ARISS is planning a Slow Scan Television (SSTV) experiment from the International Space Station, scheduled to start on Tuesday, October 8, at 16:00 GMT and running until Monday, October 14, at 14:10 GMT.
There will be an interruption on Friday, October 11, for planned school contacts over Europe.
The SSTV transmissions will be made using the amateur radio station in the ISS Service Module. The transmission frequency will be 145.800 MHz (+/- 3.5 kHz Doppler shift) FM, using SSTV mode PD120.
Many FM rigs can be switched been wide and narrow deviation FM filters. For best results you should select the filter for wider deviation FM. Handhelds generally have a single wide filter fitted as standard.
At 11:29 GMT on Saturday October 5, 2024, an Amateur Radio on the International Space Station (ARISS) radio contact between astronaut Sunita Williams KD2PLB aboard the International Space Station (ISS) and members of Girlguiding Surrey West County, took place at the Brooklands Museum and Brookland Innovation Academy, located in Weybridge, UK.
ARISS conducts 60-100 of these special Amateur Radio contacts each year between students around the globe and crew members with ham radio licenses aboard the ISS.
Girlguiding Surrey West is a charity organization for girls and young women. Girlguiding wants to inspire their members to learn skills in science, technology, engineering and math with fun guiding activities and science-based activities. The Brooklands Innovation Academy, established in 2022, creates inspirational STEM experiences for young people. The age range of the participants for this ARISS contact are 5 to 19 years old. By hosting this ARISS contact they are also demonstrating real-world application of STEM concepts (an important principle at Brooklands Museum) to space missions and are encouraging the girls to complete their space interest badge. The group is being supported by the Radio Society of Great Britain and the ARISS UK Team to establish the radio link.
Girlguiding patron, Her Royal Highness The Duchess of Edinburgh attended the contact to help in promoting the engagement and involvement of girls and young women in STEM. At the start of the contact she greeted Sunita Williams on board the ISS.
This was a direct contact via Amateur Radio allowing students to ask their questions of astronaut Sunita Williams, amateur radio call sign KD5PLB. The downlink frequency for this contact was 145.800 MHz and was heard by listeners within the ISS-footprint that also encompasses the relay ground station.
The amateur radio ground station for this contact is in Weybridge, UK. Amateur radio operators using call sign GB4GGB, operated the ground station to establish and maintain the ISS connection.
The Β Brownies, Guides and Rangers asked these questions:
1. Who or what inspired you to become an astronaut and what advice would you have for any of these girls here today who might want to become an astronaut?
2. Do you have any free time and if so what do you spend your time doing?
3. There are many international time zones so how does time work on the ISS?
4. If you were not an astronaut, what job would you like to have instead?
5. What things do you like to take with you to remind you of home?
6. What is the hardest part of your job?
7. How does the food and drinks do you have in space compare to foods on earth?
8. What do you miss about Earth?
9. How long have you been on the international space station?
10. What was your reaction when you found out you had been selected to fly to the ISS?
11. What stars or other things have you seen in space?
12. Is space hot or cold?
13. Does space smell of anything?
14. How do you sleep in space?
15. What is your favorite planet and why?
16. Have you done a spacewalk? If so, what was it like?
17. The spacesuits look very heavy, are they uncomfortable to wear?
18. What is it like floating in space? Have you ever lost anything from it floating away?
19. What things do you like to take with you to remind you of home?
About ARISS:
Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the ISS. In the United States, sponsors are the American Radio Relay League (ARRL), Amateur Radio Digital Communications (ARDC), Radio Amateur Satellite Corporation (AMSAT), NASAβs Space Communications and Navigation program (SCaN) and the ISS National LabβSpace Station Explorers. The primary goal of ARISS is to promote exploration of science, technology, engineering, the arts, and mathematics topics. ARISS does this by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students. Before and during these radio contacts, students, educators, parents, and communities take part in hands-on learning activities tied to space, space technologies, and amateur radio.

AMSAT-UK is delighted to have been able to accept an opportunity to provide a FUNcube Lite payload, with a mode U/V FM transponder, for the exciting Jovian-1 satellite.
This 6U CubeSat is being designed and built by Space South Central which is the largest regional space cluster in the UK.
This is a partnership between industry and academia, designed to accelerate space business growth, grow the reputation
of the south central region of the UK and foster an environment of innovation.
A collaboration between the universities of Surrey, Portsmouth and Southampton, JUPITER β the Joint Universities Programme for In-Orbit Training, Education and Research β will equip participants with invaluable hands-on space industry experience and training for their future careers.
The FUNcube Lite payload from AMSAT-UK will collect and send telemetry from Jovian-1 sub-systems for educational outreach to schools and colleges, using the tried and tested FUNcube data format.
Telemetry will include data from the payloadβs own radiation sensor, along with GPS information gathered from the satelliteβs CAN bus.
These data can be used to map radiation throughout the orbit, identifying planetary radiation βhotspotsβ such as the polar regions and the South Atlantic Anomaly. It will also give an accurate measure of how much radiation reaches the sensitive electronics within the satellite.
While Jovian-1 and its ground station at Surrey University will use commercial S and X band for primary communication,
FUNcube Lite will use frequencies in the amateur UHF and VHF spectrum.
When not sending telemetry, the payload can be configured as a mode U/V FM voice transponder for amateurs to use for international communications.
More information will be provided during the AMSAT-UK Colloquium taking place during the weekend October 12/13th https://amsat-uk.org/colloquium/

The GreenCube satellite, developed by S5LAB, has likely ceased functioning due to radiation damage. After a successful mission that exceeded expectations, the satellite is no longer responding to commands, and its onboard radio is believed to have been compromised by the harsh radiation environment in Medium Earth Orbit (MEO).
Approximately ten days ago, GreenCube experienced a reboot, and telemetry data from the event did not indicate any anomalies. However, the S5LAB team now suspects that the satelliteβs radio was damaged, leading to the current communication blackout. MEO is notoriously challenging for satellites due to its high radiation levels, and GreenCube was not the only satellite affected. Several other CubeSats launched alongside it only lasted a few days, making GreenCubeβs extended mission duration a remarkable achievement.
Despite ongoing efforts to send commands and reactivate the satellite, the team remains pessimistic about restoring GreenCubeβs functionality. The satelliteβs survival in the hostile MEO environment is seen as a testament to its robust design, but the likelihood of recovery is slim.
At this time, no successor to GreenCube is planned, primarily due to the infrequency of launch opportunities to MEO. Launches to this orbit are rare, which complicates the prospect of future missions.
In response to the satelliteβs success and the interest it generated among radio amateurs, S5LAB has promised to host a webinar in collaboration with AMSAT Italia. The event will provide insights into the GreenCube mission, sharing the challenges and triumphs of the satelliteβs journey. This is an opportunity for the amateur radio community to learn more about the satelliteβs impact and the technical details behind its impressive mission.
While GreenCubeβs operational life may have ended, its contributions to satellite technology and amateur radio will be remembered as a significant milestone.

Every few years the myth that Cosmonaut Yuri Gagarin was radio amateur UA1LO crops up again. This myth started in the early 1980βs and has been debunked numerous times since but it still appears on websites listing βFamous Hamsβ.
This note is in response to several related comments that appeared on the AMSAT-BB last week. Since not everyone reading this BB was radio active back in the 60βs, 70βs, 80βs, and 90βs Iβve included some background information.
The earliest known statement suggesting that Yuri Gagarin was a Radio Amateur appeared in the March/April 1981 issue of Orbit magazine, the primary publication of AMSAT-NA at the time. It was in an article by Joe Kasser, G3ZCZ, [the editor of Orbit] titled βA History of Radio Amateurs in Space β Part 2β. The article stated that Yuri Gagarin, the first person to fly in space, was UA1LO.
1962 UA1LO QSL card published in Orbit magazine issue 6
The evidence provided for this assertion was a QSL card from UA1LO to W8DX confirming a QSO on May 19, 1962 signed βYuriβ. Figures in the Orbit article showed several Russian stamps, and a photo, all featuring Gagarin. Joe never stated that the stamps or the photo were from the back of the QSL card but the reader could easily make that assumption. Joe later reported that the stamps were from his collection. I believe that the photo was on the flip side of the QSL and that the card was probably via the famous Box 88, Moscow.
Needless to say, the article caught my attention. However, after reading it carefully I concluded that this was just a typical UA QSL from the early 60βs. I felt that the fact that the operator happened to be named βYuriβ, a relatively common name, and that the Gagarin photo appeared on the back of the card didnβt justify the conclusion that UA1LO was Gagarin. I have to admit that it occurred to me that, in the QST tradition, the article was an βApril Fool Featureβ (check the publishing date).
UA1LO was Yuri Babkov from St. Petersburg formerly called Lenningrad
Several months after the Orbit article appeared I ran into Joe at an AMSAT Meeting in the MD/DC area and asked him if the article was true. Since this is more than 20 years ago and I have trouble recalling what happened last week I donβt fully trust my memory as to his response but I do remember concluding that the UA1LO β Gagarin connection was probably not valid. Joe states that based on the information he had available at the time he believed the statement to be true β the article was NOT an April Fool Feature.
Shortly after his famous flight into space (April 12, 1961) Yuri Gagarin was declared a βHero of the Soviet Unionβ by the government. This is an honor of the highest order awarded to citizens making outstanding contributions to Soviet culture and life. Perhaps more important, Gagarin was truly regarded as a hero by the general population. Shortly after his flight photos of Gagarin were widely distributed all over the Soviet Union, especially to youth groups and in schools. Itβs very likely that picture postcards with the famous photo were widely circulated.
At the time it was common practice for individual Soviet hams (those with their own stations) to produce QSL cards using linoleum block printing over, or on the flip side of, photoβs of famous people, places or works of art. [At the time most UA activity was from club stations].
Last week I read with great interest the AMSAT-BB note from Frank Cahoy, K0BLT, concerning his 1961 QSL from UA1LO (dated August 18, 1961) with the photo of Gagarin on the back. Frank sent me a scanned copy of the QSL and a translation (thanks to K5OE) of the text printed on the card. The card itself was somewhat different from the one W8DX received but it tends to support the contention that the cards sent to W8DX and K0BLT are generic QSLβs featuring a photo of a very popular Soviet hero from an operator who happened to be named βYuriβ.
The scan of K0BLTβs QSL appears to be a stock postcard featuring a photo of Gagarin with βUA1LO Leningradβ added using Linoleum block (or similar) printing techniques. The Cyrillic text, lower right on the address side, is characteristic of standard postcard printing.
Iβd like to clearly state that there is absolutely NO reason to suspect that UA1LO had any intention of misleading anyone as to his identity. He was simply following common everyday procedures and it probably never occurred to him that his card might cause confusion.
I understand that shortly after Joeβs 1981 article appeared there was an article or editorial by Wayne Green, W2NSD, which also mentioned the βfactβ that UA1LO was Yuri Gagarin. I have not seen this article so I donβt know if it contains any additional facts. I assume that it is based entirely on Joeβs comments. If anyone has information to the contrary please make it public.
For those of you not familiar with Wayne let me say that over a period of several decades he was a very well known and influential commentator on Amateur Radio. His articles, editorials and speeches were often informative and provocative; they were always interesting. However, as a journalist, Wayne made it clear that he considered fact checking a waste of time and he never let facts ruin a good story. Iβm sure that heβd have a good laugh if he knew he was being quoted as an authority on a question concerning historical accuracy.
Leo Labutin, UA3CR, was a key figure in the group of Soviet Radio Amateurs that built and arranged for the launch of the early RS satellites. In about 1989 he made his first trip to the U.S. and I had the opportunityof meeting his Aeroflot flight and acting as his host for a few days before we flew to Atlanta for the AMSAT convention. During the visit I asked him if he knew whether Gagarin was a Radio Amateur β specifically if he were UA1LO. Leo replied that he knew of NO evidence that Gagarin was a Radio Amateur. [His wording was a little more colorful]. I did NOT ask Leo if he knew Gagarin or UA1LO personally so you can choose to consider his comments to be hearsay evidence.
During the mid 1970βs and early 1980βs I had the opportunity to see numerous copies of RADIO, the primary hobby magazine covering electronics and Amateur Radio in the Soviet Union. One of the goals of the magazine was to encourage young people to develop an interest in technical areas by presenting interesting projects and by describing achievements of prominent Russians involved in exciting technical programs. I believe that if Gagarin was UA1LO the fact would have been mentioned often in RADIO. I NEVER saw any mention of Yuri Gagarin being a Radio Amateur in the magazine. Since the sample of issues I saw was limited you are free to conclude that the information in this paragraph is irrelevant.
Over the years the statement that Gagarin was UA1LO continues to resurface. To the best of my knowledge no significant new evidence has appeared during this time.
So β Was Gagarin UA1LO?
My opinion (and it is only my opinion) is that based on the available evidence itβs extremely unlikely that Gagarin was UA1LO. But I am not 100% certain and I am always looking for new βfactsβ.
In the 22 years since that was posted no-one has been able to provide any solid evidence that Yuri Gagarin was a radio amateur.
1963 UA1LO QSL Card from Yuri Babkov
2009 UA1LO QSL Card from Yuri Babkov
Β
The evidence seems conclusive that UA1LO was an amateur radio operator called Yuri Babkov, first licenced with the callsign UA1LO sometime before 1961 and still licenced in 2009, Gagarin died 1968.
There is, however, one aspect that is intriging, it concerns the 73 magazine article mentioned by Martin Davidoff.Β It appeared in the October 1980 issue of 73, a special space and satellite issue, published several months before the mistaken article in Orbit magazine.
It was written by a Werner βMacβ Maurer W1QMS and tells about his trip to Greece on February 12, 1962, to try to sell X-band radars to the police. He describes how he had a brief encounter with Yuri Gagarin on February 13 at the Parthenon. W1QMS claims Yuri told him he held the callsign UA1LO and was a CW operator.
This appears to directly contradict the solid QSL card evidence that UA1LO was held by Yuri Babkob, so why did W1QMS write it?Β It is not implausable he had heard about the QSL cards W8DX and others received and this in turn caused him to completely misremember a conversation with Gagarin when he was writing a story for Wayne Green W2NSDβs special space issue ofΒ 73 magazine. It will certainly have helped his article get published.
There is one tiny link between amateur radio and cosmonaut Yuri Gagarin. shortly after his mission he, along with cosmonaut Titov, visited the Soviet Young Pioneer Camp ARTEK located at Gurzuf, Crimea, Ukraine SSR and his image was used on the QSL card of the campβs amateur radio stationβs, callsign UB5ARTEK, later changed to U5ARTEK.Β He visited again on August 20, 1966, and was shown the club station. He was allowed to use the microphone and gave the callsign as U5ARTEK/KEDR (KEDR had been his callsign during his space mission).Β Source UT7UT http://ut7ut.com/index.php/u5artek/

On May 26, at 1300 GMT AMSAT-LU plans (weather permitting) to launch a balloon carrying a linear multimode transponder Vβ€U, CW, SSB, FM, APRS LU7AA-11 and VIDEO.
It could last 9 hours if it reaches 82,000 feet height landing in Uruguay, or 6 hours landing at GualeguaychΓΊ. The flight has been approved by ANAC/EANA.
An attempt will also be made to launch LU8YY PicoBalloon emitting WSPR at 20m, if the winds help it could go around the world.
In Merlo, from May 24 to 26, presentations will be made to schools and universities. Depending on the weather it could be launched on May 25.
This experience will provide 4 FM channels + 3 CW + 3 SSB + 1 digital channel and 1 SSTV, all simultaneous. It will allow field testing on a balloon the future satellite platforms planned by AMSAT Argentina.
First Newfoundland contact via QO-100 between VO1/M0XUU and G0MRF
On Saturday, May 11, 2024, Gopan VO1/M0XUU (VU3HPF) succeeded in making the first contact from North America through the amateur radio QO-100 geostationary satellite transponder located at 26Β° East.
Gopanβs screenshot of first Newfoundland QO-100 contact
Gopan was in Newfoundland which is just outside the coverage area of QO-100, the elevation at Signal Hill at St. Johns is below the horizon at -0.9Β°.
He used FT-8 to have a trans-atlantic contact with David G0MRF in south-west London. David reported it was tough going with a lot of QSB.
Gopan will be in Newfoundland until May 15.
In a post on X Gopan reported his signal into QO-100 was not strong enough to permit SSB operation.
Dish used by VO1/M0XUU in Newfoundland
The transmit equipment Gopan used comprised, ICOM IC-705 with 2.4 GHz Up-converter from DX Patrol, feeding a homemade 2.4 GHz amplifier delivering 10 watts output to a Helix 2.5 turn YATT design.
The receive side comprised a homemade 10 GHz Down-converter was based on a design by David G0MRF, a modified LNB all controlled by a Leo Bodnar M0XER GPSDO.
The dish was an 80 cm offset.
The software used was SDR Console and Airspy for setting up the station and MSHV in standard mode for FT8/FT4.
After his initial contact with David G0MRF, Gopan went on the work several other stations including Sadan TA4SO in Turkey.
David G0MRF will be joining Graham G3VZV on a QO-100 Dxpedition to Newfoundland from May 15-19.
They are taking enough equipment to enable transmissions on QO-100 using SSB / CW / FT8 / FT4 / Digital Amateur Television (DATV).

Stefan VE4SW reports he will be traveling to Newfoundland and will be using the callsign VO100QO on QO-100 from May 13-17, he writes:
βVO100QO a special callsign for the activation of QO-100 from St Johnβs in Newfoundland will be used by the βAmateur Radio Satellites and Systems β Canadaβ Association starting Monday, May 13, at Signal Hill or another suitable location (weather permitting). Canadian amateur radio operators Stefan Wagener VE4SW and John Langille VE1CWJ will use a 1.8m dish and up to 100W on SSB to reach QO-100 at -1 degree elevation.
We invite all stations and operators in or near St Johnβs to join us in person and be part of the story. We will operate from Monday, May 13th to Friday, May 17th (weather permitting). Contact VE4SW (email on my QRZ page) for local information and timing.
The βAmateur Radio Satellites and SystemsβCanadaβ Association will issue special certificates for successful contacts, and all QSOs will be logged into LoTW. Please see our βVO100QOβ QRZ page for updates starting Sunday, May 12.
We would very much like to acknowledge the support of βDX Patrolβ in Portugal (https://dxpatrol.pt) and AntΓ³nio Matias for his support. We will use the DX Patrol QO-100 Groundstation V2 and other equipment for our attempt!β
During May there are plans for two separate attempts to make contacts from Newfoundland using the QO-100 geostationary satellite amateur transponders.
Newfoundland is just outside the coverage area of QO-100, the elevation at Signal Hill at St. Johns is -0.9Β°, however, contacts have been made from Indonesia at an elevation as low as -1.3Β° so there is a chance of success.
Gopan VO1/M0XUU (VU3HPF) will be in Newfoundland from May 8-15 and will attempt to make QO-100 contacts.
David VO1/G0MRF and Graham VO1/G3VZV will be in Newfoundland May 15-19 and plan to be active on QO-100 using SSB / CW / FT8 / FT4 / DATV.
Rome, April 30, 2024 β AMSAT Italia is proud to announce the acquisition of the quote of property of the IO-117 βGreenCubeβ satellite. The other part of the property remains on behalf of βSapienza Universityβ, Rome, Italy.
A collaborative work of the parts will let the satellite continue the amateur radio operations after the completion of the primary scientific mission. This will definitively avert the satellite decommissioning process by transferring the legal responsibility of the satellite from the Italian Space Agency to AMSAT Italia. Even formally and legally, the satellite, already known with its original name of GreenCube, becomes for the exclusive use of amateur radio. The scientific community continue the study of the behavior of this type of satellite placed in MEO orbit.
GreenCube was designed and developed by Sapienza University, ENEA and University of Naples Federico II for the Italian Space Agency. AMSAT Italia contributed to design the digipeater and supported amateur radio operations. IARU coordinated the use of the operations in the amateur radio frequency bands.
The satellite was carried on the qualification flight of Vega-C launcher on July 13, 2022 from the French Guiana Space Center in Kourou. On October 29, 2022, the on-board digipeater was activated, allowing GreenCube to become the first ham radio satellite to operate in a MEO orbit. Being a radio amateur worldwide success, AMSAT officially designated the satellite as Italy-OSCAR 117 (IO-117).
AMSAT Italia and Sapienza Space Systems and Space Surveillance Laboratory β S5LAB- are now committed to operate the satellite and to continue to offer the service to the amateur radio community.

An ARISS contact is scheduled with students at Mrs Ethelstonβs CE Primary Academy at Axminster Community Academy Trust, Lyme Regis, U.K. at 11:44 BST (10:44 GMT) on Wednesday April 17 on 145.800 MHz FM.
Matthew Dominick KC0TOR
Amateur Radio on the International Space Station (ARISS) has received schedule confirmation for an ARISS radio contact between an astronaut aboard the International Space Station (ISS) and students at the Mrs. Ethelstonβs CE Primary Academy located in Lyme Regis, UK. ARISS conducts 60-100 of these special amateur radio contacts each year between students around the globe and crew members with ham radio licenses aboard the ISS.
Acorn Multi Academy Trust is a small trust of seven schools (Mrs Ethelstons, Axminster, Chardstock, Marshwood, Loders, Thorncombe and Membury) that are situated on the coast of the English Dorset /Devon /Somerset border. Mrs Ethelstonβs CE Primary Academy is hosting this ARISS contact and is directly involved in this project, however children involved are from the 7 primary schools within this Multi-Academy Trust and range in ages from 4-11 years.
This will be a direct contact via Amateur Radio allowing students to ask their questions of astronaut Matthew Dominick, amateur radio call sign KCΓTOR. The downlink frequency for this contact is 145.800 MHz and may be heard by listeners that are within the ISS-footprint that also encompasses the relay ground station.
The amateur radio ground station for this contact is in Lyme Regis, UK. Amateur radio operators using call sign GB4ACA, will operate the ground station to establish and maintain the ISS connection.
The ARISS radio contact is scheduled for April 17, 2024 at 11:44:48 am BST (UK) (10:44:48 UTC, 6:44 am EDT, 5:44 am CDT, 4:44 am MDT, 3:44 am PDT).
On March 27, 2024, Belgiumβs regulator the BIPT published draft restrictions on amateur radio operationΒ in the 23cm (1240-1300 MHz) band.
Belgium is believed to be the first country to propose restrictions on 23cm band operation following WRC-23 ITU-R Recommendation M.2164-0
The new restrictions include:
Class A (equiv UK Full, USA Extra) β size of band reduced from 60 MHz to 8.24 MHz. EME (but not satellite uplink) is permitted 1260-1262 MHz and the antenna elevation must always be more than 15Β° above the horizon and the transmission power is limited to 50 W EIRP. If the elevation is above 55Β° above the horizon, the power is increased to 500 watts EIRP
Class B (equiv UK Intermediate, USA General) β 1296-1300 MHz only
Class C (equiv UK Foundation, USA Technician) β No access (unchanged)

Two more amateur radio satellites, MARIA-G (HADES-F) and UNNE-1 (HADES-E), are planned to launch from the UKβs SaxaVord Spaceport later in 2024.
Previously announced amateur radio payloads on the launch are:
ERMINAZ-1U and -1V from AMSAT-DL
GENESIS-MA and -ME from AMSAT-EA
QUBIK 5, SIDLOC-PQ-1 and -PQ-2 from Libre Space Foundation
MARIA-G
SaxaVord UK Spaceport under construction
A 1.5u Pocketqube. MARIA-G will offer radio amateurs around the world the opportunity to relay FM voice and AX.25 / APRS 300 / 1200 bps communications. The satellite will also transmit telemetry with its status and voice and CW messages. This all will be achieved by implementing a SDR based FM and FSK repeater. The FM / FSK repeater will be available all time and opened by squelch level without the need of a PL tone/CTCSS.
Main mission for MARIA-G is to be a FM repeater but it will also include a simple guess game being implemented by students at Maria Guerrero High School in Collado Villalba β Madrid (Spain). The satellite will send a clue each week in CW so radioamateurs will have to solve the mystery by having all the clues.
A small experiment, developed by Fraunhofer-Gesellschaft research organization (Germany) will also fly on the satellite to make proof of concept transmissions of a TS-UNB waveform from a low Earth orbit. It will transmit a TS-UNB message according to the ETSI standard ETSI-TS-103-357. It is intended solely as a research and development project with no commercial intent, all its data public and open.Β ITU modulation classification would be 100K W2DWW but the bandwidth will be narrowed. The operation of this experiment will be managed by AMSAT-EA.
UNNE-1
A 1.5u Pocketqube. UNNE-1 will offer radio amateurs around the world the opportunity to relay FM voice and AX.25 / APRS 300 / 1200 bps communications. The satellite will also transmit telemetry with its status and voice and CW messages.
This all will be achieved by implementing a SDR based FM and FSK repeater. The FM / FSK repeater will be available all time and opened by squelch level without the need of a PL tone/CTCSS.
A small guessing-game is being implemented by students of Universidad de Nebrija (Spain). The satellite will send a clue each week in its telemetry so radio-amateurs will have to solve the mystery by having all the clues. Game will be detailed in AMSAT-EA and Universidad de Nebrija websites.
The main mission for the satellite is acting as a FM voice repeater although due to its SDR nature it can repeat data too. This satellite is based on the hardware of HADES-D (SO-121) thatβs currently being used to amateurs worldwide. The guess game implemented by the University is a small challenge for the radio-amateurs and its mission is to make the reception of signals from the satellite fun for youngsters, expecting them to be future radio amateurs.
Proposing a UHF downlink, VHF Uplink for FM voice, FSK data up to 1200 bps, APRS up to 1200 bps and FSK telemetry and experimental data up to 1600 bps and CW.
These two satellites are part of the Erminaz mission, a joint effort by AMSAT-DL, AMSAT-EA and Libre Space Foundation. Planning a DLR/ESA launch from the UK SaxaVord Spaceport in Summer 2024 into 500/600 km polar orbit.
S5Lab announcement on X that GreenCube is to cease operation
At 1622 GMT on Thursday, January 25, 2024 @S5Lab posted on X that the GreenCube IO-117 Digipeater would be permanently deactivated on February 5.
Designed and developed by students of Sapienza University of Rome, GreenCube IO-117 was the first satellite to carry an amateur radio payload into Medium Earth Orbit (MEO) β 6,000 km.
After one year and a half of operations, it is time to conclude the GreenCube operations with the planned de-commissioning activities. After the conclusion of the nominal experiment and with the digipeater payload active for more than one year, we will pergorm the passivation operations for the satellite.
The planned passivation operations will be executed on Monday, 5 February 2024, at 00:00 UTC. From that day, GreenCube will be completely passivated and the digipeater will be switched off for good.
We want to thank everyone that endorsed, supported or participated in the mission and the radio amateur community that enthusiastically became a true part of our project. We hope that GreenCube will somehow be part of your memories of radio amateurs, space engineering enthusiasts, and we hope to involve you soon in many more adventures.
Thanks once again for the unbelievable memories shared together⦠See you soon!

Clark sat-1 (AMBITIOUS), callsign JS1YLT, is scheduled to deploy from the International Space Station (ISS) on Monday, December 18, 2023, at 10:15 GMT. The IARU coordinated downlink is 435.130 MHz.
Clark sat-1 (AMBITIOUS) CubeSat
Clark sat-1 is a 1U size satellite is an educational project of students at the Clark Memorial International High School in Japan. As of November 30 approximately 50 students have been involved in the project and a number have an amateur radio license. The satellite will carry out these missions:
1. Optical Camera Mission
Take photos of the Earth and will downlink them in the 435 MHz band (GMSK, 4,800 bps). The downlink schedule will be posted on X (@sat1_AMBITIOUS).
2. Digi-talker Mission
Downlink 40 to 120 seconds long Digi-talker NBFM signal (Voice message or SSTV pictures in Robot 36 format recorded before launch) including the call sign and school name. communications.
In addition to the 4k8 AX25 GMSK telemetry and mission data there will be a CW beacon every two minutes.
Through these missions, the students will be able to improve their amateur radio and satellite communication skills.
The project will also serve as a model showcase for the development of amateur satellites by the younger generation, and stimulate the interest of the younger generation in amateur radio and satellite
We would appreciate if you will report the reception to βclarksat-1@clark.ed.jpβ after receiving those signals.
