BID: $ANS-259.01

The Delfi-C3 team has been informed by its launch broker that the 
launch of Delfi-C3 has been moved to December, 2007.

The two major factors that have contributed to the postponement of 
the launch are weather and the Indian launch schedule. The weather 
effect on the launch is the typhoon season in India, which lasts 
from mid-October until December. The launch schedule is dependent
on mission priorities.

In the meantime the Delfi-C3 team will continue to work on futher 
testing parts of the satellite and preparing for the operations 
phase. As soon as more information regarding the launch of Delfi-C3 
is available it will be available on the Delfi-C3 website.

For downloads related to the press presentation (promotional movie, 
pictures, presentations) please go to http://www.delfic3.nl/press/

Delfi-C3 will have a telemetry downlink in the amateur satellite 
segment of the VHF amateur radio frequency band. Telemetry decoding 
software will be made available to participating amateur radio oper-
ators and universities which allows them to decode and display real 
time telemetry. This software will allow for uploading received tele-
metry date to the central Delfi-C3 ground station via the Internet 
for data processing. The Delfi-C3 team would like to invite all 
interested radio amateurs to receive, decode and forward telemetry 
data to the Delfi-C3 ground station.

Delfi-C3 includes a mode UV linear transponder. The satellite will 
be in telemetry only mode for approximately the first three months 
of the mission, after which it is switched to transponder mode.

Delfi-C3 Frequencies:

+ Primary telemetry downlink: 145.870 MHz 1200 Baud BPSK AX.25 400mW
+ Backup telemetry downlink:  145.930 MHz 1200 Baud BPSK AX.25 400mW
+ Linear transponder passband downlink: 145.880 - 145.920 MHz 
  (inverting) 400mW PEP
+ Linear transponder passband uplink:   435.570 - 435.530 MHz
+ Transponder mode beacon: 145.870 MHz CW (10dB below transponder PEP)

Drew, KO4MA, AMSAT-NA Vice President of Operations described the AO-51
Satellite Schedule for September.  Drew said, "We are currently running 
370 mW on TXA (435.150) and 630 mW on TXB (435.300). Power levels will 
continue to increase as eclipses get shorter, leading up to 10 weeks of 
continuous sun in early 2008."

Drew continued, "These are going to be interesting times. Keep in mind 
that anytime we have something other than telemetry running on TXA 
(i.e. L/U repeater), we may have to interrupt it occasionally for tele-
metry and satellite maintenance. Our lead command station, Gould WA4SXM,
 has been doing an outstanding job of squeezing every last drop of power
 for the downlinks."

AO-51 just completed 5 days of Mode L/S FM repeater operation.  The 
schedule for the remainder of September 2007 is as follows:

September 14 - September 17

FM Repeater, V/U
Uplink:   145.920 MHz FM, No PL Tone
Downlink: 435.300 MHz FM
Downlink: 435.150 MHz FM, 9k6 Telemetry Only

September 17 - September 21

SSB/FM Repeater, V/U
Uplink:   145.880 MHz USB
Downlink: 435.300 MHz FM
Downlink: 435.150 MHz FM, 9k6 Telemetry Only

September 21 - October 1

FM Repeater, V/U
Uplink:   145.920 MHz FM, No PL Tone
Downlink: 435.300 MHz FM

FM Repeater, L/U (subject to interuption for satellite maintenance)
Uplink:  1268.700 MHz FM, No PL Tone
Downlink: 435.150 MHz FM

As part of the Amateur Radio Expo at the Los Angeles County Fair,  
AMSAT member Clint Bradford, K6LCS, is manning an AMSAT booth. 
The Expo runs weekends throughout the Fair.

"It's been an AMSAT week," Clint reports. "I gave my "Working AO-51  
with your HT" presentation Friday night at the annual HAMCON  
conference in Torrance. We had 62 people in attendance, including  
Gordon West and Cathy Gardenias. And right after that presentation,  
we had a great pass of AO-51 that we worked from the top of the  
conference hotel's parking structure.

"Then on to the LA County Fair for all day Saturday and Sunday.  
Amateur Radio is well-represented here, with over 300 feet of booth  
space. Our booth is a 10x10 E-ZUP, with a slideshow running with  
photos and "stimulating" information. Handouts include a special  
"Fair Edition" of AMSAT News, and other material.

"If you are planning a trip to the Fair, we are set up outside  
between Commercial Buildings 4 and 6."

The Los Angeles County Fair runs September 7-30 this year. It is the  
largest county fair in the United States and retains its impressive  
ranking of fourth among the top 50 fairs and festivals in all of  
North America. The all-time record attendance was 1,612,097 over 24  
days in 1991. Fair attendance in 2006 was the highest since that  
record-breaking year, clocking in at 1,427,656. For more Fair  
information, their Web site is... http://www.lacountyfair.com

Three Satellites Spur Activity on 145.825 MHz Packet

BID: $ANS-259.04

The ARISS system aboard the International Space Station has frequently
enabled its packet digipeater for APRS on 145.825 using the path of 
"VIA ARISS".

Additionally, by mid-September PCSAT-1 should enter a FULL SUN
OPERATING PERIOD.  This may present a period of a few weeks 
when we will have THREE APRS satellites flying in constellation: 
ISS, PCSAT-1, and ANDE, all operating 145.825 MHz.

This will assure over 18 passes per day.  And since they all
respond to the same path "VIA ARISS" then which satellite is in
view is transparent to the user. Two-hop paths via ARISS,ARISS 
might also be possible.

Bob, WB4APR noted, "In order for the global APRS internet system 
to capture all these packets, we do need volunteer ground stations 
to place an IGATE to monitor all packets on 145.825 MHz downlinks.  
In many cases, a simple omni antenna connected to APRS is all that 
is needed."

Successful packet digipeating on 145.825 can be seen on either: 
http://www.ariss.net or http://pcsat.aprs.org

Bob added, "We are also working on getting GO-32 enabled for APRS
operation at 9600 baud.  But since it uses different uplink and
downlink fequencies, it cannot be used for multiple-APRS-satellite 
operations."

+ Clive, G3CWV reports from Hitchin, North Hertfordshire, in the UK that
  nothing has been heard from OSCAR-11.  The satellite is operational in
  sunlight but the current eclipses ended on August 20.  Prior
experience
  with OSCAR-11 suggest that operation should have been restored at this
  point.  Clive would appreciate any reception reports of the satellite. 

  Please post to AMSAT-BB or directly to g3cwv@amsat.org. The frequency 
  of the VHF beacon is 145.825 MHz, mode FM.  For more information see:

Al Ward, W5LUA, of Allen, Texas, is the first person to achieve the
ARRL's Worked All States (WAS) on 1296 MHz, making him 1296 MHz WAS #1.
Ward first started on his pursuit January 25, 1977, with his first 1296
MHz contact with Leroy May, W5HN (SK). His 30 year quest ended last
week, with confirmed contacts with Wyoming, Utah and Idaho, giving Ward
his last three needed states, thanks to Paul Perryman's, WA5WCP, EME
DXpedition. 

"I couldn't have done this without Paul," Ward said. "Also, thanks to
Ron Roche, K0ALL, and Barry Malowanchuk, VE4MA, in North Dakota for
number 47 in August. Without them, it just wouldn't have been possible."
After collecting his 50th QSL card, Ward drove from his home in Texas to
Little Rock, Arkansas so ARRL President Joel Harrison, W5ZN, could
verify his cards and complete his WAS paperwork. "Verifying QSL cards
from 30 years of activity brought back a lot of memories of several
stations active on 1296, many who are Silent Keys now," Harrison said.

1. Successful Contact with Gail Borden Public Library

Youth from Elgin, Illinois experienced an ARISS contact on Wednesday, 
September 5. Astronaut Clay Anderson, KD5PLA, fielded 20 questions put 
to him by 16 children visiting the Gail Borden Public Library. The 
contact was held in conjunction with the multi-media educational exhibit
 "SPACE: Dare to Dream." Approximately 100 people witnessed the contact,
 including the mayor of Elgin and three city council members. Two admin-
istrators from School District U-46 attended, as did reporters from the 
Daily Herald and Elgin Courier newspapers. Children were interviewed 
pre-contact by WGN Radio and the event was reported on by WBBM News 
Radio 780 in Chicago. Video was also streamed over the internet. 
The audio from this event was fed into the EchoLink AMSAT (101 377) 
and JK1ZRW (277 208) servers, and received 16 connections from 6
countries 
and 3 repeater nodes. Five connections were also made to the
IRLP Dis- covery Reflector 9010.  The Courier News ran an article
covering the 
event:

2. Successful Contact with M. L. King Academy

An ARISS contact was completed with the M. L. King Academy (formerly 
Alexander Macomb Academy) in Mount Clemens, Michigan on Wednesday, 
September 12. The academy is a Title 1 school located in a suburb of 
Detroit and has a population of approximately 66% African American and 
30% Caucasian students. Nearly 80% of the students and their families 
are economically disadvantaged. Students in grades K- 6 will study space
 and the history of spaceflight. They will participate in related hands 
on activities and will use several resources available on the NASA 
education website. As a result of their space science research, lower 
grades will create posters and upper grades will produce Power Point 
presentations. All students will be able to witness the contact through 
the school's television equipment.


3. Successful Contact with Westbrook Intermediate School

An ARISS event with Westbrook Intermediate School in Clear Creek, Texas 
took place on Friday, September 14 via the telebridge station W6SRJ in 
California. Westbrook is a gifted and talented (GT) magnet school with 
a program known as Webster Academy - Visions in Education (WAVE), which 
started at Webster Academy in 1996. This GT magnet brings together over 
500 gifted and talented students from across the district to participate
 in a unique program design.  One of the opportunities available to WAVE
 students is an amateur radio license class.  In partnership with the 
Clear Lake Amateur Radio Club, over 300 students have earned their ham 
radio license over the last 8 years. At any time, there are
approximately 
100 hams in attendance at the school. Students and
teachers have discussed 
the ARISS contact in their classes, and all
students have participated 
in the development of questions for Clay
Anderson. 


4. Upcoming School Contacts

Mitchell Elementary School, a NASA Explorer School (NES), in Ann Arbor, 
Michigan has been slated for an ARISS contact. The event is planned for 
Monday, September 17 at 13:39 UTC.  The use of Amateur Radio provides
for 
the integration of technology, math, science, geography, writing,
reading, 
and speaking through hands on applications of these concepts.
Amateur radio 
operators in Ann Arbor will present talks and
demonstrations covering these 
concepts prior to the actual contact with
the ISS. Through this experience, 
students will gain an understanding
of amateur radio technology and it's 
potential. Students will visit
websites to view and listen to previous 
conversations with the
astronauts. Mitchell Elementary will download and 
install tracking
software onto the school lab computers to follow the space 
station as
it passes by on the day of the contact.  Using computer software,

students will write essays explaining why they should be chosen to fly
on 
the ISS. Local, state and federal officials will be invited to
attend the 
event. Television, radio, newspapers, and the internet will
cover the 
contact. The audio from this event will be fed into the
EchoLink AMSAT 
(101 377) and JK1ZRW (277 208) servers, and into the
IRLP Discovery 
Reflector 9010. 

Pueblo Magnet High School in Tucson, Arizona plans to participate in an 
ARISS contact on Friday, September 21 at 15:04 UTC.  The school formed
an 
Amateur Radio Club last year to involve students in math and
science. Dona- tions of radio equipment were made by the local Catalina
and Green Valley 
Amateur Radio Clubs.  Five students have already
earned their Technician 
licenses and one has upgraded to General Class.
Science, art, and the 
economic departments are involved in this
endeavor; the Special Education 
department has also been included -
some students who will participate in 
this event are autistic. Eighty
percent of the students come from econom- ically disadvantaged families.
Local and national media coverage is anti- cipated. The audio from this
event will be fed into the EchoLink AMSAT 
(101 377) and JK1ZRW (277
208) servers, and into the IRLP Discovery 
Reflector 9010.
