Hello all,
I have a video recording of Lance Ginner's banquet keynote talk
(K6SSJ, of the early OSCAR days). While the lighting (of Lance) is
bad, the audio is good and the slides (all of historical photos) are
quite visible. It was captured on a FlipHD camera: 720p, 60 fps from
the "front row".
Here's the catch - the file is about 3 gigabytes. I would like to get
this on YouTube, but right now I'm short on time cycles. The next
option I'm leaning towards is Bit Torrent, as long as others would be
willing to seed it with me - at least until we get it on YouTube.
If someone is willing to help either transcode, edit, upload, etc.
this video, please _CONTACT ME OFF LIST_. This is a great historical
asset to AMSAT and Project OSCAR, and I think it should be shared with
everyone/anyone.
73,
Dave

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 ?

William,
you have a good point there, that needs some discussion indeed.
Actually I do support the participation of radio amateurs in this kind
of scientific effort. I find it very interesting and I am willing to
spend some time and even money on it.
However, I am frequently quite frustrated because these projects are
often not well documented. So me and many others waste a lot of time
just by finding out the signal parameters, modulation, how to decode, etc.
It is often difficult to find TLEs and up-to-date information about the
project and the status of the satellite.
I think some of the project teams should pay more attention to provide
as accurate as possible information and documentation to the amateur
radio community. They have endless opportunities for that on the internet.
Cheers
Edgar

I couldnt find the details about how they are going to capture data. Is it
by Hams manually capturing files and then emailing them in?
At first blush one would consider having all the APRS ground statis be
IGates and send it all in, but that will not work, because the APRS Internet
system (APRS-IS) filters out all dupes and only forwrds one copy. So when
20 statiosn receive the same thing (desired for this experiment) only one
copy makes it through the internet.
Maybe they have a different plan...
But otherwise an interesting expriment.

I was just on 145.825 MHz for the 76 degree elevation pass over Chicago. I
noticed some subjective observations I could describe as the downlink seemed
weaker than usual for a portion of the pass.
This dear reader will continue to try to determine what kind of signal
report will be most helpful for the experiment. It sounds interesting and I
already have the equipment set up.

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.
