During Thursday, December 18 the Russian ARISS team members successfully activated the amateur radio Slow Scan TV (SSTV) experiment from the International Space Station (ISS) on 145.800 MHz FM.
Further transmissions are planned for Saturday, December 20, 2014

Among the many radio amateurs receiving the pictures was Frank Heritage M0AEU. His station comprised a 5 element crossed Yagi on a Yaesu 5600B Az/Ele rotator, about 4 metres above the ground, interfaced with a LVB Tracker. Frank used the Ham Radio Deluxe satellite program (v5) for the tracking and a Yaesu FT736R feeding audio to the free MMSSTV software on a Dell laptop.

Martin Ehrenfried G8JNJ used the online SUWS Web-based Software Defined Radio (WebSDR) located near London to receive a number of images during the day. Martin made the 144 and 430 MHz helix antennas for the WebSDR which are optimized for satellite reception. The SUWS WebSDR is available for anyone to use.

The next ISS SSTV transmissions on 145.800 MHz should start around 12:40 UT on Saturday, December 20 and terminate around 21:30 UT.

It is expected SSTV mode will be PD180 with 3 minute off periods between transmissions. A total of 12 different photos will be sent during the operational period.

The transmission will be mode using the Kenwood D710 transceiver located in the Russian Service Module. It is thought the equipment will be producing about 5 watts output which should provide a very strong signal.
