To support everyone interested in such events, the European Space Agency released tutorials about how to receive pictures transmitted over amateur radio by the International Space Station: you can find them on https://issfanclub.eu/2024/11/08/esa-tips-how-to-get-pictures-from-the-international-space-station-via-amateur-radio-2/
It’s always 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 nothing is heard, 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.
