A transmitter for a telegraph receiver in which the bit rate is determined by a high-frequency oscillator and a binary counter frequency divider. The binary counter is reset to an initial condition at the beginning of the transmission of the stop or idle signal after transmission of all of the data bits of a given character. The counter is reset in order to count an initial count of less than its full capability, and the reset of the counter at the end of transmission of a character is delayed for a time equal to the duration of one-half of a data bit. This produces a stop-signal-time that can be controlled from one-half bit in duration, up to 11/2 bits in duration, depending upon the initial reset condition of the counter.
