Do you wanna a stereo FM  transmitter with professional quality? 

This FM stereo transmitter, uses advanced modulation system and Phase Lock Loop to control a precise frequency when transmitting.


New low noise system is used to reduce the noise level during broadcasting time.


A digital stereo system is used and control the stereo separation at great condition.with  a high gain antenna ,it can easy broadcast anywhere you want, home , apartment  ,church ,school , club, camping , backyard , resident village.This Broadcast Package is plug and Play design, very easy to use , as you could see you could use it at you really could enjoy the stereo transmitter!


Note: The antenna is NOT included and should be purchased seperatly or made from internet schematics and plans easily!!


* Connect antenna first before connecting transmitter to DC supply, otherwise, transmitter will be burned out.


How far(long) the transmitter cover? 

The transmission range depends on many factors. The true distance is based on the sensitivity of the receiver, antenna of the receiver, and the building and other obstructions, which are between the transmitter and receiver. And the distance will much more in countryside. 





The use of any transmtter radio wave type equipment is the responsability of it's user and NOT Peppers Radio Communication ) In other words, you are responsible what you do with this, and NOT us!!!)  All uses of any transmitter communication equipment are the sole responsibility of the user .
