1. A method for storing sequences corresponding to minimum and maximum frequencies in maximum and minimum limit locations, respectively, in a frequency hopping transmitter, wherein the transmitter transmits radiowave signals at frequencies determined by an input voltage from a voltage generator received at a frequency adjust input, comprising:

  • (a) producing a series of test data sequences with a microprocessor;

    (b) supplying a series of test data sequences to the voltage generator such that the voltage generator produces a series of voltages, each corresponding to a respective data sequence;

    (c) supplying the voltages from the voltage generator to the frequency adjust input of the transmitter such that the transmitter transmits the radiowave signal at the frequencies corresponding to the voltages;

    (d) receiving with a radiowave receiver the radiowave signals from the transmitter;

    (e) detecting the frequencies of the radiowave signals;

    (f) for the radiowave signal having a frequency closest to, but less than to the maximum frequency, identifying the corresponding data sequence;

    (g) storing the data sequence corresponding to the frequency closest to, but less than the maximum frequency in the maximum limit location;

    (h) for the frequencies closest to, but greater than to the minimum frequency, identifying the corresponding data sequence; and

    (i) storing the data sequence corresponding to the radiowave signal having a frequency closest to, but greater than the minimum frequency in the minimum limit location.
