i'm trying to learn how to send a simple signal transmitter to get a signal from a to b...like a beep or tone, not a complex signal like voice or radio. can someone point me in the right direction? what should i be researching? i know that voice can be sent over am and fm frequencies, but if you're just sending a beep (morse code), do you still need to build a complex transmitter? thanks mark
