FM Transceiver

Hi,
I'm very new in this communication principle.

1. I am suppose to design a simple FM transceiver circuit to transmit a voice from a transmitter to a receiver module (speaker) for approximately 5 to 10 meters away.
I really have no idea how to construct this FM transceiver.

2. Can someone also tell me what electronic components should I use.

3. Please try to explain the circuit (design and function) as detail as possible for I'm relatively new to this.

Thanks in advance.

p.s. If possible, please provide a schematic diagram in the explanation.

    Hi,
    thanks for the websites. It's very informative. But is there a specific audio amplifier; frequency modulated oscillator; RF power amplifier, I should use in my FM transmitter?
    Or can I just use any components of audio amplifier; frequency modulated oscillator; RF power amplifier?
    Same question goes to the FM receiver.

    Another question, I don't see any power source in the block diagram the website provided. How can it work without any power source (eg. AA batteries)?
    Are the arrows wires?
    I'm so sorry for asking such simple questions, but I'm really a beginner here.

    I'm thinking of building a simple "walkie talkie" out of electronic components.

    Oh, and I read somewhere that I need a crystal diode. Is this true?
