antenna choices
by mikflathead＠aol.com 18 Feb '18

18 Feb '18

Hello group. In the coming months (when the weather breaks) I am going to be installing antennas for 2, 435 and probably 1269. I purchased a Cushcraft A144-11 beam at a recent hamfest (the price was right). I would rather re purpose than spend big dollars on antennas. My question is should I run a single antenna on 2 or try to get a pair of these and phase them? Or maybe add elements on this boom to get circular. Or just use this antenna by itself? I hope this makes sense. I do not have a 435 antenna at the present time but do have a few 1296 loopers. Thanks hope to be on the birds in a few months. Mike

TY 6 identified and some info on PICSAT
by Nico Janssen 18 Feb '18

18 Feb '18

All, Detailed doppler measurements show that TianYi 6 (TY 6) is object 43158, 2018-008D. TY 6 is a payload in the satellite QuanTuTong 1 (QTT 1). The TLEs for PICSAT have not been stable since February 14. New doppler measurements show that PICSAT is now object 43132, 2018-004X. But its separation from object 43133 is only a few seconds. The FM repeater in PICSAT has been tested and appears to work well. 73, Nico PA0DLO

Ok, got it. The APRS email method is built into the APRS-IS, there is no "server", per se. Instead you just send a properly formated aprs message as shown below: http://www.aprs-is.net/email.aspx The PTT capability of direwolf is (I believe) documented in the user manual, and there are plenty of web sources dealing with creation of a ptt circuit for the baofeng. Almost too many, actually.

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: * Upcoming AO-92 Operations Schedule * SatPC32 12.8d is released * ARRL 2018 Teacher Institute to Include Amateur Satellites, Telemetry * Kettering University Student Brings Ham Radio Hobby, Expertise to Campus * AMSAT Argentina Balloon Flight Completes 2nd Trip Around the World * AMSAT Phase 4 Ground Station Update: FPGA, RFNoC, SDSoC * AA5UK Announces March 1 Cayman Island Satellite Activation * Phase 4 Ground Weekly Report! * Volunteer Opportunity - Openings for News Service Rotating Editor * ARISS News * Satellite Shorts From All Over SB SAT @ AMSAT $ANS-049.01 ANS-049 AMSAT News Service Weekly Bulletins AMSAT News Service Bulletin 049.01 >From AMSAT HQ KENSINGTON, MD. February 18, 2018 To All RADIO AMATEURS BID: $ANS-049.01 Upcoming AO-92 Operations Schedule AO-92 operations are scheduled among the U/v FM repeater, L-Band Downshifter, Virginia Tech Camera, and the University of Iowa's High Energy Radiation CubeSat Instrument (HERCI). For the week of 18 - 24 Feb 2018, the following mode changes are scheduled: Approximately 0200UTC 18Feb we will enable the L band uplink for ~24 hours Approximately 0255UTC 20Feb we will enable high speed data in order to download from the HERCI experiment for 40 minutes Approximately 1540UTC 21Feb we will enable high speed data in order to download from the VT camera for 40 minutes Approximately 0215UTC 22Feb we will enable high speed data in order to download from the HERCI experiment for 40 minutes All other times the U/v repeater will be open continuously. [ANS thanks Drew KO4MA for the above information] --------------------------------------------------------------------- SatPC32 12.8d is released The English version of SatPC32 12.8d is now available for download on the author's web page. http://www.dk1tb.de/downloadeng.htm Here's What's New in the 12.8d version: 1. The CAT commands of the IC-9100 have been extended again. The program now also controls the DV mode (DV for 'Digital Voice') of the radio. The operating mode must be entered as DV in the file Doppler.SQF. With the FT-817 the program now additionally supports the CWR mode. 2. All SatPC32 programs now process significantly larger Keplerian element source files. Especially because of the numerous new Cubesats, the number of data sets contained in the source files has increased significantly. For example the file Cubesat.txt currently contains data for nearly 400 satellites. The previous version of the SatPC32 programs could only read up to 320 data sets (only SatPC32 itself up to 500). All SatPC32 programs have been expanded to handle sets of up to 1500 satellites. 3. In all programs (SatPC32, SatPC32ISS, Wisat32, WinAOS and WinListen), the list of satellites contained in the source file ('Available' list in menu Satellites) is now displayed in alphabetical order to facilitate locating individual satellites. 4. The program SatPC32ISS now also allows the creation of up to 12 satellite groups. The new Cubesats have also increased the number of 'in-band' satellites. Originally, in-band operation in amateur radio was only available at the ISS. 5. In order to accelerate a change between the individual satellite groups, the 'Groups' window can now be called up by clicking on vacant areas of the main window, except in the Satellite menu. Such free positions are located on the right and left of the frequency window. Editing the groups (create or delete a group, add or remove satellites) can only be done in the Satellites menu. 6. In the Satellites menu the data sets of the satellites contained in the active source file can now be displayed. When called, the data set of the currently selected satellite is displayed. The feature helps you to immediately know the identifier of the satellite. This allows you to add an entry to the file 'AmsatNames.txt' (menu '?' 'Auxiliary files'), so that the satellite can be displayed in the entire program with its AMSAT name or with a user defined name. 7. The program has improved control of the sub-audible tone required by some satellites. For many years SO-50 was the only such satellite. Switching sub tone was no issue. Now we have several (AO-85, AO-91, AO-92) The program can now automatically switch the sub tone on/off when switching between PL tone satellites and others, changing between u/v and v/u satellites, changing the group, closing the program etc. 8. In addition, numerous minor changes and error corrections have been made some people have complained about the difficulty of manually adding a new satellite and its corresponding tuning information. The Programs menu can now launch the W9KE DopplerSqfEditor to aid this process. Please read the instructions before installing or updating the program. You probably want to run the DataBackup program before updating an existing version. Existing registration codes work with the new version. Thanks to Erich Eichmann DK1TB for donating this software to AMSAT. Sale of registration codes and CDs is a major fund raiser for AMSAT. And thanks to Erich for providing user support on amsat-bb and updating the program for 20 years. No other satellite tracking program provides such comprehensive radio Doppler tuning. [ANS thanks Wayne W9AE for the above information] --------------------------------------------------------------------- ARRL 2018 Teacher Institute to Include Amateur Satellites, Telemetry As part of its educational outreach through the Education & Technology Program (ETP), ARRL will offer three sessions of the Teachers Institute on Wireless Technology this July. The week-long workshops will be held at ARRL Headquarters in Newington, Connecticut, and in Dayton, Ohio — hosted by the Dayton Amateur Radio Association (DARA). The Teachers Institute (TI) is an expenses-paid, professional development seminar that provides teachers at all grade levels with tools and strategies to introduce basic electronics, radio science, space technology, and satellite communication, as well as weather science, introduction to micro-controllers, and basic robotics in their classrooms. The Teachers Institute curriculum is designed for motivated teachers and other school staff who want to learn more about wireless technology and bring that knowledge to their students. The goal of the TI program is to equip educators with necessary foundational knowledge and — through hands-on learning — generate the inspiration for teachers to continue exploring wireless technology and adapt what they learn to their classroom curricula. Interested educators can apply online. The $100 enrollment fee is refunded for applicants who are not selected. A qualified applicant must be an active teacher at an elementary, middle, high school, or community college/university, or in a leadership or enrichment instruction role in an after-school program. Session Location Dates Instructor TI – 2 Newington, CT July 9 – July 12 Matt Severin N8MS TI – 1 Dayton, OH July 16 – July 20 Larry Kendall K6NDL TI – 1 Newington, CT July 23 – July 27 Tommy Gober N5DUX Topics covered in the TI-1 “Introduction to Wireless Technology” workshop include basic electronics, radio science, microcontroller programming, and basic robotics. Among other activities, participants will learn how to solder and practice by building a small project. They’ll also learn basic circuit concepts and learn how to use basic test equipment. In addition, TI-1 attendees will learn about Amateur Radio, take part in a hidden transmitter hunt, see demonstrations of Amateur Radio satellite communication, and build and program their own simple robots. The TI-2 “Remote Sensing and Data Gathering” workshop will concentrate on analog-to-digital conversion and data sampling. Participants will receive telemetry from Amateur Radio satellites and apply it to math and science topics. TI-2 participants will also construct a marine research buoy equipped with environmental sensors, build a microcontroller to sample the data, configure it for Automatic Packet Reporting System (APRS) transmission, and receive and upload data to a spreadsheet for analysis. Holding an Amateur Radio license is not required for the “Introduction to Wireless Technology” workshop (TI-1), but one is required by those planning to attend the advanced “Remote Sensing and Data Gathering” workshop (TI-2), and applicants to the advanced workshop must have completed TI-1. The grant to attend a TI covers transportation, hotel, and a modest per diem allowance to cover meals, instructional resources, and a resource library of relevant ARRL publications. Graduate credit is available through Fresno Pacific University, which may be applied to satisfy professional growth requirements to maintain teaching credentials. The class is self-contained, and participants are expected to be able to complete all requirements during the class time. Graduate credit forms may be requested at the end of the Teachers Institute. For more information, contact Ally Riedel ariedel at arrl.org at ARRL Headquarters. [ANS thanks ARRL Headquarters for the above information.] --------------------------------------------------------------------- Kettering University Student Brings Ham Radio Hobby, Expertise to Campus Ruth Willet ‘21 has always been fascinated with Morse code, especially when researching World War II. That fascination grew into a hobby, and she soon found herself engrained in the amateur radio - more commonly known as ham radio - community. Willet, who is double majoring in Mechanical Engineering and Engineering Physics, first got licensed in June 2015 as a ham radio operator because of her interest in Morse code. She soon upgraded her license in order to explore more aspects of the hobby. Other hams know Willet as KM4LAO (Kilo Mike Four Lima Alpha Oscar), the call letters of her government-issued ham radio license. “It’s such a special hobby because there’s so many people that want to get to know you and want to help you learn and grow. It really has enabled me to mature into who I am today. I have gained incredible friends from across the globe,” said Willet, a Georgia native. “This hobby supplements very well what I’m doing at Kettering because it has application in a lot of different subjects. I love seeing the practical application of electronics, solar weather and the way radio signals propagate around the globe. I am thrilled by the fact that I can talk to someone who’s driving down the interstate 10 miles away, bounce signals off of satellites to have conversations hundreds of miles away, or talk around the world to someone in Africa. It’s fascinating. You really learn a lot.” Willet had to pass an exam given by the Federal Communications Commission (FCC) in order to receive her call sign and be allowed to operate on the air. The three levels of Amateur radio licenses from entry-level to most advanced are Technician, General, and Amateur Extra. Willet upgraded to the Amateur Extra level license before she graduated from high school. Willet can use a hand-held radio to talk with someone across town, or she can use a more robust radio that enables her to talk around the world by reflecting her transmitted signal off the ionosphere. There are fast-paced competitive events she participates in where she is supposed to talk to as many people as possible within 24 hours. She can operate in multiple ways, including Morse code, voice communication or digital (which is similar to texting through ham radio). “The fun thing is that’s only the start. Amateur radio satellites are orbiting the earth. You can bounce off the satellites and talk to people halfway around the world,” Willet said. “We can also use our skills to assist in emergency situations. For example, when Hurricane Irma recently hit in Puerto Rico, amateur radio operators were some of the only people who could communicate from the island to the outside world.” In 2016, Willet also participated in National Parks on the Air, a worldwide event organized by the American Radio Relay League. Since 2016 was the centennial of the National Park Service (NPS), hams wanted to help celebrate history by getting people to national parks, seashores, monuments, and more. Ham radio operators went out and set up portable radio stations, got on the air, and helped other hams around the world conduct “virtual visits” to parks across the country. When Willet came to Kettering University, she knew she wanted to continue her ham radio activities. Kettering was appealing to her for the small classes and the close-knit campus feel, on top of the co-op experience. “After coming for the LITE (Lives Improved Through Engineering) summer program and seeing how personal everybody was at Kettering I just really felt like it was a great fit. And I can’t turn down the co-op experience,” Willet said. “I was first interested in Mechanical Engineering because my grandfather had a book about basic machines and how they work. I was fascinated with levers to complicated gears. Then senior year of high school I took Physics and I loved it. Being able to see the effects of basic physics on daily life was very interesting to me. I’m learning as much as I can at school and exploring opportunities both inside and outside the classroom so that I can make the most of my time here.” She has found that the skills she learns in classes go hand in hand with her amateur radio hobby. Willet plans to start up an Amateur Radio Club on campus in the spring 2018 term to get more students interested. “It’s a stress relief for me. I really enjoy sharing this hobby with other students,” she said. “I would encourage people to consider exploring amateur radio because it’s a hobby that allows you to explore anything from technical electronics to international friendships. Amateur radio is open to anyone. It will help develop your professional and personal skills, participate in and learn from fascinating activities, and connect with an incredible community.” [ANS thanks Sarah Schuch and Kettering University for the above information] --------------------------------------------------------------------- AMSAT Argentina Balloon Flight Completes 2nd Trip Around the World AMSAT Argentina reports that their earth circling El PicoGlobo WSPR beacon balloon has now completed its 2nd lap around the world.

Work has been progressing on the FPGA or field programmable gate array which is at the heart of many modern software defined radios. Having powerful reconfigurable digital logic realizes a lot of the promise of SDRs. Balancing the workload between the general purpose processor and the FPGA is a big challenge. The RFNoC, or Radio Frequency Network on a Chip from Ettus Research for the 300 series USRPs before. RFNoC lets you place blocks that run on the FPGA in GNU Radio as if they were being run by the host computer. This lets you use the FPGA to full advantage within GNU Radio Companion. A comparison is made with the SDSoC, the Software Defined System on a Chip ,a tool from Xilinx. The team is looking for your help! If you can help ease the process of learning this environment, please let Michelle know: W5nyv(a)amsat.org [ANS thanks Michelle, W5NYV and the AMSAT Phase 4 Ground Station team for the above information] --------------------------------------------------------------------- AA5UK Announces March 1 Cayman Island Satellite Activation ZF2, CAYMAN ISLAND (Satellites, Grids, HF).

Voltera Circuit printer for prototyping is up and running the Hello World circuit. Video of this report at https://youtu.be/rdjKZCc9g74 There will be plenty more reports and feedback about the badge design over coming week as the JoCo Cruise embarks. Several of our team members are on the cruise and we can't wait to hear all about it. Everything that we've learned on this effort will be applied to the Hamvention badge, and to the Phase 4 Ground radios. We have some Software Defined System on a Chip progress. We have received our Xilinx specific JTAG Cable. Here it is! Charles Brain has been battling Petalinux and linux builds for his environment. Plenty of learning going on there. Some of us have received additional hardware from LimeSDR and there is more on the way. We have received very positive news from from Critical, the makers of Snickerdoodle, that official board definition files are in progress and will be available very soon. This means that those of us that are ordinary tool users, and not necessarily advanced tool makers, will be able to experiment and make progress with the Snickerdoodle, Xilinx Vivado, and the Xilinx SDK, more easily. SDSoC allows you to take functions written in C and C++, evaluate whether they would be better run on either the general purpose processor or the FPGA, and then assign them to the proper hardware. The 5GHz RF team is learning a lot about the impact of connectors on performance, and are evaluating some higher quality solutions. Several sets of team members are working on transverter designs. This is a very active and interesting area of investigation. There's a large number of tradeoffs and design patterns involved. We have a 10GHz specific effort, a high-performance multi band effort, the 5GHz RF team previously featured, and more. If you are interested in RF designs, then we are here to help. Ed Friesma at UNLV is taking on more of the correlator design. Our next report will be all about the progress on the DVB-S2 correlator, the GNU Radio block, what we can leverage from the GPU implementation, and next steps. On the 28th of February, we will have two guest speakers at our regular ASCENT conference call. Nate and Neal from Ettus Research will be addressing questions about the Careful COTS design of a USRP 300 series board for use in space. Having a powerful SDR at the heart of an amateur radio payload would put us in excellent position to deploy any modulation scheme we want. The Careful COTS version of a USRP is why Phase 4 Space was founded, and we've had a very good week in terms of outreach and evangelism. There's good news in an update to the Phase 4B mission on the Wide Field Of View satellite, with a launch scheduled for 2020. You can read about it in the article linked in the notes, from this past June. Our job on Phase 4 Ground is to make sure that you have a radio that can use this or any other payload that uses the Five and Dime air interface. And of course we want to fill up terrestrial microwave with the same fun and easy to use broadband digital microwave signals. If you're interested in learning more, then get in touch. http://www.losangeles.af.mil/…/final-rfp-released-for-laun…/ Plenty going on and lots of fun to be had. We will have a booth at Dayton as soon as possible, and we will be asking for time to talk at the Hamvention SDR forum about the Careful COTS effort, open source successes, and the impact of SDR advances on licensed and unlicensed services. After Hamvention is DEFCON. And we might have something up our sleeves this year. I'm working very hard on setting up a workshop and hackfest at GNU Radio Conference 2018, which will be held September 17-21 in Henderson, Nevada. This hackfest will focus on developing GNU Radio receiver blocks for DVB-S2 and S2X. If you are on the team or a supporter or find yourself interested in all of this, then please consider coming to the conference and participating in this effort. Tickets will be available very soon. It's a volunteer run event made possible by people just like you. And, there's an open space initiative from Lockheed Martin that we need to take a serious look at, and some new products on the market that might make our GSE and DVB-S2X manufactured solutions a bit easier. Howie DeFelice is on that trail and will report back. See you next week!
