Everyone,
If you receive a SSTV picture, I encourage you to upload the image
to the ARISS SSTV gallery at
http://www.amsat.org/amsat/ariss/SSTV/
so that everyone can see it. And, if you have not seen any of the images
yet, go there and be amazed. There are actual images from ARISSat's
cameras showing views of the Earth from orbit. There's also two images
of the cosmonauts taken by ARISSat's cameras during ARISSat-1's
deployment.

Oh - so you mis-spoke. Apology accepted.
But still - even without ASISSat-1 on April 12, there was plenty to teach
and plenty to learn.
And even with yesterday's deployment delay and 440 antenna whip "lost in
space," I stand
by my earlier post: If you cannot find something positive to teach about
space and ARISSat-1
and ham radio from what occurred yesterday then you need to find another
hobby.

Hi All,
I believe we now have some TLEs for ARISSAT-1
It is catalogue number 37772 and referred to as Radioskaf-b
Approx 20 secs ahead of the space station at this time and appears to still
be less than 1 kilometre below

THANK YOU for those kind words. From a technical standpoint, it was
gruesome. Never did I ever
have my earpiece audio match the live video ... same with Gordon West
mid-way through ... I never
knew if my slides were up ... I saw some of what I had said twenty seconds
beforehand come on
as "live" on my monitor ... and when the cut to Leo LaPorte himself was
flawed, I can only imagine
the blood pressures rising in Petaluma - where his new studio is.
And the firm we were using the past week for handling audio/video from
interviewees was, well,
"dismissed." It was a madhouse "behind the scenes." But Leo's people are
changing services

Anybody have any idea when new TLEs will be available for ARISSAT? I would
think it has to be some Distance from the ISS by now.

Yes! It is something that should be asked. We know from the so called test
and the Yuris Night deal that the bird was used in ways not previously
known. So either the antenna broke off or was not attached. This was not the
crew that would have deployed in February. As has been said before beggers
can't be choosers. If interested people pony up the bucks we can build and
pay to launch anything and be autonomous. The reality is that raising
several million dollars is not going to happen. So we take what we can get
for now and celebrate the good as best we can. ARISSAT from my understanding
was always what it is an education sat. The fact it has a transpoonder was a
nice add on thanks to SDR and a test for the Fox platform. It was not
advertised as an amateur only bird.

Phil, let me start by saying that I hold in the highest respect for all
you've done for Amateur radio, and digital communications in particular.
I appreciate your foresight in many areas, and rooted for you even when
other people were griping about "That Crap Phil Is Pushing".
I've been involved in Amateur Radio for almost 50 years, so I'm no rank
beginner, and I've been employed in the Aerospace industry for the last
30 years. I've BUILT satellite components, and integrated them into
spacecraft. Some of the Really Neat Things I built at Hughes Aircraft
are still up there. For the last 7 years I've been employed by a company
that launches satellites to GTO, and I'm extremely familiar with
everything that goes into getting the customer's package into space.
We joke about "The rocket won't lift-off until the stack of paperwork is
as high as the payload fairing".
This deployment was NOT done properly. To call it the rousing "success"
that some are trumpeting out here is wrong.
A fully functional spacecraft was delivered to the launch service, and
they screwed up.
A important part of the spacecraft was damaged, and the attitude was
"Gee, it had another antenna thing on it? Well, we don't know what
happened to it, and we really don't care, as this toy is interfering
with our real work".
If this was such a now-or-never deployment because of the limited life
of the batteries, then the deployment should have been carried out to
the letter. To hear that nobody knows (or admits) what level of training
the crew had is very disturbing.
To hear what amounts to "Don't worry, it was designed to be idiot-proof"
is also disturbing as it clearly was not.
If "things" had to be attached to the spacecraft before deployment,
there should have been a concise, detailed checklist, and the stowage of
those items should also have been handled with care so they didn't get
"lost".
I'm happy that it appears to be working, as I know a lot of sweat went
into it. Everybody involved, except the ISS crew that deployed it,
deserve a hearty pat on the back.
And as far as using a satellite to communicate with people "That could
be done much more easily over the Internet" misses the whole point.
We're trying to get young people involved with Amateur RADIO; they
already qualify as Internet Experts.
The allure to many young people is being able to do this *without*
wires, and an ISP, and a monthly bill.
A piece of wire is just a wire, but radio is magic. It's what made it
appealing to me 50 years ago, and a lot of other people, too.
And if the radio just happens to be whizzing by 250 miles above you,
that adds to the magic.
I apologize if I came across as a bit cranky in my first few posts, but
having "Ben There, Done That" with space hardware, I couldn't believe
what I was hearing and reading.
These guys wouldn't last 30 days in a real company.
If they worked for Elon Musk, they probably wouldn't last 30 minutes.....

That really is a hoot.
I've stayed away from commenting on this because I disagree with the entire
program effort...but the comment you and others have made about "perfect"
vrs "absolutely perfect"...drew me in.
With the current issue of the "bird" we are not talking about the difference
between perfect and almost perfect we are talking about a major error
(tossing without the antenna on) which has deleted significant payload
capability.
It is reasonable to ask "why this happened".

I noticed in the NASA TV commentary that ARISSat was constantly being
referred to as an "educational" satellite with scarcely a mention of its
amateur radio capabilities. AMSAT was named just in passing as being one of
the parties involved with its design and construction, but that was about it.
At least one other website also emphasized that ARISSat was built for
educational purposes, which disappointed me as I was always under the
impression that ARISSat was primarily an amateur radio bird.

The signal levels from ARISSat-1 should be similar to those expected from
the AMSAT-UK FUNcube-1 satellite (and also from UKube-1) and the AMSAT-UK
team are keen to discover what will be the minimum and best type of antennas
for schools to use.
To encourage everyone to receive and report the ARISSat-1 145.920 MHz BPSK
