I am having issues tackling sending data using my own modulation scheme and antennas. The frequency we are using is around 10Mhz. So far my setup is something like this
Arduino -> FM Modulation -> Transmitting Antenna Receiving Antenna -> Demodulate -> Arduino
I am able to get data across but its all over the place. I have been looking at examples like virtual wire with those little transmitter and receivers but those are at 415Mhz and also cannot use my own antennas (they require like 10 cm wire antennas). I have tried to figure out how to do a simple one way communication thing but I keep running into problems on how to handle the timing to interpret incoming data from the transmitter . I have tried trying to figure a way to do something like a simple one way hand shake like 1111101111 then start recording bit data every 10us etc. I feel like I am missing a very obvious answer to this problem.
