What do we know about DOKA-B

Hi,

Most satellites that use the Amateur Radio frequenties and send telemetry data can be decoded. The most simple ones use CW and others use for example ax25 packet frames.

The russian satellites that use DOKA-B or a similar methode can, as far as I know not be decoded or are there people that have more information then I could find?

So I have the following questions:

  • Is there a way to decode that transmission methode?
  • And when not, does anybody now why this is not possible?
  • Are there contacts with the russian organisations to get information regarding this subject?
  • Has somebody tried to decode the transmission (I used every SSTV software application I know of, but noting)
