I recently attended the HackerSPACE conference in Kentucky hosted by Prof.
Bob Twiggs. I too was a Cubesat non-believer but after attending the
conference I came away with a new perspective. Universities are not given
"gift certificates" for free launches, they must compete for them with their
sponsor (a.k.a. the guy that is paying for the launch) in the same manner
that AMSAT has recently submitted a proposal. These proposals are evaluated
and the ones that the sponsor deems best qualified are given an opportunity
for launch. Since the sponsors are promoting STEM education, that's what the
proposals are evaluated on. The more educational content the better the
chances to fly. The good news for us is that from what I observed at the
conference, universities would be very happy to have assistance in the
design of their communications package. Not only do we bring years of
communications experience and a world wide monitoring network but we also
offer actual hardware and techn!
ical support for free. Adding state of the art communications capability to
a scientific/education payload increases the chances for a launch. Everybody
wins in this scenario. The problem as I see it is not technical at this
point but one of marketing. We need to turn the discussion educating the
educators on the benefits of working with AMSAT. Almost half of the
attendees at the HackerSPACE conference had no idea who AMSAT was or what
they did. We were very lucky to have Prof. Twiggs there and the folks at
Kentucky Space to include amateur radio as part of the conference. If we are
unhappy about what universities are flying then it's up to us to fix it by
making our presence known. The AMSAT engineering team has already proved
they can build either FM or linear transponders into the right size package
now we need to sell the product. We all need to become sales people and try
to find the leads that could be our next launch opportunity. Of course this
is just my opinion, y!
ou may have a different one :)

Several recent postings by individuals show that they have clearly not taken
the time to read the international agreements to which all of our amateur
satellite service spacecraft abide. There are MANY allowable uses of the
amateur satellite service spectrum other than launching transponders for
hams to jawbone back and forth.
If you'd take time to educate yourself on the rules that your hobby abides
by, you would find that the following applies:
"The purposes of an amateur satellite should be to:
(1) Provide communication resources for the general amateur radio
community and / OR [emphasis added]
(2) Self training and technical investigations relating to radio technique.
[See RR 1.56, 1.57, and 25.2.]
"Radio technique" means having a reasonable possibility of application to
radio communication systems. Examples relating to radio technique include,
BUT ARE NOT LIMITED TO [emphasis added]:
? communication protocols
? attitude determination methods
? command and control procedures
? receivers, transmitters, and transponders
? antennas
? sensors to study spacecraft performance
? telemetry protocols
? power controls and supplies for use in space
? spacecraft computers, memory, operating systems, programs, and related items
? radiation effects on electronic components
? radio wave propagation
? meteor trail reflection
? measurements of the orbital environment"
There is NOTHING in these criteria that says that a satellite operating in
the amateur satellite service MUST carry a communications transponder
capable of relaying communications from ground stations. That is but ONE
allowable operation, but NOT the only one. This may or may not fit your
perception of the amateur satellite service, but that is of little matter
since the rules very clearly allow other uses. Read the rules.

Cube sats are about as worthless to the ham op as turn signals are on our

the ones in the past or did they really learn anything. beep beep beep

Subject: [amsat-bb] AO-7 V/A Transponder (Mode A)
Operational linear transponder satellites have dwindled to only two: VO-52
and AO-7. The latter, now 37 years old, spends approximately half its
operating time on the V/A transponder, or what we used to call Mode A:
145.85-145.95 MHz uplink, 29.4-29.5 MHz downlink.
Unfortunately, activiity on the V/A transponder is quite low compared with
what it was in the 1970s. Today, as then, much of this problem can be
attributed to the V/A transponder's relatively weak downlink signal. In the
1970s, however, many users were able to solve this problem and work DX through
this transponder out to nearly 8,000 km.
How did they do it? As one of those 1970s users, I'll tell you: low-noise
preamplifiers and good 10-meter antennas. In 2011, most modern radios have
enough sensitivity that an external 29 MHz preamplifier should not be
required. That leaves the antenna. Most satellite users wouldn't think of
operating Mode U/V without good antennas. The 29 MHz band is no different.
As any successful 1970s Mode A user can attest, a good 10-meter beam is by
far the best choice. For best results, it should be pointed at the horizon,
not elevated. Why? For most users at temperate zone latitudes, AO-7's
elevation angle will be 10 degrees or less about half the time it is in range,
and 30 degrees or more only about 10% of the time. During that 10%, the
inverse-square law of distance will keep signals strong despite AO-7 being
outside the beam's major lobe..
As in HF operation, the beam should be mounted as high above ground as
possible. My friend Ben, W2BXA (now SK), with his beam at 20 meters, was
able[
to work stations up to 300 km farther away than I could with mine at only 10
meters. That is a large part of the reason why Ben held Satellite DXCC No.
1 while mine is No. 13.
If you cannot put up a beam, a rotary dipole is perhaps the next best
choice, again mounted as high as possible. If you cannot do that either,
try a
ground plane antenna, mounted so as to be clear of all obstructions. No
matter what your specific circumstances, put up the best 10-meter antenna you
can.
Let's use and enjoy BOTH transponders of AO-7!

Content-Type: text/plain; charset="utf-8"
Hi All,
Thanks for the QSOs today during our trip to EN75. We are on a brief family
getaway and we are staying at a cabin right on the shores of Lake Huron (or
as I said early this morning on SO50, ?we are on the lake of shores Huron?).
It is very cold, windy, and a little snowy right now, so I am uncertain
about what passes I will be on.
I got off of SO50 a bit ago around 2200z, and I apologize for those that
were calling when I disappeared. I was shooting through trees and I
completely lost the downlink all of the sudden. I am planning to work from
this grid again tomorrow morning on SO50, and hopefully tomorrow afternoon
on AO27 and SO50. If you need EN75 those will be the best times to look for
me. Do keep in mind that these are only *possibilities* as I brought the
equipment along as a secondary activity. We will be returning home Saturday.
I will say that this trip has not provided as many operating opportunities
since AO51 is down. Portable operators are really going to miss this bird
since AO27 and SO50 are the main players now, but at least we do have those
two.
As a side note, if KD8BIN is on this reflector, please email me off list.
73!

I don't know what kind of problem you have and why you make such crude
and false presences.
What is so wrong when we are saying that we (the AMSAT-DL members and
BOD) want to build and fly another "AMSAT P3-E" rather than a CubeSat?
Should we scrap P3-E for the sake of another CubeSat??
Neither does the AMSAT-DL BOD nor does our membership condemn or
disapprove CubeSats.
In the past years we had CubeSat team from German Universities coming to
our Symposium.
We have even given advice to some of them or help *if wanted*. We also
attended a critical design review of SwissCube, etc..
I was personally at the CubeSat laboratory of the University of Tokyo a
couple of years ago to see some of their first CubeSats and discuss some
ideas with the Students and their Professor.
We have simply decided to concentrate our efforts to what is more
important for our community.
If you would have listen *carefuly* and not blinded by rage to what I
have said during the AMSAT-UK Colloquium, you would not make repeatedly
such statements...

I too attended the Hackerspace workshop and was surprised to see the
attendees. NASA, Universities, Hams, Students, enthusiasts, and a private
satellite company (don't remember which one). Better get on board the
Cubesat train or get left behind. Bob's mantra is "better to have something
ready to fly that works than wait for the perfect satellite on the perfect
mission." I was proud when Bob touted the value of the Ham community and how
their resources/guidance can be utilized and when he recognized the value of
simple can be better.
I teach High School students that are interested in Ham radio and space
communications and collaborate with University folks in Kentucky. They want
to work with the Ham community and want to learn, but aren't interested in
chasing grid squares. They want to find out things such as if their antenna
deployment system works in space, if their communication system works, etc,
etc. Most are intimidated and driven away by the voice exchanges on the
birds, some are interested, but most are tinkerers like ourselves. I would
encourage AMSAT members to work with the Universities and K-12 students as
they are good folks with good intentions. Make a good impression though
because they don't need us to fly their birds, but certainly could use help
and guidance. Just keep in mind many are students and are still learning as
such, so be patient with them. :-) It may take you some time to gain their
trust, but once you do, you may be surprised at how much they will work
with you and how you will be revered by them.?

Hi Peter,
Thanks for responding. I am amazed by your reaction to a simple post.
Calling it "crude, false, blinded by rage" is quite a statement. But
hey, you have every right to your opinion!
Now then, please help me and others understand your comments you made
at AMSAT-UK (listed below):
"The amateur community in general is not interested in Cubesats,
"I know some of you might not like to hear that
"It might sound like a high nose attitude, but it is life
"Those that have done P3 satellites have no interest in Cubesats
If those statements, which by the way come directly from the AMSAT-UK
video of your presentation (available online) are made by the
president of AMSAT-DL at an international meeting, I certainly do not
call this an endorsement but rather a denouncement of AMSAT-DL's
interest in cubesats.
If you call this "crude, false and blinded by rage"... I am not sure
what your talking about and it certainly does not help or aid in the
discussion.
The simple basic fact is that AMSAT-DL under your leadership is not
building, designing or planning any CubeSat projects (as far as I
know). Now, please prove me wrong. I would love to support
(financially) an AMSAT-DL Cubesat mission.

Hi, Andy!

Absolutely required is the capability of turning off the transmitter. See
RR 22.1 and RR 25.11.
RR 22.1 Space stations shall be fitted with devices to ensure immediate
cessation of
their radio emissions by telecommand, whenever such cessation is required
under the provisions
of these Regulations.
RR 25.11 Administrations authorizing space stations in the amateur-satellite
service
shall ensure that sufficient earth command stations are established before
launch to ensure that
any harmful interference caused by emissions from a station in the
amateur-satellite service can
be terminated immediately (see No. 22.1).
I hope this helps.

In the long term view, inclusion and support of cubesats into our community
will benefit all the AMSATs more than derision and ridicule has to this
point. Several cubes have attempted or will attempt to support amateur
two-way packages, i.e. DO-64, CO-65, PWsat, FunCube, UKube, Fox. Let's
encourage that, and stop with the self-centered view of the service.

Anyone else feel the need for a moderated list?
