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:

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?

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 & Coll=E8ge 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 D=E9veloppement 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. =
St=E4dtisches 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 =

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

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 =
