ABSTRACT OF THE DISCLOSURE In a portable data transmitter which incorporates a pair of tuned circuits, which induce through a transformer a frequency of oscillation in an oscillating circuit, the invention also including the location of switching transistor(s) or other semiconductors which cooperate when turned on to allow the application of power to the various circuitry upon depression of at least one of the tone selection keys of the data transmitter. A second feature of the invention includes the introduction of electrical components into select tuned circuits to prevent frequency pulling or distortion between the pair of cooperating resonant circuits. In addition, the invention contemplates the location of electrical components within a circuit carrying a constant alternating current at the frequency of the generated tone, for example, the collector circuit of an oscillating transistor in the oscillating circuit, and wherein current may flow for operating other transmission component such as a speaker, a remote jack, or any other form of transmitting device.
