An International Space Station school contact has been planned with
participants at BORG Monsbergergasse, Graz, Austria on 09 Nov. The event is
scheduled to begin at approximately 09:42 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
direct between OR4ISS and OE0ARISS. The contact should be audible Austria
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.
The BORG Monsbergergasse is a grammar school in Graz, Monsbergergasse 16.
Graz is the second largest city in Austria, located in the southeast of the
country. The school can easily be reached from everywhere in Graz using
public transport.
About 800 students attend the school and there are about 100 teachers. Our
students can choose between 5 different areas of interest: sports, science,
music, art and informatics. After four to five years the students graduate
from school after taking their A-levels.
The school offers a fantastic infrastructure for the students. Apart from
the classrooms there is a lab, a library and a cafeteria. There are special
computer rooms, four gyms and outside there are several courts for doing
sports. Besides there is a garden to relax in the breaks.
Participants will ask as many of the following questions as time allows
1. If the astronauts did not train on the ISS which consequences would they
have to face back on earth?
2. What measures are taken when an astronaut gets sick?
3. What kind of food are the astronauts allowed to eat?
4. What is your favourite food in space?
5. What is your daily routine on the ISS?
6. Do you wear special clothes on the ISS?
7. What do you do in your spare time?
8. People on water might suffer from seasickness. Is there a similar
sickness in space?
9. Can you describe your feelings and emotions when you see the earth from
above?
10. Do you think it will be possible for civilians to visit the space in the
near future?
11. Do you miss your family and friends?
12. Can you think of any moments when you wanted to leave the ISS and return
home?
13. What kind of research are you doing these days?
14. Which experiments do you consider the most interesting ones?
15. Do you also have fun on the ISS?
16. Have you ever noticed anything weird outside the ISS?
17. What are the risks of working in space? Does the ISS have an emergency
escape system?
18. What would happen if there was a fire on ISS?
19. Does it sometimes happen that you forget something on earth which you
would need in space?
20. Why do the times of overflight-forecasts sometimes change?

Bob,
If you are too high in the pass band / waterfall you can adjust the
center frequency down a few hundred Hz in the settings file. Or just
tune the VFO of the 10m radio a little until you are where you want to
be on the waterfall.
I have noticed the ROBOT-Beacon does turn on the NO-84 transmitter at
times. If you are not turning the satellite on, use more power. 40- 80
watts works for me most of the time. Expect your signal to be
noticeably weaker than the telemetry down at 312Hz.

My audio recording/reception of Astronaut Kjell Lindgren talking to
students from Dagget Montessori School in Fort Worth, Texas as heard
in Raleigh, North Carolina. For continuity, I recorded myself reading
the questions the students asked, and spliced them into this
recording.
I make videos of these receptions too, like this:

I received answers to questions 4 - 10:
4. How does the lack of gravity affect your blood flow?
5. At what age did you decide to become an astronaut and what inspired
you to do so?
6. On Earth, we see one sunrise and one sunset a day. How does it
change your sleep-wake cycle when you see a sunrise or sunset every 45
minutes?
7. Are there any mechanical or electrical changes in your equipment
from Earth's gravity to microgravity? For example, results from the

Hi!
Yesterday was a busy, and fun, day. Between the Tucson Hamfest in the
morning and over 300 miles of driving after the hamfest to operate from
3 other locations in 2 southern Arizona grids, it made for a fun day.
A good hamfest for AMSAT in the morning, and a long loop through southern
Arizona including a stop at one of the rarest grids in the continental
USA added to the fun.
I drove down to the hamfest, hosted at a school about 25 miles northwest
of downtown Tucson in the suburb of Marana, early in the morning. I was
setting up around 5am (1200 UTC), so I could be ready for the early-
morning crowds and also work the early SO-50 and LilacSat-2 passes from
the hamfest site. I was able to do that, and also work a couple of AO-73
passes later in the morning. During the morning, my AMSAT table was
visited by a group of students from the University of Arizona. They were
interested in learning about AMSAT's Fox project, as they are about to
start their own CubeSat project. Maybe we'll hear about their project in
the near future. Thanks to the Oro Valley Amateur Radio Club, the club that
hosted the hamfest, for providing AMSAT a space at the hamfest - a nice
space with a good view of the eastern sky, for the demonstrations.
After the hamfest and a quick stop for lunch, I decided to make a long
drive from the Tucson area out to the rarely-heard grid DM31. Since I
didn't leave the hamfest until almost 12 noon (1900 UTC), I knew I would
miss some really good passes that covered the east coast, but I still
wanted to make a run out that way. I have not been to DM31 in almost 5
years, and it turned out to be a perfect day to drive around southern
Arizona and be outside to work satellites.
On my way to DM31, I stopped along a highway in grid DM32re to work SO-50
and FO-29 passes just after 2100 UTC. The SO-50 pass was a shallow pass
favoring the east coast, and FO-29 basically went right over my head. I
stopped along a highway where I was not right next to the highway, and
worked these two passes. This location was on the western edge of the
Tohono O'Odham Nation reservation, which covers a large chunk of southern
Arizona. These passes went well, and I wasted no time stowing my gear after
the FO-29 pass went away to make it to my next stop.
I only had to drive about 45 minutes to reach my destination in DM31, the
visitor center at the Organ Pipe Cactus National Monument. This spot is
about 5 miles north of the USA/Mexico border, but a few miles inside DM31.
In my two previous trips to this grid, I operated at the Lukeville border
crossing, very close to the USA/Mexico border fence. Seeing so many Border
Patrol vehicles on the highways after leaving Tucson, and knowing the
situation just over the border in that area, I decided not to drive all the
way to the border crossing. Operating from the national monument's visitor
center was OK, even with the hills to the west that meant the most shallow
western passes were not workable.
At DM31, I worked 4 passes - two SO-50 passes, and one pass each on FO-29
and XW-2F. The first SO-50 pass, around 2245 UTC, was a high pass, but did
not stretch all the way to the east coast. I worked 13 station on this
pass. FO-29 came by about 15 minutes after the SO-50 pass, and this was a
shallow pass with maximum elevation of 5 degrees. I heard K8YSE/7 on this
pass, but did not work anyone. The last SO-50 pass around 0030 UTC added
just 2 more QSOs to the log. XW-2F, just after 0100 UTC, was probably the
best chance to work some stations further away from me to the east. I used
my SDRplay SDR receiver to hear the downlink, transmitting from one of my
FT-817NDs. I worked 4 stations, and then packed up. It was just after
sunset, and I did not want to stick around this area after dark - even at
the visitor center.
Before the last SO-50 pass I worked at 0030 UTC, I was visited by a US Park
Ranger - the law enforcement at national parks and monuments. We had a nice
15-minute chat, and I was never asked to produce any ID or paperwork for
my radio gear. Normally, when I operate from this area or other locations
near the USA/Mexico border, I'm visited by Border Patrol agents, but not
this time. As I was about to leave this area, a Border Patrol helicopter
flew very low over the visitor center heading away from the border area.
The drive from the Organ Pipe national monument to Gila Bend, a small town
along the I-8 freeway, is a 75-mile drive. On the way north, there are two
Border Patrol highway checkpoints, plus the road (Arizona 85) cuts through
the east end of an Air Force bombing range where stopping is not allowed
except for emergencies. I made the drive in about an hour and a half, and
that let me work two AO-85 passes from a McDonald's parking lot near I-8
in Gila Bend to wrap up the day's radio operating. Gila Bend is at the
north edge of grid DM32, the grid I worked from earlier in the afternoon
before I made it to DM31.
The first AO-85 pass I worked, just after 0300 UTC, was probably the
busiest AO-85 pass I have worked. I logged QSOs with 11 different stations,
and heard a few others I did not work. I used my SDRplay SDR receiver and
HDSDR software to hear the downlink, transmitting with my IC-2820H. I made
an RF recording of the pass, so I could decode telemetry and upload it
later. After the 0300 UTC pass, I had dinner, and then worked the western
pass at 0445 UTC for my final pass of the day. Four stations showed up at
that hour. When I ran the RF recordings from these passes through FoxTelem
this morning, I uploaded a total of 97 data frames to the AMSAT server -
a little more than half of them came from the earlier of the two passes.
When I made it home just before midnight (0700 UTC), I had driven 416 miles
since leaving home at 2.45am (0945 UTC). If I had only driven to the
hamfest and back home, I would have had less than 200 miles on the car. The
extra driving was nice, especially with the afternoon temperature staying
around 80F. I logged 24 QSOs at the hamfest on 6 passes (2 each on AO-73,
SO-50, and LilacSat-2), 15 QSOs when I stopped along that highway in grid
DM32 on SO-50 and FO-29, 19 QSOs on 3 passes in DM31 (2 SO-50 passes, plus
an XW-2F pass), and 15 QSOs on the two AO-85 passes in Gila Bend (DM32pw)
in the evening. I enjoy going to hamfests representing AMSAT, and the post-
hamfest road trip was a lot of fun.
I know there are a few who had hoped I could have made it to DM31 for
earlier passes yesterday. With the hamfest being the main reason I was in
southern Arizona, the post-hamfest travel was a bonus. I made sure to
stretch that into the evening, and that let me operate from a couple of
other grids (DM31, DM32) besides the grid the hamfest was in (DM42). I will
try to make another run to DM31, when I can work more passes that reach
both coasts.
All of my QSOs from yesterday's passes have been uploaded to Logbook of the
World. If you would like to receive a QSL card for QSOs with me, please
e-mail me directly with the QSO details. If you're in the log, I will send
a card. I have also posted my RF recordings and other files related to the
AO-85 and XW-2F passes I worked yesterday, available at:

Jerry,
Sorry for the tardiness in this post to the AMSAT-BB list. I heard you and
KO4MA talking during the 1715 UTC AO-85 pass this morning. I was listening
with my SDRplay receiver, HDSDR software, and Elk log periodic out in my
yard. I made an RF recording with HDSDR, and posted the RF recording where
you two were testing the satellite (along with the RF recording from the
1855 UTC AO-85 pass, and other files related to these two passes) in my
Dropbox space at:
http://dropbox.wd9ewk.net/
Look for the 20151108 folder with the name ending in DM43 to get to these
files.
Late in the 1715 UTC pass, I saw and heard AO-85 change back to the normal
mode with the FM transponder with slow-speed telemetry. I did not run
FoxTelem in real time during the pass, but made sure to run my RF recording
through FoxTelem after the pass to get the data I received up to the AMSAT
server. It was easy to see in the HDSDR waterfall the difference between
the normal mode with telemetry and the COR mode without any telemetry -
especially how the downlink transmitter ramps up to the nominal downlink
frequency, every time it fires up.
73!

What Bob forgot to mention about BRICSAT-1 is that it carries a set of
experimental electric thrusters from George Washington University. If you can
help recover BRICSAT so that its thrusters can be fired, you would be helping
to obtain performance data on the thrusters which could be valuable input to
future AMSAT mission proposals. The HEO satellite proposal needs a small
thruster for orbit maintenance. This satellite mission is important to AMSAT,
let's get out the AMSAT can-do spirit and help recover this satellite!

Hi all:
Just for information.
SWL report of AO-85 during its orbit #456 + 11mins at 09:39 UTC
Location: IN80CP.
Max. elevation during the pass: 7?
RXing with 9 element yagi + mast preamp, horizontal polarization.
No telemetry heard.
No beacon heard.
Is sat still on COR mode?
Usual dificulties to be repeated by the sat.
Usual fading.
But clear audio (My feeling that much clearer than when the sat is in
the standard modes)
Very good signal strength (Same feeling... Is this COR mode providing
more power than in the standard modes?)
Best 73s

For the purpose of the demonstration and development of CubeSats in the
technology of the
universities around the world, it had been scheduled to be launched all 50
satellites by
Cyclone-4 rocket belonging to Alcantara Cyclone Space, a joint venture
between the governments
of Ukraine and Brazil, on 1 February 2016 in the first plan. The launch plan
has changed, the
CubeSats are now expected to be shipped to the ISS in July 2016 with
deployment at a later
date. There are still also uncertainties, but I, JE9PEL investigated the
current frequencies
and summarized them in an Excel file. I intend to edit in the future this

That's a bit weird, isn't it? VK5HI reported telemetry at 6:25 UTC today:
http://amsat.org/tlm/ao85/201511082225427.txt
I coincide in the opinion that the audio is clearer without DUV telemetry.

Indeed it seems that AO-85 was in COR mode as it passed over Europe
about 11:10 UTC. Listened in SUWS websdr. Several Spanish stations on
the transponder, as today is holiday in some parts of Spain.

Hi all:
Now orbit #457 + 12 minutes
Double checked. No telemetry at all neither in this pass. EA1JM confirms
the same.Satellite was busy and several stations were making QSOs.
At least from my side, same comments and feelings as in my previous RXed
pass: Nothing have changed regarding the uplink issues and downlink
quality looks to be better (Both audio and signal strength) than when in
the normal modes.
Question: I understood that the uplink dificulties were related to some
issues regarding 67Hz reception on the sat. If the COR mode doesnt
handle 67Hz at all and is an "Open Squelch" mode... Should not "life be
easier" to be repeated by the sat?.

Hi all:
Just for information.
SWL report of AO-85 during its orbit #456 + 11mins at 09:39 UTC
Location: IN80CP.
Max. elevation during the pass: 7?
RXing with 9 element yagi + mast preamp, horizontal polarization.
No telemetry heard.
No beacon heard.
Is sat still on COR mode?
Usual dificulties to be repeated by the sat.
Usual fading.
But clear audio (My feeling that much clearer than when the sat is in
the standard modes)
Very good signal strength (Same feeling... Is this COR mode providing
more power than in the standard modes?)
Best 73s
