foot piece of 
RG-58/u at Electronics Wholesalers in Washington DC.
He came home with 50 feet of RG58C/u which has a stranded center conductor and 
a characteristic Z of 53Ω.

I politely asked him to return it since it wasn't the correct impedance.
The counter clerk tried to explain that it was "better" because of  the more 
flexible center and the very slight difference in characteristic impedance 
wouldn't make ANY difference in performance, but he insisted and came away with 
a new piece of RG-58/u.  I think l I used it to string up a 15M dipole between 
our two chimneys.

Never DID get that %$#@ Globe Chief to work on 15 though.
For some reason, it had more output on 14 MHz than 21 even when I had the 
bandswitch on 15M 
My entire Novice career was spent on 40M CW and 2M AM back when Novices had 145 
to 147 MHz.

[Elecraft] Impossible separation - tenuously related to "K4 in production"

[Andy Durbin]

"high enough that if everyone stood 1 meter from everyone else,"

Never mind the math.  Can't you all see that the basic premise is impossible?

It could work if everyone stood at least 1 meter from anyone else.  It could 
also work if everyone stood at least 1 meter from everyone else.  What can't 
work is everyone standing 1 meter from everyone else.   The compressibility 
effect would be horrendous and the resulting spanned distance wouldn't be much 
over 1 meter.  Far short of spanning from Pacific to Nevada.

Re: [Elecraft] K4 in production

Yes, I too have a math degree and the mean population density of 
California is ~98/sq km and yes, all the people in CA could stand well 
more than 1 m apart and no one would need scuba tanks or find themselves 
in Nevada [or Oregon or Arizona or Baja California].  I made it up ... 
it was intended as a joke.  It's a good thing I ended up supporting my

Check your math.  World population is about 8 Billion.  Give everyone a Covid 
distance of two meters, or four square meters per person.  That gives us 32 
billion square meters to socially distance the world population.  California is 
about 424 billion square meters.  Plenty of room for everybody!

I agree completely, but there's a "catch".

Traveling-wave antennas, such as Rhombics, or Beverages, or leaky transmission 
lines, are, technically, non-resonant. However, they can each present a 50 ohm 
feedpoint impedance that is purely resistive, and produce a 1:1 VSWR as a 
result. ;-)

So, whether an antenna is resonant or non-resonant isn't the issue. The issue 
is whether or not a load impedance contains a reactive component. If it DOES, 
then it can never produce a 1:1 VSWR.

Yes, a resonant half wave dipole can have a feedpoint impedance of 5 ohms

Conversely, a non-resonant antenna can have a 1:1 SWR.

Re: [Elecraft] CWT Calibration

[Ingo Meyer, DK3RED]

Hi Wilson,



I have deduced that the bars in the CWT display are 25 Hz apart.
Does anyone know if that's right?


Can you hear a 25 Hz pitch difference when it's hot on the short wave bands? If so, 
congratulations! You can admit it if you used a frequency counter.


In my opinion CWT is a very good tool to get close to another station quickly. And no one 
realy no one has complained to me in a QSO so far that I was 25 Hz away from his 
transmitting frequency.

Re: [Elecraft] K4 in production

[Robert Rennard via Elecraft]

Six weeks ago, my 100 years old Grandmother’s dryer broke down.  My bride and I 
went to Lowes to see what we could find that would be simple to operate, and 
did the same at the local Home Depot.  Grandmother is about 1230 miles from us.
One thing we noticed that was common to all the models in both the big box 
stores was a taped on paper sign reading BACK ORDERED.  We had little success 
trying to get one from either big box website, but did finally get an order 
placed for delivery a month ago.  Grandmother got the new dryer about two weeks 
ago.  Delay after delay.

I think we should realize that a lot of changes have to be made for a company 
to comply with the guidelines and ensure employee safety: workspace spittle 
shields, ingress body temperature checks, PPE such as masks and gloves, and the 
20 questions that should be asked every Monday regarding what employees did 
over the weekend.  Not only does Elecraft want to ship products and complete 
repairs in a timely manner, they also want to avoid jeopardizing employee 
health.  We too should want Elecraft to meet these objectives, particularly the 
latter.

I continue to see the video of some woman ranting about her right to not wear a 
mask.  She is evidently completely clueless about how SARS-CoV-2 spreads.  So, 
you can mock me for wearing a mask, but I hope you won’t have to mourn me 
because someone else did not wear theirs.  Maybe being jailed for involuntary 
manslaughter would wake up the public who think COVID is a hoax.

Re: [Elecraft] Waterproof SO-239 covers

Amen, George, on mating the “tiny indentations.”  It’s easy to ignore this step 
because many hams think they mate automatically as the PL-259 penetrates the 
SO-239.  They sometimes don’t.  The coax itself has to be rotated back and 
forth until the mating can be felt through one’s fingers.  Indentations on 
cheap connectors have minimal mating surfaces or none at all.

Re: [Elecraft] Waterproof SO-239 covers

One problem is that "finger-tight" is not the same for all hams.
The other is the use of off-brand connectors that do not fit well.
The other is that some connectors do not engage the protruding 'tabs' on 
the PL-259 do not seat properly with the indentations on the SO-239. 
Those are the ones for which "finger-tight" is not good enough.


I agree that 1/4 turn is too much - if you can turn it that much, it was 
not properly mated, remove and start again.  Just a slight touch of the 
pliers will make it certain the connector is tight.

Re: [Elecraft] KPA1500 in the IARU Contest Last weekend

[Fred Jensen]

Indeed!  Probably the least unbalanced of "balanced" antenna systems 
that ever existed were the HF point-to-point rhombics and V-beams at the 
RCA, Mackay, and Marconi shore stations in the first 60 or so years of 
the 20th century.  Despite very precise engineering to make them 
balanced, the RF currents in each side of the open feeders were never 
exactly the same.


As a teenage ham, I tended to think in absolutes and exactitudes. If my 
Heath MM-1 multimeter said the screen voltage was 176.5 V, I believed it 
was, exactly, and if the spec said 177.5 V, I needed to do something to 
"fix" it.  If the ARRL Handbook said the two halves of my 40 meter 
dipole needed to be exactly 32.9114 feet, I believed that the antenna 
would not work if I didn't assure my dipole was exactly 32.9114 on each 
side.  As I grew older, both in age and ham longevity, I realized my 
Elmer was right when reminded me on multiple occasions, "We're 
amateurs.  Most often, 'close' is good enough."


Seems like many today are convinced that 32.9114 ft will work but 
32.9000 ft won't.

Few ham antennas are perfectly balanced -- they are often unbalanced

the two halves, other conductors around the antenna, even vegetation. 
And yes, all elements of the antenna system, including the feedline, 
the antenna, and matching at both ends, contribute to the balance of 
the SYSTEM.


THAT'S why it's wrong to talk about "balanced line," using "parallel

Re: [Elecraft] Waterproof SO-239 covers

[Gmail - George]

Years ago in a land far-far away all video coax connectors in Broadcast 
Television were UHF (PL259).
We only tightened them hand (finger) tight. In may places pliers would have 
not fit any way.

In black & white days we would want to be flat from DC to around 8 MHz with 
a smooth roll off to about 15 MHz.
Later in color most of the video distribution amplifiers were flat to even 
25 MHz.

>From the late 60s to late 70s the connector density increased significantly 
and we went to BNC for video & later for even audio when we converted to 
digital audio distribution.

In a typical studio plant any discontinuity in video coax tended to show up 
as a "ghost" in the video in black & white and in color the results could be 
only described as Technicolor gone wrong. We rarely had discontinuities - 
most of the time it was a poorly made connector or center migration due to 
too tight a bent in the coax. I don't ever recall that tightening a 
connector with pliers corrected these discontinuities. We solved the poorly 
made connectors by going to crimp style of connectors.

When I became a Ham after retiring from Broadcasting - I had to go back to 
using UHF connectors. First tool I bought was a coax connector crimp tool! 
Unfortunately I could not afford the $300 to $500 tools for each coax size 
that we had at work. I had to buy a much less expensive tool with 
replaceable dies. Not quite as convenient & easy to use but much more cost 
effective! Then again I wasn't going to be spending hours putting coax 
connectors on cables.

A broadcast plant had many hundreds and probably thousands of uhf coax 
connectors to deal with and a lot of experience in all conditions from fully 
climate controlled (tape rooms) to harsh outdoors on ENG or SNG truck masts 
going 60 or 70 MPH in rain, sleet and snow.
In fact when we replaced a 1,000' tower. We cut off the coax seal on 
connectors that were maybe 20 or 30 years old - the connectors were bright 
and shinny underneath!

Proper installation of the UHF connector is to make sure it is made 
properly, and then properly mated by rotating the coax until the tiny 
indentations on the female are found and mated with the male. Then tighten 
it hand tight. If not indoors then seal the connection.

I must say that over many years and without any ill effect I've never
bought into this idea of Gorilering up a PL259 with pliers beyond finger
tight. A quarter of a turn is an unbelievable suggestion.

Re: [Elecraft] K4 in production

[Don Wilhelm]

All,

The parts may have come in pre-covid, BUT
Elecraft boards are populated at board shops in California, and the 
metal parts come out of another shop in California.


So while Elecraft may be limping along, they are dependent on a variety 
of other California shops which may be shuttered.

Urban myth maybe?


No, misunderstanding/poor way of describing the problem. For good RF 
contact, the entire circumference of male and female connector must make 
solid and continuous contact. This can only happen if the teeth in the 
male connector fit within the corresponding gaps in the female 
connector. If that has been accomplished, wrench-tight may be less than 
a quarter turn, but it also depends on how strong your fingers are, and 
whether you are able to get a good grip on the connector. For example, I 
need more than a quarter turn with pliers in my fairly dense entry panel 
in the wall under my operating desk. And if the teeth are not properly 
mated, it's common to get more than a quarter turn when using the wrench.


Also, I've never had a failure after simply applying a generous wrap of 
self amalgamating tape, nothing else, to waterproof coax connectors. Our 
UV environment is pretty powerful, clear skies and sunshine can turn the 
skin on my head into huge dandruff seven days later after 30 minutes 
exposure.


That depends entirely on the particular tape you've chosen. Some are 
more UV resistant than others.

Few ham antennas are perfectly balanced -- they are often unbalanced by 
their surroundings. For example, ground slope, unequal heights of the 
two halves, other conductors around the antenna, even vegetation. And 
yes, all elements of the antenna system, including the feedline, the 
antenna, and matching at both ends, contribute to the balance of the SYSTEM.


THAT'S why it's wrong to talk about "balanced line," using "parallel 
wire" or 2-wire" line instead.

Re: [Elecraft] FT8 - was "On Second Thought, I'll Take The Stairs"

Sure wish I could put up such a "no antenna" antenna from my apartment

[Elecraft] K4 in production _ Money UPDATE

IF and IF I remember correctly, they (Elecraft) takes not a penny from you
till it is shipped. I know the money is waiting for them as I wait for the
K4.

I'm still happy, wishing I could I could have taken it on the dxpedition,
but it didn't happen either due to Covid-19.
I have a great K3S K-Station setup..
I will have a better K4 K-Station setup when it comes in.

Re: [Elecraft] K4 in production

[Rick NK7I]

"The plan" was to get a tilt tower, so I don't have to climb and that 
works great.


I also pre-paid for the KPA1500 and then once it arrived had to wait (2 
years) for the shack to be built (else no 240V).  I don't regret this 
because Elecraft HAS the reputation for being the best at product and 
service; they understand much better than the other brands.


No one has a guarantee to tomorrow, but there are signs of hope around.

Re: [Elecraft] K4 in production

[WILLIE BABER]

If I had the money to put up in advance I would "front" the money to Elecraft, 
based on the K3. And I did purchased kpa1500 in advance.
I purchased Orion before it was produced based on most of the previous Tentec 
radio too.
But I confess that while I do turn 70 years old in September, I am in excellent 
shape, still climbing towers.  
Time can be an important factor, but who doesn't know that?

Re: [Elecraft] K4 in production

[Rick NK7I]

Given the on/off, cancel/restart mother may I, only with a mask 
situation in CA (often spelled P_O_L_I_T_I_C_S), it's a wonder they're 
doing as much as they have.  That tap dance is on a very thin high wire 
with no net.


Now consider that many parts do not come from the US, some of the 
sources are from countries we're bickering with (see spelling above, 
subtitle tariff), the parts that ARE here can't be put into boards that 
can't be made because other businesses are less 'essential' (defined in 
no law whatsoever)... all resolves to:


They're doing what they are allowed to do under the conditions they 
face.  And doing it well, the Elecraft way.  This'll take a while so 
patience is required.


If you truly feel deceived, cancel your order and let the next in line 
move up a slot.  I'm sure they be appreciative.

Re: [Elecraft] K4 in production

nonetheless, I think we are all hoping for the best with covid (and doing 
what we can to be safe) and vis-a-vis Elecraft.
If anyone thinks that Elecraft is trying to do anything other than their love

paying attention since before the Elecraft K2.

Re: [Elecraft] Waterproof SO-239 covers

[KENT TRIMBLE]

Mike . . .

I think he might have misspoken when suggesting using pliers to effect 
an extra quarter-turn on a PL-259 after first getting it finger-tight.


The "quarter turn" idea most often refers to the trick of backing-off a 
screw "a quarter turn" and then re-tightening in order to break up 
corrosion.  More than one restorer has brought vintage equipment to life 
by doing nothing more than that.


A second problem with using pliers to scrunch a PL-259 is the risk of 
permanently deforming the barrel making future removal difficult if not 
impossible.


Plier-tightening has its place, but hardly more than the degree or two 
to which you alluded.


Take care of that dandruff!

73,

Kent  K9ZTV



On 7/16/2020 12:46 PM, Mike Harris via Elecraft wrote:
I must say that over many years and without any ill effect I've never 
bought into this idea of Gorilering up a PL259 with pliers beyond 
finger tight. A quarter of a turn is an unbelievable suggestion. I've 
just tried it and a couple of degrees is the best I could do without 
being brutal and even then I don't thing it would go any further.


Urban myth maybe?

Also, I've never had a failure after simply applying a generous wrap 
of self amalgamating tape, nothing else, to waterproof coax 
connectors. Our UV environment is pretty powerful, clear skies and 
sunshine can turn the skin on my head into huge dandruff seven days 
later after 30 minutes exposure.

Re: [Elecraft] Waterproof SO-239 covers

[Mike Harris via Elecraft]

I must say that over many years and without any ill effect I've never 
bought into this idea of Gorilering up a PL259 with pliers beyond finger 
tight. A quarter of a turn is an unbelievable suggestion. I've just 
tried it and a couple of degrees is the best I could do without being 
brutal and even then I don't thing it would go any further.


Urban myth maybe?

Also, I've never had a failure after simply applying a generous wrap of 
self amalgamating tape, nothing else, to waterproof coax connectors. Our 
UV environment is pretty powerful, clear skies and sunshine can turn the 
skin on my head into huge dandruff seven days later after 30 minutes 
exposure.

Don't forget to tighten the connector 1/4 turn after "finger tight" with
a pair of pliers to make a real seal.

Re: [Elecraft] K4 in production

[Fred Jensen]

Say again?  The virus began in Asia [Wuhan China to be exact] at the 
very end of 2019.  Many of the parts that Elecraft and every other 
manufacturer uses are sourced out of Asia.  Everyones' supply chains are 
disrupted now but slowly improving.


Elecraft is based in California.  The population density in California 
is high ... high enough that if everyone stood 1 meter from everyone 
else, some would be standing in Nevada and some in the Pacific Ocean. 
[:=)  From the news that leaks over the Sierra Nevada to Sparks, 
Elecraft is really working to both resume normal production AND protect 
their employees and families so they can continue normal production.

[Elecraft] FT8 - was "On Second Thought, I'll Take The Stairs"

[Paul Christensen]

>"And I have one that says "RTTY" but it's now a Digital DXCC.  I had to
resort to FT8 to work Monaco to get on the Digital Honor Roll, with the
other 330 having been on RTTY."

Just to quickly add my input before the topic is canned.

I'm not enamored with FT8 but just for grins, I conducted an FT8 experiment
a few months ago to see how many countries I could work with no antenna
terminated at the end of a broken open-feeder transmission line.  That's
right - no antenna, just a hunk of balanced open feeder line that sits
unterminated on my backyard fence.  Using a 100W rig with output power
turned down to 20W, SWR is off-scale.  I work on my own gear.  If I blow it
up, so be it.  

Over a few weeks I worked about 35 countries on 20m and 11 countries on 40m,
all FT8 of course.No antenna and sky high SWR.  By now, folks are
thinking."yeah no antenna, but your line is the antenna, balanced or not."
That's right.  There's just enough imbalance between the two conductor
feeders that the line has some radiation.  The imbalance is caused by the
usual culprits like proximity to aluminum gutters and some inherent
imbalance between the rig and feeder.  However, it just goes to show that
skill to make FT8 DX contacts rests largely with the algorithm.  Frankly,
most of the skill needed is in learning to install and configure the WSJT-X
software - which isn't difficult.  As such, I find it amusing that anyone
considers FT8 an accomplishment - and a semi-automatic one at that.  But for
those who feel it is an accomplishment, there's no point in denying their
satisfaction.

Paul  W9AC

most probably are, I am dependent on the auditory feedback to send CW properly.

I suspect I have a setting wrong.

Any advice would be much appreciated.

73,

Re: [Elecraft] Waterproof SO-239 covers

[Doug Daniels]

Thanks for all the responses and suggestions. I've decided to go with the
American Radio Supply covers, as they looked the best quality. I'll combine
them with some Scotch/3M/rescue tape/coax-seal, whatever I can source
locally. I would have gone with the PL-259 idea if I'd had any used ones
around.

Re: [Elecraft] KPA1500 in the IARU Contest Last weekend

[Walter Underwood]

There is some sort of popular folk theorem that open wire feed line doesn’t 
carry common mode currents. It is obviously wrong. Both wires high, both wires 
low, and that is common mode. Any RF that excites both dipole elements high 
against ground will cause common mode currents on the feed line. “Balance” does 
not fix that.

[Elecraft] OT: CQ VHF Contest this weekend

[Edward R Cole]

Although not about Elecraft products:

I though there may be some 6m ops on the list looking to work Alaska (KL7).

I will be on with 3-element yagi pointed to West Coast of US running 
80w on 50.313 (900-Hz) FT8.  I will be using "Contest Mode" which 
exchanges four-digit grid squares instead of signal 
report.  https://www.cqww-vhf.com/


Normally run even (first) sequence to work West Coast that normally 
are on odd (second) sequence.  But either sequence OK as I will adapt.


Opening last Sunday netted several stations in Pac NW for me.  But I 
have seen CO, NM, TX, and AL

Re: [Elecraft] Calibrating RX on the K144XV

[Keith Trinity WE6R]

After it is at a stable temp, just change the offset number so it is on 
frequency.

Do this below and above 146.000Mhz as there are two sections in the unit.

Easiest way is to inject an exact 146. signal, set the radio to 
fine, IE 46.0  go into offset menu and tap SPOT.

Then click down to 45.99 on the radio and do the other side.
Switch back and forth with the VFO, the tone should stay very close. Set 
the offsets accordingly if needed.


If there is too much drift, then order the OPTIONAL K144XV Reflock board 
(installs inside the K144) and will lock it to the K3's main oscillator, 
which is more stable.

They pulled the RefLock from the website but we did do another small run.
We have 7 in stock currently.

Sometimes the vendor refuses to send to a post office box.  What works
then, at least in the USA, is to specify the street address plus the PO
Box as if it was an apartment number.  I always get a laugh when UPS
refuses to accept the PO Box as a delivery address, but their Big Brown
Truck pulls up to the PO loading dock anyway.

This, of course, does not apply to items that the Postal Service will
not handle, such as batteries and corrosive liquids.

Don't forget to tighten the connector 1/4 turn after "finger tight" with
a pair of pliers to make a real seal.

Re: [Elecraft] K4 in production

[Joe DeVincentis]

Eric did a Zoom meeting with the East Coast Ham Operators (ECHO) group on 7/14 
(Tuesday).

It was nice to see and hear some of the history of Elecraft.

The question of K4 production was asked.  He was very forthright.  They have 
adjusted their manufacturing process for employee safety.  Good to hear.

Eric said that the hold up right now is parts.  Unfortunately they can't 
control the big manufacturers.  It does sound like production will be soon.  
Personally, I can't wait.  The more I hear about the radio, the more excited I 
get.  I feel like a kid waiting for Christmas to get here.

IIRC, ECHO plans to post the video on their youtube channel soon 
(https://www.youtube.com/channel/UCP-gkJVxKm1iS43RwYsaKuA

[Elecraft] K4 in production

What I want to see on this list is when the K4 goes into production.
Everything else is immaterial. That is what I am looking for. The Eureka
announcement.

I can not tell you how many things, parts, drugs, cars, boats,planes,
lumber,steel, food, travel are impacted by the pandemic that this is little
stuff and the K3 still soldiers on waiting for it's retirement, hopefully
sooner than later.

Re: [Elecraft] Waterproof SO-239 covers

[Dave Cole]

By the way...  These caps also fit the mic connector on the front of the 
K3...


I use them extensively on all outdoor SO-239s, and one on the mic cover 
for the K3. :)


If you sign up for the mail list at American Radio Supply, they will 
send you a coupon for 10 bucks off a 25 buck order fairly routinely...


They are good folks, care about customer support, and in general provide 
a very good product for a good price.


I also use their PL-259s, and adapters for 8x, and they take solder, and 
hold up well...

[Elecraft] CWT Calibration

[Wilson Lamb]

I have deduced that the bars in the CWT display are 25 Hz apart.
Does anyone know if that's right?

Re: [Elecraft] Waterproof SO-239 covers

[Vic Rosenthal]

This is frustrating for those of us who don’t live in the US or Europe. Even 
before Corona I tried to order some hardware from McMaster-Carr in the US, only 
to be (somewhat unpleasantly) turned down. The same from other suppliers.
I don’t know what’s the big deal when we pay the postage. I used to send 
packages around the world when I was in the US, and there was only one simple 
customs form to fill out.

A great selection of bits. Unfortunately when I tried to order a couple 
of microphone connector dust caps for my K2 and K3. The system took the 
order but they refused to post them.

Re: [Elecraft] KPA1500 in the IARU Contest Last weekend

[CUTTER DAVID via Elecraft]

Jim
We're drifting off topic and you're pushing at an open door. 

I accept that wire size has an influence, but in my experience on smaller cores 
(UK limit is 400W) wound with RG316 I have observed the core getting hotter 
than the wire.  

BOK = Brick On Key.  I think it was Alpha that used this in their advertising.

So, in the protagonist's system, if he finds his swr climbing for no apparent 
reason, rather than blaming the linear it might simply be the core of the choke 
getting too hot with continuous use.  A bigger core (or doubling up) helped me 
and it might help him.
