ARISS is planning another of their popular Slow Scan Television (SSTV) experiment events. International Space Station (ISS) transmissions are scheduled to begin Friday, Feb. 8 at 14:00 UTC and run through Sunday, Feb. 10 at 18:30 UTC on 145.800 MHz FM with the SSTV mode likely to be PD120.
Update Feb. 9: SSTV transmissions on Friday were at very low power, however, full power was restored on Saturday afternoon.
ARISS Slow Scan TV (SSTV) operations is a process by which images are sent from the International Space Station (ISS) via ham radio and received by ham operators, shortwave listeners and other radio enthusiasts on Earth, similar to pictures shared on cell phones using twitter or instagram.
When this event becomes active, SSTV images will be transmitted from the ISS on the frequency of 145.800 MHz using the SSTV mode of PD120.
They can be received using ham radio equipment as simple as a 2 meter handheld radio or a common shortwave or scanner receiver the 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.
Transmissions will consist of eight NASA On The Air (NOTA) images (see https://nasaontheair.wordpress.com/). In additional, four ARISS commemorative images will also be included.
Once received, Images can be posted and viewed by the public at http://www.spaceflightsoftware.com/ARISS_SSTV/index.php In addition, you can receive a special SSTV ARISS Award for posting your image. Once the event begins, see details at https://ariss.pzk.org.pl/sstv/
Please note that the event is dependent on other activities, schedules and crew responsibilities on the ISS and are subject to change at any time. Please check for news and the most current information on the ARISS Twitter feed @ARISS_status or the AMSAT Bulletin Board
You can receive the pictures from the ISS by using the MMSSTV software and an Online Radio (WebSDR). Select a Frequency of 145800.0 kHz and Mode FM:
