  "Fahrzeugzusatz FZ 52-S"

is the mount for the transceiver SE 52-S/FZ.

It consists of FH 52-S, the holder for the transceiver; and the mount FZH 52-S and serves as connector to

  • NF
  • HF und
  • Data.

  • The battery voltage from 21 to 29 V changes to stabilized 9V to operate the SE 52-S/FZ

  • The power is transient protected.

  • Voltage below 19 V is shown by a luminescent diode.

  • A 1- Watt- NF- amplifier is built in.

  • A data preparing is built in.

    Every BW- soldier had to to with SEM-25/35/52A/52S/70/80/90/52SL. FZ 52-S obviously was used by few soldiers, there are only few hints on where it was used.
    There are rumers that it was used in the tank Leopard.
    Fact is, it was used to connect the guns of a platoon. For this purpose it could be switched to speech or data.
     
    The transceiver:

    A special variant of SEM-52S is used with the mounting, the transceiver

    SE 52-S/FZ/46

    Technical data of the transceiver SE 52-S/FZ/46 are the same as the data of the SEM-52S, but it cannot be switched to low output, like the SEM-52S. Because of higher power consumption the SE 52-S/FZ cannot be used as portable radio.

    The optical difference to the SEM 52-S is a white semi- circle at the base of the transceiver. When inserted, a full circle is formed with the other semi- circle on the mounting. (see picture gallery).

    The antenna is a Fahrzeugantenne FAF-80 (mobile antenna FAF-80), the same as for SEM-80 and SEM-90. When the SE 52 S/FZ is switched on, the mount provides a bias voltage of + 21 to + 29 V for two clipping diodes, supplied via the antenna cable. See also:
