Hello Ignacio,
I am sorry to learn that LO-19 has stopped sending CW telemetry.
You might look at: http://oscar.dcarr.org/
There DF2LV reported hearing LO-19 telemetry on Oct-23-2009 between
10:46-11:00 UTC.
Perhaps DF2LV can comment on any frequency drift issues? I think that
report is the last report of hearing LO-19. He appears to be a regular
listener to LO-19, according to the log at http://oscar.dcarr.org/
Best wishes for a speedy recovery for LO-19!

Afternoon,
There have been some changes of the Space Track designation for SO-67
recently. Originally, it was object 35867. According to the AMSAT-SA page,
it is now object 35870, with the old 35867 now FRIGATE/IRIS according to
Space Track. This is reflected in the AMATEUR.TXT list most tracking
programs use. If you use the AMSATNAMES.TXT file in SATPC32, you will need
to make the appropriate change.
Of course, this assumes that NORAD is fixing a mistake and not introducing
one. ;)

Hi, amsat-bb,
With regard to the very interesting subject of Antennas in Space (in
general), I hope some of you will be interested to plan to take up a
design for a spaceborne antenna, sounds interesting! To help in that
process, I was very impressed to read (well, the non-technical bits!)
of the DESCANSO book :
http://descanso.jpl.nasa.gov/Monograph/series8/Descanso8_00_thru_acronyms.pdf
There are a wealth of information derived from JPL missions that I
believe we could take advantage of in the next 20 years of AMSAT
design projects.. other books in the series have a lot of information,
and who knows - a Mars project might not be that far off if we look at
it in a pragmatic way: small payloads will be sent to Mars for
validating a lot of the systems before Humans can go, and the Hams +
Amsat projects + Space Geeks + Space missions = public support =
public funding support formula is hard to ignore... IMHO
So, why not start a individual track on amsat-bb with a prefix [Phase
5] in the subject header, so that others who are not interested, for
now, can tune out.
Any ground rules ? Any publications we can get started on that would
add to a scholarly discussion on Phase 5 mission planning.

best signal in both AZ and EL. Sort of a poor mans monopulse system. This
works OK for antennas in the microwave region but would not work to well for
VHF/UHF low gain arrays. What might work well is to use a pair of antennas
with a "doppler scan" circuit that steered the rotor toward the estimated

Alan,
Thanks for the info. I have been trying unsuccessfully to access the
satellite on the last 2 passes.
The times differed a little from the email and I went by the tracking
program. SatPC32 was the one I was using.
I heard nothing. I was hoping to at least hear my own down link
signal. I had good foot print
for Alaska and Western Canada as per the email that said it would be open.
I am looking forward to work this satellite. Congrats to the folks
AMSAT-SA and students that put this
this bird up.
73,
Dale - KL7XJ
I am looking forward to work this new satellite. Congrat

Those of you who have seen my post to this forum in the past know that
I've unfortunately had to sell some of my gear on and off to make ends
meet. I went from a TS-2000X to an IC-820 to no satellite stuff at all.
Just recently I had to part with my HF rig as well.
I was determined though that I wasn't going to give up and an FM LEO
capable station seemed feasible and better than not having anything at
all so I have started pursuing it.
I just got my Yaesu VX-3R HT from the UPS man Friday, it is primarily to
be my receive radio as I already have another 2 meter radio.
I have felt like a kid who couldn't play with his new toy though
because my adapter to be able to hook up an external antenna to the SMA
connector on the HT was back ordered. We have a few repeaters here but
I'm out in the sticks and the rubber ducks on these little rigs are
notoriously dreadful.
Anyway finally decided to step outside the house tonight about the 1800
UTC pass of AO-51 and see if I could hear anything but noise.
Amazingly enough, even with just the stock rubber duck, I could hear
stations. Everything was down in the noise and not really discernible
enough to copy but I could tell people were there.
I don't think I really needed much more antenna and I probably would
have had decent copy.
It was only a small step and there is much work to do but it did make me
feel as if I had actually moved forward on getting back on the birds.
Just wanted to share,
73,

Hi Alan,
Originally SUMBANDILA was and is object 35870 and has been changed
designation for SO-67,
FRIGATE/IRIS was and is object 35867.
Nothing is changed!
My keps are correct.

Hi folks,
Just curious...
One of the ways to make a circularly polarized antenna is to feed two
linearly polarized antennas in-phase, but mount one them 90 degrees rotated
from the other, and 1/4 wavelength ahead of it.
Couldn't one also mount the two antennas 180 degrees rotated and 1/2
wavelength ahead?
The reason I ask is that I have some flat panel 2.4 ghz "Wi-Fi" antennas,
and the mounting holes work out best that way.
The only effect I can think of is that the array will probably pick up
signals from both left and right polarizations, which could actually be handy.

Above link has a wonderful 3D graphic display of waves. Give it a try.
You can adjust V, H, phase, and then display sum of the 2 waves.
I use it mainly to show how circular polarization comes about.
The sum of 2 waves in the same plane ( 180 degrees rotated ), 180 degrees
out of phase ( 1/2 wavelength ) is a nul which probably would be out
performed by a rubber ducky.

Content-Type: text/plain; charset=ISO-8859-1
Over the last couple of months I've ported the Plan13 satellite
tracking algorithm to a library for the Arduino platform. To inspire
Arduino hobbyists and fellow amsaters, I've made a website to explain
and explore this material, http://sites.google.com/site/qrptracker/
There you'll find a 4 min. introductory video. Around 1:33, the
Arduino demo starts.
Though I was originally thinking of making a sort of doppler tuning
dongle for my FT-817 -- a sort of LVBTracker for the trail -- along
the way I've become aware that there are many uses of a $4 device that
can track 13 tles all alone, and leave about 14kB for other
programming, all with the possibility of average power use in the tens
or hundreds of microwatts and SMD dimensions of 8mm^2.
For instance, equipped with a low-power tracker like this, an amateur
satellite could track its own location over the earth by means of a
reliable real time clock, and it could change its mode depending on
its calculated location, say turning off its beacon over the poles and
oceans. (Plan13 *in* outer space!)
I've implemented this idea in the demo
http://code.google.com/p/qrptracker/source/browse/trunk/modeSwitcher_powersave
.pde
Regions of earth, defined with latitude and longitude limits, are
stored as an array, and when Plan13 finds the satellite is within
one of these regions, it raises one of its pins to a 'high' state,
otherwise, this pin is 'low'. When not calculating position, the
AtMega328 can drop into a low-power sleep, consuming around 20
microWatts, but retaining the state of its signaling pin. The
satellite uses the state of the pin to turn off its beacon, or to
switch from a linear to an FM mode. I plan to illustrate this in a
future screencast.
Of course, the same idea could be implemented in a multitasking IHU of
any platform. qrpTracker is offered as a simple means by which people
can play around with satellite tracking in microcontrollers, and I
welcome collaborators and bug reports at its open-source code
repository at http://code.google.com/p/qrptracker/
Finally, if anyone has use of a chip that spits out AZ/EL and doppler
info, either through serial-line requests or off of the I2C bus, I'd
be happy to send off a chip loaded with the keps you need. Your
application would have to supply the real time clock, and eventually
the loaded keps would get stale, but by that time you'll be hooked and
have the equipment to update the keps yourself :-)

with decoder and coefficients file can be downloaded from here:
http://www.dk3wn.info/files/ao51wod.zip
The AO-51 telemetry archive is on the AMSAT FTP server. DK3WN's new
decoder is for processing "raw" WOD telemetry files. For example, the
WOD data collected for October 2009 is here:
ftp://ftp.amsat.org/pub/amsat/telemetry/ao51/2009WOD/Oct2009/raw1009/
The decoder generates a .CSV (comma separated) file that can be opened
in Excel, etc. A nice feature is that the telemetry program actually
graphs the data, too!
THANKS, Mike DK3WN!

AMSAT's OSCAR Number Coordinator Bill Tynan, W3XO announced he has
received an e-mail sent to the AMSAT-NA Board of Directors by Hans
van de Groenendaal, ZS6AKV, Secretary SA AMSAT requesting that an
OSCAR number be allocated to SumbandilaSat.
In the e-mail Hans states that the amateur radio transponder on
SumbandilaSat was successfully switched on from the ground by ZS6BPZ
during the test phase on Sunday 18 October 2009 and that several QSOs
were made through the transponder.
The amateur radio payload on SumbandilaSat was developed by SA AMSAT
and incorporated by the University of Stellenbosch into the main pay-
load. The SA AMSAT payload was officially coordinated through the
IARU Satellite Frequency Coordination Panel with an uplink of 145.880
and downlink of 435.350 MHz
Bill replied, "Therefore, by the authority vested in me by the
AMSAT-NA President, I hereby designate this latest amateur radio
satellite as SumbandilaSat Oscar 67 or SO-67. On behalf of AMSAT-NA
and the world's amateur radio satellite community I congratulate those
responsible for building, testing and launching this new satellite.
May it have a long and successful life."
You can hear more of these initial and QSO's through this new South
African ham radio satellite at:

Australia's Swinburne University, together with EM Software and
Systems, has developed an online tool that will allow users to
calculate exclusion zones around antennas where radiation levels
exceed safety standard limits.
Commissioned by the Australian Communications and Media Authority,
the exclusion zone calculator will allow people to conduct safety
assessments of transmitting antennas, such as those found on boats,
four wheel drives, at fixed station locations and even communication
networks operating in the VHF and UHF spectrum. This includes ham
bands from 2 meters on up through 2.4 GHz.
To calculate the zone, all users need to do is enter the antenna
type, transmitter power, antenna gain and frequency band into the
online tool. Click your mouse and the program will automatically
calculate the safe distance around the antenna in metric distance.
The ACMA has also produced a booklet entitled Human Exposure to
Radio Frequency Electromagnetic Radiation Information for Licensees
of Radio-Communications Transmitters. Both the on-line tool and
a booklet that explains EME health exposure can be found at:

The SouthGate Amateur Radio News Site and Amateur Radio Newsline
reported this week there is a possibility that Iran's Mesbah-2
satellite, slated for launch early 2010, could operate on frequencies
allocated to the Amateur Satellite Service.
An on-line report at astronautix.com says that the original Mesbah
satellite, lost in a 2005 launch failure, was to have operated on
Amateur Satellite Service frequencies. Now its being reported that
Iran's Minister of Communications and Information Technology, Reza
Taqipour, has said that the replacement Mesbah satellite has success-
fully completed pre-launch tests and is now ready for liftoff early
next year.
Most observers think that there will be little difference between
the transponder set-up between the lost Mesbah satellite on the new
replacement bird. See: http://www.astronautix.com/craft/mesbah2.htm

as
well. Scouts also took part in a Jamboree on the Internet (JOTI) activity.
Approximately 400 Scouts, parents and officials attended the event.
6. NASA Reports on ARISS Contact
NASA posted as one of its ?Daily Top Stories? an article from the Vancouver
Sun
about the October 9 Amateur Radio on the International Space Station (ARISS)
contact with Belmont Elementary School:
Hundreds Of Students "Enthralled" Talking To ISS Astronaut. The Vancouver Sun
(10/10, 178K) reported, "Canadian astronaut Robert Thirsk zipped through the
heavens above Langley's Ecole Belmont elementary school Friday, riding the
International Space Station and chatting with 533 enthralled students." The
event was organized by "ARISS (Amateur Radio International Space Station), a
NASA- sponsored educational outreach program." According to the article,
"Judging by the reaction of the children sitting cross-legged in the gym, the
program was an obvious hit."
