Howard Long G6LVB

The AMSAT/TAPR Banquet on Friday night, May 18 is one of the main AMSAT activities during the 2012 Hamvention at Dayton.

AMSAT-NA is pleased to announce that Howard Long G6LVB will be the featured speaker for the evening event. Howard will be talking about his  FUNcube Dongle, the 64 – 1700 MHz Software Defined Receiver.

This innovative USB device is the size of a thumbdrive and has an SMA antenna socket. Multiple SDR control and display software programs can be used with the FUNcube Dongle.

Banquet tickets will not be sold at the AMSAT booth during the Hamvention so reservations must be made through the AMSAT-NA Store http://www.amsat-na.com/store/item.php?id=100158
Tickets are $30 apiece.

Thanks to Gould Smith, WA4SXM for the above information

AMSAT-UK Net Recorded via 20 km WiFi Link (March 11th)

AMSAT-UK Net Recorded via 20 km WiFi Link

Simon Brown HB9DRV in Switzerland has made available a recording of Sunday’s AMSAT-UK 80m net that he made using a remote receiver in Poole, Dorset. What is remarkable about this recording is that a 20 km long experimental 2.4 GHz WiFi link was used at the Dorset end.

The AMSAT-UK net is held every Sunday morning at 10am local time on a nominal frequency of 3.780 MHz. Due to interference the net may move either side of that frequency so tune around. Newcomers are most welcome to call-in.

Listen to the AMSAT-UK Net recorded Sunday, March 11th, 2012. Due to the experimental nature of the 20 km WiFi link there are a few breaks in the recording.

Radio Amateur Encourages Engineering as a Career

Ali Guarneros Luna KJ6TVO has been involved in the development of the amateur radio CubeSat TechEdSat. In this video she talks to teenagers at a Careers Night about her aspiration to become an engineer.

Watch Career Night – Ali Luna

Ali Guarneros Luna KJ6TVO was born in Mexico City and now lives in San Jose, California. She received her BS in Aerospace Engineering at San Jose State University in 2010 and will complete her MS in Aerospace Engineering from San Jose State University in 2012.

She currently works with the Edison Program, Small Spacecraft Payload and Technologies (SSPT) and SPHERES National Lab at NASA Ames Research Center. Under the Edison Program, Ali works on development of CubeSat projects, including TechEdSat, as the System Engineering, Mission And Ground Operations, and Launch Vehicle Service expert.

Under the Small Spacecraft Payload and Technologies Program, Ali works as Engineering Support for different missions, most currently in NLAS. At SPHERES National Lab, Ali works as Engineer support for Ground Lab and Operation Support.

RAX-2 Success – Anomaly Detected

RAX-2 Detects Comms-Disrupting Anomaly

RAX-2 Detects Communication-Disrupting Anomaly http://rax.sri.com/

Matt Bennett KF6RTB reports that the amateur radio CubeSat, Radio Auroral Explorer 2 (RAX-2), has detected the communication-disrupting anomaly in the upper atmosphere it was searching for. The team have expressed their thanks to the amateur radio community.

RAX-2 was built by students at the University of Michigan. The primary objective of the mission is to use the onboard radar receiver in conjunction with a powerful radar station in Alaska to study the formation of a plasma anomaly known for causing the scintillation of radio signals in the UHF and higher bands. This scintillation effect is known to inhibit our space radar tracking capabilities and ground-space communications. Studying this anomaly in this bi-static radar configuration (ground based transmitter, space-base receiver) will provide scientists with a better understanding of these anomalies that has not been achievable with ground radars alone.

Late on Friday, March 9, Matt KF6RTB announced the news:

This is unbelievable!! After more than three years of hard work and dedication by my team and professor at Michigan, our chief scientist confirmed today that the RAX-2 spacecraft we designed, built, and launched into space has detected the communication-disrupting anomaly in the upper atmosphere that we’ve been looking for!! Cheers guys, we did it!!! GO guys, we did it!!! GO BLUE!!!! [Michigan Athletics battle cry]

The RAX Team would like to acknowledge and say thank you to the amateur radio satellite community for all of their support on this mission. We’ve really enjoyed interacting with fellow operators while collecting and analyzing telemetry. We’ve also learned a great deal about satellite operations from each other.

ISS Symposium 2012 “Research in space for the benefit of humankind”

Radio amateur Andy Thomas G0SFJ has been invited to the ESA ISS Symposium 2012 to be held in Berlin, May 2-4.

The Symposium aims to review and discuss the key accomplishments in research made to date, looking at case-studies in fundamental and applied research and the actual or potential spin-offs for the benefit of humankind, as well as to discuss the future path and priorities for research on ISS.

The Symposium will take place at the Hilton Hotel in Berlin, Germany, starting at 13h00 (after lunch) on Wednesday, May 2, and will run until around 13h00 on Friday, May 4, 2012. Attendance will be free of charge for all invited and registered guests.

New Horizons Stamp Drive

As fast as NASA’s New Horizons spacecraft is heading toward Pluto, the drive to honor this historic exploration of the ninth planet is speeding toward its finish. Less than a week remains to put your name on the petition supporting an effort for the U.S. Postal Service to commemorate Pluto and New Horizons on a postage stamp.

In just over a month since the drive was announced, more than 10,000 people have signed the online petition. But mission leads would like to have many more signatures before they close out the list on March 13 – the 82nd anniversary of the announcement of Pluto’s discovery by American astronomer Clyde Tombaugh.
