SVR decoding software - this page is a stub

Kelchblatt 1 is a software program for decoding encrypted messages that are sent via tone-coded transmitters in the Short Wave (SW) radio band, used by agents of the Russian foreign intelligence service SVR [1]. It was first discovered in Germany in 2013 [3] and was used in combination with another software program, called Parabola, to encrypt and send messages via a satellite uplink.
