What you get:
The UHF Quartz Crystal VOX8, Voice Activated Transmitter extended transmitting time and extreme PRIVACY.
This professional transmitter, yet very simple to use , will transmit the quietest sounds to our UHF receiver (or your UHF scanner) with crystal clear results.

Do you like to change batteries? Do you need any transmission when nobody is home? Or at sleeping time? No, it's just a battery waste. This professional transmitter preserves the battery for long time, as the current on "standby" is about 0.8mA - almost nothing!!! When someone begins to speak, the transmitter begins to transmit. A special audio filter make it more sensitive than ever to human voices. A small LED added so you can know when it transmits.
All the components are Military Specs, the best and precise ones on the market. It's a piece of art design !
* Working Voltage: 9V ALKALINE (!!!) battery, you may achieve a long range, depending on the height of the building installed, the walls and the sensitivity of the receiver. It easily penetrates several floors and more.
* Case Dimension: only 4 X 3 cm !
* Long transmitting range: (Up to 1/2mile - 800m - Eye sight on clear)
* Audio Compression: Amplifies weak whispers, suppress high noises !!!
* 20% less current than VOX6 - due to new components.
* SMT built, for more stability and range (MIL SPECS 1% accuracy)
* 7 stages EXTRA amplified output!
* Added one more audio stage - 30% more sensitive than VOX6 - Increased NB. (Narrow-band)
* True NFM - The only one Varicap controlled for power and stability.
* Using a patent pending material for encapsulating, for safety and security !!!
* Ground Plane design, less interferes with other devices - more stability!!!.
* The ONLY ONE that has a frequency range of: 418MHz or 433MHz Crystal Controlled for high stability and PRIVACY.
* Its tiny electret microphone is so sensitive that you will hear a whisper from up to 100 sq. meters (120 sq. yard) around , crystal clear. You won't miss a whisper. USA made by Motorola high amplification microphone.
* The device will work up to 3 weeks connected to a 9V battery (alkaline), depending on the freshness and brand.*
8 User manual is included.
*Please note that transmitting distance vary on different factors. The results you obtain depend very much on the sensitivity of the receiving FM radio, aerial of the receiver, buildings and other obstructions between the transmitter and receiver, atmospheric conditions and other nearby radio station transmissions.
*The calculation on VOX mode for up to 20 days is with a 9V alkaline battery and assuming 2 hours of conversations per day (the total of all the activity of the day).
