Hi Gordon,
such a fuse would not prevent a battery from an internal short-cut in
one or more cells... that's in fact what happened to AO-40.
Also you have to make such a "failsafe" feature really fail safe, so
that it does not hit you in the back if it fails..
These kind of things, like Watchdogs, always sound simple and easy, but
very often they are cause for more trouble.
We have seen satellites with Watchdogs going mad and resetting computers
while it was not necessary and do more harm than good.
Clearly, nobody expected that the battery would die so quickly,
otherwise some actions would have been done before...

Hey everyone,
Patrick asked me to post the following, for any of you who need DM52 and/or
New Mexico on the satellites.
He will work the following passes:
AO-27 at 2235 UTC from DM52 on the New Mexico-Arizona border.
AO-51 at 2318 UTC from DM52 entirely inside New Mexico.
AO51 at 0054 UTC from DM52 on the New Mexico-Arizona border.
He'll be in Hidalgo County, New Mexico for all three passes, and on it's
border with Cochise County, Arizona, for the two state-line passes.
73 to all,
Tim - N3TL

Digital signal processing is 40 year old technology at DARPA and first
appeared on the amateur radio scene 20 years ago. We certainly don't want
AMSAT to ignore this technology as it can reduce hardware complexity, size
and power requirements and therefore decrease costs and increase
reliability.

Hey everyone,
For those of you who didn't hear the pass, the ability to reach AO-51
vaporized about 2/3 through this last orbit up North America from the south,
thanks to a carrier or some kind of interference stronger than I have ever
heard. Whatever captured the satellite's uplink wiped out every signal
trying to reach the satellite, based on what I heard from EM84.
I would direct this message to the control team and not post it to the BB if
I believed for one second that what resulted in complete jamming of the
satellite was not intentional and malicious.
I believe that it was.

AMSAT Says "We're Going Back to Space"
AMSAT News Service Bulletin 291.01
>From AMSAT HQ SILVER SPRING, MD.
October 18, 2009
To All RADIO AMATEURS
BID: $ANS-291.01
The Board of Directors has adopted the Engineering Task Force
recommendation that low-cost launch options be immediately pursued.
The AMSAT engineering team will develop a 1U CubeSat design effective
immediately. Tony Monteiro, AA2TX, Vice-President of Engineering said,
"We are recommending an approach that gets AMSAT back up in space with
new satellites by leveraging the skills and technology we have today."
The new AMSAT CubeSat's initial capability is planned to add to the
popular low-earth orbit FM transponder fleet allowing hams to continue
to use their existing handheld and portable antenna systems. This also
allows an accessible entry path for new satellite operators to get
started. The existing FM satellites are starting to show their age.
The flight version of ARISSat-1 has been developed to fit into the
CubeSat model. AMSAT's flexible Software Defined Transponder (SDX),
simplified IHU, power control subsystem, external interfaces to ex-
perimental payloads and cameras will now allow a modular approach to
mission design using proven subsystems and components. The ARISSat-1
mission planned in 2010 will be the initial flight test of AMSAT's
modular satellite.
Here are some of the highlights ...
+ AMSAT will develop comparable AO-51 level of performance packaged
into a 1U CubeSat. This includes a U-V transponder, V telemetry,
U command receiver, IHU, power control. This can be done with our
modular design.
+ This will be a U/V FM Transponder, not done before in a 1U CubeSat,
which can be worked with a HT and a simple antenna. CubeSat power
limitations are planned to be addressed through research and devel-
opment of deployable solar-cells.
+ AMSAT will make our open-design satellite modules and technology
available for other satellite teams to build into their missions.
+ This new approach will provide a reliable radio link for future
CubeSats allowing university teams to concentrate on their scientific
objectives.
+ The modular nature of the AMSAT CubeSat system will allow add-on
missions utilizing several different types of modulation and band-
width. These can be pursued with future low-cost CubeSat launch
opportunities.

AMSAT, IBM, SUNY-Binghamton Announce NextGen CubeSat Development
AMSAT News Service Bulletin 291.02
>From AMSAT HQ SILVER SPRING, MD.
October 18, 2009
To All RADIO AMATEURS
BID: $ANS-291.02
AMSAT will work with a university student engineering team to
develop the NextGen Cubesat.
NextGen Program Manager, Alex Harvilchuck, N3NP introduced this new
program at the AMSAT Symposium. Alex revealed program goals and its
initial plans with a paper in the Proceedings and presentations to
the AMSAT Board of Directors and to the attendees during Symposium
sessions.
NextGen consists of AMSAT volunteer mentors working with IBM Global
Services Systems Engineering Division, and SUNY-Binghamton (also
called University of Binghamton) senior level engineering students
participating in their 'capstone' engineering project.
Alex summarized the NexGen program goals:
+ Intial analysis of ARISSat-1, documenting the systems, and analysis
of the lessons learned from ARISSat-1 and other prior spacecraft to
create a building block architecture for future satellites.
+ Open, modular, evolutionary, and documented design based on this
analysis.
+ Redesigning the ARISSat-1 Power Systems into a next generation power
system using supercapacitors instead of batteries and reducing the
footprint of some of the boards.
+ Analysis and modification to the structure to incorporate deployable
solar panels with a scalable design that will work for 1U, 2U and 3U
sizes.
+ Design a Picosat-class bus structure that AMSAT, or any other Univer-
sity, can use for 1U, 2U, or 3U CubeSat spacecraft. AMSAT could make
the open design available at low-to-no-cost to qualified University
groups.
+ An Engineering Model of the NextGen CubeSat spacecraft bus will be
on display at the Dayton Hamvention AMSAT Booth for everyone to
study.
Alex summarized, "Starting with our initial core team of 34 students,
plus advisers, mentors and volunteers at Binghamton University this
will be an ongoing effort. It is not a one time event, but the start
of a stable, evolutionary design process that will further STEM (Sci-
ence, Technology, Engineering & Mathematics) with the Next Generation
of engineers and amateur radio operators. We are looking for other
individuals and University/School teams to participate in all aspects
of the spacecraft design - RF Systems - Guidance, Navigation, Control
& Experiment Systems - Power & Structure Systems."
Volunteer mentors are needed! Even if you only have an hour a week,
you can mentor a student over the phone or you can peer review a
document that the students are working on. If you have more than an
hour a week, you can implement a small design change to an existing
subsystem; you could respin the board layout to meet a reduced form
factor; you could redesign a module to use different technology.
Contact Alex via e-mail at amsat@xxxxxx.xxx .
AMSAT's Board of Directors has approved the support of the University
of Binghamton NextGen Cubesat Proposal and agreed to provide $1,200.00
in immediate funding to the Binghamton Foundation to support student
expenses and initially budgeted $10,000.00 to cover material costs
associated with hardware development between September 2009 and May
2010. The Board will review progress at the end of the first semester.

Discussions Continue For New AMSAT Lab Site
AMSAT News Service Bulletin 291.03
>From AMSAT HQ SILVER SPRING, MD.
October 18, 2009
To All RADIO AMATEURS
BID: $ANS-291.03
AMSAT President, Barry Baines, WD4ASW discussed an opportunity under
serious discussions with the University of Florida, Gainesville to
locate AMSAT's satellite laboratory on campus.
Among discussions over the past 12 months, AMSAT has had conversa-
tions with several universities concerning a potential relationship.
This opportunity arose out of an amateur radio talk given at The
Villages ARC by Dave, AA4KN and Drew, KO4MA in April. This lead to
contact with UF's Dr. Norman Fitz-Coy. A Memorandum of Understanding
has been drafted and is currently under review by legal teams. At
this time there is no timeframe for bringing about a formal conclusion
as the MOU discussions continue and internal UF approval still needed.
Relocating the AMSAT Lab from the 'Eastern Shore' to 'The Swamp'
offers significant potential:
+ Location on a major university campus in a state-of-the-art building
+ Integrated into a facility focused on small satellite development
with clean room installation at the host's expense (not AMSAT)
+ Potential for student projects focused on AMSAT needs
+ Broadening of AMSAT's presence in the wider university community
+ Potential research/development opportunities for AMSAT and AMSAT
members
+ Establishing a program that offers significant traction for
education outreach

October 18, 2009
To All RADIO AMATEURS
BID: $ANS-291.04
Amateur Radio Newsline #1678 reported that Industry Canada has
informed Radio Amateurs of Canada that it has authorized the
Department of National Defense to use a digital system called
Enhanced Position Location Reporting System or EPLRS in the
430 to 450 MHz shared 70 centimeter band. The EPLRS system
consists of mobile, fixed, transportable and airborne stations
that use 5 MHz-wide spread spectrum channels to provide strategic
telemetry information for military platforms.
This authorization is on a no-protection, non-interference basis,
which means that no new restrictions will be imposed on Canadian
amateur operations in this band as a result. Industry Canada says
that there is a slight chance of minor interference to amateur radio
systems. Typically in the form of a minor audible clicking noise. If
Canadian amateurs encounter such interference, they are requested to
report it by e-mail to Radio Amateurs of Canada at regulatory at
rac dot ca. The information reported should include the geographical
location, date, time, frequency and mode being used by the amateur
station, and a description of theinterference.

John, I dont know what happen, but I didnt hear a thing on the AO-27 pass
that was East of me. Checked the pass data on SatPc32 and made sure I was on
the right freq's, but didnt hear a thing, so was a complete bust for that
Grid. I even had an audience, and sure felt like an idiot after building up
the excitement, and then zilch. Oh well.... I guess it happens. Even the
SO-50 pass that I talked to Patrick was very noisy, and that is probably due
to all the intermod in the area I was in, not only from the commercial
stations, but from hams walking around keying up their mikes, talking to no
one, just kerchunking the 440 repeaters.
Very thick and heavy fog this morning going to Fresno, with visibility down
to 100 feet in some spots, and then most of the day overcast, hot and humid,
which is rare here. There is an unusual High over us, causing this very
early fog season. Felt like I was back in Alabama and Mississippi on my road
trip...
Unknown when I'll get back up that way......not for a month or more I am
sure, but I'll hope for an AO-51 pass instead. Sorry it didnt work out..

Patrick reported hearing you in the morning from
DM06 but didn't hear you on any other pass. Hope
everything is ok there.
The AO-27 pass was a zoo but Doug and I both made
a contact with WA8SME.
Let me know if you plan to operate from DM07 in the
future. Thanks.

Geeeeze, now I know why DN00 and 01 are rare grids! There literally isn't
anything out there, certainly no local RFI or traffic. It took 7 hours of
driving round trip for 7 minutes of satellite time.hum 60 to 1, guess that
ain't bad. Anyway, thanks to all who stuck it out through some QRM and
congestion to make contact. Simply confirm the contact via e-mail and your
cards will be in the mail, no SASE or QSLs required on this end.

Hi Tim
Your post reminded me of a time long ago.
I understand FM and Discriminator capture versus side band.
It was on AO-13 with a group chatting when all of a sudden there was a
very strong signal that
done the same thing to a linear transponder as a strong CW on freq would
do to FM.
As soon as the strong signal cease we attempted to get to the bottom of
the issue.
It took 15 minutes or so when we found we had a Russian EME station on
our hands trying satellite for the first time.
After much attenuation we all had a nice chat.
I never heard that lad after that so I do not know what his summation of
his efforts were.

There are all sorts of reasons why flying digital transponders is a
good idea. Your cell phone (presuming you have one) uses digital
technology to improve battery life, range, and to provide a variety of
other services, including digital data, and the same benefits could be
harnessed aboard amateur satellites. The desire to do so isn't just
for technology's sake: it is to enable a wide variety of new
capabilities that can't be achieved with conventional analog systems.
I understand the desire for being "conservative", but there is a
different from being conservative and simply ignoring the
revolutionary trends in communication that are enabling revolutions in
phone, data and voip services.

Hello
I have reactivated this project.?? I have finished a sequencer by W6PQL.?
With a handfull of various relays I will be connecting everything together.?
Before the last "smoke test" I would like to hear from anyone who has done
this project before (910's aren't cheap).? I would like to know how you
connected everything PTT for 910, amp, relay timing etc.? Anything else you
can think of.? On satellite uplink at 1268.7Mhz we don't care about
receiving.? However around W. Wa. there is some 1296 activity which is fun
to play with.? Antennas are either a 16 turn helix or two stacked 24 element
loop yagis.
