SET UHF Receiver and Transmitter 3 to 6V NFM
This set incorporates the UHF transmitter's compactness and efficiency (using 3-6V batteries) with the sophisticated UHF-433 PLL receiver Ver. 1.
We're tweaking each set to a frequency of 100 percent matching.
Only high-quality components are used in this set, and one of the receiver's unique characteristics is the ability to listen and record simultaneously when attached to a recording device.
The listening device is a strong audio espionage transmitter with a minuscule microphone and a flexible antenna, that is ideal for covert activity, in a variety of properties and locations.
Frequency drift is prevented and the frequency is stabilized.
It may be hidden within any non-metallic object actually in any place. However, the higher installations are increasing the distance.
A quartz crystal listening device designed specifically for our devices stabilizes the PLL UHF crystal-driven receiver.
It is extremely sturdy, sensitive, and strong due to its unique design.
It comes with a sensitive RF input, fitted with earphones, it becomes one of the greatest receivers for our surveillance bugs and listening devices.
The PLL UHF crystal-controlled receiver may be utilized in a room or office, as well on any part of your living place.
It has a high-sensitivity input circuit that allows the user to hear the small FM transmitter from up to 300 meters away in metropolitan environments (Line Of Sight, depending on terrain).
Receiver's Details
Used for picking up conversations from our medium-power transmitters, the PLL Receiver employs an extra high sensitivity circuit that allows the user to pick up RF NFM Transmitters from up to 300+ meters away. The PLL Receiver / Transmitter set employs state-of-the-art surface-mount technology, making it the most effective wireless audio transmitter of its kind. The area of the UHF PLL Receiver is huge compared to other receivers.
We've designed it, especially for this purpose. It draws considerably less current than any other similar 9V receiver, and at the same time, the stability is not affected. It is crystal stabilized.

Transmitter's Details
Features:
- The spy listening device dimensions are very compact. Easier to conceal.
- The antenna is shorter - less observed.
- Less current drawn from the battery, longer lifetime.
- High-quality precise PCB.
- High-quality golden cover of contact plates and microphone.
- Shock-resistant indestructible design.
- Extremely sensitive internal built-in microphone.
- Crystal frequency stabilization.
Specifications
- Working Voltage: 1 or 2 x 3V Lithium battery (NOT included)
- Dimension: 2.5cm x 2.7cm x 0.6cm.
- Stability: The transmitter has 3 x RF stages buffered output for stability.
- Frequency: NFM (Narrow Band FM) - Frequency range approximately 433.x (Quartz Crystal Controlled ).
- Distance: Long transmitting range. Penetrates through walls and ceilings.
- Safety: Our unique transmitters are using a patent-pending material for encapsulating, for safety and security.
- Power: Up to 20 mW RF output.
- Audio: Internal microphone. High-level difference between noise and transmitted sounds. Its small, 6mm microphone is so sensitive, that it may cover more than 10 meters around, crystal clear. You won't miss any whisper.
- Antenna: flexible wire 18cm full extended.
- Adjustments: No adjustments are required.
The unit is assembled and ready for use.
Just insert one or two 3V Lithium batteries and it will begin to transmit.
