Hi

I purchased a cheap FM transmitter for the car but since it is cheap the signal is so low I cannot use it and i would like to boost its output.

From what I read online, there has to be a resistor that limits the output of the signal due to some regulations, however, i could not locate the resistor, nor the antenna.

Would you please be kind in assisting me and help me improve this transmitter?

Thank you in advance.

That is a great way to break the law and cause radio interference to anybody nearby who is listening to an FM radio station or to their low power FM transmitter.

Good luck trying to find the "black box" that reduces the signal strength since yours is different to the Instructable.

It might just be best to remove all the black boxes. I note the recommended method of using wire-cutters.

Also it's a great demonstration of sodering skills
