Description. How to make an FM transmitter- easy tutorial. FM Transmitter Page 9 Tips To Make It Work Better Location Optimum placement for the FM Transmitter is usually away from other electronic devices and objects. If your Transmitter is certified as FCC Part 15 compliant, the manufacturer must have a permanently attached antenna, or detachable antenna with unique connectors. ET Q This is basically a simple DIY hobby circuit and you can try it in your home with minimal components. /DeviceRGB In this project, let’s learn how to make a simple “Long-range FM transmitter ” at a low cost using minimal components. What is FM transmitter circuit. 192.18 0 Td The FM transmitter (Frequency modulation) circuit is made up of a single transistor or a BJT. The input audio signal from the mic penetrated to the base of the transistor, which modulates the LC tank circuit carrier frequency in FM format. !!!" FM Transmitters - Example • Assume fc drift 40 ppm/degree (40 x 5.1 = +/- 204Hz) ! Reply. endstream By taking this point into consideration we modulate the frequency of the signal. In this project, we learn how to create a high range FM transmitter, which has the range of 2 kilo meter (2KM) radius. "!!!" Antenna: Use 15cm to 1 meter long wire for antenna.
