Radio Input Arduino Possible? (Small Question)

Hello Mem,

This is the modul i have bought at nkelectronics (also a member of arduino.cc forum):
http://www.nkcelectronics.com/fm-receiver-module.html

I already have found some info etc at sparkfun.com:
FM Receiver Module - WRL-08770 - SparkFun Electronics

This is what i want:

I want to use a 3 watt transmitter and want to send different tones at 100Mhz but this is all analog. (An standard sheme for sending) This is what i already have.

The next thing is to receive those tones in data to the arduino and that i can indentify the tones i have send by the analog transmitter.

Greetings,

Christian
