ARLA/CLUSTER: Emissões experimentais desde a ISS

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,
