MEDIA ADVISORY: M13-103

JULY SPACE STATION SPACEWALKS TO BE PREVIEWED AND BROADCAST ON NASA TV

WASHINGTON -- Two Expedition 36 astronauts will venture outside the
International Space Station twice in July on spacewalks to prepare
for a new Russian module and perform additional installations on the
station's backbone.

NASA's Johnson Space Center in Houston will host a NASA Television
briefing to preview the spacewalks at 2 p.m. EDT Tuesday, July 2.
Reporters may attend the briefing at Johnson and other participating
NASA centers, or ask questions by calling Johnson's newsroom at
281-483-5111 no later than 1:45 p.m. Tuesday.

Briefers will include:

-- David Korth, NASA spacewalk flight director
-- Ernest Bell, Spacewalk 22 spacewalk officer
-- Karina Eversley, Spacewalk 23 spacewalk officer

Flight Engineers Chris Cassidy of NASA and Luca Parmitano of the
European Space Agency will conduct the spacewalks July 9 and July 16
from the station's Quest airlock. Each spacewalk is scheduled to last
6 1/2 hours. Cassidy and Parmitano will replace a space-to-ground
communications receiver and wireless video equipment and install
power and cables for a Russian multipurpose laboratory module that
will be launched later this year. The new module will serve as a
research facility, docking port and airlock for future Russian
spacewalks and will replace the Pirs module.

Cassidy, who is designated EV1 for the spacewalks, will wear a U.S.
extravehicular mobility suit bearing red stripes. The spacewalks will
be the fifth and sixth of Cassidy's career. Parmitano, who is
designated EV2, will wear a spacesuit with no stripes and will be
making the first two spacewalks of his career. He will become the
first Italian astronaut to walk in space. Both spacewalkers will wear
helmet cameras to provide up close views of their work.

NASA TV coverage of the spacewalks will begin at 7 a.m. on both July 9
and July 16. Both spacewalks are scheduled to begin at 8:10 a.m.

Field Day 2013

K6LCS <clintbrad4d@...>
 

AMSAT Field Day 2013 - APRS 'Droid app - AO-7

Every year AMSAT promotes a satellite version of Field Day during
the ARRL annual operating event which is held on the 4^th weekend in
June. This year Field Day will take place from 1800 UTC on Saturday
June 22, 2013 through 2100 UTC on Sunday June 23, 2013.

SaudiSat-Oscar-50 will be the only operational FM transponder
satellite this year. If you are considering only FM voice operating
for your AMSAT Field Day focus the single uplink/downlink channel
will be extremely challenging. As in prior years, this intense
congestion on FM LEO satellites drives the limitation in the rules
allowing their use to one-QSO-per-FM-satellite. This includes the
International Space Station. You will be allowed one QSO if the ISS
is operating Voice. You will also be allowed one digital QSO with the
ISS or any other digital, non-store-and-forward, packet satellite (if
operational).

If you have worked the satellites on Field Day in recent years, you
may have noticed a lot of good contacts can be made on the linear
transponder satellites including VO-52, FO-29, and AO-7. During Field
Day the transponders come alive like 20 meters on a weekend. The
transponders on these satellites will support multiple simultaneous
SSB or CW contacts.

The AMSAT Field Day 2013 event is open to all Amateur Radio
operators. Amateurs are to use the exchange as specified in ARRL
rules for Field Day. The AMSAT competition is to encourage the use of
all amateur satellites, both analog and digital.

For the complete listing of the AMSAT Field Day Rules please refer
to the documents posted on-line at:

Thank you, guys. I am doing it correctly. I work SO-50 because it is the
only bird that I know how to work. I am thinking that my reception
problems are because of RFI near my QTH.
RFI can be a problem. For about 2 years, I couldn't work AO-27 from my balcony because of something that was putting out noise on almost the exact frequency of the bird's downlink. I eventually determined that the noise source might have been a cell phone repeater that had been put on the roof of a nearby high-rise apartment building in our complex.

Right now, I've got a problem with noise on 2 m SSB. I suspect it's the reason I'm having difficulties working the linear birds from my balcony this year. The noise source seems to be located in one of the neighbouring apartments.

I could move my station down to my car in parking stall because there's less noise from that source there. However, moving all my gear back and forth can be a bit of a chore.

I would like to learn the linear birds,
but with no Elmer, it becomes difficult. I have a Yaesu 857D and I guess
that I would need another 857 or a 2000 radio as a stand alone. Since I
want to work portable, with my Arrow antenna, I need something that I am able
to move around easily. Someone's web site states that they use two 857
radios. It is time that I branch out to other birds.

I do have a vertical 10-40 M. antenna at my QTH, but I do not know if that
would be of use in working linear birds. Any help or suggestions, would be
greatly appreciated.
Maybe you could use it for working AO-7 in Mode A just after it comes up over the horizon.

Brad:  Use the Arrow antenna like a pointer, point it toward where you think the Sat should be. Sometimes it helps to twist  your wrist and rotate the arrows in a circle  as the Sat may be tumbling some and it will make it clearer.  There are several vidio's on You tube that you can watch which may help.  I have never used a preamp with the Arrow Antenna and can hear them fine.

Always point the end of the boom towards the satellite so that both sets of elements are perpendicular to the signal path.

However, it will likely be necessary to rotate the antenna about the axis of the boom to allow for changes in the signal polarity. This can be a bit tricky at times, particularly during low-elevation passes.

A full-duplex radio is particularly useful for this.

Randy,
Thanks so much for the wonderful post.
We do so appreciate you and Eddy coming and sharing your expertise in working the birds.
I was hoping that I would have pictures posted by now, but lots to do this weekend after
the hamfest was over. I just got home from today's activates with helping with a graduation
and party. Sleeping seems to be optional... grin.
 
Any way, I am sure there will be much discussion about having another hamfest in our clubs
future. I am not sure we came out in the black on this one, but if you factor in my intangibles,
I do think our first one was a great success.
 
If nothing else, I did hear at least a couple of guys that now have the bug to learn and prepare
to work the birds in their future.  Cool Huh...

Eddy, KYØF and I returned from Adrian, Missouri this afternoon after having an excellent time at the Bates County Hamest in Adrian, Missouri where we were made to feel very welcome!  

We were there provide our Hams in Space Presentation on working FM Amateur Radio Satellites to a respectable size audience followed by a hands-on demonstration in the parking lot.  Three hams who have never worked satellites before tried their hand working a pass of SO-50, which came over the southern horizon in EM28 at about 12:11 PM-CDT.   Between the three of them, I believe they made seven or eight successful contacts!  (Thanks if you were at the other end of any of these QSOs!)

After all was said and done, we learned from Kevin Scrogham of the Bates County Amateur Radio Club, that their club is a very new organization, and that this was their very first attempt at a hamfest.  Well you could have fooled me!  Although small, this was a a very well organized event held in a great venue.  The class room we used for our the presentation was comfortable, well set up with tables, chairs, and a screen and projector.  It was the perfect size!  The hamfest itself was in a large area with ample space for tables and exhibits, while a concession was set up with all the staple foods expected at a morning hamfest.  (As you know, biscuits and gravy are to hams like doughnuts are to cops!)

Adrian, Missouri is about 45 miles, or just less than an hour's drive south of the Kansas City Metro Area.  Based on the time of the year, and their location, I expect the Bates County Hamfest has the potential to become one of THE prominent hamfests in the region!   

Keep up the good work, guys!  Our hats are off to you!

New Cubesats Showing Up in Newest Keplerian Elements Lists

JoAnne Maenpaa <k9jkm@...>
 

The AMSAT keplerian elements this week include many of the new cubesats. ESTCube-1, CUBEbug-1 are in the list. I could add them to my Nova tracking display with the usual methods after downloading the Thursday keps release (when the e-mail to the amsat keps list goes out then the new keps are also available for download). I'm sure space-track, celestrak, etc. already had them before the Thursday amsat update.

I use orbitron for tracking ... and that can control doppler (for my sdr
setup) and can also make predictions for next passes

No need to use internet then (only for updating keppler data)
