An improved digital radio control including a transmitter and receiver utilizing codes in which a plurality of switches at the transmitter and receiver establish a binary serially transmitted code for energizing only a particular receiver which has its switches set to the same binary code and wherein the different conditions of the binary code depend upon the pulse length such that unique codes can be selected for particular transmitters and receivers so that interference with other systems in the vicinity will not occur.
