The vehicle wireless station SE-202 / SEF has been developed by Brown Boveri and came in two variants: the "Jeep station" and the "tank hunter station" to be installed in the Panzerjäger "Hetzer" / G-13.
Later it has seen fixed use for training and in "mountain stations" of the Air Force.

The set consists of two metal cases with the receiver and the transmitter and a control unit, which was simple for the "Jeep station" and equipped with an on-board intercom for the "tank hunter station".

The metal containerd of the transmitter and receiver are stored in a equipment bay in the tank destroyer and under metal covers at both sides of the rear sets of the jeep.
The control unit has a simple channel selector to switch one of the channels "A" and "B", a volume control and the one of the tank destroyer a switch and volume control for the "BV" (on-board intercom) at the right side of the front panel
