1. A radio station for transmitting signals, the radio station comprising:

  • a modulator modulating a signal to be transmitted;

    a power amplifier connected to said modulator for amplifying the modulated signal and producing an output power and a test signal;

    a summing device connected to said power amplifier for subtracting the test signal of the power amplifier from a reference signal to generate a control signal;

    an antenna for transmitting and receiving the signals;

    an impedance with a variable reactance being switched between said antenna and said power amplifier;

    an analog-to-digital converter converting the control signal to a digital signal; and

    a processor using the digital signal to change said variable reactance of said impedance.
