BID: $ANS-032.01

The Delfi-C3 control team has set up a WebSDR station at their 
satellite command ground station in Delft, The Netherlands. Their 
WebSDR station consists of receivers hooked up to a PC and then 
the internet to enable multiple users to tune in to different 
signals simultaneously.

At Delft one receiver is for VLF reception and one is currently 
used for the 70cm satellite segment. Amateur Radio users can 
access this unique experiment at http://websdr.pa3weg.nl/. Please 
note that the Delfi team may occasionally retune the receivers to 
experiment with them.

The hardware was built by Wouter-Jan Ubbels PE4WJ. The WebSDR soft-
ware was written by Pieter-Tjerk de Boer, PA3FWM. A beta testing phase 
was begun in November 2008 with a few selected stations. Upon comple-
tion of the test phase the software will be made available to the 
public on the WebSDR project at http://www.websdr.org.

Many thanks to Pieter-Tjerk de Boer, PA3FWM for providing this soft-
ware and Wouter Jan Ubbels, PE4WJ for building the receiver and pro-
viding the high sample rate sound card!

The Delfi-C3 Team's WebSDR receiver was used to copy and plot the 
downlink from the STARS satellite. Screen shots of this experiment 
can be viewed at:

DELFI-C3 in Science Mode

BID: $ANS-032.02

Wouter Jan Ubbels, PE4WJ reported that the Delfi-C3/DO-64 team
this week commanded the satellite into its science mode of operation.
After examination of telemetry and user reports the team concluded 
that the linear transponder is no longer operational. 

Delfi-C3/DO-64 has been operating in basic mode (a mode in which only
housekeeping mode is transmitted) for a number of months in order to
investigate this issue.

To make the best use of remaining satellite function the team switched 
the satellite back to science mode. This mode yields valuable science 
data about the Thin Film Solar Cell payload and the Autonomous Wireless 
Sun Sensor payload which are the primary mission goals. The satellite
will use the primary downlink at 145.870MHz, transmitting 1200 Baud 
AX.25 BPSK data. Note that the satellite reboots on 145.870 MHz whene
it comes out of eclipse because there is no battery on board. It is 
possible, that the satellite may reboot on 145.930 MHz backup downlink. 
If you hear Delfi-C3 / DO-64 on this frequency, your reports are highly
appreciated!

In contrast to basic mode operation where the downlink is on contin-
uously, downlink drop outs are likely to occur in science mode. It is
is possible that the satellite may not transmit during the entire pass
while in sunlight. If you hear the satellite, your reports are very 
much appreciated! The Delfi team regularly posts the satellite status 
on the Oscar status page at http://oscar.dcarr.org/ and encourage you 
to do so as well.

Delfi telemetry can be received using the RASCAL program, which is
available at http://www.delfic3.nl/rascal At this moment, the total
amount of frames has exceeded the 500000 mark which amounts to approx-
imately 72.14 MB reported by Amateur Radio stations.

SSETI Express on 437.250 MHz?

To All RADIO AMATEURS
BID: $ANS-032.04

Graham, G3VZV mentioned that Amateur Radio operators may just have a
a very small chance of also hearing signals from XO53 - SSETI Express.

SSETI Express was launched in November 2005 but, due to a failure 
within the power supply system on board, signals were only heard for 
a few hours. Investigations made after the launch indicate that it is 
just possible that the offending short circuit FET devices may, one day, 
go open circuit. This would allow power from the solar panels to again 
reach the electronics. It can be assumed that the batteries are pretty 
useless by now so it would only be likely to operate when in sunlight.

SSETI Express was on 437.250 MHz - the same frequency as is now being 
used by Japan's new PRISM satellite launched on January 23, 2009. If 
by any chance you hear any strange  noises on the frequency to please 
let Graham know. In this context, "strange noises" could be either 
short bursts of 9k6 data or even some very unusual "CW like" signals. 
If these signals are present you may be copying a sub 1 second burst 
of AX25 telemetry every 18 seconds or simple on/off telemetry compris-
ing 16 x 100msec carrier pulses which cycle either every 30 seconds 
or every 2 minutes.

Graham summarized, "Similar satellite returns have happened in the 
past!"

Via Amateur Radio Newsline Report 1642 -  January 30 2009

The K6DUE callsign of the late NBC Newsman Roy Neal is now the call 
of the International Space Station Amateur Radio Club.  According 
to ARISS International Chairman Frank Bauer, KA3HDO, the call letters 
will initially be used for ground station operations but may be used 
for other activities in the future.

For those not aware, Roy Neal, K6DUE, spent more than five decades 
as a broadcaster specializing in science and aerospace reporting for 
the National Broadcasting Company.  He is generally credited with 
convincing then NASA chief Jess Moore to permit ham gear to be flown 
on board the early space shuttle missions. The first of these was STS-9 
that carried Spacelab One and Mission Specialist Owen Garriott, W5LFL, 
who made the first-ever ham radio contacts from a spacecraft on-orbit.

After Garriott's successful flight, Neal and several others formed the 
group known as SAREX -- the Shuttle Amateur Radio Experiment.  Later 
called the Space Amateur Radio Experiment, it was a program that pro-
moted and supported the use of amateur radio by astronauts in low 
earth orbit aboard the United States Space Shuttle.  This, to com-
municate with other amateur radio stations around the world especially 
those in classrooms as a scientific demonstration.  It was superseded
by the Amateur Radio on the International Space Station or ARISS pro-
gram that we hear so much about today.

Roy Neal, K6DUE, passed away at age 82 on August 15, 2003, following 
open heart surgery.  On November 11th  2003 the Amateur Radio on the 
International Space Station organization announced an on-the-air event 
to commemorate Roy Neal's lifetime of achievements in ham radio.  Now, 
with the acquisition of his K6DUE call letters by the International 
Space Station Amateur Radio Club, Roy Neal's contributions to manned 
ham radio operations from space will live on in perpetuity.

1. School Contacts

An ARISS contact was completed with Castor Valley Elementary School 
in Greely, Ontario, Canada on Tuesday, January 27. A space club at 
the school was formed for grades 1-8. Students from this group asked 
questions of the astronaut. Students have learned about the ISS via 
the internet and videos and through guest speakers. They have been 
taught the correct radio protocol and have tracked and plotted the 
course of the ISS. All classes have taken part in space projects 
and activities. Media, members of the community, the school board 
and other dignitaries were invited to attend.

An ARISS contact was completed for CERAM EAI in Sophia Antipolis, 
Alpes Maritimes, France. The contact will take place on Thursday, 
January 29 via telebridge station VK4KHZ in Australia. CERAM Uni-
versity conducts research projects in aviation, engineering and IT. 
Amateur radio communications was introduced to students to prepare 
for the contact.   

Ecole & Collège Jean XXIII, a private primary & secondary school in 
Pamiers, France, completed an ARISS contact on Friday, January 30.  
Five hundred students, ages 3 to 15 years old, attend the school. 
Students in the third cycle classes (3rd - 5th grades) and those 
in their second year of secondary school have studied radio commun-
ications. Radio operators from "l'Institut de Développement des 
Radiocommunications par l'Enseignement" (IDRE) have introduced radio 
technology to the children. Topics included remote command use, 
introduction to Morse code, ham radio phone contact, distress beacon 
search, electronic kits, and different ham radio station possibilities. 
This ARISS activity has been incorporated into the educational sub-
jects of Astronomy, History of Space Exploration, Geography and Writing. 

Humber College Institute of Technology and Higher Learning in Toronto, 
Ontario, Canada has been scheduled for an ARISS contact on Monday, 
February 2 at 17:29 UTC. The school has concluded an extensive research 
period in how waves travel through space and the Earth's atmosphere and
plans to put theory into practice. It has assembled the primary ground 
station right on the main campus, and it is hoped that it will inspire 
future students in conducting similar studies. With help from the media 
department and a school contest, the school has been working to involve 
every student in this project. With over seventy thousand students, 
which include both full-time and part-time students, the college is 
excited to promote this project within the community.

Pilton Bluecoat Junior School in Barnstaple, Devon, England has been 
scheduled for an ARISS contact on Friday, February 6 at 14:48 UTC. The 
school has planned an event with the theme "Our Home in Space - The Final 
Frontier," in which students learn about Earth as part of the wider 
universe.  All classes took part in the initial selection of questions; 
the final questions were chosen by the school council. Students have 
studied the development of the ISS and the history of man in space. 
Older children have written press releases.  

Städtisches Gymnasium Herzogenrath in Herzogenrath, North Rhine-
Westphalia, Germany has been scheduled for an ARISS contact on 
Saturday, February 7 at 10:32 UTC. The school has an amateur radio 
club whose members initiated the ARISS contact. The students prepared 
a radio exhibition that was shared with the school. The English and 
History departments have also participated in this activity.  Stu-
dents competed in an essay contest and created projects related to 
the "Space Race."  Newspapers and television stations have been 
invited to cover the event.

College of Agriculture, Central Agricultural University in Imphhal, 
Assam, India has been scheduled for an ARISS contact on Sunday, 
February 8 at 10:06 UTC via telebridge station VK4KHZ in Australia.

2. Children's Hospital Contact Successful

On Tuesday, January 20, patients at the Children's Hospital of 
Eastern Ontario in Ottawa, Canada spoke with Sandra Magnus, KE5FYE, 
during an ARISS contact. The children asked 16 questions of the 
astronaut via telebridge station ON4ISS in Belgium. Due to the 
hospital's infection protocol, media was kept from the event and 
unable to access or interview the students directly.  A represent-
ative from another children's hospital in Calgary was present and 
was very impressed with the event; he plans to submit an ARISS 
application for his hospital.  The audio was fed into the EchoLink 
AMSAT and JK1ZRW servers and into the IRLP Discovery reflector 9010. 
EchoLink received 20 connections from 14 countries, including one 
link node and two repeaters. 

3. Astronaut Training Status

On Friday, January 23, Jeff Williams, KD5TVQ, received a refresher 
course covering the ARISS radio equipment and operations. Williams 
is scheduled to launch to the ISS in September and will take over 
as commander in November 2009.

4. General Voice Contacts

Mike Fincke, KE5AIT and Yuri Lonchakov, RA3DT made several general 
voice contacts over the last week.  Among those contacted were 
stations in France, Spain, Chile, Italy and the Netherlands.

5. ARRL QST Covers ARISS News

The American Radio Relay League (ARRL) printed 4 ARISS news items 
in its February 2009 issue of QST.

On page 12, the "In Brief" column (a "what's been happening at ARRL 
recently) mentions ARISS' 25th commemorative activities
 
"Inside Hq -- 2008 Year-End Review" (page 13) mentions that ARISS 
"celebrated its 350th QSO (contact)."
 
A story on pages 54-55, "Amateur Radio and Public Education Make for 
a Bright Future" is about a Kentucky high school teacher who included 
amateur radio in his science curriculum.  There is one small part 
about him being excited about his students being able to garner an 
ARISS contact.  
 
The "75, 50, and 25 Years Ago" column on page 102 shows the cover 
of February 1984 QST with Owen Garriott on the front, and the column 
lists two bullet items for the February 1984-25 years-ago section: 
the first being about Owen on the cover, and the second being that 
QST printed an interview of Owen, and it says: "We all hope that 
Amateur Radio will continue to be a part of the space shuttle missions."
