DESCRIPTION

SET PLL UHF CRYSTAL CONTROLLED RECEIVER AND LISTENING DEVICE EXTERNAL MICROPHONE LM-UHF QUARTZ CRYSTAL STABILIZED



The set LM-UHF contains a high quality UHF audio surveillance combination. It including one covert transmitter and one professional receiver, both of them working on a fixed point of UHF band. The UHF transmitter is featuring a long external microphone, using a 9V battery and the sensitive UHF-433 PLL receiver Ver. 1. The transmitter can be easier concealed due to the external microphone.


The professional spy UHF audio listening device transmit crystal clear voice up to 600 meters away, line of sight. The UHF receiver can pickup voice signals within 600 meters line of sight area.  You can connect voice recorder to UHF receiver.
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 - listening to the conversation and recording at the same time, if it is connected to a recorder.
The PLL UHF CRYSTAL STABILIZED RECEIVER can be used in a room or business, indoor or outdoor. It employs a high sensitivity circuit which allows the user to pick up RF NFM Transmitters from 200m in urban areas and up to 600 m and even more on straight line (Line Of Sight).
