SET PLL UHF RECEIVER AND VOX9 VOICE ACIVATED BUG TRANSMITTER QUARTZ CRYSTAL STABILIZED

The UHF VOX9 SET combines the miniaturization and power of the UHF VOX9, featuring an external microphone (4mm diameter on a thin cable 6 cm), a flat design and the professional UHF-433 PLL receiver Ver. 1.
The VOX9 main feature is the voice activation, i.e it transmits only when it hears voices. Whenever there is no sound, the built in automatic voice control will switch automatically the micro hidden bug into a standby status. This OPTION will save the battery lifetime and at the same time, it will make the transmitter undetectable. During quiet time, when nobody is at home or during sleeping time, it turns to standby mode, and it draws less than 1mA from the 9V battery.
We are adjusting each set to a 100% matching frequency. This set is using only high grade components, and one of the unique receiver features is: listening to the converation and recording at the same time, if it is connected to a recorder.
The PLL UHF RECEIVER can be used in a room or a business, indoor or outdoor. It uses a high sensitivity circuit which allows the user to receive VOX9 Transmitters from 200m in urban areas and up to 700+ meters line of sight
