ISS SSTV :

The ISS SSTV pictures are transmitted on 145.800 MHz FM. They should be receivable on an Amateur Radio 2 metre handheld or a scanner radio connected to an external quarter wave groundplane or discone antenna. If your radio has different filter settings for 12.5 kHz and 25 kHz FM then select the 25 kHz filter for best results.
