[amsat-bb] Re: Rotation of NIWAKA
Thank you David and Joe. It may be air resistance effect. I will consider again. -- Takushi, JA6AVG - Original Message - Dear Satellite expert, Satellite NIWAKA increases its rotation speed. I appreciate if you know the reason. http://www.fit.ac.jp/~tanaka/fitsat.shtml Thank you -- JA6AVG, Takushi Tanaka ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author.

[amsat-bb] New Cuban Stations on Satellites
Hello everyone, As many of you should already know, now we have two new Cuban Amateur Operators on FM Satellites. Recently CO7WT and CM2XN have finally achieve their firsts QSO on SO-50 Satellite. This may look simple, but for a Cuban Ham this is a great success, after many weeks of antenna building, equipment adjustments and learning, this two fellow hams enjoy of the amazing opportunity of make a QSO on a FM Transponder Satellite. They know there is a lot more of operating skills to learn and they are very happy to do so. This apparent little success is a great success and motive of pride for the Cuban Satellite Group named GROS, Grupo de Radioaficionados para Operaciones Satelitales (Ham Radio Group for Satellite Operations ...a very free translation...) One of the many objectives of our Satellite Group is to promote this part of the hobby to our fellows ham. Many Cubans hams does not have the required equipment to successfully make a satellite QSO, but with the help of the Group they can put their technical skills to work and success. Few other Cuban hams has the required gear but they usually thought working a satellite is too difficult. However, with these little success the Group can show to the rest of the Cuban ham community how two stations using inventiveness and perseverance worked a FM Satellite, and perhaps those hams with the proper equipments finally decide to get on the air and activate new grids. CO7WT, Pavel is the Group's Technical Vice-Coordinator. And CM2XN, Jose, is a Group new Member since 1 month ago. The Group continues with the VHF Nets in Havana Province two times a month on Fridays and we are working on extend it to a National Net on HF one time by month on the future. The Group's First National Meeting continues postponed due to logistical arrangements but it is still as a priority to the Cuban National Amateur Radio Federation (F.R.C. - Federación de Radioaficionados de Cuba) and we have their full support. You are free to ask any question or send comments regarding the Cuban Satellite Group to any Member of the Coordination Board as well to any member in general. - CO6CBF, Hector, Vice-Coordinator (co6...@frcuba.co.cu) - CO7WT, Pavel, Technical Vice-Coordinator (pa...@conas.cu) - CM2ESP, Raydel, Coordinator (cm2...@frcuba.co.cu) There is a video (http://www.youtube.com/watch?v=eocmIubIBQ4) of Hector, CO6CBF, at the 2012 AMSAT Space Symposium talking about how a Cuban Ham operate a satellite. Thanks to Patrick WD9EWK and AMSAT for such opportunity!!! All the best from Cuba and thank all of you for your help, patience and understanding. 73, Raydel, CM2ESP GROS Coordinator PS: Sorry if I write something wrong, my english is not perfect. ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] CO7WT QRV on FL11 this nigth on SO-50
Hi OMs I (CO7WT) will be active this nigth (12-feb-3012 ~0130Z) on the SO-50 bird. It will be an aprox. 40 degrees pass here, with my setup I have shure coverage of about 20 degrees and up... QSL is 100% via manager ( N2CQ ) and will be ready a few days after the contact. I'm ready for any scheduled contact, always in non office hours... If you are interested, please drop me an email. Remember, I operate semi-portable, with base rigs and a homebrew arrow in my hand in my QTH's roof. I'm new to sats, so any suggestion, critics, etc... are always welcomed.

[amsat-bb] SpaceTrack.org upgrade 20 February 2013 at 12:00 PST
If you are getting your keps from SpaceTrack, you may see some changes soon. The following is the latest from Vandenburg: ** We are pleased to announce that we will upgrade the current www.Space-Track.org on Wednesday, 20 February 2013 at 12:00 PST to add the look and functionality that matches what is now on https://beta.space-track.org. The bulk file downloads from our current Space-Track site will continue to be available to scripters for a limited time after the upgrade using established URLs. This upgrade will vastly improve how the Space-Track User community interacts with orbital element sets, the satellite catalog and conjunction data. With a robust Representational State Transfer (REST-ful) Application Programming Interface (API), scripters will be able to get the latest data available, customized for their purposes. Here are just a few of the new features that will become part of the upgraded www.Space-Track.org: - A streamlined and intuitive user interface that is easier to navigate and allows simple searches - A robust help and documentation section - Favorites lists to identify logical groupings of catalog objects that Users can monitor via the web interface or with the site's API If you have production scripts that currently use beta.space-track.org, we recommend that you change your scripts to point at www.Space-Track.org on or after 20 February 2013. If you have scripts that screen-scrape or download text/zip files from the current yellow-colored legacy www.Space-Track.org, they will continue to perform correctly for a few months, but we recommend that you quickly transition your scripts to take advantage of the new API. Documentation is available under Help to assist you, as well as the API query builder tool on the upgraded site. We have also started sharing information about Space-Track's new features on tumblr, facebook and twitter, so please engage us on your favorite social media platform. Our sites are http://space-track.tumblr.com, http://www.facebook.com/SpaceTrack andhttp://www.twitter.com/SpaceTrackOrg We understand that any significant upgrade has the potential to cause frustration for our user community and we apologize if this creates any adjustment problems for you. For help or clarification, please email us at ad...@space-track.org. Thank you, The www.Space-Track.org Team ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author.
