[Elecraft] Elecraft CW Net Announcement

2017-05-20 Thread kev...@coho.net 

Good Evening,

Spring, with a few sunny days, has brought flowers, birds, and the 
biting flies.  This year's crop of no-see-ums is vicious. I get about 
thirty seconds outside before they start burrowing into the corners of 
my eyes.  Uck!  Anyone from Alaska or Canada know any remedies?


   HF has not been very productive recently.  But today there was a 6 
meter opening which worked its way from East Coast to West Coast.  I 
would copy a call sign and then they would disappear.  But then there 
was the next one to chase.  The QSB sounds different on that band if 
that is possible.


Please join us tomorrow on:

   14050 kHz at 2200z Sunday (3 PM PDT Sunday)
7045 kHz at z Monday (5 PM PDT Sunday)

73,
Kevin. KD5ONS

I've done a lot of modeling using NEC, and every antenna I've built has 
performed as the calculations predicted -- unless I screwed up the 
model. Likewise, in my professional life, I did a lot of careful 
modeling of sound systems I designed, and when I got the model right and 
built what I modeled, the system worked as predicted.


Brown's first law -- "if you think there's a difference between theory 
and practice, you don't know enough about one or the other." In other 
words, there were variables that you didn't consider or know about, like 
terrain, ground conductivity, mounting height, propagation, loss in 
matching or coupling methods, loss in traps, etc.

Re: [Elecraft] Beam antenna question

2017-05-20 Thread Vic Rosenthal 
The TH11DXX that G3TXQ compares to the Hexbeam has at least 3 elements on each 
band and is a modern design, no traps. If someone found that the C3 (2 el on 
each band) outperformed it, I would be very suspicious that something was wrong 
with the sample tested.
I did look at the wrong picture and you are correct that the XR5 is 9 elements.

comes with a capacity loaded 20m element Option (XR6-TC which reduces 
the longest element from 11.6m to 8.9m) and reduced turning radius too!"
It just clever marketing. The first 2 pictures on that page are

Re: [Elecraft] Beam antenna question

2017-05-20 Thread Igor Sokolov 

Joe,

Reality sometimes differ from calculations.

XR5T has shortened 20m elements and pretty poor F/B as compared to Hex. 
Last year we were operating in WPX contest from Madeira, CT9 and had 2 
antennas up on 15m band. One was 4 el Op-Des 15m full size monobander 
from Innovantennas. Another one was Hex. Both installed at the same 
height of 10m above the ground. We were surprised to find out that Hex 
had been always outperforming 4el Innov into Eu and the USA. so we ended 
up using only Hex.


Besides XR5 is 3 times heavier them Hex and much more visible (let it's 
price alone).


BTW is somebody wants a pair of these 4el 15m full size monoband 
Innovantennas, they are for sale, stored in Madeira, and we are selling 
them for 50% of their original price.


Fiberglass spreaders of our Hex are coming from Maxgain and UV 
resistant. So are wires and ropes. All bolts and nuts are made of 
stainless steel.

Your concerns are well placed with antennas made of fiberglass and
dacron/kevlar cords.

Instead of a hexbeam, I would recommend looking at the Innovantennas
XR5T: 
, 


or the JK Antennas Navassa 5:


Both have boom lengths of 12 feet or less, cover 20 - 10 meters and
have optional 6 meter add-ons.  Either should significantly out
perform the hex beams and - since they are aluminum antennas that do
not use UV sensitive fiberglass, kevlar and dacron components - should
significantly outlast the hexbeam with significantly less maintenance.

I really appreciate all the comments.  I do have a follow up
question:

An aluminum beam can be left up for years. I was reading one review
of a particular hex beam and the poster said that after 4 years,  the
cords holding the beam together had become brittle and started to
fail from UV exposure and the main support members had deteriorated
for same reason.

These beams are not cheap,  I don't want to be taking the beam down
and replacing main structural components every 5 yrs.

Can anyone with a hex beam comment on this?

Hello,

Have you always wanted an Elecraft? A KX1, K1, K2,  whatever? 
I’ll build any of them.

Does your K2 need a tuneup?

In addition to tuning your rig, I can also rescue a building project you might 
have started some time ago.

See what my clients have said about my construction and service work at 
http://www.eham.net/reviews/detail/6768

Re: [Elecraft] KX3 not responding

2017-05-20 Thread Rick WA6NHC 
In some cases, a complete power off, power supply disconnected (desktop, 
battery pulled for laptop) is needed.  Sometimes components 'stick' and 
the only way to clear them is a complete cold hard reboot.


It's also not just USB dongles, sometimes the same thing happens on real 
serial ports.

Use that COM port number in KX3 Utility and it should recognize the KX3.

> Why do you think it will "significantly outperform the hex beams?"

Based on the performance data (K7LXC/N0AX) for the original Force 12
C3 and TH11 with comparisons of the broadband Hexbeam and the TH11.
The K7LXC/N0AX field data shows the C3 outperforming the TH11 while
G3TXQ's web page 
shows the TH11 with approximately 3 dB advantage over the broadband
hexbeam.


I wouldn't say an 11 element yagi with capacity hats on the elements

Neither the XR5 nor the Navassa 5 has 11 elements *or* capacity hats.
The XR5 is a 9-element antenna and the Navassa 5 has 10 elements as

Your concerns are well placed with antennas made of fiberglass and

Instead of a hexbeam, I would recommend looking at the Innovantennas

or the JK Antennas Navassa 5:


Both have boom lengths of 12 feet or less, cover 20 - 10 meters and
have optional 6 meter add-ons.  Either should significantly out

this stuff:

It has survived nicely holding up a wire antenna for ten years so far in
high winds, sunshine, rain, snow, and freezing weather. It's hard to imagine
that a Hex beam would put more strain on it. 

However, I am in Oregon. The rope is advertised as UV resistant but we don't
get nearly as much UV as some other areas. (Sunblock salesmen go broke

Re: [Elecraft] Beam antenna question

2017-05-20 Thread Vic Rosenthal 
Why do you think it will "significantly outperform the hex beams?" 
The point about uv is well taken re fiberglass, but I don't know what the cords 
on all the hexbeam versions are made of. There are uv resistant materials 
available.
I wouldn't say an 11 element yagi with capacity hats on the elements has an 
especially low visual profile!

I have had several homebrew hexbeams, which have survived weather quite well.

1. Use UV-resistant cord, e.g. 3/32" "Antenna Rope" double braided polyester.

2. Paint the fiberglass spreaders, 2 coats, e.g. black "Fusion" spray
paint, recommended for plastic lawn furniture.

3. Use a coaxial center post, i.e. aluminum rod inside aluminum tube,
so that only the stainless steel screw heads are exposed to weather.

4. Use a 90-degree fitting to attach the feedline, so that it can hang
straight down, alongside the center post.

Re: [Elecraft] Beam antenna question

2017-05-20 Thread Ron D'Eau Claire 
Any horizontally-polarized antenna needs to be at least 1/2 wavelength above
ground for optimum performance, e.g. 32 feet up on 20 meters, 16 feet up on
10 meters. 

They will work at lower heights of course, but at reduced gain as they are
lower. 

20 feet sounds like a reasonable compromise for a 14 MHz and up antenna,
especially since the actual apparent ground is usually somewhat below the
surface of the earth in most locations.

73, Ron AC7AC  

-Original Message-

I have also read they only need to be up about 20 feet high.

Re: [Elecraft] Beam antenna question

2017-05-20 Thread Phil Hystad 
I have a Traffie Hexbeam (Traffie retired and the company is no longer in 
business) and it has been up for about 12 years.  My last check of the 
elements, coaxial connection and so on showed no problems what-so-ever.  
Operating performance seems to be just as good today as when it first went up 
in 2005.  Weather has been rain (mostly), sun with high temperatures reaching 
into the 90s usually in August (one recorded day at 103 though), and snow once 
or twice a year but the snow never lasts for more than a day or two at most on 
the antenna.

I am not sure about other vendor’s versions of the Hexbeam but mine has been a 
worthy contender in the battle with weather.

By the way, the Hexbeam is visible from the Google satellite photos of my house.

Your concerns are well placed with antennas made of fiberglass and
dacron/kevlar cords.

Instead of a hexbeam, I would recommend looking at the Innovantennas
XR5T: 
, 


or the JK Antennas Navassa 5:


Both have boom lengths of 12 feet or less, cover 20 - 10 meters and
have optional 6 meter add-ons.  Either should significantly out
perform the hex beams and - since they are aluminum antennas that do
not use UV sensitive fiberglass, kevlar and dacron components - should
significantly outlast the hexbeam with significantly less maintenance.

easy to put together and pretty light.  I compared the Hex beam to a 2

I have that kind of neighbor hood, so I painted the spreaders grey, and the 
mast and cables grey, to match the garage and  the too  frequent midwestern 
sky, put  the mast base and rotor inside the garage,  so the hex just kinds 
blooms about 10 foot over the roof.  

With the rotor and base hidden, most people don't notice unless I point it out.

Good luck, Scott ka9p

Re: [Elecraft] Beam antenna question

2017-05-20 Thread Igor Sokolov 

Terry,

As many others mentioned? Hex beam is the best choise. I have 3 of them 
made by EU manufacturers (very good quality). And one of them 
(www.foldinganteannas.com) is even foldable and very light weight.


You may also look for MW0JZE Hex. he also makes light version. Do not 
mess with Al antennas. Hex Beam is much better and easier for portable 
operation.

The hexbeam will have gain on WARC bands as well as 10-15-20. My 
experience is that with conditions as they are today, 17m is VERY 
important (so is 30, for that matter) for DXing.


I have a rotatable dipole and yes, it definitely does help a lot to 
rotate it! But it isn't a beam.
