AO-51 New PL Operation Being Tested

AMSAT News Service Bulletin 108.02
April 18, 2010
BID: $ANS-108.02

AO-51 67Hz Access Tone Experiment in Progress

The AO-51 Control Team has enabled the new PL routine. This improved 
routine will turn the downlink on with an unsquelched uplink when it 
hears a 67 Hz tone. At present there is a tail of several minutes so 
the transmitter will stay on without hearing the tone.

AO-51 users are urged to program in a 67 Hz PL tone again, but this is
not absolutely required as long as someone else in the footprint has 
already enabled the satellite with the tone. It also means if you are 
the first person in the footprint (not very likely in North America, 
Europe, or Japan) you might not hear the satellite until after it hears 
67 Hz for a few seconds.

Mark, N8MH commented on the new operating mode, "The transmitter shuts 
off (for about a second, maybe less) after 2 minutes, even if people 
are talking with a 67Hz tone. So, a new 120 second period will not start 
until the current one ends."

Andre, ZS2BK observed, "On a south to north pass into ZS, the bird was 
off and was switched on with the tone. It stayed on for 120 seconds. It
goes off momentarily as a tone equipped station is transmitting."

Matching Funds Opportunity

The Dayton Amateur Radio Association (DARA) will match one-for-one 
any donations made to AMSAT between now and June 30, 2010 up to a 
maximum of $5,000. You can make your donation count even more.  
Now is the time to accept the DARA challenge. Please support 
"Getting AMSAT Back into Space" and help us raise the funds 
needed for our next satellite project.

AMSAT's Project "Fox" is a cubesat that will provide a 2 meter-70 
Centimeter FM transponder that will match the ground performance of 
AO-51. You can send your donation to: AMSAT, 850 Sligo Ave #600, 
Silver Spring MD 20910. If you prefer, you can call Martha at the 
AMSAT office (US call toll free at 888-322-6728 or 301-589-6062) 
and contribute with a credit card.

SO-67 Operation Expected to Resume Soon

AMSAT News Service Bulletin 108.05

SO-67 Operation Expected to Resume Soon

The SA AMSAT web page at http://www.amsatsa.org.za/ says, "Amateur 
Radio operation is expected to return soon. Keep an eye on the SA-
AMSAT web page. All requests for SO67 operation will be handled by 
SA AMSAT and schedules will be published on http://www.amsatsa.org.za. 
Details on how to apply for operation in your area will be announced 

This month saw the transfer of the control of the satellite from Sun-
space to the CSIR’s Satellite Application Centre at Hartebeeshoek. 
Sunspace will continue working on the commission of some of the ex-
perimental payload which include the NMMU string experiment, the DOC 
communication experiment and the VLF experiment from UKZN. 

Although a hugely successful mission thus far, the past six months 
have been challenging for Engineers at Sunspace and unfortunately not 
without incident.   

“We suffered a permanent loss of the Z-axis reaction wheel early on 
during commissioning” Jan-Albert Koekemoer commissioning engineer at 
Sunspace said. We adapted the  Attitude Determination and Control Sys-
tem (ADCS) algorithms so as to still allow for controlled imaging with 
the remaining two wheels - Yaw-control was then slightly impeded and 
the off-Nadir Roll angle limited to ±20°.”

”Due to a power system anomaly, we have also lost access to one of the 
two CCD control boards. Each control board interfaces to one three-
colour CCD. The board we lost contains the Green, Xantrophyl and Blue 
spectral bands. The remaining board contains the Red, Red-Edge and Near-
Infrared bands.”

”We recently also lost the Y-axis reaction wheel (most likely also 
due to a power distribution failure), this meant the loss of three-axis 
control, but amazingly we can still take high-resolution images as 
before."  An image captured by SUMBANDILASAT can be seen at:

Arecibo on 432 MHz Moon Bounce (still Time Today)

AMSAT News Service Bulletin 108.08
April 18, 2010
BID: $ANS-108.08

The Arecibo Observatory Amateur Radio Club will be putting the 
1000-foot radio telescope on the air for 432 MHz EME from 
April 16-18.

It can be heard with a small hand-held yagi pointed at the moon.
The scheduled times of operation are:

April 18: 1840 - 2125 UTC(Today)

Callsign: KP4AO

Tx Frequency: 432.045 MHz

Rx Frequency: 432.050 to 432.060+

Tx power: 400 W

Antenna gain: 60 dBi

System noise temp: 120 K (cold sky)

System noise temp: 330 K (when pointed at moon)

KP4AO can be heard with a small hand-held yagi pointed 
at the moon and a good receiver. A 15 dBi antenna and 
100 W will be enough to work us on CW.

Operators at KP4AO will do their best to work as many 
stations as possible. Each session will start with a brief 
announcement and CQ in SSB. SSB QSOs may continue for 30 
minutes to an hour, if the QSO rate remains high.

The mode will be shifted to CW as soon as it is judged that 
higher QSO rates would result.

We will listen for calls at frequencies 5-15 kHz higher than 
our own, and even higher if QRM warrants. Callers who 
s-p-r-e-a-d o-u-t are more likely to be copied.

If you've already worked us in any mode, please do not call 
again -- give others a chance.

If we call "CQ QRP", we will listen for stations running 100 W 
or less to a single yagi. Please do not answer such a CQ if you 
are running more power or have a larger antenna.

On April 18, if we reach a condition where most calling stations 
have been worked, and we judge that operating in the digital mode 
JT65B would produce a higher QSO rate, we will switch to JT65B.

Note that any of these planned operating strategies may be changed 
as circumstances dictate.

We are extremely fortunate to have been granted access to the world's 
largest radio telescope for this amateur radio good-will event. 
We look forward to working as many stations as possible in the alloted time!

Amateur Radio on the International Space Station (ARISS) Status Report
April 12, 2010

1.	Upcoming School Contact

An Amateur Radio on the International Space Station (ARISS) contact has been
for Jessup Elementary School in Houston, Texas on Monday, April 19 at 18:43
UTC. This 
will be a telebridge connection through ground station WH6PN in Hawaii. The
school has 
incorporated the ARISS activity into its curriculum, specifically focusing
on science, 
math, and language arts instruction across the pre-kindergarten to fourth
grade levels.

2.	Astronaut Timothy Creamer Speaks with Italian Students via ARISS

On Tuesday, April 6, on-orbit astronaut Timothy Creamer, KC5WKI participated
in an 
Amateur Radio on the International Space Station (ARISS) contact with
students from 
Scuola Primaria De Gasperi in Bari, Italy. The contact was held at the
Mediterranea della Scienza, which was designed to stimulate interest of the
public and especially youth, in fields of science and technology. To prepare
for the 
contact, students studied principles of radio communications and space
missions and 
were given a presentation on ARISS by ARISS mentor Francesco De Paolis,
IK0WGF. The 
event drew an audience of more than 100 students, teachers and guests as
well as 
members of the media. The contact audio and video were distributed
Europe and America by webcast, receiving 500 connections.

3.	ISS Ham Debrief Held with Astronaut Jeff Williams

Expedition 21/22 astronaut Jeff Williams, KD5TVQ participated in an Amateur
on the International Space Station (ARISS) debrief session on Friday, April
The feedback he provided on the ISS Ham radio equipment and school contacts
help the ARISS team improve program operations.

4.	ARISSat Presentation to be Given at Dayton Hamvention

Dayton Hamvention 2010 will be held at the Hara Arena Complex in Dayton,
Ohio on 
May 14 - 16. The American Radio Relay League (ARRL) and the Radio Amateur 
Satellite Corporation (AMSAT) will both man exhibit booths at the event.
Gould Smith, 
WA4SXM, AMSAT Project Manager for ARISSat-1, plans to give a presentation at

the AMSAT Forum titled, "Getting ARISSat-1 Ready to Fly."  The Dayton
is an internationally attended amateur radio convention that draws crowds 
of 25,000 annually. For more information on Dayton Hamvention 2010, 
go to: http://www.hamvention.org/

5.	Four Women in Space Hold Amateur Radio Licenses

Shuttle STS-131 launched on April 5, carrying three women into space: 
Dorothy Metcalf-Lindenburger, KE5DAT, Stephanie Wilson, KD5DZE and JAXA 
astronaut Naoko Yamazaki, KE5DAS. Upon docking with the ISS, they joined 
Expedition 23 crew member Tracy Caldwell-Dyson, KF5DBF. This was the first 
time that four women have been in space, and all are licensed hams. 
Caldwell-Dyson will participate in her first Amateur Radio on the 
International Space Station (ARISS) contact with Jessup Elementary 
School in Houston on April 19. Let's hope they like to make random 
contacts to give the Amateur Community some excitement.
