AMATEUR RADIO GROUP TO FLY BALLOON FLIGHT FROM HILLSBORO TEXAS AIRPORT
The next mission number 17, named =93Summer Time Blues=94, to be held by th=
e North
Texas Balloon Project (NTEXBP) is planned for launch about 8:30 am on Augus=
t 8,
2009 from the municipal airport in Hillsboro, Texas, just south of Fort Wor=
th
and Dallas. Back up date is August 15, 2009. Two payload packages containing
sensors and amateur radios will be carried to nearly 100,000 feet in about =
90
minutes by a helium balloon and return via parachute in about 50 minutes.
Mobile recovery teams will use position reports from the onboard GPS and AP=
RS
transmitter on 144.390 MHz and radio direction =
finding techniques to recover the
payloads.
Pre-launch activities will begin about 7:00 am with the HF Launch Net on 72=
60
+/- 5 kHz, LSB beginning around 8:00 am. A cross band repeater will be
activated soon after launch. Uplink is 445.800 =
MHz and downlink is 147.560 MHz.
Handheld VHF radios and scanners can receive =
the downlink easily. At the peak
altitude ham radio operators from Texas, New Mexico, Oklahoma, Arkansas,
Louisiana, and Kansas can contact each other using the cross band repeater.
The radios used normally have a range of about 5 to 10 miles, but that range
will be extended to about 500 miles at the peak altitude. At the peak altit=
ude,
the curvature of the earth is visible. Digital video is recorded for later
playback. APRS packets transmit the balloon's location about once a minute.
NTEXBP's Tommy Davis said, "In past operations we did the launches for fun =
and
the enjoyment of flight. It involves many different facets of amateur radio=
and
thus a project that many types of amateur radio operators can enjoy togethe=
r.=94
There is also an educational component utilized by scouting groups, because=
it
involves orienteering and can be counted toward several different merit bad=
ges,
as well as by teachers for science experiments. Davis said, =93Area scout t=

Castor and Pollox, two satellites in the Atmospheric Neutral Density Experi=
ment
(ANDE) program were successfully deployed from STS-127 after it undocked fr=
om
the International Space Station
The ANDE mission consists of two spherical spacecraft fitted with
retro-reflectors for satellite laser ranging (SLR). The constant and
well-determined cross section and surface properties of the ANDE spacecraft
provide an ideal set of objects for monitoring atmospheric drag and the
calibration of space surveillance network (SSN) assets both radar and optic=
al.
Castor
Castor is a 19 inch diameter aluminum sphere with a mass of 63 kg.
The satellite has several different types of sensors. There are two main
sensors, a Neutral particle wind and temperature spectrometer and an ion ma=
ss
spectrometer. A group of college students designed and built a MEMS sensor
payload to test
some commercial gyroscopes and a magnetometer. There are also six light sen=
sors
and six temperature sensors mounted in the satellite hemispheres.
Pollox
The Pollux satellite was originally to be a passive satellite with
retroreflectors for laser ranging. It has been =
turned into a high school student
project involving several schools in the Fairfax County, Virginia area.
The electronics is based on cubesat hardware developed at the Naval Research
Laboratory and Stensat Group LLC.
The communications board contains the transmitter and receiver. The transmi=
tter
operates at 2 meters and can put out up to 1 watt of signal. Power level is
adjustable. The transmitter can operate at 1200 =
baud AFSK and 9600 baud FSK. The
transmitter uses the AX.25 protocol. An experimental FX.25 protocol will be
tested that adds forward error correction capability to the AX.25 protocol =
and
still allows typical TNCs to decode the packets.
Both satellites will transmit on 145.825 MHz. Additional details about the
telemetry format, as well as the FX.25 and GMSK experiments can be found at

Amateur Radio Newsline 2009 "Young Ham of the Year" Announced

"Wow! Oh, my God. All my friends here at Seabase are going to be really
impressed. Oh, my God!"
And, that's how it sounded when we caught up with Andrew Koenig, call
letters KE5GDB, by cellphone at the Boy Scouts of America Seabase in Key
West, Florida, where he had just arrived with members of Troop 848 from
Houston for a week of scuba diving adventures.
The Life Scout, who is just shy of his 16th birthday, is working to earn
the Eagle rank and was ecstatic to learn he had been chosen for special
recognition by the Amateur Radio Newsline. Before telling him he had been
selected as the Young Ham of the Year, we asked Andrew how he might feel if
he were to receive such an award. He said it would be a nice honor to share
with his mentors, including his award nominator Nick Lance, call letters
KC5KBO, who has helped several NASA astronauts earn their ham tickets.
"Young Ham of the Year would probably go in the book of things that I've
done in ham radio that they are really impressed with," Andrew said. "It
would just mean a lot to me.
"Nick Lance, he hasn't really been pushing me to do anything. A lot of the
stuff I discover on my own. But, he's one of the big roles, one of the key
aspects in ham radio and it would give him a really good feeling to know
that one of his students went on to get youth ham of the year."
Andrew holds a General class license and passed the test for his first
ticket back in 2005 while a sixth-grader at the Westbrook Intermediate
School in Houston where Lance - who is retiring in August from the Johnson
Space Center - teaches an amateur radio license class.
Andrew is the son of Joe and Lauri Koenig of Houston. Joe holds the call
letters KE5JQA and got licensed as a result of Andrew's interest. Andrew
also has a younger brother, Kyle.
Among the achievements Andrew has accomplished is helping with an Amateur
Radio on the International Space Station (ARISS) contact at the Westbrook
Intermediate School.
"I actually helped test a lot of the equipment for the contact, since it
was a telebridge contact," Andrew recalled. "The station that was actually
contacting the ISS was in California, I believe.
"And, we were in Clear Lake, Texas. So, for some reason the phone patch
wasn't working properly. So, I had to actually go into one of the school
phones and test that - I think about 15 minutes worth of testing before the
contact started. And, finally right on time, we got it going again and
everything was working just fine."
The contact with Astronaut Clay Anderson, who holds the ham radio call sign
KD5PLA, was a success - thanks to Andrew.
Andrew also helped facilitate a terrestrial contact between Astronaut Chris
Hadfield (ham radio call letters KC5RNJ and VA3OOG) and students at two
Canadian schools using an Internet Repeater Linking Project (IRLP) node he
had built and placed in his bedroom closet.
Andrew, who enjoys VHF and UHF operations, tried and tried and was finally
successful in making his own contact with the space station using his
handheld radios and portable directional antenna. He also has participated
in training astronauts at the Johnson Space Center on ARISS contacts with
schools, conducting simulated contacts with them, playing the role of the
school students.
Andrew has also been quite active with public service events through the
Clear Lake Amateur Radio Club in suburban Houston where he is immediate
past vice president. He is also a member of the Seabrook Citizen's
Emergency Response Team.
Among his other achievements is creating his own bicycle mobile setup:
"I had tried putting a handi-talkie on my bike and I wasn't impressed with
the results because the rubber duck just didn't get out as far as I wanted
to," Andrew recalled. "A couple months before, I had ordered my first
mobile rig (radio), the FT-7800.
"And, actually a couple weeks before I decided to put it all together on
the bike, I had bought a brand new gel cell battery. So, I thought, you
know, hey I've got this remote that came free with the radio, I've got the
battery, I've got an antenna, I got everything I need to make it happen.
So, I just mounted it all on the bike with zip ties and I had 50 watts
mobile on a bike for VHF and UHF."
That attracted some attention from CQ magazine, which was looking for photo
ideas for its 2008 calendar. Photographer Larry Mulvehill (WB2ZPI) visited
Houston and Andrew's bicycle mobile became the calendar photo for September
2008. He and his bedroom-closet IRLP node will be featured the cover of the
September 2009 issue of CQ magazine.
Andrew is going into his sophomore year at Clear Lake High School where he
is a member of the school's marching band. He is also into computers and
creating websites and he maintains his own website started when he was in
middle school. Check out www.thathamkid.com. It offers kid-friendly
information about ham radio, along with a jokes page and a lot more about
Andrew's activities in amateur radio - including his working satellites.
His mentor and nominator for this award, Nick Lance, KC5KBO, summed it up
best when he said: "Andrew has truly been an outstanding student of
amateur radio.....He is an inspiration both to his fellow students and to
hams of all ages."
Award Ceremony
The 2009 Amateur Radio Newsline=99 "Young Ham of the Year Award" will be
presented to Andrew Koenig, KE5GDB, on Saturday, August 15th, 2009 at the
Huntsville Hamfest in Huntsville, Alabama. As the 2009 "Young Ham of the
Year," Andrew will receive -- courtesy of Vertex-Standard -- an
expense-paid trip to the Huntsville Hamfest, along with a gift of Yaesu
brand ham radio equipment. CQ magazine will treat him to an expense-paid
week at Spacecamp Huntsville, and will present Andrew with a variety of CQ

DRAGONSat, the Dual RF Astrodynamic GPS Orbital Navigator Satellite, was
deployed from from the cargo bay of STS-127 after the shuttle departed from=
the
International Space Station. The DRAGONSat mission consists of two satellit=
es,
BEVO-1 and AggieSat-2.
BEVO-1 Downlink Information:
Beacon Mode
Downlink Freq: 437.325 MHz
Modulation: FM, 200mW, Morse Code, ~20 WPM
Data Mode
Downlink Freq: 437.325 MHz
Modulation:
GMSK, 1W, 9600 baud, AX.25 (default)
FM, 1W, Bell 202, AX.25
http://www.utexas.edu/news/2009/06/09/picosatellite/
AggieSat-2
http://aggiesat.org/Home
436.250MHz
AggieSat2 operating mode uses a proprietary modem
protocol as the main radio is a COTS data modem. It appears the only way
to decipher the code is to have a model MHX425 that can speak the
proprietary language. The radio data rate is actually at 19200 bps.
Initial indications are that it appears Bevo and AggieSat are stuck together
right now. We are looking for aliveness confirmation until we can get the u=
nits
in a stable state.
