Basic RF control transmission
I can buy a 433Mhz transmitter with this range, but they take FSK or ASK modulated signals. From what i can tell, there is nothing simpler than the 'OOK' version of ASK modulation for transmitting signals. If I'm wrong, please correct me. Otherwise, if I'm stuck with FSK or ASK.
I found one site (bottom of PDF: http://www.edn.com/contents/images/101101di.pdf) providing a simple circuit to produce FSK. I was hoping for something simpler, but if you think this is the easiest way, i'll give it a shot.
Can someone guide me towards the correct ICs and circuits to create this project?
Thanks in advance for your help
