Pete
Your confusion is completely understandable and I will do the best I am
allowed and able to do to explain.
First, my apologies to everyone for the necessary low profile on P3E.
The agreement announced was "We get P3E if I get a launch".
That is as far as I AM ALLOWED TO GO.
I am requesting from the US government a way, a path forward, that puts
something they want tested into P3E and in return, they give us and our
amateur satellite service payload a ride DIRECTLY to the final orbit, no
motor required.
The branch of the US government being worked with is VERY averse to
publicity. Thus, radio silence.
Peter and AMSAT-DL were told by me: " Should you say yes and give to me the
future might very well be: We have secured the launch, and oh, by the way
it was launched yesterday and the orbital elements are.....".
Secrecy and a guarantee of that's REQUIRED to work with the US government
on many occasions.
The USG is studying and is SO FAR positively considering the Phase 3E
proposal. I'm sure you've seen that only in the last month has the bloody
congress of the US and the president of the US have passed and signed a NEW
BUDGET. Since this is a NEW INITIATIVE it must come from a new budget since
it was NOT ALLOWED on a continuing resolution.
--------------------
On Phase 4 B, there are two entirely separate activities underway and while
they can work together, only one needs the other.
AMSAT raised a large pot of money and VT and AMSAT used it to pay for a
study to convince the USAF that we would be good citizens if they carried
our little payload in their huge spacecraft. That study will be completed
in January. Only then will we know that we even HAVE a mission.
Separate from AMSAT, VT and Mike Parker KT7D and Rincon Research, Inc, the
company he founded have undertaken the technical development of the
spacecraft payload COMPLETELY AT RISK because we don't know the payload can
accommodate us. That is what the study is for.
Neither Virginia a Tech nor Rincon people are volunteers. They must be
paid. We have decided that AMSAT has small chance of raising the millions
it will take to do this mission, so it is now A VT MISSION with help from
AMSAT and based on a major donation of flight hsrdware and software from
Rincon.
Only in the month of December did I find a couple of hams who were willing
to risk enough money to allow us to do the technical work even though all
of the AMSAT money, the Rincon money and the donations VT has received
might go for nothing.
All involved think the upside potential is so huge, the risk is worth
taking.
In parallel to the spacecraft payload effort, done under the cloak of ITAR,
is another effort done out in the open and free from ITAR is an effort to
design a inexpensive ground terminal for amateurs that would cost tens of
thousands of dollars commercially for as much under $1000 as we can get it.
We benefit from being completely open source, open specification, and
totally free from ITAR on this ground terminal. Furthermore, since it is
software defined radio, it is easily reprogrammed to do many different
kinds of missions just be changing the software.
The ground terminal effort has received generous donation of hsrdware for
development of the system quickly from Ettus Research. AMSAT-NA wants to
attempt to use the terminal for current and future projects so the VPE,
Jerry Buxton, invested in a copy for use in Texas by antenna and other
developers for both spacecraft and ground terminal pieces.
At Virginia Tech I have four students, two members of technical staff, two
research faculty and our newly minted adjunct professor Tom Clark K3IO all
now SUPPORTED to do the work but this happened IN THE WEEK JUST BEFORE
CHRISTMAS.
Michelle Thompson, W5NYV is leading the development of ground terminal FOR
PHASE4B and has volunteered to help AMSAT with ground terminal for any
projects Jerry wants to have AMSAT consider.
If the payload accommodation study is successful, and if we get our payload
ready and if we raise millions NOT FROM AMSAT SOURCES Phase 4B will go in
late 2018 or early 2019.
Finally, I am director of a research center at Virginia that has over 100
students, research staff, and affiliated faculty. I started both of these
initiatives but I have huge responsibilities and I've needed to raise money
to pay for those to whom I'm now delegating lots of this work.
Doing all this and running the research center (the second largest at
Virginia Tech), has been more than a full time job. AMSAT had been consumed
with Fox1A, -Cliff, and -D which they committed to BEFORE these
opportunities arose. AMSAT is undergoing a true resurgence inside and this
will translate into a major rebirth of the organization.
As a newly minted director of AMSAT, speaking only for myself, I appreciate
your enthusiasm for wanting these projects and in impatient as heck to get
them up. As director of AMSAT I know I can't waive a magic wand and make
them happen. It will take thousands of volunteer hours and your financial
support and your cheerleading and advocacy to get them up.
As director of research of Hume Center of Virginia Tech, it will take
millions of dollars and dedicated paid engineers and project management
(professional) to work with the US government to accomplish these goals.
Finally, we are busting our hump to get things done, and we all want them
desperately and your positive encouragement is something we all seek.
73s and may 2016 be as awesome as it can be,
Bob

Robert,
Thank you SO MUCH for taking the time and providing these detailed
explanations. I trust that many in the amateur satellite community will
find them very useful. If I don't fully appreciate the security
implications, from what you say I can at least understand the need for
confidentiality, so, again, thanks very much for informing us.
My only afterthought is that, if such information was posted, for instance,
on the AMSAT newsfeed, a lot of confusion and misunderstanding would have
been avoided.
Personally, I fervently hope that the "P3E deal" will see the light of the
day, and, yes, that the SDR transponder on board will also provide for that
"analog experience" which is so dear to many of us.
73 and HNY

Message-ID: <001501d140be$9c647c10$d52d7430$@xxxxxxx.xx>
Content-Type: text/plain; charset="us-ascii"
APRS question:
I am using AGWUIDigi to Igate the 145.825 data from ISS, NO-84, etc.
How do I avoid that when a local HAM uplinks to ISS, I hear his
uplink, I Igate his uplink, and then when ISS digipeats, that is seen
as a dupe ?
Result would be that that local HAM would never show up anywhere as
heard via ISS or NO-84, as I would have Igated his uplink 2 seconds
prior to the digipeat.
Setting the APRS server logon filter to exclude his CALLSIGN, would
that block just incoming or also outgoing (RF to Internet) packets ?
If so, I could use such a filter: -b/CALLSIGN
Would this be the way to solve this ?

All:
Having failed to copy ANY 9600 baud satellites with my Kenwood TS-2000
and 9600 baud SCS modem, I decided to try a Funcube Dongle instead.
Needless to say, the Funcube worked and I was able to copy XW-2F's down
link using UZ7HO's 9600 baud G3RUH Soundmodem.
That made me take a closer look at the Kenwood TS-2000 / SCS Modem setup
and, low and behold, I found that the data rate for the external TNC was
set at 1200 baud instead of 9600. For those TS-2000 users, this setting
is found in Menu item 50F.
I'm hoping this is the only setup parameter I missed. I don't know of
any 9600 baud terrestrial links or PBBS near my location so I'll have to
wait till the next 9600 bird comes along.

Hi!
Thanks for the responses to my request last night for stations to send me
information on the grids that they activated during calendar year 2015! I
have received information from 18 different stations, and a couple of
others have said they will compile their lists after 31 December. This is
great, and I appreciate the responses. I would like to hear from any
satellite operators in Mexico that have been active from more than their
home grids, as I know I have worked a few down there in different locations
during 2015. I would appreciate receiving this information by 15 January
2016, if others are interested in providing me their lists of grids
activated in 2015. I also have details on a couple of other stations that
have posted their lists of grids activated in 2015 online, and I will
include those in my writeup.
I received one comment that questioned my use of Twitter in my request for
this information. I understand that many hams don't use, or care for,
social media platforms like Twitter. Of the 18 stations that have sent me
information, about 2/3 of them are also on Twitter - and all of those have
operated from between 5 and 58 different grids in 2015. Many of us use
Twitter specifically, since it does not require full access to the Internet
to send information for others to see. Twitter can be used with SMS
messages, which means just having access to a mobile phone network is all
that is needed to interact with Twitter. Many of us also keep our Twitter
feeds open for anyone to read - the reason why I usually refer to a link to
see my @xxxxxx Twitter feed in a web browser (http://twitter.com/WD9EWK ),
without having a Twitter account. Twitter is just another way to spread the
word, a reason why I also posted my original request here on the AMSAT-BB
list last night.
If I was interested in plotting a map showing all of the grids that were
active in 2015, this could be done by everyone submitting lists of grids
worked during the year. Although that would make for a nice map, especially
to see if it would have been possible to work all of the states in the
continental USA during the year, that is a larger project I didn't want to
take on. I'm looking to highlight those stations that go out and activate
grids away from home, for the benefit of other satellite operators.
Thanks again, and 73!

PSAT should respond to the path of ARISS or APRSAT in its current
configuration.

Hi All,
Just as a reminder, we will start our second activation today, Monday 28th
until Thursday 31st.
The first activation has shown us that the uplink frequency seems to be off
by +12kHz, so please adjust your uplink frequencies accordingly. We are
also seeing that activating the transponder makes the satellite power
negative, meaning the solar arrays can not generate enough power to keep
the transponder running permanently. This is not unexpected as the
satellite is operating in a different mode than originally anticipated
during the design phase.
We are discussing various ways to solve this, including multiple ways of
scheduling the transponder operations. With these discussions ongoing we
would still like to try the second activation and obtain some more data
about the system. We will activate the transponder for as much time as the
power budget allows, but please be aware that you may find the transponder
to be off while the batteries recharge.

Hi Tom,
I have a GPS locked 10 GHz beacon on Mt Mansfield here in Vermont and I
use the exact setup to monitor it.
I use an old DSS dish and a $7 LNB plus a FunCube. IF frequency is about
617 MHz for the 10,368.320 beacon.
I just looked on eBay and the LNB I use is there for $6.95 plus free
shipping.
Mike
