I am interested in building a simple fm reciever using a 74hct4046 pll as a demodulator. The reciever must have a range between 902 and 905 MHz. I guess my question is do I need to mix the input signal down before demodulation? If so, what would be a good frequency to mix down to?
It's also my understanding that this pll can be an fm demodulator and a mixer, but not both, is this correct?
Any thoughts on mixing circuits would be great too.
thanks.
