More North Korea Satellite and Launch Info
by Larry Koziel K8MU 12 Dec '12

12 Dec '12

I found several articles that may be of interest on a website "devoted to analysis of North Korea." The site <http://38north.org/> is a program of the US-Korea Institute at SAIS (School of Advanced International Studies, Johns Hopkins University). The first was published in April, and has as detailed a description and photographs of what was probably the engineering prototype of the satellite that was successfully orbited: http://38north.org/2012/09/nhansen091212/. The second, published shortly before the launch, discusses GeoEye satellite imagery that shows preparations at the launch site: http://38north.org/2012/12/sohae121112/. A third article shows the launch trajectory and has a link to a KMZ file that illustrates approximately the first half-orbit that can be viewed in 3-D with GoogleEarth: http://38north.org/2012/04/tongchang041012/ <http://38north.org/2012/04/tongchang041012/>.

Good discussion of using two HF rigs with transverters for satellite comms
by Alan 11 Dec '12

11 Dec '12

All, Flex has an interesting article on using two rigs for full duplex operations using SATPC32. http://support.flexradio.com/Downloads.aspx?fr=1 Look for: A Full-Duplex VHF-UHF Satellite System using FLEX radios While some of the article is specific to Flex radios, there is an excellent discussion of considerations for transverter LO frequencies which is relevant to most rigs. 73s, Alan WA4SCA

Lithium Batteries and USPS
by Bruce 11 Dec '12

11 Dec '12

I was just at the post office in Houston shipping a package to Florida and they asked me there were any lithium batteries in the package. I said no and asked why. The postal worker said they no longer take packages with lithium batteries unless they are in a laptop or cell phone. I asked what about in a radio and she said no. hmmmmm 73...bruce -- Bruce Paige, KK5DO AMSAT Director Contests and Awards ARRL Awards Manager (WAS, 5BWAS, VUCC), VE Houston AMSAT Net - Wed 0100z on Echolink - Conference *AMSAT* Also live streaming MP3 at http://www.amsatnet.com Podcast at http://www.amsatnet.com/podcast.xml or iTunes Latest satellite news on the ARRL Audio News http://www.arrl.org AMSAT on Twitter http://www.twitter.com/amsat

FT-817 Sat-CAT Interface Boards and Kits
by Mark Spencer 11 Dec '12

11 Dec '12

Hi All, A while back, an article about a FT-817 Satellite Control Interface was published in QST. There were numerous requests for boards and kits on the project. There is a small quantity of the boards and kits available but the procurement information didn't make it in the original article. The raw boards are available for $20, and a kit with the board, parts and programmed PIC is available for $35. You can send an email to Debra Johnson at ARRL HQ and order them from her (djohnson(a)arrl.org). The proceeds from this effort is going back to AMSAT and the Fox birds, so anything above and beyond these amounts (which are basically at cost) will go into space as part of Fox. Questions? Let me know mspencer(a)arrl.org. Thanks, Mark Mark Spencer, WA8SME Education and Technology Program Director ARRL, the national association for Amateur RadioTM 43 Pinelock Dr. Gales Ferry, CT 06335 860-381-5335 860-460-1139 (cell) mspencer(a)arrl.org
