Hi Juan Carlos,
Good question. There are a few reasons I'm leaning towards the DK7ZB
designs. No doubt others will have differing opinions, and I'd be more
than happy to hear them.
* The G0KSC antennas are based on an aluminum boom, whereas the DK7ZB
PVC designs are based on a PVC boom (duh!). For a given design (e.g.
5-el 2m), the boom is also slightly longer in the G0KSC design. Those
factors mean more weight. I want to keep weight to an absolute minimum
to avoid having to deal with stronger cross-boom, stronger mast,
stronger rotator, etc.
* Related to the aluminum boom, G0KSC makes quite a fuss about the
importance of insulators, about the importance of the insulator
design, and about the materials used to make the insulators. He even
includes links to commercial insulators. Going with a PVC boom, this
is a non-issue, since there's no need to insulate the elements from
the boom.
* G0KSC provides a design that is built with 10mm diameter tubing.
DK7ZB provides measurements for several diameters, from 2.4mm to 8mm.
This gives me the option to use narrower (thus both lighter and
cheaper) material for the elements. If I build X-pols, that's twice as
many elements, so it matters.
* A while ago, I built an IOio antenna, so I'm quite familiar with
having to use a pipe bender to get the tubing bent correctly. It's not
easy (at least, it wasn't for me) to get the curves in exactly the
right places, trying to measure from the center of one curve to the
start of where to bend the next one. Also, with 3/16" tubing, which I
used for the IOio, it wasn't too big a deal to twist the tubing when I
didn't get two corners exactly parallel to each other. With the larger
tubing of the G0KSC design, though, that would be harder. (This is
evidenced by the fact that G0KSC even sells loop ends, noting that
"The most difficult part of building an LFA Yagi is bending the Loop
Ends and getting them right!".
So, in short, the DK7ZB designs seem, to me, simpler to build,
possibly less error-prone, and will give me very lightweight options,
even if I build X-pols.
Martin.

I didn't write it directly, but I assumed from the description you would
read that I indeed run full duplex (and to add to this: my system is
Linux, not Windows). If not Direwolf will wait for a free window to
throw out packets which will never happen because FS-3 is on all the
time. No, everything is working, except for the problem I described
before: all commands to the bird are heard and responded to, but
uploading a message will fail.
Desensing is also not the problem: got the appropriate filters in place
for that. Cheers,
Hans

Here?s to hoping that the ISS digipeater is turned-on sometime soon. I
missed getting to use it on a couple of passes today.

High School, Currie, TAS, Australia
Message-ID: <EF7A71A7974840A3B33A6BCF4A3E6377@???>
Content-Type: text/plain; charset="iso-8859-1"
An International Space Station school contact has been planned with
participants at King Island District High School, Currie, TAS, Australia on
19 June. The event is scheduled to begin at approximately 08:49 UTC. It is
recommended that you start listening approximately 10 minutes before this
time. The duration of the contact is approximately 9 minutes and 30 seconds.
The contact will be a telebridge between OR4ISS and IK1SLD. The contact
should be audible over Italy and adjacent areas. Interested parties are
invited to listen in on the 145.80 MHz downlink. The contact is expected to
be conducted in English.
King Island District High School is located in the Bass Strait off the North
West Coast of Tasmania. We cater for approximately 210 students from Kinder
to Year 10. Our school is at the heart of our community, we value each
student and their family. We have been striving to create resilient,
innovative lifelong learners; our school has been on a learning journey with
Literacy and Numeracy as our core fundamentals. Our students have the
opportunities for on-island and off-island camps from Year 3 and up, we
participate in sporting events in mainland Tasmania, we have students from
Kinder to Year 10 being able to access specialist Music and Art lessons. We
are grateful to have a well resourced MDT room, Computer Lab, kitchen which
has then eventuated into a school caf? 'The Rock Caf?', which offers caf?
style lunches, drinks and monthly dinners to our community giving our
students first-hand experience of hospitality. We are also in the process of
building our own golf hole to fit in w
ith the islands golfing influx of late.
Participants will ask as many of the following questions as time allows:
1. Why did you become an astronaut?
2. What training do you need to be an astronaut to go to space and
where did you do your training?
3. What sort of food do you eat and how do you determine your meal
times in space?
4. What do you do in your spare time so you don't get bored while in
space?
5. Does it get lonely in space?
6. How do you exercise in space?
7. How old is the International Space Station and do parts wear out in
space like they do on earth?
8. What is your job on the ISS and how do you do it?
9. What are space worms and why are they so important in space?
10. How long does it take to orbit the earth?
11. Have you researched the black hole and if so, how big is it?
12. What kind of research do you do?
13. Do you have any advice for any of our students wishing to follow in
your career path?

About ARISS
Amateur Radio on the International Space Station (ARISS) is a cooperative
venture of international amateur radio societies and the space agencies that
support the International Space Station (ISS). In the United States,
sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American
Radio Relay League (ARRL), the ISS National Lab and National Aeronautics and
Space Administration (NASA). The primary goal of ARISS is to promote
exploration of science, technology, engineering, and mathematics (STEM)
topics by organizing scheduled contacts via amateur radio between crew
members aboard the ISS and students in classrooms or public forms. Before
and during these radio contacts, students, educators, parents, and
communities learn about space, space technologies, and amateur radio. For
more information, see www.ariss.org.

Hi Hans,
I was able to upload a message (to you!) on FS-3 last night/this morning,
fully automated. So the satellite is evidently behaving OK.
Hope you get it figured out. Since I don't use Direwolf, sorry I can't give
any suggestions.

read that I indeed run full duplex (and to add to this: my system is Linux,
not Windows). If not Direwolf will wait for a free window to throw out
packets which will never happen because FS-3 is on all the time. No,
everything is working, except for the problem I described before: all
commands to the bird are heard and responded to, but uploading a message
will fail.
