Looking at the waveforms, you don't get much of one frequency before it switches to the next at 600 baud, so receiving seems challenging to me. Unfortunately, I don't have any information about the receiving circuity. This particular configuration is limited to 8.25 miles, though.
- mjevans 5y agoSynchronization between bits is probably the hardest part; offhand I don't know how to begin looking at that. Within a given bit, given the properties described of the waveforms (one notably less than half the frequency of the other) as well as the tolerances involved; maybe something edge or center-crossing focused. Possibly use the peek or zero-crossing as a switch on a charge accumulation counter and measure with a comparison amplifier of any kind.
