AMSAT-NA 2016 Symposium at Sea
Get ready to set sail for the 2016 AMSAT Space Symposium and Annual
Meeting ? at sea! With only a few months between now and our sailing
date of November 10, cabins are starting to fill up quickly. If you
have not made reservations, please consider doing so to ensure your
cabin preference may be accommodated. While our AMSAT group
reservation has a negotiated rate for category 4B inside cabins, many
group members have opted to reserve ocean view and balcony cabins.
IMPORTANT NOTES:
- Booking your Carnival Cruise does not register you for the
AMSAT Symposium. There is a charge for each Symposium attendee of
$40. This fee applies to those who will attend the technical
presentations only and includes a copy of the printed Proceedings.
Additional guests are entitled to attend all other events. The
registration form is available from the AMSAT office or store website.
- The AMSAT 2016 Space Symposium Cruise flyer included in the
2016 Board of Directors ballot mailing lists an incorrect group
booking code. The correct AMSAT group code is 8Z0FR5.
- Ground transportation options have been added to the FAQ
page on the AMSAT Symposium web page. Carnival offers round-trip
transportation from HOU airport to the cruise terminal at
approximately $74 per person, IAH airport $94 per person.

70cm Satellite WebSDR Operational in the Netherlands
Fontys University Eindhoven, Netherlands, has opened their PI5FTS WebSDR to
the amateur radio community. This site will receive the 70cm amateur
satellite
band:
http://vhf.pi5fts.nl/
You need both Java and JavaScript enabled for this page to work properly.
If you don't hear anything, probably Java is disabled or its version is too
old (i.e., pre-1.4.2). A web chat feature for the SDR users is also included
on the site.

LibreCube CubeSat Open Standard Draft Open for Review and Comment
The LibreCube standard project is engaged in the endeavor to write
on a handbook that surveys openly available space standards (mostly
ECSS and CCSDS) for potential application in CubeSat missions.
In a message posted to the cubesat.org list, Artur Scholz announced
that the draft of this handbook is now ready for review. It mainly
consists of two parts:
1. Processes (i.e. Management, Quality, and Engineering)
2. Systems(i.e. the Space System, composed of Space Segment
and Ground Segment).
The reasoning for standardizing Processes is to improve quality and
reliability, and to allow for cross support in testing.
The benefit of standardizing Systems is improved reliability,
collaboration, and cross support during development and operations.
The table of contents is here:
https://drive.google.com/open?id=0B_-jwG2gLchfa19KeHBsc1B6cWM
End of the year this handbook will be published as freely available
open book. Before that, it would be extremely useful to get extensive
feedback and review of the draft.
If you would be willing to contribute as a reviewer and receive the
draft, please provide the editor, Artur Scholz (artur.scholz@xxxxxxxxx.xxxx
the following details of you:
- full name
- email
- short background about yourself and experience with CubeSats/SmallSats
Your feedback on the draft will be duly acknowledge in the final book!

Satellite Operations From the Grand Canyon National Park
Patrick Stoddard, WD9EWK/VA7EWK, reported that the ARRL just released the
July issue of their National Parks on the Air (NPOTA) newsletter for
National Park Service staff and volunteers.
On the last page of this month's newsletter is a short mention of one way
to deal with an "uncooperative ionosphere" - work satellites. It shows
Fernando Ramirez, NP4JV, working a satellite from the South Rim of Grand
Canyon National Park in northern Arizona.
These newsletters are at:
http://www.arrl.org/npota-for-nps and the July issue is available at:
http://www.arrl.org/files/file/NPOTA-News/NPOTA-July2016.pdf
Fernando commented, "It was a nice surprise to find our picture on this
month's ARRL National Park on the Air newsletter! I am humbled by the
mention.
"I'm also happy to see that some of our trips and portable operations are
helping to promote AMSAT and their goal of 'advancing the state of the art
in space science, space education, and space technology.'"
Fernando frequently posts reports of his satellite operating activities
via Twitter where his ID is @xxxxx. You may also visit:
http://twitter.com/NP4JV to see his activities, including the photo
that got his name in the news.
Sean Kutzko, KX9X, at the ARRL wrote via the AMSAT-BB, "It was an easy
choice; that photo is amazing!"
Congratulations, Fernando!

Radio Amateurs Invited to 10 Downing Street
Radio amateurs were invited to a reception at the UK Prime Minister?s
residence
to celebrate the successful mission of UK astronaut Tim Peake KG5BVI /
GB1SS.
Sandringham school student Jessica Leigh M6LPJ and her head teacher Alan
Gray
G4DJX attended the event with Tim Peake GB1SS. Italian astronaut Samantha
Cristoforetti IZ0UDF and the UK?s first astronaut Helen Sharman GB1MIR also
attended.
Jessica was the first UK school student to establish amateur radio
communications with Tim Peake during his six month mission on the
International
Space Station. The contact took place on January 8, 2016 and was featured on
national TV and in the press.
Year 10 pupil Jessica M6LPJ, along with two other students Polly M6POG
and Emma
M6GJQ, passed her amateur radio Foundation exam just before Christmas
2015 after
training with the Verulam Amateur Radio Club.
Sandringham school caters for 1300 students aged 11-19 with 100 teachers
including specialist teachers of computing science and three female physics
teachers all of whom have a specialist interest in space and astronomy. In
addition, the head teacher Alan Gray G4DJX is a very active radio
amateur who
was extremely supportive of the ISS contact.

My wife and I will be traveling from Hobby airport to the Doubletree hotel
in Galveston on Wednesday, Nov. 9 about 6 PM. Is anyone else traveling
around that time interested in sharing costs (van, limo, or whatever)?
I?m also interested in someone to share travel to the Johnson Space Center

Just now on FO-29, I observed and recorded part of some strong FM QRM. These
signals corresponded to an uplink of 145.900, and were from at least two
sources, as there was a Spanish language QSO (of which I caught one US
callsign), and a possibly non-amateur QSO in English with a northeastern
accent and foul language. One or more of these may be originating from an
Echolink node or similar gateway outside of the identifying station's
control. I want to put this recording out there for anyone who might know or
recognize the stations, and anyone that may hear something I didn't. The
recording ends at about 16:08:15Z today.

Sounds like the northeaster is using a 229.1 Hz tone, if that might help
in guessing a repeater.

Interesting. By the pace of the conversations, the SSB guys don't sound
like they know they only have a few minutes to wrap up the QSO. Bad
language etc. aside, they might be using simplex on that frequency and
probably don't realize they transmitting on a satellite uplink
frequency. Just a theory...

The Spanish-speaker's Call sounds like KD4MDF after listeningto it multiple
times. ?Kilo-Delta-Cuatro-Mike-Delta-Fauxtrot?He slurs the last letter. That

I imported the mp3 file, used filters to zero out anything below 1000hz and
above 5000hz, then reduced db gain of 3000 hz center. Copied the results,
then re-ran the processed audio with 20db gain. Headphones. I might try
running original through my SDR and tinker with outputs.

Did you try any noise gate filtering?

No I didn't, just pure audio filtering. Everything above 5000hz was very
distorted by noise. Everything below about 850hz was also distorted by
phase noise. I just did a quick and dirty for the voices. The US guy was
pretty clear around 1500 hz, high pitched voice.
I didn't hear a side tone, but probably missed it.
I would guess that the US guys were using what they figured was a clear
channel and running high power with a directional antenna. Most likely a
good ole boys' intercom. Some of the good ole boys' around here run a
couple hundred watts, a horizontal yagi, and SSB. Your guess as good as
mine. Not enough other data for me to call in an air strike.
The Spanish language might well have been a legitimate FO-29 QSO, we just
heard one side of it. Wonder what the orbit foot print looked like at that
specific time?
