Message-ID: <20160911113137.D6763222A4@xxxxx.xxxxxxxxxxxxx.xxx.xx>
Content-Type: text/plain; charset="us-ascii"
I am finding it very difficult to successfully receive/decode telemetry from
AO-73 and Ukube-1 using an IC-9100 and SatPC32 as compared to receiving same
when using an IC-821H.
Are there any hidden/secret settings on the IC-9100 which have to be set to
allow successful reception/decode of the telemetry. Should one be trying to
receive with the IC-9100 in the Digital mode?
Is there a command which one can enter in the Doppler.sqf file in SatPC32
(like DFM which puts the IC-9100 into Digital FM mode) to put the IC-9100
into the Digital mode for USB reception?
I did try DUSB entered into the Dopple.SQF file of SatPC32, but this did not
work.
I have tried several different settings in the menu section of the
transceiver, all to no avail.
Using the IC-821H I can receive/decode the telemetry from about 5 degrees
elevation (going up) to 3 degrees (going down), but with the IC-9100 I do
not start to receive/decode until the satellite is about 25 - 30 degrees
elevation (up) and then lose it when the satellite is about 20 degrees
elevation (down). Using the same antenna system on both so the antennas can
not be having a large effect on the IC-9100. Plus decoding is constantly
stopping during the pass, thus missing a large amount of data unlike the
IC-821H which hardly ever stops decode during a pass.
Appreciate any suggestion one may be able to provide.

Of course, that assumes ou can see down to the horizon. If you are
surrounded by buildings or trees or mountains that are higher that, then
adjust antenna to that elevation.

Hello Cor
I enjoyed the event today.Managed to work a few PA, DL, OZ and a /MM station
thru the transponder. Copied it well with a signal S9- S9+60db on the
TS-790e meter constantly, with fading.
No preamps on the satellite antennas here, 2*7el 2m and 2*12el 70cm crossed
yagis (half lenghts from Maspro system WHS-32N).
TOO BAD that some people do NOT like to hear DX, and used it for a local
chat. But it worked great!!

Onderwerp: [amsat-bb] Sunday 11 september 2016 balloon fox hunt with U/V
FM transponder!
Hello radio friends,
At Sunday 11 september 2016 is a balloon fox hunt event.
A weather balloon will be launched with U/V FM transponder, 23cm ATV
transmitter and
beacon (tone) transmitter.
The weather balloon will be launched from the Netherlands, amateur radio
stations in nearby -
countries have to wait a while to hear the signals untill the balloon reach
an higher -
altitude! (the maximal altitude might reach 30km it also did in the past!).
------------------------------------------------------------------------------
-
Balloon transmitters frequency information:
Beacon: 145.450 MHz (100 mW FM/N).
FM crossband voice transponder uplink: 432.550MHz downlink: 145.475MHz (1
Watt FM/N).
ATV video transmitter 1252 MHz (1 Watt FM, camera looking down to earth).
The balloon camera video stream can be world wide seen on the website (see
the urls below).
------------------------------------------------------------------------------
-
Ground control stations:
PI4RCG 7.080 kHz, 3.650 kHz (+/- 10kHz QRM).
PI2NOS 430.125 MHz (+1.6 Shift) ground repeater in the Netherlands (also
audible via echolink).
PI3UTR 145.575 MHz (-0.6 Shift / 77Hz) ground repeater in the
Netherlands (also audible via echolink).

> Also, as Bob Bruninga will tell you, set the EL at 15-20 degrees.
Following Bob's advice here for fixed elevation of 20 degrees works well.
I've got my 6 element 145 MHz and 8 element 435 MHz cheap yagis on a TV
rotor.
On 145 MHz I can copy and decode the AO-73 weekend mode beacon ~37 mW at 700
miles range with no preamp.
I've found that the tighter beamwidth of 8 elements on 435 MHz requires
closer tracking (manually) and occasionally I need to wait for the
satellite's elevation to get low enough to get back in the antenna pattern.
A basic setup like this will get you on the air. There is plenty of room for
improvement but that is part of the fun too.

Hello radio friends,
The balloon fox hunting was a big success today.
These events are one of the biggest amateur radio events in the Netherlands
there where a lot people
in cars trying to find the balloon first.
And thoussands amateur radio operators have tried to make radio contacts via
the balloon U/V FM voice transponder.
That was not easy with only one channel!
The weather balloon was exploded at 30.6 kilometers height.
I have heard stations from: Belgium, Germany, Denmark, UK and ofcoarse a lot
from the the Netherlands.
I had expected more stations from nearby countries with my posting on
amsat-bb but in comparisation with
other years there where not much more.
A special thanks for the QSO with Jerry ON4CJQ in Belgium!
Every year is a new balloon fox hunt event in september so keep watching the
official website.

RadFxSat (Fox-1B) launch date is now scheduled for March 16, 2017
The RadFxSat (Fox-1B) launch date has been moved, and is now scheduled
for March 16, 2017.
RadFxSat will ride as one of the ELaNa XIV secondary payloads aboard the
NASA JPSS-1 launch on a ULA Delta II rocket.
The launch will be at Vandenberg AFB, California. It is one of only two
remaining Delta II planned to be launched.
The RadFxSat mission is a partnership with Vanderbilt Institute for
Space and Defense Electronics (ISDE) that will study space radiation
effects on commercial off the shelf memory. The experiments are carried
aboard the AMSAT Fox-1B CubeSat and experiment data will be carried in
the subaudible telemetry stream of the Fox-1B FM repeater along with the
CubeSat telemetry data. The telemetry can be decoded and displayed with
the AMSAT FoxTelem software.

?Frequency Crunch? is ARRL/TAPR Digital Communications Conference
Sunday Seminar Topic
?Spectrum (It?s the frequency crunch for real)? will be the Sunday Seminar
topic at the ARRL/TAPR Digital Communications Conference (DCC) September
16-18
in St Petersburg, Florida. Michelle Thompson, W5NYV, and Bob McGwier, N4HY,
will moderate the tutorial.
?The Amateur Radio spectrum above 450 MHz is facing serious threats. The
demand for useful spectrum is large and growing,? an abstract for the
presentation asserts. ?We will explain why this spectrum is in demand
and what
you need to know and do in order to defend it.?
The presentation will offer a practical understanding of digital
communication, software-defined radio, codecs, protocols, and cognitive
radio.
Thompson heads the AMSAT Ground Terminal Team, a component of the so-called
?five and dime (5 GHz and 10 GHz) Phase 4B geosynchronous satellite project.
McGwier is chief scientist at the Hume Center for National Security and
Technology at Virginia Tech.
The Saturday night banquet speaker will be ARRL Chief Technology Officer
Brennan Price, N4QX. His topic will be ?New Frontiers in Wireless:
Challenges
to and Opportunities for Amateur Radio.?

5 Teams Share First Round of NASA Cube Quest Challenge Prizes
Five teams, ranging from university students to a group of engineers
dispersed
across the country, received $20,000 each from NASA in the first
milestone of a
competition to develop deep space CubeSat technologies.
The teams, announced by NASA at a Sept. 9 briefing, had the highest
scores in
the first of four ?ground tournaments? that make up the initial phase of the
agency?s $5 million Cube Quest Challenge. That tournament, held in early
August, featured 13 teams who presented their initial spacecraft designs.
?Cube Quest is an opportunity for non-government CubeSat developers and
builders to compete in lunar orbit and deep space for accomplishments in
communications, navigation and longevity,? said Jim Cockrell of NASA?s Ames
Research Center. Cockrell is manager of the competition, part of the
agency?s
Centennial Challenges prize program.
- See more at:
http://spacenews.com/5-teams-share-first-round-of-nasa-cubesat-
prizes/#sthash.qbwJKlXB.dpuf
The ground tournaments are optional elements of the overall competition,
intended to guide teams through the development of their spacecraft as they
mature from initial concepts to flight hardware. Participating teams are
scored
on how well they meet the requirements of each tournament, and the three
with
the highest cumulative scores will win flights of their spacecraft as
secondary
payloads on the first Space Launch System mission, Exploration Mission 1
(EM-
1), in 2018.
The first ground tournament did not involve any hardware, and Cockrell
likened
it to a mission concept review that takes place early in the development
of a
typical NASA mission. Judges assessed the capabilities of each proposed
mission
and compliance with mission rules and SLS safety requirements.
?It was the first opportunity for teams to present their concepts for
how they
intend to win the Cube Quest Challenge,? he said. ?Ground Tournament 1
demonstrates that teams are on a good trajectory for launch on EM-1.?
Some of the winning teams are linked to universities that have
experience with
CubeSats. A space systems design class at the Massachusetts Institute of
Technology started work on the KitCube spacecraft this spring, said Kerri
Cahoy, a professor of aeronautics and astronautics there. KitCube is
designed
to go into lunar orbit and demonstrate a laser communications system.
Another team, Cislunar Explorers, is composed mostly of students at Cornell
University. ?The work represents the culmination of lots of Ph.D.-level
research and some undergraduate research from the last five or six years
at the
university,? said Mason Peck, a Cornell engineering professor who served as
NASA chief technologist from 2011 to 2013.
Peck said their spacecraft will demonstrate several key technologies,
including a propulsion system that uses solar power to convert water into
hydrogen and oxygen propellants. ?It?s a pathfinder for the sustainable
exploration and settlement of the solar system,? he said.
Other winning teams have less traditional backgrounds. ?There?s 12 of us
across the United States? working on Team Miles, said team leader Wes Faler.
Many of them are located in Tampa, Florida, including Faler, but others are
based in California, New York and South Carolina.
Faler said the team takes its name from a line in a Robert Frost poem: ?And
miles to go before I sleep.? After going into orbit around the Moon, he
said,
the spacecraft will perform an extended mission, traveling towards Mars
to test
autonomous navigation technology.
Ragnarok Industries of Wilmington, Delaware, was established by a group of
former engineering interns at NASA?s Goddard Space Flight Center. Their
satellite, Heimdallr, is intended to test advanced propulsion and
communications technologies for missions beyond Earth orbit, said
company co-
founder Luigi Balarinni.
Novel Engineering of Cocoa Beach, Florida, is working with several other
local
companies, including Craig Technologies and Harris Corp., the latter
providing
a deployable mesh antenna for its CubeSat, named Space Pig. The name, team
members said, came from elementary school students during an outreach event.
The ultimate goal of the competition is to fly CubeSats into lunar orbit or
deep space. A total of $3 million is offered in prizes for the ?Lunar Derby?
part of the competition, for both being able to enter lunar orbit and to
demonstrate communications capabilities and longevity. An additional $1.5
million is for a ?Deep Space Derby? to achieve communications and longevity
goals.
NASA?s Cockrell said the next ground tournament is scheduled for early 2016.
Teams can participate in that round, which he compared to a preliminary
design
review, regardless of their performance, or even participation, in the
August
tournament.
Teams that do not participate in the ground tournaments, or who do not
finish
in the top three in total points, can still pursue the deep space and lunar
prizes by arranging their own launches. The competition ends, and any prizes
awarded, one year after the EM-1 launch

5 GHz to 10 GHz Lunar Transponder Mission
AMSAT-NA plans 5 GHz to 10 GHz transponders on a spacecraft expected to
launch
in September 2018 into a Lunar orbit.
Heimdallr is a 3 axis stabilized 6U CubeSat with a mass of approximately
8 kg.
It will have a Cold Gas Thruster for inertia dump and a star tracker for
navigation. Deployable, gimbled solar panels will produce up to 100
watts of DC
power, electric propulsion will be used to achieve lunar orbit.
There will be a combination of omni and directional patch antennas on
one side
of spacecraft.
The first part of mission is to provide Telemetry, Tracking, and Command
(TT&C) to obtain lunar orbit. The second part is to perform the data
downlink
experiment while the final part is to provide a two way regenerative
repeater
and analog repeater in lunar orbit for lifetime of satellite.
Proposing these downlinks:
? Omni transponder: 10.451 GHz +/- 0.5 MHz
? Directional transponder: 10.4575 GHz. +/- 3.5 MHz
? Analog transponder: 10.4665 GHz. +/- 2.0 MHz
For the first part of the mission (TT&C) using 300 bps BPSK 1/2 rate viterbi
Ranging 1.5 Mbps BPSK DSSS. For the second part of mission 4.5 Mbps QPSK ?
rate DVB-S2. For the final part of mission 25 kbps BPSK 1/5 rate DVB-S2.

Susan Buckle will be giving a presentation at the RSGB Convention on
Saturday,
October 8.
Along with Ciaran Morgan M0XTD, she will talk about the ten UK ARISS amateur
radio school contacts with astronaut Tim Peake GB1SS during his Principia
mission on the International Space Station.
These contacts have inspired thousands of young people and introduced
them to
amateur radio in a new and exciting way.
The full schedule and booking information for the convention are
available at
http://rsgb.org/convention Twitter hashtag #RSGBconv2016
An RSGB video celebrates these historic school contacts and the range of
linked activities the schools have enjoyed.
Beginning with the exhilaration of the launch, it follows the
competition for
schools to host the ARISS contacts, and showcases the variety of science,
technology, engineering, maths (STEM) and arts activities that helped
pupils to
understand more about space and amateur radio.
The contacts themselves, often led by newly-licensed pupils, were the
successful culmination of many months of work and anticipation.

Satellite Shorts From All Over
K6R Coundtdown
On September 16th, Wyatt, AC0RA, and myself will be getting on the boat in
Ventura, CA with our destination set on CM93. We've been training all
summer, finalizing equipment, setting skeds, and generally getting all the
loose ends tied up, and we look to be ready to go.
We have posted our Final pass schedule on the K6R QRZ page at
https://www.qrz.com/lookup/K6R
- so feel free to find a pass that is to your liking. We have tried hard to
include everyone in our distance range on at least 1 or 2 passes. Of course
all passes are dependent on weather, schedule, and other factors - and
there's
a very good chance we'll show up on passes that AREN'T on our list as
well..
find a window, and see if we're around.
We're also happy to announce that Jimmy, KK6FAH will be serving as our
pilot relay station for the expedition. He's a fellow AMSAT operator, and
has a QTH right in Ventura, and we should be in local repeater range of
each other while we're on the Island. We have agreed to meet up each
evening and report our logs to him, and he will then pass our report on to
the BB. Please do not email him with questions about busted calls or the
like, he's simply going to be passing on our reports. He's also been
awesome in helping us with some local arrangements, and we appreciate his
assistance with this project greatly.
I'd also like to make a brief request for folks to use some good
situational awareness while we're out there. We know this is a rare grid
and there's tons of interest, but remember that the birds and pass time are
a scarce resource. We're hoping with lots of scheduled passes there should
be more than enough air time to get everyone worked that wants it, but use
some common sense. If you have linear capability, find us on one of those
birds, and leave SO-50 for the FM only operators. If you're on the West
coast and can work us on a higher pass where the east coast doesn't have a
footprint, consider delaying to give them a chance. If you can handle
taking a night off from using SO-50 as your ragchew repeater in the sky,
that'd be great too... and please try to keep the dupes to a minimum - you
never know when someone is just sliding into the footprint and only has 30
seconds to make that precious QSO. Thanks in advance.
Finally, we're planning to do a very informal round table on 20 meters
Saturday night at 8:00 PDT. Clayton, W5PFG has agreed to find us a
frequency (probably the upper portion of 20m) and send out a tweet on where
we will be. We'd love to have you stop by on HF and chat about Satellite
stuff, the expedition, or "Am I in the log?" that night.
It's expedition go time. Hope to catch everyone from CM93!
