How to Make FM Transmitter

This tutorial is for making simplest FM transmitter using only one transistor. VC1 is a small, screw-adjustable, trimmer capacitor and its rating should be around 10-100pF. Set your FM receiver for a clear, blank station. Then, with a non-conductive tool, adjust the capacitor for the clearest reception, rotate it till the receiver receives a sound from the microphone of transmitter. Use the following formula for determining the frequency.

     USB FM Transmitter
     500mW Broadcast FM Transmitter
     FM Telephone Transmitter
     18W FM Transmitter
     19 KHz MPX Low Pass Filter
     76-110MHz FM Radio Transmitter
     RF Field Strength Meter with Attenuator up to 200 MHz
     Telephone FM Transmitter
     BH1417 Stereo PLL FM Transmitter
     5 Watt FM Amplifier
How to Make FM Transmitter

 

Build Accurate LC Meter and start making your own coils and inductors. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils. LC Meter can measure inductances starting from 10nH - 1000nH, 1uH - 1000uH, 1mH - 100mH and capacitances from 0.1pF up to 900nF. The circuit includes an auto ranging and reset function to make sure the readings are as accurate as possible ... [more]
