Hi AMSATs,
I really wonder if this ever can and will be launched.
AMSAT started with eperimental communication systems on the early oscars,
and grown into highly complex satellites like AO-40, which was a real
achievement for ham radio amateurs. However recent years there is a big
trend on CubeSats, of which most are bleep-sats as they only send digital
data (as cheap downlink ?). Luckily not all CubeSats are like that :o)?
At least these CubeSats are under some kind of control, and don't survive
very long or can be switched off to minimize RF polution.
When I see the idea of 100 chipsats that will all send digital RF signals I
wonder where amateur satellite hobby will go into.
I see these ChipSats more like RF polution and I believe you can better put
your money and effort in designing a real communication satellite.
I wonder what is the mission of these 100 chips ? (commercial ? publicity ?)
Is there any technology thing we learn from this ?

Andy Thomas G0SFJ posted a great web page for a vintage Russian
geostationary satellite locator he was fortunate enough to buy at a flea
market. I modified a program of mine to use the old school Russian IMMARSAT
map as the basis for a polar projection satellite tracker.
I am sure there are many other programs out there that do the same thing.
Here are a few screen shots from yet another one. Even though the continents
look a little funky the tracks actually came out quite close to SatPC32
tracks. It does take a little while to get used to the new look of the
world. It is an equiangular projection so as you get farther away from the
north pole things look larger. Who knew Australia was so large.

William, I have wondered about this, too.
I have come to think of these as seeds. Seeds that plant the idea of
satellites in the heads of people and make them want larger, better
(heo) systems.
They won't last that long, so the idea of RF pollution isn't really
there. And, if the sat sub-band can have a section devoted to these
cube sats such that they aren't everywhere, even better.
The more people that get a taste of satellites, the better.

I think it will be a great acheivement to successfully deploy sats this
small and successfully receive data from them.
I do, however, share your concerns regarding long term RF pollution. In the
case of KickSat this would be mitigated by the short lifetime before
re-entry of a few days and I understand the total bandwidth occupied by all
the 10 milliwatt ChipSat transmitters will be under 100 kHz.
KickSat is not a problem but you can see how this technology can be built on
in the future. Low cost swarms of satellitess can be a valuable scientific
tool. When it moves to the commercial arena we won't want it in our bands.
The QB50 project https://www.qb50.eu/ is proposing to launch a swarm of 50
2U CubeSats, see AMSAT-UK Colloquium presentation at
http://www.batc.tv/vod/QB50.flv
QB50 will have a significant spectrum requirement.
I note that in the USA the NTIA is considering a paper proposing 10 MHz of
UHF spectrum for small satellites, see
http://www.uk.amsat.org/2011/10/01/new-itu-service-for-cubesats-and-nanosats/
Maybe that could be a solution to be problem ?
Now you could say that if there's 10 MHz of spectrum between 400-2025 MHz
going spare then the Amateur and Amateur Satellite Services could do with it
;-)
The worrying thing is that some may consider our spectrum might fit the bill
:-(

Patrick,
Just made a contact with 4C1JPG on AO-51 around 2218 on a 70 degree pass
here in northern CA. They had a good signal into AO-51.
There were several other contacts made with 4C1JPG on that pass.

Hi!
I saw this on another mailing list, and haven't seen any mention
f it anywhere else, so here goes.... Members of the "Radio
xperimentadores de Occidente" radio club XE1TD will use the special
exican call 4C1JPG during the 2011 Pan-American Games, currently
aking place in Guadalajara. 4C1JPG ("Juegos Panamericanos
uadalajara", the Spanish translation of the event in that Mexican
ity) will be on 160m through 6m, as well as the satelltes through
0 October 2011.
QSL cards will be available, as well as electronic confirmations in
oth LOTW and eQSL. More information about 4C1JPG, including the
exican address of the 4C1JPG QSL manager, is available at:
http://www.qrz.com/db/4C1JPG
By the way, for those who work that station - or any Mexican
tation - and would like to send SASEs instead of including a
S dollar bill or IRC with your QSL request, I have lots of
exican postage stamps. Using SASEs works a lot better when
rying to send something to a Mexican ham. Please e-mail me
irectly if you would like to get some stamps for QSLing.
Good luck and 73!

This morning I initially used the lastest Keps for Object B and was able
to copy the CW telemetry, however, at Object B's LOS, I was still
copying the signal. I switched to Object D and was able to copy CW for
another minute or so before LOS which corresponded with the Object D

for SRMVU.
The telemetry I copied was SRMVU C Z Z P C C at EN91ck for the 0043UTC

Hi Carl,
The other day I reported the same observations to the SRMVU team---my
use of Object D is my best guess for this bird---based on LOS as you
have seen. So, what I am seeing matches what you are seeing!

Wasn't that a fun day? All those Scout troops working the FM satellites ...
It was GREAT!

Hi!
After receiving a few comments to my post last week about my
trip to the hamfest in Tucson on Saturday (22 October), I have
decided to go to the DM51bx/DM52ba grid boundary in southeastern
Arizona after the hamfest. I should be there in time for the
following passes:
AO-51 2133 UTC
AO-27 2147 UTC
AO- 7 2220 UTC (should be in mode B for this pass)
AO-51 2310 UTC
Depending on when the hamfest wraps up in the morning, I *may* be
able to get out to the grid boundary in time for the AO-27 pass at
approximately 2007 UTC. No guarantees on that. I will run APRS as
WD9EWK-9 while on the road after the hamfest. You will be able to
see my location at http://aprs.fi/wd9ewk-9 among other places on
the net.
For the AO-7 pass, I tend to park around 145.960 MHz +/-. If I am
not working anyone there, I will tune around and try to call anyone
else who may be on the pass. I will miss not having FO-29 to work
on this trip, but this AO-7 pass should cover most of North America
for those wanting to work me in SSB.
As with my other trips, and also for the hamfest passes Saturday
morning, I will be happy to send out QSL cards. There's no need
to first mail me a card - just e-mail me with the QSO details.
If you're in the log, I will drop a card in the mail. I will also
upload all QSOs to the Logbook of the World system, once I am back
home.
73!

The A#1 Killer AP is something we have tried twice on short li=ved missions
and which we already have ready for our next mission, (but no launch
opportunities) is a PSK-31 transponder.! It is really more than you first
think: Please see:
http://aprs.org/psk31uplink.html
1) Normal HF PSK-31 uplinks on 10 meters where the Doppler is 14 times less
than on the typical UHF downlink.
2) VHF or UHF *FM* downlink. Notice FM. This means what EVERYONE see's on
their waterfall is EXACTLY whateveryone else sees. Thus, everyone just
jumps into the 3 KHz FM audio bandwidth wherever they see an empty spot and
then can even see THEMSELVES full duplex because they are transmitting
linear PSK-31 on the uplink on 28.120 while simultaneously seeing what
everyone else is seeing on the VHF or UHF FM downlink.
3) Because you see what every one else sees, including yourself, you can SEE
your good signal or your bad signal, AND you see how you are shifiting in
Doppler and can correct for it.
4) AND because it is full duplex, you TX the entire pass in a steady stream
while looking for QSOs in the downlink. We could have 20 to 30
SIMULTANEOUSE QSO's going on at the same time and even be talking to all at
the same time.
It is the ULTIMATE satellite transponder, because:
1) Full duplex
2) Minimal Doppler
3) You correct for your own Doppler
4) 20 to 30 simultaneous users
5) Free software, no hardware!
6) Vertical 10m antennas are IDEAL power-levelers. When overhead (and 10 dB
closer) the signal arrives at the satellite 6 to 10 dB down due to the
vertical antenna pattern.
It's a win-win-win mission. Our attempt failed on PCSAT2 due to a broken
antenna (pre-launch integrators and astronaut handling) and our attempt on
RAFT failed due to not enough time available for the tests due to mission
conflicts during a shor 5 month mission.
Please someone do this. It is TRIVIAL to do. Just combhine a 28.120 PSK-31
receiver and a VHF or UHF FM transmitter. Done.
