FM Transmitter Here is the schematic‚ PC board pattern‚ and parts placement for a low powered FM transmitter. The range of the transmitter when running at 9V is about 300 feet. Running it from 12V increases the range to about 400 feet. This transmitter should not be used as a room or telephone bug. Part Total Qty.

Low Power FM Transmitter Rod Elliott (ESP) Share| [pic] Introduction This article should satisfy those who might want to build a low power FM transmitter. It is designed to use an input from another sound source (such as a guitar or microphone)‚ and transmits on the commercial FM band - it is actually quite powerful‚ so make sure that you don’t use it to transmit anything sensitive - it could easily be picked up from several hundred metres away. The FM band is 88 to 108MHz‚ and although it

gKit 32. TWO STAGE FM TRANSMITTER This Kit is a powerful two stage‚ 9V FM transmitter (Tx) with a range of up to 1 kilometer in the open. It uses an RF transistor in its output stage. Distance of transmission is critically dependent on the operating Conditions (in a building or out on the open)‚ type of aerial used (single wire or dipole)‚ operating voltage (12V is better than 6V) and if the circuit is peaked for maximum performance. The kit is constructed on a single-sided printed circuit board

CHAPTER THREE ANALYSIS AND DESIGN 3.1 INTRODUCTION This chapter deals with the process of obtaining the design specifications of the wireless Frequency Modulated Transmitter with a frequency of 100MHz in a range of 100m under accurate conditions. From the block diagram shown in FIG. 2.1‚ various circuit components are now chosen and appropriate approximate values are now chosen to match its properties as well as perform duties of the stages. The entire system could be grouped into two major stages
