[Elecraft] Elecraft CW Net Announcement

2020-08-29 Thread kevinr

Good Evening,

   It has been dropping into the 40s each night this week.  I almost 
started a fire in the woodstove. But, by noon it was back to 70 again.  
I collected a lot of dry, bucked up wood and got my exercise.  Ten more 
truck loads and I'll be started.  While I was complaining to the jays I 
must have used my hands too actively.  I saw three sets of ears flick in 
my direction.  About a hundred yards away, through the thinned fir 
trees, I saw a doe, then a yearling, followed by this year's fawn.  They 
weren't moving too fast but they were looking at me.  So were the jays.


   I reviewed a few of my college texts this week: "Fundamentals of 
Applied Electromagnetics" by F. T. Ulaby and "Antenna Theory - Analysis 
and Design" by C. Balanis.  All my book marks and penciled in notes sped 
things up a bit.  Now I need to spruce up the code I wrote around three 
of the antennas I modeled.  My code gave me radiation patterns for 
training neural nets for 1/2 wave dipoles, 1/4 wave monopoles, and full 
wave loop antennas.  It will be fun to add transparency and shading 
while I map them as 3D objects in space.  I need to revamp the sliders 
controlling height above ground and orientation.  They were a kluge when 
I created them, but worked well enough to create data sets to train my 
adaptive ARTmap neural nets.  Ulaby's book is a great primer on fields 
and waves.  Chapter 9 introduces antenna analysis for a 1/2 wave dipole.



Please join us on (or near):

14050 kHz at 2200z Sunday (3 PM PDT Sunday)
 7047 kHz at 0045z Monday (5:45 PM PDT Sunday)

   73,

Re: [Elecraft] KX3 microphone nut size

2020-08-29 Thread Nr4c
There were several answers, many were just wrong (1/4-20. Or likely). 

But the absolute best answer was from Wayne of Elecraft who is sending out an 
envelope with a nut.  So who cares what size it is?

I think it might be 6X.75 (mm).

Not to forget winning WW1 and WWII.

I remember punch cards fondly.  At Hughes I took a company-sponsored Fortran IV 
course.  I was in Tucson and the main-frame was in CA.  We would do our coding, 
punch and submit our cards, the batch would be run overnight and we would come 
in the next morning to find out how many typos we made.  I wound up dating one 
of the key punch girls, and reduced my typos to zero.

And Len, there is a real society for exactly what you point out ... The 
Duodecimal Society of America [www.dozenal.org] that promotes changing 
the base of our number system to twelve for exactly the same reason.  
Not quite the same as the Flat Earth Society, but equally unlikely to 
make much headway.

The Metric Conversion Act goes back to the Ford administration in 1974
(*).  It is enforced slightly less than the Uniform Spitting on the
Sidewalk Act that predates it.  The main reason that we see it at all in
the US is than manufacturers dealing in world-wide markets do not want
to have two different production lines,

* My Ford sedan is built to metric standards...  :)

During my tenure, FCC rules and standards were rewritten to express
dimensions in metric, but the conversion from USCU wasn't smooth.  For
instance, one specification for certain antenna heights was "20 feet
above ground".  So what did the FCC do?  Changed it to "6.1 meters (20
feet) above ground".  Why not an even 6 meters??  Everyone still refers
to it as the "20 foot rule".

The neglected metric unit, although not past of the SI, is the gradian
(grad).  100 grads to a quadrant.  400 grads to a full circle. 1 grad =
0.9 degree.  It is used mainly in European surveying, but since May 2020
is legal for use in the US.

Nope, that red line should move off to the right on the P3, just like it does

[Elecraft] K3/P3: What Have I Done??

2020-08-29 Thread James Bennett via Elecraft
Just spent an hour reviewing the K3 and P3 manuals to no avail. I’ve had these 
two pieces of equipment for ten years and you’d think I ought to know exactly 
how to control them, but it appears that either something inside has gone 
kaflooy or I’ve screwed up something myself. I suspect the latter…

When I turn on RIT and adjust the RIT knob, the K3 changes frequency and 
displays it correctly on the LCD. However, what happens on the P3 is the 
opposite! Turning the RIT knob clockwise increases the K3 frequency and 
display, but the red line on the P3 moves to the LEFT, not the right as it 
should. The P3 frequency display increases as it should, but the red line goes 
the opposite direction. The XIT function works as it should.

Any hints? This has me stumped!

Re: [Elecraft] W2 wattmeter

2020-08-29 Thread Don Wilhelm

Joe,

The telling answer is in your statement "the radio has an internal ATU".
The radio is showing the SWR between the radio and the ATU.
The wattmeter is showing you the SWR after the ATU - in other words, the 
SWR of the untuned antenna.  So there may be nothing wrong.


Connect a dummy load to the wattmeter output and see what that reads - 
should be 1.0.

10m-80m OCFD that will be transferred from 25' pipe to 40' tower.

Re: [Elecraft] KX3 microphone nut size

2020-08-29 Thread Steve Gray
This is supposed to be addressed to the group, not Rich specifically, but on
this so-called "smart" 'phone, I cannot see how to do that, nor how to strip
out the miles (kilometres!) of duplicated commentary. Mea culpa my friends.
One day!

While I was still working, I used to build aircraft interior equipment,
specifically galleys and associated structures, and everything was in
imperial (actually decimal inches.) We used UNF and UNC attachment
fasteners. Even Airbus tolerated our decimal inch drawings and Boeing was a
given. I became completely conversant with imperial- both fractional and
decimal, but also metric. I routinely read fractional tape measures as a
decimal inch converted mentally on the fly. What I'm saying is it's only a
cocktail of laziness, stubborness and * to plough ahead with one
system completely in denial of another potentially better one. In my closing
years I did Q.A. and First Article Inspection. I wouldn't have survived with
Boeing or Airbus if I'd refused to be conversant in all systems.

While at college (I did Environmental Engineering) we were taught
dimensional analysis of equations. Everything is reduced to Length, Mass and
Time (ignoring wild cards like viscosity). When you see an equation
substantiated in this way, a light goes on in your head and the benefits of
the S.I. System are obvious. Until that is inculcated into your skull, you
take equations as something that is commited to memory but maybe never
stopping to consider why or who the heck figured that out? Sure you can
arrive at the same results using imperial units, but only if you remember
(without fail) to deploy empirical fudge factors so inches can be used
alongside ounces and so on.

That said, the S.I. unit is the metre. The recognised sub unit is the
millimetre. (not the centimetre). Suppose you want to cut something six feet
long (1,829 millimetres)? You pull out the tape measure and it happens to be
upside down. Enough times for it to be a lurking threat you measure (eg)
1,819 instead of 1.829 by mistake. It's your own fault, but for humans
interacting with the world I submit that feet and inches are a better way,
but for engineers (or anyone that likes to think of themselves as such.) The
S.I. System is a far better way to do things. I also think that the evolved
usage of centimetres is a tacit admission that inches were better than
millimetres. $0.02 of course.

Steve, G4VRR.

[Elecraft] KX3_2m_limited_power

2020-08-29 Thread HB9MFL
Hi all,

I have the following effect on my KX3 equipped with the 2m module:
Max Power is set to 3.0W
If I set to TUNE I can increase the rf from 0 up to eg. 3.0W.
But the power does only increase to about 650mW and the most confusing is
the fact that in the display the power jumps back to 0.9W!
A short movie can be see here:

https://www.mycloud.ch/l/P00BBFDF3256A56FD3D07AB35274144A50BF5F24AB9A6B837983B214C77EE5ADA

Unmount all to check. The nut was no more soldered to the final transistor.
Reload firmware
Reload the last configuration when the TRX was working well.
>> Still the same confusing effect.

Re: [Elecraft] KX3 microphone nut size

2020-08-29 Thread Rich NE1EE
I enjoy cooking and baking. All my recipes are in metric, and based on mass 
where ever I can, to get away from "cups", etc.
I am an amateur woodworker, and all my work is metric. A while back I completed 
a table with nearly 100 unique angles (trust me, it looks fine ;-)...all the 
while being told that a) I couldn't do it at all, and b) if I could, not in 
metric!!!
I had a guy at the place where I buy wood remark that wood was coming in 
"weird" dimensions! When I got home, I measured it and found that it was exact 
metric dimensions.
Mixing shellac is way easier in metric. You should see the hoops that you jump 
through using USCU.
My ham buddies are constantly remarking "oh, yeah, you use that metric stuff" 
when I mention that my antenna is a 40m EF. Doesn't that make more sense when I 
think of the bands it might work on?

***It's just a difficulty making the transition...then it's easier. I'll bet 
you could get everyone in the US to criticise the use of pounds, shilling, 
pence, and so on, when compared to the dollar in base 10...but turn the 
discussion to a general one of metric, and I get "but it's so confusing" all 
the time...is it really easier to remember conversions of feet and inches to 
metric for antennas? I was calculating an antenna dimension the other day, and 
it came to 1780mm...which is 1.78m...no fancy math involved. Imagine me 
calculating that in feet, and then converting to some precise measurement...I 
don't have a tape measure marked in decimal feet.

I bought a 30m tape that winds up into a case. It has been working fine for 
many years.

With regard to "12 has more factors than 10" in another post, I suggest that 
this is a matter of habit. Being able to divide 12 so many ways doesn't 
necessarily make it more useful, I opine, just more familiar. In grammar 
school, I had to learn a bunch of yard-foot-mile-etc conversions, but in SI, 
it's all base ten. I can divide 1780mm any way I want. In fact, a friend of 
mine who is a builder came to me for help one day calculating distances to do 
with an unusual roof angle. Showing him how to use his calculator to do the 
calcs was the easy part...the hard part was translating 20 feet 3 3/16 inches 
to decimal so that he could do the math, then convert that back to feet and 
inches. There are, I hear, calculators specifically designed to do this sort of 
math. Talk about a niche product.

I too a piece of heavy glass (amateur photographer equipment) to a glass place 
to be split in 2. You should have seen the effort to measure in USCU and divide 
accurately by 2, without decimals. A snap in metric.

0C as a freezing point makes so much more sense than 32F. And yes all my house 
temperatures report in C. And I use ISO dates -mm-dd, and 24hr time. Can't 
tell you the number of times there was confusion because someone was not sure 
if a time for some event  was 8am or pm, when the context could go either way.

***I don't say that converting our brains is easy, especially when we have 
learned something so fundamental as distance and volume in our youth...drilled 
into us, as it were. But the effort is so well worth it. I completely empathize 
with those who are still USCU, and find it a struggle to move to metric. The 
hardest unit for me is big distances. I still feel more comfortable estimating 
some distance as 3 miles than as 5km. Even that would be easier if the country 
just bit the bullet and set a time limit on moving to metric. Then we'd all be 
on the same page.

There are some illusions. Say I know that I need to go 15 miles, and I can do 
it at 60 mph. Neat, right? But what if I need to go 13 miles at 45 mph? (OK, 
those of us who do math estimating easily in our heads find this trivial.) But 
we fall into the habit of creating such shortcuts. I am much more likely to 
estimate a 13 or 14 mile trip as 15, so the math is easier. And 60 mph is a 
mile/minute, also convenient. But I could as easily get used to doing 100kph, 
and then saying that 50k will take 30 minutes. Driving around metric countries, 
it doesn't take long to see that all the speeds are in metric-friendly units, 
not something like 96.6 kph.

I do a lot of my own work, such as maintaining my motorcycles and such...so I 
have 2 sets of tools. Sigh. there was a time when I could get metric items more 
easily at HD, but several years ago they switched to carrying far fewer metric 
items.
