AO-91 and circular polarization?
by Todd W Deckard 11 Mar '18

11 Mar '18

Would it be correct to use a CP antenna on the L-band uplink for AO-91? If so which polarization? Just purchased an ICOM X-2 on ebay that gets me 1.2ghz and the temps are getting civilized so it’s about time to get back on the air ... My elev. over azimuth system is already swinging more mass than it was geared for and i’m looking to cook up a small antenna that doesn’t add too much straw to the camel. I would like to go Helical just because ... if anyone has an alternate suggestion I’d listen to any and all. Thanks Todd KE0CMD Sent from my iPhone

Strange orbit
by Pedro Converso 11 Mar '18

11 Mar '18

Yesterday some not ham satellites were launched, classified as O3Bxx. They have equatorial 7800 Km height orbits, with amazing coverage. Take a look at http://amsat.org.ar/pass.htm?satx=43232 and click on icon to see coverage. Wish some day we hams could have that kind of orbit. 73, LU7ABF, Pedro

Symptoms of TS-2000 birdie
by Burns Fisher 11 Mar '18

11 Mar '18

Hi all, I'm wondering if a curious phenomenon that I have seen is related to the infamous TS-2000 SO-50 birdie. I thought I would see if I could make a contact on SO-50 with my TS-2000 even knowing about the birdie. I can certainly hear others during parts of the pass. I did not hear anything so I punch up the arming tone, and oddly, I could hear both the tone (120-something?) and my voice totally clearly on the downlink frequency. I seriously doubt that I was getting into the satellite at that point. So what is the symptom of the birdie? I thought it was just blanking out the Rx band over a certain range. Any thoughts? Thanks and 73, Burns WB1FJ

Grid EL58hx Activation 2018
by Clayton Coleman W5PFG 11 Mar '18

11 Mar '18

(Venice, LA, USA) Wyatt Dirks, AC0RA, and Clayton Coleman, W5PFG will travel to the mouth of the Mississippi River in far Southeast Louisiana to activate maidenhead gridsquare EL58hx on Memorial Day weekend, 2018. The primary activities will be on the 6m band and OSCAR satellites. This will be Wyatt’s first activation of EL58 in Louisiana and Clayton’s second. Both operators have conducted multiple, successful portable activations over the years, with Wyatt activating over 200 grid squares and Clayton over 150. Dates, the operating location in the grid, and transportation arrangements are confirmed. The activation is scheduled to begin after 23:00 UTC on May 25 and will conclude by 20:00 UTC on May 27. All 6m operations will use the callsign AC0RA. All satellite operations will use the callsign W5PFG. HF operation will occur during slower periods on 6m and when there are no satellites in view. Those wishing to confirm HF contacts must do so via ARRL’s Logbook of the World (LoTW.) 6m and Satellite confirmations will be available following the expedition on LoTW in addition to paper QSL’s accompanied with a Self-Addressed, Stamped Envelope (SASE.) Further information will be released prior to the expedition. For general inquiries contact Clayton, W5PFG, at w5pfg(a)arrl.net. For 6m operational questions contact Wyatt, AC0RA, at dirkswyatt10(a)gmail.com. -- 73, Clayton W5PFG

AMSAT NEWS SERVICE ANS-070.01 The AMSAT News Service bulletins are a free, weekly news and infor- mation service of AMSAT North America, The Radio Amateur Satellite Corporation. ANS publishes news related to Amateur Radio in Space including reports on the activities of a worldwide group of Amateur Radio operators who share an active interest in designing, building, launching and communicating through analog and digital Amateur Radio satellites. The news feed on http://www.amsat.org publishes news of Amateur Radio in Space as soon as our volunteers can post it. Please send any amateur satellite news or reports to: ans-editor at amsat.org. In this edition: * Robertsville Middle School Students Will Send a CubeSat into Space * Call for Volunteers - Dayton Hamvention * Maidenhead Grid EL58hx Activation Memorial Day Weekend 2018 * FJ, St. Barthelemy Operations April 19-27 * AMSAT-OSCAR 92 * Send Your Name to the Sun Aboard the Parker Solar Probe * Satellite Shorts From All Over SB SAT @ AMSAT $ANS-070.01 ANS-014.01 AMSAT News Service Weekly Bulletins AMSAT News Service Bulletin 070.01 >From AMSAT HQ KENSINGTON, MD. March 8, 2018 To All RADIO AMATEURS BID: $ANS-070.01 Robertsville Middle School Students Will Send a CubeSat into Space In November of last year, a team of Robertsville middle students, educators, and Oak Ridge scientists submitted a proposal to NASA for their Cube Satellite Launch Initiative (CSLI) in hopes of sending a student-designed nanosatellite named, "RamSat" into space. NASA's CSLI provides opportunities for small satellite payloads built by various schools and non-profit organizations to fly on upcoming launches. NASA provides CubeSat developers a low-cost pathway to conduct scientific investigations in space, enabling students, teachers, and industry partners to obtain hands-on development experiences. In a letter received on March 2, 2018, we learned that our proposal for RamSat was accepted for participation in the CSLI, an initiative intended to provide launch opportunities during 2019, 2020, and 2021. CubeSats are auxiliary payloads on planned NASA, other U.S. Government, or commercial space flight missions, or deployments from the International Space Station. We learned that our payload is one of 21 satellites selected or prioritized for participation in the ninth CSLI selection. Our acceptance was also announced on NASA's website as RamSat, an education mission to develop and implement a middle school STEM curriculum for building a CubeSat. Peter Thornton, one of the RamSat team leaders from Oak Ridge National Laboratory stated, "This is such an exciting opportunity for the students! They will now have the chance to design, build, carry out and own a satellite mission. They will be the mission scientists, the communication specialists, and the logistics experts. They will calculate orbits, learn to aim their satellite camera at selected targets on the ground, radio their commands to RamSat, and receive and interpret the digital data streams broadcast by RamSat, containing imagery and all the other important data gathered on- board. They'll be working as a team to identify and solve problems, and they will be working with NASA professionals to integrate RamSat into the launch and deployment missions. I can't think of a more exciting project to ignite the students' curiosity and passion for science and engineering." The CSLI ride-share launch features spacecraft called nanosatellites. CubeSats are sized in units, and one unit (1U) is 10 cm x 10 cm x 10 cm. To participate in the CSLI program, CubeSat investigations must be in alignment with NASA's Strategic Plan. The Robertsville Middle School proposal aimed to demonstrate alignment by creating student-driven STEM-based lessons addressing educational development needs relevant to NASA's strategic goals. The students' targeted mission for their RamSat is to send a small camera and radio encased in a 2U nanosatellite that will relay data and images from space back to earth. With this information, students will study reforestation patterns of vegetation lost in forest fires. The student mission arose in response to a real-world connection they had to the Gatlinburg fires last year.

[ANS Thanks Clayton Coleman, W5PFG for the above information] --------------------------------------------------------------------- FJ, St. Barthelemy Operations April 19-27 AI5P, N0KV, W0ZA and WD0E plan to operate from Pointe Milou, St. Barthelemy Island (IOTA NA-146/Grid Square FK87) from April 19-27, 2018. Operation will be on 80-10 meters (SSB/CW/ RTTY) with satellite operation by WD0E. Conditions may largely limit most activity to 20 meters and down. Operating 160 meters is being considered; however, no antenna option is yet finalized. Satellite operation will take place on several satellites. A satellite and pass schedule will be announced on the AMSAT-bb in advance. Equipment includes three Elecraft K3's and two 500 watt Elecraft amps. Antennas include a SteppIR crank IR vertical for 80-10 meters, a folding hexbeam by Folding Antennas (Germany) on 20-10 meters, LPDA's on 20 and 17 meters and verticals on 30 and 40 meters. Operation will be as continuous as conditions warrant. The Colorado operators have decided to use FJ/N0KV as their callsign while AI5P will be active as FJ/AI5P. FJ/N0KV logs will be updated to LOTW while Rick's logs (FJ/AI5P) will not since he continues to be an analog guy with an actual key and pen/paper log. Paper QSLs will be available from both N0KV and AI5P direct and via the bureau. Further: For satellite operation we plan to be on as many passes of as many satellites as possible focusing on the evening hours. Equipment will be an IC 910 and Arrow. On Montserrat in 2015 we were on FO-29 only. For St. Barts we will also operate some FM satellites. We will assemble a pass plan before we go and post it to this -bb. We will stick to that plan as much as possible but of course condi- tions may cause us adjust on the fly. The operating location has good visibility to the horizon from about the NW through N and E to the SE. Other directions are somewhat obscured. QSLs handled as written above.

Greetings everyone, I just joined AMSAT this week and look forward learning more about amateur radio satellites. I have been working the FM satellites with an Arrow II antenna and two HT's in full duplex mode for the last 6 months or so, finally decided join up so I could learn more and mebbe get a little help in branching out to the SSB satellites. I have had the pleasure of a number of QSOs with a few of you... KK6OTJ, KB6LTY, W7QL, WD9EWK, AF7H, WB7VUF, N3GS, K5IX, K5ND, WC7V, WW5TT and AL6D among others. Looking forward to more! 73, Bob, N6REK
