Itwas intended to be used in international espionage by the secret statepolice ( tB) and by Spr va 1 (espionage).

2 The transmitter was used in1960 in Congo (Africa), in combination with a Zenith 1000 Worldradio. This receiver was a good alternative to the purpose built agentsradio receivers of the era. It was one of the first easily available com-mercially available short-wave receivers fully built with transistorsoffering good performance. Though missing, it is noted that the asso-ciated power unit had similar dimensions as the transmitter unit.* Kongo is not correct, but the transmitter was given this provisionalname as it had neither a project number nor any other kind of identifi-cation.
