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.

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

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 team plans downlinks for A1 on 435.425 MHz and 436.425 MHz while downlinks for DSLWP-A2 would be 435.400 MHz and 436.400 MHz using 10K0F1DCN or 10K0F1DEN 250 bps GMSK with concatenated codes or JT65B.

Planning a launch into a 200 x 9000 km lunar orbit in June 2018. Further info at http://lilacsat.hit.edu.cn/

Athenoxat-1 QSL Card Challenge

Athenoxat-1 CubeSat 2015

Athenoxat-1

The Athenoxat-1 project team has implemented an interesting experiment (puzzle) where frames containing fragments of images of QSL cards are periodically transmitted by the satellite. Amateurs can participate in the experiment by receiving the fragments and sending KISS files via email to the Athenoxsat-1 project team. The frames will then be processed and the results will posted in their web site with acknowledgements to the participating stations.

AMSAT-BR would like to encourage amateurs to participate. Due to the satellite orbit inclination (15 degrees), only locations with latitudes below the tropics will be able to receive signals from the satellite. Signals can be demodulated using UZ7HO’s high speed soundmodem software (using the GOMX-1 4800 bps demodulator).

Original message from Yesie 9V1SQ describing the experiment follows:

Dear everyone,

Finally we’ve done with the preparation and in-orbit test of beacon puzzle round 2 (data type 3).
We can now inform you that Athenoxat-1 is beaconing data type 3 with 10 frames per burst every minute (30sec interval alternating with Morse CW).

For the stations around our control station (in Singapore), please keep tuning in as the satellite is still beaconing the data type 3 although it may seem appear busy in comm.operation.
The only apparent change is that you may not hear the Morse CW once our comm.operation starts.

We’ve updated our website here: http://www.micro-space.org/ham.html

We actually have started enabling this round 2 yesterday as part of in-orbit test to ensure the system is stable, before we can announce this officially.
At the same time, there are already kss files submissions, we’ll take them into account later.

Please let us know if you need any clarifications.
The kss files can be submitted through the usual address athenoxat@micro-space.org
Please feel free to inform others who may be interested and able to listen to Athenoxat-1.

Thank you in advance for listening.
73 de Athenoxat-1 team

The International Space Station (ISS) amateur radio Slow Scan Television (SSTV) transmissions on 145.800 MHz FM are expected to be activate over several days in April.

The Inter-MAI-75 SSTV experiment should be active on:
• Monday, April 2 from 15:05-18:30 UT
• Tuesday, April 3 from 14:15-18:40 UT

SSTV is also expected be active from April 11-14 world wide as part of Cosmonautics Day which takes place on April 12. Detailed times are still being worked into the schedule and will be published later. Images will be related to the Interkosmos project (https://en.wikipedia.org/wiki/Interkosmos).

The SSTV images will be transmitted on 145.800 MHz FM using the Kenwood TM-D710 transceiver located in the Russian ISS Service module. It is expected they will use the PD-120 SSTV format.

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.

HuskySat-1 145/435 MHz Linear Transponder CubeSat also has 24 GHz Downlink

HuskySat-1

HuskySat-1

A 3U Cube Satellite, dubbed the HuskySat-1, is being developed by an interdisciplinary team at the University of Washington and will be launched into Low Earth Orbit to become the first amateur satellite from Washington state

HuskySat-1 CubeSat

HuskySat-1 CubeSat

This CubeSat 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.

The majority of the HuskySat-1 is being developed at the University of Washington. The satellite is broken up into different subsystems. Each component is designed to be modular so that they can be most easily developed independently from each other and reused for future missions.

The Pulsed Plasma thruster uses tungsten electrodes and a sulfur propellant.

The DARC report the Es’hail-2 geostationary satellite, which will carry 2.4 to 10 GHz amateur radio transponders, was discussed at meeting in Doha in January.

A Google-English translation of the Deutscher Amateur Radio Club e.V. post reads:

Es'hail-2 Geostationary Satellite

Es’hail-2 Geostationary Satellite

At the invitation of Sabaan Mismar Al-Jassim, A71BP, General Secretary of QARS, Mustapha Landoulsi, DL1BDF, Coordinator of the Foreign Office for Arabic-speaking Countries, visited Doha in January to discuss topics of common interest with the Qatari radio-comrades and engage in radio-related activities QARS to participate. He was accompanied by Michael Regitz, DF4HR, and Prof. Dr. Wolfgang Borschel, DK2DO. The German OMs were u. a. by Abdullah bin Hamad al-Attiyah, former Deputy Prime Minister and Minister of Industry and Energy.

The focus of the talks was information about the new satellite Es’hail-2, which will be launched this year from the United States. Es’hail-2 is the first geostationary satellite with an amateur radio payload and a joint project by Qatar’s Qatar Amateur Radio Federation, Qatar Satellite Company and AMSAT-DL. With the stationing of the Phase 4 satellite, amateur radio traffic from Asia via Europe to South America will result in previously unknown opportunities for new activities.

Al Attiyah, who continues to play a key role in the international energy dialogue as president of a foundation for energy and sustainable development, has accepted an invitation from DARC e. V. and pay a visit to the HAM RADIO in Friedrichshafen. He will be there u.a. the amateur radio community are available for questions. The visit offers the opportunity to continue to promote the cooperation between the amateur radio associations of both countries and the concerns of international amateur radio. This is reported by Mustapha Landoulsi, DL1BDF, and Helmut van Edig, DL3KBQ.

Radio amateur brings her hobby to university

Ruth Willet KM4LAO

Ruth Willet KM4LAO

Kettering University reports student Ruth Willet KM4LAO brings her amateur radio expertise to campus.

Ruth, who is double majoring in Mechanical Engineering and Engineering Physics, was first licensed in June 2015. On her QRZ page she says:

“I love getting on the air on amateur radio satellites! I have operated from a number of grid squares in Georgia, Michigan, Virginia, and more. I am enjoying the challenge of balancing two radios and an arrow antenna, changing frequencies, and trying to talk on the satellite and remember callsigns at the same time! The more passes I do, the more I learn, and I am having a ton of fun. I started out on FM satellites only, and am slowly learning how to do linear satellites as well.”

The university article reports:

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.

“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.”
