its working fine for me i can transmit say distance is upto 800mts

but if u use yagi antenna u can transmit more upto 2 km
 

You can also try this simple FM transmitter TX200
 

Range depends on many things,for example wifi card has about 150mW output but
if you use yagi with 12 elements range by optical visibility is 500-700m.
So same thing is here...
I think that is something about 500 m maximum with out antenna.
You can of course increse range by changing output transistor with forex...
BF 258(metal case)planatr type or maby use special VHF transistor.
Transmitter is very stable even if is very simple...
I try put them to work one day constantly -on 95 Mhz ,after one day stay on same
frequancy....
 

do u have pcb schematic for this circuit diagram and which type of mic have u used for aduio input????
 

Hello,
I think; all these small FM transmitter are usually installed with some small electret mice...

Hai friends...I remember seeing some where a small FM transmitter circuit whose PCB layout was available with the printed coil. This drastically reduces the tunning problems an average hobbyist faces while building a transmitter. But i couldnt find it arround. Posting the link or the stuff may help the OP and others interested too.
