ISS Slow Scan TV on August 27

Dmitry Pashkov R4UAB reports that the Slow Scan Television (SSTV)

experiment MAI-75 on the International Space Station (ISS) may be

active on Wednesday, August 27 using the call sign RS0ISS on 145.800

MHz FM.

A Google English translation of the work plan says “On Gagarin from

Space”. Open gear with ISS RS by amateur radio link to ground receiving stations amateurs around the world images of photographs devoted to the life and work of the first cosmonaut Yuri Gagarin.

It is unclear how long the SSTV transmissions will continue for but the plan shows the Kenwood TM D-700 transceiver being used for a school contact in the Ruzaevo district on Saturday, August 30.

All you need to do to receive the SSTV pictures from the space station is to connect the audio output of a scanner or amateur rig 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 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 so select the wider deviation. 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.

Listen for the ISS SSTV transmissions online using the SUWS WebSDR,
