dc42,
Below is the schematic for the receiver that i have come up with, i still need to adjust the LPF and set the center frequency for the PLL. However overall does this look correct? I have a FT232R for communicating with the computer via USB. The compared binary from the comparator will be fed to the RX terminal as seen below. I assume there is no need to attach anything to the TX since the receiver is only talking to the computer.
