ISS SSTV activity this weekend

From the Southgate Amateur Radio News

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.
