The transmitter / receiver, mobile SEM 80 is a mobile land radio station and belongs to the SEM 70/80/90 radio family , which replaced the SEM 25 and SEM 35 in the Bundeswehr in 1986 . With the addition of the LV-90 power amplifier assembly, the SEM 80 becomes the SEM 90 . Both are mainly installed in Bundeswehr vehicles (including the Marder armored personnel carrier ) as a troop radio ( mobile land radio service ) and, like the basic model SEM 70, can be operated with manual selection (HW) or automatic channel selection (AKW). Delta modulation is used for speech coding and the data transmission is 16 kbit / s. The device works in the frequency range 30.000–79.975 MHz (VHF troop radio) in the 25 kHz channel grid and thus has 2000 channels.
Relay operation , data transmission, voice and data encryption are possible with additional devices.
