ARISS-International Meeting Attendees:
The ARISS-US team had a meeting with NASA yesterday on the November ARISS-I
meeting and our tour plans. We were informed that our ARISS tour time,
originally planned for Monday November 14th in the afternoon, will change.
We are now scheduled from 8:30 am-11:30 am on Monday November 14.
NASA stated that they are overwhelmed by the substantial influx of tour
requests on Monday. This includes the SpaceCom conference, the ARISS-I
meeting and the normal tour groups from Space Center Houston. An estimated
2,000 attendees will be coming to the SpaceCom conference (industry,
academia, and government space leaders) that will be held the same time as
our ARISS-I meeting in Houston. Unfortunately, this will limit tour guides
and tour availability in the times they can work with our group-thus the
need for the tour time change.
We apologize for this, but I think you can understand this is unavoidable.
If you have any questions or concerns regarding this, please contact me
directly at my ka3hdo@xxxxx.xxx <mailto:ka3hdo@xxxxx.xxx> e-mail.

Please look for K2BSA/5 running satellite operations for Jamboree on the Air
this Saturday from the National Scouting Museum in Irving Texas in EM12.
Andrew Koenig, KE5GDB and Keith Pugh, W5IU will be running the sat. station
this year from about 1500-2200Z on the 15th. We even have the educational
model of the Fox satellites to show off to the Scouts. Please give us a
shout and be patient if a Scout happens to be on mic. Your interest in
contacting us might just spur a prospective new ham or two to take up our
challenging aspect of the hobby.

Good morning
Postponed to this weekend due to Hurricane Matthew, we will be operating
SATCOMs and HF at the Chesapeake heritage and Waterway Festival in
Chesapeake, VA. Operations will start as early as 0900 - 1600 EDT.
We are a small group mentoring youth in electronics and wireless
communications and sponsor to school amateur radio clubs in Chesapeake -
W4FOS and W4GBH.
Caution: If we do not have enough people to show up we could miss a pass if
we are busy speaking with parents and students.
K4AMG outfits the schools with complete HF stations, and 2 meter equipment.
Our Portable SATCOM Station is computerized dialed into a TS 2000, Yeasu AZL
rotors, Preamps, and M2 Beams.
We sponsor a STEM TREASURE HUNT where the winning class wins a price.
The students travels from vendor to vendor collecting answers to about
10 -15 questions they are giving. The class with the most correct answers
wins.
K4AMG is a public charity 501c3.
Maybe we will hear you on the linier birds.

Larry,
Thanks for asking. Unfortunately you are correct regarding the Monday tour.
That is why we wanted to get this on -bb, so all are aware of this unfolding
issue.
Once we learned about the tour time change, we were acutely aware that it
conflictrf with the cruise arrival time. We pushed back on NASA fairly hard
to correct this but were unsuccessful. Their only suggestion was cutting
back the tour to only an hour---from 10:30-11:30--to accommodate those on
the cruise. We did not think this was a good idea because the tour would be
inferior and it is not clear that those on the cruise could get there by
10:30. So we are working alternatives for those affected.
If folks are affected by this, we need to generate a list of all that want
to attend the tour but cannot due to this constraint. Once we have that, we
plan to go back to NASA and see what alternatives we can offer up to them.
FYI we have already engaged with NASA on alternatives. I am not sure what
they will be able to support yet. So, please, if you are affected by this
new tour time constraint, let me know ASAP at my ka3hdo@xxxxx.xxx
<mailto:ka3hdo@xxxxx.xxx> address that you are still interested in the tour
be cannot come due to the tour time change.
Larry, I have you on the list.

telemetry as part of a lesson in a classroom. Any grade level (k -
undergraduate college) is fine.

Content-Type: text/plain; charset=US-ASCII
My head filled up with questions today, so I'm trying to get a few out
to the folks who know the answers.
First, Thanks to Jan for sending a copy of his presentation!
My question: We can get data about voltages coming from X, Y, and Z
solar panels. I understand that X, Y, and Z are three spatial axes.
But solar panels are planes. Are the panels oriented in a particular
plane (i.e. is the X panel in the X-Y plane or the X-Z plane) or do they
rotate around their particular axis?
If they are fixed in one plane, is it standard for most satellites, or
does it vary from satellite to satellite? If it varies, how can we tell
which plane the solar panel is in?
Are the axes always in the same orientation (e.g. is the Z axis always
pointed towards the Earth?)?
If there is a book or other reference for these kinds of things, please
let me know.
Thanks for your thoughts!!

Hello All, I am wondering if there is any "simple" conversion factor to use
to modify the length of an antenna element from insulated #10 AWG copper
wire to anther gage of wire or to aluminum or copper tubing.? I don't wish
to learn any modeling software at this time?? I need the information so I
can use materials I have on hand to build yagi antennas for 2 meters and 70
centimeters.

The best I can do for you comes from the documentation for antenna modeling
software which does cover the impact of the element diameter. The impact
on the driven reflector is almost zero. The impact on the directors is not
quite zero.
Doubling the diameter of the element, example going from 12.5mm to 25mm
(1/2" to 1") will cause the driven element to SHORTEN by 5mm (that's about
0.2 inches). In other words, you can pretty much forget it. The impact on
the directors is larger, SHORTENING it about 25mm, or an inch. But even
so, these dimensional changes are FAR less significant that the changes due
to height, ground characteristics, and what else is near the antenna. In
other words you can forget about factoring it in.
Same thing is pretty much true for insulated vs. non-insulated wire -- you
can pretty much forget about it.
Good luck!

Hi James,
I think you may be out of luck. AFAIK, there isn't a simple conversion
since the entire dimensions of the antenna is dependent upon the diameter
of the various elements, that is the primary reason people use the modeling
software in the first place to find these things out! Changing the
diameter of the elements will affect their length as well as the spacing
between the elements - there's nothing simple about any of it!!!

Bob, you're going to get a wide variety of answers to your question and for
good reason. All insulation is not created equal and therefore will have
varying effects on your project. I'm not aware of a simple formula either
but could possibly assist in your efforts. It sounds like you want to use
10awg Romex. In this case, I'd strip the insulation from the copper, secure
one end of the copper in a vice or similar device, put the far end in a
variable speed drill and gently twist the copper wire to create stiffer
material. What yagi design do you have in mind? How many elements? What
type of feed? How high do you intend to mount the antenna? These things all
need to be taken into consideration for efficiency.

Hi all,
I just noticed today that recently the Outernet satellite information
service just switched from K-band to L-band.
This allows for a much smaller patch antenna to receive the signal from
Inmarsat, but at a lower bit rate (20 MB/day).
This is a free service, and can be received with low-cost hardware:
Raspberry Pi 3, RTL-SDR, LNA, and patch antenna. All available from
Amazon.
Apparently APRS is being rebroadcast, as well as weather satellite
information.
