ARLA/CLUSTER: Actividade para o próximo fim de semana da ISS em SSTV

[João Costa > CT1FBF]

ISS SSTV activity this weekend

The ARISS Russia Team is planning to support a couple of Slow Scan
Television (SSTV) events in the next few months on 145.800 MHz FM

The first session is being targeted for Saturday, January 16 (may be
subject to change) to celebrate 15 years of ARISS school contacts with
the ISS crew.

The SSTV mode will be PD120 which should allow for the opportunity to
receive more images in a single pass than the PD180 mode used
previously.

The SSTV transmissions will be made from the amateur radio station
located in the Russian Service Module of the ISS using the callsign
RS0ISS. The equipment used for SSTV is a Kenwood D710 transceiver
running about 25 watts output which provides a very strong signal
enabling reception on simple equipment.

A 2m handheld with a 1/4 wave antenna will be enough to receive the
transmissions. In the UK we use narrow 2.5 kHz deviation FM but the
ISS transmits on 145.800 MHz with the wider 5 kHz deviation used in
much of the world. Most rigs can be switched been wide and narrow
deviation FM filters so select the wider filter. Hand-held rigs all
seem to have a single wide filter fitted as standard.
