This weekend's Plasma Thrust space experiment using Amateur Radio has been postponed until after the delivery of a new rig next April.

This year’s Jamboree On The Air takes place on 15 and 16 October.
NA1SS, which is the International Space Station ham radio callsign, is going to be on the air throughout the JOTA weekend. Astronaut Mike Fossum, KF5AQG, who is also a Scoutmaster, is going to be on the air during breaks from his work schedule. He should be available on most of the passes around the world. The uplink is 145.200MHz and the downlink is 145.800MHz, both plus and minus Doppler shift as the ISS passes overhead. Within this year's JOTA,(jamboree on the air).

NASA is seeking U.S. formal and informal education institutions and organizations, individually or working together, to host an Amateur Radio on the International Space Station, or ARISS, contact between the dates of January 15 and July 15, 2012.

This pass Saturday Mike Fincke - KE5AIT was active on the International Space Station during the day.

At 1609 UTC he was active via NA1SS over the Caribbean, and had a QSO with Angel, WP3GW, while he was calling CQ.

There is a video posted on YouTube of the QSO:

The planned operation of ARISSat-1/RadioSkaf-V/KEDR on April 11 and April 12 from inside the International Space Station as part of the commemoration of the 50th anniversary of Yuri Gagarin's flight was not successful. No earth stations on the ground reported hearing transmissions on the ARISSat-1 downlink(145.950 MHz for FM analog/145.920 MHz for digital). The planned retransmission of the satellite's FM downlink via the Kenwood TM-D700 transceiver --currently used for ARISS contacts--was also not successful as no reports were received of signals heard on 437.550 MHz.

SILVER SPRING, MARYLAND (AMSAT News Service) While awaiting deployment from the International Space Station (ISS) in late July, an amateur radio satellite specifically designed to interest students in scientific and technological careers will be activated and begin transmissions from the ISS in mid-April of this year.

There is update about the IR3UEF repeater operated by the Italian Amateur Radio Association (ARI, Chioggia Section) and interfering with the main ISS Downloank (145.800 MHz).

Tomorrow a scheduled ARISS contact will take place in Italy and Italian Astronaut Paolo Nespoli will respond to questions asked by the students. It's a joyful event for Italy and anybody who is interested will be able to participate by simply tuning a portable radio on 145.800 MHz.

Anybody except students who reside in the Venice area.

Why? The explanation is simple, but hard to believe: the Italian Amateur Radio Association (or ARI, Chioggia section) decided to install  the IR3UEF repeater right on 145.800 MHz, the worldwide ISS downlink.

Apparently, Italy is not the only country invading the ISS frequencies, but still a good example to start investigating this issue.

UPDATE
11 January 2001: The 145.800 MHz port of IR3UEF has been shut down. Read more
