Date: Fri, 8 Feb 2008 12:25:42 +0100 Hello Drew, Frei Island is located out of the footprint of the ISS, Pacsat, and AO-27 is invariably switched off by the time it gets up here ... therefore, the APRS mode has never been a viable propasition for me. I was just reading Bob's WB4APR many web pages re: APRS and he refers to ECHO (now AO-51) frequently ... mentioning the APRS system. I can't recall seeing AO-51 in the V/U (J) mode for APRS operations. Bob gives the "impression" that this mode can always be operated regardless of which other mode the satellite is in. Is this true? ... and can AO-51 *ALWAYS* be used as an APRS sat ???. 73 John. <la2qaa(a)amsat.org>

Satellites and D710 auto tune

Yes, these alerts help all mobiles in an entire city to see when a bird is in view with not only the direction and distance to the bird but more importantly the frequencies and doppler. Just tune and operate. See the details at the bottom of this page: http://www.ew.usna.edu/~bruninga/localinfo.html In fact, you can even configure your D700 with Voice module to speak these alerts when the satellites come into view. It sure beats lugging around a tracking computer on your long commute. Bob, WB4APR

Thanks so much for all of the replies. I wasn't up to date on the schedule for AO-51. I made my first contact from Hawaii this evening (Thursday) and I'm quite thrilled. I'll try again Friday evening during at least one of the two passes visible from Hawaii. jeff AD6EO Armour, Randy (ITS) wrote: > Jeff, > > I'm not in Hawaii, but think I know why you may not have heard anyone. > Tuesday, Wednesday and today (Thursday) the uplink frequency is > 1268.700M MHz.

by Bauer, Frank H. (GSFC-590.0) 07 Feb '08

Joe, The D700 is owned and controlled by ARISS--Amateur Radio on the International Space Station. ARISS is an international working group of volunteers with delegates from AMSAT-International and the National Amateur Radio organizations. In the USA this is AMSAT-NA and the ARRL. The ARISS team works with the 5 regonal space agencies (NASA, CSA, JAXA, ESA, and Roscosmos/Energia) to develop and operate the amateur radio equipment on board ISS. In 1996, NASA asked the amateur radio community to develop a working group to provide a single amateur radio voice to the space agencies...the result was ARISS. The ISS crew use the ham radio equipment at their discretion on their free time. Like you and me, they have many choices on how to spend their free time, including reading books, watching movies, talking to their families and using the ham radio. Some crew members only use ARISS on their free time to talk to children at schools. Others are more into ham radio...they support the school contacts and will talk to hams on the ground. There are several future crew members in the fall time frame that have expressed significant interest in using the ARISS equipment for general QSOs. We will keep you informed as their flight nears. Thank you very much for your interest in ARISS. 73, Frank Bauer, KA3HDO ARISS International Chairman AMSAT-NA V.P for Human Spaceflight Programs From: amsat-bb-bounces(a)amsat.org on behalf of joe cassano aka jmario Sent: Thu 2/7/2008 5:51 PM To: amsat-bb(a)amsat.org Subject: [amsat-bb] Re ISS D700 msg in AMSAT-BB Digest, Vol 3, Issue 71 I'm curious to learn what organization owns/controls the D700 that is on the ISS and how, where, when, and by who decisions are made and implemented regarding switching the D700's mode of operation. I understand the D700 shutdowns for safety reasons, its use as a educational tool to connect school children worldwide with NASA, its availability as a recreational device for interested ISS residents, and the fact that having astronauts watching over and tweaking the D700 is near or at the bottom of the astronaut's task list. I have never understood how the non-shutdown, non-school D700 time is allocated and who does the allocation.

Congratulations!!
by Frank H. Bauer 07 Feb '08

07 Feb '08

All, I would like to extend my congratulations to the ARISS-Europe team on today's successful launch of our newest on-orbit hardware delivery---additional ARISS antennas!! The antennas are mounted on the European Columbus module which flew inside the payload bay of the Space Shuttle Atlantis. The ARISS-Europe team have been working hard and diligently for over 5 years to realize this outstanding milestone. The team faced numerous challenges, including some very severe environmental testing to get approval to fly these antenna systems. I would like to thank Gaston Bertels, ON4WF for his outstanding leadership on this project and Dr. Pawel Kabacik at the Wroclaw University of Technology in Poland for his efforts in the antenna design and testing. And I would like to extend my sincere gratitude to all those who contributed to this project through their volunteer efforts, financial contributions and/or in-kind contributions. YOU helped us develop, test and fly these antennas. For more information on the ARISS antennas, see: http://www.ariss-eu.org/ 73, Frank Bauer, KA3HDO ARISS International Chairman AMSAT-NA V.P. for Human Spaceflight Programs

It was version 0.6.1-1ubuntu1, from Ubuntu's hamradio package repository. I removed it and installed 0.8.0-2 from debian.org, and it seems to work fine. Thanks.

gpredict help
by George Henry 07 Feb '08

07 Feb '08

I've just started playing around with Ubuntu linux, and installed gpredict 0.6.1-1ubuntu1 using the Add/Remove progams package installer, as a user with system administration rights. According to Synaptic Package Manager, all of the dependencies are met and the installation is not broken. I can run gpredict, but there is no Update TLE option visible from the file menu. What did I do wrong? Is this one of those crazy permissions issues I've heard about? George, KA3HSW
