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



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

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 will use tungsten electrodes and a sulfur propellant.

HuskySat-1 will carry a 30 kHz wide 145 to 435 MHz linear transponder for amateur radio SSB/CW communications along with 1k2 BPSK telemetry. The satellite will also transmit BPSK telemetry at 1 Mbps in the 24 GHz band.

The launch is planned for late 2018 with the ELaNA XXIV mission into a high inclination Low Earth Orbit (LEO).

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.

Radio amateur brings her hobby to university

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.”

FM transponder satellite AO-92 open for amateur radio use

AO-92 / Fox-1D CubeSat

AO-92 / Fox-1D CubeSat

On the 03:25 UTC pass on January 26, 2018, AMSAT Vice President Engineering Jerry Buxton, N0JY, announced that AO-92 had been commissioned and formally turned the satellite over to AMSAT Operations. AMSAT Vice President – Operations Drew Glasbrenner, KO4MA, then declared that AO-92 was now open for amateur use.

Initially, the U/v FM transponder will be open continuously for a period of one week. After the first week, operations will be scheduled between the U/v FM transponder, L-Band Downshifter, Virginia Tech Camera, and the University of Iowa’s High Energy Radiation CubeSat Instrument (HERCI).

Schedule updates will appear in the AMSAT News Service Weekly Bulletins and will also be posted to the AMSAT-BB, AMSAT’s Twitter account (@AMSAT), the AMSAT North America Facebook group, and the AMSAT website at https://www.amsat.org/satellite-schedules/

AO-92 was launched on the PSLV-C40 mission from Satish Dhawan Space Centre in Sriharikota, India on January 12, 2018. For the past two weeks, the AMSAT Engineering and Operations teams have been testing the various modes and experiments on board. Testing has shown that both the U/v FM transponder and L-Band Downshifter work very well. The Virginia Tech camera has returned stunning photos and data from HERCI has been successfully downlinked.

AMSAT thanks the 178 stations worldwide that have used FoxTelem to collect telemetry and experiment data from AO-92 during the commissioning process. The collection of this data is crucial to the missions of AMSAT’s Fox-1 satellites. Please continue to collect data from AO-85, AO-91, and AO-92.

Radio Programming Chart – Fox-1D Doppler Shift Correction
Memory 1 (AOS) – TX 435.340 MHz (67.0 Hz Tone), RX 145.880 MHz
Memory 2 (Rise) – TX 435.345 MHz (67.0 Hz Tone), RX 145.880 MHz
Memory 3 (TCA) – TX 435.350 MHz (67.0 Hz Tone), RX 145.880 MHz
