PS-002
Sugar cube bug

The PS-002 was a subminiature FM radio transmitter at the size of a sugar cube. It was built during the 1980s and was sold by spy/security shops such as the Spy Shop in Amsterdam (Netherlands). Transmitting devices like this are illegal and were advertised as 'export only'.
 
The image on the right shows the subminiature bug aside a few real sugar cubes. The device is powered by an internal 1.5V button-type battery and has an operational range of 150 (indoors) to 300 metres (outdoors). It is based on a rather simple free-running transmitter, operating at 283.9 MHz, the device is rather instable.

The frequency can be adjusted with a small screw in the bottom half of the device. The conversation in the room is picked up by a sensitive microphone that is located behind a small hole at one of the corners of the unit.

As the device is rather sensitive to the so-called hand effect, it is less suitable for body worn operation. Instead it should be hidden in a room, for example between real sugar cubes. Due to the extremely small size (23 x 23 x 12 mm), it can be built into a variety of concealments. In 1993, the device shown here was sold 'under the counter' for NLG 550 (EUR 200) [1].
