idle comments
by Bob- W7LRD 18 Mar '18

18 Mar '18

Hello from Seattle I read the bb almost thoroughly throughout the day. A small common denominator is subtly appearing. I read, "I was on the bird all alone", or something like, "no one to talk to". The unusual conclusion, we have too many satellites! I never thought this ham would even think of it. If I look at Satpc32 with "only" a dozen listed, in fast forward a bewildering barrage of circles floats across the screen. I am not saying this is a bad thing, it just spreads us out and at times, there is, "no one to talk to". I do testing like try different power levels, talk to myself til as close to AOS as I can get. You know the drill. From what I read there are more on the starting block. I'd like to see more L band time, maybe a bird with a S band DL a MEO, a HEO- I know, idle comments. We have the five & dime coming at us, which sounds like a whole other world, I'm looking forward to it. Then there is the massive off air time making all this stuff work. Currently testing between two L band antennas and between two different 70cm antennas. At this time I have my Satpc32 talking fine with the radio but not with the rotor. A com port issue which currently I can not figure out. Assistance solicited. On the ISS it would be fun to see one of the "hams" up there have that "burning in the belly" to yuck it up, get WAS, VUCC, DXCC or whatever. Again, just idle comments not a criticism of the ARISS system. Sunny day in Seattle, xyl says yard work. 73 Bob W7LRD Seattle

March 15, 2018: The Amateur Radio on the International Space Station (ARISS) program is seeking proposals from US schools, museums, science centers and community youth organizations (working individually or together) to host radio contacts with an orbiting crew member aboard the International Space Station (ISS) between January 1 and June 30, 2019. Each year, ARISS provides tens of thousands of students with opportunities to learn about space technologies and communications through the exploration of Amateur Radio. The program provides learning opportunities by connecting students to astronauts aboard the International Space Station (ISS) through a partner- ship between NASA, the Radio Amateur Satellite Corporation, the American Radio Relay League, and other Amateur Radio organizations and worldwide space agencies. The program’s goal is to inspire students to pursue interests and careers in science, technology, engineering and mathematics (STEM) and Amateur Radio. A ham recently said, “ARISS shows how Amateur Radio is the most unique hobby/service there is.” Educators overwhelmingly report that student participation in the ARISS program stimulates interest in STEM subjects and in STEM careers. One educator wrote, “It exceeded our expectations--it created a great interest in both amateur radio and in space exploration. Our kids are completely inspired!” Ninety-two percent of educators who have participated in the program have indicated that ARISS provided ideas for encouraging student exploration and participation. An educator even joined the ham ranks, saying, “This chance for our school’s ARISS contact helped me see the great value of the ham world. I just passed my Technician License this weekend and have already signed up to take a General class.” ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed, exciting education plan. Students can learn about satellite communications, wireless technology, science research conducted on the ISS, radio science, and any related STEM subject. Students learn to use Amateur Radio to talk directly to an astronaut and ask their STEM-related questions. ARISS will help educational organizations locate Amateur Radio groups who can assist with equipment for this once-in-a-lifetime opportunity for students. The proposal deadline for 2019 contacts is April 30, 2018. Proposal webinars for guidance and getting questions answers will be offered March 29, 2018, at 7 p.m. EDT and April 16, 2018, at 4 p.m. EDT. Advance registration is necessary. To sign up, go to https://ariss-proposal-webinar-spring-2018.eventbrite.com For more details such as expectations, proposal guidelines and the proposal form, visit: http://www.ariss.org/hosting-an-ariss-contact-in-the-us.html About ARISS Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the Center for the Advancement of Science in space (CASIS) and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, tech- nology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or public forms. Before and during these radio contacts, students, educators, parents, and communities learn about space, space technologies, and amateur radio. For more information, see www.ariss.org.

Each year the American Radio Relay League (ARRL) sponsors Field Day as a “picnic, a campout, practice for emergencies, an informal contest and, most of all, FUN!” The event takes place during a 23-hour period on the fourth weekend of June. For 2018 the event takes place during a 27-hour period from 1800 UTC on Saturday, June 23, 2018 through 2100 UTC on Sunday, June 24, 2018. Those who set up prior to 1800 UTC on June 23 can operate only 24 hours. The Radio Amateur Satellite Corporation (AMSAT) promotes its own version of Field Day for operation via the amateur sat- ellites, held concurrently with the ARRL event. This year should be easier than many years since we have more than 10 transponders and repeaters available. Users should check the AMSAT status page at http://www.amsat.org/status/ and the pages at http://www.amsat.org/?page_id=177 for what is available in the weeks leading up to field day. To reduce the amount of time to research each satellite, see the current FM satellite table at http://www.amsat.org/?page_id=5012 and the current linear satellite table at http://www.amsat.org/?page_id=5033 If you are considering ONLY the FM voice satellites, there are SO-50, AO-85, AO-91, AO-92 and possibly PicSat. It might be easier this year to make that one FM contact for the ARRL bonus points with so many FM birds. The congestion on FM LEO satellites is always so intense that we must continue to limit their use to one-QSO-per-FM-satellite. This includes the International Space Station. You will be allowed one QSO if the ISS is operating Voice. The full set of rules are posted at: https://www.amsat.org/field-day/ [ANS thanks AMSAT Director Contests and Awards, Bruce Paige, KK5DO, for the above information] --------------------------------------------------------------------- HuskySat-1 Applies for IARU Coordination for Linear V/U Transponder The IARU Frequency Coordination pages show that the Husky Satellite Lab at the University of Washington applied for frequencies on March 7 for HuskySat-1, a 3U CubeSat with propulsion capability. Launch is planned for a high inclination LEO late 2018 on the ELaNA XXIV mission. HuskySat-1 will become the first amateur satellite from Washington state. HuskySat-1 will demonstrate the capabilities of new technologies being developed at the University of Washington and expand the capabilities of CubeSats as a whole. In particular, a high-thrust pulsed plasma thruster (PPT), and high-gain communications system will form the core technology suite on board the satellite. HuskySat-1 will carry AMSAT's 30 kHz wide V/u linear transponder for amateur radio SSB/CW communications. The transponder is the same design as the transponder being flown on RadFXSat-2/Fox-1E in 2018 including the 1k2 BPSK telemetry channel. HuskySat-1 will also transmit BPSK telemetry at 1 Mbps in the 24 GHz band. In order to utilize the transponder and telemetry beacon, equipment suitable for other linear transponder satellites such as FO-29 and AO-73 will be needed. Estimates are that a few watts into a small beam should be adequate, with a small beam with a low noise preamp serving for reception. Additional details have been posted at: https://sites.google.com/uw.edu/huskysatellitelab/huskysat-1 https://amsat-uk.org/2018/03/10/huskysat-1-cubesat/ IARU frequency coordination activities may be followed on-line at: http://amsat.org.uk/iaru/ [ANS thanks the IARU, the Unviversity of Washington, and AMSAT-UK for the above information] --------------------------------------------------------------------- Thousands of Kilometers Via Satellite and a WAS Award Too Listen to a recording of a 6005 KM contact with KE9AJ and OA4/XQ3SA on March 11: http://tinyurl.com/ANS-077-AO7-QSO Recording provided by NP4JV.

The ACMA recently approved the frequency allocation request and will be taking the application to the ITU on behalf of the project team. This is a huge achievement, particularly for an entirely student led organization. A major milestone has been passed with power-up test of everything to be included in the satellite all laid out on a flat surface called a FlatSat. The next step is to perform extensive software and hard- ware testing. The testing will be performed over the next few weeks. The Mission Operations website development is going well and the team is on track for launch at the end of this year / early next year.

Crabill, W3HQX Silent Key This week Larry Wright, W8ANT, reported the sad news that Perry F. Crabill, W3HQX, member of AMSAT, born in 1920, formerly of Washington, DC and suburban Maryland and until his passing of Winchester Virginia, is now a Silent Key at age 97. Perry was first licensed as W3HQX in "19ought38" as he was wont to say, worked for C&P telephone for many years, served in the US Navy in World War Two as a radio technician (passing the difficult Eddy test,) and was active for almost 70 years in a variety of amateur radio activities. Known affectionately by the 147.300 repeater's "Question Of the Day" group as "The Professor", Perry had a wide range of on-the-air acquaintances. A memorial service and celebration of his life was held on Saturday, March 24 in Winchester, VA. [ANS thanks Larry Wright, W8ANT for the above information] --------------------------------------------------------------------- China's DSLWP-A1/A2 Satellites to Transmit Amateur Radio Data from the Moon China is planning to launch the Chang’e 4 lander and rover which is slated to land on the far side of the moon in December. The lander configuration will use a relay satellite for a control and data link with Earth. Also aboard this flight will be a pair of microsatellites, DSLWP-A1 and DSLWP-A2, which will test low-frequency radio astronomy and space-based interferometry. These two lunar orbiting satellites developed by students at the Harbin Institute of Technology will include educational and amateur radio payloads (but not a trans- ponder). The Amateur Radio payload on DSLWP-A1 will provide a telecommand uplink and a telemetry and digital image downlink. Radio amateurs will be able to transmit commands that allow them to send commands to take and download an image. The IARU has coordinated downlinks on 435.425 MHz and 436.425 MHz for A1. Downlinks have been coordinated for A2 are 435.400 MHz and 436.400 MHz using 10K0F1DCN or 10K0F1DEN (10-kHz wide FM single-channel data) 250 bps GMSK with concatenated codes or JT65B. A1 and A2 will be deployed into a 200 × 9,000 kilometer lunar orbit. The 50 × 50 × 40 centimeter spacecrafts each weigh about 45 kilograms and are three-axis stabilized. Two linear polarization antennas are mounted along and normal to the flight direction. The satellites will use the moon to shield them from radio emissions from Earth for the long wavelength space-based interferometry experi- ments. The launch is anticipated for May or June on a CZ-4C vehicle, putting the satellites’ deployment about 6 months ahead of the launch of the Chang’e 4 lander and rover.

Unattended FoxTelem Question
by Roy Dean 17 Mar '18

17 Mar '18

Does FoxTelem automatically check for new Keps periodically, or only upon startup? I have an unattended station running on a Raspberry Pi, and I'm wondering if I shouldn't close and restart FoxTelem every couple of weeks to refresh TLE's. Scrolled through the command terminal and didn't see any updates occuring, but you can see keps being updated upon startup. -Roy K3RLD
