ARLA/CLUSTER: Emissões em Slow Scan Television (SSTV) nos dias 5 e 6 de Dezembro desde a ISS

[João Costa > CT1FBF]

Slow Scan TV from space Dec 5-6

The 145.800 MHz FM Slow Scan Television (SSTV) transmissions from the
International Space Station Dec 5-6 should be receivable by radio amateurs
around the world

The MAI-75 SSTV system in the Russian Service Module will be put through
some extended testing from December 5 starting around 15:00 UTC and running
until 09:00 UTC on December 6. Test images will be used during this period.

This will provide near global coverage if all works well on 145.800 MHz FM.

In the past images have been sent using the SSTV mode PD180, with a
3-minute off time between each image.

All you need 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 loudspeaker.

The ISS puts out a strong signal on 145.800 MHz FM and a 2m handheld with a
1/4 wave antenna should be enough to receive it.

Many FM rigs can be switched been wide and narrow deviation FM filters. For
best results you should select the filter for wider 5 kHz deviation FM.
Handhelds all seem to have a single wide filter fitted as standard.
