Boselli prize 2010 to the Amateur Radio on the International Space Sta-
tion (ARISS) program. =
The A.I.R. Board found that ARISS meets every requirement for the award, =
which is bestowed on "radio enthusiasts who promote the culture of radio, =
showing the importance of radio communications to hundreds of young stu-
dents in Italy, Europe and beyond, spreading the use of radio from the =
forefront of science in the vast outer space down to small classrooms." =

Reid, N0RC plans to operate on FM satellites from Thule, Greenland
(Grid FQ56) for one month starting March 23. Reid describes his
plans, "I will try to use satellites that uplink on VHF, because
my transmissions on UHF would interfere with the BMEWS radar on =
base. I'll need to determine if BMEWS interferes with UHF downlink =
which will affect my satellite operation."
Reid's schedule will be as work/passes/weather permits. He plans =
to primarily operate the FM satellites due to equipment limitations. =
He plans some HF operating in between passes. Look for OX3RC on the =
satellites and on HF starting March 23.
Reid concludes, "I cannot give a specific time of operation because =
my primary mission is work, and my work schedule is dependent on =
weather." Since he will not have a set operating schedule Reid will =
send out an email right before I go on the air for that time period.
Reid has setup an email list on Google Groups:

AMSAT-UK has released images of the Command, Control & Telemetry =
(CCT) board being developed for the FUNcube Amateur Radio satellite.
FUNcube is the latest satellite project being developed by AMSAT-UK
members. In addition to a telemetry beacon FUNcube will carry a 435 =
to 145 MHz linear transponder for SSB/CW operation. It will be the =
first time a satellite this small has carried such a transponder.
The CCT (Command, Control & Telemetry) Board is one of the circuit
boards being designed and made by a number of members of the AMSAT-UK
FUNcube development team. Its function is to control what the satel-
lite does in realtime:
+ Automatically switch the satellite from 'education mode' to
'amateur mode'.
+ Gather readings from more than 30 sensors on the satellite, eg:
temperatures, battery voltages, currents and encode them in a
Forward Error Correcting format for downlinking via the beacon =
transmitter.
+ Collect and store the data from the Material Science Experiment
for a whole orbit to demonstrate variations in thermal performance =
of material having different surface finishes in a vacuum and no
gravity.
+ Monitor the main battery voltage, and switch the satellite into a
low power mode if the battery voltage drops below a certain preset
level.
The board will also contain the vital circuitry to deploy the 2 metre
and 70 cms antennas after the satellite is deployed from the rocket.
The board will communicate with the rest of the satellite via the I2C =
bus.
The pictures can be seen on the FUNcube site at
http://www.FUNcube.org.uk/
FunCube frequencies for the inverting linear transponder are:
Uplink 435.080 =96 435.060 MHz
Downlink 145.960 =96 145.980 MHz
Beacon 145.955 MHz CW and BPSK =

Amateur Satellite Service frequency allocations vary worldwide
depending on your location in the ITU Regions 1, 2, or 3. This
means that some stations may not be able to operate on all of
the satellites; and conversely, if all frequency allocations
are taken into account the design of future satellites becomes
limited.

blue grids are the ones he missed. See: http://www.papays.com/nd9m.jpg
John wrote, "I've received several inquiries about the software

The program is a Great Circle Map generator with some very nice =
features created by SM3GSJ. KD8CAO originally discovered this program =
and posted info about it on the amsat-bb. It is called GcmWin."
Roger, SM3GSJ has added some functionality that makes it very suitable =
for those who chase grids. Originally, to plot grid square data, a 6 =
character grid designation was required. Roger changed it so that 4 =
character grids were acceptable. =
In addition, only one set of grid square data could be overlayed on =
the map. He graciously changed the software so that two different =
colors from two different grid square files could be plotted. Now =
you can show your confirmed grids in one color and your worked grids =
in another. The program has many other features related to propagation =
that might interest those who work HF.
The homepage for the software is: http://www.qsl.net/sm3gsj/
John is thinking about creating a webpage that could be used as a
repository for posting these maps for anyone that is interested
in having their plot on line. Let him know if you're interested.
You can view his plot at: http://www.papays.com/k8ysegrids.jpg
In that plot John set the radius at 8200 miles which is a compromise =
between detail and the maximum distance that can be worked on AO-7. =
If you decrease the radius, more detail can be shown. You can include =
grid square numbers if you make the radius small enough. Red is con-
firmed and Blue is worked. =

The planned activation of the Arecibo Dish on Amateur Radio Earth-
Moon-Earth (EME) operation was initially mentioned in ANS-045. This
article provides additional information to assist stations to pre-
pare for the Echoes of Apollo EME 2010 or World Moon Bounce Day.
Echoes of Apollo EME 2010 or World Moon Bounce Day, is scheduled
for the weekend of April 16, 17, and 18. This year, EOA has been =
graced with a special opportunity to use the Arecibo Dish as the
ultimate "big gun" station on 432 MHz SSB & CW. Arecibo has more =
than 50 dBi gain on 432 MHz so the team thinks it can be heard =
with modest equipment. A large OSCAR-class antenna array equipped =
station with low-noise figure preamps may be able to receive the
bounced signal.
Ed, KL7UW, wrote an analysis of minimum antenna requirements on the
Moon-Net e-mail reflector. Ed said, "My preliminary EME path-link =
analysis indicates that you will need more than 60 watts at Arecibo =
for the small home-built antenna/receivers to be successful (espec-
ially for SSB). My guess is that a 7-10 element yagi (12-dBi gain) =
would require use of JT-65 for reception of a 60 watt transmitter at =
Arecibo. Therefore, obtaining a high power amplifier, 1 KW or greater
for Arecibo is very important for successful SSB reception by small =
stations." =
Echoes of Apollo EME event coordinator, Pat Barthelow, AA6EG predicts
success by many small stations since he has confirmed the offer and =
availability of an SSPA producing approximately 600 watts at the out-
put connector of the amplifier for EOA Arecibo use, custom manu-
factured for this event, and future EME events, by Lionel, F1JRD of =
Freescale Semiconductor (http://www.freescale.com). Many Many thanks, =
Lionel! An SSPA 48 volt, 20A power supply has also been donated for =
use in the event, and future EME events, THANKS to the generosity =
of Andrea, IK5QLO. Diligent effort on antenna gain, low-noise pre-
amplifiers for 432 MHz, high quality coax, and accurate aiming are
necessary for success.
Pat, and others, have posted links to antenna construction sites which
are within construction capabilities of many amateur radio operators.

Field Day is coming again! Each year the American Radio Relay =
League (ARRL) sponsors Field Day as an emergency preparedness =
exercise. The event takes place during a 24-hour period on the =
fourth weekend of June. The Radio Amateur Satellite Corporation =
(AMSAT) promotes its own version of Field Day for operation via =
the amateur satellites, held concurrently with the ARRL event.
If you are considering ONLY the FM voice satellites like AMSAT-
OSCAR 16, AMRAD-OSCAR-27, SaudiSat-Oscar-50, or AMSAT-OSCAR-51 =
for your AMSAT Field Day focus. Don't, unless you are simply =
hoping to make one contact for the ARRL rules bonus points. The =
congestion on FM LEO satellites was so intense in prior years =
that we must continue to limit their use to one-QSO-per-FM-sat-
ellite. This includes the International Space Station. You will =
be allowed one QSO if the ISS is operating Voice. You will also =
be allowed one digital QSO with the ISS or any other digital, =
non-store-and-forward, packet satellite (if operational).
The format for the message exchange on the ISS or other digital =
packet satellite is an unproto packet to the other station (3-way =
exchange required) with all the same information as normally =
exchanged for ARRL Field Day, =
e.g.:
W6NWG de KK5DO 2A STX
KK5DO de W6NWG QSL 5A SDG
W6NWG de KK5DO QSL
If you have worked the satellites on Field Day in recent years, you =
may have noticed a lot of good contacts can be made on some of the =
less-populated, low-earth-orbit satellites like Fuji-OSCAR 29 (may =
or may not be operational), AMSAT-OSCAR 7. During Field Day the tran-
sponders come alive like 20 meters on a weekend. The good news is =
that the transponders on these satellites will support multiple =
simultaneous contacts. The bad news is that you can't use FM, just =
low duty-cycle modes like SSB and CW. =
2010 AMSAT Field Day Rules are in the process of being posted on the
