Tech Alert! - Slow scan TV image from the International Space Station





Image received tonight from the ISS on 145.800MHz

Tonight the International Space Station flew over The Peppermint Lounge and transmitted an image from its amateur radio transmitter on 145.800 MHz.  The ISS flies at an altitude around 350-400kms and several nations contribute to its crew, but the USA and Russia seem to be the most prominent.  

Over the years there have been amateur radio operators as part of the ISS crew so there is an established tradition of the ISS operating amateur radio from the station.  Often the astronauts will communicate with school children via amateur radio.  Other times they will transmit images via slow scan TV and the above image is just such an example.

This image has obviously come from the Russian crew and was received by me at around 12.30 am local time.  It appears to mark the anniversary of a Russian, then Soviet aircraft from WW2.

The equipment used was a Yaesu FT 991 transceiver and a Diamond X50A vertical antenna.  The software used is freeware called MMSTV which is very easy to set up on a Windows PC.

Until next time - peace and love.
