    what kind of receiver are you using? AM radio, FM, or a digital receiver you plan to build? You said just talk to someone in the other room through one. So if you use an am radio you need to amplitude modulate the signal, in FM you need to modulate the oscillator to change the frequency and so on. So what is your choice? digital? digital is not needed to send your voice. Please explain more info thanks.
