SSTV or slow-scan television (Slow-scan television) - is the transfer of the image of narrowband radio channels in the range of HF or VHF . The transmission of one frame can last up to several minutes and, of course, it is difficult to call it usual television, rather it is a fax. Nevertheless, radio amateurs are quite active in this form of communication.
This Saturday, April 11, 2015 from 13.00 (10:00 UTC) and until 0:00 (21:00 UTC) in Moscow from the ISS , the SSTV will be transmitted to mark the 54th anniversary of the flight of Yuri Gagarin.
Transmissions from the ISS take place regularly and you can look at the images previously accepted by the radio amateurs in this gallery. The transmission will use high resolution SSTV in PD180 mode (resolution 640x496 pixels). Transmissions will be broadcast at a frequency of 145.800 MHz. The previous time, 12 different photos were sent with a pause of 3 minutes between programs. To receive an image, you need a radio with an antenna for a range of 2 meters and a program that converts sound to image.
The method of receiving SSTV does not differ from that described in the article " Satellite - it is very simple " using RTL SDR. For this task, the reception kit is complemented by image decryption software - this is free MMSSTV software .
And the solution to the problem comes down to the previous one.
Those who do not have an antenna or RTL SDR can try using Web SDR - A radio with a web interface located southwest of London (Latitude: 51.23, Longitude: -0.82).
