is a mobile 150- W- HF- SSB- transceiver of German origin,
consisting of :
SE 6861 military HF transceiver
FH 6865 mobile mounting
SV 6863 100-W power amplifier
Is the transceiver to be clipped into the mounting 6865. Frequency range is 1.5 to 30 MHz.
For more data see the page of the radio itself (Next page up).

It also is a DC- coupler and a galvanic separation from the mobile power.
The radio SE 6861 is clipped into the mounting, the HF amplifier is clipped on top of the mounting. Mechanical forces are destroyed by special shock absorbers.

Connector to radio SE 6861
Four clips hold th HF amplifier on top of the mounting. The plug "Steuerung (operation)" is connected to its counterpart on the mounting.
HF- input (BNC) of the power amplifier is connected to HF- output of the transceiver.
An ATU can be operated by another plug.
A self- test of the amplifier can be started by a test- button.
Operating conditions are shown by four lamps.

RF 281 A:
is the ATU for the radio set (not in the collection). It is a device of its own; meant for, but not a part of the radio set.
It is used to match rod antennas and wire antennas to the value, tolerated by the power amp.
It is to be mounted next to the antenna and is operated by SV 6863, i.e. it has no operational elements.
