ISS SSTV received by Edmund Spicer M0MNG

Radio amateurs around the world are receiving Slow Scan Television images on 145.800 MHz FM from the International Space Station.

The transmissions by ARISS Russia are in celebration of Cosmonautics Day and should continue until 1820 GMT on Saturday, April 14.

Pete M0PSX of Essex Ham reports receiving good pictures using a colinear antenna.

Edmund Spicer M0MNG, a regular guest on the bi-weekly ICQ Amateur Radio Podcast, received an image at 1730 GMT on Wednesday, April 11 using a 5 element ZL Special Yagi and a FT-991. He said it was probably the best quality image he’s ever received from the ISS.

Others have reported receiving images using just a $35 Baofeng UV-5R VHF/UHF FM handheld radio and 1/4 wave antenna.

We strongly encourage our girls to develop their interests both inside and outside the classroom. This culture of empowerment led one of our girls to apply to ARISS Europe (Amateur Radio on the International Space Station) for a highly prestigious link-up to the International Space Station.

This student-led initiative has resulted in a whole-school focus on Space Science, both in the classroom – from Engineering to English Literature – as well as co-curricular activities, including our ‘Mars Society.’

To support this programme, we have appointed our own Space Scientist in Residence – a unique position, we believe, for any school in the country.

Excitement is building for our live link-up to the International Space Station, when pupils from King’s High and Warwick Prep will talk with the astronauts on board.

King’s High And Beyond! – Adventures in Space

John McGuire, Space Scientist in Residence, has joined forces with Stratford Astronomical Society to organise a Stargazing Live event for students and parents of King’s High and Warwick Prep next Friday night. They will enjoy an Introduction to Astronomy, Telescope Talks, and ‘Ask an Astronomer’ sessions, before viewing the skies for themselves. This follows months of Space activity, from the very youngest pupils of Warwick Prep creating Mars models, to King’s students developing their own Amateur Radio Licensing Club, to set up a link between King’s and the International Space Station.

Live Link-Up to the International Space Station

Amateur Radio on the International Space Station (ARISS) logoWhen King’s High student, Eleanor Griffin was selected to hold a space conversation with an astronaut, she was inspired to set up the Warwick Mars Project, for students across the Warwick Independent Schools Foundation, to further interest in Space Science. Eleanor says: ‘The moon landings belong to the generation of our grandparents, and the International Space Station to our parents’. What will happen in our generation? Will Mankind travel to another planet?’ She will lead students in a live Q and A session with astronauts on the International Space Station on 19 April – the actual date depends on where the ISS is in orbit at the time.

From one girl’s interests and ambitions, a generation of King’s High and Warwick Prep pupils will benefit from an extraordinary range of opportunities and life-experience. We are also delighted that pupils from other local schools will be able to share in the excitement, by joining us for a ‘Space Day’ and the link-up itself. All power to our pupils!

The exciting journey pupils take at King’s High has expanded to a whole new dimension this academic year, as we explore the wonders of Space Science, with students from across the Warwick Independent Schools Foundation. At King’s, pupils have studied Space in lessons, from Engineering to English Literature, and developed a programme of student-led activities, including Space Blogs, an Astro-Photography competition, and a Space-themed dinner.

We recently appointed our own Space Scientist in Residence – a unique position, we believe, for any school in the country. Excitement is building for our live link-up to the International Space Station in April, when pupils from Warwick Prep and King’s High will talk with the astronauts on board.

There will be a live web stream from the event at https://live.ariss.org/

If you don’t have an amateur radio receiver you can still listen to the ISS by using an Online Radio, also known as a WebSDR. Select a Frequency of 145800.0 kHz and Mode FM:

ARISS Russia is planning a special Slow Scan Television (SSTV) event April 11-14 from the International Space Station in celebration of Cosmonautics Day.

The transmissions are to begin on April 11 at 11:30 UT and run through April 14 ending at 18:20 UT.

Supporting this event is a computer on the ISS Russian Segment, which stores images that are then transmitted to Earth using amateur radio, specifically the onboard Kenwood TM-D710E transceiver.

Transmitted images will be from the Interkosmos project period of the Soviet space program https://en.wikipedia.org/wiki/Interkosmos

The transmissions which were coordinated with the ARISS scheduling team, will be made on 145.800 MHz FM using the PD-120 SSTV mode.

Note the ISS transmissions use the 5 kHz deviation FM standard rather than the narrow 2.5 kHz used in Europe. If your transceiver has selectable FM filters try using the wider filter. Handheld transceivers generally have a single wide filter fitted as standard and you should get good results outdoors using just a 1/4 wave whip antenna.

The ISS Fan Club site will show you when the space station is in range http://www.issfanclub.com/

Jeri Ellsworth AI6TK will be AMSAT/TAPR Banquet Speaker during Hamvention

Jerri Ellsworth AI6TK

Jerri Ellsworth AI6TK

Entrepreneur and electrical engineer Jeri Ellsworth AI6TK will be guest speaker at the AMSAT/TAPR banquet which takes place during Hamvention 2018 in May.

The twelfth annual joint AMSAT/TAPR Banquet will be held on Friday, May 18 at the Kohler Presidential Banquet Center, 4572 Presidential Way, Kettering, OH 45429 (just south of Dayton). Doors open at 6:30 PM for a cash bar with the buffet dinner served at 7:00 PM.

Jeri Ellsworth, AI6TK, will present on her innovative ideas and adventures in Amateur Radio. Jeri is an American entrepreneur, self-taught engineer, and an autodidact computer chip designer and inventor.

She gained notoriety in 2004 for creating a complete Commodore 64 system on a chip housed within a joystick, called C64 Direct-to-TV. That “computer in a joystick” could run 30 video games from the
early 1980’s, and at peak, sold over 70,000 units in a single day via the QVC shopping channel.

Ellsworth co-founded CastAR (formerly Technical Illusions) in 2013 and stayed with the company until its closure on June 26, 2017. In 2016, she passed all three amateur radio exams, earned her Amateur Extra license, and received the AI6TK callsign. This has now launched new adventures into Amateur Radio. She has been featured in January 2017 QST and in YouTube videos from Quartzfest earlier this year. Jeri has been given a free hand to speak on whatever topic she wishes (as long as it’s amateur radio, somewhat).

End of mission for PicSat

Artist’s impression of PicSat in space

PicSat, launched January 12, carried an amateur radio FM transponder. Unfortunately following a loss of communications in March the team has had to announce the end of the mission.

On the afternoon of Tuesday, March 20, 2018 PicSat suddenly fell silent, after two successful morning passes over Europe. Attempts to re-establish contact have failed, nothing has been heard from the satellite, no sign of life.

There was a short-lived hope that PicSat was heard on Friday, March 30 by radio amateurs at the Morehead State University, but the faint signal heard turned out to be another satellite TIGRISAT.

On Thursday, April 5, 2018, the team decided to call mission-closed. A “pot” (French for party / drink) was organised at noon at the Paris Observatory in Meudon. Sylvestre Lacour gave a short speech. Four radio amateurs who have been PicSat fans and great supporters joined in via a dedicated Google Hangout.

The team will continue to try to understand what went awry, while plans for new projects are being made. PicSat was operational for over 10 weeks. From a technological point of view it has been a success for the LESIA laboratory of the Paris Observatory – PSL, for whom PicSat has been the very first nano-satellite complete built and operated in-house. This experience will open doors for new nano-satellite projects in the (near) future.

Watch Bye Bye PicSat (for now)

Wei Mingchuan BG2BHC reports DSLWP is a lunar formation flying mission for low frequency radio astronomy, amateur radio and education, consists of two microsatellites.

Developed by students at the Harbin Institute of Technology the amateur radio payload onboard DSLWP-A1 will provide telecommand uplink and telemetry / digital image downlink. An open telecommand is also designed to allow amateurs to send commands to take and download an image.

The satellites are 50x50x40 cm with a mass of about 45 kg and are 3-axis stabilized. Two linear polarization antennas are mounted along and normal to the flight direction.

The downlinks for DSLWP-A1 are 435.425 MHz and 436.425 MHz while downlinks for DSLWP-A2 are 435.400 MHz and 436.400 MHz using 10K0F1DCN or 10K0F1DEN. Will use 250/500 bps GMSK with turbo code or JT4G. Uplinks are reported to be in the 144 MHz band.

Nico PA0DLO says the two satellites, (also known as LongJiang 1 and 2) are planned to perform formation flying in a high elliptical orbit around the Moon (300 x 9000 km).

After launch it will take about 4 and a half days to reach the Moon. This GMAT script should work well for the first days after launch

The groundstation used in this script is a random location in New York City. You can change this to your location by updating the values under the GroundStation tab in GMAT.
