Body wearable covert radio
- under construction
ACACIA-1 1 (Russian: АКАЦИЯ-1), was a miniature
solid-state body-wearable self-contained two-way
covert VHF transceiver,
developed in the late 1970s in the Soviet Union (USSR) for use by Soviet
intelligence services like the KGB.
It was used for observations, surveillance, VIP protection
and other covert operations.
The device is also known as AK PPR-1 (Russian: АК ППР-1).
|
The radio is extremely small for its age, approx. twice the size of a pack
of cigarettes, and can easily be hidden under the operator's clothing, for
example in one of the pockets or in a strap around the neck. It is powered
by an internal cylindrical rechargeable 12.5V battery pack.
The device can be fitted with 5 channels in the 2-metre VHF/H band and has
a combined microphone/speaker that should be hidden under the collar of
the coat. The transmitter is operated by pressing one of the large round
push-buttons on the front face of the device.

The other large push-button is for broadcasting a call-tone that
activates the vibrator of other Acacia radios in the network,
so that its operator is alerted about an incoming call.
The device can optionally be fitted with a wired remote control unit
(not shown here). When this expansion unit is omitted, a shorting
plug should be fitted in the socket (as with the device shown here).

АКАЦИЯ, pronounced ACACIA or AKATSIYA, is the Russian name of
a plant.
