how can I create a wireless transmitter that transmits a signal to a wireless receiver ?

the wireless transmitter transmits a signal to a wireless receiver, 30 feet away, and then the receiver makes a noise from a speaker?

the best way to do this is with remote control modules. This would save you a lot time and money on FCC certification fees.

check out www.ramsey.com ramsey electronics.

also google for remote control modules.

you can get modules for 420 MHz, 920MHz. depending on your location would determine the frequency.
