An apparatus (7) for switching from a first pilot signal and a second pilot signal on a system transporting a plurality of signals. A tuner (30) receives the signals and provides an output signal to a loop compensation circuit (26). The tuner includes a bandpass filter (22) for removing signals other than the selected pilot signal from the output of the tuner. The output of the bandpass filter is provided to a detector circuit (24, 25). The output of the detector is compared with a reference signal (28) by the loop compensation circuit (28). A microcontroller (39) sends a tuning command to the tuner which causes the tuner to switch from tuning to the first pilot signal to tuning to the second pilot signal and also sends a new reference voltage to the loop compensation circuit. Thus, if the input signal changes from analog to digital modulation on the pilot channel, the set-point, or target level of the reference signal, will automatically change to provide the correct value for operation of the circuit. The microcontroller may change the selected pilot signal based upon a command in the input signal or upon an operator command, such as by setting a switch (not shown).
