ISS SSTV image received by Mike Rupprecht DK3WN April 12, 2016 at 1556 UT

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/

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).

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 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/
