Simple FM transmitter

[audioguru]

R1 should be 10k.
The other resistors determine the biasing of the audio preamp transistor that is taught in high school.
Sorry, I am not a teacher for basic electronics.

i want to a design of Simple FM transmitter(by electroMaster). I'm doing project of circus. reply soon.

thaks inf.

I think he has been tasked with building an FM wireless mic. for the Ring Leader to use at their elephant-go-round circus. Normally, he probably follows "behind" the elephants... good English isn't necessary!

thanks. its working and got a new experience.. thinks again..

plz i need simple radio receiver project and simple intercom project

i want simulink this circuit by Orcad.who can u help me?thanks

 

[audioguru]

There are many simulation programs. Yours is an old one that hardly anybody uses today.

can somebody show me the mod4 of audioguru

Still staying one step ahead of the RF cops?

I made the lousy original FM transmittter to prove that its audio preamp transistor is biassed wrong and that its RF oscillator frequency changes all over the place. Then I fixed its problems one-at-a-time.

The final one (mod4) works very well.

I was referring to This Post

Try my FM transmitter. Another Canadian made one and tested its far range. He saw the RF cops in their truck with antennas on top drive past the next day!

I told him that they were looking for me.
