ARISS SSTV Event is Active via RS-38S Satellite

/

ARISS has announced an SSTV event that will be active through 13th December 2025. Rather than transmitting images via the International Space Station, this event's SSTV images will transmit from the RS-38S satellite, also known as VIZARD-meteo.

Images will utilize the Robot 36 SSTV mode and transmit on 437.825 MHz. The series will contain 12 different images and run from 4th December through 13th December 2025.

Certificates will be available from the ARISS website - https://ariss-usa.org/ARISS_SSTV/

RS-38S is a 3U CubeSat created in part by students in Russia and was launched in 2023.

Operators/Monitors Wanted for Meteor Scatter QSO Party

Operators/Monitors Wanted for Meteor Scatter QSO Party

The Ham Radio Science Citizen Investigation is preparing for a series of upcoming meteor scatter (MS) experiments. Operating will take place for 48 hours on 12-13th December 2025 (Geminids).

This is a combination 'special event' and a contest to generate contact data during meteor scatter events using 10 meters and 6 meters. Contest rules can be found at www.hamsci.org/msqp.

Ten meters has not been used much for meteor scatter study due to past symbol rate limits.  But with recent changes in FCC rules, WSJT-X/MSK144 can now be used on HF bands. The HamSCI meteor scatter event will collect contact data from both 10 meters and 6 meters as part of the scheduled events in August and December. Data will be analyzed offline, comparing data from both bands, using both PSK Reporter raw data and operator contact logs from WSJT-X. User data including both logged contact and received reports are necessary for valid experimental analysis. The latter can be provided by any receive system reporting on MSK144 through PSK Reporter.
