I am trying to make a very low power RF transmitter to set clocks in my house. I have the Arduino code figured out to turn the carrier on and off for the date/time (that was easy). I was thinking of using the NCP1200P60 chip to generate the 60kHz carrier. Admittedly, that is the limit of my RF knowledge.
The NCP is is a DIP8 chip designed to produce a PWM signal at exactly 60kHz. How do I wire it up so that I can dedicate a digital pin on the Arduino to switch that carrier on an off. ... Or am I so far off base that it is a stupid idea?
My understanding of the 60kHz band is that you would have to have a large antenna and a lot of power to cause any interference with the neighbors' clock and I certainly don't want to piss off the FCC ... I just want to periodically (say once a week) send out a weak signal to all of the radio controlled clocks in the house.
I did see the Instructable on the topic using the ATTiny 85
The data sheet for the NCP1200P60 is here.
Am I just crazy to think this is possible?
