ARLA/CLUSTER: ISS activa em SSTV também dia 31 de Outubro

[João Costa > CT1FBF]

ISS Ham Radio SSTV Active *Dmitry Pashkov UB4UAD* reports that the amateur
radio Slow Scan Television (SSTV) experiment MAI-75 on the International
Space Station (ISS) has been active on 145.800 MHz FM

Dmitry also reports that on October 31, 2013 SSTV images
will be transmitted from the ISS on 145.800 MHz showing photographic images
of the life and work of the first cosmonaut Yuri Gagarin.

All you need to do to receive the SSTV pictures from the space station is
to  connected the audio output of a scanner or amateur rig via a simple
interface <http://amsat-uk.org/2011/08/01/1490/> 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<http://hamsoft.ca/pages/mmsstv.php>can be used to decode the
signal, on Apple iOS devices you can use the SSTV
app <http://www.essexham.co.uk/redirect.php?id=sstv>. The ISS Fan
Club<http://www.issfanclub.com/>website will show you when the space
station is in range.
