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).

Two microsatellites DSLWP-A1 and DSLWP-A2 carrying amateur radio payloads are planned to launch with the Chang’e 4 Relay satellite on a CZ-4C from the Xichang Space Center into lunar orbit in June 2018.

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.

Planning a launch into a 200 x 9000 km lunar orbit. Further info at https://web.archive.org/web/20170827105714/http://lilacsat.hit.edu.cn:80/

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

Es’hail-2 is expected to be positioned at 25.5 degrees East, as yet no launch date has been announced. Amateur transponder frequencies https://amsat-uk.org/satellites/geosynchronous/eshail-2/

On February 25, 2018 Es’hailSat @eshailsat tweeted that Es’hail-2 reached a major milestone in spacecraft and ground compatibility, with successful completion of TT&C RF and baseband compatibility tests https://twitter.com/eshailsat/status/967678982404689920

Radio amateur brings her hobby to university

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.”
