Russian-named archive of software for a StarTrack SRT series receiver, labelled 2016, with no exact model or version number in the name. The 3.05 MB RAR probably contains a firmware image and possibly upgrade notes. Because the precise model is not stated, open the archive and check the file names or readme against your receiver's sticker before using anything inside. Typical use is restoring a box that fails to boot, through the serial loader or an SPI programmer. Always save the original flash content before writing.
