Australian Reciprocal Licensing Changes
by Trevor 09 Feb '08

09 Feb '08

The Australian Communications and Media Authority (ACMA) has announced changes to the Amateur licence. Among the changes they now permit the Encoding, for the purpose of Obscuring the meaning, of control signals for Amateur Satellites or unattended stations. >From WIA News: ---- This is Michael Owen VK3KI President of the Wireless Institute of Australia. Today I am able to tell you of 3 major decisions made last Thursday by the ACMA board. In short, the news is that ACMA has made the Determination to amend the Amateur LCD to make the last of changes foreshadowed in the Outcomes published in May 2004; ACMA has issued the Class Licence allowing visiting amateurs to operate in Australia without any other Australian licence, which is hopefully the last steps from our end before Australian amateurs can operate in the CEPT countries on the basis of their Australian Advanced licence, and finally ACMA has announced who has been successful in submitting its expression of interest in the amateur examination management, certificate and certain call sign functions outsourcing. Those are the headlines. Now, for a little detail. The amendments to the LCD are quite extensive. Let me try and summarise the major changes: The prohibition on the connection of automated systems to a public telecommunications network, which includes the Internet, has been removed. Foundation licensees cannot make such connections, but Advanced, Standard and Repeater licensees can, but now must "implement reasonable measures to ensure that only appropriately licensed person access the station." New, and not foreshadowed in the ACA Outcomes, is an obligation on Standard and Advanced licensees (but not repeater licensees) to warn a person connected to an amateur station from a public telecommunications network that they can be heard by others. Now, signals encoded for the purpose of obscuring the meaning may be used for controlling a satellite or an unattended amateur stations or in emergency operations. The AX call sign will be able to be used on Australia Day, Anzac Day and World Telecommunication day without doing more. A number of matters are made clear for the Foundation licensee. At last, 10 watts may be used for all permitted modes. But a Foundation licensee cannot allow a person who is not an amateur to use his or her transmitter, or operate his or her station in automatic mode or computer controlled mode or operate his or her station directly connected to a public telecommunications network. The obligation for all stations in a net to identify all stations every 10 minutes is relaxed for emergency networks, so that one station may identify all stations every 30 minutes. There is now a clear requirement that a person operating through a repeater must be licensed to operate on the repeaters output frequency. As foreshadowed in the Outcomes paper, the Amateur LCD now defines limits to spurious emissions, in fact the ITU limits already applying to the amateur service. A new and rather complex definition of "operate" defines how an amateur station may be used by someone who is not an amateur. The Amending Determination comes into effect the day after it is registered, probably next Monday or Tuesday. I hope that a copy will then be available on the WIA website. I have also written a paper that describes in more particular terms the changes, and that is already available on the WIA website. In probably 3 or 4 weeks a consolidated version of the Amateur LCD incorporating these amendments will be published. That will be a lot easier to read, and something everyone will need to have. The next major piece of news is that the ACMA has issued a class licence to allow visiting amateurs to operate in Australia for up to 90 days using their home call sign followed by the suffix VK followed by "portable" and then the location of the station, without doing anything more. That class licence comes into effect on 14 February. There are 5 levels of visitor licence, 3 matching the Australian Advanced, Standard and Foundation licenses, a VHF licence, and finally, in effect, a 146 to 148 FM licence. The privileges of each level are set out in the class licence. ACMA will publish on its website a table showing equivalencies to the Australian visitor levels for different overseas licences. This class licence for visiting amateurs is, we hope, the final step before CEPT allows Australian Advanced licensees to operate a in the CEPT countries, some 32 countries mainly in Europe, using their Australian call sign, without doing more. The WIA will let everyone know immediately CEPT has allowed Australian amateurs to operate under what is called TR 61 01. I hope that a copy of the Class Licence will also be available on the WIA website next Monday or Tuesday. All of these changes mean that extensive changes are currently being made to the ACMA website, but they won't all be in place immediately. Please be patient. Now the final piece of news. As you know, the WIA has repeatedly expressed its concern that its role as the manager of the amateur examination system has not been secure. Finally, last year the ACMA advertised for expressions of interest to provide the examination management function, to issue certificates, and certain call sign functions. The WIA has been advised that its expression of interest met all the criteria published by ACMA for the tasks, and that ACMA will now negotiate the terms of a contract with the WIA to cover these matters being outsourced. Together, these three matters are of great importance to Australian amateurs, with now only one matter outstanding, that is for CEPT to accept that VK licensees can operate in the CEPT countries as we will allow their licensees to operate after 14 February. ---- Australian Communications and Media Authority (ACMA) http://www.acma.gov.au/WEB/HOMEPAGE/PC=HOME ACMA Amends Amateur LCD http://www.wia.org.au/newsevents/news/2008/20080208-3/index.php The New Australian Amateur Radio Regulations http://www.wia.org.au/newsevents/news/2008/20080208-3/documents/The%20New%2… 73 Trevor M5AKA --------------- Daily Amateur Radio RSS News: http://www.southgatearc.org/ Email your news items to: editor at southgatearc.org News On Your Website: http://www.southgatearc.org/rss/index.htm News On Your PC: http://www.southgatearc.org/rss/newsreader.htm Upload Your News: http://www.southgatearc.org/news/your_news.htm --------------- __________________________________________________________ Sent from Yahoo!

Re ISS D700 msg in AMSAT-BB Digest, Vol 3, Issue 71
by joe cassano aka jmario 08 Feb '08

08 Feb '08

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.

oscar 16 and hamsat
by Thomas McGrane 08 Feb '08

08 Feb '08

greetings to the group Many thanks to everyone for configuring oscar 16 for phone operation. Pretty good SSB reception with the preamp. On another note, I invite everyone to try HAMSAT or VO-52. It has a spectacular 2 meter SSB signal that can be received on an all-mode rig without a preamp. All you folks that want a linear transponder should be using this bird to keep in practice for future HEO's. Over the past 3 years since the launch of ECHO, I have purchased used UHF and VHF all-mode rigs and built antennas. Basically I'm "Gearing" up for P3E and Eagle. 73, pat

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>

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

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.

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

AO51 Easy Passtimes and SSET
by Robert Bruninga 06 Feb '08

06 Feb '08

For the upcoming Satellite Simulated Emergency Test, remember that pass times for AO51 repeat every 5 days, so you can estimate pass times from your mobile at any time for a few months using the table below taped to your dashboard: EASTERN Standard Time 07Feb 13Feb 19Feb 25Feb 02Mar ----- ----- ----- ----- ----- 0835 0800 0720 0820 0740 0855 1950 1910 1830 1930 1850 2010 Just locate the column with the date closest to today's date and then move right or left the number of days to today's date. The table wraps around both ways. Passes will be as shown local time. For example, when the SSET begins on 9 Feb, the morning passes are at 0720 and 0855 EST, etc. There are three other similar tables for each time zone on the SSET page: http://www.ew.usna.edu/~bruninga/sset.html There are also tables for each time zone for GO32 on the GO32 APRS Operations page. http://www.ew.usna.edu/~bruninga/GO32-ops.html The purpose of the SSET is to demonstrate your ability to get a message out from your mobile or portable station via one of the Amateur Satellites. For the APRS satellites, PCSAT-1, ARISS, and GO32, not only should you then receive your Email message back to you, but your message and position/status should also appear on the PCSAT/GO32 or ARISS Web pages: http://pcsat.aprs.org http://www.ariss.net Good luck.

Hello folks, Could the recording of what is believed to be Prospero X-3 on the Amsat-UK website on 137.560Mhx in fact be from one of the Orbcomm satellites ?. Just a thought. Easily checked, by running the free Orbcomm software and having a listen to the telemetry. 73 John. <la2qaa(a)amsat.org> 73 John. <la2qaa(a)amsat.org>
