EASAT-2 and HADES Updates
Felix Paez, EA4GQS, AMSAT-EA Mission Manager provided the last information on their satellites as of January 18, 2022.
"We confirm the reception of both EASAT-2 and HADES, as well as the decoding of telemetry and the FM recorded voice beacon with the callsign AM5SAT of the first one. EASAT-2 appears to be working well except for the deployment of the antennas, something that apparently has not yet occurred and causes weak signals. However, the AMSAT-EA team confirms that, based on the reception of FSK, CW, the FM voice beacon and the telemetry data that has been decoded, it can be said that the satellite is working perfectly. In the event of low battery or system malfunction, the on-board computer would not transmit CW messages or the voice beacon-callsign, as it would be in a 'safe' state with only fast and slow telemetry transmissions.
"These signals that have been able to confirm the operation of both satellites were received by Dr. Daniel Estévez EA4GPZ at 18:07 UTC on Saturday, January 15, using two antennas from the Allen Telescope Array. The TLEs used were obtained from the radio amateur community, with Doppler observations from the Delfi-PQ satellite, deployed together with EASAT-2 and Hades.
"TLEs used were these ones: https://github.com/AMSAT-EA/easat2-tle-lottery/blob/main/satnogs-2022-01-16-...
Daniel, EA4GPZ, performed a preliminary analysis using just one polarization of one of the satellite dishes. EASAT-2 has been detected with a relatively strong signal, close to the Delfi-PQ signal, obtaining said recorded voice FM beacon transmissions and FSK, FSK-CW at 50 baud.
"The CW beacon clearly shows the message: VVV AM5SAT SOL Y PLAYA, which is one of several that both satellites emit, although the callsign AM5SAT confirms that it is EASAT-2.
"In the recording made by Daniel EA4GPZ there is also a faint trace confirmed to be from Hades and stronger packets probably from the IRIS-A satellite.
"HADES, like EASAT-2, is transmitting weak signals, weaker than the ones of EASAT-2, most likely because the on-board computer has not yet managed to deploy the antennas either, although it will continue trying regularly. The reason the signals are suspected to be weaker at Hades is that the antennas are more tightly folded than those of EASAT-2. In any case, this is great news, since the transmission pattern confirms the proper functioning of the satellite. In the observations you can see the FSK tones with a deviation of about 5 kHz interspersed with the FM carrier corresponding to the voice beacon of the satellite, which has callsign AM6SAT. The AMSAT-EA team is working to try to decode the telemetry signals and obtain more detailed information on the state of the satellite.
"We kindly ask you, if you have very high gain antennas, to try to receive them, specially Hades. If we could decode telemetry it would be very helpful for us.
"Until antennas are deployed it will be very difficult to use their repeaters or to receive any SSTV camera images from Hades, but we hope that this will happen sooner or later, at least because even if the computer doesn't succeed applying heat to the resistor where the thread is attached, with time, the thread should break due to the space environment conditions.

AMSAT EA Receives Two OSCAR Designations: SO-114 & SO-115
On January 13, 2022, the EASAT-2 and HADES satellites were launched on a Falcon 9 launch vehicle from the Kennedy Space Center in Florida. Developed by AMSAT-EA, both satellites carry FM and digital repeater payloads to provide services to amateur radio enthusiasts around the world.
At the request of AMSAT-EA, AMSAT hereby designates EASAT-2 as Spain-OSCAR 114 (SO-114) and HADES as Spain-OSCAR 115 (SO-115). We congratulate AMSAT-EA, thank them for their contribution to the amateur satellite community, and wish them continued success on this and future projects.

Amateur Operation in 3.45 – 3.5 GHz Must Cease by April 14, 2022
The FCC has established April 14, 2022, as the date by which amateur radio transmissions must stop in the upper 3.45 – 3.5 GHz segment of the amateur secondary 9-centimeter band. Secondary operations are permitted to continue indefinitely in the remainder of the band, 3.3 – 3.45 GHz, pending future FCC proceedings.
On January 14 the FCC released DA 22-39, which announces the results of Auction 110 for the 3.45 – 3.55 GHz band. Release of this notice triggered FCC rules adopted last year requiring that amateur radio operations between 3.45 GHz and 3.5 GHz cease within 90 days of the public notice.
In October 2021, ARRL President Rick Roderick, K5UR, urged Congress to direct the FCC to preserve Amateur Radio’s secondary use of the 3 GHz band in a written statement responding to H.R. 5378, the Spectrum Innovation Act of 2021, before the US House Commerce Communications and Technology Subcommittee.
A chronology of actions responding to amateur access on the 3.5 GHz band can be found on the ARRL website.

Launch of a Wooden Satellite Still Pending
Two spacecraft comprised of wood or using wooden framing are hoping to launch this year and next. One will carry an amateur radio payload.
WISA Woodsat, a Finnish spacecraft that planned to include an amateur radio payload, was forced to postpone its announced launch target from 2021 to 2022 after the International Amateur Radio Union (IARU) Amateur Satellite Frequency Coordination system turned away its request to use amateur radio frequencies.
“I regret to inform you that IARU is not in a position to support the WISA Woodsat Coordination request,” the coordinator said. “The main reason is that the primary mission doesn’t seem to be an amateur mission.”
As announced last year, WISA Woodsat was designed to accommodate multiple missions — from materials science, space education, and awareness to promoting and facilitating amateur radio communication with and via satellites. No transponder was on board, but the satellite’s sponsors said they had the support of Finland’s IARU member-society, SRAL, to use amateur radio frequencies. They are now reworking the spacecraft to use commercial radio frequencies.
“To our great disappointment, we can’t serve the radio amateur community with the LoRa-repeater mission as we had hoped and planned. We will continue to share the pictures and data online, but the technical aspect has been diminished due to this decision,” said WISA Woodsat’s Chief Engineer Samuli Nyman of Arctic Astronautics.
Meanwhile, LignoSat, a 1U-sized CubeSat with an outside structure mainly composed of wood, has applied for IARU frequency coordination and hopes to launch from the ISS in 2023. Built by students at Japan’s Kyoto University, LignoSat includes a unique amateur radio payload but not a transponder.
The LignoSat application for IARU Satellite Frequency Coordination in December said the CubeSat would carry amateur radio equipment that will extract call signs of amateur radio stations from uplinked FM packet signals and respond to them via the CW downlink and the sender’s call signs to convey thank you messages. The plan proposes UHF downlinks for CW and FM.
The satellite’s development team, comprised of Kyoto University and Sumitomo Forestry Company, said it’s aiming to harness the environmental friendliness and the economy of wood in spacecraft development. They say a satellite with a wooden exterior would burn up upon re-entering Earth’s atmosphere at the end of its mission, lessening its burden on the environment. The wooden framework also will permit the satellite’s antennas to be inside the spacecraft. A plan is under way to use an experimental apparatus on the International Space Station to hold wooden sheets of varying hardness, taken from several tree species, attached. These would remain exposed to the space environment for about 9 months to determine their deterioration.
The team is headed by Japan Aerospace Exploration Agency (JAXA) astronaut Tako Doi. Now a Kyoto University professor, Doi was the first JAXA astronaut to take part in spacewalks from the shuttle Columbia in 1997. He said the concept, if successful, could lead the way to “allowing even children who are interested in space to make a satellite.” LignoSat would be deployed from the ISS in July 2023.

Satellite Shorts From All Over
+ The January operating schedule shows one remaining date in January for FO-29 operation. That will be January 29 from 00:03 UTC until battery exhaustion. FO-29 will be in full sunshine from January 28 to the end of April. During that time, continuous operation can be expected. [AMSAT thanks Akira Kaneko,JA1OGZ, for the above information.]
+ The SpaceX Smallsat Rideshare program offers a viable and affordable option to launch up to 200 kg into a sun-synchronous, low Earth orbit. That is why, along with approximately 80-90 other satellites, USC’s Dodona satellite—it’s third ever—hitched a ride on SpaceX’s latest mission, Transporter 3 this week. Dodona is a project out of USC’s Space Engineering Research Center. Part of SERC’s mission is creating hands-on opportunities for students and faculty to build and test advanced space technology, in addition to integrating, launching and operating small satellites. Dodona takes advantage of the space focused curriculum through analysis tools and techniques that are taught at USC through the Astronautical Engineering Department. The complete story can be found at https://www.isi.edu/news/45250/usc-launches-its-3rd-satellite-into-space/. [AMSAT thanks Information Sciences Institute for the above information.]
+ The very first Svalbard QO-100 Satellite DX-Pedition will take place April 22-24, 2022 from Kapp Linné – Isfjord Radio at 78° North. They will operate two QO-100 satellite stations under the callsigns JW0W and JW100QO, while JW0X will be used by another team for contacts on shortwave. With QO-100 only 3° above the horizon, Kap Linné was the only suitable place in the area with Svalbard at the edge of the satellite footprint. Looking for a suitable location to stay and getting there, is one of the biggest challenges and cost drivers for the team. More information at https://amsat-dl.org/en/svalbard-qo-100-satellite-dx-pedition/. [AMSAT thanks AMSAT-DL for the above information.]
+ The University of Cambridge has announced the creation of the Raspberry Pi Computing Education Research Centre.
