Das DARC-Remoteprojekt ist gestartet Auf der HAM RADIO wurde das DARC-Remotestationsprojekt feierlich gestartet. Es war Ende des Jahres 2023, als der DARC-Vorstand dazu aufrief, sich mit einem Standort fuer eine Remotestation fuer das bis dato aufzubauende Stationsnetzwerk zu bewerben. 18 Gruppen hatten sich daraufhin gemeldet, schlussendlich wurden 15 ausgesucht. Auf der Messe fiel nun der Startschuss, sodass alle DARC-Mitglieder das neue Serviceangebot des DARC e.V. nutzen koennen. Es muss eine Clientsoftware heruntergeladen werden, der Funkbetrieb erfolgt daraufhin ueber das Internet - ohne eigene Antenne. Eine entsprechende stabile Internetverbindung natuerlich vorausgesetzt. Finanziell wurde das Netzwerk durch die DARC-Mitgliedschaft Pro ermoeglicht. Rein rechtlich fiel der Startschuss allerdings schon ein Jahr vorher mit dem Inkrafttreten der novellierten Amateurfunkverordnung (AFuV), die nun Remotebetrieb ermoeglicht. Die Software wurde von Roland Wolf, DL1EHP, programmiert, der auf der Aktionsbuehne nach dem kollektiven Startschuss der Stationsbetreiber die Software in Aktion erklaerte und ein Demo-QSO vorfuehrte. Ernst Steinhauser, DL3GBE, betreute das Projekt seitens des Vorstandes und zeigte noch eine Karte, wie sich die Stationen ueber Deutschland verteilen. Leider ist der Norden Deutschlands noch nicht “abgedeckt”, hier waeren noch vielleicht drei weitere Standorte willkommen, so DL3GBE. Wie kann man nun die Remotestationen nutzen? Dazu klickt man auf die entsprechende Kachel unter MyDARC [1]. In der Clientsoftware ist zu beachten, dass immer ein Nutzer Operator ist, also VFO verstellen und senden kann. Alle anderen Nutzer sind SWLs. Ein ausfuehrliches Erklaervideo hat Michael, DL2YMR, auf seinem YouTube-Kanal veroeffentlicht [2]. Das Nachrichtenportal Heise hat dem Remoteprojekt ebenfalls einen Beitrag gewidmet, leider befindet sich der Artikel hinter einer Bezahlschranke [3].
13-Jaehriger stellt neue Bestmarke in Hochgeschwindigkeits-Telegrafie auf 1160 Zeichen pro Minute: Der 13-jaehrige Rumaene Alexandru Ianis Scutaru, YO8YNS, hat am Samstagvormittag auf der HAM RADIO-Aktionsbuehne die Zuschauer ins Staunen versetzt. Als mehrfacher Weltmeister in der Hochgeschwindigkeits-Telegrafie unternahm er live einen Rekordversuch in RufzXP. Trotz seines jungen Alters ist Ianis Alexandru Scutaru schon ein alter Hase in der High-Speed-Telegrafie: Bereits bei der Schnelltelegrafie-Weltmeisterschaft in Tunesien im vergangenen Jahr hatte YO8YNS mit einer Punktzahl von 311.192 Punkten und einer Hoechstgeschwindigkeit von 1126 Zeichen pro Minute einen neuen Weltrekord aufgestellt, den er nun weiter verbessern konnte.
Neue Kooperationen auf der HAM RADIO geschlossen Der armenische Amateurfunkverband FRRA laesst ab sofort seine auslaendischen QSL-Karten ueber das Buero versenden. Auf der HAM RADIO wurde ein entsprechender Vertrag unterzeichnet. Die aus Armenien zu versendenden QSL-Karten werden, nach Laendern vorsortiert, an die DARC-Geschaeftsstelle in Baunatal versendet, wo sie den Auslandskarten der deutschen Funkamateure beigefuegt werden. Arman Babloyan, EK6NK, Praesident der Federation of Radiosport of the Republic of Armenia (FRRA), zeigte sich bei der Vertragsunterzeichnung auf offener Buehne sehr zufrieden mit der Vereinbarung. Kooperationsvertraege fuer den QSL-Servi ce gibt es bereits mit den Amateurfunkverbaenden von oesterreich, Schweiz, Daenemark, Israel, Schweden und Nordmazedonien. Zwei Vereine mit demselben Ziel - unter diesem Motto sind der Verein Notfunk Deutschland e.V. und der DARC e.V. eine weitreichend e Kooperation eingegangen. Auf der HAM RADIO wurde besiegelt, was ein Jahr zuvor am selben Ort als Idee entstand. “Wir wollen unsere Kompetenz buendeln, um das so wichtige Thema Notfunk erfolgreicher angehen zu koennen”, beschreibt Oliver Schlag, DARC-Referent fuer Not- und Katastrophenfunk, die Motivation beider Vereine. Ruediger Stingel, Vorsitzender von Notfunk Deutschland, ergaenzt: “Nothilfe jedweder Art sollte kein Thema sein, bei dem es um Konkurrenz geht.” Neben dem Austausch von Wissen und Kontakten stehen die Ausbildung der Vereinsmitglieder und die Fortbildung im Vordergrund der Zusammenarbeit. Auch eine Kraeftebuendelung bei gemeinsamen uebungen sowie die Werbung fuer das wichtige Thema Notfunk umfasst die Kooperation.

Der Funkwetterbericht vom 2. Juli, erstellt von Hartmut Buettig, DL1VDL Zunaechst der Rueckblick vom 23. Juni bis 2. Juli: Obwohl 10 Sonnenfleckenregionen etwa gleich verteilt auf beiden Hemisphaeren der Sonne sichtbar sind, war die Sonnenaktivitaet gering und nur von C-Flares gepraegt. Der solare Fluxindex stieg leicht von 120 auf 128 Einheiten. Das geomagnetische Feld war bis zum Abend des 25. Juni ruhig, dann bis zum 27. Juni mittags stark gestoert und danach wieder ruhig. Die Geschwindigkeit des Sonnenwindes erreichte am 26. Juni 888 Kilometer pro Sekunde [4]. OK1HH schrieb im ARRL-Funkwetterbericht, dass die gestiegene Konzentration von freien Elektronen in der Ionosphaere leider ein bekanntes Phaenomen in diesem Jahr ist, das die Kurzwellenausbr eitung negativ beeintraechtigt [5]. Die hohe ionosphaerische Daempfung spuerten wir taeglich. Die besten DX-Bedingungen fanden wir morgens und abends auf 20 m. Tagsueber wurden wir mit Short-Skip-Bedingungen durch die sporadische E-Schicht belohnt. Die fuer 3000 km Sprungentfernung geltende MuF2 betrug nachts etwa 14,5 MHz. Sie lag zum lokalen Sonnenaufgang bei 13 MHz, stieg mittags auf etwa 18 MHz und kulminierte zum Sonnenuntergang bei 19 MHz. Zwei Stunden spaeter betrug sie noch 17 MHz. Der Referenztag fuer die Station Juliusruh war der 29. Juni [6].
Vorhersage bis 9. Juli: Am 5. und 12. Juli erwarten wir die Wiederkehr der aktiv gewesenen Regionen 4114 und 4117. Damit steigt unsere Hoffnung nach etwas besseren Ausbreitungsbedingungen. Die Aktivitaet des Erdmagnetfeldes bleibt wegen koronaler Effekte und Sonnenwind unbestimmt bis aktiv. Positiver Faktor im Funkwettergeschehen bleibt die sporadische E-Schicht, die sowohl die oberen Kurzwellenba ender als auch das 6-m-Band positiv beeinflusst. Waehrend die globale Erwaermung indirekt Auswirkungen auf die Ionosphaere haben kann, das wird gegenwaertig erforscht, ist eine direkte Korrelation zwischen Erwaermung und Ionosphaerendaempfung derzeit nicht eindeutig belegt [7].
Es folgen nun die Orientierungszeiten fuer Gray-Line DX, jeweils in UTC:
Sonnenaufgang: Auckland/Neuseeland 19:34; Melbourne/Ostaustralien 21:36; Perth/Westaustralien 23:17; Singapur/Republik Singapur 23:02; Anchorage/Alaska 12:24; Johannesburg/Suedafrika 04:55; Tokio/Japan 19:28; Honolulu/Hawaii 15:52; San Francisco/Ka lifornien 12:51; Port Stanley/Falklandinseln 12:05; Berlin/Deutschland 02:47.

AMSAT-EA
HADES-ICM becomes SO-125
The HADES-ICM satellite of the Spanish AMSAT-EA, a 1.5U PocketQube, is now a member of the OSCAR fleet. Upon request, the satellite was designated SO-125. It carries an SDR-based FM and digital repeater payload for amateur radio.
HADES-ICM was launched on March 14, 2025, aboard a Falcon 9 rocket as part of SpaceX’s Transporter 13 mission from Vandenberg Space Force Base, California. The satellite entered service on March 31. The FM repeater is expected to be activated in June initially on weekends, with plans for a later transition to full-time operation.
HADES-ICM also hosts an experimental payload from the Smart IR/Graphene Engineering Innovation Centre (GEIC) at the University of Manchester. Data from this experiment will be publicly broadcast via telemetry packets.
The satellite carries an FM and digital repeater payload built on an enhanced SDR-based platform, capable of transmitting up to 0.25 W when battery conditions permit. This makes it accessible to stations with handheld antennas such as the Arrow antenna. The coordinated uplink frequency is 145.875 MHz, and the downlink frequency is 436.666 MHz. The repeater operates with an open squelch and does not require a subtone. The satellite has been cataloged with the NORAD number 63492.

Lecture “Amateur radio meets space travel”
Lecture DK5LA
Radio amateurs continue to be involved in research and development: A few years ago, the Chinese launched satellites to the moon in order to be able to conduct research in space. Since radio traffic data is only possible with a clear line of sight between the stations involved, the Chinese team could only send or receive data when the moon is in their sky. A station here in Europe was therefore required. Reinhard, DK5LA, near Flensburg was able to take on the task in the 2 m band and send data to the satellite.
He also managed to establish the first connection via a satellite in lunar orbit. This was a new milestone in radio history. He will give his lecture “Amateur radio meets space travel” on March 6th in the planetarium in Glcksburg. Information a"out the event and registration can be found at www.planetarium-gluecksburg.de/…/2025-03-0 6-19-00.html. Ulrich Fenner, DL2EP, reports on it.

“Hacker” makes abandoned BEESAT-1 functional again
In 2009, BEESAT-1 was launched into low Earth orbit as the first 1U CubeSat from the Technical University of Berlin. In 2013, operation s were largely discontinued, apart from occasional checks every few years to determine whether the satellite was still responding to commands. Now a “hacker” has repaired the satellite, which is now usable again for radio amateurs.
In 2024, PistonMiner, the hacker’s pseudonym, repaired a number of software problems on BeeSat-1, restored the telemetry function and downloaded images from the camera for the first time. His work was presented at the 38th Chaos Communication Congress from December 27th to 30th, 2024 in Hamburg.
Restoring BEESAT-1’s operational readiness was particularly attractive because, according to current estimates, it will remain in space for at least another 20 years due to its higher orbit of over 700 km. In addition, the satellite is equipped with a number of sensors and actuators that were not fully used during the main mission and could be used in an extended mission.

Launch of HADES-R and HADES-ICM planned for the first quarter of 2025
After HADES-D (SO-121), AMSAT-EA will provide radio amateurs with two new satellites, HADES-R and HADES-ICM, at the beginning of 2025. These are intended to replace SO-121, which burned up in the Earth’s atmosphere at the beginning of November, in orbit. Both satellites in the PocketQube 1.5P format (5 5 7.5 cm) will be launched by SpaceX as part of the Transporter-12 and Transporter-13 missions.
The AMSAT-EA satellites are developed and built with technical support from private companies and universities. The transmission power will vary depending on the battery level between 40 mW and theoretically 250 mW when fully charged.
The uplink is in the VHF band and the downlink is in the UHF band, they also transmit telemetry with their status as well as voice and CW messages.

Japan launches the first “wooden satellite” with amateur radio payload
Japanese researchers have launched the world’s first wooden satellite, LignoSat, into space, taking a step toward exploring the suitability of wood for lunar and Martian construction. Developed in collaboration between Kyoto University and Sumitomo Forestry, the satellite was launched on board a SpaceX mission to the International Space Station on November 4, 2024. From there, LignoSat is scheduled to be deployed into an orbit at an altitude of about 400 kilometers.
LignoSat, a 1U CubeSat, carries an amateur radio payload. A downlink on 435.820 MHz has been coordinated for CW, 4k8 GMSK AX25 telemetry, and FM. For more information, visit …innovationkyoto.org/amateur-radio-operators/
The satellite, whose name is derived from the Latin word for “wood,” is a compact, palm-sized structure. LignoSat is designed to demonstrate the potential of wood as a sustainable and durable material for space exploration. Takao Doi, a former astronaut and current researcher at Kyoto University, explained that the use of wood could pave the way for building habitats that enable human life and work in space.
One of LignoSat’s main tasks during its six-month orbit will be to measure wood’s resilience to extreme space temperatures, which fluctuate between -100 and 100 C every 45 minutes as the satellite moves from sunlight to darkness. The sensors on board the satellite will also monitor how well the wood mitigates the effects of space radiation on semiconductors.
The team behind LignoSat is optimistic that their experiment could inspire a wider application of wood in space exploration. Doi even hinted at the potential for future partnerships: “If we can prove that our first wooden satellite works, we want to offer it to Elon Musk’s SpaceX.”

Editorial 11/06/2024 AMSAT
AO-7 celebrates 50th anniversary
It is often reported that the oldest satellites still functioning in space are the Voyager 1 and Voyager 2 spacecraft. These probes were launched in 1977, but are they really the oldest functioning spacecraft in space? If we also take into account the satellites in Earth orbit, the oldest functioning satellite that continues to be available to radio amateurs around the world is AMSAT-OSCAR 7 (AO-7), launched on November 15, 1974.
In its first phase of operation, AO-7 had a lifespan of 6.5 years. In late 1980, AO-7’s NiCd batteries began to show signs of increased resistance. This was a sure sign to the AMSAT command stations that the end was in sight. The cells had originally been tuned by NASA for their capacity. In fact, they failed in June 1981, when a three-week period began in which the satellite spent 20 minutes in the Earth’s shadow.
AO-7 remained inactive for almost 21 years. However, in the summer of 2002, AO-7 came back to life. Probably due to radiation, the status of a NiCd battery changed so that the solar cells could once again supply power to the control and communication units.
Pat Gowain, G3IOR, was the first to discover the CW telemetry of the satellite, which was thought to be silent, on June 21, 2002 and informed Perry Klein, W3PK, the first AMSAT president and designer of the VHF/HF transponder. As a result, many satellite enthusiast s began to observe the signals from AO-7, and the second life of the “Sleeping Beauty” satellite began.
AMSAT has provided a detailed article on AO-7 on its website: amsat.org/amsat-ao-7-a-fifty-year-anniversary/. The AMSAT News Service reports on this

IARU processes the 1000th request for an amateur satellite frequency
IARU
The International Amateur Radio Union (IARU) recently processed the 1000th request for coordination for an amateur satellite frequency. The IARU Satellite Frequency Coordination Panel has faced new challenges in recent years with the increasing popularity and growth of cube satellites.
Given the lower cost of launching these small satellites, the focus is on carefully managing the radio frequency spectrum and ensuring minimal interference with terrestrial services. “As Earth’s orbit becomes increasingly crowded, the IARU’s work in the area of ??frequency coordination will also be critical for future missions,” explains the IARU.

AMSAT-EA plans HADES-R and HADES-ICM for 2025
The Spanish AMSAT has announced the upcoming launch of two new satellites, HADES-R and HADES-ICM. They are expected to be available to radio amateurs at the beginning of 2025. These satellites are intended to replace the current HADES-D (SO-121) satellite in orbit. Unlike HADES-D, which transmits with a transmission power of 40 mW, the new satellites will have a variable transmission power that can theoretically be up to 250 mW when the batteries are fully charged. The HADES-R and HADES-ICM satellites, in the format of a 1.5 pocket qube, will be launched by SpaceX with the Transporter-12 and Transporter-13 missions. The launches will use D-Orbit’s ION Orbital Transfer Vehicle, or OTV, with mission management provided by Alba Orbital, a Scottish company specialising in satellite launch solutions. As with previous AMSAT-EA projects, these satellites were developed with support from private companies and universities.
Both satellites will support a wide range of communications functions, including FM voice, FSK, FT4 and FT8 modes. They will also be equipped for AX.25/APRS communications at 300 and 1200 bps. The satellites will uplink in the VHF band, while the downlink will operate in the UHF band. In addition, the satellites will transmit telemetry data, including status updates, voice messages and CW messages. All communications will be handled via an SDR-based FM and FSK repeater, which is available at all times and activated by squelch without the need for subtones, for example. In addition to their primary communications functions, both satellites will carry a scientific experiment from the Smart IR/Graphene Engineering Innovation Centre, or GEIC, at the University of Manchester. HADES-ICM is sponsored by Florida-based IcMercury (Interstellar Communication Holdings) and will carry several messages embedded in the FSK telemetry. While the frequency range of the HADES-R satellite has already been coordinated by the IARU, approval for HADES-ICM is still pending. The AMSAT News Service reports this with reference to Flix Pez, EA4GQS, President/Mission Manager.

ERMINAZ mission postponed to 2025
As AMSAT-Deutschland e.V. reports on its website, on August 19, 2024, just a few weeks before the planned launch date of the ERMINAZ payload, an incident occurred during a test of the RFA One rocket from Rocket Factory Augsburg (RFA) that led to the complete loss of the first rocket stage. As a result, the ERMINAZ mission has to be postponed until next year, but the exact launch date is still open.
The UNNE-1, MARIA-G, SIDLOC-PQ-1, SIDLOC-PQ-1, QUBIK-5, and ERMINAZ-1U and ERMINAZ-1V satellites are part of the Erminaz mission, a joint effort between AMSAT-DL, AMSAT-EA, and the Libre Space Foundation, with each organization flying its own satellites and using the PicoBus deployer developed by Libre Space in the ERMINAZ mission.
ERMINAZ-1U and ERMINAZ-1V are AMSAT-DL’s two PocketQubes. They are intended to carry out a series of telecommunications experiments in the amateur radio field, using various modulation, coding, and framing schemes. In addition to a CW beacon, SSDV is also planned for digital image transmission, the images of which are stored on a micro SD card and transmitted cyclically. The aim here is to gain long-term experience under space conditions with SD cards. In addition to telemetry in the CCSDS standard, a CCSDS digipeater is also implemented, so radio amateurs can also communicate directly via the two ERMINAZ PocketQubes, although it is not AX.25 compatible. A sensor board is also on board to measure beta, gamma and X-ray radiation in orbit.
Another goal of ERMINAZ-1U and -1V is to introduce and involve students from Bochum University of Applied Sciences in the space projects of AMSAT-DL, in cooperation with the Bochum Observatory.

NASA discovers spectral formations in LEO orbit
NASA scientists have discovered unusual formations in Earth’s ionosphere. The ionosphere extends from 80 to 1000 km above the Earth and forms the boundary between our planet’s atmosphere and space. Although it is home to most of the satellites orbiting the Earth, it is vulnerable to electromagnetic storms emanating from the sun.
Under certain conditions, the layer can become electrically charged. As the GOLD (Global-scale Observations of the Limb and Disk) observation satellite found, plasma bands extending across the ionosphere can lead to unusual X and C formations. It is a startling “alphabet soup,” as NASA called the findings in a press release. This could shed light on how space weather can affect our planet’s upper atmosphere and “disrupt radio and GPS signals.”
Charged particles formed dense bands or “ridges” around Earth’s magnetic equator, while elsewhere areas of low density caused by the setting sun took shape, NASA said. Scientists believe major disturbances such as solar storms or massive volcanic eruptions cause multiple ridges to join together to form an X-shape, as previous GOLD observations have shown.
But now scientists have discovered the same shapes without such a cause, during a quiet period of solar activity. “It’s an unexpected feature during geomagnetically quiet conditions,” Fazlul Laskar, a research associate at the University of Colorado and lead author of a paper on the discovery earlier this year, explained in a NASA statement.
In addition to an “X,” some formations in the ionosphere also take on the shape of a “C,” which new observations show can occur in close proximity to each other. “The fact that we have bubbles so close together with very different shapes tells us that the dynamics of the atmosphere are more complex than we expected,” said NASA scientist and ionosphere expert Jeffrey Klenzing.

AMSAT-DL publishes geostationary satellite proposal
In response to the IARU and ESA’s request for feedback from the amateur radio community regarding a geostationary satellite, AMSAT-DL has published a comprehensive proposal for a geostationary microwave amateur radio payload [1]. The 31-page document proposes a satellite position at 43 West that would include Central, Southern and Eastern European countries, parts of Scandinavia, Africa as well as large parts of the North American continent, Central and South America.
Other considerations include hosted and unhosted payloads, a micro-GEO platform, and future European launch systems as a method of transport to orbit. The proposal goes into great detail about possible frequency bands, transponders, link budgets and even draft frequency plans.

Editorial February 20, 2024 Software AirScout Web
“AirScout Web” presented
At the recent GHz conference over the weekend, Frank Schmhling, DL2ALF, presented the new web version of the AirScout software: web.airscout.eu. AirScout itself has been around for several years (www.airscout.eu) and is an essential software tool for predicting aircraft scatter, i.e. signal reflections in the VHF range on aircraft. While AirScout was primarily written as Windows software and can be installed on a PC, the new web version is platform-independent and runs in a web browser.
AirScout Web also works on smartphones and tablet computers. If you want to use the new system, you first create an account. The user interface is similar in many parts to the installation variant. But there are also functions that differ depending on the system. A few features are currently not implemented, such as CAT control, wtKST coupling or alarm function. The presentation from the GHz conference AirScout goes Web can be downloaded from the DLGTH website: dl0gth.dl2alf.de/index.php/docu. If you would like to delve deeper into how AirScout works in general, you should also watch the lecture AirScout Deep Dive for Advanced Users on the same page.

SLIM mission: An amateur radio beacon on the moon
As part of the SLIM mission of the Japanese space agency JAXA, there is currently an amateur radio transmitter on the moon. Shortly before the probe landed, the LEV-1 and LEV-2 payloads were deployed. The collected data from LEV-2 is received by LEV-1 and transmitted as a beacon on 437.41 MHz at 1 W. LEV-1 operates under the call sign JS1YMG [1]. However, the mission struggles with technical problems, but is still considered a success by JAXA [2].
SLIM (Smart Lander for Investigating Moon) was launched on September 6, 2023 together with the XRISM X-ray telescope. The mission goal of the 700 kg probe is to land safely and precisely on the moon. Navigation is based on camera images and the landing site should be hit with an accuracy of 100 m. On January 19th at 12:20 a.m. Japanese time, SLIM touched down - albeit incorrectly, which caused problems with the power supply due to the compromised solar cells. SLIM was therefore switched off several times to save electricity [3]. SLIM carries several payloads, including LEV-1 and LEV-2/Sora-Q. Lunar Excursion Vehicle 1 (LEV-1) is a jumping lunar rover. He should take measurements immediately after landing. LEV-2, meanwhile, is designed as a spherical, two-wheeled lunar rover with a diameter of 8 cm. Sora-Q has two cameras and should take images for about two hours after landing. Daniel Estevez, EA4GP, presents the method and extraction results for the demodulation of the Morse code from the signal transmitted by ‘LEV-1’ and the extraction of the code string (call sign and HK data in hexadecimal form), it says [4]. Unfortunately, due to the low energy budget, the transmitter has only been active for a short time [5]. In contrast to EME operation (Earth-Moon-Earth), which is based on signal reflections on the lunar surface and has a path loss of 240…290 dB depending on the frequency, this is an active transmitter on the lunar surface itself. However, it is also Antenna effort is required here to receive the signals, which are only 1000 mW strong. SLIM is currently retired. The command team waits for sufficient sunlight to fall on the solar cells. This is expected to happen on February 15th. It remains to be seen whether SLIM will report back because the probe is not designed for the cold nights on the moon.

QO-100 High Speed Multi Media Beacon
The new AMSAT-DL Highspeed Multimedia Modem developed by Kurt DJ0ABR for the QO-100 NB transponder allows a transmission speed of up to 7200 bit/s in 8 APSK or 4800 bit/s in QPSK despite the maximum allowed bandwidth of 2.7 kHz.
It is thus significantly more efficient than conventional methods on the QO-100 transponder and it can be used to transmit any data and voice in full duplex. The software is open source and available free of charge.
Since the end of May 2022, the MM beacon from the QO-100 ground station (DK0SB) in Bochum is active. Settings:
Center frequency: 10,489,995 MHz Zero beat, ssB: 10,489,993.3 MHz Modulation: 8 APSK Symbol rate: 7200 bit/s HF bandwidth: 2700 Hz

Wow. Just, WOW
Imagine having this on other (I assume) LEO satellites as a tertiary payload.
A satellite repeater that’s handheld accessible.
