    It would have been useful to know what the overall project/application is.  Also, where is the transmission occurring and for what distance?  As several folks have pointed out, RF transmission has its downside for various reasons.

     

    If your receiver is always close to the Arduino transmitter (E.g. you could wait until this was true), then one reliable and relatively cheap way to proceed is to create a point-to-point connection using a cross RS-232C cable, either real or (more fun----->) simulated through a breadboard as in https://www.arduino.cc/en/Tutorial/ArduinoSoftwareRS232.  At that URL, you can read the 1970s technology that still works brilliantly.  I won't steal your fun.  In a nutshell, one end is the "data terminal" (E.g. Arduino) and the other end is the "host" (E.g. a PC).

     

    For extra credit and fun, make a permanent cross RS-232C cable with DB-9 connectors at each end.

     

    What do you think about that?
