Anti-spy device

detector for radio transmissions

version 4.1

presents an increased sensitivity and functionality, compared to versions 3.хх or older

Radio broadcast detector

Use: Checking home and office for listening devices.

Characteristics: Detects all kinds of micro radio transmitters, working with a minimum power capacity.

Technical information:

For making tests, we've included a micro power generator of sine signal with one transistor in the package. This generator transmits a signal much more lower than that of a radio-controlled toy's remote, or a home radio phone, has a transmit range of not more than 5 -10 meters, and doesn't create any unwanted radio interferences.

The hidden listening radio microphones are usually composed of a more powerful generator, which signal is modulated by frequency, amplitude, phase or width-impulse.

Attention! - The radio transmit detector should be kept at a distance of 4-5 meters away from a working microwave oven. The detector is a sensitive device!
