There are a huge number of tracking/station control programs out there. We
eventually pick one that meets our needs and learn how to use it. My main
interest is in the user interface and ease of use. When we use any program
for a long time it starts to seem to seem to be intuitively obvious how to
use it in much the same way a carpenter finds it intuitively obvious that
the next mark on the ruler past 19/32 is 5/8. Here is a short video showing
parts of my feeble attempt. There might be an idea or two in there that you
can use or a nit or two that you can pick.
It will look a bit better if you select 480P and use full screen.

Hi,
Thought I would give the ARISSat transponder a try.
Any recomendations from those that have worked it.
I have available a 9 element yagi and?about 20W at the feed point ?
Is this likely to work or do I need a few kW ?
Thanks

Just my 2 cents worth,
Whichever side of the debate you happen to be on, and I can see both sides,
there is one thing to be said in favour of the so called "beep sats"
They keep our frequencies warm whilst we wait for bigger and better satellites

Hello AMSATs,
As we all know OSCAR is the abbreviatie of Orbiting Satellite Carrying
Amateur Radio.
To my opinion the function of OSCAR satellites is to facilitate
communication between amateur radio stations using amateur radio
frequencies and/or do experiments on those radio frequencies.
Can someone tell me how it is possible that many of the newer small
satellites get a license to use ham radio satellite frequencies for only
broadcasting data ?
Many of these satellite? missions are even not ham related, and those
satellites only have a broadcast (downlink) radio onboard.
Is this nowadays seen as amateur radio communication ?
The word "Education" I read in many of the university CubeSat projects.
Doing experiments on ham radio frequencies is like education, and I fully
support this even when it is only available as a downlink at a CubeSat.
When it comes to the education of building a satellite, with no ham related
experiments, and where the amateur frequencies and the amateur community is
used to collect only none ham payload data, I don't see this as a ham
satellite.
Then a 433MHz remote control toy-car should also be named a ham radio.
We just ask one of those ISS astronauts to throw this toy-car out of the
space station and we have another amateur satellite :o)
I just wonder where is the border between an OSCAR and a satellite that uses
ham radio frequencies for downloading its (none ham)
payload data ?

Hi William, PE1RAH
Yes, I agree with you, but you and I we are talking always to the same
people and some of them probably with their own interest as they are
closely connected to some CubeSat projects.
Most of them have no "satellite ham spirit" since they did not make the
experience we did with OSCAR-6-7-8 + the RS + the FO and than with
OSCAR-10, OSCAR-13 and AO40
My experience is, that they even don't want our support and advise..
from experience here in Italy, they don't trust and know everything better
anyway.. they even don't trust other Universities within the same
country, they see it more as a competition rather than a cooperation..
Every time I write........"to my opinion the function of OSCAR satellites is
to facilitate two way communication between amateur radio stations using
amateur radio frequencies and/or do experiments on those radio frequencies"
........I get insult from the above people because probably you and I we are
considered as two of those old "RF dinosaurs" that like to experiment into
space RF circuits building equipments and antennas? from the VHF to
Microwave.
I believe that things will change only when a HEO satellite will be in
orbit, hopefully P3E, because everyone will switch to it abandoning the
actual non ham payloads and will stop to collect telemetry data for no
ham related experiments.

John,
I hear my signal back very well with an 18 el crossyagi and 40 W TRX
output. However so far nobody came back to CQ. I think your setup should
work. Try CW.
How about a sked tomorrow for the passes around 10:07 and/or 11:42?

Hi Stefan,
So the answer on my question if my 433MHz toy car, when I put it into space,
can get an OSCAR number is YES!
According to the AMSAT website you mentioned of course... :-P
- My question was not specific if these satellites can or can't get an OSCAR
number.
My intention was more if they should be scheduled as a ham-sat (and with
that using ham frequencies).
I would recommend you to read the following IARU website!
http://www.iaru.org/satellite/prospective.html
(especially section VI. OPERATIONAL GUIDELINES)
It says the following:
"Organisations building satellites should compare their mission plans to
the requirements of the amateur-satellite service. Then, they should
determine if it is possible to comply with the requirements of the
amateur-satellite service or if licensing and operation should be in
some other radio service which is more consistent with the nature and
requirements of the mission.
A. The purposes of an amateur satellite should be:
(1) To provide communication resources for the general amateur radio
community and/or
(2) To conduct technical investigations in all respects consistent with the
Radio Regulations. [See RR S1.56 and RR S1.57.]"
I have great doubts with many off those CubeSats, if they comply to number
(1)....
The only communication resources they provide is for themselves by a cheap
downlink system, by using hams to receive data for them. This is not for the
general amateur radio community as mentioned in number (1)...
The option they have is to go to "some other radio service which is more
consistent with the nature and requirements of the mission."

Hi John,
With the antenna that you have I am sure that you should have no problem
hearing your own downlink and maybe getting someone to respond to your calls.
I had confirmed contacts earlier in the season when ARRISat-1 was first
making passes and active during daylight hours here in the UK.
My set up is just an "Elk " antenna mounted on a well made tripod, I put
together a unit with a motor for rotation and tracking via any of the usual
forms of software available - Mainly use SatPC-32.
I have tried my Kenwood TS2000 or FT 736 and also an FT857 ( this does
not have duplex operation)
In terms of power which was your main question - I am using around 20 watts
from the transmitter on UHF
for the uplink on SSB.
This is also my set up for many other contacts and operation and also use
a Kenwood THD 7 for AO-51.
During the past week while ARRIS -1 has once again been in good favour for
daylight hours I have made regular CQ calls and heard my own downlink but
sadly had no response from anyone.
The very short time that you get of course with the satellite switching
off makes it harder to get into the bird
I listen for the rapid rise in the level of noise generated then use CW to
look for my downlink ( around 145.290 Mhz) The signal level varies
around S5 -S6 at best.
Need to make the most of the current favourable conditions for this part of
the world as with shorter hours of daylight and with regression it won't
be long before loose operation for a spell.
I wish you luck and look forward to hopefully hearing you active so that I
can get another confirmed contact
in my log.
Congratulations to you on your success with the decoding of the BPSK -
Maybe I should also be looking
at following in your footsteps.
Regards
Ken Eaton

I would like to first say that yes, many of these Cubesats projects do a
really poor job of providing information about themselves and they have a
lot of room for improvement.
Second that amateur bands are used not only for the fact that there are
already established ground stations, but because getting licensed on some
other piece of spectrum is a substantial investment of time and money, and
many of the student projects simply don't have excessive reserves of
either. Granted many of them would love to move off amateur bands, find a
little open spectrum in the GHz range where they can blast data down at
some incredible speed, in which case they could move more data in a few
seconds then they could collect in a day, which makes things many design
issues much easier. Alas when you tell a student to start filling out
paperwork that may get a response before they graduate, and until then
there isn't much they can do until they can lock down that parameter,
chances are if they are smart they will run off to do something else like
build a race car, or a robot and you loose someone else in the next
generation of rocket scientist.
Thirdly I have been reading the AMSAT-BB's for several months and I can see
why there wouldn't be many people working on CubeSats hanging around. In
order for anything productive to come of discussions like this, people from
the CubeSat community need to be more involved but they aren't going to be
inclined to do so when the conversations reads like dialog from "Grumpy Old
Men". Nano and Pico Satellites aren't a simple evolution
of existing technologies but a large paradigm shift, one which I don't
think anyone even now fully understands. When you don't have
thoughtful discussions between both sides issues don't get addressed, and
everyone's feelings get hurt. I would suggest using cubesat.org as a
starting point.

Project OSCAR Newsletter November 15, 1961 at 1345 PST
First News Release,
U. S. RADIO AMATEURS T0 LAUNCH "PIGGY-BACK" SATELLITE
SUNNYVALE, CALIF. -- A hitch-hiking radio transmitter that will speak to
thousands of amateur radio operators throughout the world is scheduled to be
launched into space orbit next month, announced the American Radio
Relay League.
Weighing only 10 pounds, the satellite has been designed, built and tested
by a
group of California (Peninsula) radio amateurs organized as the Project Oscar
Association of the League.
"OSCAR" stands for Orbital Satellite Carrying Amateur Radio. The radio "ham's"
transmitter beacon will be carried into space aboard a scheduled space vehicle
and will radiate signals in a world-wide amateur frequency band of 2-meters,
radio amateur M. C. Towns, Jr. (Saratoga, Calif.) announced today.
Transportation into space will be provided by an Air Force vehicle to be
launched from Vandenberg Air Force Base, Calif.
Once in orbit, the Air Force vehicle will "kick away" the piggy-back radio
amateur satellite, leaving it to follow its own course around the earth. The
mother satellite will then continue to perform the experiments for which it
was
intended. Radio Amateur Towns, the Oscar Association Chairman, stressed that
Project Oscar "is a serious, civilian, non-commercial effort to obtain
information from outer space, and to introduce radio amateurs and lay
scientists
to new concepts in outer space communication.
"This miniature radio transmitter will be tracked and observed by
radio amateurs
and all interested observers throughout the world. "It will serve to instruct
the radio amateur in the art of observing and tracking a moving space
object. In
addition, the mass of data gained from world-wide observations will provide
information unobtainable by any other means.
"There are an estimated 300,000 licensed radio amateurs in the world, and the
American Radio Relay League hopes a large number of these hobbyists will
participate in the forthcoming experiments."
Towns noted that the radio amateur has, in the past, been a pioneer in various
fields of radio communication, and that hundreds of U. S. radio
amateurs are now
engaged in space research and other space activity.
The 10-pound Oscar satellite consists of a low-power beacon transmitter
contained in a rectangular metal casing about a foot long. It will send out a
continuous Morse code signal of the letters H-I, four dots followed
by two dots.
Later satellites proposed to be built by the Oscar Association may both
receive
and transmit amateur signals.
As soon as this transmitter is in orbit, notification will be flashed to radio
amateurs throughout the world by the American Radio Relay League, the
international organization of radio amateurs which is sponsoring and
cooperating
in the project. "Radio propagation, Heaviside layer refraction, antenna
efficiency and other data can be gathered and correlated from thousands of
points over the world's surface," Towns said.
"The cause of good will," Towns continued, "will be served in that radio
amateurs, located in virtually every country of the world, would have a common
amateur interest in observing and tracking their own satellite, and in
exchanging scientific information relative to improved equipment for receiving
the satellite signals."
The Oscar transmitter is designed to operate on a frequency of 145 megacycles
and can be heard by home experimenters having simple receiving equipment,
Towns
said. "Cooperation in the forthcoming tests is invited from any interested
party," the Oscar Chairman stated, pointing out that support has already been
contributed by the Air Force and numerous private concerns interested in
furthering communication knowledge, and entirely on a no-cost basis
of lending a
helping hand to the amateurs in their own project.
The radio amateur satellite idea originated in 1959 with a Los Angeles amateur
operator, Don Stoner, who suggested that radio amateurs had the technical
know-how to build their own satellite if someone only had the vehicle to carry
it into space. He, along with radio amateur Fred Hicks, of Campbell,
California,
and other radio "hams" kept the idea alive and formed the Project Oscar
Association. The idea spread among radio clubs of the Los Angeles and San
Francisco area and gathered support from radio amateurs nation-wide, including
the radio amateur organization, the American Radio Relay League.
Radio "ham" Nicholas K. Marshall, technical director of the Oscar
program, noted
that the soon-to-be-launched satellite is but a first step in the overall
Oscar
concept.
"Later satellites to be built by the Oscar group will perhaps receive and
transmit amateur test signals for specific space experiments," he
said. Marshall
noted that there are approximately 12,000 radio amateurs in the Soviet Union,
and that the Oscar Association hopes to receive tracking data from some of
them
also.

On November 8 AMSAT-UK posted the news that the UK space Agency and
Astrium have approved the final design of UKube-1 - the UK's first
CubeSat mission. The full story can be read at:
http://www.uk.amsat.org/2011/11/08/ukube-1-final-design-approved/
On November 3-4 a young team of engineers from Clyde Space presented
their final design to a team of experts for the Critical Design Re-
view (CDR) - the typical 'gateway' for space missions to proceed
into the flight build and implementation phase.
The CDR for Ukube-1 thus marks an important point in the development
of the mission, establishing the robustness of the design, the level
of technical risk and the schedule/resourcing for the completion of
all the tasks to build the flight spacecraft.
At the CDR, the review panel scrutinized the design in detail to
ensure it was sufficiently mature for flight. Key areas of focus
included the structure and mechanisms, the communications system,
the on board software and processing, the attitude control system
and power generation.
At the end of the meeting the review board concluded that Ukube-1
had successfully passed CDR.
The next stage is the implementation of the mission that will lead
to a launch on a Russian Dneper rocket (ex ICBM converted for small
satellite launches) towards the end of 2012.
More on the aims and objectives of Ukube-1 can be found on the UK
Space Agency website:
http://www.bis.gov.uk/ukspaceagency/missions/ukube-pilot-programme
The UK Space Agency's pilot programme to design and launch a CubeSat, a
miniature cube-shaped satellite that will allow the UK to test cutting-edge
new
technologies in space. In March 2011 four payloads were finally selected to
fly
on UKube-1. These will be integrated onto the spacecraft, which measures just
10cm x 10cm x 34cm, by Clyde Space. In addition UKube-1 will fly FunCube, an
educational payload provided by AMSAT-UK, with the goal of enthusing and
education young people about space, electronics, physics and radio.

worked. There are several satellite ready hams in EM55: WA4NVM,
WA4HFN, WB4LHD, WA4OVO, KI4OTG, KD4NOQ, KJ4BIX, AJ4KF, W5KUB,
N4MGT AA4HV K4FEG. Send your log to WA4NVM or WA4HFN for checking,
along with your current mailing address. The award is free and
should any donations be sent, they will be forwarded to AMSAT along
with your call and name. This award is effective for contacts made
beginning on 1 June 2011.
+ The Super Sensitive High Definition TV, or SS-HDTV, camera on the
space station can document new and more detailed footage of the
dynamic interactions that take place in the area between the Earths'
atmosphere and the vacuum of space, known as the cosmic shore.

1. Swiss Students Speak with Astronaut Aboard ISS
On Monday, October 31, students attending Kantonsschule Zug in Zug,
Switzerland
connected with Astronaut Mike Fossum, KF5AQG on the ISS via Amateur
Radio on the
International Space Station (ARISS). An audience of 600 was on hand to witness
the contact and watched as 8 students got in 16 questions before the ISS went
over the horizon. The contact highlighted lessons on gravity, orbits, the ISS
and its flight path, as well as electromagnetic waves and amateur radio. This
ARISS event was held in celebration of the school's 150th anniversary. Media
coverage included two television stations and one radio station.
2. Californian Students Radio ISS Astronaut
San Diego, California students from Sundance Elementary School participated in
an Amateur Radio on the International Space Station (ARISS) contact on
Tuesday,
November 1. Astronaut Mike Fossum, KF5AQG answered questions about the ISS
mission, space and how space affects the human body. The contact was
integrated
into lesson plans about radios, radio waves, space and space-related
topics. The
local ham radio club gave presentations to the youth. Sign On San
Diego covered
the event in an article:

Thanks,
Cubesats working within the amateur radio frequency spectrum are
commanded by licensed ham radio operators with the same rights and
requirements as all of us. Many of them use the frequencies to
downlink vital satellite information as well as scientific experiment
data. All of this is well within the amateur radio service rules and a
very positive contribution by our community to science and education.
Your question are valid and they need to be addressed in a
constructive, supportive environment where the community works
together. I would encourage you attend one or more of the many annual
cubists conferences and engage these folks. You certainly have enough
to offer!
Now having said that, cubesats are a wonderful addition, not a threat
and show the diversity of our community. I am always amazed by the
ignorance displayed and self-proclaimed expert label used by some as
an argument to deny parts of our community their right to use small
satellites with amateur radio on board. Interestingly, none of the
amateur radio operators working with cubesats have ever argued against
HEOs or denied the rest of us that right by questioning how and why we
use the spectrum!
Fortunately, AMSAT NA and AMSAT UK and many others have recognized the
potential and the inclusiveness of the community.
Enough said,
Stefan, VE4NSA

>> ... "OSCAR" stands for Orbital Satellite Carrying Amateur Radio ...
Why was it changed to "OrbitING Satellite Carrying Amateur Radio?"
Did "Orbital" just sound too geeky for the masses?
YES - the early citations from the 1960s had it as "Orbital."
WHO changed it to "Orbiting" ???
