When an event becomes active, SSTV images are transmitted from the ISS at the frequency of 145.80 MHz using the SSTV mode of PD120 and can be received using ham radio equipment as simple as a 2 meter handheld radio or a common shortwave or scanner receiver that covers the 2 meter ham band. After connecting the audio output of the radio receiver to the audio input of a computer running free software such as MMSSTV, the SSTV images can be displayed.
In this transmission hams received eight NASA On The Air (NOTA) pictures and 4 ARISS commemorative ones. Did you get any?
