This week's ARISS Status Report says the "Associazione Italiana Radio-
ascolto" A.I.R. (Italian Radio Listeners Association) has awarded the 
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."  
The prize will be delivered on May 8 in Faenza during the A.I.R. annual 
meeting.

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:

BID: $ANS-073.03

The 3W6C-Team will activate Côn Có Island (AS-185) near Viet Nam 
on satellites from April 10-18, 2010. The crew use a FT-897 trans-
ceiver with homebrewed "Easysat" antenna for 2m and 70cm and a 
homebrewed 10m cross dipole for AO-7 Mode A.
 
The team plans to use AO-07*, AO-51*, HO-68*, SO-50, and SO-67.
(*first priority on passes when the satellite team is available.)
AO-07 will be activated in SBB/CW-mode and ll other satellites 
will be in FM-mode.
 
The main areas in the footprint are: East-Asia, Japan, China, India, 
Australia and east part of Russia. If possible, the 3W6C-Team will 
use some DX-Windows to near East and west part of Russia.
 
The main-operator for Satellite will be Hans-Peter, HB9BXE. The
satellite station will be operating in manual mode without auto-
matic doppler correction or tracking. On AO-7 expect him to search
the his downlink frequency +/- 5KHz to establish contacts. If there
is a pileup on the satellites please transmit only your callsign, 
signal strength and gridsquare.

All DXpedition crew members are primary shortwave operators. So 
please be patient if they have some difficulty with satellite
operation.
 
For additional information and operating-plan, please see the 3W6C

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 – 435.060 MHz
Downlink 145.960 – 145.980 MHz
Beacon   145.955 MHz CW and BPSK 

AMSAT-UK publishes a colour A4 newsletter, OSCAR News, that is full 
of Amateur Satellite information. Information to join AMSAT-UK can be

RSGB Response to OFCOM WRC-12 Consultation Includes Satellite Bands

AMSAT News Service Bulletin 073.05

March 14, 2010
To All RADIO AMATEURS
BID: $ANS-073.05

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.

In preparation for the World Radiocommunication Conference 2012 
(WRC-12) the Radio Society of Great Britain (RSGB) has provided
the the UK communications regulator OFCOM with a response cover-
ing concerns and planning for future satellite frequency alloca-
tion between 50 MHz to the microwave bands.

The RSGB response expressed concern about the use of high powered 
VHF Radar at 142-144MHz immediately adjacent to the weak signal 
section of the Amateur Primary 144-146MHz allocation. It says that 
the 53830-5850MHz Amateur Satellite Service downlink allocation 
should be protected from harmful out of band emissions from High 
Altitude Platform Stations (HAPS). 

Amateur Satellite Service allocations at 50MHz and 3400MHz are 
identified as medium term objectives in the response of Radio 
Society of Great Britain (RSGB) to the WRC-12 consultation held 
by the UK communications regulator OFCOM:

These medium/long term objectives were identified: 
+ Amateur allocation at 5 MHz with expanded allocations at 7, 10, 
  14, 18MHz. 

+ A 50MHz Amateur Satellite Service allocation.

+ Allocation of 3400-3410MHz to the Amateur Satellite Service in 
  ITU Region 1. 

+ Allocations 10-50MHz wide at low atmospheric attenuation spots 
  between amateur 10, 24 and 47GHz allocations. 

+ Amateur and Amateur Satellite Services experimental access or 
  formal allocations above 275GHz.

John, K8YSE posted a map this week showing the map of the at least 
86 different grids worked by Jim, ND9M during his recent 6 week road
trip. John says the red grids are ones that he worked ND9M in and 
blue grids are the ones he missed. See: http://www.papays.com/nd9m.jpg

John wrote, "I've received several inquiries about the software
that was used to create the ND9M/p road trip grid square plot.
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.

Update on Arecibo EME Activation

AMSAT News Service Bulletin 073.08
>From AMSAT HQ SILVER SPRING, MD.
March 14, 2010
To All RADIO AMATEURS
BID: $ANS-073.08

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.

First Reminder for 2010 AMSAT Field Day Competition

AMSAT News Service Bulletin 073.09
>From AMSAT HQ SILVER SPRING, MD.
March 14, 2010

BID: $ANS-073.09

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
amsat web pages in the near future. Watch for an announcement when the
document (.doc and .pdf) is available.
