Bob, Politicians are the same the world over.
I note that some of your Politicians seem paranoid about the USA's biggest
trading partner, Beijing. I don't mind betting that in a few years time your
Politicians will be falling over themselves to vote billions of tax dollars
to the Space program to prevent the US falling into 3rd place behind the
Russian Federation and Beijing.

I thought the members of the list would be glad to read the following
from Bob, WB4SON, written on the funcube list:
"Guys I keep reading false rumors here about big-guns or high power
needed to access ARISSAT. That is NOT correct. I had no issue hearing
my signal on the downlink. I'm using omnidirectional low gain antennas
(egg beaters) and 5 watts produced a S8 signal that was at least 5 S
units above the noise. I have NO doubt 1 watt will produce a fine
downlink signal
What did or did not happen during the launch makes no difference now
as it is working fantastically well
Try it. Enjoy it. No worries!!!"

The satellite is operating under a Russian license, so I assume the FCC
would have no jurisdiction over it.
In any event, the fact that the transponder seems to work well indicates
that the spacecraft should have no trouble hearing commands.

It's longstanding tradition to give a spacecraft a pre-launch name and
then assign it another once it successfully reaches orbit. To minimize
the confusion, the pre-launch name usually ends with a letter from a
sequence while the orbital name ends with a sequential number.
This tradition dates from the days when launch vehicles were rather
unreliable and many spacecraft didn't make it to space. Thus holes in
the numerical sequence were avoided.
E.g., the weather satellite NOAA-E became NOAA-8 when launched in 1983.
Phase 3-B became AMSAT-Oscar-10 when it was launched in 1983. Phase 3-D
became AMSAT-Oscar-40, and so on. But Phase 3-A, which was lost in the
launch failure of Ariane L-02 in 1980, never received an Oscar number
because it did not reach orbit.
We do seem to have a lot of names for this one. So far we have:
ARISSat-1
[i.e., Amateur Radio on the International Space station, Satellite #1]
RadioSKAF-B (????? ????-B)
Cedar (????)
Does anyone know if it'll also get an Oscar number?

The radio regulations govern here. Both the USA and Russian administrations
are signatory parties, along with about all others around the world.
The pertinent provision is:
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.
This applies to all space stations in all radio communication services.
More information on this topic is at Controlling Satellites on the IARU web
site.
Responsibility for the space station lies with the authorizing administration.
I hope this helps.

I just downloaded the Celestrak keps and Radiskaf-B is in the list when you
scroll all the way down.
It doesn't show up when one selects the AMSAT keps.

Hi satelliters,
Delighted to see on the satus page http://oscar.dcarr.org/?that the
transponder
is working.
Congratulations to everyone involved.
What was the problem/fix for the antenna problem that delayed the launch to
later in the spacewalk.
Can't find anything new on the amsat.org web site

Americans built the spacecraft BUS. That's most of the spacecraft, but
not all of it. It is also carrying a scientific experiment built by
Russian university students. This is a highly significant part of the
spacecraft in that it formed much of the justification for the Russians
to agree to launch it.
And no, I don't consider the launch of a satellite equivalent to a trip
on a container ship. Value-wise, even a launch to LEO is literally worth
its weight in gold. It is an extremely valuable service and one well
worth some delays, inconveniences -- and bumps -- to get.

I add it was against through all patronizing commenting when they first show
up their protoboard model with jumping wires, I still remember
some making jokes about it...
He's up and running fine with a back up transponder in bonus!

As per my and other linear transponder test signal pass through but they are
not too strong even if some report seems to confirm 1 watt
power their EIRP is unknown assuming the command channel is on UHF but you
know the word "assume" definition:)

I try to decoded the last 30deg pass this morning but no luck even if the
blue marker remain steady on the CW bump nothing "lock" as far i
can tell any QRM or QRN seems to hold the lock process and on VHF here i
have some intermod... living about half a mile from a cell/paget
tower?
