Anyone put together software to decode the XW-1 beacon yet?
Sorry if someone already mentioned .. Still reading thru my emails..
Lots of TTT .. Is that normal?
Oh and is china interested in emails with received telemetry?

Good question... I was into radio astronomy long before we had PC's, but I'm
assuming
(perhaps wrongly) that the easiest method to track a planet (for a short
time) would be to use
current right ascension and declination data and a motorized polar mount,
i.e. a telescope mount
with antennas.

Hi,
This is the second time that I tried to listen to RS-22... but nothing
heard over eastern Canada.
I tried the 13h50 UTC pass... nothing !?!?!
Any body out there have the same problem !?!?

Hi AMSATs,
After many work on my transponder design I decided to put some work in
extending my lab.
One of the things I liked to have is a vacuum test chamber, to test
electronics under vacuum conditions.
I have looked around and I see all kind of classes of vacuum pumps, and
their equal increasing price.
My question is how deep the vacuum has to be to be able to do a valide test
on (space) electronics working under space vacuum conditions ?
I also would like to know if anyone has experience in SSB mode with the new
power modules types from Mitsubishi. Like the RA60H1317M, which can give 60W
power on 2m with only 50mW input power.
I am looking for some PA behind my LE005-R2 transponder design, to get a
small sized high-power linear transponder. The transponder gives 200mW PEP,
so the 50mW is no problem at all.I just wonder how linear these Mitsubishi
modules are, when using in linear mode.
In the datasheet it says that they 'may ?lso be used for linear mouldation",
which doesn't give many guarenty. Any experience with these modules in
linear (SSB) mode are welcome.
73 de PE1RAH, William Leijenaar

It is quite a nice christmas gift for the amateur satellite community who
was offered by China. XW-1 will make possible transatlantic
contacts when he will be over central atlantic ocean. In North America the
following grids will be in range for EU contacts: FM 27-28 FN
04-05-10-12. In my grid FN36 i will have a 5 deg elevation at max and it
will be lower for the grids i mentioned.
Congratulations Alan and for all of your team. You are the proof that our
amateur satellite future will be more and more internationally
driven XW-1 and SO-67 and all the other project in the making is and will
only lead and guided the next satellite builders to redefined
their next steps.
Is a new HEO capabilities can emerge? i believe yes and it will probably
come from unexpected new launchers sources.
The global world warming effect and the greenhouse gas effect will need new
measurement tools. A strong pressure will be put on ways to
measure those greenhouse gas and satellite will be the ultimate tool. It is
a new potential where amateur radio satellite builders can
exploit? At our local level here we use the emergency communication
argument, with this global warming potential disastrous consequences at
an international scale the amateur radio community will have to shift the
usual emergency communication focus towards emergency global
warming communications.
Satellite monitoring and international greenhouse gas space watch will
represent a lot of new openings. The amateur radio satellite world-
wide network is able to handle a lot of data downlinks, data who can be
transferred through internet at any point on the earth. APRS and
DPRS is already monitoring and sending weather reports from all over the
world is a pollution index can also be transmitted aside of all
the other weather data parameters? What about a PC screen showing the global
pollutants evolution on a day by day basis live data coming
and relayed by amateur radio satellite. The possibilities are endless will
we be able to positioned ourselves accordingly???
Some will say it is fiction but what's it's call fiction today often became
tomorrow reality.

Hi Gordon, the signal SSB CW listened with your kenwood, and' that related
to the Telemetria of the new Chinese satellite XW-1.
To confirmation the decoding of the CW with signals groups TTT of 3

Wayne replies:
The SatPC32 installation includes a program called SuM.exe (Sonne und
Mond) that tracks the sun and moon. It doesn't display their visibilty

Each telemetry channel encodes a 3-character value. "TTT" represents a
telemetry value of 000, which would be normal for certain circumstances...
when the Channel 2 telemetry value is 000, it indicates that only the beacon
is operating (most of the time, for now). When the transponders are not
operating, it is normal for the telemetry channels associated with them (7 -
13) to read 000. The telemetry format can be found here:

Hope this helps!
