RADIO TRANSMITTER DISPLAY INDICATOR

摘要

Apparatus for visually indicating a particular operational condition of a radio transmitter, such as the transmitter being activated or the percentage amplitude modulation of the transmitted carrier. An electrical or electronic character display module having an integral decimal point display portion is utilized to visually indicate a transmitter circuit condition. Transmitter activation may be shown by coupling the push-to-talk circuit to the decimal point display. More specifically, the character display module is oriented to be viewed with the decimal point portion in a superscript position relative to the character. A method for visually indicating the operational status of a radio transmitter includes the steps of providing a character display module having an integral decimal point, generating a signal indicative of a transmit circuit condition, and activating the decimal point display in response to the indicative signal. The indicative signal may be a transmitter activation signal obtained from a push-to-talk circuit or it may be a signal indicating percentage amplitude modulation of the transmit signal. The method also includes the step of orienting the character display module such that it may be viewed with the decimal point portion in a superscript position with respect to the character.
