Hallo zusammen,
am nächsten Wochenende findet ein EME-Test mit dem weltweit größten Radio-Teleskop mit Hilfe der Amsat statt.

SB SAT @ AMSAT $ANS-101.06
Arecibo on 432 MHz Moon Bounce

AMSAT News Service Bulletin 101.06
From AMSAT HQ SILVER SPRING, MD.

To All RADIO AMATEURS
BID: $ANS-101.06

The Arecibo Observatory Amateur Radio Club will be putting the
1000-foot radio telescope on the air for 432 MHz EME from April 16-18.

It can be heard with a small hand-held yagi pointed at the moon

The scheduled times of operation are:

April 16: 1645 - 1930 UTC

April 17: 1740 - 2020 UTC

April 18: 1840 - 2125 UTC

Callsign: KP4AO

Tx Frequency: 432.045 MHz

Rx Frequency: 432.050 to 432.060+

Tx power: 400 W

Antenna gain: 60 dBi

System noise temp: 120 K (cold sky)

System noise temp: 330 K (when pointed at moon)

KP4AO can be heard with a small hand-held yagi pointed at the moon and a
good receiver. A 15 dBi antenna and 100 W will be enough to work us on
CW.

Operators at KP4AO will do their best to work as many stations as
possible. Each session will start with a brief announcement and CQ in
SSB. SSB QSOs may continue for 30 minutes to an hour, if the QSO rate
remains high.

The mode will be shifted to CW as soon as it is judged that higher QSO
rates would result.

We will listen for calls at frequencies 5-15 kHz higher than our own,
and even higher if QRM warrants. Callers who s-p-r-e-a-d o-u-t are more
likely to be copied.

If you've already worked us in any mode, please do not call again --
give others a chance.

If we call "CQ QRP", we will listen for stations running 100 W or less
to a single yagi. Please do not answer such a CQ if you are running more
power or have a larger antenna.

On April 18, if we reach a condition where most calling stations have
been worked, and we judge that operating in the digital mode JT65B would
produce a higher QSO rate, we will switch to JT65B.

Note that any of these planned operating strategies may be changed as
circumstances dictate.

We are extremely fortunate to have been granted access to the world's
largest radio telescope for this amateur radio good-will event. We look
forward to working as many stations as possible in the alloted time!

1. Astronaut Soichi Noguchi Chats with Texas Students via ARISS Contact

On Monday, March 29, Walnut Creek Elementary School students in Azle,
Texas took
part in an Amateur Radio on the International Space Station (ARISS)
contact with
JAXA astronaut Soichi Noguchi, KD5TVP. All 23 questions were answered with time
for a two way "Goodbye." ARISS was integrated into the science curriculum as
students researched space objects and gave presentations to their class. The
youth also attended satellite communications demonstrations given by retired
Lockheed employees and members of local radio clubs. On the day of
the contact,
a proclamation was read by an Azle City representative declaring it to be Space
Day in Azle. Four television stations and one local newspaper
covered the event
and the audio was available on EchoLink.


2. HAMEX 2010 ARISS Exhibit

HAMEX 2010, the largest RadioFest in Canada, was held on Saturday, March 27 in
Toronto. AMSAT (Radio Amateur Satellite Corporation) and ARISS
(Amateur Radio on
the International Space Station) members attended the event and manned an
exhibition booth which displayed two mini satellite communications stations as
well as information boards with pictures of astronauts involved in the ARISS
program. A large AMSAT banner was posted, along with two 7 foot posters on loan
from the Canada Space Agency (CSA). CSA also provided handouts, stickers and
various magnetic logos, which along with pamphlets describing AMSAT and the
ARISS program, were distributed to the many visitors the exhibit attracted. The
event was a success in generating interest in the ARISS program and
the team was
invited back next year.

Ich wünsche allen OMs viel Erfolg, dieses tolle Signal auf 70cm vom Mond hören zu können.
Ich werde morgen noch mal die Mondlaufbahn prüfen.

Hallo Attila,
das könnte am Freitag passen. Der Mond wird um etwa 19:30 UTC laut Orbitron im Westen untergehen. Heute ist der Mond in etwa Sonnenhöhe und Freitag ist der Mond weiter zurück gefallen.
