>From AMSAT HQ SILVER SPRING, MD.
December 21, 2008
To All RADIO AMATEURS
BID: $ANS-356.01

Happy Holidays!  Best wishes to everyone during this festive 
time of the year.  As I write this, a major snowstorm is pro-
viding plenty of 'white stuff' in the Midwest and New England, 
so I presume this means that we will have a white Christmas 
here in Massachusetts.  While this is certainly a time of 
economic uncertainty, I also know that our members continue 
to make a difference for AMSAT.

A number of interesting opportunities and events have developed 
over the past two months for AMSAT that I would like to briefly 
share with you:

1.  ARISS Silver Anniversary.  The first amateur radio two-way 
communication between the Space Shuttle and amateurs on the 
ground took place on December 3, 1983 when Owen Garriott, W5LFL 
made his historic flight on STS-9.  There are a number of oppor-
tunities for amateurs to help celebrate this event and the ARISS 
International Committee, chaired by AMSAT VP-Human Space Flight, 
Frank Bauer, KA3HDO have arranged for some special events.  Please 
check ANS and the AMSAT webpage (www.amsat.org) for the latest 
information and join the fun!

2. AO-16 operations.  As expected, performance of this spacecraft 
is declining as the spacecraft's temperature is dropping due to 
longer eclipses resulting in less sunlight and a cooler spacecraft.  
This drop in temperature is causing the satellite's hardware timer 
to reset until the spacecraft warms up (when there is at least 85%  
illumination).  If you're interested in making two-way contacts 
using AO-16's unique  cross mode, cross band voice repeater, with 
an uplink on 145.920 FM and  downlink on 437.026 MHz reduced carrier 
AM, now is the time to try it!  The satellite is expected to 'go 
silent' shortly when temperatures stay low enough as to not allow 
software configuration of the satellite before the hardware timer 
resets itself again.

3. President's Club.  A fundraising appeal letter was mailed this 
week to all AMSAT members.  Please consider donating to the AMSAT 
President's Club so that we can continue our efforts to maintain 
amateur radio in space.

4.  Near Term Engineering Task Force.   I announced at the AMSAT 
Annual Meeting in Atlanta that a group led by Bill Ress, N6GHZ 
had been formed to review the 'Rideshare' Proposal developed by 
Tom Clark, K3IO as well as evaluate AMSAT's ability to develop a 
modularization strategy to adapt RF packages to various structures.  
The committee has been diligently meeting every two weeks via tele-
conference to discuss future options for AMSAT and to help structure 
AMSAT's thinking on future spacecraft opportunities.  While it is 
too soon for formal announcements of their findings, it is good to 
know that we have a formal group actively focused on engineering 
issues.

5.  SuitSat-2.  Development work continues to place SuitSat-2 in 
service sometime in 2009.  Several engineering issues have recently 
surfaced regarding modulation and transmission schemes and the team 
is evaluating several options regarding how best to resolve the issues.  
Several individuals have recently joined the engineering team to help 
overcome these challenges by developing potential alternative solutions.  

6. ITAR.  I announced at the AMSAT Annual Meeting in Atlanta that AMSAT 
would actively develop a strategy concerning ITAR (International Traffic 
in Arms Regulations) and related export regulations.  Our goal is to 
ensure that AMSAT is in full compliance with ITAR, develop materials to 
train our satellite builders on ITAR compliance,  and to seek ways 
where we may continue to work with other AMSAT organizations on satel-
lite projects.  Since the Annual Meeting, Bill Ress, N6GHZ and I have 
been working with an attorney who specializes in ITAR.  We hope to make 
a formal submission to the State Department regarding ITAR in early 2009.

7. AMSAT Lab.  AMSAT is actively seeking a new home for our AMSAT Lab.  
Unfortunately, due to changes that took place at HISS (Hawk Institute 
for Space Sciences) in Pocomoke City, MD over the summer, we are forced 
to remove our equipment and clean room from the current facility.  We 
are in active discussions with several institutions concerning potential 
relocation, but no decision has been made.  If you are in position to 
provide contacts with a not-for-profit institution that might be inter-
ested the hosting the AMSAT Lab, please contact me.  

8.  AMSAT 40th Anniversary.  AMSAT was incorporated in 1969, so this 
coming year (2009) is our 40th Anniversary!  The 2009 AMSAT Symposium 
will take place the weekend of October 9 in the Washington-Baltimore 
area. Look for details in the upcoming AMSAT Journal.  Please join us 
that weekend as we celebrate a significant milestone for AMSAT and 
build the foundation for the next 40 years of AMSAT.

As you can see, there are a number of activities that are ongoing within 
AMSAT.  While we are challenged by the impact of current events, we con-
tinue to move forward in a number of areas.

As always, I appreciate hearing from the AMSAT membership.  Should you 
have any questions or concerns about AMSAT, please don't hesitate to 
contact me.   I will make every effort to respond to e-mails that I 
receive, but please keep in mind that I travel extensively which may 
limit my ability to respond quickly. Please know that I read every e-mail 
that I receive from AMSAT members and that I appreciate every person's 
willingness and time spent to share their thoughts and suggestions.

Seasons Greetings,

Barry Baines, WD4ASW
President-AMSAT

ARISS 25th Anniversary Adds New Modes

[ans]  ANS-356 AMSAT News Service Weekly Bulletin
AMSAT News Service Bulletin 356.02

>From AMSAT HQ SILVER SPRING, MD.
December 21, 2008

BID: $ANS-356.02

ARISS International Chairman and AMSAT-NA V.P. for Human Spaceflight 
Programs Frank Bauer, KA3HDO invites amateur radio operators around
the world to join in the ARISS team's 25th anniversary of amateur
radio operations from space.  Increased activity and new exciting
modes of operation from the ARISS amateur radio station aboard the
International Space Station are featured in this celebration operating
period.

To date, the ISS crew has configured the radio to support cross-band
repeater operations, they have supported some SSTV downlinks and we 
have had the opporunity to participate in a special test of 9600 baud 
packet radio operations on the simplex frequency of 145.825 MHz. This
past week featured 1200 baud packet operations on 145.825 MHz to open
a dual-hop APRS path in case PCSAT-1 became operational. 

For the upcoming weeks the following is being planned in the 
near-term:

+ December 21-26 - we plan to support the Crossband repeater mode 
  with a twist. Our intent is to configure the radio for 145.99 MHz 
  uplink including PL tone of 67.0 and 437.80 MHz down. This will 
  be performed in low power mode.

+ December 22 - Expedition 18 Commander Mike Fincke and Flight 
  Engineer Yury Lonchakov plan to perform a spacewalk. As per 
  standard procedure, the ISS ham radio system will be turned off 
  for the EVA.

+ December 28-January 3 -  we plan to reconfigure the Crossband 
  repeater for a special experiment. This will be a test of our 
  L-Band uplink capability, which, to date, has not been proven 
  out. Plan for an uplink of 1269.65 MHz and and downlink on the 
  standard frequency 145.80 MHz using low power. Given the subtan-
  tial cable losses of the L-band system, we hope some "big guns" 
  are able to penetrate through, keep up with doppler, and make 
  the connection.

+ And at times, especially during the weekends, you might see some 
  SSTV operations if the crew is available.

The ARISS team will provide more updates in the near future. They 
would like to remind everyone that ISS flight requirements related 
to EVA and vehicle activity may require the radio to be off for some 
portion of this schedule. And school contacts and general QSO oppor-
tunities by the crew will also preempt this schedule for short periods 
of time. (But remember that if you hear these, you still qualify for 
a commemorative certificate).

Details of how to receive your ARISS 25th Anniversary Commemorative 
Certificate can be found at http://www.amsat.org.

ARISS US Hardware Manager Lou McFadin, W5DID provided a summary of
expected parameters for those considering trying to make a contact 
with the ISS on L-band to VHF crossband repeater experiment planned
for December 28 to January 3.

Lou reported, "The measured sensitivity of the L band receiver on 
a D700, as the radio aboard the ISS, is -105dBm for full quieting. 
The cable loss from the radio to the antenna is 9.3db. The antenna 
gain is zero db. The polarization is LHCP." 

Extending the calcuations to cover the entire system path, Lou said,
"The path loss at the horizon on L band is -160dB. That means the 
required EIRP for a full quieting contact at the horizon is 65dBm. 
The path loss decreases by 15dB at 80 degrees elevation so that means 
you can get full quieting with 50dBm in that case. To further elaborate 
if you use a 20dB gain antenna (a small dish), it is estimated that
you can complete a QSO with 32 watts at the horizon or 1 watt at 80 
degrees elevation."

The planned operating frequencies include:
Uplink:   1269.650 MHz FM
Downlink:  145.800 MHz FM

AMSAT-NA VP Operations, Drew KO4MA reported on behalf of the AO-51
Operations Team, "We are now back to the normal uplink arrangement
of 145.920 and 435.300 for normal repeater use.  We changed from the
QRM mitigation experiment of operating via the 145.880 uplink back to
this normal mode to enable low-power repeater QRP operation.  The 
QRP repeater is now operational on 145.880 and 435.150."

As a result of the QRM investigation Drew said, "I'm convinced not 
all of our problems are related to the cordless phones. I heard tonight 
whistlers, blowing in the mike, and folks giving extended CQs. We are 
working on finding the general location of the cordless phones, but 
it takes time. Then we'll work at shutting them down.

The AO-51 Operations Team provided results of their QRM investigation
on and around the 145.920 uplink. There may be some low level modula-
tion on some of the signals in the captured waterfall diagram. It is 
believed they may be from some of the same long distance phones that 
were plauging AO-27 and SO-50 a few years ago. Observations indicate 
the interfering signals are lost about the time the edge of the foot-
print crosses the mid Atlantic states. Refer to this page:

PCSAT-1 Recovery Partial Success

Bob, WB4APR provided an update on PCSAT-1 recovery status from the 
U.S. Naval Academy Satellite Laboratory.  Bob wrote, "For the first 
time in 7 years, we were not able to fully recover PCSAT during this 
full sun period despite the efforts of a number of dedicated volun-
teers around the world."

PCSAT-1 is only operation when its solar panels are illuminated by
sunlight.  Full sun periods occur when passes are at sunrise and 
sunset to earth observers.  PCSAT gets sun 24 hours a day then, but 
only on the side panels due to the orientation of the satellite. 
Ground station controllers were able to recover PCSAT-1 and the weak 
solar illumination allowed operation for generally an orbit before
the power budget could not support the load.

Bob summarized, "Anyway, this is not the last you will hear of PCSAT,
but there will probably not be any more several week full sun, full 
recovery periods as there have been in the past. I really appreciate 
all the efforts of so many operators. So play packet on the ISS and 
thanks again for all your efforts!"

In addition to regular membership, AMSAT offers membership in the
President's Club. Members of the President's Club, as sustaining donors
to AMSAT Project Funds, will be eligible to receive additional benefits.
Application forms are available from the AMSAT Office. With that do recall

He acquired his size from too much pi.
