OSCAR Numbers Assigned for CubeSats QB50p1 and QB50p2
In an email to Mr. Wouter Weggelaar PA3WEG, AMSAT-NL and Mr. Jeroen
Rotteveel, ISIS CEO, OSCAR Number Administrator William A. (Bill)
Tynan, W3XO, announced,
"I have received your request for OSCAR Numbers for CubeSats QB50p1
and QB50p2 and from everything I can determine these spacecraft meet
all of the requirements necessary to receive OSCAR numbers.
"Therefore, by the authority vested in me by the AMSAT-NA President,
I hereby confer the designation European OSCAR 79 to CubeSats QB50p1
and European OSCAR 80 to CubeSat CubeSats QB50p2. These designations
can, of course, for convenience be shortened to EO-79 and EO-80.
I, and the entire amateur satellite community, hope for successful
missions for both EO-79 and EO-80 and congratulate AMSAT-NL and the
ISIS team as well as all who contributed to these new Amateur Radio
satellites for their success in building, testing and launching these
new OSCARs."
[ANS Thanks Bill W3XO and AMSAT-NA for the above information]

Reception of the One Millionth Packet from FUNcube-1
Many stations have been receiving the telemetry transmitted by
FUNcube-1, which has now been in orbit for 221 days. The spacecraft,
which has been operating nominally since launch, is providing on-
board health and science data for the many schools and colleges who
are already participating in the project around the world.
Since launch, data has been received by more than 650 stations
around the world and today our online Data Warehouse received its one
millionth packet of information. The Warehouse is now storing more
than 256MB of telemetry which is available for educational and
research use.
We have been successful in capturing almost 25% of all the telemetry
transmitted including almost all of the Whole Orbit Data. This
success is a great tribute to our designers of the Flight software,
the Dashboard programme and the matching Data Warehouse.
We are also immensely grateful to all the schools, colleges, radio
amateurs and other listeners who are providing this data and want to
encourage everyone to continue to listen to FUNcube-1 and to upload
the data to the Warehouse. This will help enable the project to
continue to provide a complete and current data set for analysis.
We would, of course, also love to have additional receiving stations
in the FUNcube Ground Station Network. This applies especially to
anyone near the poles or who is located on an island in the middle of
ocean. Their involvement would help us improve our rate of data
capture still further.
Our records show that there were three stations who actually managed
to upload the same one millionth packet to the Warehouse today. They
are G0EID, OM3BC and DL3SER. If they could contact "operations at
funcube.org.uk" we will arrange them to send them a small prize to
honour their contribution to the project.

WD9EWK - 2014 Field Day Report
Even though I only worked the radios for a few hours on Saturday,
the 2014 Field Day was another fun time to be on the radio. I had
two objectives for this weekend - try to make a QSO with NA1SS,
and try a new radio on HF - which I was able to do. I was on some
satellite passes, making a couple of QSOs, which I'll submit to
both ARRL and AMSAT.
Knowing that the ISS would be passing by within minutes of the
start of Field Day, I was set up in my back yard for that. I used my
normal FM satellite setup (IC-2820H, Elk log periodic), with the
power cranked down to 5W to fall in the 1B QRP classification I
normally operate for Field Day, and was ready to go. About 5
minutes into the pass, and after hearing other stations' calls from
NA1SS, I heard my call coming from there. Within seconds, I was
getting e-mails, SMS messages, and tweets from friends who also
heard that. A nice way to start Field Day! I listened to the rest of
the pass, and recorded it. I was on the next ISS pass at 1952 UTC,
hoping to hear anything from the ISS on 70cm (around 437.550
MHz) while recording the 145.800 MHz downlink. Lots of activity
on 2m just like the earlier pass, but nothing up on 70cm. Did
anyone hear anything from the ISS on 70cm during Field Day?
A few hours later, with more shade in the back yard, I broke out the
HF setup. An FT-897D with autotuner and its internal battery packs,
set to 5W transmit power, and a Buddipole portable dipole with its
mast and tripod. Before I started on the satellites in late 2005, I
used to do a lot of portable HF operating, so it took no time to get
the antenna up and the radio ready to go. Although I heard Field
Day activity on most HF bands (10m was surprisingly quiet in the
late afternoon), I ended up working 15m and 6m SSB to get a few
QSOs.
I tried to work FO-29 during a western pass around sunset, but could
not get through with my normal SSB satellite setup - two FT-817NDs,
Elk log periodic. Lots of activity, with some who sounded like they
may have been overpowering the transponder a bit. Around 0400 UTC,
9pm for me in Arizona, there was a western SO-50 pass where I was
able to break through with my IC-2820H at 5W and Elk log periodic.
Lots of twisting the antenna around, trying to keep up with the
satellite and hear myself on the downlink. I made two QSOs there -
one that counted for QSO points and the satellite QSO bonus with
VA7VW, and the other was to respond to W6KA calling me. I did not
score the second QSO. I heard two other stations calling me, but
could not get back to them and complete those QSOs with so many
stations trying to get through. Some were not using PL tones on the
SO-50 uplink, which only made the situation worse.
I also wanted to make an SSB satellite QSO, so I tried AO-73 about
an hour later, at 0500 UTC. A high pass for me, I was able to make a
QSO with W5MSQ before another strong station overpowered the
transponder. I was using my two FT-817NDs and Elk log periodic for
the SSB pass, staying with my normal SSB satellite configuration
instead of getting the FT-897D set up for SSB operation. This was the
last QSO in my Field Day log.
I have already sent off my QSL request for the NA1SS QSO. Since I
recorded the audio from those two passes, I made slideshow videos of
them. The first pass, or the 1815-1822 UTC portion I could hear, can
be found on YouTube:
https://www.youtube.com/watch?v=1QC3l6NplbM
I removed the first couple of minutes of my recording, since it only
had my calls to NA1SS, and one unreadable response from NA1SS.
By the way, did anyone else record this ISS pass? Especially if you
are on the west coast? If so, please e-mail me directly.
My slideshow video of the later ISS pass (1953-1957 UTC) is at:
https://www.youtube.com/watch?v=AxsIzal68VM
This was a shallow pass here, with maximum elevation of only 8
degrees, so this was a bit shorter than the earlier recording and
slideshow video.
I had the audio recorder sitting near the IC-2820H for the first pass,
so it could pick up the speaker audio and my voice. For the later
pass, I had a patch cable running between the speaker jack on the
TH-D72A HT and the mic jack on the recorder, since I was not
planning to work the later pass on 2m. I had my Elk log periodic
antenna routed through a diplexer, so the 2m side was going to the
HT and the 70cm side to the IC-2820H, in the hopes of working
NA1SS on 70cm and recording the audio on 145.800 MHz.
Another summary of my Field Day activity, including some photos,
can be seen at:
http://www.arrl.org/soapbox/view/8943
I'm hoping to get out of town for next year's Field Day, which is
what I normally do. It is fun to work with a portable setup, but it
would be better if the outside temperature was not as hot as it
was in Phoenix on Saturday afternoon (108F/42C at one point,
in the shade of my back yard!).

ISS Contacts makes 2014 ARRL Field Day, One to Remember!
One of the highlights of this year's ARRL Field Day was a myriad of
voice contacts offered up by the International Space Station (ISS).
Through the efforts of crew member Reid Wiseman, many anxious ham
radio operators had the experience, perhaps for the first time, of
speaking with an astronaut orbiting Earth on board the ISS.
After an announcement on Tuesday, June 24, of possible voice
contacts from the ISS during the upcoming weekend, many Field Day
stations across the U.S. set up tracking equipment, radios and
antennas, vying for a brief chat with an orbiting astronaut.
Through various social media outlets, hams were able to track where
ISS voice transmissions were being received and in most cases, which
Field Day stations had made contact.
One group that was fortunate enough to connect with the ISS were The
Boy Scouts of Raymore, MO, Troop 32. Ham operator, Jim Reicher
comments ... " I bet the boys could be heard up in orbit even without a
radio when Reid answered our call!"
Field Day is held annually during the 4th weekend of June and is
sponsored by the American Radio Relay League or ARRL. The main
purpose of Field Day is to allow ham radio operators a chance to
practice their emergency response capabilities and serves as a
contest for Field Day stations to contact as many other Field Day
stations as possible within a designated 24 hour period.

UKube-1 Launch Information
UKube-1, the UK Space Agency's first CubeSat, carries a set of
FUNcube boards with a linear transponder and educational beacon. The
launch is scheduled from Pad 31/6 at Baikonur in Kazakhstan on
Tuesday, July 8, 2014 at 15:58:28 UT and to be deployed from the
final stage of the Soyuz-2-1B/Fregat-M launch vehicle at 18:32:42 UT.
The UKube-1 Operations Team has just issued their Launch Briefing.
This is accompanied by a spreadsheet showing the anticipated UK
passes for the first orbits together with a worksheet showing the
telemetry equations.
These documents can be downloaded at http://funcube.org.uk/news/
UKube-1 carries a number of experiments and payloads and also the
FUNcube-2 transponder and telemetry sub-system. This is intended to
support the current, very successful, operations of FUNcube-1 and to
provide an even better operational capability for schools and
colleges to use for hands on educational outreach around the world.
Further details of the educational outreach opportunities are
available here http://funcube.org.uk/education-outreach/
When the FUNcube-2 sub-system is activated, the 1k2 BPSK telemetry
will be downlinked on 145.915 MHz in the same way as already happens
with FUNcube-1.
A new FUNcube-2 Dashboard UI will be released shortly. This will
integrate directly with the existing FUNcube Central Data Warehouse
and existing usernames and authorisation codes can be re-used.
When the transponder is activated, the downlink passband will be
145.930 to 145.950 MHz and the uplink passband will be 435.080 to
435.060 MHz.
It is anticipated that the FUNcube sub-system may be tested for
short periods during the next few weeks depending upon how the LEOP
plan progresses.
AMSAT-UK personnel will be supporting the UKube-1 operations team at
Chilbolton during the immediate post launch period and will be
ensuring that regular status reports are made available via the
#cubesat IRC channel.
A web client is available at
http://webchat.freenode.net/?channels=#cubesat
AMSAT-UK and their colleagues at AMSAT-NL, are delighted that UKube-
1 is carrying this FUNcube sub-system and wishes every success to the
UKube Operations Team and to all the many contributors to the project.

Space: Guiding Your Way
World Space Week 2014 will be all about satellite navigation. In
this decade we see the number of satellite navigation systems grow
from one (GPS) to many (Galileo, Glonass, Beidou). At the same time
we see the number of applications for humanity rapidly increase too.
The relevance of positioning, navigation and timing from space is
much larger than many think. 2014 is a great year to highlight these
applications and benefits by choosing it as the central theme for
World Space Week.
We aim to inspire as many event organizers as last year with this
new theme. We are working with our partners in the space and space
applications industry to help us collect education and other material
for events. Please keep an eye on this website for more news soon.

Hi All,
I have a Yaesu G5400b controller with a kenpro az/el rotor. From my
understanding, yaesu was taken over by kenpro and the parts inside the az/el
rotor are the same as in a yaesu 5400 setup. Anyway, my rotor is in need of
repair and it seems there is a shortage of people who do these repairs, not
to mention have parts on hand to make the repairs (apparently replacement
parts from yaesu seem to be in short supply). Can anyone recommend a
technician for this who might have the parts?
Thanks,

Tim/all- I did a repair on my G5500 el rotor.? I needed a position pot-it
was available through Yaesu parts right away.? Depending on what you need to
have done, your mileage may vary.? You could always ship the whole thing to
Yaesu.? You can get lots of advice here on the bb.

Subject: [amsat-bb] az-el rotor repair
Hi All,
I have a Yaesu G5400b controller with a kenpro az/el rotor. From my
understanding, yaesu was taken over by kenpro and the parts inside the az/el
rotor are the same as in a yaesu 5400 setup. Anyway, my rotor is in need of
repair and it seems there is a shortage of people who do these repairs, not
to mention have parts on hand to make the repairs (apparently replacement
parts from yaesu seem to be in short supply). Can anyone recommend a
technician for this who might have the parts?
?
Thanks,
Tim

International agreement requires that objects in orbits lower than 2000 km
must exit that region within 25 years after end of mission. Objects in orbits
above 2000 km can remain there for longer than 25 years in a "disposal orbit",
but only a few missions have the excess propulsion capacity to reach that
orbit. Some US Government missions have disposed of upper stages to a higher
orbit to avoid the need to issue a Notice to Airmen concerning the falling
debris hazard. At least one polar orbiting weather satellite launch sent the
upper stage on an Earth escape trajectory for disposal.
It would seem that the Dnepr orbit is still too low to satisfy the
international requirement.

NASA is considering a revision to this policy to specify a total lifetime in
LEO of no more than 30 years regardless of mission lifetime.
Other interesting facts from Scott Hull's July 1 colloquium at NASA Goddard
include:
1. There are about 22,000 objects larger than 10 centimeters in the NORAD
database, an estimated 500,000 objects between 1 and 10 centimeters which are
too small to track, and millions of objects less than one centimeter. The
Chinese Fengyun 1C disintegration in 2007 produced about 2850 trackable pieces
of debris. The new S-band space fence will be capable of tracking objects
larger than 5 centimeters when it becomes operational in 2018.
2. There are about 4000 dead satellites on orbit, and about 1000 active
satellites.
3. The debris population has peaks at 750, 900 and 1400 km. You would have to
go to Saturn to find a worse debris environment than that of a 750 km Low
Earth Orbit. Science missions can be difficult when you live in a minefield.
4. Most spacecraft disintegrations are caused by battery and pressure vessel
explosions. Nickel hydrogen batteries are most susceptible to explosion but
NiCd and lithium ion batteries can also explode. A lithium ion battery must
NEVER be recharged after it has been fully drained. Rocket bodies left in GTO
are subject to explosion when the perigee height dips low enough to begin
atmospheric heating, which can cause remaining fuel in the tanks to explode.
Modern mission design requires that batteries be disconnected from solar
arrays and fully discharged and pressure tanks vented to space at the end of
the satellite mission.
5. Space is still pretty big. We have been lucky so far. Statistics predict
another eight or nine major collisions in the next 40 years with just the
current population of debris.
6. The movie "Gravity" did have a science adviser, and they did get a few
things right, namely that there were no loud sounds when the debris struck the
shuttle, and objects with lower area to mass ratio arrived first. Nevertheless
most NASA folks still consider the movie to be a comedy. If you have the DVD
there is an additional 20 minute documentary video about orbital debris on the
disk.

Hi Ted,
Add the following line to Doppler.SQF somewhere in the data section (use
paste and copy):
LO-78,435175.5,145950,FM,FM,NOR,0,0
I don't know whether the frequencies are exact. To check that (while the
sat is in range) click the SatPC32 control "V" to "V+", then open menu
"CAT" and with the "Downl. Corr." controls correct the downlink
frequency and save the found value in Doppler.SQF.
You may also add the following line to AmsatNames.SQF:
39569 98067EN LO-78
Then the program will display LITUANICASAT-1 as LO-78 if you use a Keps
file that still uses LITUANICASAT-1 as satellite name, for example the
Celestrak file cubesat.txt.
Both files can be opened and edited from the SatPC32 menu "?",
"Auxiliary Fies".
For detailed instructions read the FAQs file (sect. 1a) with a tutorial
by Wayne Estes, W9AE.

Thanks for that Dan, can you just confirm that the millions of items of
debris that NASA was referring to are naturally occurring chunks of rock ?
As you mention Weapons Testing in space has produced thousands of debris
pieces in orbits around 800 km and below.
