Hi Michael, OH2AUE
I am very happy to see that AMSAT-OH is working on the S/X band
coherent/linear transponder for P3E/P5A
Don't forget what you promises on 11 may 2008 about the frequency
band for the Downlink Linear 10451.000 MHz ~2 MHz because
many of us are already equipped with X band downconverters and dishes
covering from 10450.000 to 10452.000 MHz originally made for AO40
never tested on it and now becaming rusty on the roof as you can see at
i8CVS in QRZ.com
>From your block diagrams written in finnish I see that 10.450 GHz is still
there and I am very happy with it.

I noticed that UO-22 might be passed over just 100000 of the orbit
number before long. UO-22 was launched on 17 July 1991.
It's now Non-Operational.
UO-22
1 21575U 91050B 10148.66466669 -.00000020 00000-0 77105-5 0 8445

The above kep is 'NORAD TLE Sets Current Data'.
The orbit number is 99041, so 959 to 100000.
100000 - 99041 = 959 ... orbit numbers until 100000
959/14.39719412 = 66.61020140 ... orbits/mean motion = days
148.66466669 + 66.61020140 = 215.27486809 ... epock time
The epock time 215.27486809 is 06:35:48 UTC, 3rd Aug 2010.
It maybe contains +/- one and a half hour's obserbational lag.
In addition, the counter number returns to 0 when the orbit number
exceeds 100000.

The Brazos Valley Amateur Radio Club (BVARC) will be participating in
the Museum Ships Weekend event on June 5-6, 2010 from Pelican Island
(IOTA NA-143) near Galveston, Texas. BVARC plans a full 2-day operation
and will very likely be the only group in Museum Ships Weekend working
OSCAR satellites.
It is expected that amateur radio operators will activate amateur radio
stations on over 70 ships worldwide during the event. The BVARC opera-
tion from Seawolf Park will activate both the submarine USS Cavalla and
the destroyer escort USS Stewart.
The planned operation on OSCAR satellites will take place on Saturday,
June 5, 2010 on the 1550 UTC and 1731 UTC passes of SO-50, and on the
1931 UTC pass of AO-27. The call sign will be the BVARC club station

BID: $ANS-150.06
On June 3rd, 2010, the Launch of Mars500 mission will begin in Moscow.
The first full-duration simulation of a human mission to Mars is about
to begin.
After closing the hatch, the crew of six will remain in their ?spacecraft?
for 520 days.
The 520-day simulated mission to Mars will start on 3 June, when the
isolation facility is sealed and the international crew start their
record-breaking experiment.
The crew will basically live and work like astronauts on the International
Space Station, with maintenance work, scientific experiments and daily
exercise. They will follow a seven-day week, with two days off, except
when special and emergency situations are simulated.
Ed. Note: Now here is an example of plenty of free time for the Astronauts.
A 2.4ghz Txmitter and a 1.2ghz RXcvr would go great to occupy their time.
Maybe
Even a spacewalk to put up 2 umbrella type antennas to communicate back to
Earth.
(They could use some short whips or small beams on 2 and 435 for the Earth
Bound
simulation even talking through AO-51)
There are six crewmembers plus a Russian backup: ESA-selected Diego Urbina
(Italian/Colombian, age 27) and Romain Charles (French, 31);
Sukhrob Kamolov (32), Alexey Sitev (38), Alexandr Smoleevskiy (33)
and Mikhail Sinelnikov (37) from Russia; and Wang Yue (26) from China.
Housed in Russia?s Institute of Biomedical Problems (IBMP) in Moscow,
the 550 m? sealed space mockup includes an interplanetary spaceship,
a Mars lander and a martian landscape.

1. School Contacts
The Wireless Institute of Australia (WIA) in Bayswater, Victoria, Australia
was scheduled for an Amateur Radio contact with the International Space
Station (ARISS) on Saturday, May 29 at 10:43 UTC via ON4ISS in Belgium.
The WIA will held a special dinner to celebrate its centenary and has
invited
students from local schools in Canberra to make an ARISS school contact
on that evening. It is anticipated that this dinner will be a high key
event with Australia wide coverage.
Istituto Comprensivo Camaiore - Scuola Secondaria 1? Grado ?M. Rosi,?
Camaiore, Italy has been scheduled for an Amateur Radio on the
International Space Station (ARISS) contact on Saturday, June 5 at 10:21
UTC.
Students participating in the contact have learned about space science,
principles of radio communications and the benefits of space
exploration and have prepared to use English in a real life situation.
2. ARISS Contact for Pita Kallak School
An Amateur Radio on the International Space Station (ARISS) contact was held
between Pita Kallak School in Kuujjuaq, Quebec, Canada and on-orbit
astronaut
Timothy Creamer, KC5WKI on Thursday, May 20. Telebridge station ON4ISS in
Belgium provided the connection. Some technical difficulties were
encountered,
but nine questions were answered during the session. In preparation for
the contact, students learned about the ISS and amateur radio through video,
the internet and guest speakers and created science related projects in the
classroom.
3. ARISSat Presentation Available for Viewing
Gould Smith, WA4SXM gave a presentation on ARISSat-1 at the Dayton
Hamvention,
held over the May 14-16 weekend. His presentation has been posted to
YouTube. See: http://www.youtube.com/watch?v=VEDfSCw6VcU
4. ARRL QST Covers ARISS
The American Radio Relay League (ARRL) June QST carried an article by Steve
Ford,
WB8IMY titled, "Ground Control to Major Tom." The story was about ARISS
and making general contacts with the ISS crew members. It started off with
how ARISS is mainly to enhance youth STEM (Science, Technology, Engineering
and Math) education, but that all amateur radio operators can have an ARISS
contact. It talked about the types of contacts and included a picture of
astronaut Mike Fincke. Then it talked about Richard Garriott and his SSTV
(Slow Scan Television). The ARRL monthly journal has a circulation of
150,000.
5. Astronaut Training Status
Astronaut Don Pettit, KD5MDT had a productive ham radio training session
review on May 19. He expects to be active with the amateur radio system
while on the ISS and is currently assigned to Expedition 30.
6. ARISS Presented at Scout-O-Rama
?Scout-O-Rama? was held over the May 15 weekend in Wheaton, Illinois.
ARISS Mentor John Spasojevich set up an exhibit about amateur radio and
ARISS at this event.

Hi in Italy,
I just listened to a pass of AO-27 with AOS at
1406 UTC here in Copenhagen.
There were 2-3 Italian stations on in terestial
communications.
They were radio amateurs using calls - but too fast for
me to make out. IW9??? and IZ????.
I am not sure but may be it is a repeater. There were a distinct
67 Hz tone on.
I could make out two city names: Catania and Modena.
If some satellite users know what it is please try to make
them stop.
Have a nice Sunday.

With the latest firmware installed from Alinco's Web site, I have been told
that the DJ-G7 is a good TRUE duplex performer - where you CAN monitor the
sub-band while transmitting on the other.

It still desenses. What else is there to elaborate on? I think firmware
changing the filter characteristics of a non-SDR radio is, ummm,
optimistic. If someone is looking for a new full-duplex HT, they should
be prepared to jump on the new Kenwood as soon as it's released. Your
mileage may vary.
