I recently built an FM transmitter that uses a combination of coil and capacitor as an oscillator to generate the carrier frequency.
I built this transmitter:
Now my problem is that I find it difficult to wind coils properly. The chance of winding properly is very low. I tried to reconstruct nearly 10 to 15 times and it worked hardly twice or thrice. Also the received signal was very faint and consisted of lot of distortion.
Therefore, Now I would like to know if there is a way to build a transmitter that does not involve any coil. I googled it and found that I could use a crystal oscillator or an IC like 555 or LM385, etc.. How can I do it?
