I have the same question.
I'm working on a completely remote control Dodge Intrepid. For the radio control system, I'm going to use tones transmitted via amateur radio. For example, there will be a certain tone (maybe 500Hz) for "turn left", and another (600Hz) for "turn right". I was just going to use 555 timers to generate the tones, and then have that go to the mic input on the radio. In the car, LM567's were going to decode the tones and send the appropriate signals to the right systems. My question: Will an LM567 *reliably* decode the square wave generated by the 555? If not, any suggestions of easy ways of doing the same thing?
