Following the selection of 9 cubesats to be launched on the maiden flight =
of
the Vega launcher, ESA have now announced that the cubesats will be deployed
into a very interesting orbit measuring 350km x 1450km with an inclination =
of
71 degrees.
>From the ESA website
"The nine CubeSats will be deployed from three different deployment systems
mounted on the support structure of the main payload, LARES (LAser RElativi=
ty
Satellite), into an orbit of 350 km by 1450 km at an inclination of 71
degrees. The launch opportunity is offered by ESA to the selected CubeSats
free of charge"

VHF/UHF/microwave pioneer Reg Galle, VK5QR, SK

AMSAT News Service Bulletin 321.04
From AMSAT HQ SILVER SPRING, MD.
November 16, 2008

All those interested in long distance VHF/UHF/microwave propagation will
regret the death of Reg Galle VK5QR on 12 September 2008.
Reg was a leading pioneer of the use of these amateur radio bands.
On 31 December 1951, Reg made a 144 MHz Australian record distance of 2122 =
Km
with a contact with the late Rolo Everingham VK6BO in Perth (just short of =
the
then world record of 2253 Km). He then continued to seek
answers to questions regarding the propagation of the higher bands.
Reg became the Adelaide end of record breaking distances on 432, 1296,
2304 and 3456 MHz across the Great Australian Bight with Wally Green
VK6WG in Albany.
Reg and Wally, as true amateurs with no professional engineering
backgrounds, built equipment for these UHF/microwave bands and were
nearly 2 000 Km apart so that there were no "local" tests with each
other. There were no precedents in Australia, and few in the world, for
trying to make contacts over this distance.
In 1977, they bridged the 1296 MHz path on 25 January for a world record
distance of 1885 Km.
The following year, on 17 February 1978, Reg and Wally made their first
contact on the 2304 MHz band. Reg used SSB that was processed in a
divide by 6 circuit and mixed to 28 MHz. The 28 MHz signal, with
processed SSB, was then transverted to 384 MHz and then tripled and
doubled to 2304 MHz. This multiplication by 6 restored the original
SSB! To give you a feel of the type of gear in use 30 years ago, Wally
Green VK6WG used a modified World War II SCR522 which, from a 7 MHz
crystal, produced 128 MHz. This was then multiplied to 384 MHz with a
BAY96 varactor tripler to 1152 MHz in a modified Microwave Modules
MMV1296 and then doubled in by a 2C39 which drew 90mA at 600V.
In 1986, Reg and Wally completed their first 3456 MHz contact using CW.
This distance of 1885 Km and that on 2304 MHz remain the Australian
record distances.
Both Wally and Reg built equipment for the 5.7 GHz band and made tests
on that band without success although Reg claimed that they could have
had a contact had Wally not been in the midst of making apricot jam on
that day!
Reg gradually lost interest in pushing the boundaries further and has
been in poor health in recent years. His death followed several
strokes. The most recent one returned him to hospital just over a week
ago but he insisted that he wanted to go home despite living alone and
with no close relatives in Adelaide. His niece watched over him and he
was able to fulfil his wish of dying at home in his own bed! Reg was 96
years old!
Farewell to a tremendous pioneer on the higher bands!

1. Spanish Students Speak to ISS via Radio
Students attending IES Trassierra in C=F3rdoba, Spain spoke with astronaut =
Mike
Fincke, KE5AIT, via an Amateur Radio on the International Space Station (AR=
ISS)
contact on Monday, November 3. Twenty students asked one question each of =
the
astronaut. Approximately 150 students, teachers and guests attended the eve=
nt
including the Cordoba City mayor and the Head =
Master of Education and Culture of
Cordoba. Media coverage included 4 local and regional television stations, 2
local and regional radio stations and 3 newspapers. Photos, an audio recor=
ding
and a video recording may be found at: http://www.ariss-eu.org/2008_11_08.=

2. Successful Australian Contact
In preparation for an Amateur Radio on the International Space Station (ARI=
SS)
contact, students attending St. Thomas=92 Primary School in Brisbane, Queen=
sland,
Australia helped build an antenna. They spoke with Richard Garriott, W5KWQ,
during his ISS mission and received Slow Scan Television (SSTV) images as w=
ell.
They also viewed Mike Fincke=92s ISS video tour taken during Expedition 9. =
On
Tuesday, November 4, the students spoke with Fincke, KE5AIT, as approximate=
ly
400 students looked on. Fincke answered all =
twenty questions posed to him by the
20 students. The event received extensive local and national media coverage
including 2 newspapers, an online magazine, 2 television stations and 5 rad=
io
stations. The audio and a partial video of the event are available on the

An Amateur Radio on the International Space Station (ARISS) contact between
Dibrugarh University in Assam, India and astronaut Mike Fincke, KE5AIT, took
place on Friday, November 7 via telebridge station W6SRJ in California. Ten
students were able to ask eleven questions of Fincke as an audience of 700
gathered for the event. Mike spoke briefly in the Indian language. Media
coverage included newspapers and television. Contact audio was fed into two
EchoLink servers and into the Internet Radio Linking Project (IRLP) Discove=
ry
Reflector 9010. There were 5 known connections from England, Japan and South
Korea on the EchoLink servers with uncounted listeners on one repeater and =
two
link nodes.

KC5ZTH, took part in Amateur Radio on the International Space Station (ARIS=
S)
simulated contacts. The astronauts spoke with two groups of students from
Manordale Public School in Ottawa, Ontario, =
Canada. These training sessions were
terrestrial-based amateur radio contacts using ARISS-equivalent equipment.
Hadfield and Coleman are currently assigned as back-up Expedition 19 crew
members.
5. ARRL Articles on Garriott Mission
On Thursday, November 6, the American Radio Relay League (ARRL) ran an arti=
cle
on Richard Garriott=92s mission. =93Richard Garriott, W5KWQ, Back on Terra =
Firma,=94

6. Interview on SuitSat
ARISS (Amateur Radio on the International Space Station) member Steve Bible,
N7HPR, gave an interview on the concept and development of SuitSat-1. His
interview has been posted to the Design News, Engineering Concept Conduit W=
eb
page. See: http://www.engineeringconceptconduit.com/
7. Astronaut Makes General Contacts
Mike Fincke, KE5AIT, made several contacts with =
the ham radio community over the
November 8 weekend. Using the Amateur Radio on the International Space Stat=
ion
(ARISS) equipment, Fincke talked with stations in Australia, Thailand, South
America and North America.
8. ARISS SSTV Web Site Status
The Amateur Radio on the International Space Station (ARISS) Slow Scan
Television (SSTV) Web site set up for Richard Garriott=92s flight was a big
success. Over 2200 images from SpaceCam, MMSSTV and the VC-H1 were received=
by
amateur radio operators worldwide and were uploaded to the site. The site
received nearly 4 million hits! See the SSTV images:
