You are invited to upload decoded images in the ARISS gallery, at: https://ariss-usa.org/ARISS_SSTV/ Once you’ve submitted, just clicking on the dedicated button you can apply for the official ARISS SSTV award.
It’s possible to receive the ISS SSTV signal by using the WebSDR at the Goonhilly Earth Station, the audio can then be fed into your PC or Smartphone SSTV App https://vhf-goonhilly.batc.org.uk/
Follow @ARISS_intl on X for official updates, since changes can occur.
Reminder, the images are sent on a (roughly) 2 minutes on, 2 minutes off schedule. So if you don’t hear anything, give it 2 minutes!
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.
You can get predictions for the ISS pass times at https://www.amsat.org/track/
Useful information on receiving the pictures and links for Apps to display the pictures can be found here:

You may be able to get publicity for the amateur radio hobby if you contact your local newspaper and tell them you’ve received a picture (doesn’t have to be perfect) from the International Space Station, see

This price is a limited time offer, after which rates will return to their standard level.
On the evening of Saturday 11th October, AMSAT-UK are holding a Gala Dinner at the hotel. This is a 3 course meal + tea / coffee which is £39.00 per person.
Full details, including menu choices, are available at the AMSAT-UK shop at https://shop.amsat-uk.org/product/amsat-uk-gala-dinner-2025
There are a limited number of available places remaining for the Gala dinner and registration for it closes on Wednesday 24th September at 1800 UTC so be sure to book your place to avoid disappointment.
Please note that you will be required to book a weekend ticket from the RSGB for attendance. Please see the RSGB booking website at https://www.tickettailor.com/events/radiosocietyofgreatbritain/1735267

 on Saturday, September 20.</p>
<p>As part of the RSGB’s National Coding Week activities this year, the RSGB Outreach Team has been working closely with <strong><a href=)
The LoRa Repeater uses Spreading Factor (SF) 12, and Coding Rate (CR) 5 with a bandwidth of 125 kHz. The frequencies are:
Uplink 439.850 MHz use no more than 200 mW EIRP
Downlink 433.850 MHz

 on September 19 at 08:25-09:00 GMT (09:25-10:00 BST, 17:25-18:00 JST) (though the date and time of the deployment are subject to change due to the ISS schedule modification). The deployment event for those satellites will be broadcast via <a href=)
GHS-01 is a 2U size CubeSat equipped with a camera for photographing the earth, a sensor for checking the state of the satellite, and an attitude control device. In response to commands from the ground station, the satellite-mounted camera photographs the earth from space and transmits the image data to the ground. In order for amateur radio users around the world to voluntarily acquire image data taken by this satellite by radio, the date and time of image transmission will be published on the website https://gifuhs2022.wordpress.com/. Also, the satellite carries a digitalker mission. Audio data is transmitted from a ground station and stored in the satellite. The voice data is transmitted from the satellite as an analog FM voice signal, and a message is broadcast from space. The date and time the message will be sent will be published on the website. The satellite was built by Gifu University with technical cooperation for using satellite radio waves with sister schools of universities and high schools such as Lithuania, Australia, Kenya, South Korea, and Taiwan. A downlink on 437.090 MHz has been coordinated with 20 wpm CW, 1k2 AFSK, 9k6 GMSK and digitalker voice.
DRAGONFLY, coordinated by Kyushu Institute of Technology, is part of the Joint Global Multi-Nation Birds Satellite project, BIRDS-X, and funded by Amateur Radio Digital Communications in the U.S. The 2U CubeSat will carry APRS digipeaters on 145.825 MHz, as well as a Store and Forward messaging system. In addition to the VHF APRS frequency, a UHF downlink for CW beacon and telemetry using 4k8 GMSK will transmit at 437.375 MHz. A ground terminal competition will be held on DRAGONFLY. More information is available at https://birds-x.birds-project.com/
STARS-Me2, a 1U CubeSat built by Shizuoka University features an earth observation camera, but the real experimentation takes place on the AX.25 radio downlinks on which those photos are transmitted back to earth. Reception success rates at receiving ground stations will be measured at baud rates of 1.2kbps, 9.6kbps and 115.2kbps. The coding gain of the error correction scheme will be measured on the downlinks. And the reception performance with polarization diversity at multiple terrestrial receiver stations (developed by amateur radio operators) will be evaluated. The goal is to learn more about how large data sets, such as images, are best transmitted from space. UHF downlinks with CW, 1k2 AFSK, 9k6 FSK and 115.2 bps GMSK are coordinated for 437.350 MHz, 437.400 MHz and 437.200 MHz.
RSP-03 is also a 1U CubeSat carrying a camera, but in this case the camera will not be aimed at earth, but at the stars. The main mission is to capture the star data by camera, convert it to “audible data,” and deliver the audio to the ground as a “Stellar Symphony.” After acquiring data of stars and constellations captured by the onboard camera an on-board AI will compose sounds from the star data and transmit it to the ground via an FM Digi-talker. In addition, digital data will be sent using various baud rates and modulation modes, and a digital “QSL card,” stored on the satellite before launch will be transmitted via SSTV after amateurs have uploaded their callsigns from the ground. A downlink at 437.050 MHz will be shared by the FM Digi-talker, 1200 BPS (AFSK on FM), 9600 BPS (GMSK), and 24000 BPS (4FSK, OQPSK). Details are at https://rsp03.rymansat.com/en.
