07 Oct '13

Any school club stations planning to be active on the satellites for the fall School Club Roundup (October 21st - 25th)? I know my alma mater (Michigan State University, W8SH) has the equipment, but I'm not sure it's been used in years or if anyone there knows how to use it. 73, Paul Stoetzer, N8HM Washington, DC

Ham Radio News on page 2 reports on AMSAT's filing for clarification on the status of amateur satellites under new US Government regulations. VHF Plus columnist Joe Lynch, N6CL discusses the filing in more detail on page 89. Other news of amateur radio in space in this issue include: + News of the HamTV transmitter launched to the ISS is covered on page 88. + OSCAR 7 gets mention on page 2. + Video from the NASA Cubesat workshop on page 90. + The 2013 AMSAT Space Symposium in Houston is mentioned on page 91. [ANS thanks CQ Magazine for the above information] --------------------------------------------------------------------- Cubesat Spaceport Coming to Jacksonville, Florida NASA awards first CubeSat-class launch services contract (30 September 2013) NASA has selected Generation Orbit Launch Services Inc., of Atlanta, Ga., to provide a CubeSat-class launch via the NASA Launch Services Enabling eXploration and Technology (NEXT) contract. NEXT is an element of a strategic initiative led by NASA's Launch Services Program (LSP), focused on assuring long-term launch services while also promoting the continued evolution of the U.S. commercial space launch market. The NEXT launch service will deliver three 3U-configuration CubeSats to a 264-mile orbit via a Federal Aviation Administration (FAA)- licensed launch aboard Generation Orbit's GOLauncher 2 rocket in August 2016 from Cecil Field Spaceport in Jacksonville, Fla. NEXT is a pathfinder contract for future acquisitions of launch services for low-cost and/or high-risk tolerant payloads. It sets the groundwork for LSP to utilize different contracting strategies that tailor the spectrum of government insight and approval based on the risk tolerance of the spacecraft. The total cost value for the NEXT launch service is approximately $2.1 million. This new contract resulted from a competitive award set-aside for small businesses only. GOLauncher 2 will launch CubeSats as the primary payload via the NEXT contract due to their ability to tolerate the higher risk of a new nano-class rocket while also helping to provide additional opportunities for the many CubeSats awaiting launch opportunities under NASA's CubeSat Launch Initiative (CSLI).

Chamitoff, KD5PKZ and Ronald J. Garan KF5GPO are leaving the agency. Chamitoff is joining the faculty of Texas A&M University in College Station, Texas, and the University of Sydney in Australia. Garan will work on a range of new entrepreneurial and humanitarian efforts. "Greg and Ron will certainly be missed by the Astronaut Office," said Bob Behnken, KE5GGX, NASA's chief astronaut. "Greg's passion for sharing the spaceflight experience will serve him well as he begins a new adventure in academia and continues to inspire the next generation of innovators and explorers. I'll miss Ron both as a contributor to our office and as a classmate. The entire office is grateful for their service to NASA." Chamitoff began his 18-year NASA career in 1995 as a space shuttle guidance and control officer in mission control at the agency's Johnson Space Center in Houston. He was selected as an astronaut in 1998. He flew in space twice, in 2008 as a flight engineer and science officer for Expeditions 17 and 18 aboard the International Space Station, and as a mission specialist during STS-134 in 2011, the penultimate shuttle mission. During his most recent mission, Chamitoff participated in two spacewalks to complete assembly of the International Space Station, taking part in the installation of the Alphamagnetic Spectrometer. He has spent more than 198 days in space. Garan, who joined the agency in 2000, is ending a 13-year NASA career that included more than 178 days in space and four spacewalks. Garan flew in space twice, first in 2008 as a space shuttle Discovery mission specialist on STS-124, and again in 2011 aboard the International Space Station as a flight engineer for Expeditions 27 and 28. Garan retired from the Air Force as a colonel in 2009 after 25 years of service. He has logged more than 5,000 flight hours in more than 30 aircraft types. He recently served within NASA’s Open Government Initiative.

In the past this has included satellite development, satellite history, ground stations, antennas, hardware devel- opment, software. We find that some items related to SDR, VHF, UHF, and microwave operating or roving are directly applicable to satellite operations. Educational outreach has been identified as a key area which AMSAT may use to leverage launch opportunities. The Journal welcomes news, photos, and articles of ARISS contacts, University research and development, and STEM programs. Amateur satellite operators have the gear and expertise to also receive interesting transmissions from non-amateur spacecraft and EME. Articles discussing how this is done are useful to our readers discovering they can do more with the station they have built. The deadlines for each AMSAT Journal, which is published six times per year, are: ISSUE DEADLINE --------------------- -------------- 1. January/February December 20 2. March/April February 20 3. May/June April 20 4. July/August June 20 5. September/October August 20 6. November/December October 20 Our editors will work with you to finalize your article for publi- cation. Please send the following: 1. Electronic copy of your article in any of the popular word pro- cessing formats (MS-Word, OpenOffice, plain-text Notepad, etc.) PDF files containing a custom layout with embedded graphics can- not be used. 2. Your text must be single column wide. You do not need to do any formatting to make it appear in the 3 column layout of the fin- ished magazine. We have to remove all your hard work of pre- formatting before publication so save yourself the problems of trying to get columns to line up, etc. 3. You may send a copy of your article with the photos where you recommend they appear with the text but this is not the version that will be published. This gives the editors some cues to maintain continuity with photos/captions and text. 4. We require a text-only copy your article. Embedded photos will not publish during the layout process. You can leave in a ref- erence in the text related to the photo associated with that point in your article as shown here: ... text ... text ... text ... text ... text ... text ... ... text ... text ... text ... text ... text ... text ... (Insert Graphic 1234 here) Figure 2. Sample Lorem Ipsum Text ... text ... text ... text ... text ... text ... text ... ... text ... text ... text ... text ... text ... text ... 5. Send a separate text file with the captions to each of the graphics. 6. Send photos and graphics as separate files. Use as high resolu- tion pixel format as you can. The preferred graphic format for the Journal is JPG. The Journal can publish additional graphic formats including GIF, BMP, and PNG. Contact the editor before submitting these formats. Note that a photo which appears nicely on a web page does not publish well on the high resolution finished magazine product. Photos from digital cameras in mega-pixels work well. You do not need to compress or shrink the file for us. 7. If you use printed circuit board software or schematic drawing programs we can usually import a PDF copy of the diagram into the publishing software. Please do not send PDF formatted copies of the article however. 8. We can freely republish papers you have submitted to prior AMSAT Symposiums. If you have a good idea that you would like to get out the AMSAT Journal is an excellent way to expand your audience. We find that 200-300 copies of the Symposium Proceedings are dis- tributed. The AMSAT Journal reaches 4000 additional satellite operators. 9. If your article was previously published in another AMSAT organi- zation's Journal, or magazine (QST, CQ, CQ VHF, etc.) we will work with you to secure the permission to republish your work. Our Journal editors will be happy to work with you to assist getting your article published. We can help you develop an idea into a fin- ished article as well as a ready-to-print submission. Ask us via e-mail and we can get rolling with your article. During the preparation process it is quite likely that an editor working on the article might personally contact you with questions and suggestions. Those suggestions might include extra pictures or maybe additional references, keeping in mind that some readers might not have an extensive background on the topic being discussed. Send your articles and photo/graphics files as attachments to e-mail to journal(a)amsat.org.

Re: Crushcraft A144-10T "VHF Twist" Antenna
by WILLIAMS MICHAEL 05 Oct '13

Joe, I agree with Stefan's email below (VE4NSA). Set it up for LHCP. VO-52 seems very LHCP as well as AO7. I used LHCP on 2 meters and RHCP on 70 cm for years with good success. I recently added polarization switching to my old KLM. I didn't have success on the first try. Compared with my reference signal before and after, the project at first attenuated the signal.

Try it before you spend more money. It probably will be a good antenna for your attic. No water issues at that location. Set it up for LHCP and with the current satellites it will work most of the times just fine. Why pay big bucks for a "newer" one if this will work for you. 73, Stefan VE4NSA

Re: Digital QRM on FO-29 (DF opportunity!)
by Robert Bruninga 05 Oct '13

05 Oct '13

Wow, a GREAT DF opportunity and exercise. The Doppler info is there to determine its location. Just plot the doppler and note the center point and draw a line of bearing through it. Combine with others and find the source. heh heh... though, complicated by having to subtract out your own... But we should develop these techniques. They are the basis of all of the original Search And Rescue satellite systems. In fact!!! Why not get a few hams in a few areas of the country to operate a CW carrier (at low power) at a known frequency in 4 corners of the US and let evreyone practice their techniques. This way, we learn how to do it on a known signal. Just a thought.
