The Russian ARISS team members plan to activate SSTV from the International Space Station on Thursday, December 18 and Saturday, December 20, 2014 .

Expected SSTV mode will be PD180 on 145.800 MHz with 3 minute off periods between transmissions. A total of 12 different photos will be sent during the operational period.

The transmission will be mode using the Kenwood D710 transceiver located in the Russian Service Module. It is thought the equipment will be producing about 5 watts output which should provide a very strong signal.

Start time would be around 14:20 UT on December 18 and 12:40 UT on December 20. The transmissions should terminate around 21:30 UT each day.

SpaceX was launching to the ISS this week and any delays could change SSTV operational times.

All you need to do to receive SSTV pictures direct from the space station is to connect the audio output of a scanner or amateur radio transceiver via a simple interface to the soundcard on a Windows PC or an Apple iOS device, and tune in to 145.800 MHz FM. You can even receive pictures by holding an iPhone next to the radio’s loudspeaker.

The ISS puts out a strong signal on 145.800 MHz FM and a 2m handheld with a 1/4 wave antenna will be enough to receive it. The FM transmission uses the 5 kHz deviation which is standard in much of the world.

Many FM rigs in the UK can be switched been wide and narrow deviation FM filters. For best results you should select the wider deviation filters. Handhelds all seem to have a single wide filter fitted as standard.

On Windows PC’s the free application MMSSTV can be used to decode the signal, on Apple iOS devices you can use the SSTV app. The ISS Fan Club website will show you when the space station is in range.

You can receive the SSTV transmissions online using the SUWS WebSDR remote receiver located near London along with the MMSSTV software In the days before the SSTV starts why not practice listening to the ISS packet radio transmissions on 145.825 MHz FM.
