A system, method, and apparatus for keying radio transmitters in data transmission. The invention includes an automated Push-To-Talk (PTT) transmitter keying/enable switch to facilitate data mode communication via radio stations. An embodiment of the present invention provides low latency or delay; independent from other firmware/subroutine layers executing properly; independent of computer ‘power management’ arbitrarily and capriciously shutting down vital parts of the communications chain. The PTT transmitter keying switch includes a buffering resistor to smooth a load impedance and a charge pump power demand of a driving audio input signal. A plurality of charge pump capacitors are configured to store a source charge of the driving audio input signal for the voltage multiplier. A collector of a switch transistor is configured for connection with a PTT input of the radio station transmitter. An emitter of the switch transistor coupled to the ground.
