I've used this simple setup to receive fm signals. It's audio quality is not that impressive, but short duration voice transmission will be acceptable and I hope at least it'll provide telephone audio quality.

Transistor can be MPF102 or J310 options.

Even though it looks simple it may need some careful adjustments to get alive. Other than this, an easier option is an FM receiver made of TDA7088 being aware of the fact that real and good FM receivers are not an easy task.

I haven't talked about any other receivers. Try the provided circuit else search on google for fm receiver schematics that use IC's. Buy the IC and components and there you go. But I don't think you are serious enough to get one working.

Best idea is to try the above circuit itself. Buy the components and hurry up! Don't waste time simply by annoying messages. Start a dedicated thread if you need any assistance while constructing. It'll receive the audio you are transmitting.

Funny thing is that I don't think OP has made any transmitters till now :D

the other reciever was the one with a TDA7088 IC that i was asking about:)...electric compnonents are quite expensive here thats why i need to be "annoying":) so that i can get as much exact information as i can before going out and blowing stuff with empty mind.wasting both money and time.anyway thanx ill try it out now.

Expensive?
I can buy a Chinese-made "radio" in The Dollar Store for only $1.00. It uses a TDA7088 IC and has extremely poor performance. The "radio" comes with battery cells, earphones and a light that is a flashlight so the "radio" part is free. You might make one of these garbage radios for maybe $30.00 cost for parts.
