Hello this is my first time posting on here, but i've run into a problem with my FM transmitter. This is the second one i've built using the assistance of an schematic with my own touches to it, but i'm running into the same problem of it transmitting to a higher frequency then needed.
Project:
Two Stage FM Transmitter using an Variable Inductor
Problem:
Broadcasting between 180-200MHz
Need Solution:
Which component will allow me to bring the frequency between 87.5-108.0 MHz
Here is the report I did on my first transmitter...

Here are the pictures of my new project...

the only thing different is an led, 2 AA for a 3v source, and a smaller design.
