Varios ham radio satellites news.
MIST has been an on-going project at KTH for over 10 years, allowing students to develop practical experience in engineering for spaceflight.
According to the project site https://mistsatellite.space/ the satellite is “prepping to launch in 2027”.
Please stay tuned for more updates and information about the amateur radio payload.
Re-port ANS-235:
Two Chinese science-education satellites carrying amateur radio communications systems are scheduled for launch from the Taiyuan Satellite Launch Center on August 25 aboard a Long March 6C rocket.
The first, known as Jing’an Dream Star and carrying the JAMX01 amateur radio payload, is the result of a multi-year education project involving students in Shanghai’s Jing’an District. The project began in 2019 as an effort to give students hands-on experience with satellite development, radio communications, tracking, and spacecraft operations. Students and teachers are traveling to Taiyuan to participate in tracking and control activities associated with the mission.
According to the IARU Amateur Satellite Frequency Coordination database, JAMX01 was developed by students from Jing’an District together with amateur radio participants, with support from the Youngster Activity Center of Jing’an District, Shanghai. The approximately 50-kilogram microsatellite will support telemetry, digital image transmissions, and an FM digipeater. It also carries navigation lights and a kaleidoscope experiment intended for science-education activities.
The following frequencies have been coordinated for JAMX01:
145.950 MHz – FM digipeater uplink
435.075 MHz – beacon and SSTV downlink
435.175 MHz – FM digipeater downlink
435.500 MHz – telemetry downlink
IARU frequency coordination for JAMX01 was completed on January 6, 2025.
Shanghai officials say the spacecraft is expected to operate at approximately 500 kilometers altitude. Project organizers also describe several unusual educational experiments aboard the satellite, including a system designed to make the spacecraft visible as a flashing point of light, a kaleidoscope payload, and recorded youth voices for use in space-based broadcasts.
A second educational microsatellite, BY70-4, also known as 8104, BY-04, and Harbin MicroSat, is expected to fly on the same launch. The spacecraft was developed by the LilacSat Team at Harbin Institute of Technology and has a mass of approximately 18.7 kilograms. SatNOGS lists a high-definition camera, miniature camera, polarization camera, educational display, and short-message transponder among its payloads. The miniature camera is capable of JPEG and SSDV image transmission.
SatNOGS currently lists a UHF telemetry downlink for BY70-4 on 437.443 MHz using 9600 bps BPSK, with a format compatible with ASRTU-1. The spacecraft team has said in the Libre Space Community that BY70-4 is intended to share the frequency coordination previously used by BY70-3, which has reentered. The public IARU coordination database, however, presently shows the 437.443 MHz coordination under BY70-3 and does not contain a separate BY70-4 record. Operators should therefore watch for any additional coordination or operating information issued before or after launch.

Re-post from ANS-214:
On July 7th, 2026, the MARMOTSat satellite was launched on a Falcon 9 launch vehicle from Vandenberg Space Force Base in California. Developed by the University of Victoria Centre for Aerospace Research, the satellite carries a 2m digipeater and beacon, and a 10m beacon, and DVB-S2 video and ionospheric sounding experiments.
At the request of the University of Victoria Centre for Aerospace Research, AMSAT hereby designates MARMOTSat as Canada-OSCAR 128 (CO-128). We congratulate the University of Victoria Centre for Aerospace Research, thank them for their contribution to the amateur satellite community, and wish them continued success on this and future projects.
CO-128 remains in commissioning following its successful launch. Amateurs interested in assisting with payload commissioning can contact the UVic Propagation Laboratory. Frequency and experiment details are maintained at https://www.propagationlab.ca/satellite/ and https://www.marmotsat.ca. Full experiment schedules are expected later in Q3 2026 once commissioning advances.

Repost from ANS-200 but very important to repeat:
The U.S. Space Force’s authoritative satellite catalog entered a new era on July 11, 2026, when newly assigned catalog numbers advanced from the five-digit sequence ending at 69,999 directly to six-digit catalog number 100,000. Space-Track announced the change and advised users to review its Alpha-5 information and frequently asked questions to ensure that Two-Line Element (TLE) and Three-Line Element (3LE) parsers, along with API queries, remain compatible with the expanded numbering system. The milestone marks the beginning of permanent six-digit catalog numbers for newly cataloged space objects.
The milestone was reached with the cataloging of Saramago, also known as Lusíada 3, one of four Portuguese communications satellites developed by LusoSpace. Named in honor of Nobel Prize-winning author José Saramago, the satellite is part of the Lusíada constellation, which uses Automatic Identification System (AIS) and VHF Data Exchange System (VDES) technology to improve maritime safety, vessel tracking, weather reporting, and ocean data services. The transition occurred one day earlier than CelesTrak had predicted.
Although the traditional TLE format has served the satellite community for decades, its fixed-field design was never intended to accommodate six-digit catalog numbers. Space-Track is maintaining compatibility through its Alpha-5 encoding system, while CelesTrak will distribute General Perturbations (GP) data for catalog numbers 100,000 and above using modern formats such as JSON, XML, CSV, and Key-Value Notation (KVN). These newer formats also eliminate the long-standing two-digit year limitation inherited from the legacy TLE format.
CelesTrak began supporting the modern GP formats in May 2020, giving software developers several years to prepare for the eventual transition. AMSAT likewise anticipated the change by introducing GP data distribution through its Orbital Elements service. Joe Fitzgerald, KM1P, AMSAT Orbital Elements Manager, announced that AMSAT would provide orbital elements in JSON, XML, and KVN formats while continuing to publish traditional TLE bulletins indefinitely for satellites cataloged before the six-digit transition.
For most amateur satellite operators, the change will be largely transparent when tracking existing satellites. However, software that assumes all catalog numbers contain no more than five numeric digits may require updates before it can process newly cataloged spacecraft. Developers and operators of satellite tracking applications, automated ground stations, and custom scripts are encouraged to verify compatibility with Alpha-5 encoded TLEs or one of the newer GP data formats.
While the transition may appear to be a simple numbering change, it represents one of the most significant updates to satellite orbital data distribution in decades. As launch rates continue to increase and the number of tracked satellites and debris objects grows, six-digit catalog numbers and modern orbital data formats will ensure the U.S. Space Force’s authoritative satellite catalog continues to support both the amateur and professional space communities for years to come.

Frequencies in each band are shared. The Amateur experiments which use the same frequencies are mutually exclusive and will never be run at the same time.
The Amateur payload is available to be used by all interested and propely licensed parties, gobally. The Amateur payload is the debut of the Modular CubeSat Radio, featuring the RF modules necessary to facilitate MARMOTSat’s Amateur radio and ionospheric science experiments. The MCR configuration for this mission is the core consisting of the SDR, computer and camera, as well as HF and VHF RF front ends, and wire antennas:
