1. A method useful for tuning power levels in a radio telephone having a transmitter and a logic section which controls operation, the method comprising the steps of:

  • supplying a power level from the transmitter to an antenna interface;

    sensing the power level with an external tuning sensor connected to the antenna interface and through an auxiliary interface to the logic section;

    adjusting the power level in a feed-back loop via the logic section based on the sensed power level until a desired tuning result is achieved;

    storing the desired tuning result for the radio telephone as a compensating value in a non-volatile memory within the logic section; and

    controlling a power level of the transmitter via a digital analog converter according to the desired tuning result stored in the logic section when the radio telephone is operating.
