The Amateur Radio on the International Space Station (ARISS) program is currently running a Slow Scan Television event.

Slow Scan Television is a digital mode that transmits pictures via modulated audio on the amateur radio frequencies. You don't need a license to receive these pictures, just a radio or scanner capable of receiving on 437.800 MHz and a decoding program like MMSSTV - which is free to download.

I have had trouble with good quality reception during the past few days but managed to get 1/2 of a picture the other day.

The event is running for one more day. You can find more information on the transmission schedule here: https://www.ariss.org/ and you can use the pass prediction website www.heavens-above.com to determine the ISS high passes in your area.

For Heavens-above, the ISS is found in the "Amateur Radio Satellites - All Passes" link. Be sure to set your location on the site's upper right hand corner first.

Also, as the ISS passes overhead, you need to tune your radio for doppler shift. Start a bit high at the beginning of the pass, on frequency when the ISS is overhead and low when the satellite is passed.
