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.

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!
 
There are many simulation programs. Yours is an old one that hardly anybody uses today.
 
Here it is for the 50th time:

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.
